Embodiment Construction

[0072] The basic idea of ​​the present invention is that when the S-CSCF sends a user data configuration request marked as initial registration, and receives a failure response sent by the HSS that the cause of the failure is "inconsistent state", the S-CSCF re-initiates the HSS with the identification refresh registration user data configuration request.

[0073] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0074] Figure 4 This is the flow chart of the user registration method of the IMS network according to the embodiment of the present invention; in this embodiment, the S-CSCF successfully implements the refresh registration of the user by initiating two user data configuration requests to the HSS, which specifically includes the following steps:

[0075] S401 to S407 are the same as steps S301 to S307, respectively.

[0076] S408 to S409, after receiving the user data configuration request sent by...

Abstract

The invention provides a user registration method for an IP multimedia subsystem network. The method comprises the following steps that: after S-CSCF receives a registration request of a user, if judging that the user is unregistered currently, the S-CSCF sends a user data configuration request carrying an initial registration mark to HSS; after receiving a user data configuration failure responseof which the failure reason is the inconsistent state and which is returned by the HSS, the S-CSCF sends the user data configuration request carrying a refresh registration mark to the HSS; and afterreceiving a user data configuration success response returned by the HSS, the S-CSCF completes following user registration operations. The method solves the problem that when the user initiates the refresh registration in the conditions that the user data are lost due to restarting or fault of the S-CSCF or the user data do not exist when the S-CSCF is reselected, the user cannot successfully complete the refresh registration due to inconsistent user registration states of the S-CSCF and the HSS.

Description

technical field [0001] The present invention relates to the field of communications, 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 The network element entities and their connection relationships related to the present invention in the IMS architecture are described. in: [0003] User Equipment (User Equipment, UE for short) 101 represents the terminal equipment used by the user; [0004] The Call Session Control Function (CSCF for short) is the core network element that controls the session process, including: Proxy-CSCF (P-CSCF for short) 102, Interrogating-CSCF (Interrogating-CSCF) , referred to as I-CSCF) 103, Serving Call Session Control Function (Serving-CSCF, referred to as S-CSCF) 104; [0005] Home Subscriber Server (HSS for short) 105 i...
