Methods, apparatus and computer-readable mediums supporting subscriptions to events in a core network

A method in a policy control function (PCF) for a core network of a wireless cellular network, the method comprising:

• the PCF receiving, from a network exposure function (NEF), a subscription request message to subscribe to event reporting, wherein
• the subscription request message comprises 1) targeting information indicating a target of the event reporting, wherein the targeting information comprises i) an indicator indicating that any user equipment (UE) is targeted for a specific Data Network Name and network slice or ii) a UE group identifier identifying group of UEs and 2) a first indication indicating one or more types of resources for which the subscription will apply, and the first indication included in the subscript request message indicates that the subscription applies to dynamically allocated resources.

A network exposure function apparatus for a core network of a wireless cellular network, the network exposure function apparatus comprising processing circuitry and a non-transitory computer-readable medium storing instructions which, when executed by the processing circuitry, cause the network exposure function apparatus to:

• provide, to a policy control function for the core network, a subscription request message to subscribe to event reporting, wherein
• the subscription request message comprises 1) targeting information indicating a target of the event reporting, wherein the targeting information comprises i) an indicator indicating that any user equipment (UE) is targeted for a specific Data Network Name and network slice or ii) a UE group identifier identifying group of UEs and 2) a first indication indicating one or more types of resources for which the subscription will apply, and the first indication included in the subscript request message indicates that the subscription applies to dynamically allocated resources.
