Communication call forwarding device and method based on IMS system

Abstract

The invention discloses a communication call forwarding device and method based on an IMS system, and the device comprises a communication terminal and an IMS communication system connected with the communication terminal, and the IMS communication system is connected with IMS system special service number equipment, IMS system maintenance equipment, and an IMS system user database. After communication is established between the communication terminal and the IMS system special service number equipment, call forwarding conditions and call forwarding numbers set through IVR voice navigation, and the calling number and the called number of the communication terminal are stored in an IMS communication system database; and when the calling number of the communication terminal dials the callednumber, the IMS communication system detects the state of the called number and completes the communication connection between the calling number and the call forwarding number according to the call forwarding condition and the call forwarding number set by the called number. The communication call forwarding device and method solve the problem of offline call forwarding which does not exist in awired fixed network communication environment, provide a mobile communication and fixed wired communication unified standard call forwarding method, and solve the problem that videos and messages cannot be forwarded.

Description

technical field [0001] The invention belongs to the technical field of network communication, and relates to an IMS system-based communication call transfer device and method. Background technique [0002] The call transfer function of communication plays a very important role in safe production, office and life. At present, there are two specifications for call transfer: one is fixed network communication call transfer. Fixed-line communication call transfer is based on program-controlled switching technology, and the unified operation standard of call transfer is as follows: 1) All transfer: After setting, all incoming calls will be transferred to the preset fixed telephone or other information tools immediately; the implementation method is: Press "*57*number#" on the fixed line, cancel method: press "#57#" on the fixed line; If you do not set call forwarding on no answer, this phone will also be regarded as busy call forwarding when you refuse to answer; implementation ...
