Abstract
The invention discloses an IP multimedia subsystem (IMS) access method which comprises the following steps: firstly, an IMS client side acquires IMSI (International Mobile Subscriber Identity) of a terminal card and transmits an inquiry request carrying the IMSI to an attribution inquiry function module; secondly, the attribution inquiry function module receives the inquiry request and inquires the corresponding relation of stored IMSI and attribution area information according to the IMSI, so as to acquire the attribution area information corresponding to the IMSI and transmit the attribution area information to the IMS client side; and thirdly, the IMS client side performs IMS access according to the attribution area information corresponding to the IMSI. In the invention, the IMS client side inquires the corresponding relation of the IMSI and the attribution area information according to the IMSI of the terminal card so as to acquire the attribution area information corresponding to the IMSI and realize IMS access through the attribution area information, so that the IMS access of IMS client sides using SIM (Subscriber Identity Module) or USIM (Universal Subscriber Identity Module) cards; and the access process is simple.
Description
Technical field
The present invention relates to the communications field, relate in particular to the method and apparatus that a kind of IMS inserts.
Background technology
Under the promotion of multiple business, 3GPP (3G (Third Generation) Moblie standardization partnership) has released IMS (IP Multimedia System) framework, provide a kind of structure of standardized opening to realize diversified IP multimedia application, abundanter business impression is provided.
3GPP has introduced the access that ISIM (IMS Subscriber Identity Module, IMS user identification module) is used for IMS.The IMS framework specifically comprises CSCF (Call Session ControlFunction, CSCF) and HSS (Home Subscriber Server, home signature user server) functional entity.
Wherein, CSCF comprises P-CSCF (proxy CSCF), I-CSCF (inquiry CSCF) and 3 logic entities of S-CSCF (serving CSCF), and these logic entities can also may be functional modules different in the same physical equipment on different physical equipments.P-CSCF is the access point of terminal user access to IMS, is used to finish user's registration, service quality (QoS) control and safety management etc.; I-CSCF is responsible for the distribution of alleyway, management S-CSCF between the IMS territory, externally hides network topology structure and configuration information and produce metering data etc.; S-CSCF is the service switching center of IMS, is used to carry out session control, peace preservation association's speech phase, managing user information, generation charge information etc.
HSS preserves user contracting data, is used for the processing of network enabled entity to calling and session, and the data of ISIM just are stored among the HSS.
Fig. 1 is the standard access process of IMS:
In user's ISIM card, store user's IMPI (privately owned sign), IMPU (public identify), HDN (home domain information), P-CSCF address, user's the information of KI K.The IMS client reads the above-mentioned information of storing in the ISIM card, and sends the Sip Register request that carries authentication informations such as IMPI, IMPU, HDN to P-CSCF; HDN information in the register requirement that P-CSCF sends by the IMS client finds the home domain at user place, transmits SipRegister message to the I-CSCF of user place home domain, finishes IMS register and authentication process.
But, there are a large amount of SIM card and usim card in the existing network, compare the ISIM card, there are not IMPI, IMPU, HDN, P-CSCF in SIM card and the usim card, have only user's KI K.Therefore, if the user uses the SIM/USIM card to insert the IMS terminal, because the IMS terminal can't be submitted the home domain information HDN at terminal place to P-CSCF to, P-CSCF can't obtain the I-CSCF of user place home domain, thereby can't finish the intervention authentication process of IMS, cause the user can't enjoy the IMS service.
At the problems referred to above, the prior art one IMS normalized definition by 3GPP the IMS client derive the derived rule of information such as IMPI, IMPU, HDN by the IMSI (International Mobile Subscriber Identity, international mobile subscriber identity) of usim card:
IMPI：″<IMSI>@ims.mnc<MNC>.mcc<MCC>.3gppnetwork.org″
IMPU：″sip:<IMSI>@ims.mnc<MNC>.mcc<MCC>.3gppnetwork.org″
HDN：ims.mnc<MNC>.mcc<MCC>.3gppnetwork.org
For example, if user IMSI be 234150999999999 (MCC=234, MNC=15), then:
IMPI is: 234150999999999@ims.mnc015.mcc234.3gppnetwork.org
IMPU is: " sip:234150999999999@ims.mnc015.mcc234.3gppnetwork.org "
HDN is: ims.mnc015.mcc234.3gppnetwork.org
But, HDNims.mnc＜the MNC that derives by the above-mentioned derived rule that provides in the prior art〉.mcc＜MCC〉.3gppnetwork.org can only identify this user's home-operator, when this operator had only a home domain, the IMS client necessarily belonged to this HDN; When this user's home-operator has a plurality of home domain, then can't determine user's home domain by above-mentioned derived rule.
Prior art two is at the problem of prior art one, and the home domain that the initial IMS client is obtained by derived rule is called former home domain; P-CSCF at first sends register requirement according to this former home domain, the network equipment of former home domain store IMSI number of the user and HDN between corresponding relation, obtain the home domain corresponding according to this corresponding relation with the IMS client; Then, the network equipment of former home domain is transmitted the register requirement of IMS client to the I-CSCF of home domain, and finishes the registration of IMS client.
But, in the scheme that prior art two provides, when the IMS client inserts the IMS network at every turn, all needing to send register requirement to real home domain by former home domain, access procedure is loaded down with trivial details; And the IMS client can't be known self real affiliated home domain, need provide the IMS of local home domain information business thereby can't use easily.
Summary of the invention
