Mobile-terminated packet transmission

An apparatus, comprising:

• a memory;
• and
• processing circuitry in communication with the memory, wherein the apparatus is comprised in a control plane device configured to operate within a packet network core connected to a user equipment (UE) via a radio access network, and wherein the processing circuitry is arranged to:
• configure a routing policy on one or more data gateways for a service flow of a service for the UE;
• and
• perform a notification procedure towards one or more application functions via a Service interworking function in response to the configuration of the routing policy, wherein the notification procedure is based on a previous notification request from the one or more application functions via the Service interworking function requesting notification of changes.

A method, comprising:

• while a packet network core is connected to a user equipment (UE) via a radio access network:
• configuring a routing policy on one or more data gateways for a service flow of a service for the UE;
• and
• performing a notification procedure towards one or more application functions via a Service interworking function in response to the configuration of the routing policy, wherein the notification procedure is based on a previous notification request from the one or more application functions via the Service interworking function requesting notification of changes.

A non-transitory computer readable memory medium, comprising:

• program instructions configured to cause a control plane device operating within a packet network core connected to a user equipment (UE) via a radio access network to:
• configure a routing policy on one or more data gateways for a service flow of a service for the UE;
• and
• perform a notification procedure towards one or more application functions via a Service interworking function in response to the configuration of the routing policy, wherein the notification procedure is based on a previous notification request from the one or more application functions via the Service interworking function requesting notification of changes.
