[0073] Figure 4 It is a flow chart of the user registration method of the IMS network in the first embodiment of the present invention; in this embodiment, the HSS independently solves the problem of inconsistency in user registration status, and is applicable to the restart and failure recovery of the S-CSCF serving the UE, or reselection for the UE In the case of S-CSCF, the specific steps are as follows:

[0074] S401~S407, same as steps S301~S307;

[0075] S408-S409, after receiving the user data configuration request sent by the S-CSCF, the HSS recognizes the initial registration identifier in the request (that is, the value of Server Assignment Type is REGISTRATION, or the registration status of the user is Not Registered) , and the registration status of the user recorded locally is Registered; in this case, the HSS does not return a user data configuration failure response, but includes the user's subscription data and billing address information in the user data con...

[0080] Figure 5 It is a flow chart of the user registration method of the IMS network in the second embodiment of the present invention; in this embodiment, the S-CSCF carries a special mark (may be referred to as a user data unavailable mark) in the user data configuration request to notify the HSS that there is no available user locally Data, HSS is required to solve the problem of inconsistent user registration status. The special flag carried in the user data configuration request can be: restart or failure recovery label: used to identify the user data that is unavailable after the S-CSCF allocated to the UE restarts or fails. ; or reselection label: used to indicate that the S-CSCF that previously served the UE is unavailable, and the I-CSCF has reselected a new S-CSCF for the UE; this embodiment is also applicable to the restart and failure of the S-CSCF serving the UE Recovery, or the case where the S-CSCF is reselected for the UE; specifically, the following steps ar...

Abstract

The invention discloses a user registration method for an IP multimedia subsystem network, which comprises the following steps that: when receiving a user data collocation request which is sent by a service call session control function S-CSCF and carries an initial registration mark and finding through locally recorded information that the registration state of the user is registered, a home subscriber server HSS sends user data collocation response back to the S-CSCF. The method of the invention applies to an IP multimedia subsystem and solves the problem that a user cannot refresh and register due to the inconsistent user registration states in the S-CSCF and the HSS when the user initiates refreshing and registration under the condition of user data loss caused by S-CSCF restart or a failure or no user data when S-CSCF is reselected.

Description

technical field [0001] The invention relates to the communication field, in particular to a user registration method for an IP (Internet Protocol, Internet Protocol) multimedia subsystem network. Background technique [0002] The IP Multimedia Core Network Subsystem (IMS for short) is the core of the new generation communication network. figure 1 Describes the network element entities and their connections in the IMS architecture related to the present invention. in: [0003] User Equipment (UE for short) 101 represents a terminal device used by a user; [0004] The call session control function (Call Session Control Function, referred to as CSCF) is the core network element that controls the session process, including: proxy call session control function (Proxy-CSCF, referred to as P-CSCF) 102, interrogating call session control function (Interrogating-CSCF , I-CSCF for short) 103, Serving-CSCF (Serving-CSCF, S-CSCF for short) 104; [0005] Home Subscriber Server (HSS f...
