Description
Technical field
The present invention relates to field of communication technology more particularly to a kind of call forwarding methods and device.
Background technology
With the fast development of broadband network, the application of broadband services becomes increasingly complex.NGN(Next Generation
Network, next generation network) do not limit in network or IMS (IP Multimedia System, IP multimedia system) network before
In the operation flow for turning number, forward must once trigger a business scenario, business again outgoing call in core net.
In existing call forwarding method, as terminal A calling terminal B, terminal A passes through the call signaling of calling terminal B
It crosses the intermediate NEs such as proxy server (Proxy Server) and/or core net and is sent to terminal B；When terminal B receives calling
During signaling, if need to carry out Call Forwarding to other-end according to preset contextual model rule, terminal A is needed to pass through generation
The intermediate NEs such as reason server (Proxy Server) and/or core net resend call signaling to other-end.At this
In the process, the call signaling in operation flow is intermediate by multiple proxy servers (Proxy Server) and/or core net etc.
Network element, the intermediate NE that signaling is passed through is excessive, and the out of order of signaling and loss equiprobability is caused substantially to increase, and reduces realization
