Method, device, system and terminal for call rejecting and forwarding

Abstract

The embodiment of the invention relates to a method, a device, a system and a terminal for call rejecting and forwarding. The method for call rejecting and forwarding comprises the following steps of: receiving a call request from a calling terminal, and transmitting the call request to a called terminal; receiving a reject response message of the called terminal to the call request, wherein the reject response message carries reject processing indication information; analyzing the reject processing indication information to acquire a reject service type, and inquiring whether the called terminal registers a reject service corresponding to the reject service type; if so, carrying out corresponding service treatment according to the reject service type. If the called party is inquired to register the call reject forward, the method, the device, the system and the terminal for call rejecting and forwarding can forward the call of busy tone which is caused by the rejection of the called party, therefore, the demands of users can be satisfied.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a method, device, system and terminal for call rejection transfer. Background technique [0002] With the development of communication technology and the renewal of networks, Next Generation Network (NGN) is a new communication network based on Internet Protocol (Internet Protocol, IP), which can carry voice, data, multimedia and other services. It is a distributed, carrier-class, end-to-end unified network built on the basis of a single packet switching network, using softswitch technology, various application servers and media gateway technologies. NGN brings together fixed, mobile, broadband and other networks, and is committed to the perfect intercommunication with the Public Switched Telephone Network (PSTN) and mobile networks. At the same time, NGN provides an open system architecture, which facilitates the rapid development and deploy...

Problems solved by technology

[0003] In the era of softswitches, all kinds of terminals can be set with rejection buttons, which can reject incoming calls at any time, but softswitch devices cannot make calls when the network is busy when the user is really busy and when the user rejects the call. Handover is treated differently. The softswitch device can apply the call forwarding service when the network is busy, but the softswitch device can only use it as the call forwarding service according to the busy signaling sent by the user when the user is busy. Therefore, it cannot meet the needs of users
