Abstract

The invention is applicable to the technical field of short-wave communication, and provides a SIP-based call enhancement control method, which includes a timeout forwarding control step, a forced demolition and forced insertion control step, and a private network user call step. The command user has registered multiple phone numbers. If the command user calls the phone number and the command user does not answer after timeout, it will forward to the next registered number until all the phone numbers are tried; when the on-site user establishes a call connection with the command user, there will be Another command user needs to call the on-site user, and the forced removal and insertion operations are performed according to the priorities of the two command users to meet the call needs of high-priority command users and on-site users; in addition, private network user calls can also be realized. The technical scheme of the invention can flexibly perform call control according to the user's requirements, and satisfy various service demands of the commanding user and the on-site user.

Description

technical field [0001] The invention belongs to the technical field of shortwave communication, in particular to a SIP-based call enhancement control method. Background technique [0002] The SIP protocol (Session Initiation Protocol, Session Initiation Protocol) is a multimedia communication protocol formulated by the IETF (Internet Engineering Task Force, Internet Engineering Task Force). It is a text-based application-layer control protocol for creating, modifying, and releasing sessions with one or more participants. [0003] The SIP protocol is generally only applicable to the simple two-party call establishment process. In the actual call process between the two parties, there will be some special situations, such as one user not answering after timeout, multiple users calling a user, calling a private network user, etc., the SIP protocol is Out to the relevant call control, can not adapt to the exchange of integrated services in the short-wave communication network. ...
