Abstract: A method for route selection policy (URSP) rule matching enhancement in EPS is proposed. When an application is executed, the upper layer of a UE sends the application information to URSP entity for matching a URSP rule. The UE selects and evaluates a route selection descriptor (RSD) from a list of RSDs of a selected URSP rule to be matched with a PDN connection. If there is a “PDU session pair ID type” and/or “RSN type” route selection descriptor components in an RSD, such RSD components are intended for a redundant PDU session, which is not supported in EPS. Therefore, the UE ignores the specific RSD components and continues to evaluate the RSD with the remaining RSD components.
