Description
Technical field
The present invention relates to the wireless lan (wlan) access technology, relate in particular to a kind of method that accessing position information is provided.
Background technology
In emergence call services such as 110,119 or 120, if the calling party provides accessing position information in call information when access network, then the callee just can determine calling party's particular location according to the accessing position information that provides in the call information after receiving call information.Therefore, in being similar to business emergence call services such as 110,119 or 120, that need to determine calling party's particular location, provide accessing position information to be very important.In the WLAN technology, subscriber equipment (UE) also needs the Application Function (AF) in IMS that UE is provided accessing position information when inserting IP Multimedia System (IMS).
IMS is defined in the R5 version by the third generation partnership project (3GPP) of being responsible for formulation WCDMA standard.The proposition of IMS provides multimedia service and platform towards the grouped data packet switch for the IP-based mobile network of the next generation, and its core characteristics are based on the independence of Session Initiation Protocol and access.Main functional entity comprises AF and is used for service quality (QoS) management Strategy decision making function entity (PDF) among the IMS.Wherein, AF mainly comprise functions such as control user registration, session controlling call entity (CSCF), manage the home subscriber server (HSS) of user contracting data concentratedly and the application server (AS) of miscellaneous service logic control function be provided.
CSCF is the core of IMS, and it can be divided into following three types according to logic function: proxy CSCF (P-CSCF), inquiry CSCF (I-CSCF) and serving CSCF (S-CSCF).Wherein, P-CSCF is the inlet that user terminal inserts the IMS system, can realize agency (Proxy) and user agent (User Agent) function in the Session Initiation Protocol; I-CSCF can select correct S-CSCF for the user by inquiry HSS, sends call request to S-CSCF simultaneously; S-CSCF is used for finishing all sessions of network to be handled, and comprises the authentification of user authentication, and triggers corresponding business.
As shown in Figure 1, Fig. 1 provides the schematic diagram of accessing position information when inserting IMS for UE in the prior art.Wherein, path (Path) the 1st, UE provides the path of accessing position information when inserting IMS according to being defined in of present 3GPP standard, and Path 2 is that UE merges the path that accessing position information is provided when being defined in of standard group (TISPAN) standard inserted IMS according to ETSI research telecommunications internet.In Path 1, be Gm between UE and the P-CSCF, P-CSCF and (I/S-CSCF) between be Mw, be ISC interface between I/S-CSCF and the AS; In Path 2, between P-CSCF and the NACF/CLF E2 interface, can realize information interaction between each entity also can realizing the transmission of UE accessing position information between each entity by Gm, Mw, ISC interface or E2 interface.In addition, between AS and HSS Sh interface, can carry out information interaction by Sh interface between AS and the HSS, also can carry out the transmission of UE accessing position information.Be Cx interface between I/S-CSCF and HSS, can carry out information interaction by Cx interface between I/S-CSCF and the HSS at present, but cannot carry out the transmission of UE accessing position information.
For Path 1, the 3GPP standard is expanded Session Initiation Protocol at present, has increased the P-Access-Network-Info header field that is used to carry the UE accessing position information in sip message.The P-Access-Network-Info header field includes two information: one is access style, can be designated IEEE-802.11a or IEEE-802.11b; Another is an access information, and its form is: extension-access-info.3GPP standard code at present, when UE inserts IMS or after the UE accessing position information changes, the information interaction that UE can be by self and CSCF or AS offers CSCF or AS with self accessing position information.At UE during as caller, UE is filled up to self accessing position information in the P-Access-Network-Info header field of sip message and sends to CSCF and AS, and CSCF and AS obtain the UE accessing position information from the P-Access-Network-Info header field of sip message.At UE when called, CSCF or AS can send the sip message that carries UE accessing position information query requests to UE, UE is carried at the UE accessing position information in the P-Access-Network-Info header field of sip response message and returns to CSCF or AS, and CSCF or AS obtain the UE accessing position information from the P-Access-Network-Info header field of sip response message.
For Path 2, TISPAN standard code at present, when UE inserts IMS or after the UE accessing position information changes, UE is carried at self accessing position information in the P-Access-Network-Info header field of sip message and sends to access control entity (AC), AC obtains the UE accessing position information from the P-Access-Network-Info header field of sip message, the UE accessing position information that obtains is reported network access configuration function entity (NACF); After NACF is UE distributing IP address, will be kept at for the UE accessing position information of UE IP address allocated and reception in the logical functional entity (CLF); P-CSCF adopts the diameter agreement to obtain the UE accessing position information by the E2 interface from the CLF inquiry, and by the information interaction with I/S-CSCF or AS the UE accessing position information is carried in the P-Access-Network-Info header field of sip message or sip response message and offers I/S-CSCF or AS.
The process that provides the UE accessing position information from above-mentioned two kinds of standards as can be seen, when UE inserts IMS or after the UE accessing position information changes, the UE accessing position information has offered CSCF or AS by the information interaction between UE and CSCF or UE and the AS, and the UE accessing position information does not offer HSS.Because the UE accessing position information does not offer HSS, in HSS, do not preserve the UE accessing position information, so HSS also can't provide UE accessing position information to AS in the prior art, AS can only obtain the UE accessing position information by the information interaction of carrying out between self and the UE.If UE is busy with conversation or other business, AS can't carry out information interaction with UE, and AS also just can't obtain the UE accessing position information.
