A kind of system and method that obtains customer position information

Technical field

The present invention relates to the packet communication techniques field, relate in particular to a kind of system and method that obtains customer position information.

Background technology

grouping (PS, Packet Switching) Access Network comprises Long Term Evolution (Long Term Evolution, be called for short LTE) network, universal mobile telecommunications system (Universal Mobile Telecommunications System, be called for short UMTS) network, GSM EDGE Radio Access Network (GSM EDGE radio access network, be called for short GERAN), code division multiple access (Code Division Multiple Access, be called for short CDMA) network etc., for the user provides Internet protocol (IP, Internet Protocol) access capability, thereby make the user access the Internet network.

Fig. 1 is the configuration diagram of existing gruping insertion network location service, gruping insertion network mainly comprises subscriber equipment (User Equipment, be called for short UE) 101, Radio Access Network (Radio Access Network, be called for short RAN) 102, access control function (Access Control Function, be called for short ACF) 103, gruping insertion network closes (Packet Access Gateway, be called for short PAG) 104, user data server (User Profile Server, be called for short UPS) 105, also may comprise strategy distribution (the Policy Dispatch System of system, be called for short PDS) 108.For location service is provided, also comprise GMLC (Gateway Mobile Location Center is called for short GMLC) 106, location service client (Location Service Client is called for short LSC) 107.

UE 101 is used for transmitting/receiving wireless information, for the user presents business, and can coordinate ACF that the location service information needed is provided;

RAN 102 is used for transmitting/receiving wireless information, and carries out alternately with ACF and PAG, make ACF can with the mutual signaling information of UE, and make PAG can with UE switched-media data, provide positional information for coordinating with UE to ACF, concrete, RAN can be subdivided into chain of command entity and user entity again;

ACF 103 is used for obtaining user data from UPS, for the user provides mobile management and Bearer Control, and can further obtain alternately positional information with RAN, UE, provide positional information by GMLC for LSC, concrete, ACF is such as the mobile management entity in the LTE network (Mobility Management Entity is called for short MME), or the Serving GPRS Support Node in the UMTS network (Serving GPRS Support Node is called for short SGSN);

PAG 104 is used for providing carrying (Bearer) to realize the exchange of media data.be directed to certain business or all business, PAG comprises one or more levels packet data switched network and closes, when so-called " one-level " refers to for certain business or all business, RAN only needs can realize packet data exchanged with the Internet through a PAG, when so-called " multistage " refers to for certain business or all business, RAN need just can realize packet data exchanged with the Internet through a plurality of (more than two) PAG, concrete afterbody provides the PAG with the interaction capabilities of the Internet to be called interconnected gruping insertion network and closes (Interworking Packet Access Gateway, be called for short iPAG), the front provides the PAG of switchover capability to be called the transmission gruping insertion network and closes (Transfer Packet Access Gateway, be called for short tPAG).Concrete, iPAG is such as (the Public Data Network Gateway of the public data network gateway in the LTE network, be called for short PDN-GW) or the UMTS network in Gateway GPRS Support Node (Gateway GPRS Support Node, be called for short GGSN), tPAG such as the gateway in the LTE network (Service Gateway is called for short SGW), can be also independent community, as the functional module of ACF, such as the SGSN in the UMTS network;

UPS 105 preserves user basic information and service contracting data, and by with ACF alternately user data is downloaded to ACF, obtain user's the mobile message ACF of current place (user), thereby the callee function request that can assist to arrive this user is routed to the ACF at the current place of user.Concrete, UPS can be home subscriber server (the Home Subscriber Server in the mobile network, be called for short HSS), or attaching position register (Home Location Register, be called for short HLR), or authentication accounting server (Authentication Authorization Accounting is called for short AAA).

GMLC 106 carries out alternately with ACF according to the request of LSC, obtains user's positional information by ACF from RAN or UE, and positional information is returned to LSC, wherein determines in the process of ACF, need to be mutual with UPS, obtain the ACF address at the current place of user from UPS.In above-mentioned position fixing process, only relate to chain of command network element ACF in gruping insertion network, and RAN, UE, do not relate to user's veil PAG of unit.In GMLC obtains the process of positional information by ACF, the sign of user in gruping insertion network represents the user, it can be MSISDN (mobile user comprehensive service digital net number, Mobile Subscriber International ISDN number, wherein ISDN is the abbreviation of Integrated Service Digital Network), or IMSI (international mobile subscriber identity, International Mobile Subscriber Identification Number), perhaps both use jointly.Above-mentioned sign is also referred to as the internal indicator of location service.

LSC 107 is according to using needs, user's sign is to GMLC request user's positional information, user ID wherein comprises MSISDN, SIP URI (initial session protocol universal resource identifier, Session Initial Protocol Universal Resource Identifier) user real identification such as, it can be also anonymous application layer identity, if anonymous identity, need to increase corresponding entity between LSC and GMLC, guarantee the conversion between anonymous identity and true identity, above-mentioned sign is called again the outside sign in location service.Concrete, LSC is generally the application server in network, such as map application server.

PDS 108 is for the business information that receives from UE and application server, and generation carrying strategy distribution is to PAG according to this, and to set up suitable carrying, the information reporting that while PAG also will divide into groups to access is to PDS, and PDS further is distributed to application server.When disposing PDS, be provided with the agents PDEA (Policy Dispatch Execution Agent) of PDS in PAG, PDEA can be the standalone feature entity in PAG, transmitting signaling with tPAG and/or iPAG in PAG by interface, can be also the logic function of tPAG or iPAG.

Wherein interface U1 is the interface between UE 101 and RAN 102, completes information interaction between the two, comprises the mutual of chain of command information and user face data; U2 is interface between RAN 102 and PAG 104, carrying UE user face data; U3 be PAG 104 to the packet data interface of the Internet, use the IP agreement to communicate by letter with other internet devices; S1 is the interface between ACF 103 and UPS 105, realizes the download of UE mobile management and user data; S2 is the interface between ACF 103 and RAN 102, and the chain of command information of carrying UE is used for ACF 103 and obtains positional information from RAN 102 in location service; S3 is the interface between ACF103 and PAG 104, controls the foundation release of user face data passage etc.; S4 is the interface between PAG 104 and PDS 108, realizes reporting and the download of control law of data link information; L1 is the interface between LSC 107 and GMLC 106, is used for LSC 107 to GMLC 106 request position information; L2 is the interface between GMLC 106 and UPS 105, is used for GMLC 106 and obtains the address information of chain of command network element ACF to UPS 105; L3 is the interface between GMLC 106 and ACF 103, and user GMLC 106 obtains positional information to ACF 103.

Typical location service process is, the positional information that LSC 107 specifies UE by the L1 interface to GMLC 106 requests, GMLC 106 is by the address of L2 interface to the chain of command network element ACF at UPS 105 inquiry current places, and inquire about to chain of command network element ACF 103 by the L3 interface according to the result that UPS 105 returns, ACF 103 can be further by the positional information of S2 interface to RAN 102 inquiring users, and returning to GMLC 106, GMLC 106 returns to result LSC 107 again.

In current techniques, at first LSC must obtain user's application layer sign (true identity or anonymous identity), then use the outside sign of above-mentioned application layer to GMLC request location service information, then GMLC utilizes internal indicator and UPS, ACF to obtain alternately user's position the internal indicator of outside sign mapping gruping insertion network.

when the user accesses Internet service by gruping insertion network, access the application server of the provider of map application on the Internet such as the user, need to obtain user's positional information accurately, and according to positional information for the user information on services such as near the cartographic information providing and hotel, because IP address and application server that UE uses gruping insertion network to distribute are mutual, be that application request and response message and content all are carried in the IP packet, at this moment the application server IP address that can be directly obtains the user from IP packet packet header, but possibly can't obtain user's outside sign of application layer accurately, the location-based service business that so just causes application server can't use the grouping Mobile Access Network to provide, thereby limited the range of application of location service.And if use the IP address as the outside sign of user, due to IP address dynamic assignment normally, can't use IP address unique identification user, and and by the IP address determining that the chain of command network element ACF of gruping insertion network is more difficult, therefore technical shortage feasibility.

the main cause that produces the problems referred to above is that existing gruping insertion network location service uses the application layer sign (as MSISDN, SIP URI) by chain of command network element request location service, and in the scene of above-mentioned Internet service of lifting, because UE exchanges by user's face (being the IP packet) and application server, if do not carry application layer sign trusty in request message, can only to obtain user's user's face sign (be the IP address to application server so, a kind of in user's bearing identification described herein), therefore the service that can't use existing gruping insertion network location service to provide is provided, limited the service range of gruping insertion network location service, also can't satisfy the demand of a lot of Internet services.

Summary of the invention

Wherein, described user's bearing identification comprises IP address or identify label.

Said method can be applied to identity and locator separation network and ordinary groups access user.

Based on the current group Access Network, can further introduce the thought of identity position separation, build a kind of novel Internet architecture, be referred to herein as identity and locator separation network.The basic principle of identity and locator separation network is to distribute fixing identify label for UE, UE use identify label replacement IP of the prior art address communicates, and be the user assignment station location marker by the interconnected packet switch gateway (iPAG) that is positioned at the edge, the Internet, the use location sign is carried out route, the mapping between completing user identify label and station location marker and conversion.

Fig. 2 is the identity of prior art and the configuration diagram of locator separation network, due to UE and the iPAG only relate to Fig. 1 gruping insertion network in identity and locator separation network data routing procedure in, therefore omitted winding in RAN, ACF, UPS etc. minutes and entered network element in Fig. 2.Identity shown in Figure 2 and locator separation network comprise UE 201, iPAG 202, generic router (Common Router is called for short CR) 203, location register (Location Register is called for short LR) 204, being described as follows of each entity:

UE 201, and by the gruping insertion network accessing Internet, user's access identity sign (Access Identity is called for short AID) replaces IP address to communicate with other subscriber equipmenies of network, application server as the source address of IP packet.

IPAG 202, in possessing Fig. 1 the function of iPAG, at UE when iPAG sets up grouped data and connects, for user assignment user AID replaces the IP address, also assigned address identifies (Routing Identity is called for short RID) simultaneously, sets up AID and RID mapping relations (AID, RID), and with described mapping relations report LR; With the far-end communication process in, can obtain the AID of far-end UE and the mapping relations between RID from LR according to far-end AID, or obtain the AID of remote subscriber and the mapping relations between RID from the packet of the remote subscriber that receives, thereby processing and the forwarding capability of completing the IP packet according to AID and the mapping relations between RID of local terminal UE and far-end UE.

CR 103, complete the calculating of Routing Protocol, and according to the iPAG of RID forwarding data bag to purpose UE place.

LR 104, and the AID that preservation iPAG reports and the mapping relations between RID provide the query function according to mapping relations, according to the AID in query requests, return to RID corresponding to AID.

In above-mentioned framework, U1-2 is the interface between UE 201 and iPAG 202, and namely in Fig. 1, UE arrives the interface in the user plane of PAG through RAN; M1 is the interface between iPAG 202 and LR 204, for the mapping relations that report and inquire about between AID and RID; M2 is the interface between iPAG 202 and CR 203, is used for the data retransmission between iPAG.

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

(1) UE-A is take the identify label AID-A of oneself as the identify label AID-B of source address, opposite end as destination address, build IP packet { source address=AID-A, destination address=AID-B, data load }, by and iPAG between grouped data connect and send to iPAG-A;

(2) iPAG-A is according to the AID of UE-A and UE-B and the mapping relations between RID, with UE-A station location marker RID-A as source address, the station location marker RID-B of UE-B is as destination address, and will contain the raw data packets such as AID-A and AID-B and data load as the new data load { source address=RID-A that builds packet, destination address=RID-B, data load { AID-A, AID-B, initial data load } }, through the CR route to iPAG-B;

Wherein to be iPAG-A obtain from LR according to the sign AID-B of UE-B RID-B.

(3) iPAG-B deblocking packet is reduced into the initial packet { AID-A, AID-B, data load } that UE-A sends, then according to AID-B with Packet Generation to UE-B.

When the user is moved, as move to the zone that other iPAG are responsible for, at this moment AID remains unchanged, and just RID changes.Therefore can find out from said process, far-end UE (such as map application server) is in user's Operational Visit process, can directly obtain AID from the source address information of packet, and further might use the unique definite user's launch position business of AID based on the framework of existing gruping insertion network location service shown in Figure 1, namely can use user's face sign (AID) to obtain positional information by gruping insertion network location service framework, the following describes address information how to obtain chain of command network element ACF.

As shown in Figure 3, it is the network architecture diagram that the embodiment of the present invention is obtained customer position information, increased the interface L4 between GMLC 306 and LR 303 on the framework of gruping insertion network location service shown in Figure 1 and identity shown in Figure 2 and locator separation network architecture combined basis, and the interface L5 between GMLC306 and PDS304, wherein the function of iPAG 301, UPS 302, LR303, PDS 304, ACF305, LSC307 also has corresponding variation.

Concrete enforcement can be divided into two scenes:

Scene one: for identity and locator separation network user and use the L4 interface to obtain the ACF address information:

LSC 307, from from the packet data package of UE obtain AID, and use AID to send location service request to GMLC.

GMLC 306, receive LSC and use AID as the location service request of user ID, and use AID to send the routing iinformation request to LR, if LR returns to the ACF address, send location service request to ACF; If LR returns to internal indicator, obtain the ACF address to UPS, then send location service request to ACF, carry AID and/or internal indicator in location service request, and the positional information that ACF returns is sent to LSC;

LR 303, according to the information that iPAG reports, when preserving AID and RID mapping relations, preserve the ACF address at UE place, and/or the mapping relations between AID and internal indicator (MSISDN and/or IMSI); When GMLC query routing information, inquire about and return ACF address and/or the internal indicator (MSISDN and/or IMSI) at UE place according to AID, perhaps further to iPAG query routing information, and Query Result is returned to GMLC, perhaps return to the RID of iPAG, routing inquiry request is redirected to iPAG;
