Abstract

Confusion resulting from assigning the same node identifier to multiple nodes is resolved through the use of confusion detection techniques and the use of unique identifiers for the nodes. In some aspects an access point and/or an access terminal may perform operations relating to detecting confusion and/or providing a unique identifier to resolve confusion.

First claim

What is claimed is:

1. A method of communication for an access terminal,
comprising:
determining, by the access terminal, a first identifier for establishing communication with an access point; and
determining, by the access terminal, based on the first identifier, a second identifier for establishing communication with the access point, wherein the access terminal autonomously determines when to acquire the second identifier without instructions by an external node,
wherein the determination of the second identifier based on the first identifier comprises determining whether a value of the first identifier is one of a set of designated values associated with access points of a closed subscriber group.

2. The method of claim 1 further comprising receiving a message indicative of whether a node other than the access point is also identified by the first identifier.

3. The method of claim 1 , further comprising using the second identifier for a subsequent attempt to establish communication with the access point.

4. The method of claim 1 , wherein:
the first identifier comprises a physical cell identifier associated with the access point, a pseudorandom number offset associated with the access point, or an acquisition pilot associated with the access point; and
the second identifier comprises a global cell identifier associated with the access point, an Internet Protocol address associated with the access point, or an identifier that uniquely identifies the access point within a network.

5. The method of claim 1 , wherein the at least one designated type relates to at least one of the group consisting of: transmit power, coverage area, and relay capabilities.

6. An access terminal apparatus for communication, comprising:
a communication controller configured to determine, at the access terminal apparatus, a first identifier for establishing communication with an access point; and
an identifier controller configured to determine, at the access terminal apparatus, based on the first identifier, a second identifier for establishing communication with the access point, wherein the access terminal apparatus autonomously determines when to acquire the second identifier without instructions by an external node, wherein the determination of the second identifier based on the first identifier comprises determining whether a value of the first identifier is one of a set of designated values associated with access points of a closed subscriber group,
wherein the communication controller and identifier controller are associated with at least one processor, the at least one processor coupled to a memory.

7. The access terminal apparatus of claim 6 , wherein the identifier controller receives a message indicative of whether a node other than the access point is also identified by the first identifier.

8. The access terminal apparatus of claim 6 , wherein the communication controller is further configured to use the second identifier for a subsequent attempt to establish communication with the access point.

9. The access terminal apparatus of claim 6 , wherein:
the first identifier comprises a physical cell identifier associated with the access point, a pseudorandom number offset associated with the access point, or an acquisition pilot associated with the access point; and
the second identifier comprises a global cell identifier associated with the access point, an Internet Protocol address associated with the access point, or an identifier that uniquely identifies the access point within a network.

10. The access terminal apparatus of claim 6 , wherein the at least one designated type relates to at least one of the group consisting of: transmit power, coverage area, and relay capabilities.

11. A non-transitory computer-readable medium comprising codes for causing an access terminal to:
determine, at the access terminal, a first identifier for establishing communication with an access point; and
determine, at the access terminal, based on the first identifier, a second identifier for establishing communication with the access point, wherein the access terminal autonomously determines when to acquire the second identifier without instructions by an external node, wherein the determination of the second identifier based on the first identifier comprises determining whether a value of the first identifier is one of a set of designated values associated with access points of a closed subscriber group.

12. The computer-readable medium of claim 11 , further comprising codes for causing the access terminal to receive a message indicative of whether a node other than the access point is also identified by the first identifier.

13. The computer-readable medium of claim 11 , wherein the computer-readable medium further comprises codes for causing the computer to use the second identifier for a subsequent attempt to establish communication with the access point.

14. A method for an access terminal in communication with a first access point to facilitate establishing communication with a second access point, comprising:
receiving, at the access terminal, a list of node identifiers from the first access point;
determining, by the access terminal, a first identifier associated with the second access point;
comparing, by the access terminal, the first identifier to the received list of node identifiers, the list of node identifiers comprising a set of designated values associated with access points of a closed subscriber group;
determining, by the access terminal, a second identifier associated with the second access point in response to the comparison, wherein determining the second identifier comprises determining whether a value of the first identifier is one of the set of designated values,
wherein the access terminal autonomously determines when to acquire the second identifier without instructions by an external node; and
transmitting, from the access terminal, a message to the first access point including an indication of the second identifier to facilitate establishing communication with the second access point.

15. The method of claim 14 , wherein the comparing comprises:
determining whether the first identifier is one of a defined set of node identifiers of a first type designated by the received list as requiring an additional identifier; and
determining to initiate determination of the second identifier when the first identifier corresponds to the first type.

16. The method of claim 14 , wherein determining the second identifier is performed by the access terminal autonomously without being instructed to do so by the first access point.
