Problems solved by technology

According to this serial mode, the more services a user subscribes to, the more ASs that a call request passes through, resulting in an increase in call delay, and once one of the ASs is abnormal, the call flow may be affected

Embodiment Construction

[0049] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0050] figure 2 It is a schematic flow diagram of the SSCCF side method of the SIP message interaction method in the IMS network according to the embodiment of the present invention, as shown in figure 2 The method for SIP message interaction in the shown IMS network includes:

[0051] S100, receiving an initial SIP message in any call, matching an initial AS according to the initial SIP message, and triggering the initial SIP message to the initial AS;

[0052] Specifically, the matching to the initial AS according to the initial SIP message means matching to the initial AS according to the IFC subscribed by the user in the initial SIP message.

[0053] S101. Receive...

Abstract

The invention provides an SIP message interaction method, device and equipment in an IMS network. The method comprises the following steps: receiving an initial SIP message in any call, matching to aninitial AS according to the initial SIP message, and triggering the initial SIP message to the initial AS; receiving a processed SIP message returned by the initial AS, wherein the processed SIP message is an SIP message processed according to the initial SIP message; if it is detected that the processed SIP message carries a message for forbidding subsequent triggering; if yes, recording a message list of any call forbidding follow-up triggering, the message forbidding follow-up triggering being used for indicating SIP messages forbidding triggering in the follow-up SIP messages of any call,including a message list forbidding follow-up triggering or a message list index forbidding follow-up triggering. The message flow can be simplified, the call delay can be shortened, and the fault risk can be reduced.

Description

technical field [0001] The present invention relates to the field of communication core network, and more specifically, relates to a method, device and equipment for SIP message interaction in an IMS network. Background technique [0002] VoLTE (Voice over LTE) is the target solution of mobile operators' 4G voice basic service plan, providing IP voice services based on the packet domain. For VoLTE, IMS provides call control and service logic, EPC provides high-quality packet domain bearer, and eSRVCC ensures call continuity before continuous coverage. [0003] A call session control function (Call Session Control Function, CSCF) is an internal functional entity of an IP Multimedia Subsystem (IMS: IP Multimedia Subsystem), and is the core of the entire IMS network. It is mainly responsible for handling the signaling control during the multimedia call session. CSCF is divided into Proxy CSCF (P-CSCF: Proxy CSCF), Inquiring CSCF (I-CSCF: Interrogating CSCF), Serving CSCF (S-C...
