GMLC 106 is interacted according to the request of LSC with ACF, and the position for obtaining user from RAN or UE by ACF is believed Breath, and positional information is returned into LSC, wherein, it is necessary to be interacted with UPS, it is current to obtain user from UPS during determining ACF The ACF addresses at place.In above-mentioned position fixing process, chain of command network element ACF in gruping insertion network, and RAN, UE are pertained only to, no It is related to user plane network element PAG.During GMLC obtains positional information by ACF, using user in gruping insertion network Identify to represent user, can be MSISDN (mobile user comprehensive service digital net number, Mobile Subscriber International ISDN number, wherein ISDN are the letters of Integrated Service Digital Network Claim), or IMSI (international mobile subscriber identity, International Mobile Subscriber Identification ), or both Number it is used in conjunction with.Above-mentioned mark is also referred to as the internal indicator of location service.

LSC 107 asks the positional information of user, user's mark therein using ID according to application needs to GMLC Knowledge includes MSISDN, SIP URI (initial session protocol universal resource identifier, Session Initial Protocol Universal Resource Identifier) etc. user real identification, or anonymous application layer identity, if hideing Name identity between LSC and GMLC, it is necessary to increase corresponding entity, it is ensured that the conversion between anonymous Identity and true identity, on State the outer logo that mark is also called in location service.Specifically, LSC is usually the application server in network, such as map Application server.

PDS 108 is used to receive the business information from UE and application server, and generation carrying strategy distribution is given according to this PAG, to set up suitable carrying, while PAG will also be grouped the information reporting for accessing to PDS, PDS is distributed further to using clothes Business device.When PDS is disposed, PDEA (Policy Dispatch Execution are acted on behalf of in the execution that PDS is provided with PAG Agent), PDEA can be that tPAG and/or iPAG in the independent functional entities in PAG, with PAG transmit signaling by interface, It can also be the logic function of tPAG or iPAG.

Wherein interface U1 is the interface between UE 101 and RAN 102, completes information exchange between the two, including chain of command The interaction of information and user face data；U2 is the interface of RAN 102 and PAG 104, carries UE user face datas；U3 is PAG 104 packet data interfaces for arriving internet, are communicated using IP agreement with other internet devices；S1 is ACF 103 and UPS 105 Between interface, realize UE mobile management and the download of user data；S2 is the interface between ACF 103 and RAN 102, The chain of command information of UE is carried, ACF 103 is used in location service and is obtained positional information from RAN 102；S3 be ACF103 and Interface between PAG 104, controls foundation release of user face data passage etc.；S4 is connecing between PAG 104 and PDS 108 Mouthful, realize the download for reporting and controlling rule of data connection information；L1 is the interface between LSC 107 and GMLC 106, For LSC 107 to the request position informations of GMLC 106；L2 is the interface between GMLC 106 and UPS 105, for GMLC 106 address informations that chain of command network element ACF is obtained to UPS 105；L3 is the interface between GMLC 106 and ACF 103, user GMLC 106 obtains positional information to ACF 103.

Typical location service process is that LSC 107 asks to specify the positional information of UE by L1 interfaces to GMLC 106, GMLC 106 inquires the address of the chain of command network element ACF being currently located by L2 interfaces to UPS 105, and is returned according to UPS 105 The result returned is inquired about by L3 interfaces to chain of command network element ACF 103, and ACF 103 can be further by S2 interfaces to RAN The positional information of 102 inquiry users, and GMLC 106 is returned to, GMLC 106 returns result to LSC 107 again.

In the art, LSC must first obtain application layer mark (true identity or anonymous Identity) of user, then Location service information is asked to GMLC using the outer logo of above-mentioned application layer, outer logo is mapped gruping insertion network by GMLC Internal indicator, then interacts the position for obtaining user using internal indicator with UPS, ACF.

When user accesses Internet service by gruping insertion network, such as user accesses the application of interconnection Internet map and provides The application server of business is, it is necessary to obtain the accurate positional information of user, and provide the user neighbouring ground according to positional information The information on services such as figure information and hotel, because UE is interacted using the IP address that gruping insertion network is distributed with application server, i.e., Application request and response message and content are all carried in IP packets, and at this moment application server can directly from IP packets The IP address of user is obtained in packet header, but possibly cannot obtain the accurate application layer outer logo of user, so result in application The location-based service business that server cannot be provided using packet Mobile Access Network, so as to limit the range of application of location service. And if it is desired that with IP address as user's outer logo, because IP address is typically dynamically distributes, it is impossible to using IP address only One mark user, and determine that the chain of command network element ACF of gruping insertion network is relatively difficult by IP address, therefore technically shortage can Row.

The main cause for producing above mentioned problem is that existing gruping insertion network location service uses application layer to identify (such as MSISDN, SIP URI) location service is asked by chain of command network element, and in the scene of above-mentioned lifted Internet service, due to UE is swapped with application server by user plane (i.e. IP packets), if trusty without carrying in request message Application layer identify, then application server can only obtain user user plane mark (i.e. IP address, is user described herein Carry the one kind in mark), therefore lead to not the service for using existing gruping insertion network location service to provide, limit point The service range of group access network location service, cannot also meet the demand of many Internet services.

Wherein, the user carries mark includes IP address or identity.

The above method can apply to identity and position separated network and ordinary groups accessing user.

Based on current group access network, the thought of identity position separation can be further introduced into, built a kind of new mutual Networking framework, is referred to herein as identity and position separated network.It is UE points that the general principle of identity and position separated network is With fixed identity, UE is communicated using identity instead of IP address of the prior art, and by positioned at internet The interconnection packet switch gateway (iPAG) at edge is identified for user's dispensing position, is route using station location marker, completes user Mapping and conversion between identity and station location marker.

Fig. 2 is the configuration diagram of the identity and position separated network of prior art, due in identity and position separate mesh The UE and iPAG in Fig. 1 gruping insertion networks are pertained only in network data routing process, therefore eliminates RAN, ACF, UPS in fig. 2 Deng packet access network elements.Identity and position separated network shown in Fig. 2 includes UE 201, iPAG 202, generic router (Common Router, abbreviation CR) 203, location register (Location Register, abbreviation LR) 204, each entity is said It is bright as follows：

UE 201, by gruping insertion network access internet, using user's access identity identify (Access Identity, Abbreviation AID) communicated with network other users equipment, application server as the source address of IP packets instead of IP address.

IPAG 202, is use when UE sets up grouped data and connect in iPAG in addition to the function of iPAG in possessing Fig. 1 Family distributing user AID replaces IP address, and also specified location identifies (Routing Identity, abbreviation RID) simultaneously, sets up AID With RID mapping relations (AID, RID), and the mapping relations are reported into LR；During with remote communication, can be according to distal end AID obtains the mapping relations between the AID and RID of distal end UE from LR, or is obtained from the packet of the remote subscriber for receiving The mapping relations between the AID of remote subscriber and RID are taken, so as to according to the mapping between local terminal UE and the AID and RID of distal end UE Relation completes treatment and the forwarding capability of IP packets.

CR 103, completes the calculating of Routing Protocol, and the iPAG according to where RID forwards packet to purpose UE.

LR 104, preserves the mapping relations between the iPAG AID that reports and RID, there is provided the inquiry work(according to mapping relations Can, the AID in inquiry request returns to the corresponding RID of AID.

In above-mentioned framework, U1-2 be in the interface between UE 201 and iPAG 202, i.e. Fig. 1 UE through RAN to PAG use Family face interface；M1 is the interface between iPAG 202 and LR 204, for the mapping relations for reporting and inquiring about between AID and RID； M2 is the interface between iPAG 202 and CR 203, for the data forwarding between iPAG.

Assuming that UE-A is client, UE-B is service end, and data transmission procedure is as follows：

(1) UE-A with the identity AID-A of oneself as source address, the identity AID-B of opposite end be purpose address, structure IP packets { source address=AID-A, destination address=AID-B, data load } are built, is connected by the grouped data and iPAG between IPAG-A is given in sending and receiving；

(2) iPAG-A is made according to the mapping relations between the AID and RID of UE-A and UE-B with UE-A station location markers RID-A It is source address, the station location marker RID-B of UE-B will contain the original such as AID-A and AID-B and data load as destination address Beginning packet is used as new data load { source address=RID-A, destination address=RID-B, data load for building packet { AID-A, AID-B, initial data load } }, it is routed to iPAG-B through CR；

Wherein RID-B is that iPAG-A is obtained according to the mark AID-B of UE-B from LR.

(3) iPAG-B deblockings packet, is reduced into initial packet { AID-A, the AID-B, data load of UE-A transmissions Lotus }, UE-B is then delivered a packet to according to AID-B.

When user is moved, the responsible regions of other iPAG are such as moved to, at this moment AID keeps constant, and simply RID occurs Change.Therefore can be seen that distal end UE (such as map application server) during the Operational Visit of user from said process, Can from the source address information of packet direct access AID, and be further possibly based on the existing packet shown in Fig. 1 and connect The framework of networking location service uniquely determines user's launch position business using AID, you can led to identifying (AID) using user plane Cross gruping insertion network location service framework and obtain positional information, illustrate how to obtain the address information of chain of command network element ACF below.

As shown in figure 3, be the network architecture diagram that the embodiment of the present invention obtains customer position information, in the packet shown in Fig. 1 The Hes of GMLC 306 are increased on the basis of identity and position separated network architecture combined shown in the framework and Fig. 2 of access network location service Interface L4 between LR 303, and the interface L5 between GMLC306 and PDS304, wherein iPAG 301, UPS 302, The function of LR303, PDS 304, ACF305, LSC307 also has corresponding change.

Specific implementation can be divided into two scenes：

Scene one：ACF address informations are obtained for identity and position separated network user and using L4 interfaces：
