1. A method performed by a network node which implements a Session Management Function in a 5G core network of a wireless communication network, the method comprising:
receiving, at the network node, a request to establish a session for a device in a 5G Local Area Network (5GLAN) group;
determining a user plane security policy for the session, based on a user plane security policy for the 5GLAN group, wherein the user plane security policy for the 5GLAN group specifies a policy for securing a user plane path of a session for any device in the 5GLAN group; and
transmitting, from the network node to an access node of the wireless communication network, control signaling indicating the determined user plane security policy.
