1. A method for use in a wireless communications network, comprising:
- determining presence of a plurality of wireless local area networks in a particular cell segment;
determining which of the plurality of wireless local area networks a mobile station in the particular cell segment is authorized to use; and
sending a neighbor list to the mobile station in the particular cell segment to enable the mobile station to hand off to one or more of the wireless local area networks the mobile station is authorized to use, wherein the neighbor list contains one or more identifiers of the one or more wireless local area networks the mobile station is authorized to use, and identifiers of cell segments neighboring the particular cell segment.

Abstract
In a wireless communications network, the presence of a wireless local area network in a cell segment is determined. An identifier of the wireless local area network in the cell segment is sent to at least one mobile station in the cell segment to enable the at least one mobile station to hand off to the wireless local area network. Optionally, information identifying geographic boundaries of cell segments and the wireless local area network can be sent to the at least one mobile station.

10. An article comprising at least one non-transitory computer-readable storage medium containing instructions that when executed cause a system to:
-
determine presence of a wireless local area network in a cell segment; send an identifier of the wireless local area network to a mobile station to enable handoff of the mobile station from the cell segment to the wireless local area network; and store a mapping between a private identifier and a service set identifier (SSID) of the wireless local area network, wherein sending the identifier to the mobile station comprises sending the private identifier instead of the SSID. - View Dependent Claims (11, 12, 13, 14)

15. A system comprising:
-
an interface to a wireless link for communicating with a plurality of mobile stations; and a processor to; send a first neighbor list message to a first one of the mobile stations, the first neighbor list message containing identifiers associated with a first set of neighbors to which the first mobile station is able to hand off, wherein the first set of neighbors includes a wireless local area network in a particular cell segment, and the first set of neighbors further includes cell segments neighboring the particular cell segment; send a second neighbor list message to a second one of the mobile stations, the second neighbor list message identifying a second, different set of neighbors to which the second mobile station is able to hand off; and store a mapping between a private identifier and a service set identifier (SSID) associated with the wireless local area network, wherein the identifier associated with the wireless local area network in the neighbor list includes the private identifier. - View Dependent Claims (16, 17, 18)
