Embodiment

Preferred embodiment a kind of, for the local number of finishing realization of the present invention is rented, corresponding to technical scheme of the present invention, new equipment---number is rented control appliance to take to increase by one in existing mobile communication network system, number rent control appliance can one one of local network, also can share one by a plurality of local networks.Number is rented the responsible management to the mobile roaming user of control appliance, and when the mobile subscriber was not in roaming state, all signalings were all rented control appliance without number.According to technical scheme of the present invention, number is rented control appliance for different network entities, role's difference of being served as, for the roamer, it is exactly HLR and MC (the Message Center that the user opens an account, be message center), it is exactly the MSC/VLR of the roaming place visited of user for HLR that the user opened an account and MC.Number is rented the repertoire that control appliance has HLR, also have MSC/VLR (Mobile Switch Center, mobile switching centre/Visit Location Register, VLR Visitor Location Register), the partial function of MC, also needing can double as Signalling Transfer Point (STP, i.e. Signaling Transfer Point).Number is rented distribution and the withdrawal that control appliance also is responsible for local number, and certain number assignment mechanism is arranged.

In the present embodiment, the implementation method of local number leased service may further comprise the steps:

A) authorize to adopt the mobile subscriber of local number leased service need to use separately in the one or more specific IMSI section among its ownership HLR a certain IMSI number, described specific IMSI section is exactly to be used for carrying out the local number leased service specially, the user is set to unique IMSI number in the HLR of ownership, with common user's the information of opening an account unanimity.

B) in existing network, increase number and rent control appliance, number is rented control appliance and is being managed the information of opening an account (mainly being authentication information) that all authorize the user of local number leased service, is used for number and rents control appliance to using this professional user's authentication process;

C) the one or more local MDN sections of control appliance need number assigned be rented in the area of opening the local number leased service, rent control appliance for number and distribute to this professional mobile subscriber of use.Be about to these numbers rents to the mobile subscriber who roams into this area temporarily.Number is rented some MDN section that control appliance can be deposited a plurality of areas, by being shared in a plurality of areas.Number is rented control appliance roamer service.

D) when the mobile subscriber does not roam, when carrying out the position renewal in this locality, MSC/VLR to the locality initiates position updating request, local MSC/VLR analyzes the HLR address of this user attaching according to the IMSI in the request, initiating the position to ownership HLR upgrades, this flow process is the same with existing mobile communication technology, not change.When carrying out when the user roams that the first time, the position was upgraded, MSC/VLR to the roaming place initiates position updating request, the MSC/VLR of roaming place analyzes the address that number is rented control appliance according to IMSI in the request, rent control appliance to number and initiate position updating request, number is rented the HLR of this signaling of the transparent transmission of control appliance to user attaching.Number is rented control appliance and is learnt that the user is registration for the first time, just sends SMS message to the user and points out the user to use the local number leased service.

E) user activates this leased service by dialing condition code, rent control appliance by number and notify the user new number by the mode of short message, perhaps the user dials a specific Number for access and activates this business, and system notifies the user new number by the method for recorded announcement.

F) number is rented control appliance and is initiatively sent the qualification indicator to the MSC/VLR that the user registered, and the MDN number that order MSC/VLR changes the user is new MDN number.Be that what write down among the MSC/VLR is the new MDN number of user.

G) number is rented control appliance and is initiatively initiated the position renewal to the HLR of user attaching, user position information is changed to the address that number is rented control appliance, the HLR of ownership rents the control appliance home position to number and upgrades response, and number is rented the CAMEL-Subscription-Information of control appliance recording user.Later user's information changes all rents the control appliance record by number, the HLR of user and ownership has not then got in touch, the user position information that writes down among the HLR of ownership is exactly the address that number is rented control appliance, promptly for the HLR of ownership, the role that number is rented control appliance is equivalent to the MSC/VLR of roaming place.When the user roamed into other areas, number was rented control appliance and is just regained the MDN number that distributes into the user, points out the user to activate the number leased service again again, rents the number in new area.

I) when getting back to ownership place, the user carries out the position again when upgrading, the local number leased service deactivates automatically, because the positional information of ownership place HLR recording user is the address that number is rented control appliance, so the HLR of ownership can require number to rent control appliance and deactivate this user, number is rented control appliance just recoverable MDN number for this user's distribution this moment, and the MSC/VLR of notice roaming place deletes this user.The user has recovered original MDN number again.

Further, above-mentioned mobile subscriber rents the method for local number, one of them mobile communication user is assigned with a local number, this local number can shield the user, the user can still use original number, the charge number that is the user separates with external numbers displayed, and to be visit ground MSC/VLR the user rise separation method rents control appliance with number when exhaling and carry out Signalling exchange, rents control appliance by number and external numbers displayed is changed etc.When other people dial this user's original number, because for the HLR of ownership, user position information is the address that number is rented control appliance, is responsible for obtaining routing iinformation so rent control appliance by number, so also can be got through.

Below in conjunction with accompanying drawing, further specify the specific embodiment of the present invention.

According to the prior protocols standard, can adopt in network increases that number is rented control appliance or the existing HLR system that upgrades realizes this business.No matter take which kind of mode, the required function of finishing is identical.Now just rent the mode of control appliance and describe its implementation in detail in conjunction with Fig. 1 by in network, increasing number.Fig. 1 is the schematic network structure that realizes that local number of the present invention is rented, and wherein the lines part only represents that signaling connects, and dotted line represents that optional signaling connects, and heavy black line represents that the signaling that increases newly connects.

Opened the local number leased service such as local network 1, then the position of newly added equipment in network as shown in Figure 1, if wherein the HLR/AUC of local network 1 possesses the function of Signalling Transfer Point, then HLR/AUC can transfer and go to the part signaling that number is rented control appliance, i.e. black thick dashed line part among the figure; If do not possess the function of Signalling Transfer Point then carry out signal switching by the STP point, directly signaling to be issued number by STP and rent control appliance, number is rented and is transferred by STP after control appliance is handled signaling again.MSC/VLR rents with number can have signaling to connect between the control appliance.Below description do not have the function of Signalling Transfer Point based on the HLR/AUC in the local network 1, promptly the black thick dashed line among Fig. 1 does not exist.

In the present invention, when the user when HLR opens an account, HLR distributes specific number section ground IMSI number for the user, the user who has the IMSI number of this specific number section just can become the authorized user of local number leased service.When the trans-regional roaming of this user, need not change the SIM/UIM card like this, and just can use the local number resource by the mode of renting by above-mentioned steps.

Said method is applicable to multiple mobile communications network, includes but not limited to GSM (Global Systemfor Mobile communications global mobile communication) network and CDMA (Code DivisionMultiple Access code division multiple access) network etc.

Below adopt the concrete application example of technical scheme provided by the invention for the mobile subscriber who authorizes the local number leased service, suppose to authorize an X ground (the present invention the is assumed to be Nanjing) user of local number leased service to roam into Beijing, rent the local number of Y ground (the present invention is assumed to be Beijing), concrete service implementation is as follows:

1) opens an account

According to user's requirement, the HLR of ownership distributes the IMSI number of a specific number section for the user in database.And user's authentication information is notified to number rents control appliance.User's mobile number, and other subscription data only preserve by the HLR of ownership.Number is rented the authentication information that control appliance has write down the user like this, and the user profile of the HLR record of ownership is consistent with other users, does not do extra processing.

2) activation of service (with reference to Fig. 2):

1. the user roams into Beijing, and number is rented control and established and detect the user and roamed into the MSC/VLR of Pekinese, just sends SMS message to the user, and prompting allows it activate local number leased service, i.e. execution in step 201 actions.

2 users finish professional activation by dialing condition code or access code, and number is rented control and is made as the user and distributes a local number.And inform that the MSC/VLR that user and Ta register, later user just use the MDN of this number as oneself, the user's who preserves among the MSC/VLR that he registered MDN number also is this new number, i.e. execution in step 202 actions.

3. number is rented the HLR/AUC that the control appliance structure registration message location information notification that the user is new is given Nanjing, wherein this new positional information is the address that number is rented control appliance, the user position information of the HLR/AUC in Nanjing preservation later on is exactly the address that number is rented control appliance, i.e. execution in step 203 actions.

4. user's local number leased service activates, and operations such as later user's registration authentication are rented control appliance by number and finished, and has not then got in touch with the Nanjing HLR/AUC that belongs to, and promptly the user becomes interim local user.

3) professional deactivation (referring to Fig. 3):

1. the user gets back to ownership place Nanjing, and the MSC/VLR in Nanjing initiates registration message and rents control appliance transmission registration cancellation message according to the user position information of record to number to the Nanjing HLR that belongs to, and promptlystep 302 is moved.

2. number is rented control appliance and is regained the user's use for other of the interim local number that distributes for this user;

3. number is rented control appliance and is sent registration cancellation message to the MSC/VLR of Pekinese, and the MSC/VLR of Pekinese deletes this user, i.e. execution instep 301 actions.

4. the MSC/VLR of user in Nanjing registers successfully, user's local number leased service deexcitation.

4) professional use (referring to Fig. 4)---the user roams into Beijing and initiates registration:

1. the MSC/VLR of Pekinese sends the Nanjing HLR of registration message to its ownership, because with user's IMSI as purpose GT (Global Title, be global title), so signaling is at first rented control appliance through number, number is rented control appliance and is judged whether the user has activated the local number leased service, if activate, then number is rented the effect that control appliance is equivalent to HLR, handle this signaling, i.e. execution instep 401 actions;

2. if the local number leased service does not activate, then number is rented the effect that control appliance is equivalent to Signalling Transfer Point, and this message of transparent transmission is to the HLR/AUC in Nanjing, and promptly execution instep 402 is moved.

5) work the process of exhaling:

The user is owing to successfully login at local MSC/VLR, and the data that have the user to contract rise and exhale that to rent control appliance irrelevant with number.Because what register in VLR is local number, therefore, working what use when exhaling is local number.Further, also can the user rise when exhaling and number is rented control appliance and carried out some Signalling exchange and rent control appliance by number and external numbers displayed is changed etc.

6) called routing procedure:

According to the number difference that the user dialed, two kinds of situations can be arranged:

First kind of situation: the user uses original number, GMSC/MSC is to the HLR request user's of user attaching routing iinformation, because the user position information of the HLR of user attaching record is the address that number is rented control appliance, so the HLR of ownership rents the control appliance request route information to number, number is rented control appliance the MDN number in the signaling is replaced with new MDN number, to the MSC/VLR of user visiting request route information, the routing iinformation that number is rented the user that control appliance will obtain from MSC/VLR returns to HLR, HLR returns to GMSC/MSC with this information, and GMSC/MSC is established to the calling of the MSC/VLR on user visiting ground.

Second kind of situation: the user uses new MDN number, and GMSC/MSC rents control appliance request user's routing iinformation to number, and this moment, number was rented the role that control appliance is served as HLR, finished obtaining of route.

7) short message original calling:

Under existing charging system, the short message the when user roams charges with not roaming, still uses former MDN number to carry out the transmitting-receiving of short message so rent the user of local number.Such as, the user sends SMS message, and as follows to the signaling of the MC of user attaching: MSC/VLR → number is rented control appliance → MC.For MSC/VLR, number is rented control appliance and is equivalent to short message service center, and signaling arrives number and rents control appliance, and number is rented control appliance calling subscriber's MDN is replaced with the MC that original number is transmitted to signaling user attaching again.Certainly, if the user also can use new MDN number to carry out the transmitting-receiving of short message, just do not need the process of FH-number transform.

8) SMS terminal call:

The signaling process that the user receives short message is: MC → number is rented control appliance → MSC/VLR.MC is to the HLR request user's of user attaching short message address information, the address information that HLR returns is the address that number is rented control appliance, signaling arrives number rent control appliance after, number is rented control appliance and the number of the former MDN of user is replaced with new MDN number is handed down to MSC/VLR.In the transmitting-receiving process of short message, it is that relay has been done in the transmission of signaling that number is rented control appliance.

Although disclosed relate in the mobile communication, realized that the method that local number is rented carried out special description with reference to embodiment, those skilled in the art can understand, under the situation that does not depart from scope and spirit of the present invention, can carry out all conspicuous modification of form and details to it.Therefore, embodiment described above is illustrative and not restrictive, and under the situation that does not break away from the spirit and scope of the present invention, all variations and modification are all within the scope of the present invention.
