Access terminal assisted node identifier confusion resolution using a time gap

摘要

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 a network may provide a time gap (e.g., an asynchronous time gap) during which an access terminal may temporarily cease monitoring transmissions from a source node so that the access terminal may acquire a unique identifier from a target node. In some aspects an access terminal may commence handover operations at a target node after determining whether the access terminal is allowed to access the target node. In some aspects a source node may prepare several target nodes for potential handover in the event confusion is detected or likely. Here, the source node may send information relating to the preparation of the potential target nodes to the access terminal whereby the access terminal uses the handover preparation information to initiate a handover at that target node.

1. A method of communication, comprising:
receiving at a first access point an indication based on a determination made by an access terminal that the access terminal is in the vicinity of a second access point in a closed subscriber group (CSG) list of the access terminal at which the access terminal may receive service; receiving a first identifier of the second access point; determining by the first access point whether to initiate handover operations based on the indication from the access terminal; determining by the first access point whether the first identifier may be used to identify at least one node other than the second access point; sending by the first access point, as a result of the determination that the first identifier is used to identify at least one node other than the second access point, a request for the access terminal to acquire a second identifier of the second access point; and receiving, at the first access point the second identifier of the second access point from the access terminal in response to the request.
