Background technology

3GPP and non-3GPP normal structure are being studied a kind of new access module at present: family's access (Home), UE (subscriber equipment) passes through wireless family access point, the frequency spectrum of the usage license is (as UTRAN (UMTS Terrestrial radio access network, UMTS Terrestrial Radio Access Network)/E-UTRAN (UMTS Terrestrial radio access network of evolution, Evolved UMTS Terrestrial Radio AccessNetwork)/CDMA (code division multiple access access, Code Division Multiple Access)/Wimax (micro-wave access global inter communication, Worldwide Interoperability for Microwave Access/WLAN (WLAN (wireless local area network), Wireless Local Area Network/HRPD (HRPD (high rate packet data), etc. High Rate PacketData)) frequency spectrum that Radio Access Network is used), by general IP access network (as DSL (Digital Subscriber Line, Digital Subscriber Line), cable broadband (Cable broadband)) be connected to the mobile network of operator.The system architecture diagram of family's access as shown in Figure 1, comprise wireless family access point, the frequency spectrum of the usage license, by general IP access network, UE is connected to mobile network's (some forum also is referred to as Femtocells) of operator, it comprises HNB (Home NodeB), operates in the wireless family access point of UTRAN frequency spectrum; HeNB (Home evolved NodeB), operate in the wireless family access point of E-UTRAN frequency spectrum; Home non-3GPP WAP (Home non-3GPPwireless access point), operate in the wireless family access point of non-3GPP network (as networks such as CDMA/Wimax/WLAN/HRPD) frequency spectrum.The Gateway Network Element of wireless family access point, can be HNBGW, HeNB GW or Home non-3GPP WAP GW, carry out wireless family access point management and access control, collect wireless family access point, the functions such as data of the signaling between the network element in route and forwarding wireless family access point and mobile network.Mobility Management Entity (MME, MobilityManagement Entity), be responsible for the chain of command mobile management in the E-UTRAN network, comprises user's context and mobile status management, distributing user temporary identity sign etc.Service universal grouping wireless business supporting node (SGSN, Serving GPRS Supporting Node), for realizing the functions such as the forwarding of GPRS/UMTS network route, mobile management, session management and user profile storage.Non-3GPP gateway entity (non-3GPP GW) realizes that the functions such as mobile management in the non-3GPP network, session management are (for wlan network, non-3GPP GW is evolution packet data gateway (EPDG, EvolvedPacket Data Gateway); For the Wimax network, non-3GPP GW is access business network gateway (Access Service Network Gateway, ASN GW); For cdma network, non-3GPPGW is IAD (Access Gateway, AGW); For the HRPD network, non-3GPP GW is high-speed packet data service gateway (HSGW, HRPD Serving Gateway)).Home subscriber server (HSS, Home Subscriber Server) is for storing user subscription information.Authenticate, authorize accounting server (AAA Server, Authentication, Authorization and Accounting Server) for UE is carried out to access authentication, mandate and billing function.Family's access-in management server (HMS, Home Management Server), the management function of responsible wireless family access point.HMS can be an independently network element, also can be integrated in HSS.HMS also can directly be connected with wireless family access point, and this framework is not restricted.

Illustrate: this framework does not also mean that final family's connecting system framework, last framework may with this framework difference to some extent, this patent is not restricted.

Access specific wireless family access point or specific WAP (wireless access point) in order to limit UE, CSG (closed user's group, Closed Subscriber Group) mechanism is introduced into.CSG identify some UE (or user, user), these UE allow one or several communities of access carriers, but these communities are the restriction accesses to other UE.A CSG zone (area) comprises Yi Ge community or several community, and these little area definitions access one group of UE (or user).A CSG zone identifies with CSG sign (ID).There is signing permission CSG list (Allowed CSG list (access CSG list) in UE, also can be referred to as CSG white list (CSG White List)), comprise one or several CSG ID (also being referred to as CSG ID list) in Allowed CSG List, UE only allows access in corresponding CSG community in CSG ID list.The access module of a CSG cell (CSG community) can be closed access mode.When the access module of CSG cell (CSG community) is closed access mode, only allow CSG user to access this CSG cell, non-CSG user does not allow access.

In prior art, when network side paging UE, in order to reduce beep-page message, introduced a kind of mechanism of calling optimization: core management network element is known and will be carried out calling optimization when initiating paging, in the CSG ID that UE that can be corresponding in signing Allowed CSG List allows to access, carries out paging.So just avoided to this core management network element location management region memory all HeNB carry out paging, reduced paging range, reduced beep-page message.

Calling optimization under CSG mechanism does not consider that there is urgent call (EmergencyCall in UE at present, EMC) scene during business, so just may bring following problem: when UE allows the CSG cell 1 of access to move to a CSG cell 2 who does not allow access from one, processing according to prior art, due to CSG cell 1 and CSG cell 2 all at same TAI (Tracking Area Identity, tracking area identification), in List, UE can not initiate the TAU flow process.If the current EMC business that exists of UE, allow UE resident at CSG cell 2, but this CSG cell 2 is not at UE in signing AllowedCSG List.If there is the EMC business in UE and resides in CSG cell 2, core management network element is now carried out calling optimization, can be in the signing Allowed CSG List of UE paging UE, can be at CSG cell2 paging UE, like this with regard to paging less than UE.Equally, when UE does not allow the CSG cell 2 of access to move to a CSG cell 3 who does not allow access from one, when core management network element is carried out calling optimization, can be at CSG cell3 paging UE, still can there is the problem of paging less than UE, cause the ongoing EMC service disconnection of UE, affect user's business experience.

When UE moves to a zone that does not allow access, if optional UE initiates the EMC business, UE can initiate the service request flow process, and core management network element can be accepted the service request of the EMC of UE initiation, can know the current EMC of the existence business of UE.When core management network element is sent out beep-page message, when knowing that there is the EMC business in UE, and current execution calling optimization, cancel calling optimization, send beep-page message in TAI List, because TAI List comprises the CSG ID of the Zone Full that core network element management is lower, can guarantee that like this paging arrives UE, the continuity of assurance UE emergence call service.

Annotate: in the manner, owing to cancelling when calling optimization is processed the CSG CAMEL-Subscription-Information (as Allowed CSG List or list of CSG IDs for paging etc.) that can not comprise UE in beep-page message, if perhaps (UE does not have the CSG subscription data, this UE may be the UE of non-CSG or the UE of grand network (macro network)), core management network element is issued the CSG CAMEL-Subscription-Information that also there is no UE in the beep-page message of IAD or access network element, if while finding that described paging request message does not comprise the CSG CAMEL-Subscription-Information of UE like this after the IAD with CSG function or access network element are received paging request message, described IAD or access network element can not determine that cancelling calling optimization processes, may think that this UE is the UE of non-CSG or the UE of grand network, thereby paging UE in the CSG cell not under closed mode, cause paging less than UE, affected user's business experience.

So when core management network element is known the cancellation calling optimization, can comprise in the beep-page message that is handed down to IAD or access network element and whether cancel the indication information that calling optimization is processed, when if receiving beep-page message, IAD or access network element comprise the indication information of cancelling calling optimization follow-up, cancelling calling optimization processes, , IAD (comprises the CSG cell of the management area that belongs to described UE or the access network element of CSG cell at community or the access network element in the management area that belongs to UE of the management area that belongs to described UE, no matter whether the CSG ID of this CSG Cell or CSG Cell has signing for UE) the described UE of paging or access network element be at the community of the management area that belongs to described UE (the CSG cell that comprises the management area that belongs to described UE, no matter whether the CSG ID of this CSG Cell or CSG Cell has signing for UE) the described UE of paging, can guarantee that like this paging arrives UE, guarantee the continuity of UE emergence call service.

Concrete, for the described indication information of whether cancelling the calling optimization processing, the following form of expression can be arranged, the present invention does not limit:

(1) cell that can comprise the processing of cancellation calling optimization, as indication information, is cancelled calling optimization as comprised " NOTPaging Optimization " indication; If the execution calling optimization, do not comprise this indication information.Perhaps

(2) cell that can comprise the calling optimization processing, as indication information, is processed as comprised " PagingOptimization " indication calling optimization; Process if cancel calling optimization, do not comprise this indication information.Perhaps,

(3) can comprise that " Paging Optimization type " types value indicates whether to cancel calling optimization, as carried out calling optimization, " Paging Optimization type " types value being set is " YES ", and calling optimization is carried out in indication; As cancel calling optimization and process, " Paging Optimization type " types value being set is " NO ", indication is cancelled calling optimization and is processed;

After IAD or access network element are received beep-page message, if know the indication information of described cancellation calling optimization (, beep-page message comprises the indication information of cancelling calling optimization), IAD (comprises the CSG cell of the management area that belongs to described UE or the access network element of CSG cell at community or the access network element in the management area that belongs to UE of the management area that belongs to described UE, no matter whether the CSG ID of this CSG Cell or CSG Cell has signing for UE) the described UE of paging or access network element be at the community of the management area that the belongs to described UE (CSGcell that comprises the management area that belongs to described UE, no matter whether the CSG ID of this CSG Cell or CSG Cell has signing for UE) the described UE of paging.Can guarantee that like this paging arrives UE, guarantee the continuity of UE emergence call service.

Top processing also can be applied to the processing under non-EMC scene, , UE does not have the EMC business, but in core management network element, calling optimization is cancelled in configuration, perhaps, do not configure and support calling optimization in core management network element, core management network element is not carried out the processing of calling optimization, the CSG CAMEL-Subscription-Information that does not also comprise UE in the beep-page message sent, if while finding that described paging request message does not comprise the CSG CAMEL-Subscription-Information of UE like this after the IAD with CSG function or access network element are received paging request message, described IAD or access network element can not determine that cancelling calling optimization processes, may think that this UE is the UE of non-CSG or the UE of grand network, thereby paging UE in the CSG cell not under closed mode, cause paging less than UE, affected user's business experience.So also need to comprise the indication information of whether cancelling the calling optimization processing in the beep-page message that under this scene, core management network element sends, if comprise when IAD or access network element receive beep-page message the indication information of cancelling calling optimization like this, IAD (comprises the CSG cell of the management area that belongs to described UE or the access network element of CSG cell at community or the access network element of the management area that belongs to described UE, no matter whether the CSG ID of this CSG Cell or CSG Cell has signing for UE) the described UE of paging or access network element be at the community of the management area that belongs to described UE (the CSG cell that comprises the management area that belongs to described UE, no matter whether the CSG ID of this CSG Cell or CSG Cell has signing for UE) the described UE of paging, can guarantee that like this paging arrives UE, guarantee the continuity of UE emergence call service.
