Method of providing access information to an access terminal

1. A method, comprising:

denying, at an access network, an access request for a new wireless connection over an air interface from at least one idle access terminal to the access network

when insufficient resources are available to support the new wireless connection;

selecting, in response to denying the access request, a future time for said at least one idle access terminal to transmit a re-access request using information indicative of future accessibility of the access network to said at least one idle access terminal over the wireless connection;

transmitting, from the access network, information denying the access request and indicating the selected future time for said at least one idle access terminal to transmit the re-access request for the wireless connection; and

queuing the access request at the access network until the selected future time.

2. The method of claim 1 , further comprising providing the information to said at least one idle access terminal in a Connection Deny message.

3. The method of claim 2 , wherein selecting the future time using the information indicative of future accessibility of said at least one access network comprises:

determining at least one re-access time slot during which said at least one idle access terminal is scheduled to transmit the re-access request over the air interface;

providing information indicative of said at least one re-access time slot to said at least one idle access terminal; and

queuing the access request until said at least one re-access time slot has passed.

4. The method of claim 1 , further comprising granting access to said at least one idle access terminal prior to said at least one re-access time slot when sufficient resources become available to support the new wireless connection while the access request is queued by the access network.

5. The method of claim 3 , wherein selecting said at least one re-access time slot comprises selecting said at least one re-access time slot based on at least one priority associated with said at least one idle access terminal.

6. The method of claim 3 , wherein queuing the access terminal comprises queuing said at least one idle access terminal in a queue containing a plurality of other idle access terminals in the order in which access requests by the idle access terminals were denied, and wherein selecting said at least one re-access time slot comprises selecting said at least one re-access time slot based on a position of said at least one idle access terminal in the queue.

7. The method of claim 3 , wherein selecting said at least one re-access time slot comprises selecting said at least one re-access time slot based on at least one time offset associated with at least one sector including said at least one idle access terminal.

8. The method of claim 1 , comprising determining information indicative of the future accessibility of the access network over the air interface, wherein determining the information indicative of future accessibility comprises determining information indicating that the system is busy.

9. The method of claim 8 , wherein determining the information indicative of future accessibility of the access network comprises determining the information indicative of future accessibility based on at least one service grade associated with said at least one idle access terminal.

10. The method of claim 9 , wherein determining the information indicative of future accessibility based on said at least one service grade comprises determining the information indicative of future accessibility based on at least one of an emergency status of the idle access terminal, a test status of the idle access terminal, and a latency status of the idle access terminal.

11. A method, comprising:

receiving, at an idle access terminal over an air interface, information denying an access request for a new wireless connection to an access network; and

receiving, at the idle access terminal, information indicating a future time for the idle access terminal to transmit a re-access request for the new wireless connection, the future time being selected using information indicating future accessibility of the access network, and wherein the access request is queued by the access network until the future time.

12. The method of claim 11 , wherein receiving the information indicating the future time comprises receiving information indicative of at least one re-access time slot of the air interface.

13. The method of claim 12 , further comprising receiving at least one message granting access to said at least one access request prior to said at least one re-access time when sufficient resources become available to support the new wireless connection while the access request remains queued by the access network.

14. The method of claim 12 , wherein receiving the information indicative of said at least one re-access time slot comprises receiving information indicative of at least one re-access time slot determined based on at least one priority assigned to the idle access terminal.

15. The method of claim 12 , wherein receiving the information indicative of said at least one re-access time slot comprises receiving information indicative of at least one re-access time slot determined based on a queue at the access network including the idle access terminal.

16. The method of claim 12 , wherein receiving the information indicative of said at least one re-access time slot comprises receiving information indicative of at least one re-access time slot determined based on a time offset associated with at least one neighbor sector.

17. The method of claim 11 , wherein receiving the information indicative of the re-access time slot comprises receiving information indicating that the system is overloaded.

18. The method of claim 11 , wherein receiving the information indicative of the re-access time slot comprises receiving the information indicative of a re-access time slot selected based on at least one service grade associated with the idle access terminal.

19. The method of claim 18 , wherein receiving the information indicative of a re-access time slot selected based on said at least one service grade comprises receiving the information indicative of a re-access time slot selected based on at least one of an emergency status of the idle access terminal, a test status of the idle access terminal, and a latency status of the idle access terminal.

20. The method of claim 11 , comprising transmitting the re-access request for the new wireless connection at the future time.
