Abstract: A wireless access point (102) detects an indicia of a change in wireless connectivity of a mobile station (101) with respect to itself and another wireless access point (103). The wireless access point then automatically effects at least one of establishing a communication between itself and the second wireless access point regarding the change in wireless connectivity and/or establishing a temporary data tunnel as between itself and the second wireless access point. These network elements can also act to automatically establish a data flow path for the mobile station as between the second wireless access point and a network element (such as a mobility management agent (105)) that is external to the common subnet. In a preferred approach this comprises, at least in part, automatically sending a registration request to the network element other than in response to a specific request from the mobile station to send such a registration request.

Abstract: Mobile station information is exchanged between a plurality of distributed mobility agents (106, 108). The exchange is initiated by a mobility agent (106) associated with a last known network access point (110) that has communicated with the mobile station (114). The mobile station (114) is paged from at least one network access point using an available air interface technology to interface with the mobile station (114) and using the mobile station information. No centralized controller is used in the paging.

Abstract: Systems and techniques for handover management in wireless communication networks. An apparatus, such as a base station, receives information relating to load conditions and computes handover threshold information based on the information relating to the load conditions. The information relating to the load conditions may comprise information received from other base stations, and the base station may in turn share its own information. Information may be shared through direct communication between base stations, or may be managed by a controller. Handover thresholds may be set for user devices based on the load metric information.

Abstract: A method and apparatus for managing delivery of information in a wireless network (100) includes bearer plane information handlers (110, 111), each of which maintains a database of paging controller associations (200). Each paging controller association is an association of an idle mobile device to a last known paging controller of that idle mobile device. The apparatus also includes paging controllers (115-118), each of which is associated with at least one paging area (130-133). For each paging area, the paging controller maintains a database of all base transmitters of the paging area that are associated with the paging controller (310) and maintains a database of other selected paging controllers that control base transmitters in the paging area (315). Using these resources, the method uses location notification messages and paging responses to deliver bearer plane information to a mobile device (125) that has been idle.

Abstract: Timing synchronization between base stations of uncoordinated communication networks includes obtaining timing synchronization information from one base station, and adjusting a clock of the other station in response to the synchronization information. The timing synchronization information can be identified from a strongest synchronization signal from nearby uncoordinated base stations. The timing synchronization can accommodate clock offsets and frequency offsets.

Abstract: A method (1700) and apparatus (1801) provide channel estimation with extended bandwidth filters. Antenna (1813) receives a signal such as a pilot signal and detects a bandwidth associated with the pilot signal in a detector (320). One of a plurality of filters (603, 605, 607, and 609) including extended bandwidth filters (311) and a default filter (305) can be selected by a selector (617). If the detector detects activity associated with a wider bandwidth, the filter associated with the wider bandwidth is selected over the presently selected filter. If no activity is detected, the default filter is selected.
