Abstract

Systems and methods for predictive QoS resource allocation in a wireless communication system are disclosed. An access network can detect a communication directed to an access terminal requiring QoS resources, send a page to an access terminal and allocate the QoS resources prior to receipt of the connection request from the access terminal.

First claim

What is claimed is:

1. A method for allocating quality of service (QoS) resources comprising:
detecting, by a radio access network, a communication request for a communication requiring QoS resources directed to an access terminal; and
allocating, by the radio access network, the QoS resources prior to receiving a request from the access terminal to allocate the QoS resources, based on the detecting.

2. The method of claim 1 , further comprising:
paging the access terminal in response to detecting the communication request;
receiving a connection request from the access terminal based on the paging; and
establishing a connection with the access terminal with the allocated QoS resources.

3. The method of claim 2 , wherein the QoS resources are allocated prior to the connection request.

4. The method of claim 2 , wherein the access terminal checks for the allocated QoS resources in the established connection.

5. The method of claim 4 , wherein the access terminal directly accepts the communication request without requesting additional QoS resources.

6. The method of claim 1 , wherein the communication request is for a push-to-talk call.

7. The method of claim 1 , wherein Differentiated Services Code Point (DSCP) values are used to detect the communication for the communication request requiring QoS services.

8. The method of claim 1 , further comprising:
detecting QoS resources currently allocated to the access terminal; and
allocating additional QoS resources needed for the communication request.

9. The method of claim 1 , wherein the QoS resources are allocated for In-Call Signaling and Media reservations.

10. The method of claim 1 , further comprising:
determining that insufficient QoS resources are available;
paging the access terminal;
receiving a connection request from the access terminal; and
establishing a connection with the access terminal without the allocated QoS resources.

11. An apparatus comprising:
a logic circuit configured to detect, by a radio access network, a communication request for a communication requiring quality of service (QoS) resources directed to an access terminal; and
a logic circuit configured to allocate, by the radio access network, the QoS resources prior to reception of a request from the access terminal to allocate the QoS resources, based on detection of the communication request.

12. The apparatus of claim 11 , further comprising:
a logic circuit configured to page the access terminal in response to detection of the communication request;
a logic circuit configured to receive a connection request from the access terminal based on the page; and
a logic circuit configured to establish a connection with the access terminal with the allocated QoS resources.

13. The apparatus of claim 12 , wherein the QoS resources are allocated prior to the connection request.

14. The apparatus of claim 12 , wherein the access terminal checks for the allocated QoS resources in the established connection.

15. The apparatus of claim 14 , wherein the access terminal directly accepts the communication request without requesting additional QoS resources.

16. The apparatus of claim 11 , wherein the communication request is for a push-to-talk call.

17. The apparatus of claim 11 , wherein Differentiated Services Code Point (DSCP) values are used to detect the communication request for the communication requiring QoS services.

18. The apparatus of claim 11 , further comprising:
a logic circuit configured to detect QoS resources currently allocated to the access terminal; and
a logic circuit configured to allocate additional QoS resources needed for the communication request.

19. The apparatus of claim 11 , wherein the QoS resources are allocated for In-Call Signaling and Media reservations.

20. The apparatus of claim 11 , further comprising:
a logic circuit configured to determine that insufficient QoS resources are available;
a logic circuit configured to page the access terminal;
a logic circuit configured to receive a connection request from the access terminal; and
a logic circuit configured to establish a connection with the access terminal without the allocated QoS resources.

21. The apparatus of claim 11 , wherein the apparatus is at least one of a radio access network, a group communication system, or a wireless communication network.

22. A wireless communication system configured to allocate quality of service (QoS) resources, the wireless communication system comprising:
means for detecting, by a radio access network, a communication request for a communication requiring QoS resources directed to an access terminal; and
means for allocating, by the radio access network, the QoS resources prior to reception of a request from the access terminal to allocate the QoS resources, based on detection of the communication request.

23. The wireless communication system of claim 22 , further comprising:
means for paging the access terminal in response to detection of the communication request;
means for receiving a connection request from the access terminal based on the page; and
means for establishing a connection with the access terminal with the allocated QoS resources.

24. The wireless communication system of claim 22 , wherein Differentiated Services Code Point (DSCP) values are used to detect the communication request for the communication requiring QoS services.

25. The wireless communication system of claim 22 , further comprising:
means for detecting QoS resources currently allocated to the access terminal; and
means for allocating additional QoS resources needed for the communication request.

26. The wireless communication system of claim 22 , further comprising:
means for determining that insufficient QoS resources are available;
means for paging the access terminal;
means for receiving a connection request from the access terminal; and
means for establishing a connection with the access terminal without the allocated QoS resources.

27. A non-transitory computer-readable medium including code stored thereon for allocating quality of service (QoS) resources comprising:
code for causing a radio access network to detect a communication request for the communication requiring QoS resources directed to an access terminal; and
code for causing the radio access network to allocate the QoS resources prior to reception of a request from the access terminal to allocate the QoS resources, based on detection of the communication request.

28. The non-transitory computer-readable medium of claim 27 , further comprising:
code for causing a computer to page the access terminal in response to detection of the communication request;
code for causing a computer to receive a connection request from the access terminal based on the page; and
code for causing a computer to establish a connection with the access terminal with the allocated QoS resources.

29. The non-transitory computer-readable medium of claim 27 , further comprising:
code for causing a computer to detect QoS resources currently allocated to the access terminal; and
code for causing a computer to allocate additional QoS resources needed for the communication request.

30. An access terminal comprising:
a logic circuit configured to receive a page from an access network;
a logic ci
