Network node and a method in a wireless communications network

Abstract

A method performed by a network node for managing an Internet Protocol, IP, flow in a User Plane, UP, session to be boosted on request by an Application Function, AF, node for a User Equipment, UE, in a wireless communications network is provided The network node obtains (201) from a first Core Network, CN, node, information identifying UP sessions that are available to the UE, based on a subscriber identifier of a user of the UE. The network node determines (202), based on configuration data received from a second CN node, whether boost is allowed for a particular UP session among the identified UP sessions. When it is determined that boost is allowed in the particular UP session, the network node determines (203) a source IP address for the particular UP session. The network node requests (204) from the second CN node, boost of the IP flow identified by the source IP address as determined, and a destination IP address and port comprised in information obtained from the AF node. The network node configures (205) in the second CN node, a Policy and Charging Control, PCC, rule to the identified IP flow for the particular UP session where boost is determined to be allowed.
