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. An apparatus, comprising:

a memory storing executable instructions; and

a processor in communication with the memory, wherein the processor is configured to execute the instructions to;

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

delay a sleep state at the access terminal for a predetermined time after detection of the DoS message, wherein in delaying the sleep state, the processor is further configured to;

activate a sleep delay timer; and

prevent 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 apparatus of claim 1, wherein the processor is further configured to execute the instructions to deactivate the sleep delay timer, after an application receives the DoS message.

3. The apparatus of claim 1, wherein the processor is further configured to execute the instructions to restart the sleep delay timer, if a subsequent DoS message is received to allow a predetermined time to elapse for the subsequent DoS message.

4. The apparatus of claim 1, wherein in detecting the DoS message the processor is further configured to execute the instructions to:

receive a packet at a physical layer; and

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

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

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

7. The apparatus of claim 4, wherein the processor is further configured to execute the instructions to forward the DoS message to an application layer.

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

9. The apparatus of claim 8, wherein the server is a group communication server.
