USER-PLANE PROTOCOL STACK DETERMINING METHOD, CONTROL-PLANE NETWORK ELEMENT, AND SYSTEM

摘要

The present disclosure relates to a user-plane protocol stack determining method, a control-plane network element, and a system. The method includes: obtaining attribute information of a service of a terminal; determining, based on the attribute information of the service, a user-plane protocol stack used to transmit the service, and determining a user-plane network element serving the terminal; and sending protocol stack type indication information of the user-plane protocol stack to the user-plane network element and an access-network network element, where the protocol stack type indication information is used to indicate the user-plane protocol stack corresponding to the user-plane network element and the access-network network element. Therefore, a to-be-used user-plane protocol stack is determined according to different service requirements of the terminal, thereby flexibly meeting the service requirements of the terminal.
