Abstract:
The present invention discloses a method, a system, a terminal, an MSC server, and an SCC application server for transferring a video call between access networks. The method includes: pre-negotiating, in a PS domain and through IMS signaling, a CS video call parameter; and, after a video call of a terminal is transferred from the PS domain to a CS domain, establishing a CS video call according to the pre-negotiated CS video call parameter. By using the technical solutions of the present invention, the CS video call parameter is pre-negotiated before the video call of the terminal is transferred from the PS domain to the CS domain, and after transfer to the CS domain, the CS video call is established by directly using the pre-negotiated CS video call parameter.
