    Abstract: SYSTEMS AND METHODOLOGIES ARE DESCRIBED THAT FACILITATE IMPROVED MULTI-MODE SYSTEM SELECTION IN A WIRELESS COMMUNICATION SYSTEM (100). AS DESCRIBED HEREIN, VARIOUS TECHNIQUES CAN BE UTILIZED TO SYNTHESIZE SYSTEM DATABASES CORRESPONDING TO DISPARATE GROUPS OF RADIO ACCESS TECHNOLOGIES (RATS), SUCH AS A PUBLIC LAND MOBILE NETWORK (PLMN) LIST (310, 510, 610, 710) AND/OR A PREFERRED ROAMING LIST (PRL) (320, 520, 620, 720), WITH ONE OR MORE OVERLAY DATABASES AND ASSOCIATED LOCATION INFORMATION TO GENERATE A MULTI-MODE LIST OF PREFERRED SYSTEMS. AS DESCRIBED HEREIN, A PREFERRED SYSTEM LISTING CAN BE CONSTRUCTED TO LEVERAGE FINE GRANULARITY OF INFORMATION IN ONE OR MORE DATABASES WHILE STILL SUPPORTING DATABASES WITH COARSER INFORMATION. TECHNIQUES ARE ADDITIONALLY DESCRIBED HEREIN FOR AUGMENTING AND/OR GROUPING ONE OR MORE OVERLAY DATABASES TO FACILITATE A HIGHER AVAILABLE GRANULARITY OF INFORMATION FOR VARIOUS RATS THAN THAT PROVIDED IN SYSTEM DATABASES CORRESPONDING TO THE RATS. TECHNIQUES ARE ADDITIONALLY PROVIDED FOR AUTOMATED GENERATION OF PREFERRED SYSTEM LISTING BASED ON CHANGES TO OBSERVED LOCATION.

    Abstract: Systems and methodologies are described that facilitate device-side access point list management. Blacklists of access points unsuitable for providing network access to a related mobile device can be maintained as well as whitelists of suitable access points. The lists can be managed using an interface provided at the mobile device. In addition, lists can be modified according to provisioned network updates. Also, the lists can be of maximum size such that older entries can be purged upon insertion of newer entries based on a number of factors; timed entry deletion is provided as well. Access points in the lists can be stored and presented according to various identifiers related to the access points.

    Abstract: Systems and methodologies are described that facilitate improved multi-mode system selection in a wireless communication system. As described herein, various techniques can be utilized to synthesize system databases corresponding to disparate groups of radio access technologies (RATs), such as a Public Land Mobile Network (PLMN) list and/or a Preferred Roaming List (PRL), with one or more overlay databases and associated location information to generate a multi-mode list of preferred systems. As described herein, a preferred system listing can be constructed to leverage fine granularity of information in one or more databases while still supporting databases with coarser information. Techniques are additionally described herein for augmenting and/or grouping one or more overlay databases to facilitate a higher available granularity of information for various RATs than that provided in system databases corresponding to the RATs. Techniques are additionally provided for automated generation of preferred system listing based on changes to observed location.

    Abstract: Systems and methodologies are described that facilitate identifying and/or selecting femto cells in a wireless communication environment. A mobile device can scan an Auxiliary Pilot Channel to detect auxiliary pilot channel information (e.g., a particular Walsh Code, ) sent from a base station. Moreover, the identified auxiliary pilot channel information can be evaluated to detect a characteristic of the base station. For instance, the identified auxiliary pilot channel information can be compared with stored auxiliary pilot channel information (e.g., Walsh Code(s) included in a whitelist, blacklist, ). Moreover, a Synchronization Channel can be read based upon the detected characteristic. Further, a Common Pilot Channel, for example, can be analyzed to search for pseudo-noise (PN) offset(s) reserved for femto cell base stations, and the scan of the Auxiliary Pilot Channel can be initiated in response to detecting at least one reserved PN offset.

    Abstract: Cellular network may introduce a large number of limited access/limited range ("small") base stations deployed by end-users such as home base nodes (HNBs) or Femtocells that provide access to access terminals (ATs) or user equipment (UE) to a core network. A selective discovery approach enables UE to discover and to use a small base station without wasting power to discover an alien base station or to search when not within range of any open small base station. Discovery can entail location-dependent determination (e.g., macro base station triangulation, global positioning system, local broadcast channel, etc.) of being within range of an open femtocell whose identity was manually learned, accessed via a distributed neighbor list, etc. The UE can advantageously tolerate small changes in location without having to relearn the identity of the femtocell. The type of access afforded is advantageously communicated to end user via a display indicator.
