Abstract

A method is provided in one example embodiment and may include determining that a periodic timer for a user equipment (UE) is about to expire; communicating to an application service, prior to expiration of the periodic timer for the UE, an indication associated with an availability of the UE to receive data from the application service; and communicating the data from the application service to the UE upon receiving the indication. In some cases, the method can include registering, by the application service, to receive the indication from a Mobility Management Entity (MME) or a serving General Packet Radio Service (GPRS) support node (SGSN), wherein the registering is performed via a service capability exposure function (SCEF) in communication with the MME or the SGSN and the application service.

Claims

1. A method comprising:

registering, by an application service, to receive an indication from a Mobility Management Entity (MME) or a serving General Packet Radio Service (GPRS) support node (SGSN), wherein the indication is associated with an availability of a user equipment (UE) to receive data from the application service and wherein the registering is performed via a service capability exposure function (SCEF);

determining that a periodic timer for the UE is about to expire;

communicating to the application service, prior to expiration of the periodic timer for the UE, the indication associated with the availability of the UE to receive data from the application service; and

communicating the data from the application service to the UE upon receiving the indication.

2. The method of claim 1, wherein the registering includes subscribing by the application service to an event trigger for the MME or the SGSN.

3. The method of claim 2, further comprising:

configuring a mobile reachability timer for the MME or the SGSN, where the mobile reachability timer is associated with the event trigger and the periodic timer for the UE.

4. The method of claim 2, wherein the periodic timer is associated with a Tracking Area Update (TAU) timer or a Routing Area Update (RAU) timer for the UE.

5. The method of claim 2, wherein communicating the data to the UE includes paging the UE by the MME or the SGSN to receive the data from the application service.

6. The method of claim 2, wherein communicating the data to the UE includes communicating the data to the UE without paging the UE.

7. One or more non-transitory tangible media encoding logic that includes instructions for execution by a processor, wherein the execution causes the processor to perform operations, comprising:

registering, by an application service, to receive an indication from a Mobility Management Entity (MME) or a serving General Packet Radio Service (GPRS) support node (SGSN), wherein the indication is associated with an availability of a user equipment (UE) to receive data from the application service and wherein the registering is performed via a service capability exposure function (SCEF);

determining that a periodic timer for the UE is about to expire;

communicating to the application service, prior to expiration of the periodic timer for the UE, the indication associated with the availability of the UE to receive data from the application service; and

communicating the data from the application service to the UE upon receiving the indication.

8. The media of claim 7, wherein the registering includes subscribing by the application service to an event trigger for the MME or the SGSN.

9. The media of claim 8, wherein the execution causes the processor to perform further operations, comprising:

configuring a mobile reachability timer for the MME or the SGSN, where the mobile reachability timer is associated with the event trigger and the periodic timer for the UE.

10. The media of claim 8, wherein the periodic timer is associated with a Tracking Area Update (TAU) timer or a Routing Area Update (RAU) timer for the UE.

11. The media of claim 8, wherein communicating the data to the UE includes paging the UE by the MME or the SGSN to receive the data from the application service.

12. The media of claim 8, wherein communicating the data to the UE includes communicating the data to the UE after the UE enters a connected mode.

13. A system comprising:

at least one memory element for storing data; and

at least one processor for executing instructions associated with the data, wherein the executing causes the system to perform operations, comprising;

registering, by an application service, to receive an indication from a Mobility Management Entity (MME) or a serving General Packet Radio Service (GPRS) support node (SGSN), wherein the indication is associated with an availability of a user equipment (UE) to receive data from the application service and wherein the registering is performed via a service capability exposure function (SCEF);

determining that a periodic timer for the UE is about to expire;

communicating to the application service, prior to expiration of the periodic timer for the UE, the indication associated with the availability of the UE to receive data from the application service; and

communicating the data from the application service to the UE upon receiving the indication.

14. The system of claim 13, wherein the registering includes subscribing by the application service to an event trigger for the MME or the SGSN.

15. The system of claim 14, wherein the executing causes the system to perform further operations, comprising:

configuring a mobile reachability timer for the MME or the SGSN, where the mobile reachability timer is associated with the event trigger and the periodic timer for the UE.

16. The system of claim 14, wherein the periodic timer is associated with a Tracking Area Update (TAU) timer or a Routing Area Update (RAU) timer for the UE.

17. The system of claim 14, wherein communicating the data to the UE includes at least one of:

paging the UE by the MME or the SGSN to receive the data from the application service; and

communicating the data to the UE after the UE enters a connected mode.
