Description

A kind of method and device that upgrades user terminal switch-in code

Technical field

The present invention relates to the cross-domain call technology, refer to that especially user terminal (UE) is under the roaming state, a kind of method and device that upgrades user terminal switch-in code.

Background technology

From third generation affiliate version 5 (3GPP R5), the core net of universal mobile telecommunications system (UMTS) just is divided into three subsystems: circuit switching (CS), packet switching (PS) and IP Multimedia System (IMS).Wherein, CS territory (Circuit Switched Domain) is used for providing to the user connection of Circuit Service, comprise mobile switching centre (MSC), GMSC, the several main entities of interoperability function (IWF) module, MSC (MSC Server/CS-MGW) is used to finish the exchange and the signaling controlled function of circuit switched type business; GMSC is the MSC that finishes mobile subscriber's routing addressing function in a certain network, can close with MSC if set up separately; General and the MSC of IWF is closely related, be used to finish the intercommunication between Public Land Mobile Network (PLMN) and Integrated Service Digital Network, public switched telecommunication network (PSTN), the Packet Data Network (PDN), mainly finish the signaling translation function, concrete function is according to professional stipulate different with the network kind.

PS territory (Packet Switched Domain) is used for providing to the user connection of packet-type business, comprise: GPRS Support Node (GSN) and borde gateway (BG) two class entities, wherein, GSN is used to finish the transmission of Packet Service user grouping bag, GSN comprises Serving GPRS Support Node (SGSN) and Gateway GPRS Support Node (GGSN) again, SGSN provides BSS in core net and the wireless access system, the connection of RNS, finish the mobile management of multicomponent data business, functions such as session management, management travelling carriage (MS) moving and communication service in the mobile network; GGSN also has the function of inquiring position information simultaneously as the interface between mobile communication system and other public data network, and SGSN, GGSN all can provide charge information.BG is used to finish the intercommunication between two GPRS network, guarantees the fail safe of network interworking.

In addition, CS territory and PS territory also shared following functional entity: HLR/AuC, attaching position register (HLR) is used to finish the management of user contracting data and positional information, wherein, user contracting data comprises MSISDN, IMSI, PDP ADDRESS, signatory telecommunication service and supplementary service and professional scope of application thereof or the like, and positional information comprises MSRN, MSC/VLR number, SGSN number, GMLC or the like; Authentication center (AuC) then is used to store user's authentication arithmetic and key.VLR Visitor Location Register (VLR) is used to handle the various data messages of visitor; EIR is used to store customer equipment identification (IMEI) information; Also has Gateway Short Message Center MSC (SMS-GMSC/SMS IMSC) or the like.

IMS (IP Multimedia Subsystem) is a subsystem that is superimposed upon in the WCDMA network that increases in the 3GPP R5 stage on the existing packet domain, adopt the bearer path of packet domain for its upper strata control signaling and media delivery, introduce initial session protocol (SIP) as professional control protocol, utilize simple, the easy expansion of SIP, media combination characteristics easily, by business control is separated with carrying control, provide abundant multimedia service.Among the IMS main functional entity comprise functions such as control user registration, session control call conversation control function entity (CSCF), provide miscellaneous service logic control function application server (AS), manage the home subscriber server (HSS) of user contracting data concentratedly and be used to realize MGCF/IP multimedia-medium gateway function (MGCF/IM-MGW) with the circuit switching net interconnecting.The user inserts IMS by current on-site proxy CSCF (P-CSCF), and session and professional triggering are controlled and be mutual with the business control of AS, are then finished by the home domain serving CSCF (S-CSCF) of user registered place.Wherein, the HSS among the IMS is the superset of HLR, the compatible HLR of energy on the function, but in concrete networking, the HLR of HSS and CS/PS generally sets up separately.

Solved the roam charge that the required solution of multimedia service is provided under the IP carrying by the defined IMS framework of 3GPP standard comprehensively, QoS, but the problems of operation that safety guarantee etc. are crucial, its framework and thinking have obtained industry and have generally acknowledged, 3GPP2, TISPAN has all carried out the definition of corresponding IP multi-media network framework and business system with the 3GPP model as basis and reference, 3GPP has also begun to insert and UMTS intercommunication (I-WLAN) at WLAN, fixed broadband inserts IMS (FBI) and towards the all-IP net important function for of research such as (AIPN) of multiple access technology, make the user can be according to the CAMEL-Subscription-Information of self, insert IMS by single multimode terminal or the different terminal of polytype via the access network that adopts different access technologies, to obtain the unified multimedia service that comprises the VoIP business.In at subject study process by different access networks access IMS, proposed relevant CS call out with the VoIP business that provides by WLAN access IMS between business continuance (VCC, Voice Call Continuity) problem, and then proposed to solve the problem that the CS/IMS inter-domain routing is selected when called the user, adapting to the demand of network and business development.

At present, can in calling out, CS switch to IMS in order to make UE, current handover scheme regulation: when UE is in the CS calling, its control section is resided in IMS; In addition, when UE in calling procedure when IMS switches to the CS territory, need switch thereby carry out by the public service identities (CCCF PSI) of the CS part call continuity controlled function of UE.

For CS initial call situation, when initiating CS, CS-IMS user sets up, and need be routed to the CCCF of user's ownership IMS, thereby trigger route back-to-back user agent (B2BUA) function on the CCCF, control the load plane that this CS calls out.For the realization of this purpose, existing following several implementations:

The CS of scheme one: UE partly sends setup requests by setting up (Setup) message to Visited Mobile Switching Center (VMSC), VMSC strengthens customize services logic (CAMEL) CAMEL-Subscription-Information according to the user mobile network, trigger Initial DP message to gsm service control function (gsmSCF) entity with network domains selection function (NeDS), NeDS issues an IMS routing number (IMRN) that points to the CCCF among the IMS by CAMEL connect message to VMSC, carry CCCF PSI information among the IMRN, VMSC will call out the MGCF that routes to the IMS territory by initial address (IAM) message according to the CCCF PSI that receives, MGCF is sent to CCCF according to the described IMRN that carries in the IAM message with calling, thereby activate CS initial static anchor point business among the CCCF, this moment, CCCF was as the static anchor calling grappling of naming a person for a particular job, be that no matter the switching in CS territory to IMS territory or the switching in IMS territory to CS territory take place follow-up calling subscriber, all hand-off process carried out in the calling of grappling by this static state anchor point.

Scheme two: UE is converted to the E.164 call number of number format with the PSI of the sensing IMS AS CCCF that self preserves, and sends setup requests to VMSC, thereby routes the call to the CCCF that is arranged in AS.Use unstructured supplementary service data (USSD) mechanism simultaneously, with real called party side's number, called party subaddress, and any other need finish the information of calling out the callee and send to CCCF among the AS, triggers CS initial static anchor point business among the AS.

Scheme three: UE is converted to the E.164 call number of number format with the PSI of the sensing IMS AS CCCF that self preserves, and sends setup requests to VMSC, thereby routes the call to the CCCF that is arranged in AS.Use SIP notice (Notify) mechanism simultaneously, with real called party side's number, called party subaddress, and any other need finish the information of calling out the callee and send to CCCF among the AS, triggers CS initial static anchor point business among the AS.

The prefix number that scheme four: UE use self inside has configured cooperates the called party information parameter, forms called number, sends setup requests to VMSC.VMSC carries out number analysis according to these numbers, thereby routes the call to the CCCF that is arranged in AS, triggers CS initial static anchor point business among the AS.Need to prove: the prefix number that UE uses self inside to configure, this prefix number and above-mentioned AS PSI or E.164 number have corresponding relation.

In addition, switch to the situation in CS territory from IMS for UE in calling procedure, the CS part of UE sends setup requests according to the normal call flow process to VMSC, and the called number that carries in the setup requests is the E.164 number of AS PSI correspondence, wherein, CCCF is arranged in the AS of IMS.After VMSC receives this call request,, route the call to the CCCF among the AS of user attaching IMS network, thereby carry out corresponding handoff procedure according to this number E.164.

Need to prove: above-mentioned PSI is exactly the PSI of AS, hereinafter referred to as AS PSI.In addition, the corresponding AS PSI of number E.164, E.164 number or AS PSI that different MSC/VLR is corresponding different, hereinafter E.164 number or AS PSI are called access code, and the access code relevant with UE is called the UE access code.

From such scheme as seen, E.164 UE uses number format to call out to MSC/VLR in the prior art in the CS territory, when being in roaming condition for UE, according to each country or from different places, VMSC may adopt different access codes, such as for fire alarm, in China is 119, in the U.S. may be 911, and in the time of when UE roaming and in attached to VMSC, the access code that must use local VMSC to discern inserts required business; It is pre-configured that the access code that is used to carry out route analysis among the VMSC is based on local numbering and route planning, and can't dynamically adjust in real time, these data are the information that operator grasps, and in the scheme that existing solution UE switches between CS territory and IMS, mechanism less than the UE access code that upgrades in time according to the UE position, like this, occur possibly because access code and the access code among the VMSC among the UE are inconsistent, cause VMSC can not discern the employed access code of UE, as E.164 number or AS PSI, thereby can not carry out the problem of correct route for session, UE switches to IMS in CS calls out failure occur.

Summary of the invention

Embodiment

Core concept of the present invention is: set in advance the heavy allocation logic module that is used to realize the distribution of UE access code weight, heavy allocation logic module is redistributed the UE access code according to the UE positional information of obtaining, and the UE access code of redistributing is sent to call out carries out point, call out and carry out point and upgrade according to a UE access code that receives.This method also further sets in advance the heavily distribution judge module that is used to judge whether heavily to distribute the UE access code, after heavily distributing the judge module judgement heavily to distribute the UE access code, the UE current location information is sent to heavy allocation logic module.

Fig. 1 is the flow chart that the present invention upgrades the UE access code, suppose be used for realizing that UE inserts heavy allocation logic module that code weight distributes and presets the corresponding relation with the UE access code different MS C/VLR number, and roaming takes place in UE and under the unaltered situation of AS, the inventive method mainly may further comprise the steps:

Step 100: heavy allocation logic module is obtained the UE positional information.

The UE positional information if VMSC number changes, illustrates then that the UE position changes and the affiliated MSC/VLR of UE changes generally by VMSC number decision.Different MS C/VLR adopts and to identify for different MSC/VLR number, when MSC/VLR is in visit ground, MSC/VLR can be called VMSC.

Stipulate according to agreement, after the UE position changes, with trigger position renewal process: UE current under MSC/VLR can to HLR initiate to carry UE current under MSC/VLR number the position updating request of MSC/VLR, and whether successful HLR upgrade in the position of returning MSC/VLR and can carry indicating positions in the response and upgrade renewal indication information, if described renewal indication information display position upgrades successfully, then MSC/VLR is carried at the position through SGSN with self Temporary Mobile Subscriber Identity (TMSI) and upgrades and accept to send in the message UE, like this, UE can be by the MSC/VLR access network of the TMSI correspondence that receives.The specific implementation of position updating process can no longer repeat here referring to related protocol.

Based on above-mentioned existing position updating process, the method that the heavy allocation logic module of the present invention is obtained the UE positional information roughly is divided into:

Method one: the heavily distribution judge module that is used to judge whether heavily to distribute the UE access code, from response message is upgraded in the position, obtain indicating positions and upgrade whether successful renewal indication information, if described renewal indication information display update success, then heavily distribute judge module to judge that the affiliated MSC/VLR of UE changes, and the MSC/VLR that will obtain from location update request message number send to described heavy allocation logic module.

Method two: UE receive the position upgrade accept message after, the change in location sign that the current affiliated MSC/VLR of expression UE has changed is set, and the change in location that sets sign sent to heavily distribute judge module, afterwards, heavily distribute judge module can from HLR obtain UE current under MSC/VLR number of MSC/VLR, and MSC/VLR number of obtaining sent to described heavy allocation logic module.

Method three: when UE need set up calling, heavily distribute judge module can from initial Initial DP message, obtain UE current under MSC/VLR number of MSC/VLR, and judge this MSC/VLR number with self the storage MSC/VLR number inconsistent after, MSC/VLR number of obtaining sent to described heavy allocation logic module.

Wherein, heavily distribute judge module and heavy allocation logic module can be arranged in different entities, also can be arranged in same entity.When heavily distributing judge module can be arranged in different entities with heavy allocation logic module, distribute heavily that entity is under the judge module: HLR, gsmSCF or be used to tackle the heavily distribution judge module that location update request message and position between MSC/VLR and HLR are upgraded response message, as CS domain signaling transit point (STP) etc.; Entity is under the heavy allocation logic module: HSS, IMS AS etc.When heavily distributing judge module can be arranged in same entity, heavily distribute judge module and the affiliated entity of heavy allocation logic module to be all: HSS, STP, HLR, IMS AS, gsmSCF etc. with heavy allocation logic module.

The specific implementation embodiment one to embodiment 12 that can vide infra no longer describes in detail here.

Step 101: heavy allocation logic module is redistributed the UE access code according to UE current location information and self presupposed information.

Presupposed information has the corresponding relation with the UE access code different MS C/VLR number in the heavy allocation logic module, if MSC/VLR number of the MSC/VLR MSC/VLR corresponding with the UE that self stores was inconsistent under the UE that heavy allocation logic module receives was current, then heavy allocation logic module is redistributed the UE access code; Otherwise, finish current handling process.

Step 102: heavy allocation logic module is sent to the UE access code of redistributing to call out carries out point, calls out the execution point and upgrades the local UE access code that has with the UE access code that receives.

Here, calling out and carrying out point is UE, or gsmSCF and UE.

Need to prove, owing to exist the UE access code of a plurality of MSC/VLR correspondences identical in the practical application, so, the present invention upgrades in the method for UE access code, above-mentioned steps is being redistributed after logic module redistributes the UE access code, the inventive method also further comprises: whether the UE access code that heavy allocation logic module is judged current distribution with to be stored in local UE access code consistent, as if inconsistent, then continue the UE access code that the inventive method will heavily distribute and send to UE; If consistent, then heavy allocation logic module finishes flow process of the present invention.

In addition, if heavy allocation logic module has been upgraded IMS AS as required, promptly under the situation of UE generation roaming and AS change, before above-mentioned step 100 shown in Figure 1, this method also comprises: according to the login state of UE at IMS, redistribute the IMS AS of UE, specific implementation comprises:

1), then carries out heavily batch operation of AS by HSS if UE is unregistered at IMS.

2) if UE is registered at IMS, and the VCC business of this UE is unoccupied at IMS AS, and then IMS AS carries out heavily batch operation of AS.

Need to prove: if UE is registered at IMS, and the VCC business of this UE is occupied at IMS, for fear of in the VCC business owing to changing the IMS AS processing that leads to errors, IMS AS is provided with the postponement sign and postpones redistributing IMS AS, correspondingly, weigh the synchronous execution point of extremely calling out of UE access code that allocation logic module can not obtain above-mentioned heavy distribution.Be that cancellation is postponed sign and carried out the heavy assigning process of corresponding AS when the VCC of this UE business is unoccupied at IMS AS.Specific implementation can vide infra, and no longer describes in detail here.

Figure 14 is the apparatus structure schematic diagram that the present invention upgrades the UE access code, from Figure 14 as seen, the device that the present invention upgrades the UE access code comprises: the positional information sending module that is used to obtain the UE current location information, be used to redistribute the heavy allocation logic module of UE access code, and point is carried out in the calling of upgrading the UE access code, heavy assignment logic mould certainly receives the UE current location information from the positional information sending module, UE current location information according to default corresponding relation and acquisition is that described UE distributes new UE access code, and new UE access code is sent to described calling carry out point, described calling is carried out point and is upgraded self existing UE access code with the UE access code that receives.Described calling is carried out point and is UE, perhaps UE and gsmSCF.

This device also comprises: be used to judge whether heavily to distribute the heavily distribution judge module of new UE access code, heavily distribute judge module to receive the information that the UE position changes after, notify described positional information sending module to obtain the UE current location information.

In addition, further be provided with comparison module in the heavy allocation logic module, be used for determining whether described new UE access code is consistent with the UE access code of self storing, and when inconsistent new UE access code sent to described calling and carries out point.

Make purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing preferred embodiment that develops simultaneously, the present invention is described in more detail.

Fig. 2 is the flow chart of the embodiment of the invention one, and in the present embodiment, entity is HSS under the heavy allocation logic module, and heavily distributing the affiliated entity of judge module is STP, and AS does not change; Suppose in HSS the default different MS C/VLR number corresponding relation with the UE access code, variation has taken place in the UE position, and according to the agreement regulation, after MSC/VLR received the routing update request of UE transmission, this method may further comprise the steps:

Response (MAP_UPDATE_LOCATION_ack) message is upgraded in position updating request (MAP_UPDATE_LOCATION) message and position between step 200～step 203:STP interception MSC/VLR and the HLR.

Stipulate according to agreement: carry in the MAP_UPDATE_LOCATION message UE current under MSC/VLR number of MSC/VLR, promptly be new VMSC number after the UE occurrence positions changes; Carry indicating positions in the MAP_UPDATE_LOCATION_ack message and upgrade whether successful renewal indication information: upgrade successfully if this renewal indication information display update successfully, then shows this position of UE; If this upgrades the failure of indication information display update, then show this position renewal failure of UE.

After step 204:STP detects the UE position and changes, VMSC number of carrying in the MAP_UPDATE_LOCATION message of intercepting is transmitted to HSS.

If STP detects the renewal indication information that carries in the MAP_UPDATE_LOCATION_ack message and is shown as the position and upgrades successfully, change had taken place in MSC/VLR under UE then was described, at this moment, STP can be transmitted to HSS with VMSC number by self-defining message, also can duplicate the MAP_UPDATE_LOCATION message that portion intercepts and be transmitted to HSS.

In the present embodiment, STP adopts the method for duplicating the MAP_UPDATE_ LOCATION message of intercepting, and is transmitted to HSS with described VMSC number.

Step 205:HSS is according to VMSC number that receives, and the access code of the different MS C/VLR correspondence of presetting among the HSS, redistributes the UE access code.

Generally, if when adopting USSD that the UE access code is sent to UE, the UE access code of redistributing refers to E.164 number; And when by IMS message the UE access code being sent to UE, heavily the UE access code of Fen Peiing refers to AS PSI.

Need to prove, in heavy allocation logic module, can be number E.164 with different MS C/VLR number corresponding access code, also can be AS PSI.So, (1) when the UE access code of redistributing need be E.164 during number, if the access code of heavy allocation logic module storage is a number E.164, then directly use gets final product; If the access code of heavy allocation logic module storage is AS PSI, E.164 then heavy allocation logic module is converted to AS PSI and re-uses behind the number.(2) the UE access code of redistributing need be AS PSI, if the access code of heavy allocation logic module storage is AS PSI, then directly uses to get final product; If the access code of heavy allocation logic module storage is a number E.164, then heavy allocation logic module E.164 number translated is to re-use behind the AS PSI.E.164 the corresponding relation between number and the AS PSI belongs to prior art, repeats no more here.

In this step, suppose that the access code of storing among the HSS is a number E.164, so, HSS is according to new VMSC number, selects default and the new VMSC number corresponding E.164 number of consistent MSC/VLR among the HSS, as the UE access code of redistributing.

The E.164 number that step 206～step 207:HSS will redistribute is carried among the USSD, is transmitted to UE via MSC/VLR, and UE upgrades E.164 number of this locality.

Fig. 3 is the flow chart of the embodiment of the invention two, and in the present embodiment, entity is all HSS under weighing allocation logic module and heavily distributing judge module, and AS does not change; Suppose in HSS the default different MS C/VLR number corresponding relation with the UE access code; Variation has taken place in the UE position, and according to the agreement regulation, after MSC/VLR received the routing update request of UE transmission, this method may further comprise the steps:

Step 300～step 302: mutual MAP_UPDATE_LOCATION message and MAP_UPDATE_LOCATION_ack message between MSC/VLR and HLR; MSC/VLR upgrades the position via SGSN and receives (LOCATION_UPDATING_ACCEPT) forwards to UE simultaneously, dot LOCATION_UPDATING_ACCEPT message among Fig. 3 and be transmitted to UE, rather than directly send to UE's from MSC/VLR by SGSN.

Stipulate according to agreement: carry MSC/VLR TMSI in the LOCATION_UPDATING_ACCEPT message.

After step 303:UE knows that self-position changes, by USSD notice HSS.UE checks whether the MSC/VLRTMSI that carries in the LOCATION_UPDATING_ACCEPT message is consistent with the MSC/VLR TMSI that self stores, if it is inconsistent, change may take place in MSC/VLR under UE then was described, then UE is provided with and represents the change in location sign that current self-position has changed and be carried to send to HSS among the USSD.

Step 304～step 306:HSS receives the USSD from UE, and after MSC/VLR changes under definite UE, according to UE current under the access code of default different MS C/VLR correspondence among new VMSC number of MSC/VLR and the HSS, redistribute the UE access code.

HSS determines that the method whether affiliated MSC/VLR of UE changes is: HSS is carried at the IMSI International Mobile Subscriber Identity (IMSI) of UE in the ATI message, and this ATI message is sent to HLR inquire about, HLR will be carried at should IMSI MSC/VLR number and return HSS among the ATI_ack; HSS check MSC/VLR number of receiving be stored in local to should UE MSC/VLR number whether consistent, as if inconsistent, illustrate that then variation has taken place the affiliated MSC/VLR of UE.At this moment, current new VMSC number of UE is exactly MSC/VLR number that carries among the ATI_ack.

The E.164 number that step 307～step 308:HSS will redistribute is carried among the USSD, is transmitted to UE via MSC/VLR, and UE upgrades E.164 number of this locality.

Embodiment three: entity is all HSS under weighing allocation logic module and heavily distributing judge module, and AS does not change, can also initiate registration by UE and trigger renewal UE access code, specific implementation is: suppose to preserve in HSS the preceding positional information of UE registration, when HSS knows that UE successfully registers, HSS adopts the method described in step 304～step 306 to determine to redistribute the UE access code after the affiliated MSC/VLR of UE changes, and will redistribute the E.164 number that obtains and adopt the method for step 307～step 308 to send to UE, UE upgrades E.164 number of this locality.Need to prove if UE is an initial registration, promptly do not have the preceding positional information of UE registration among the HSS, so, HSS directly heavily distributes the UE access code according to the UE current location information that the method in step 304～step 306 obtains.Here, UE registration process and HSS are known that UE successfully registers and are belonged to existing known technology, can repeat no more here referring to related protocol.

UE initiates registration, I-CSCF inquires about in HSS after receiving registration message, obtain S-CSCF name or S-CSCF capability set, and registration process is carried out in continuation, after HSS learns that UE is registered, HSS adopts the method described in step 304～step 306 to determine to redistribute the UE access code after the affiliated MSC/VLR of UE changes, and will redistribute the E.164 number that obtains and adopt the method for step 307～step 308 to send to UE, and UE upgrades E.164 number of this locality.

Fig. 4 is the flow chart of the embodiment of the invention four, and in the present embodiment, entity is all IMS AS under weighing allocation logic module and heavily distributing judge module, and AS does not change; Suppose in IMS AS the default different MS C/VLR number corresponding relation with the UE access code; And hypothesis UE registers at IMS according to agreement, after S-CSCF returns the response of succeeding in registration to UE, to initiating third-party registration, return the response of succeeding in registration according to the initial filter standard or norm in the UE subscription data (iFC) data as the IMS AS of routing policy decision point as the AS of routing policy decision point.Afterwards, UE and IMS AS be two-way to carry out event subscription (SUBSCRIBE), and this method is further comprising the steps of:

Step 400～step 401: in existing UE position updating process, after UE receives that message is accepted in the position renewal, the change in location sign that the current self-position of expression has changed is set, and, owing to carried out two-way event subscription between UE and the IMS AS, therefore trigger UE described change in location sign is carried in SIP notice (Notify) message, send to IMS AS.

Because UE when registration, IMS AS and UE have carried out two-way event subscription, and therefore, after the UE occurrence positions upgraded, UE can know that variation may take place for self current affiliated MSC/VLR from IMS AS by event subscription.

Step 402:IMS AS receives the SIP Notify message from UE, and after MSC/VLR changes under definite UE, according to UE current under the access code of default different MS C/VLR correspondence among new VMSC number of MSC/VLR and the IMS AS, redistribute the UE access code.

This step IMS AS determines that whether MSC/VLR changes under the UE method and step 304～step 306 are in full accord, and only need change the heavy allocation logic module in step 304～step 306 into IMS AS and get final product, and no longer repeat here.

In addition, in this step, suppose that the access code of storing among the IMS AS is AS PSI, so, IMSAS is according to new VMSC number, selects default and the new VMSC number corresponding AS PSI of consistent MSC/VLR among the IMS AS, as the UE access code of redistributing.

Step 403:IMS AS is carried at the AS PSI that redistributes in the SIP Notify message and is transmitted to UE, and UE upgrades local AS PSI.

Figure 13 is the flow chart of the embodiment of the invention 13, flow process shown in Figure 13 is to propose at the scheme one that existing techniques in realizing is called out, main thought is before UE sets up the calling connection, upgrade the UE access code, make UE adopt the access code of current location correspondence to set up to call out and connect, thereby the correctness of route is called out in assurance.Wherein UE comprises IMS part and CS part.In the present embodiment, entity is all IMS AS under the heavy allocation logic module, and heavily distributing the affiliated entity of judge module is gsmSCF; Suppose IMSAS and gsmSCF can be close establish or set up separately, and there is synchronization mechanism between IMS AS and gsmSCF, default different MS C/VLR number and UE access code corresponding relation in as the IMS AS of heavy allocation logic module, embodiment 11 specific implementations may further comprise the steps:

The CS of step 1300～step 1302:UE partly sends setup requests by Setup message to VMSC, VMSC is according to CAMEL Subscription Information, trigger Initial DP message to gsmSCF module, and partly send Call Proceeding message to the CS of UE with NeDS function.

Step 1303:gsmSCF adopt synchronization mechanism with UE current under VMSC number of VMSC send to IMS AS.

Step 1304: before this is called out with the local UE that has stored if IMS AS judges from gsmSCF VMSC number VMSC number of affiliated VMSC inconsistent, then IMS AS is according to VMSC number that receives, and the access code of the different MS C/VLR correspondence of presetting among the IMS AS, redistribute the UE access code.

The E.164 number that step 1305～step 1306:IMS AS adopts synchronization mechanism to redistribute sends to gsmSCF, the E.164 number that gsmSCF will receive is kept at this locality, and this E.A64 number is carried in the CAMEL connect message, send to MSC/VLR.

Step 1307:IMS AS is carried at the AS PSI that redistributes and sends to UE in the PUBLISH, and UE upgrades E.164 number of this locality.

In the present embodiment, identical with embodiment ten with embodiment 11, after the step 1307, VMSC will call out the MGCF that routes to the IMS territory by IAM message according to the E.164 number that receives, and MGCF is sent to correct AS according to the described E.164 number that carries in the IAM message with calling.Such processing has guaranteed to call out and by correct AS hand-off process has been carried out in calling.

In addition, if heavy allocation logic module has been upgraded AS as required, before heavy allocation logic module was the flow process of HSS and IMS AS in Fig. 2～flow process shown in Figure 13, the inventive method also comprised:

Heavy allocation logic module is carried out following different flow process respectively according to the login state of user at IMS:

1) if UE is unregistered at IMS, then HSS carries out heavily batch operation of AS, and promptly HSS upgrades self iFC data according to the AS that has upgraded and gets final product.Wherein, the corresponding different AS of different iFC data.

2) if UE is registered at IMS, and the VCC business of this UE is unoccupied at IMS, and then IMS AS carries out heavily batch operation of AS.

Specific implementation is: IMS AS with the user ID of UE and iFC data carry in Profile-Update-Request message, and this message sent to HSS, HSS is according to the user ID of the UE that carries in this Profile-Update-Request message and the corresponding active user's of iFC Data Update self iFC data; Then HSS with the user ID of UE and iFC data carry in Push-Profile-Request message, and sending to S-CSCF, S-CSCF is according to the user ID of the UE that carries in this Profile-Update-Request message and the corresponding active user's of iFC Data Update self iFC data.Like this, after the user initiates the VCC business, can use new iFC data to commence business, use the AS after heavily distributing.

3) if UE is registered at IMS, and the VCC business of this UE is occupied at IMS, for fear of in the VCC business owing to changing AS processings that lead to errors, IMS AS is provided with and postpones the sign postponement and redistribute AS, accordingly, IMS AS will be E.164 number synchronously to UE.When the VCC of this UE business when IMS AS is unoccupied, sign is postponed in cancellation, and carries out the heavy assigning process of above-mentioned UE AS under the registered situation of IMS.

In addition, need to prove, owing to exist the UE access code of a plurality of MSC/VLR correspondences identical in the practical application, so, the present invention upgrades in the method for UE access code, redistributing after logic module redistributes the UE access code, the inventive method also further comprises: heavy allocation logic module judges whether the UE access code of current distribution is consistent with the UE access code that is stored in this locality, if inconsistent, then heavy allocation logic module sends to UE with the UE access code UE access code of redistributing that continuation the inventive method will heavily be distributed after self stores; If consistent, then heavy allocation logic module finishes flow process of the present invention.

The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
