Description
Technical field
The present invention relates to the communications field, in particular to method for providing position information and device.
Background technology
Third generation partner program (3rd Generation Partnership Project, referred to as 3GPP) evolution
Grouping system (Evolved Packet System, referred to as EPS) wirelessly connect by the UMTS land of evolution
Network (Evolved Universal Terrestrial Radio Access Network, referred to as E-UTRAN), moving tube
Manage unit (Mobility Management Entity, referred to as MME), gateway (Serving Gateway, is referred to as
S-GW), grouped data network gateway (Packet Data Network Gateway, referred to as P-GW or PDN GW), ownership
Client server (Home Subscriber Server, referred to as HSS), "Policy and Charging Rules Function (Policy and
Charging Rules Function, referred to as PCRF) entity and other support nodes composition.
Fig. 1 is the Organization Chart that EPC networks are connected to according to plurality of access modes in correlation technique, as shown in figure 1, including
3GPP is accessed, and the WLAN accesses of trust and non-trusted WLAN are accessed by ePDG, the packet count that IMS provides as operator
According to one kind of business.MME mobile management units are responsible on mobile management, the processing of Non-Access Stratum signaling and user's mobile management
The related work of the chains of command such as management hereafter;S-GW is the accessing gateway equipment being connected with E-UTRAN, in E-UTRAN and PDN
Data are forwarded between GW, and are responsible for caching the pending datas such as paging;P-GW is then EPS and packet data network
The borde gateway of (Packet Data Network, referred to as PDN), it is responsible for PDN access and data is forwarded between EPS and PDN
Etc. function;PCRF is "Policy and Charging Rules Function entity, and it passes through receiving interface Rx and carrier network agreement (Internet
Protocol, referred to as IP) business network is connected, obtain business information, in addition, it pass through Gx/Gxa/Gxc interfaces with network
Gateway device be connected, be responsible for initiating the foundation of IP carryings, ensure service quality (the Quality of of business datum
Service, referred to as QoS), and carry out charging control.EPS supports the intercommunication with non-3 GPP network, and passes through S2a/S2b/S2c
Interface realizes the intercommunication with non-3 GPP network.Non-3 GPP network includes trusted non-3 GPP network and trustless non-3 gpp net
Network.The IP accesses of trusted non-3 GPP network can directly pass through S2a and P-GW interfaces;The IP accesses of trustless non-3 GPP network
Need with PDN GW to be connected by ePDG (Evolved Packet Data Gateway, the data gateway of evolution), ePDG with
Interface between PDN GW is S2b.
With WLAN (Wireless Local Area Networks, WLAN) access technology increasingly into
It is ripe, and user greatly developing WLAN business to the demand of High-speed wireless access network, domestic and overseas operators.EPS
(Evolved Packet System evolved packet systems) supports to realize by S2a/S2b/S2c interfaces and non-3 GPP network
(e.g.WLAN) intercommunication.Non-3 GPP network includes trusted non-3 GPP network and non-trusted non-3 GPP network, so WLAN connects
Network to 3GPP evolution block core nets EPC (the Evolved Packet Core Network) WLAN for being also classified into trusting and access
Net TWAN (trusted WLAN access network) and non-trusted WLAN access networks (untrusted WLAN access
network).The WLAN access networks of trust can directly pass through S2a interfaces and grouped data network gateway PDN GW (Packet
Data Network Gateway) connection;Non-trusted WLAN access networks will pass through ePDG (Evolved Packet Data
Gateway, evolution packet data gateway) it is connected with PDN GW, the interface between ePDG and PDN GW is S2b.
IMS (IP Multimedia Subsystem) is IP multimedia systems, is a kind of new multimedia service form,
The demand for more novel, the more diversified multimedia service of terminal client that it disclosure satisfy that.IMS is considered as the core of next generation network
Heart technology, and solve movement and merged with fixed network, introduce the important side of the differentiated services such as voice, data, video Triple Fusion
Formula.The design of IMS architectures and CSCF (Call Session Control Function) make use of Softswitch technology, real
Show business to be separated with control phase separation, Call- Control1 and media transmission.Although IMS is that 3GPP accesses more matchmakers for mobile subscriber
Body service and the system developed, but because it has merged the technology in IP domains comprehensively, and the development phase with regard to and other tissues carry out
Hand-in-glove so that IMS has actually been not limited solely to only be serviced for mobile subscriber.3GPP is carrying out IMS's always
Standardization Research, since Release 5, support that IMS is that end-to-end multimedia service and cluster are provided in UMTS core networks
The center of multimedia service.In 3GPP Release 6, IMS is defined as supporting the multimedia of all IP access networks
Business core net, any mobile or fixed, wired or wireless IP-CAN (IP can be supported
Connectivity Access Networks), including WCDMA, CDMA2000, Ethernet, xDSL and WLAN etc..
In 3GPP frameworks, IMS systems belong to the IP operation of operator's offer, and position is as shown in Fig. 1 frameworks.In IMS systems with the present invention
The close network element of demand relation be P-CSCF i.e. Proxy Call Session Control Function (Proxy-Call Session Control
Funtion), it is first contact node (in signaling plane) of user in IMS, and it is one and gone out from the perspective of SIP
Stand/the sip proxy server of inbound, all SIP signalings, either from user equipment (UE), be also destined to UE, all
Have to pass through P-CSCF.UE can obtain P-CSCF address using local CSCF discovery mechanisms.P-CSCF is responsible for checking request,
Forward it to the target specified, and processing and transmitted response.During IMS connections are established and are managed, system needs
The business specified or supported according to the current position enquiring of user and management user, for example initiate IMS urgent call industry in user
During business, network is the emergency call center of user's selection nearby etc. according to the positional information of user.Customer position information, which provides, to be come
Source can have two kinds, and a kind of is that UE oneself is provided, and has corresponding field to carry in sip message head at present;Other one
Kind is provided by network, such as the Base Station Identification residing for UE, WLAN access marks etc..Under normal circumstances, the user that network provides
Positional information is considered as the more reliable information provided than user.
Above-mentioned IMS characteristic, determine under the scene for having the covering of 3GPP wireless signals and WLAN coverings at the same time, UE both may be used
WLAN can also be passed through by initiating IMS callings with the grouped data connection established by 3GPP.Fig. 2 is will according to the UE of correlation technique
Grouped data connects the schematic diagram that WLAN is switched to from 3GPP, as shown in Fig. 2 for supporting multiple access (to support simultaneously in WLAN
Establish to the grouped data of core net and connect with 3GPP) UE, can be according to the change of network environment, the industry that will be run on 3GPP
Business or partial service move to WLAN sides, and vice versa, such as if when 3GPP sides number of users causes greatly very much network congestion,
UE can be by IMS business migrations to WLAN sides (as shown in Figure 2), or whole grouped data is connected and is switched to WLAN sides, are
Consumer's Experience provides safeguard.In the prior art, IMS business from 3GPP be switched to WLAN when, UE can provide it is the last even
The customer position information (such as cell id) for being connected to 3GPP networks arrives network, but is not propped up under this multiple access scene at present
Hold network and cell id information is provided, this, which allows for the offer of this category information, needs to be completely dependent on the support of user equipment, and information
Reliability can not be guaranteed.
The present invention provides method in view of the above-mentioned problems, the present invention provides the customer position information that a kind of network provides so that
IMS systems in IMS business in the case where WLAN accesses scene, can get the cell id of the last connections of UE of network offer
Information.
