Abstract

A method for UE route selection policy (URSP) rule matching is proposed. URSP is used by a UE to determine if a detected application can be associated to an established PDU session, can be offload to non-3GPP access outside a PDU session, or can trigger the establishment of a new PDU session. The UE first finds a non-default URSP rule with a matching traffic descriptor to the application. When the UE fails to find existing PDU session or setup new PDU session with any or the route selection descriptors of the non-default URSP rule, the UE moves to another non-default URSP rule, if any, and try the matching. If all non-default URSP rules cannot be matched with the application, then the UE tries the default URSP rule, which includes a match-all traffic descriptor.
