Description
Technical field
The present invention relates to the communications field, in particular to a kind of method and system obtaining customer location.
Background technology
3GPP (3rdGenerationPartnershipProject, third generation partner program) wireless core network comprises GPRS (GeneralPacketRadioService, referred to as GPRS) grouping system (EvolvedPacketSystem of network and evolution, referred to as EPS), they are collectively referred to as packet-switched domain (PacketSwitchDomain is called for short PSDomain).
Fig. 1 shows subscriber equipment (UserEquipment, referred to as UE) access IMS domain (IPMultimediaSubsystemDomain by EPS, referred to as IMSDomain) schematic diagram, wherein the entrance network element of IMS chain of command is CSCF (ProxyCallSessionControlFunction, P-CSCF).In FIG, heavy line represents IP tunnel (medium surface), and fine line represents carries out to UE the chain of command passage that mobility or media (IP tunnel) manage.Network element in PS territory comprises: the wireless base station (eNodeB of enhancing, referred to as eNB), Mobility Management Entity (MobilityManagementEntity, referred to as MME) and user face data route processing network element (EPSGW); EPSGW comprises packet data network gateway (PacketDataNetworkGateway, referred to as PGW) and gateway (ServingGW, referred to as SGW); MME is in charge of and stores the context (such as, UE mark/user ID, mobility management states, user security parameters etc.) of UE, for user distributes temporary mark, when UE quarters at tracing area or network, is responsible for carrying out authentication to UE.ENB access is also called Long Term Evolution (LongTermEvolution, referred to as LTE) access.PGW is the mobile anchor point in EPS, is the borde gateway of EPS and packet data network (PacketDataNetwork, referred to as PDN), is responsible for the access of PDN, the function such as forwarding data between EPS and PDN.
Fig. 2 shows travelling carriage (MobileStation, referred to as MS) access the schematic diagram of IMS domain by GPRS, in fig. 2, heavy line represents IP tunnel (medium surface), and fine line represents the chain of command passage managed for carrying out mobility or media (IP tunnel) to UE.GPRS network is primarily of 3GPP Radio Access Network (GSMEDGERadioAccessNetwork/UMTSTerrestrialRadioAccessNetw ork, GERAN/UTRAN, be referred to as RAN), Serving GPRS Support Node (ServingGPRSSupportNode, referred to as SGSN), Gateway GPRS Support Node (GatewayGPRSSupportNode, referred to as GGSN) form.Do not distinguish MS and UE in description below, be referred to as UE.
"Policy and Charging Rules Function (PolicyandChargingRulesFunction, referred to as PCRF) be that strategy and charging control (PolicyandChargingControl, referred to as PCC) essential functional entities of framework, in order to control Internet Protocol-connection Access Network (IP-ConnectivityAccessNetwork, referred to as IP-CAN) strategy and charging regulation acquisition, assemble and issue.In a particular application, IP-CAN can be the set of equipment in EPS or GPRS network and interface.
In FIG, when using GPRS Tunnel Protocol (GPRSTunnelProtocol is called for short GTP) between SGW and PGW, between SGW and PCRF, interface is not had; When using proxy mobile IP protocol sixth version (ProxyMobileIPversion6 is called for short PMIPv6) between SGW and PGW, between SGW and PCRF, there is interface.
Fig. 3 is that in correlation technique, IMS domain obtains user's cell ID method flow diagram, and the method comprises:
Step S301, UE set up IP-CAN by EPS/GPRS and connect, backward IMS domain initiate business;
Step S302, UE is issuing in the invitation of P-CSCF (Invite) message the positional information can carried from EPS/GPRS, and this information is the CellID (cell ID) that UE is obtained by the broadcast of wireless base station (eNodeB or RAN).
IMS domain needs to use CellID in situations: Lawful Interception (Lawfulinterception); IMS session charging record (IMSsessionchargingrecords); Urgent call target---public safety answering point (PublicSafetyAnsweringPoint is called for short PSAP) is selected; Trigger the IMS business (localizedIMSservices) of localization.The form of this CellID can be TAI (TrackingAreaIdentifier, tracking area identification) and ECGI (E-UTRANCellGlobalIdentifier, the universal land radio access web cellular global identity of evolution).
Inventor finds that the CellID information in correlation technique is that UE reports network, but UE is subscriber equipment, not exclusively by network control, its information reported is thought incredible by network, therefore cannot meet the demand of the genuine and believable user CellID of IMS domain needs, cause the fail safe of IMS business to reduce.
Summary of the invention
