Abstract: An access terminal adapts (e.g., self-optimizes) at least one handover parameter used by the access terminal for determining whether and/or how to handover from one access point to another access point. In addition, the access terminal uses different handover parameters for handover between different pairs of access points. For each of the access point pairs, the access terminal maintains a record of any handover issues that occur during handover of the access terminal between the access points. In the event a handover issue arises for a given pair of access points, the access terminal may adapt the handover parameter(s) associated with that access point pair in an attempt to mitigate the handover issue. In the event handover parameter adaptation occurs or occurs too frequently, the access terminal may store the adapted handover parameters for use during a subsequent handover operation and/or handover parameter adaptation operation.
