Embodiment Construction

[0030] (1) Silent operation

[0031] The following conversation flow is that the console initiates a conference call, calls terminals 02 and 03 after the server responds, then mutes terminal 02, kicks terminal 03 out of the conference, and ends the conference.

[0032] Signaling description:

[0033] 1. INVITE C$1234231 notifies the server that the next signaling with C$1234 is a conference operation.

[0034] 2. Refer-To A#02231 and Refer-To A#03231 initiate a conference call to the server and call terminals 02 and 03.

[0035] 3. Refer-To M#02231 notifies the server to mute 02 (no longer transmit voice media stream to 02).

[0036] 4. Refer-To D#03231 notifies the server to hang up the 03 session.

[0037] 5. When initiating a conference call, when the first terminal rings, it will return 180 Ringing to the console, and when the first terminal answers, it will return 200 OK to the console. In other cases, these two signalings will not be returned.

Abstract

The invention relates to an SIP realizing method for service logical combination, which performs override, break-down, forced connection and other special dispatching operations on one-party or multi-party conversation in a communication dispatching system. In the method, action operation of the conversion is firstly divided into three basic actions, namely addition, deletion and mute, by proper abstract larger-granularity division, and all service requirements of the conversation, including mute, switching, picking-up, override, break-down, forced connection and other operations, can be realized through the logical combination of the three basic actions, so that the high reusability can be realized by service logic, the development efficiency of new service logics can be improved, and the development cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to a SIP implementation method of business logic combination for one or more parties in a communication dispatching system (not limited to the dispatching system), forced insertion, forced removal, forced connection and other special scheduling operations. Background technique [0002] In traditional circuit switching, the various functions or services provided to users are directly related to the switch, and the services and control are all completed by the switch. It is completed by switch nodes, and the hardware platform is closed, which is not conducive to business development and application. Nowadays, it is necessary to separate the service from the control, and the call control from the bearer, which leads to the concept of the next generation network (NGN). The next generation network adopts an open and distributed network architecture, which divides the network into ne...
