Abstract

Aspects of the subject disclosure may include, for example, a network device that receives a failure message from a mobility management entity where the failure message indicates that a first connection request from an application server to an end user device failed based on the end user device being in an inactive mode, where the network device provides to the application server a target time for transmitting a second connection request to the end user device, and where the providing of the target time to the application server causes the application server to cease transmitting connection requests to the end user device until the target time. Other embodiments are disclosed.

Claims

1. A method comprising:

receiving, by a network device including a processor, a notification message from a mobility management entity, wherein the notification message indicates that a first connection request from an application server to an end user device failed based on the end user device being in an inactive mode, wherein the notification message includes first identification information for the end user device, second identification information for the application server, and timing information associated with an active time period for the end user device when the end user device will not be in the inactive mode; and

providing, by the network device to the application server, a target time for transmitting a subsequent connection request to the end user device, wherein the target time is within the active time period, and wherein the providing of the target time to the application server causes the application server to cease re-transmitting connection requests to the end user device until the target time,

wherein the first connection request is for communications of the end user device via a serving gateway, wherein the network device, the application server and the serving gateway are remote from each other.

2. The method of claim 1, comprising:

obtaining, by the network device, network status data corresponding to the active time period; and

selecting, by the network device, the target time within the active time period according to the network status data.

3. The method of claim 2, comprising:

prioritizing, by the network device, the first connection request among a group of connection requests to generate a priority for the first connection request,

wherein the selecting of the target time within the active time period is according to the priority for the first connection request.

4. The method of claim 2, wherein the network status data includes predicted network traffic corresponding to the active time period, and wherein the predicted network traffic is determined according to historical network traffic, scheduled network maintenance, or a combination thereof.

5. The method of claim 2, wherein the network status data includes predicted resource availability corresponding to the active time period, and wherein the predicted resource availability is determined according to historical resource availability, scheduled network maintenance, or a combination thereof.

6. The method of claim 1, wherein the first identification information for the end user device includes a first IP address, and wherein the second identification information for the application server includes a second IP address.

7. The method of claim 1, comprising:

identifying, by the network device, an application associated with the first connection request;

prioritizing, by the network device, the first connection request among a group of connection requests according to the identifying of the application to generate a priority for the first connection request; and

selecting, by the network device, the target time within the active time period according to the priority for the first connection request.

8. The method of claim 1, wherein the inactive mode comprises a power savings mode or a discontinuous reception and transmission mode.

9. An apparatus, comprising:

a processor; and

a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising;

receiving a failure message from a mobility management entity, wherein the failure message indicates that a first connection request from a server to a communication device has failed based on the communication device being in an inactive mode, wherein the failure message includes connection request information comprising first identification information for the communication device and second identification information for the server;

responsive to the failure message, registering with a home subscriber server based on the connection request information;

responsive to a determination of activity of the communication device, receiving an activity status message from the home subscriber server; and

responsive to the activity status message, providing a status update to the server that causes the server to send a second connection request to the communication device.

10. The apparatus of claim 9, wherein the operations further comprise providing a second failure message to the communication device that indicates that the first connection request from the server to the communication device failed based on the communication device being in the inactive mode.

11. The apparatus of claim 10, wherein the providing of the status update to the server is responsive to the providing of the second failure message to the communication device.

12. The apparatus of claim 9, wherein the determination of the activity of the communication device comprises detecting a network attachment by the communication device.

13. The apparatus of claim 9, wherein the status update includes a target time for transmitting the second connection request to the communication device.

14. The apparatus of claim 13, wherein the target time is determined according to network status data.

15. The apparatus of claim 13, wherein the target time is determined according to prioritizing the first connection request among a group of connection requests.

16. The apparatus of claim 9, wherein the communication device comprises an end user device, wherein the server comprises an application server, and wherein the second connection request is for communications of the end user device via a serving gateway that is remote from the application server.

17. A non-transitory machine-readable storage medium, comprising executable instructions that, when executed by a processor of an application server, facilitate performance of operations, comprising:

transmitting a first connection request to an end user device, wherein a result of the first connection request is a failure based on the end user device being in an inactive mode, wherein the failure of the first connection request causes a network device to receive a failure message from a mobility management entity, and wherein the failure message indicates the failure and includes first identification information for the end user device and second identification information for the application server;

receiving, from the network device, a target time for transmitting a second connection request to the end user device;

responsive to the receiving of the target time, ceasing transmitting connection requests from the application server to the end user device until the target time; and

transmitting a second connection request to the end user device according to the target time, wherein the target time is determined according to prioritizing the first connection request among a group of connection requests.

18. The non-transitory machine-readable storage medium of claim 17, wherein the failure message includes timing information associated with an active time period for the end user device when the end user device will not be in the inactive mode, and wherein the target time is within the active time period.

19. The non-transitory machine-readable storage medium of claim 17, wherein the target time is determined according to network status data.

20. The non-transitory machine-readable storage medium of claim 17, wherein the second connection request is for communications of the end user device via a serving gateway that is remote from the application server.
