Description
Technical Field
The present invention relates to the field of communications, and in particular, to a method and an apparatus for providing location information.
Background
An Evolved Packet System (EPS) in the third Generation Partnership Project (3rd Generation Partnership Project, abbreviated as 3GPP) is composed of an Evolved Universal mobile telecommunications System Terrestrial Radio Access Network (Evolved Universal mobile telecommunications Network, abbreviated as E-UTRAN), a mobile Management unit (Mobility Management Entity, abbreviated as MME), a Serving Gateway (Serving Gateway, abbreviated as S-GW), a Packet Data Network Gateway (Packet Data Network Gateway, abbreviated as P-GW or PDN GW), a Home Subscriber Server (HSS), a Policy and Charging Rules Function (Policy and Charging Rules Function, abbreviated as PCRF) Entity and other support nodes.
Fig. 1 is an architecture diagram of connection to an EPC network according to various access methods in the related art, as shown in fig. 1, including a 3GPP access, a trusted WLAN access and an untrusted WLAN access through an ePDG, and IMS is one of packet data services provided by an operator. The MME mobile management unit is responsible for the related work of control planes such as the mobility management, the processing of non-access stratum signaling, the management of user mobile management context and the like; the S-GW is an access gateway device connected with the E-UTRAN, forwards data between the E-UTRAN and the PDN GW, and is responsible for caching paging waiting data; the P-GW is a border gateway between the EPS and a Packet Data Network (PDN for short), and is responsible for accessing the PDN and forwarding Data between the EPS and the PDN; the PCRF is a policy and charging rule function entity, and is connected to an operator network Protocol (Internet Protocol, abbreviated as IP) Service network through a receiving interface Rx to obtain Service information, and is connected to a gateway device in the network through a Gx/Gxa/Gxc interface to initiate establishment of an IP bearer, ensure Quality of Service (QoS) of Service data, and perform charging control. The EPS supports the intercommunication with the non-3 GPP network and realizes the intercommunication with the non-3 GPP network through an S2a/S2b/S2c interface. Non-3 GPP networks include trusted non-3 GPP networks and untrusted non-3 GPP networks. The IP access of the trusted non-3 GPP network can be directly interfaced with the P-GW through the S2 a; the IP access of the untrusted non-3 GPP network needs to be connected to the PDN GW through an Evolved Packet Data Gateway (ePDG), and an interface between the ePDG and the PDN GW is S2 b.
With the increasing maturity of Wireless Local Area Network (WLAN) access technology and the demand of users for high-speed Wireless access Networks, operators at home and abroad are actively developing WLAN services. The EPS (Evolved Packet System) supports the intercommunication with non-3 GPP network (e.g. WLAN) through S2a/S2b/S2c interface. Non-3 GPP networks include trusted non-3 GPP networks and untrusted non-3 GPP networks, so WLAN access networks to the 3GPP evolved Packet Core network epc (evolved Packet Core network) are also classified into trusted WLAN access networks twan (trusted WLAN access networks) and untrusted WLAN access networks (untrusted WLAN access networks). The trusted WLAN access Network can be directly connected with a Packet Data Network Gateway (PDN GW) through an S2a interface; the untrusted WLAN access network is connected to the PDN GW through an ePDG (Evolved Packet Data Gateway), where an interface between the ePDG and the PDN GW is S2 b.
Ims (IP Multimedia subsystem) is an IP Multimedia system, a new form of Multimedia service, which can meet the requirements of more innovative and diversified Multimedia services for end-users. The IMS is considered as a core technology of a next-generation network, and is also an important way to solve the convergence of mobile and fixed networks and introduce differentiated services such as triple convergence of voice, data, and video. The IMS architecture and the design of cscf (call Session Control function) utilize the soft switch technology, and implement service and Control separation, and call Control and media transmission separation. Although IMS is a system developed by 3GPP for mobile users to access multimedia services, it has been practically limited to serving mobile users only, since it fully integrates the technology of the IP domain and works closely with other organizations in the development stage. The 3GPP is always conducting standardization studies of IMS, starting fromRelease 5, which supports the center of providing end-to-end multimedia services and clustering multimedia services in the UMTS core network. In Release 6 of 3GPP, IMS has been defined as a multimedia service core network supporting all IP Access networks, and can support any kind of mobile or fixed, wired or wireless IP-can (IP Connectivity Access networks), including WCDMA, CDMA2000, Ethernet, xDSL and WLAN. In the 3GPP architecture, the IMS system belongs to an IP service provided by an operator, and the location is as shown in the architecture of fig. 1. The network element in the IMS system that is closely related to the requirements of the present invention is the P-CSCF, i.e., the Proxy Call Session Control function (Proxy-Call Session Control function), which is the first contact node (in the signaling plane) of the user in the IMS, and from the SIP perspective, it is an outbound/inbound SIP Proxy server, and all SIP signaling, whether from User Equipment (UE) or to UE, must pass through the P-CSCF. The UE may obtain the address of the P-CSCF using the local CSCF discovery mechanism. The P-CSCF is responsible for validating the request, forwarding it to the specified target, and processing and forwarding the response. In the IMS connection establishment and management process, the system needs to query and manage a service specified or supported by the user according to the current location of the user, for example, when the user initiates an IMS emergency call service, the network selects a nearby emergency call center for the user according to the location information of the user, and the like. The user position information can be provided from two sources, one source is provided by UE, and currently, a corresponding field in an SIP message header can be carried; another is provided by the network, such as the identity of the base station where the UE is located, the WLAN access identity, etc. Typically, the user location information provided by the network is considered to be more reliable information than the user provides.
The above IMS characteristics determine that in a scenario where there is both 3GPP wireless signal coverage and WLAN coverage, the UE can initiate an IMS call through a packet data connection established by 3GPP or can also pass through WLAN. Fig. 2 is a diagram illustrating a UE switching a packet data connection from 3GPP to WLAN according to the related art, as shown in fig. 2, for a UE supporting multiple access (supporting packet data connection established to a core network at both WLAN and 3GPP), services running on 3GPP or part of services may be migrated to the WLAN side according to the change of network environment, and vice versa, for example, if the number of users on 3GPP side is too large to cause network congestion, the UE may migrate IMS services to the WLAN side (as shown in fig. 2), or switch the whole packet data connection to the WLAN side, so as to provide guarantee for user experience. In the prior art, when an IMS service is handed over from 3GPP to WLAN, a UE may provide user location information (such as cell id) that is connected to a 3GPP network last time to the network, but currently, in such a multi-access scenario, the network is not supported to provide the cell id information, so that such information provision needs to be completely supported by the user equipment, and the reliability of the information cannot be guaranteed.
The present invention provides a method for providing user location information provided by a network, so that an IMS system can obtain the cell id information provided by the network and the latest connection of a UE in a WLAN access scenario of an IMS service.
An effective solution is not provided for the problem of how to acquire user location information in a multi-access scenario in the related art.
