Abstract

Systems and methodologies are described that facilitate utilizing restriction codes in rejecting connection requests with restricted association access points to indicate a reason for the rejection. Mobile devices can maintain a list of accessible access points and/or groups of access points, which can be consulted during cell reselection to ensure unsuitable restricted association access points are not utilized in cell reselection. Based on receiving a rejection code from a restricted association access point, a mobile device can remove the access point, or a related group, from its maintained list so that subsequent reselection attempts avoid the access point and/or access points in the related group.

Claims

1. A method for connection establishment in a wireless communication network, comprising:

determining whether a group identifier related to a restricted association access point is present in a maintained list of accessible access point group identifiers;

requesting connection establishment with the restricted association access point based at least in part on the determination; and

receiving a rejection in response to the requesting connection establishment, the rejection comprises a restriction code that indicates the group identifier is unsuitable for establishing the requested connection.

2. The method of claim 1, further comprising deleting the group identifier from the maintained list of accessible access point group identifiers based at least in part on the rejection.

3. The method of claim 2, wherein deleting the group identifier from the list is further based at least in part on a restriction code.

4. The method of claim 1, wherein requesting connection establishment is performed over the air and the rejection is received over the air from the restricted association access point.

5. The method of claim 1, wherein requesting connection establishment is performed over a backhaul connection with the restricted association access point and the rejection is received over the backhaul connection.

6. The method of claim 1, further comprising participating in cell reselection from a disparate access point where requesting connection establishment is performed during the cell reselection.

7. The method of claim 1, wherein the group identifier related to the restricted association access point is text based.

8. The method of claim 1, wherein the restricted association access point is restricted from providing signaling, data access, registration, and/or service based at least in part on the restriction code.

9. The method of claim 1, wherein the requesting connection establishment comprises including authentication information in the request.

10. A wireless communications apparatus, comprising:

at least one processor configured to;

verify presence of a group identifier related to a restricted association access point within a maintained list of accessible access point group identifiers;

request connection establishment with the restricted association access point based at least in part on the presence of the group identifier in the maintained list; and

receive a restriction code in response to the requesting connection establishment indicating the group identifier is unsuitable for connection establishment; and

a memory coupled to the at least one processor.

11. A wireless communications apparatus that facilitates establishing connection with one or more access points in wireless communications, comprising:

means for determining that a group identifier related to a restricted association access point is present in a maintained list of accessible access point group identifiers;

means for requesting connection establishment with the restricted association access point based at least in part on the determination; and

means for receiving a restriction code in response to the requesting connection establishment indicating establishing connection with the restricted association access point is restricted.

12. A computer program product, comprising:

a computer-readable medium comprising;

code for causing at least one computer to determine whether a group identifier related to a restricted association access point is present in a maintained list of accessible access point group identifiers;

code for causing the at least one computer to request connection establishment with the restricted association access point based at least in part on the determination; and

code for causing the at least one computer to receive a rejection in response to the requesting connection establishment, the rejection comprises a restriction code that indicates the group identifier is unsuitable for establishing connection.

13. An apparatus, comprising:

an access list controller that maintains a list of accessible access point group identifiers and determines a group identifier related to a restricted association access point is present in the list;

a connection requestor that requests connection establishment with the restricted association access point based at least in part on the determination by the access list controller; and

a restriction code receiver that receives a restriction code in response to the requesting connection establishment indicating the group identifier is unsuitable for establishing connection.

14. The apparatus of claim 13, wherein the access list controller deletes the group identifier from the maintained list of accessible access point group identifiers based at least in part on the restriction code.

15. The apparatus of claim 13, wherein the connection requester requests connection establishment over the air and the restriction code receiver receives the restriction code over the air from the restricted association access point.

16. The apparatus of claim 13, wherein the connection requester requests connection establishment over a backhaul connection with the restricted association access point and the restriction code receiver receivers the restriction code over the backhaul connection.

17. The apparatus of claim 13, further comprising a cell reselector that participates in cell reselection from a disparate access point where the connection requestor requests the connection establishment during the cell reselection.

18. The apparatus of claim 13, wherein the group identifier related to the restricted association access point is text based.

19. The apparatus of claim 13, wherein the restriction code receiver determines the restricted association access point is restricted from providing signaling, data access, registration, and/or service to the apparatus based at least in part on the restriction code.

20. The apparatus of claim 13, wherein the connection requester includes authentication information in the request for connection establishment.
