Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the invention is described.
For convenience of description, all (GlobalSystem For Mobile Communication, GSM) example that is applied as in describes embodiments of the invention in global system for mobile communications with it.Yet, other communication systems in the wireless telecommunications, as broadband CDMA system (Wide Code DivisionMultiple Access, WCDMA), CDMA 2000 (Code Division Multiple Access, CDMA2000), (Time Division-Synchronous CodeDivision Multiple Access TD-SCDMA) all can support the single-base band single-radio frequency dual-SIM dual-standby communication terminal of the present invention and the means of communication to TDS-CDMA system.
Figure 1 shows that embodiment of the invention single-base band single-radio frequency dual-SIM dual-standby communication terminal structure schematic diagram.A kind of single-base band single-radio frequency dual-SIM dual-standby communication terminal of the embodiment of the invention comprisescommunication module 105, selects module 107 and judge module 109.Communication module 105 is used to obtain the network schemer information of first card, 101 andsecond card 103, the operator information of this network schemer information representationfirst card 101 and second card 103.Judge module 109 is used to judge whether the operator information offirst card 101 that thiscommunication module 105 obtains andsecond card 103 is identical.Selection module 107 is used for the judgement according to thisjudge module 10, selects network information receive mode.
In an embodiment, network schemer information can be the operator information of first card, 101 andsecond card 103, and perhaps some field in this network schemer information is represented the operator information of first card, 101 and second card 103.Underfirst card 101 and the identical situation ofsecond card 103 operators, this network schemer information can further include the information of the accompanying base station of thisfirst card 101 andsecond card 103.
In an embodiment, the network information can be BCCH information and/or PCH information.
As shown in Figure 1, communicatingterminal 10 comprises first card, 101 and second card 103.First card, 101 andsecond card 103 can be the communicating terminal card under the same operator, also can be the communicating terminal card of different operators or different communication networks.
In gsm communication system,, only need in every frame, receive a time slot usually to obtain logical channel information for each physical channel.For BCCH and PCH channel, agreement is defined under the ideal case, and communicatingterminal 10 needs to receive two information on the channel in the fixed cycle.Therefore, in the dual-card dual-standby communication system of single base band injection frequency scheme, three kinds of situations may appear in the network schemer combination of first card, 101 and second card 103:
A. two cards belong to same operator, and are attached on the same base;
B. two cards belong to same operator, but are attached on the different base station;
C. two cards belong to different operators, are attached on the different base station.
In an embodiment,judge module 109 is used to judge whether the operator of this first card, 101 andsecond card 103 is same operator.Usually,judge module 109 can obtain the operator's informaiton of this first card, 101 andsecond card 103 by the information that reads first card, 101 andsecond card 103 when communicatingterminal 10 starting up.When the operator of judging this first card, 101 andsecond card 103 was same operator, thisjudge module 109 was further used for judging whether the base station of adhering to of first card, 101 andsecond card 103 is same base.
Judging the operator information of first card, 101 andsecond card 103 when judgemodule 109 is same operator information and first card, 101 andsecond card 103 when adhering to same base, selects module 107 to be used to select to receive at identical or different time slot by first card, 101 andsecond card 103 receive modes of the network information.When judgemodule 109 judged that the operator information of first card, 101 andsecond card 103 is same operator information,judge module 109 judged further whether the base station of adhering to of first card, 101 andsecond card 103 is same base.When the adhering to the base station and be same base of first card, 101 andsecond card 103, select module 107 to select first network information receive mode.Under first network information receive mode,communication module 105 can receive the BCCH information and/or the PCH information of first card, 101 andsecond card 103 simultaneously at identical time slot, also can receive the BCCH information offirst card 101 and/or BCCH information and/or the PCH information that PCH information receivessecond card 103 more earlier.
Judging the operator information of first card, 101 andsecond card 103 whenjudge module 109 is same operator information and first card, 101 andsecond card 103 when adhering to different base station, selects module 107 to be used to select to receive at different time-gap by first card, 101 andsecond card 103 receive modes of the network information.When the adhering to the base station and be different base station of first card, 101 andsecond card 103, select module 107 to select second network information receive mode.Under second network information receive mode,communication module 105 receives the BCCH information offirst card 101 and/or BCCH information and/or the PCH information that PCH information receivessecond card 103 more earlier.
Select module 107 to be further used for when judgemodule 109 judges that the operator of first card, 101 andsecond card 103 is different operators, selecting to receive at different time-gap the receive mode of the network information by first card, 101 and second card 103.When judgemodule 109 judges that the operator information of first card, 101 andsecond card 103 is different operators information, select module 107 to select second network information receive mode.When the operator of first card, 101 andsecond card 103 is different operators,communication module 105 can be used for receiving the network information by two different time-gaps that are stuck in the identical frame of burst sequence number, also can be used for receiving the network information at the different time-gap of the different frame of burst sequence number.
Be illustrated in figure 2 as the means of communication flow chart of embodiment of the invention single-base band single-radio frequency dual-SIM dual-standby communication terminal.As shown in the figure, this method comprises S301, obtains the first network schemer information of blocking 101 andsecond card 103 in the present embodiment, operator information of this first card, 101 andsecond card 103 of described network schemer information representation; S303, judge whether thisfirst card 101 is identical with second card, 103 operator information; And S305, according to judged result, select network information receive mode.
In an embodiment, network schemer information can be the operator information of first card, 101 andsecond card 103, and perhaps some field in this network schemer information is represented the operator information of first card, 101 and second card 103.Underfirst card 101 and the identical situation ofsecond card 103 operators, this network schemer information can further include the information of the accompanying base station of thisfirst card 101 andsecond card 103.
In an embodiment, the network information can be BCCH information and/or PCH information.
As previously mentioned, in the dual-card dual-standby communication system of single base band injection frequency scheme, three kinds of situations may appear in the network schemer combination of first card, 101 and second card 103.If the BCCH and the PCH of two calorie requirement receptions do not conflict in time, promptly when harvesting whole BCCH/PCH message, a clamping need not receive the BCCH/PCH of an other card, and use this moment mechanism commonly used to get final product; Otherwise can think that BCCH and PCH that two clampings are received conflict in time.
In an embodiment, communicatingterminal 10 has different receiving modes according to the combination of twocards.Judge module 109 obtains the operator information of first card, 101 andsecond card 103, and judges whether the operator of first card, 101 andsecond card 103 is same operator.
Whenjudge module 109 judged that the operator of first card, 101 andsecond card 103 is same operator, judgemodule 109 judged further whetherfirst card 101 andsecond card 103 adhere to the base station identical.When first card, 101 andsecond card 103 adheres to same base, select module 107 to select first network information receive mode, receive the network information by first card, 101 andsecond card 103 at identical or different time slot bycommunication module 105.
As shown in Figure 3, first card, 101 andsecond card 103 belongs to same operator and is attached on the same base station.The Common Control Channel group (Common Control Channel Group, CCCH GROUP) that judge module 107 is done behind the location area updating according to two cards judges how to receive.In the embodiment shown in fig. 3, the reception of first card, 101 andsecond card 103 is divided into following four kinds of situations.Need to prove that because first card, 101 andsecond card 103 belongs to same operator and is attached to same base station, thereforesecond card 103 can no longer receive the BCCH channel information.
A. first card, 101 andsecond card 103 all receives on 0 time slot;
B.first card 101 receives on 0 time slot, andsecond card 103 receives on 2 time slots;
C.first card 101 receives on 0 time slot, andsecond card 103 receives on 4 time slots;
D.first card 101 receives on 0 time slot, andsecond card 103 receives on 6 time slots.
Whenjudge module 109 judged that the operator of first card, 101 andsecond card 103 is same operator, judgemodule 109 judged further whetherfirst card 101 andsecond card 103 adhere to the base station identical.When first card, 101 andsecond card 103 adheres to different base station, select module 107 to select second network information receive mode, be stuck in different time-gap bycommunication module 105 by first card and second and receive the network information.When judgemodule 109 judges that the operator of first card, 101 andsecond card 103 is different operators, select module 107 also to select second network information receive mode, be stuck in different time-gap bycommunication module 105 by first card and second and receive the network information.When the operator of first card, 101 andsecond card 103 is different operators,communication module 105 can receive the network information by two different time-gaps that are stuck in the identical frame of burst sequence number, also can receive the network information at the different time-gap of the different frame of burst sequence number.
As shown in Figure 4, under second network information receive mode, first card, 101 andsecond card 103 receives the BCCH and the PCH of different frequent points respectively.Among the embodiment as shown in Figure 4, the receiving slot of the BCCH/PCH ofsecond card 103 is in the frame time thatfirst card 101 receives, and the burst sequence number of the BCCH/PCH of two cards in a frame time is identical.Only receiving this moment to arrange the reception of two time slots to get final product in a frame.Should be noted that also that simultaneously the 0 time slot reception ofsecond card 103 can't necessarily be alignd with certain time slot time started offirst card 101 at this moment, this needs baseband chip to control flexibly.
Figure 5 shows that another embodiment time slot distribution map of second network information receivemode.Block 101 burst sequence number not in same frame time with first when in an embodiment,second card 103 receives BCCH or PCH.The 1st burst whensecond card 103 receives BCCH or PCH is in the 2nd burst frame time of first card 101.And the like the 1st bursts thatsecond card 103 receives also may appear in the 3rd offirst card 101 or the 4th burst frame time.Need baseband chip to control flexibly for this situation and guarantee correctly to receive, before carrying out deinterleaving, reconstruct initial data simultaneously according to the burst sequence number at each burst.
Figure 6 shows that first card, 101 andsecond card 103 receives BCGH or PCH is overlapping on physical slot by time top.In this case, need abandon the reception of a certain card usually.But, when signal is enough strong, can directly obtain BCCH or PCH message by receiving two bursts because BCCH and PCH include the error correction bit of 40 bit.Therefore, in this case, base band can arrange front cross frame to receive the BCCH or the PCH offirst card 101, and back two frame arrangements receive the BCCH or the PCH ofsecond card 103.
In sum, in embodiments of the present invention,, can solve that BCCH are received in two clampings and PCH receives conflict situations, guarantee at the appointed time reception BCCH and PCH message no matter be same operator or different operators.The embodiment of the invention can make the terminal called success rate of single-base band single-radio frequency dual-SIM dual-standby communication improve greatly, has reduced the generation of falling the net phenomenon simultaneously greatly.
Be understandable that, for those of ordinary skills, can be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, and all these changes or replacement all should belong to the protection range of the appended claim of the present invention.
