Embodiment Construction

[0049] Since the P-CSCF has the ability to identify whether the message sent by the user equipment is a logout request message initiated by the emergency PUI, it can be directly identified by the P-CSCF after the logout request message initiated by the user equipment is sent to the P-CSCF The message is output, a failure response is constructed and sent to the user device. In this way, the logout request message initiated by the emergency PUI is prevented from continuing to propagate on the network, and network resources are saved.

[0050] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0051] Such as image 3 As shown, the processing method of the logout request message initiated by the emergency public user identity of the present...

Abstract

The invention discloses a method for processing a logout request message which is originated by an IP multimedia subsystem with the identification of an emergency public user, a device and a system thereof. The method comprises: firstly, recognizing whether a message is the logout request message which is originated with the identification of an emergency public user or not after a P-CSCF receives the message sent by a user device, continuing to send the message to an I-CSCF for post processing if the message is not the logout request message which is originated with the identification of an emergency public user, and directly constructing a failure response message and sending the message to the user device if the message is the logout request message which is originated with the identification of an emergency public user, and the message is not transmitted any more, thereby the processing flow is saved, network resources are saved, and the network burden is alleviated.

Description

technical field [0001] The present invention relates to the field of communication technology, and more specifically, relates to a method and device for processing a logout request message initiated by an emergency public user identity (Public User Identity, PUI) by an IP (Internet Protocol, Internet Protocol) multimedia subsystem and system. Background technique [0002] The IP Multimedia Core Network Subsystem (IMS) is implemented based on the SIP protocol (Session Initiation Protocol, a session initiation protocol, an application layer protocol that creates, modifies, and terminates sessions between two or more parties). The CSCF (Call session Control Function) in the IP multimedia subsystem is used to complete registration, session, and session-independent functions. [0003] The emergency PUI is formed after the IMS user adds an emergency flag to the PUI, which is different from the normal PUI. For example: add the emergency or sos flag at the beginning of the PUI dom...
