Telephone call procedures for power efficient mobile terminating packet switched services

A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors to perform operations for communication by an application server comprising memory and processing circuitry coupled to the memory, the operations to configure the one or more processors to perform the following operations:

• determine a telephone number associated with a client application executing on a user equipment (UE) and store the telephone number in the memory;
• initiate a telephone call to the UE associated with the client application via a cellular access network node according to the telephone number;
• receive a first set of data via a packet data network (PDN) including the cellular access network node from the client application, the first set of data including an Internet protocol (IP) address for communication with the client application;
• determine a PDN communication channel associated with the client application according to the received first set of data and the IP address;
• and
• send a second set of data to the client application via the PDN including the cellular access network node according to the PDN communication channel associated with the client application and the IP address.

An apparatus of a user equipment (UE), the apparatus comprising memory;

• and
• processing circuitry coupled to the memory, the processing circuitry configured to:
• receive a paging for a telephone call from a cellular access network node;
• and
• in response to the received paging:
• determine a packet data network (PDN) communication channel associated with a server application executing on an application server, the PDN including the cellular access network node, and the PDN communication channel determined based on an Internet protocol (IP) address for communication with the server application;
• and
• send a set of data to the server application via the determined PDN communication channel.
