The register method of opening an account that fixed-line subscriber provided by the present invention is linked into the IMS territory comprises the step of " user opens an account " and " initiating registration ", and is specific as follows:
At first, in " user opens an account " step, specifically, under the IMS framework, all users must be assigned with a user ID, and this user ID comprises IP multimedia private identity (Private user identity) and IP multimedia pUblic identity (Public user identity), i.e. PVI and PUI.At first each user has obtained several users public identify PUI, is called the Subscriber Number collection.User PVI generates at random or generates according to the Subscriber Number collection, but it will keep uniqueness.
When the user opened an account, counter write following data in HSS: user PVI, user PUI, this locality of user (Home) domain name Id.The corresponding relation of user PVI and PUI.User's Home domain name Id can adopt the form of numeral, is called domain name Id.
Then, in the step of " initiating registration ", promptly initiate in the step of registration to ownership IMS territory by AGCF the user, specifically, the user initiates registration by AGCF to ownership IMS territory, and as shown in Figure 2, concrete registration step is described below:
Step S1: the user initiates registration by AG notice AGCF;
Step S2:AGCF sends registration message SIP-Register to enquiry call conversation control function entity I-CSCF (Interrogating-CSCF);
Step S3:I-CSCF sends query messages Cx_query/Cx_Select_pull to HSS;
Step S4:HSS returns the S-CSCF address of user attaching to I-CSCF;
Step S5:I-CSCF sends registration message SIP-Register to the S-CSCF of ownership;
Step S6: the S-CSCF of user attaching initiates registration to HSS;
Step S7:HSS returns registering result to the S-CSCF of ownership, and following slotting user data is to S-CSCF;
Step S8: based on filter criteria, S-CSCF sends log-on message SIP-Register to PES APP,
And execution corresponding business control procedure;
Step S9: simultaneously, S-CSCF returns the message 200OK to I-CSCF that succeeds in registration;
Step S10:I-CSCF returns the message 200OK to AGCF that succeeds in registration;
Step S11:AGCF echo reply message Reply to AG, and registered user's state is changed to " online ".
The present invention is according to the open an account situation of registration of actual user, and registration scenarios is divided into 1, dynamic registration situation and 2, forces online two kinds of situations.And dynamic registration can be divided into: (1) unique user registration (2) is three kinds of situations of user's registration (3) territory registration in batches.
Wherein, the performing step of the unique user registration in the dynamic registration mode can be divided into a again, and two kinds of execution modes of b below in conjunction with Fig. 2 and Fig. 3, are done a step to the unique user register flow path and described.
As shown in Figure 2, unique user registration execution mode a specific implementation step is as follows:
201. when AG powered on, AG passed through Service Change message H.248, notice AGCF initiates registration;
202.AGCF each user is initiated register flow path, sends the SIP-Register registration message to I-CSCF;
