Abstract
A method for establishing a Protocol Data Unit (PDU) Session(s) is disclosed. In examples disclosed herein, a device (e.g., a wireless device) uses a unique Port Number(s) (e.g., an internal physical or logical Port Number) to search for a matching User Equipment (UE) Route Selection Policies (URSP) rule(s) having a Traffic Descriptor(s) that matches the unique Port Number(s). The device then determines whether there exists a matching PDU Session(s) associated with a Route Selection Descriptor(s) of the matching URSP rule(s). Accordingly, the device can reuse the matching PDU Session(s) in a presence of the matching PDU Session(s) or establish a new PDU Session(s) in an absence of the matching PDU Session(s). By using the unique Port Number(s) as the Traffic Descriptor(s) in the URSP rule(s), it is possible to simplify configuration of the device, especially for redundant traffic handling.
