摘要： An inter-network change method and apparatus, where a terminal determines second network slice information to which first network slice information is mapped. The first network slice information is information about a first network slice accessed by the terminal, the second network slice information is information about a second network slice, the first network slice is a network slice in a first network, and the second network slice is a network slice in a second network. The terminal sends a request message to the second network and receives an accept message returned by the second network, such that the terminal accesses a network slice identified by network slice information accepted by the second network. It can be learned that embodiments of the present disclosure can implement a handover operation between network slices of different networks.

摘要： 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.
