Problems solved by technology

[0002] At present, there is no SIP protocol-based call barge implementation scheme in the softswitch system. The similar service is call access waiting, but this service is the called side service. In the relevant service specifications of the softswitch and the SIP protocol specification, There is no definition of a method for implementing the forced insertion service based on the SIP protocol standard. In daily work and life, users often need to notify the called party in time when there is an emergency, and the called party may be in a long-term non-important During the call, it affects the transmission of important matters of the calling party. For example, user A calls user B, and user B is in the communication state with user C. The system provides user A with a voice prompt, indicating that user B is in the communication state and the system is connecting. , if you need to continue the connection, press a certain key, otherwise you can choose to hang up, after a period of time, user B is still busy, and the system will keep repeating this prompt process
[0003] In addition, for the forced insertion service in the traditional digital switching system, the system directly performs the forced insertion and forced removal, without allowing the user to choose whether to force the insertion or not, and there is no friendly voice prompt, which is relatively rough and the user experience is not good. The implementation of plug-in service, the business process is as follows: user A calls user B, user B is in the communication state with user C, the system detects that user B is in the communication state, releases the forced demolition of user C, and simultaneously connects user A and user B , not very friendly
[0004] In the call waiting service of the existing softswitch service, when the called party is busy, the authority to connect the new call is on the called side. Unable to communicate with the called party in time

Embodiment Construction

[0032] The technical solution of the present invention is further described below in conjunction with the examples, but the scope of protection is not limited to the description.

[0033] Such as figure 1 , a kind of SIP user forced insertion service realization method based on softswitch, it comprises the following steps:

[0034] (1), user B and user C establish a call through the call server CS, and are in a conversation state;

[0035] (2) The CS receives an INVITE session request from user A calling user B with intrusion authority, and initiates an INVITE session request to user B;

[0036] (2) During the process of waiting for the response from user B, when the CS receives the 486 response from user B, it sends an ACK message to user B. At the same time, the CS detects that user A has the intrusion service authority, and then triggers the call intrusion broadcast service;

[0037] (3), CS sends btmc_ivr_pc_req request message to media server MS, requests MS to play pro...

Abstract

The invention discloses an SIP user forced insertion service achievement method based on soft exchange. A user B and a user C are under a calling state, a CS receives an INVITE conversation request that a user A with a forced insertion privilege calls the user B, the INVITE conversation request is launched to the user B, media streams of an MS and the user A are built, ultimately the user A and the user B are in a conversation state, and forced insertion service of the user A is achieved. The method has the advantages that forced insertion and forced releasing services of SIP users are achieved on the basis of SIP protocol signaling; under the condition that a called party is busy, the user with the forced insertion privilege can select forced insertion calling so that the user can communicate with the called party in time, in the service process, a calling user can select whether to carry out forced insertion calling, when the calling user selects the forced insertion calling, the system can play a voice prompt for the calling user and the called user, experience of the users is good and user experience is improved.

Description

technical field [0001] The invention relates to a method for realizing a SIP user forced insertion service based on a soft switch, and belongs to the technical field of network communication. Background technique [0002] At present, there is no SIP protocol-based call barge implementation scheme in the softswitch system. The similar service is call access waiting, but this service is the called side service. In the relevant service specifications of the softswitch and the SIP protocol specification, There is no definition of a method for implementing the forced insertion service based on the SIP protocol standard. In daily work and life, users often need to notify the called party in time when there is an emergency, and the called party may be in a long-term non-important During the call, it affects the transmission of important matters of the calling party. For example, user A calls user B, and user B is in the communication state with user C. The system provides user A wi...
