  • Patent number: 9661557
    Abstract: Systems and methodologies are described that facilitate providing neighbor lists to devices comprising pilot frequencies of access points in a specific geographic region. Using the neighbor list, the devices can discover the access points based on scanning the frequencies for the pilot and can determine additional communication parameters from the discovery or based on a subsequent request resulting from discovery. In this regard, access point information need not be provisioned to the devices for locating the access points, selecting/reselecting the access points, providing the access points in a list to an interface, locating the device using triangulation based on GPS position of the access points, and/or the like.

  • Patent number: 9648523
    Abstract: In a handover operation an access terminal is handed over from a source access point to a target access point. To facilitate efficient identification of a target access point, a handover operation may be initiated by the target access point. A candidate frequency search also may be invoked to confirm that an access terminal identified by a target access point for a handover is in the vicinity of the target access point. A source access point may verify whether an access terminal is in a vicinity of a target access point to determine whether to perform a handover operation. A source access point may handle potential ambiguity between several target access points by sending handover commands to each of these target access points. An access terminal also may assist in the determination of whether to perform a handover operation.

  • Patent number: 9510272
    Abstract: Systems and methodologies are described that facilitate distributing and/or utilizing a Closed Subscriber Group (CSG) Identifier (ID) that identifies a CSG corresponding to a base station and a CSG indication that distinguishes between the base station permitting access to members of the CSG and permitting access to members and non-members of the CSG. For instance, the CSG ID can uniquely identify the CSG corresponding to the base station. A mobile device can receive the CSG ID and the CSG indication from the base station. Further, the received CSG ID can be compared to CSG IDs included in an allowed CSG list to recognize whether the mobile device is a member or a non-member of the CSG. Moreover, a preference for selecting the base station as compared to a disparate base station can be generated as a function of the received CSG ID and CSG indication.
