摘要：
A network node (26, 400) is configured for use in a wireless communication network (10). The network node (26, 400) receives a request to establish a session (14-1) for a device (12-1) in a group (18), e.g., a 5G Local Area Network group (18). The network node (26, 400) determines a user plane security policy (24-1) for the session (!4-1), based on a user plane security policy (28) for the group (18). The user plane security policy (28) for the group (18) may specify a policy for securing a user plane path of a session for any device in the group (18). The network node (26, 400) may then transmit, to an access node of the wireless communication network (10), control signaling indicating the determined user plane security policy (24-1).
