Method and user equipment for ue route selection policy (ursp) rule matching type

A method for UE route selection policy (URSP) rule matching regarding S-NSSAI and PDU session type is proposed. When an application is executed, a UE finds an RSD of a matching URSP rule, and the association of the application with an existing PDU session should have some exceptions. In one example,...

description A method for UE route selection policy (URSP) rule matching regarding S-NSSAI and PDU session type is proposed. When an application is executed, a UE finds an RSD of a matching URSP rule, and the association of the application with an existing PDU session should have some exceptions. In one example, regarding S-NSSAI, if there's only a single allowed S-NSSAI or the UE is aware of the default S-NSSAI, the UE can associate the PDU session with the application where the existing PDU session is established with an S-NSSAI provided by the UE, but the RSD doesn't include any S-NSSAI. In another example, regarding PDU session type, the PDU session type IPv4v6 in the RSD can match with PDU session type IPv4 or IPv6 of the PDU session, which was established when the UE requested IPv4v6 during the PDU session establishment.
