Embodiment

Following horse back will be described the present invention, embodiments of the invention shown in the drawings with reference to the accompanying drawings more fully.Yet the present invention should not be considered to be limited to embodiment set forth herein.More properly, provide these embodiment, the disclosure content will be detailed and complete and will fully pass on scope of the present invention to those skilled in the art like this.Similar numeral refers to similar element in the accompanying drawing.

Fig. 1 is the schematic diagram according to the cellular satellite radiotelephone system and the method for the embodiment of the invention.As shown in Figure 1, these cellular satellite radiotelephone system and method 100 comprise at least one parts based on the space (SBC) 110, forexample satellite.Parts 110 based on the space are configured in one or more satellite radio telephone forward links (down link) frequency f_DThe multi-section radio telephone 120a, the 120b that go up in comprising one or more satellite radio telephones sub-district 130-130 " " satellite coverage sendradio communication.Parts 110 based on the space are configured in satellite radio telephone return link (up link) frequency f_UThe first radio telephone 120a that goes up from satelliteradio telephone sub-district 130 for example receives radio communication.Ancillary terrestrial network is configured to (be designated as f ' in the satellite radio telephone uplink frequency_U(can and f_UIdentical)) second radio telephone 120 gone up fromradiotelephone cell 130 for example receives radio communications, wherein ancillary terrestrial network comprises at least one ancillaryterrestrial components 140, theseparts 140 can compriseantenna 140a andelectronic system 140b (for example, at least oneantenna 140a and at least oneelectronic system 140b).Therefore, as shown in Figure 1, radio telephone 120a canradio telephone 120b can communicate by letter with ancillaryterrestrial components 140 with communicating by letter based on theparts 110 in space.As shown in Figure 1, based on theparts 110 in space also at satellite radiotelephone frequency f '_UThesecond radio telephone 120b that goes up from satelliteradio telephone sub-district 130 receives radio communication as interference, and this is undesirable.More particularly, with 150 possible interference path is shown.At thispossible interference path 150, carrier frequency f '_UThe return link signal jammer satellite communication of the second radio telephone 120b.As f '_U=f_UThe time, this interference generally can be the strongest, because, under the sort of situation, the parts based on the space that identical return link frequency is used on identical satellite radio telephone sub-district are communicated by letter with ancillary terrestrial components, and can not have the spatial discrimination between the satellite radio telephone sub-district.

Still with reference to figure 1, the embodiment of satellite radiotelephone system/method 100 can comprise at least onegateway 160, and it can comprise theantenna 160a and theelectronic system 160b that can be connected toother network 162 that comprises ground and/or other wireless telephony network.Gateway 160 is also communicated by letter onsatellite feeder link 112 with theparts 110 based on the space.Gateway 160 is also generally communicated by letter onterrestrial links 142 with ancillaryterrestrial components 140.

Also with reference to figure 1, noise killer (IR) 170a can also be located among the ancillary terrestrial componentselectronic system 140b to small part.Alternatively or additionally, noise killer (IR) 170b can also be located among the gatewayelectronic system 160b to small part.In being still other alternative, noise killer can replace noise killer 170a and/or 170b in small part is located at other parts in cellular satellite system/method 100, or provides noise killer again except that noise killer 170a and/or 170b.Noise killer is toparts 110 and ancillaryterrestrial components 140 responses based on the space, and be configured to reduce the interference that comes the free radio communication that receives based on theparts 110 in space, and to small part by second radio telephone 120 in the satelliteradio telephone sub-district 130 at satellite radiotelephone frequency f '_ULast generation.Noise killer 170a and/or 170b are used to the radio communication f ' of the plan of thesecond radio telephone 120b insatellite radiotelephone cell 130 to ancillaryterrestrial components 140_U, second radio telephone is to use satellite radiotelephone frequency f '_UCommunicate by letter with ancillaryterrestrial components 140.

In an embodiment of the present invention, as shown in Figure 1, ancillaryterrestrial components 140 generally more approaches first and second radio telephone 120a and the 120b respectively than theparts 110 based on the space, and the radio communication from thesecond radio telephone 120b was received by ancillaryterrestrial components 140 before theparts 110 based on the space receive like this.Noise killer 170a and/or 170b are configured to generate interference cancellation signals, it comprises the delayed duplicate of at least one radio communication from thesecond radio telephone 120b for example (being received by ancillary terrestrial components 140), and is configured to deduct from the radio communication that theparts 110 based on the space receive that ancillaryterrestrial components 140 receives from the delayed duplicate of the radio communication of the second radio telephone 120b.Can or use other routine techniques that interference suppression signal is sent togateway 160 from ancillaryterrestrial components 140 onlink 142.

Therefore, adaptive disturbance suppresses technology can be used for part elimination interference signal at least, near satellite radio telephone uplink frequency identical like this or other can be used in the given sub-district, is used for radio telephone 120 andsatellite 110 and communicates by letter with ancillary terrestrial components 140.Therefore, all frequencies that are assigned to givensub-district 130 can be used for radio telephone 120 with based on theparts 110 in space with the communicating by letter of ancillary terrestrial components 140.Conventional system can be faced reusing of given satellite cell internal frequency with avoiding, and these frequencies are used for satellite communication in this satellite cell inside.In other words, conventionally, the frequency of having only other satellite cell to use may become the candidate who reuses on the ground of given satellite cell inside.The beam that dependence is provided by satellite system and the spatial separation of beam reduce or minimize the interference level that enters satellite operations from terrestrial operation.What differ widely is that all frequencies that embodiments of the invention can use noise killer to allow to be assigned to satellite cell are used for ground and satellite radio telephone communications.

Embodiments of the invention according to Fig. 1 can result from following understanding: at f '_UGenerally can receive and handle from the return link signal of thesecond radio telephone 120b by ancillaryterrestrial components 140, this with respect to it viainterference path 150 from time that theparts 110 based on the space arrivesatellite gateways 160 early many.Therefore, can eliminate to small part in the interference signal of satellite gateway 160b.Therefore, as shown in Figure 1, interference cancellation signals, for example the ancillary terrestrial components signal of demodulation can send tosatellite gateway 160b by the noise killer 170a in the ancillaryterrestrial components 140, for example, uses link 142.In the noise killer 170b ofgateway 160b, (on amplitude and/or phase place) copy of signal weighting for example can use, and the well-known adaptive transversal filter technology of those skilled in the art forms.Then, from frequency f '_UThe satellite-signal that receives of set (comprise hope and interference signals) in deduct the output signal of transversal filter.Like this, interference eliminated does not need to be reduced in the signal to noise ratio ofgateway 160 desirable signals, because (muting) ground signal of regeneration (for example by ancillaryterrestrial components 140 regeneration) can be used for carrying out disturbing and suppress.

Fig. 2 is the block diagram of adaptive interference canceller embodiment, and it can be arranged in another parts of ancillaryterrestrial components 140,gateway 160 and/or cellular radiotelephone system 100.As shown in Figure 2, one ormore control algolithms 204 well known by persons skilled in the art can be used for adjusting adaptively the coefficient of a plurality oftransversal filter 202a-202n.Can use adaptive algorithm or other technology of for example Minimum Mean Square Error (LMSE), Kalman, Kalman, ZF and/or their various combinations fast.It will be understood by those of skill in the art that the architecture of Fig. 2 can be used with the LMSE algorithm.Yet those skilled in the art it will also be understood that the modification that can carry out conventional architecture is so that other control algolithm.

To describe additional embodiments of the present invention with reference to figure 3, this illustrates the Frequency Distribution of the L frequency band that comprises cellular radiotelephone system forward link and return link at once.As shown in Figure 3, L frequency band forward link (down link) frequency of space to ground is appointed as from 1525MHz to 1559MHz.Land-air L frequency band return link (up link) frequency takies the frequency band from 1626.5MHz to 1660.5MHz.At forward direction with to return between the L frequency band link be GPS/GLONASS radionavigation frequency band (from 1559MHz to 1605MHz).

In detailed description subsequently, for for purpose of brevity, GPS/GLONASS will simply be called GPS.In addition, for for purpose of brevity, acronym ATC and SBC will be respectively applied for ancillary terrestrial components and based on the parts in space.

As known to persons skilled in the art, the GPS receiver may be extremely sensitive, because they are designed to very weak spread-spectrum radio navigation signal operation, these signals arrive the earth from the gps satellite constellation.As a result, the GPS receiver may be very easy to experience in the band and disturb.The ATC that is configured to the frequency of the L frequency band in the radiation forward direction Landsat band (1525MHz is to 1559MHz) can design to satisfy the requirement with ectoparasite emission of GPS strictness with emission filter outside the very sharp-pointed band.

With reference to figure 1, some embodiments of the present invention can provide system and method again, and they can allow ATC 140 itself to dispose with one of at least two kinds of patterns.According to first pattern, it may be mode standard and peak capacity may be provided, ATC 140 sends and from radio telephone 120 receives 1626.5MHzs emission to the frequency range of 1660.5MHz to radio telephone 120 at 1525MHz on the frequency range of 1559MHz, as shown in Figure 3.On the contrary, in second operator scheme, ATC 140 sends radio communication to radio telephone 120 on Landsat band forward link (down link) frequency range of revising.Compare with unmodified Landsat band forward link frequencies scope, the Landsat band forward link frequencies scope that can select to revise is to reduce the interference to wireless receiver (for example GPS receiver of operating) outside Landsat band forward link frequencies scope.

According to embodiments of the invention, can provide the Landsat band forward link frequencies scope of many modifications.In certain embodiments, the Landsat band forward link frequencies scope of modification can be restricted to the subclass of original Landsat band forward link frequencies scope, so that the boundary belt of untapped Landsat band forward link frequencies to be provided.In other embodiments, use all Landsat band forward link frequencies, but be modified to wireless telephonic radio communication in the mode that reduces the interference of wireless receiver, these wireless receivers are operated outside the scope of Landsat band forward link frequencies.Can also use these combination and sub-portfolio and/or other technology, this is with as described below.

It will also be understood that, to will describe about multi-mode ATC 140 in conjunction with the embodiments of the invention that Fig. 4-12 describes at once, ATC 140 can use the standard forward link of Fig. 3 and return link to operate with first mode standard, and the Landsat band return link frequency range of Landsat band forward link frequencies scope that use is revised and/or modification is with second pattern or alternate mode work.So long as wish, these multi-modes ATC can be with second, non-standard pattern work, and can switch to mode standard in addition.Yet other embodiments of the invention needn't provide multi-mode ATC, but the ATC that can provide the scope of Landsat band forward link that use to revise and/or return link frequency to operate.

Embodiment of the present invention will be described at once, wherein, ATC operates with SBC, SBC be configured on first scope of Landsat band return link frequency from radio telephone receive radio communication and in second scope (separating) the transmission radio communication of Landsat band forward link frequencies with first scope to radio telephone.According to these embodiment, ATC is configured to use at least one time division duplex frequency to send radio communication and receives radio communication to radio telephone and in the different moment from radio telephone.Particularly, in certain embodiments, at least one time division duplex frequency comprises the frame that contains a plurality of time slots, uses this time division duplex frequency to send radio communication and receives radio communication from radio telephone constantly to radio telephone and in difference.At least first in the time slot be used for sending radio communication to radio telephone and at least second of time slot be used for receiving radio communication from radio telephone.Therefore, in certain embodiments, ATC uses the frequency from 1626.5MHz to 1660.5MHz to send and receive under time division duplex (TDD) pattern.In certain embodiments, all ATC on the whole network may have the flexibility of described configuration/reconfigure.In other embodiments, it is reconfigurable having only some ATC.

Fig. 4 illustrates satellite system andmethod 400 according to some embodiments of the invention, comprises ATC 140, and it uses carrier frequency f at tdd mode "_U120b communicates by letter with radio telephone.Fig. 5 illustrates the embodiment of tdd frame structure.Suppose full rate GSM (eight time slots of every frame), a TDD carrier wave can be supported four full duplex speech channels of as many as.As shown in Figure 5, ATC 140 is for example sending toradio telephone 120b on No. 0 the timeslot.Radio telephone 120b is for example receiving and is replying ATC 140 on No. 4 the time slot.Can be used for setting up and another wireless telephonic communicates by letter or the like with No. 5 time slot for No. 1.

Be preferably in the carrier frequency that uses under the mode standard from be lower than any protection frequency band exclusionary zone and send Broadcast Control Channel (BCCH) from ATC 140.In other embodiments, BCCH can also be defined as and use the TDD carrier wave.Among arbitrary embodiment in these embodiments, according to the GSM method of setting up, the radio telephone under the idle pulley can be monitored the information and the paging information of BCCH and receiving system level.When the paging radio telephone, system's decision is for setting up the resource that communication link is distributed to what type of radio telephone.No matter distribute the resource of what type to be used for radiotelephone communication channel (tdd mode or mode standard), information sends radio telephone to, and for example, as the part of call initiationc routine, and radio telephone suitably disposes oneself.

Owing to for example LNA level of ATC receiver, the coexistence of tdd mode and mode standard may be difficult on identical ATC.Particularly, suppose the carrier wave of hybrid standard pattern on identical ATC and the carrier wave of tdd mode, during this part (when the TDD carrier wave is used to forward link service (when ATC sends TDD)) of frame, may the bleed receiver front end of identical ATC of enough energy reduces the sensitivity in its LNA stage.

Can operation technique come the ATC energy that 1600MHz partly upward sends in the rejection band, therefore allow the mode standard and the tdd frame of mixing in order to avoid the sensitivity of the LNA of ATC receiver is reduced.For example, isolation between departures ATC front end and the inbound ATC front end and/or antenna system return loss may increase or arrive maximum.Switchable band stop filter can be placed on before the LNA level.This filter can be among incision receiver link during this part (when ATC sends TDD) of frame (before LNA) and disconnect at all the other time durations.Adaptive interference canceller can dispose at RF (before the LNA level).If used this technology, can obtain the inhibition of about 70dB, this can allow the mode standard and the tdd frame that mix.Yet, may increase complexity and/or the cost of ATC.

Therefore, reduce even can reduce or eliminate the sensitivity of the LNA of ATC, it may use quite a lot of special engineering and attention and may not calculate economically.Therefore, it may be pure TDD except that bcch carrier that other embodiment can keep TDD ATC, and bcch carrier may be not used in traffic and just be used for broadcasting in the first of frame, and is consistent with the TDD agreement.In addition, RACH (RACH) burst can be regularly, and they arrive ATC during the second half tdd frames like this.In certain embodiments, can be equipped with all TDD ATC with can response command and reconfigure.

Recognize that fully forward link may use the speed higher than return link during data communication or other application.For example, when carrying out web browsing with radio telephone, click and/or other user select normally to send to system from radio telephone.Yet for the response user selects, this system sends big data file possibly to radio telephone.Therefore, other embodiments of the invention can be configured to allow to use each forward direction GSM carrier frame time slot that increase or maximum quantity to provide higher downlink data rate to radio telephone.

What therefore, when carrier frequency is configured to provide service at tdd mode, make decision possibly: will distribute time slot to be used to forward link service and contribution how much to be used for return link.No matter what decision is, may wish that the TDD carrier wave of all ATC uses is observed, to reduce or to avoid the sensitivity of aforesaid LNA to reduce problem.In Speech Communication, can be at the middle divide forward chain time gap and the return link time slot of frame, because voice activity is a bi-directional symmetrical on adding up usually.Therefore, driven by speech, the center of frame can be the place of dividing TDD.

In order to increase or to maximize the throughput of forward link under data pattern, can on the forward link time slot, use more spectrum effectively modulation and/or agreement, for example EDGE modulation and/or agreement according to the data pattern TDD carrier wave of the embodiment of the invention.The return link time slot can be modulated and/or agreement based on not too spectrum is effective, for example GPRS (GMSK) modulation and/or agreement.EDGE modulation/agreement and GPRS modulation/agreement are well-known to those skilled in the art, therefore need be in this other description.Suppose the TDD carrier wave strategy that EDGE forward direction/GPRS returns, can support as many as (384/2)=192kbps on the forward link and can on the speed of as many as (115/2) ≈ 64kbps, send at radio telephone on the return link.

In other embodiments, also possible is to distribute six time slots of eight time slot frames to be used for forward link and to have only two to be used for return link.In these embodiments, for voice service, consider the character of the statistics symmetry of speech, the return link vocoder may need with the GSM of 1/4th speed comparable, and the GSM operation of rate at full speed of forward link vocoder, each GSM tdd mode carrier wave produces six full duplex speech channels (25% speech capacity is penalized (capacity penalty)).Be subjected to the control of this asymmetrical partition strategy, can obtain the data rate of as many as (384) (6/8)=288kbps on the forward link, and on return link as many as (115) (2/8) ≈ 32kbps.

Fig. 6 illustrates the ATC architecture according to the embodiment of the invention, and via the order of base station controller (BSC) from network operation center (NOC), it can be suitable for configuration automatically between standard GSM and these two kinds of patterns of TDD GSM according to for example.Will be appreciated that in these embodiments antenna 620 can be corresponding to theantenna 140a among Fig. 1 and Fig. 4, and the remainder of Fig. 6 can be corresponding to theelectronic system 140b among Fig. 1 and Fig. 4.If the order that reconfigures when carrier wave is movable and is supporting traffic, occurs for specific carriers or carrier wave collection, via in-band signalling Fast Associated Control Channel (FACCH), can notify all affected radio telephones also on new resource, to reconfigure own and/or switching so.If carrier wave is reconfigured as mode standard from tdd mode, can starts based on for example capacity requirement by NOC and automatically carrier wave be reassigned ATC and/or re-use pattern therefor to suitable mode standard.If on the other hand, carrier wave is reconfigured as tdd mode from mode standard, according to the ATC that can be assigned to suitable tdd mode from the order of NOC automatically.

Still with reference to figure 6, when demodulation carrier wave under mode standard, switch 610 can remain closed.Under tdd mode, when ATC sent, during preceding field, this switch 610 can be opened, and when ATC received, in later half image duration, this switch 610 can be closed.Other embodiment can also be provided.

Fig. 6 supposes that there is N transceiver each ATC sector, and wherein, it is 1 that N may diminish to, because generally wish the minimum value of each carrier wave in sector.Suppose that each transceiver goes up operation and therefore support eight full duplex speech channels of as many as (when under mode standard) at a GSM carrier wave, ignore the expense of BCCH channel.In addition, when under the GSM of half rate pattern, the GSM carrier wave of standard be to can supporting 16 full duplex speech channels, and under the GSM of 1/4th speed pattern, can support 32 full duplex speech channels of as many as.

When being in tdd mode, the quantity of full duplex speech channel may reduce half, supposes that vocoder is identical.Yet constant for keeping the speech capacity under tdd mode, voice service can provide via the GSM vocoder of half rate, descends and almost discover less than quality.Fig. 7 is the block diagram of reconfigurable radio telephone architecture, and it can be communicated by letter with the reconfigurable ATC architecture of Fig. 6.In Fig. 7, provideantenna 720, and the remainder of Fig. 7 can be provided for the embodiment of wireless telephonic electronic system.

Will be appreciated that acquisition reconfigures ATC and wireless telephonic ability according to the embodiment of the invention and may have smallerly and increase on cost.Cost mainly is the disposable engineering cost (NRE) that develops software.Yet, also may produce certain recurring cost, because each ATC and radio telephone may use additional RF filter and some electronically controlled switches at least.All other hardware/software can be shared to the GSM of mode standard and tdd mode.

With reference now to Fig. 8,, with other radio telephone system and the method for describing according to the embodiment of the invention at once.In these embodiments, second scope of the Landsat band forward link frequencies of revising comprises a plurality of frequencies in second scope of Landsat band forward link frequencies, send to radio telephone by ATC with power level (for example maximal power level), this power level reduces as the function dullness of (increase) frequency.More specifically, as described in inciting somebody to action below, in certain embodiments, second scope of the Landsat band forward link frequencies of revising comprises the subclass of frequency of first or second end of close satellite frequency band forward link frequencies scope, send to radio telephone by ATC with power level (for example maximal power level), this power level reduces towards the first or second end dullness of second scope of Landsat band forward link frequencies.Still in other embodiments, first scope of Landsat band return link is included in the L frequency band greater than the satellite frequency of GPS frequency, and second scope of Landsat band forward link frequencies is included in the L frequency band less than the satellite frequency of GPS frequency.Second scope of the Landsat band forward link frequencies of revising comprises that close satellite frequency band forward link frequencies second scope closes on the subclass of frequency of the end of GPS frequency, send to radio telephone by ATC with power level (for example maximal power level), the end dullness that this power level is closed on the GPS frequency towards second scope of Landsat band forward link frequencies reduces.

Be not subjected to the constraint of any theory of operation, will describe the theoretic discussion that the ATC maximal power level is mapped to carrier frequency according to the embodiment of the invention at once.With reference to figure 8, suppose

The mapping of expression from power (ρ) territory to frequency (ν) scope.To be ATC be the power that maybe should send that uses with given radio telephone reliable communication to power (ρ).This power can depend on many factors, and for example radio telephone is to the rank of the obstruction between distance, radio telephone and the ATC two of ATC, channel multi-path decline etc., and therefore, generally will change as the function of time.Therefore, between radio telephone and ATC, control (iteratively) definite general power that uses adaptively via closed power.

Frequency (ν) is the satellite carrier frequency, and ATC uses it and radiotelephone communication.According to embodiments of the invention, mappingIt is the monotone decreasing small function of independent variable ρ.Therefore, in certain embodiments, along with the increase of maximum ATC power, the carrier frequency that ATC is used for setting up and/or keep communication link reduces.Fig. 8 illustrates the embodiment that the continuous dullness of segmentation reduces (ladder) function.Can use other monotonic function, comprise linear and/or non-linear, constant and/or variable decrease.The transmission of FACCH or slow associated control channel (SACCH) message can be used for embodiments of the invention and be beneficial to self adaptation and real-time substantially mapping.

Fig. 9 illustrates the desirable sub-district according to the embodiment of the invention, wherein, for purposes of illustration, has used three power districts to come division of cells with three related carrier frequency (or carrier frequency collection).For simply, the ATC transmitter supposition in idealized cell centre does not have sectorization.In the embodiment of Fig. 9, frequency (frequency set) f_IBe that to be taken from be the topmost portion of L frequency band forward link frequencies collection basically, for example, take from basically part (referring to Fig. 3) near 1559MHz.Correspondingly, frequency (frequency set) f_MTake from the core (referring to Fig. 3) of L frequency band forward link frequencies collection basically.Corresponding with foregoing, frequency (frequency set) f_OBe that to be taken from be the lowermost portion of L frequency band forward link frequencies collection basically, for example, take from part (referring to Fig. 3) near 1525MHz.

Therefore, according to the embodiment of Fig. 9, if within the outer shroud of sub-district, be wireless phone service, so via frequency f_OBe that wireless phone service.This radio telephone, from ATC intra-zone farthest, (possibility) is to the power output of ATC request maximum (or near maximum).The power output request of response maximum (or near maximum), ATC uses the priori of its power to frequency map, for example, three steps of Fig. 9 ladder function.Therefore, ATC is a wireless phone service with the low value frequency of taking from mobile L frequency band forward link frequencies collection lowermost portion, for example, takes from as far as possible the part near 1525MHz.Like this, then, can provide additional protection to any GPS receiver unit (may near ATC).

The embodiment of Fig. 9 can be counted as Utopian, because they are used to the carrier frequency (or carrier frequency collection) of its regional service to be associated with ATC in the concentric ring zone.In fact, the concentric ring zone generally can not be true.For example, radio telephone can be close to the ATC of its service, but because building has obvious obstruction between radio telephone and ATC.This radio telephone, even relatively near ATC, also may be to the power output of ATC request maximum (or near maximum).Consider this point, according to embodiments of the invention, what Figure 10 may illustrate is actual region contour collection, can be used to the frequency dependence connection of its ranges service with ATC.Can next-door neighbour the ATC sub-district in frequency reuse (or frequency set) f_I, because limited geographical span is with respect to distance between the center of housing estate and f_IBe associated.This also goes for f_M

With reference now to Figure 11,, will second scope of the Landsat band forward link frequencies of other modification that can be used by ATC according to the embodiment of the invention be described at once.In these embodiments, at least one frequency (sending to radio telephone by ATC) in second scope of the Landsat band forward link frequencies of modification comprises the frame that contains a plurality of time slots.In these embodiments, it is unoccupied to send in the wireless telephonic frame at least two continuous slots by ATC.In other embodiments, it is unoccupied to send in the wireless telephonic frame three continuous slots by ATC.In being still other embodiment, sending in the wireless telephonic frame at least two continuous slots by ATC is to send with the power lower than remaining time slots in the frame.In being still other embodiment, sending in the wireless telephonic frame three continuous slots by ATC is to send with the power lower than remaining time slots in the frame.In being still other embodiment, lower power time slot is with closer from ATC and/or experience the radio telephone that first of smaller signal jam selects and use, and sends remaining time slot to and/or experience distant from ATC second radio telephone of selecting of strong signal blocking relatively with higher power.

Different is according to some embodiments of the present invention, only to have utilized the part of tdma frame.For example, have only 4 (or last 4 or any continuous four) time slots of beginning to be used to support traffic in the GSM frame of full rate.Remaining time slots unoccupied (sky).In these embodiments, possible loss capacity.Yet, as previously mentioned, for voice service, can call half rate and even the GSM of 1/4th speed come the recovery capacity, speech quality may have some declines.Unemployed time slot is preferably continuous, for example the 0th time slot to the 3 time slots or the 4th time slot to the 7 time slots (or the 2nd time slot to the 5 time slots etc.).For example, may not too wish to use discrete time slot, for example, the 0th, 2,4 and 6 time slots.Figure 11 illustrates time slot (4-7) and four continuous empty slots (0-3) of four uses in the GSM frame.

Experiment finds that according to these embodiment of the present invention, when the interval between the interference burst increased or maximize, it is many that the GPS receiver can be worked well.Be not subjected to the constraint of any theory of operation, this possibility of result is because the relation between multiple cycle (1 millisecond) of the code weight of the C/A sign indicating number of GPS and the GSM burst duration (about 0.577 millisecond).For comprising that alternately the GSM frame of time slot takies, each gps signal sign indicating number cycle can be experienced at least one " collision ", and comprises that the GSM frame of four to five continuous slots takies the enough information that does not have mistake of permission GPS receiver derivation with " tiding over (flywheel) " error event.

According to other embodiments of the invention, the embodiment of Fig. 8-10 can combine with the embodiment of Figure 11.In addition, according to other embodiments of the invention, if because the smaller area of coverage of inner region of sub-district, Fig. 9 or 10 f_ICarrier wave is not fully utilized, and it can be used for supporting the additional traffic on the much bigger outermost regions in sub-district so.

Therefore, for example, suppose f_IEvery frame in have only the beginning four time slots be used for the interior zone traffic.In the embodiment of Fig. 8-10, these four f_ITime slot carries more lower powered burst, for example about 100mW or lower, and may be therefore, it is unoccupied to show as (almost) from the viewpoint of disturbing.Load f with more high-power burst_IThe influence of remaining four (continuously) time slots on the GPS receiver is insignificant, because the GPS receiver can be operated reliably based on the optimum continuous time interval that is taken by four lower powered GSM bursts.Figure 12 is illustrated in carrier wave f_ISupport the embodiment of four low-power (between inner area) users and four high powers (between outside area) user's frame.In fact, embodiment shown in Figure 12 for available may be preferred strategy near the carrier frequency of GPS frequency band.By load carrier frequency fulllyer, these embodiment can avoid capacitance loss improperly.

Experiment finds that the interference from the GSM carrier wave can be optimum relatively to the GPS receiver, is to use in a continuous manner if be no more than 5 time slots in the GSM frame of for example per 8 time slots, can be very useful.Even because when the GSM carrier frequency very is set quite highly near GPS frequency band (closely to 1558.5MHz) and power level, this experiment is found also to be suitable for, so it is particularly useful.For example, fill five continuous slots for every frame, even as ATC during with the 1558.5MHz radiation, the GPS receiver that worst case is measured on whole ATC service area can obtain the sensitivity reduction tolerance limit of 30dB at least.Fill four continuous slots for every frame, even as ATC during with the 1558.5MHz radiation, the GPS receiver of measuring under the worst case can obtain to increase the sensitivity reduction tolerance limit that 10dB adds up to 40dB.

May still will be concerned about the potential loss (especially under data pattern) of network capacity, this can go up at frequency separation (wherein the embodiment of Figure 11 is used for incomplete infilled frame) and produce.In addition, even the embodiment of Figure 12 can avoid capacitance loss by filling carrier wave, be subjected to the constraint of filling up frame with low-power user and high power user, they also can produce the potential loss of network capacity.In addition, if forward link carriers is limited to 5 continuous high power time slots of every frame, target can be that the maximum forward link data rate of each carrier wave of specific user may tail off pro rata so.

Therefore, in other embodiments, be subjected to the carrier wave of continuous sky/low-power time slot control to be not used in forward link.Alternatively, they are used for return link.Therefore, in certain embodiments, be the data rate maximum on the forward link that allows to spread all over whole network, at least a portion of ATC is configured to the reverse-frequency pattern Comparatively speaking with SBC.On the reverse-frequency return link, it is 5 time slots of every frame that radio telephone can be restricted to maximum, and this can be enough for return link.On reverse-frequency return link carrier wave, 5 available time slots of every frame are assigned to a radio telephone or to five different phones, in these embodiments, they can be specified continuously.As described in conjunction with Figure 12, these five continuous time slot can be assigned to the high power user and remaining three time slots can be used to low-power user service.

Other embodiment can be based on operating ATC comparing under the reverse-frequency pattern with SBC fully.In these embodiments, ATC sends on satellite return link frequency and radio telephone is replied on the satellite forward link frequencies.If exist enough continuous frequency spectrums to support CDMA technology, and the 3G standard of especially supporting emerging wideband CDMA, the ATC forward link can increase or the maximum data throughput ability based on wideband CDMA so.It may be not problem that GPS disturbs, because in these embodiments, ATC sends on the satellite return link.Alternatively, interference may become the problem of radio telephone care.Yet based on the embodiment of Figure 11-12, radio telephone can be configured to send GSM, is lower than forward link rate because under any circumstance all wish ATC return link speed.Therefore, the ATC return link can adopt the data pattern based on GPRS, possibility or even EDGE.Therefore, according to the embodiment of Figure 11 or 12, can be not to fully loaded to solve the GPS interference problem at the return link carrier wave in the preset frequency interval range of GPS band edge 1559MHz.

At last, other embodiment can use part or complete reverse-frequency pattern and can use CDMA on forward direction and return link.In these embodiments, utilize the frequency (1626.5MHz is to 1660.5MHz) of satellite return link and use the frequency (1525MHz is to 1559MHz) of satellite forward link from wireless telephonic ATC return link to wireless telephonic ATC forward link.The ATC forward link can be based on the CDMA technology (for example IS-95, wideband CDMA etc.) in existing or the exploitation.ATC network return link also can suppose that selected the passing to of wireless telephonic output stops transmission based on the CDMA technology in existing or the exploitation, and every T millisecond once continues about 3 milliseconds.In certain embodiments, T will be more than or equal to 6 milliseconds.

May not need this gating for about 1550MHz or following ATC return link carrier wave.For near the GPS receiver the ATC, this gating can reduce or minimize outer (sensitivity reduction) effect of disturbing of band.In order to increase benefit to GPS, the gating between all radio telephones on the whole ATC service area can be synchronous basically.Can give the additional benefit of GPS from the gating synchronization gain of system scope.ATC can indicate the time of occurrence of all movable relevant gating signals of radio telephone.All ATC can be via the GPS manual synchronization.

According to other embodiments of the invention, can suitably make the parts based on the space form required size, radio telephone there is no need to use big antenna 1536 maybe there is no need radiation when being in ground mode when being in satellite mode any more power like this.The link robustness of appropriate level can obtain via the spot beam gain, and the spot beam gain can be provided by bigger satellite antenna and/or other technology.This can compensate the decline (when removing big satellite antenna from radio telephone and/or use individual antenna to be used for ground communication and satellite communication, this situation may occur) of some dB of satellite link robustness incessantly.Therefore, can provide the radio telephone of single pattern and single frequency band, they can be communicated by letter with ancillary terrestrial network with the parts based on the space on single frequency band and single air interface.

Be used for the set radiant power control of multiband/multi-mode satellite radiotelephone communications systems and methodSystem

Multiband/multi-mode satellite radiotelephone communications systems and method according to other embodiments of the present invention will be described at once.

Particularly, with reference to Figure 18, satellite radiotelephone system comprises theparts 1610 based on the space, and it is configured to communicate by letter on a plurality of frequency bands and/or a plurality of air interface with the multi-section radio telephone.Use the link of a plurality of frequency bands and/or air interface in Figure 18, to be labeled as 1880a-1880f, can use still less or more frequency band/air interface although will understand.Ancillary terrestrial network (ATN) 1850 be configured on the ground with the multi-section radio telephone in a plurality of frequency bands and/or a plurality of basically air interface communication basically.Will be appreciated that in Figure 18,5 ancillary terrestrial components (ATC) 1852a-1852f is shown, although inancillary terrestrial network 1850, can adopt still less or more ancillary terrestrial components.As has been described, can also providesatellite gateway 1660 and PDN/PSTN 1810.

Still with reference to Figure 18, provide setradiant power controller 1820, it is configured to the wireless telephonic set radiant power of multi-section is restricted to the maximum set radiant power.In certain embodiments, set radiant power controller is configured to control a plurality of with the frequency radio telephone, to be restricted to the maximum set radiant power with a plurality of with the wireless telephonic set radiant power of frequency.As used in this, what " with frequently " meaned that radio telephone uses is identical carrier frequency, is different tdma slot (different TDMA channels) or what use is different CDMA spreading codes (different CDMA Channel) even their use.Therefore, can continue to observe the radiation requirement of ancillaryterrestrial network 1850, even ancillaryterrestrial network 1850 has adopted a plurality of frequency bands and/or air interface.Will be appreciated that setradiant power controller 1820 can be used as individual components, provides as the part ofgateway 1660 and/or as the part of another parts of satellite radiotelephone system and/or ATN.

In some embodiments of the invention, setradiant power controller 1820 is configured to allow to all basically ATN of communicating with and/or all basically radio telephone control.Yet in other embodiments of the invention, setradiant power controller 1820 is configured to the set radiant power of the wireless telephonic subclass of multi-section is restricted to the maximum set radiant power.For example, in certain embodiments, a plurality of frequency bands comprise first frequency band and second frequency band, and the wireless telephonic subclass of multi-section comprises on the ground radio telephone of communicating by letter with ancillary terrestrial network on first frequency band basically.In certain embodiments, first frequency band comprises the frequency of L frequency band, and in certain embodiments, second frequency band comprises the frequency of S frequency band.In other embodiments, first frequency band comprises the frequency of L frequency band, they basically between radio horizon (inter-radio-horizon) fully used by another system, and second frequency band comprises the frequency of L frequency band, and they are not fully used by another system between radio horizon basically.In these embodiments, second frequency band also can comprise the frequency of S frequency band.

Therefore, in certain embodiments, have only first subclass of ATN and/or the radio telephone that communicates with can be gathered radiant power and controls, and second subclass of ATN and/or the radio telephone that communicates with needn't be gathered radiant power and controlled.For example, the potential interference that causes another system of the frequency of the L frequency band of radiation on ground possibility, and can be gathered radiant power power.On the contrary, according to embodiments of the invention, do not have the frequency of the S frequency band that between radio horizon, fully used basically and may not can the potential interference that causes another system of frequency of L frequency band, and therefore can not gathered radiant power and control by another system.

More specifically, the moving satellite system (MSS) that comprisesATN 1850 can use the air interface protocol more than to provide speech and/or data service to end subscriber at its area of coverage.Division that known U.S. radiotelephone communication market is present and potential following uncertainty may wish that system can provide professional to end subscriber via some air interface protocols.At present, can provide service to U.S. market by iDEN, GSM and Cdma2000, but other emerging standard, and for example W-CDMA and/or OFDM/OFDMA can be used in the future.Be suitable for a plurality of present standards (air interface protocol) and can adapt to future (expection at present or the do not have at present) system architecture of technology the flexibility of increase can be provided.

Figure 18 illustrates the possible deployment schemes that is used for ATN.As shown, can pass through ATC1852a-1852f (they use different air interface protocols) is the service of different and/or overlappinggeographic area.Satellite 1610 can transmit a plurality of agreements to a plurality of agreements ofsatellite gateway 1660/ transmission fromsatellite gateway 1660, and transceiver unit collection different insatellite gateway 1660 can be associated by the air interface waveform different with processing.Radio telephone can comprise integrated transceiver, and it can be viasatellite 1610 or via at least one ATC 1852 and may be according to for example communicating by letter with the business relations that other cellular carrier is set up on other PCS/ cellular band.The satellite of radio telephone transceiver/ATN part can utilize substantially the same air interface protocol with viasatellite 1610 or via at least one ATC 1852 communication.By increasing integrated level and to the reusing of the hardware and software that is used for satellite mode and ATN pattern, this method can reduce or minimize size, weight and/or the manufacturing cost of transceiver.

In some embodiments of the invention, ATN can be based on the CDMA air interface protocol, and do not produce any greater than Federal Communications Committee about interference potential based on the rule of the ATN of GSM.Referring to, report and the rule and the notice FCC03-15 of Rulemaking are proposed, be that mobile-satellite service provider in 2GHz frequency band, L frequency band and the 1.6/2.4 frequency band provides the flexibility of communicating by letter, IB case 01-185 (passes through on January 29th, 2003, announce on February 10th, 2003), after this be called " FCC 03-15 ".Therefore, the technology of any one use among ATN or its ATC can be incoherent, as long as control sets contract emitting stage frequently, in order to avoid exceed the limit that the specific gsm system committee that considers proposes in FCC 03-15.After this manner,ATN 1850 can be developed to a plurality of air interface protocols and act on simultaneously, as long asATN 1850 observes the set radiated power spectral density limit (that is-53+10log (1,725) dBW/Hz) that is proposed by the committee.

In FCC 03-15, the committee allows US ATN that 1,725 times ground of GSM carrier wave is reused, and this GSM carrier wave also is used for satellite communication by MSS.Single fully loaded GSM carrier wave on the ATC return link can be to the maximum to spatial emission-power spectral density of 53dBW/Hz, and this carrier wave is radiated the base station from some radio telephones (eight ones of as many as).Therefore, can the maximum set power spectral density from the fully loaded return link GSM carrier transmit of 1,725 cochannel to the space be-53+10log (1725) ≈-20.64dBW/Hz.This is based on the gsm wireless phone peak E IRP of 0dBW, and is consistent with the analysis of FCC03-15.It is exactly the noise floor similar 0.7% that this maximum set power spectral density of drawing of the committee (allowing the frequency reuse of US scope to produce on return link by the maximum to ATN) may improve the satellite receiver of Inmarsat potentially.

The maximum EIRP of CDMA return link sign indicating number (user) can be-10dBW, and can transmit on the carrier wave of the bandwidth that takies 1.25MHz, according to for example cdma2000 air-interface standard.Therefore, the power spectral density of-10-10log (1,250,000) ≈-70.97dBW/Hz can be transmitted in the space by the single CDMA sign indicating number of operating on the ATC return link (user).As mentioned above, therefore the maximum set power spectral density limit-20.64dBW/Hz of permission can hold about 10^{[(70.97-20.64)/10]}The CDMA sign indicating number of 107,894 cochannel return links of ≈.For the ATN return link, this result can be used for setting up the equivalence relation between pure GSMATN and the pure CDMA ATN.

Therefore, angle from set return link interference power spectrum density, ATN can regard about 107,894 sign indicating numbers (user) that are equivalent to transmission US scope on the CDMA of given 1.25MHz carrier wave as to the frequency reuse of 1,725 times US scope of GSM carrier wave.Number of users is generally less than or equals the quantity of sign indicating number because can distribute to the user more than one sign indicating number to improve reliability and/or message transmission rate.Described equivalence is based on the peak value return link EIRP of the GSM that is assumed to 0dBW, and the peak value return link EIRP of CDMA sign indicating number is assumed to-10dBW.

Can set up the mathematics equivalence between the CDMA sign indicating number (user) of (transmission) GSM time slot (user) of single-unit activity and a plurality of activities, the GSM time slot sends on the 0dBW at peak E IRP, and each comfortable peak E IRP of the CDMA sign indicating number of a plurality of activities promptly-the last transmission of 10dBW.This relation can allow to launch to comprise the ATN of GSM and two kinds of technology of CDMA, and allow the potential fluctuation of capacity between the two, and from the viewpoint of set return link interference power spectrum density current potential (potential), the pure gsm system that the committee that is equivalent to proposes in FCC 03-15.

Particularly,, on given GSM carrier wave, 1,725 * 8=13 is arranged according to FCC 03-15,800 GSM time slots (user) (can be movable at ATN (the US scope)), keeping the noise current potential that arrives the Inmarsat satellite receiver simultaneously increases by 0.7%.Illustrate in the above, from the viewpoint of set up-link power spectrum density interference potential, this is equivalent to about 107,894 sign indicating numbers (user) and goes up transmission at the CDMA of given 1.25MHz carrier wave (the US scope).Therefore, the same frequency GSM time slot (user) of an activity equals the same frequency CDMA sign indicating number (user) of 7.8184 activities of about 107,894/13800 ≈.Therefore, the equation that can be used for controlling the same frequency ATN operation that spreads all over the U.S. can be:

N_GSM+13,800N_CDMA/107,894＝13,800. (1)

In equation (1), N_GSMThe quantity of the same frequency GSM time slot (user) of expression activity and N_CDMAThe quantity of the same frequency CDMA sign indicating number (user) of deputy activity.In certain embodiments, N_GSMIndividual GSM time slot is to small part and N_CDMAIndividual CDMA sign indicating number is with frequently.Because 6 different GSM carrier waves are arranged, they can be frequently same with the CDMA carrier wave of single 1.25MHz bandwidth, so, 13,800N_CDMA/ 107,894 same amount, frequency CDMA carrier wave loads the capacity of the US scope of the GSM carrier wave that will exhaust whole 6 corresponding (with CDMA carrier wave frequency together) together.Based on foregoing, as can be seen, and only under the condition that equation (1) substantially satisfies, the ATN network of US scope (being configured to support GSM and cdma2000 telephone traffic simultaneously) can be observed the uplink channel interference constraint (influence to for example Inmarsa is no more than 0.7% Δ T/T) of the committee.By distributing total with telephone traffic frequently among this class ATN according to equation (1) substantially, MSS/ATN operator can observe.

As previously discussed, fully loaded GSM return link carrier wave (all eight time slots are all occupied) can produce-the maximum EIRP density current potential of 53dBW/Hz.This result is based on antenna gain with 0dBi for example and goes up radiation peak in the carrier bandwidths (supposition of FCC in according to FCC 03-15) of 200kHz is gsm wireless phone/wireless terminal of the EIRP of 0dBW.

Can with have the cdma2000ATN wireless terminal of 0dBi antenna gain for example can limit (intentionally) to maximum for for example-EIRP of 9dBW, use single code communication simultaneously.The carrier bandwidths of known cdma2000 (1xRTT) is 1.25MHz, and the maximum EIRP density that can be produced by single cdma2000 return link sign indicating number can be-9-10log (1.25 * 10⁶) ≈-70dBW/Hz.Therefore subsequently, 10^[(70-53)/10]50 same cdma2000 sign indicating numbers frequently of ≈ can produce identical uplink channel interference power spectral density current potential as a fully loaded GSM carrier wave.

For W-CDMA, the ATN wireless terminal restriction (intentionally) with 0dBi antenna gain for example to maximum for for example-EIRP of 9dBW, use single code communication simultaneously.The carrier bandwidths of known W-CDMA is 5MHz, and this class wireless terminal can produce-9-10log (5 * 10⁶) the EIRP density current potential of ≈-76dBW/Hz.Therefore, 10^[(76-53)/10]200 same W-CDMA sign indicating numbers frequently of ≈ can generate identical uplink channel interference power spectral density current potential as a fully loaded GSM carrier wave.

For the ATN that can be based on all three kinds of technology (GSM, cdma2000 and W-CDMA), following constraint equation can be used for determining distributing with the permission of telephone traffic frequently with the skyborne of these three kinds of standard association:

N/8+M/50+L/200=R (2) wherein N represents when using and reuse given GSM carrier wave quantity by this carrier wave same frequency GSM time slot that support, the ATN scope, M represents when spreading all over ATN uses and supported by this carrier wave when reusing single cdma2000 carrier wave cdma2000 with the quantity of sign indicating number (channel) frequently, L represents when being used by ATN and reuse single W-CDMA carrier wave on this carrier wave W-CDMA with the quantity of sign indicating number (channel) frequently, and R represents the pure ATN frequency reuse based on GSM of being authorized by FCC.In certain embodiments, N GSM time slot, a M cdma2000 sign indicating number and L W-CDMA sign indicating number to small part with frequently.Notice that above-mentioned equation can provide constraint, this constraint can be applied on the carrier wave with operation frequently (all these three kinds of carrier type GSM, cdma2000 of the telephone traffic of the ATN scope of distributing according to above-mentioned equation and W-CDMA can with operation frequently).In addition, launch for pure ATN based on GSM, above-mentioned equation is reduced to N=8R (M=L=0), the octuple of the frequency reuse that time slot (channel) sum that this single GSM carrier wave that meets the ATN scope can be supported equals to authorize.

Because 6 GSM carrier waves are arranged, they can be in the bandwidth of single cdma2000 carrier occupancy, so with the same amount of M/50, the nationwide loading (M) of cdma2000 carrier wave can exhaust the nationwide capacity of the GSM carrier wave of all 6 corresponding (with cdma2000 carrier wave frequency together).Similarly, because 25 GSM carrier waves that can exist in the bandwidth of single W-CDMA carrier occupancy are arranged, so with the same amount of L/200, the nationwide loading (L) of W-CDMA carrier wave can exhaust the nationwide capacity of the GSM carrier wave of all 25 corresponding (with W-CDMA carrier wave frequency together).Owing to similar reason, because 4 cdma2000 carrier waves that can hold (with frequently) are arranged on W-CDMA carrier occupancy frequency band, so, with the same amount of L/4, the nationwide loading of W-CDMA carrier wave can exhaust the nationwide capacity of the cdma2000 carrier wave of all 4 corresponding (with W-CDMA carrier wave frequency together).

Equation (1) and (2) can be summarized as follows:

$\underset{i=1}{\overset{x}{\mathrm{\Σ}}}\frac{N_i}{F_i}=\mathrm{MARP},---\left(3\right)$

Wherein, N_iBe to use the quantity of the same frequency active user of allocated frequency band and/or air interface i;

F_iIt is the equivalence factor (can less than, more than or equal to 1) of the correspondence of allocated frequency band/air interface i; And

MARP is measuring of the maximum set radiated power spectral density that allows.

To understand, in FCC 03-15, can may not exceed-53+10log (1725) ≈-20.6dbW/Hz in the set radiated power spectral density (PSD) of U.S. scope emission with the ATN wireless terminal in communication.For drawing this conclusion, FCC supposition ATN will be based on the GSM technology and gsm wireless terminal can be at (for example, the EIRP of the maximum (up link) of each carrier wave 0dBW of emission on direction Inmarsat) of same-frequency satellite system.The conclusion of FCC also is based on has only 50% supposition in U.S. inside among the ATN.

If allow among the ATN more than 50% in U.S. inside, the PSD that gathers radiation U.S. scope so can be higher.For example, based on 80% the expansion of total ATN of US inside, the US scope PSD current potential that set allows can increase and is-53+10log (2760) ≈-18.6dbW/Hz.In FCC 03-15, the committee concludes: the ensemble average signal attenuation relevant with uplink channel interference is 242.7dB.This value considered since (a) free space propagate (188.7dB), (b) the same frequency system satellite antenna on the ATN direction use (3.5dB) of (25dB), (c) outdoor obstruction (3.1dB), closed power control (20dB) that (d) ATN implements, (e) low rate vocoder, (f) voice activity (1dB) and (g) decay/inhibition of the interference signal that causes of the polarization discriminating (1.4dB) that provides of same-frequency satellite system be provided.(referring to FCC 03-15, appendix C 2, table 2.1.1.C, 206 pages).Because suppressing (20dB), the interference signal that power control causes comprises because 2dB that " scope awl (rangetaper) " causes and because the 18dB that structural damping causes.Based on the conclusion/supposition of the committee, as stipulating in FCC 03-15, and supposition is at inner nearly 80% the ATN that launches of US, can be restricted to-18.6-242.7=-261.3dBW/Hz at the ensemble average PSD current potential of the input of same-frequency satellite antenna.

As mentioned above, set radiant power control system according to some embodiments of the invention and method can be configured to the wireless telephonic set radiant power of multi-section is restricted to the maximum set radiant power.In the above-described embodiments, suppose that ATN has the structural damping tolerance limit and/or the return link tolerance limit of equal number on its all ancillary terrestrial components, these ancillary terrestrial components use given frequency band and/or carrier frequency and/or air interface.Under this supposition, carry out above-mentioned calculating.Yet this may be always not true.More properly, according to other embodiments of the invention, the various ATC among the ATN can provide different structural damping tolerance limit and/or return link tolerance limit.In fact, according to other embodiments of the invention, in various ATC, can increase link margin and can not exceed the maximum set radiant power with communication on the wireless terminal ground that allows bigger quantity.Two illustrative examples will be provided.In first example, a plurality of cdma2000 wireless terminals are communicated by letter with ATN foundation structure, and ATN foundation structure provides the structural damping tolerance limit of 18dB.In second example, not every ATN foundation structure all provides the structural damping tolerance limit of 18dB.

Therefore, in first example, all cdma2000ATC wireless terminals are communicated by letter with the foundation structure of the structural damping tolerance limit that 18dB is provided.About satellite, can radiation for example maximum (space average) EIRP of cdma2000ATN wireless terminal: each communication channel (that is each sign indicating number; For the sake of simplicity, ignored the EIRP that pilot channel consumes)-13dBW.Therefore, the PSD current potential of the wireless terminal of each communication channel can be-74-242.7=-316.7dBW/Hz for-74dBW/Hz (at the antenna output end of wireless terminal) and at the satellite antenna input.The quantity of this class wireless terminal (communication channel) that the PSD current potential-261.3dBW/Hz that allows for the input generation at satellite antenna operates together frequently is 10^{[(316.7-261.3)/l0]}=346,736.In certain embodiments, in ATN, can launch nearly seven (7) individual cdma2000 carrier waves.Therefore, the total air capacity based on the ATN of U.S. can be 346,736 * 7=2, the communication channel of 427,152 whiles.

In second example, not every wireless terminal is communicated by letter with the foundation structure of the structural damping tolerance limit that 18dB is provided.For example, establish the potential percentage (%) that X, Y and Z represent the US scope of ATN cdma2000 wireless terminal, these wireless terminals can be communicated by letter with frequency with the ATN foundation structure of the structural damping tolerance limit that A, B and CdB are provided respectively.Therefore:

X+Y+Z=100. (4) establish the quantity that L, M and N represent the potential wireless terminal that can communicate by letter with category-A, category-B and C class foundation structure respectively, and we can be written as:

X=100L/ (L+M+N), Y=100M/ (L+M+N), Z=100N/ (L+M+N). (5) under can condition for the ATN foundation structure (as mentioned above) of this three types/kind of ATN wireless terminal service, the set power spectrum density current potential of satellite antenna input (watt/Hz) can be:

In equation (6), 10log (σ²) numerical value can for example be defined as-74dBW/Hz, and ξ, ζ and

Can represent average set (power domain) attenuation factor related with this three classes wireless terminal respectively, this three classes wireless terminal can be served by three class foundation structures.Therefore, we can be written as:

10log(ξ)＝-(188.7+25+3.1+(A+2)+3.5+1+1.4)＝-(224.7+A)dB (7)

10log(ζ)＝-(188.7+25+3-1+(B+2)+3.5+1+1.4)＝-(224.7+B)dB；and (8)

Use equation (5):

N=L[(100-X) (100-Y-XY]/100X, and M=100YL/[(100-Y) (100-Z)-YZ]. (10) are with equation (7) to (10) substitution equatioies (6) and take the logarithm, and can be expressed as at the mean P SD of the satellite of being injured current potential:

PSD≡10log(psd)＝10log(σ²)+10log(L)

+10log(10^{-(22.47+0.1A)}+10^{-(22.47+0.1B)}×100Y/[(100-Y)(100-Z)-YZ] (11)

+ 10^{-(22.47+0.1C)}* [(100-X) (100-Y)-XY]/100X) or

-261.3＝-74+10log(L)

+10log(10^{-(22.47+0.1A)}+10^{-(22.47+0.1B)}×100Y/[(100-Y(100-Z)-YZ] (12)

+10^{-(22.47+0.1C)}×[(100-X)(100-Y)-XY]/100X).

Solve L:

L＝10^-18.73-log() (13)

In equation 13, second index " log () " determined by equation (12).Promptly

log()≡log(10^{-(22.47+0.1A)}+10^{-(22.47+0.1B)}×100Y/(100-Y)(100-Z)-YZ](14)

+10^{-(22.47+0.1C)}×[(100-X)(100-Y)-XY]/100X).

In case determine L by equation (13), can use equation (5) to determine that N and M must be worth as follows so:

N＝L[(100-X)(100-Y)-XY]/100X，and M＝Y(L+N)/(100-Y) (15)

Following table has provided illustrative numerical result:

Therefore, the second above-mentioned example can provide equation (3) additional embodiment, wherein, and N_iBe illustrated in the quantity of the shared channel of operating under the condition of public (i) structural damping tolerance limit of allocated frequency band and/or carrier frequency and/or air interface, F_iRepresent corresponding equivalence factor, public (i) structural damping tolerance limit for allocated frequency band and/or carrier frequency and/or air interface, this factor can less than, more than or equal to 1, be measuring of maximum set radiated power spectral density (PSD) and MARP is the maximum set radiant power.

In some embodiments of the invention, ATN can be configured to safeguard a row basic structural member (being base station and/or base station group) and measuring of structural damping tolerance limit (SAM) is related with each basic structural member.Based on register step and/or other means of wireless terminal, ATN also can be configured to know the basic structural member of the wireless terminal communications of each activity (launching (on-the-air)).Therefore therefore, ATN can be configured to SAM is related with each movable portable terminal and can be configured to determine ∑_i(psd)_iValue, wherein, psd be illustrated in satellite power spectral density and can be the suing for peace on the whole of the wireless terminal of movable (in the air), these wireless terminals in ATN with operating (that is, shared ATN frequency band and/or sub-band is all or part of) frequently.In some embodiments of the invention, individual for i with the frequency wireless terminal, can determine numerical value (psd)_iValue be:

${\left(\mathrm{psd}\right)}_i={10}^{[\log (p_i/B{W}_i)+\log \left({\mathrm{\α}}_i\right)]},---\left(16\right)$

Wherein, numerical value 10log (p_i) can be illustrated in measuring of maximum EIRP on the satellite direction, this maximum EIRP can by the wireless terminal generation of i movable (in the air) (for example, for GSM be-4dBW, for cdma2000 and/or W-CDMA be-13dBW).BW_iThe measuring of bandwidth (for example, be 200KHz, be 1.25MHz and/or be 5MHz) that can represent the carrier occupancy of i active terminal radiation, and 10log (α for W-CDMA for cdma2000 for GSM_i) can represent to be present in measuring of aggregate signal decay between i wireless terminal and the satellite.

Numerical value 10log (α_i) can be expressed as 10log (α in addition_i(the L+SAM of)=-_i) dB, wherein, L is defined as measuring of aggregate signal decay current potential, comprise that for example (a) free space propagates that (being 188.7dB), (b) same-frequency satellite antenna are differentiated (being 25dB), (c) outdoor obstruction (being 3.1dB), (d) because effect (being 1dB) of the effect (being 3.5dB) of the ATN power control (being 2dB) that the scope awl causes, (e) low rate vocoder, (f) voice activity and (g) the polarization discriminating (being 1.4dB) that provides of same-frequency satellite antenna.(referring to FCC03-15appendix C 2, table 2.1.1.C; 206 pages).SAM_iCan represent measuring of structural damping tolerance limit that basic structural member (being base station and/or base station group) provides, i movable communicates by letter with this basic structural member with frequency terminal.SAM_iRepresentative value can be for example to be respectively applied for 22dB, 18dB, 12dB and the 6dB of dense city, city, sub-city and rural basic structural member.

Therefore, in some embodiments of the invention, set radiant power controller is configured to control a plurality of with wireless terminals frequently, the set radiant power of a plurality of wireless terminals is restricted to the maximum set radiant power according to following formula:

$\underset{i=1}{\overset{x}{\mathrm{\Σ}}}{\left(\mathrm{psd}\right)}_i=\mathrm{MARP},---\left(7\right)$

Wherein (psd)_iBe the measuring of radiated power spectral density of satellite and MARP is measuring of the maximum set radiant power that allows.Basis in certain embodiments, psd be according to${\left(\mathrm{psd}\right)}_i={10}^{[\log (p_i/B{W}_i)+\log \left({\mathrm{\α}}_i\right)]}$Determine; Wherein, 10log (p_i) expression measures BW by the maximum radiated power of i wireless terminal on satellite direction_iThe bandwidth of representing the carrier occupancy of i wireless terminal radiation, and 10log (α_i) the measuring of signal attenuation (dB) between i wireless terminal of expression and the satellite.

ATN can determine the numerical value ∑_i(psd)_iValue and/or its another measure (if required), and can be in response to ∑ approaching, that equal or exceed threshold value_i(psd)_iValue and/or its another measure and control ancillary terrestrial network and/or one or more wireless terminal is restricted to the maximum set radiant power will gather radiant power.

Many technology can be used for the limitations set radiant power.For example, in certain embodiments, one or morely can be come 1 by order with wireless terminals frequently) utilize low rate vocoder and/or 2) reduce the rate of information throughput and/or 3) and use other available may not be with about the numerical value ∑_i(psd)_i(frequency that does not promptly surpass the maximum set radiant power) and/or its another resource of measuring are with ATN or non-ATN resource frequently.Therefore, in certain embodiments, set radiant power controller is configured to use the frequency for communication that does not exceed the maximum set radiant power to control a plurality of wireless terminals by the vocoder rate that reduces at least one wireless terminal and/or the rate of information throughput by being reduced by at least a wireless terminal and/or by controlling at least one wireless terminal, so that a plurality of set radiant powers with the frequency wireless terminals are restricted to the maximum set radiant power.
