Network handover method, terminal, controller, gateway, and system

A network handover method, a terminal, a controller, a gateway, and a system. The method includes: when a terminal accesses a first network, converting data including an initial TCP four-tuple into data including a first TCP four-tuple, and sending the data to a gateway; and after handing over from the first network to a second network, converting data including the initial TCP four-tuple into data including a second TCP four-tuple, and sending the data including the second TCP four-tuple to the gateway. This achieves objectives of preventing a connection from being interrupted before and after the network handover, improving use experience, and reducing complexity of a network handover process.

Network slice support of respective transport protocols

Techniques are described herein for network slice support of respective transport protocols. In one example, a session management function obtains, from a user equipment, a request for a network slice identifier in a network that includes a plurality of network slices each configured to support a respective transport protocol. In response to the request, the session management function identifies a first transport protocol of the respective transport protocols by which the user equipment is to communicate. Based on the first transport protocol, the session management function identifies a first network slice of the plurality of network slices by which the user equipment is to communicate. The first network slice is configured to support the first transport protocol. The session management function provides the network slice identifier to the user equipment. The network slice identifier corresponds to the first network slice.
