Title:
SESSION MANAGEMENT METHOD AND DEVICE FOR USER GROUPS
Document Type and Number:
WIPO Patent Application WO/2020/034976
Kind Code:
A1
Abstract:
Provided by embodiments of the present application are a session management method and device for user groups. The method comprises: a session management network element receiving a first message sent by a mobility management network element, the first message carrying an identification of a first terminal and an identification of a user group, the first message being used to request to establish a session of the user group corresponding to the identification of the user group for the first terminal; the session management network element generating a routing and forwarding policy for the first terminal according to the identification of the user group; and the session management network element sending a second message to a user plane network element, the second message being used to inform the user plane network element to establish a first session for the first terminal, and the second message carrying the routing and forwarding policy. The present method implements the routing of communication between terminals in a user group within a 3GPM network without relying on the deployment and participation of external application servers.
