Abstract

A kind of NGN call transfer method and system related to electric communication technology, comprising the following steps: A, when the user is called, NGN softswitch center sends call start instruction to call transfer service server, B, call transfer service server according to call transfer process And corresponding call transfer strategy, after carrying out corresponding operation or operation, send corresponding policy operation command to NGN soft switch center; C, NGN soft switch center controls corresponding terminal to carry out order; Before described step A, the user calls transfer service Call transfer strategy is set in the server, the binding of temporary phone number and registered phone number and its enablement; Described call transfer strategy is the combination of transfer condition and concrete strategy operation, the present invention has reduced the burden of NGN softswitch center, has improved System efficiency and strong practicability.

Description

technical field [0001] The present invention relates to electric communication technology, in particular to an NGN call transfer method and system. Background technique [0002] Next Generation Network (NGN: Next Generation Network) is a comprehensive and fully open network architecture that can provide multiple services such as voice, data, and multimedia at the same time, and can realize gigabit optical fiber broadband to equipment terminals. It is based on Grouped networks can provide telecommunication services, for example, by providing intelligent call transfer to realize telephone call management for users, that is, users can set their terminal phone calls to be forwarded to other numbers when the call is timed out or busy, from In a sense, intelligent call transfer is a remedy for the inability to directly establish a call with a calling number. However, in the existing call transfer control, call control and call transmission are both completed by NGN core equipment....
