Abstract

Systems and methods for processing a data over signaling (DoS) message at an access terminal are disclosed. A message is received at an access terminal. The message is decoded to determine if it is a DoS message. Upon detecting the DoS message a sleep delay timer is set to prevent the access terminal from entering a sleep state for a predetermined time.

Claims

1. A method comprising:

detecting a data over signaling (DoS) message at an access terminal; and

delaying a sleep state at the access terminal for a predetermined time after detection of the DoS message, wherein delaying the sleep state further comprises;

activating a sleep delay timer; and

preventing the sleep state while the sleep delay timer is active,

wherein the DoS message is generated in response to a message from a server to an access network requesting communication with the access terminal.

2. The method of claim 1, further comprising:

deactivating the sleep delay timer, after an application receives the DoS message.

3. The method of claim 1, further comprising:

restarting the sleep delay timer, if a subsequent DoS message is received, to allow the predetermined time to elapse for the subsequent DoS message.

4. The method of claim 1, wherein detecting the DoS message further comprises:

receiving a packet at a physical layer; and

decoding the packet at a medium access (MAC) layer to detect if it contains the DoS message.

5. The method of claim 1, wherein the access terminal is at least one of a mobile terminal, a cellular phone, or wireless device.

6. The method of claim 1, wherein delaying the sleep state at the access terminal further comprises staying awake in preparation for responding to the DoS message.

7. The method of claim 2, wherein the application is a push-to-talk application resident on the access terminal.

8. The method of claim 2, further comprising:

receiving an indication that the application has completed processing the DoS message; and

deactivating the sleep delay timer after receiving the indication.

9. The method of claim 4, further comprising:

forwarding the DoS message to an application layer.

10. The method of claim 5, wherein the access network transmits the DoS message to the access terminal over an air interface.

11. The method of claim 10, wherein the server is a group communication server.

12. A system comprising:

means for detecting a data over signaling (DoS) message at an access terminal;

means for delaying a sleep state at the access terminal for a predetermined time after detection of the DoS message, wherein delaying the sleep state further comprises;

means for activating a sleep delay timer; and

means for preventing the sleep state while the sleep delay timer is active; and

a communication means, wherein the DoS message is generated in response to a message from the communication means to an access network requesting communication with the access terminal.

13. The system of claim 12, wherein delaying the sleep state further comprises:

means for deactivating the sleep delay timer, after an application receives the DoS message.

14. The system of claim 12,

wherein the communication means is a group communication means.

15. The system of claim 13, further comprising:

means for restarting the sleep delay timer, if a subsequent DoS message is received to allow the predetermined time to elapse for the subsequent DoS message.

16. A non-transitory computer readable media embodying a method for processing messages at an access terminal, the method comprising:

detecting a data over signaling (DoS) message at the access terminal; and

delaying a sleep state at the access terminal for a predetermined time after detection of the DoS message, comprising;

activating a sleep delay timer; and

preventing the sleep state while the sleep delay timer is active,

wherein the DoS message is generated in response to a message from a server to an access network requesting communication with the access terminal.

17. The computer readable media of claim 16, wherein the method further comprises:

deactivating the sleep delay timer, after an application receives the DoS message.

18. The computer readable media of claim 16, wherein the method further comprises:

restarting the sleep delay timer, if a subsequent DoS message is received to allow the predetermined time to elapse for the subsequent DoS message.
