摘要
The embodiments herein relate to Sx protocol extension to support node PDR. In one embodiment, there proposes a method (500) in a first network node (301) configured as control plane function (CPF). The first network node (301) is coupled to a second network node (302) configured as user plane function (UPF) via an Sx interface. The method (500) comprising transmitting (S501) a message associated with a Packet Detection Rule (PDR) to the second network node (302) via the Sx interface, wherein the PDR is applicable to more than one Sx session. With embodiments herein, the CPF-UPF signaling throughput can be minimized significantly, and the memory footprint per Sx session can be decreased.
