1. A method for a policy control function (PCF) of a communication network, the method comprising:
during establishment of a packet data unit (PDU) session for a user equipment (UE), determining one or more UE application descriptors that correspond to a network application identifier, AppId, of a service data flow (SDF) template for the PDU session, wherein each UE application descriptor includes:
a first identifier, OSId, of a UE-supported operating system (OS), and
a second identifier, OSAppId, of an application for the UE-supported OS identified by the first identifier;
receiving a request for policy rules for the PDU session from a session management function (SMF) of the communication network, wherein the request includes the SDF template which includes the network application identifier, AppID; and
in response to the request, sending the policy rules for the PDU session to the SMF, wherein the policy rules sent to the SMF include the UE application descriptors that correspond to the network application identifier, AppID.
