Abstract: 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.

Abstract: Embodiments of the present invention provide a service processing method and device. The service processing method includes: receiving a first message, where the first message includes first information of a first network slice, a priority corresponding to the first information, second information of a second network slice, and a priority corresponding to the second information; and preferentially processing a service of the high-priority network slice based on the priorities when a service of the first network slice collides with a service of the second network slice.

Abstract: This application provides a data route selection method and apparatus, and relates to the field of communications technologies, so as to resolve a problem of an excessively long transmission delay for an application program that initiates a data transmission request relatively later. The data route selection method includes: detecting, by a terminal, that information about an application matches a traffic descriptor; determining, by the terminal, a first route selection components for the application; and routing, by the terminal, traffic of the application on a first protocol data unit PDU session. The first PDU session matches the first route selection components. This application is applicable to a terminal.

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.
