Problems solved by technology

However, because the IMS registration timer has not expired, the user remains registered in the IMS domain, resulting in inconsistent user status in the CS domain and the IMS domain, and subsequent user registration and session services in the IMS domain cannot be realized.

Embodiment Construction

[0065] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0066] The present invention provides a mechanism for the CS domain and the IMS domain to actively negotiate the registration timeout time when the CS user registers or re-registers in the IMS domain, and the content of the invention is as follows:

[0067] FIG. 4A shows a registration timeout negotiation method according to the present invention. As shown in Figure 4A, when a CS user registers or re-registers in the IMS domain, the mechanism for the CS domain and the IMS domain to actively negotiate the registration timeout period includes the following steps:

[0068] Step S402A, after the user successfully updates the CS domain location, the local CS domain access adaptation function entity initiates a registration or re-registration request to the IP Multimedia Subsystem on the CS domain session control path, and the registrat...

Abstract

The present invention provides a registration timeout negotiation method, a logout and user separation method, a re-registration method and a logout method, wherein, the registration timeout negotiation method includes three steps: (S402) After the update of the CS (Circuit Switched) domain position of a user succeeds, a LCAAF (Local CS Access Adaptation Function) entity sends a registration or re-registration request message to an IMS (IP Multimedia Subsystem) via a CS session control path, and the registration or re-registration request message carries the update time of the CS domain position; (S404) According to the update time of the CS domain position and a local policy, a CSCF (Call Session Control Function) entity in the IMS sets a registration timeout; (S406) The CSCF entity sends a registration or re-registration success response message containing the registration timeout to the LCAAF entity.

Description

technical field [0001] The invention relates to the communication field, in particular to a registration overtime negotiation method, a logout and user separation method, a re-registration method, and a logout method. Background technique [0002] IP (Internet Protocol, IP for short) multimedia subsystem (IPMultimedia Core Network Subsystem, IMS for short) is an IP-based network architecture proposed by the 3rd Generation Partnership Project (3GPP for short). It builds an open and flexible business environment, supports multimedia applications, and provides users with rich multimedia services. [0003] IMS is an IP-based telecommunications network architecture and has nothing to do with access technology, except that it can be used for packet switching (PacketSwitched, PS) In addition to providing services for the access network, it can also provide services for mobile cellular networks such as GSM (Global System for Mobile communications, Global System for Mobile Communica...
