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 user data configuration failure response sent by the HSS because the failure reason is "inconsistent status", it re-initiates to the HSS marked as a refresh registration User data configuration request for .

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

[0074] Figure 4 It is a flow chart of the user registration method of the IMS network in the embodiment of the present invention; in the present embodiment, the S-CSCF initiates two user data configuration requests to the HSS to successfully realize the refresh registration of the user, specifically including the following steps:

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

[0076] S408-S409, after receiving the user data configuration request sent by the S-CSCF, the HSS recogniz...

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 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...
