Abstract: A method and apparatus for triggering procedures to handover an ongoing communication session between a mobile station (MS) and a correspondent node (CoN) from via a first network of a first type to via a second network of a different type. Communication session continuity is maintained by transferring communication session context information when a handover is imminent from a network component in a first network path to a network component in a second network path, and by forwarding downlink and uplink signals via the network components in both the first and second network paths until the ongoing communication session can be established via the second network path. The context information includes the session communication parameters, such that the second network path can allocate resources and establish routing between the MS and the CoN.

Abstract: La presente invencion se refiere a un procedimiento de puesta en marcha de un punto de acceso (AP) que incluye una fase de descubrimiento y una fase de anuncio. Durante la fase de descubrimiento, el AP detecta Aps vecinos de su propio conjunto de servicio extendido (ESS), Aps vecinos de ESSs diferentes, y fuentes externas de interferencia. Durante la fase de anuncio, el AP transmite sus senales de baliza a potencia maxima para acelerar el reconocimiento por Aps vecinos que corren la fase de descubrimiento. Un procedimiento de seleccion de canal de inicializacion automatico de un AP escanea canales que el AP utilizara para comunicarse. Se registra informacion de cada canal escaneado y se determina un canal de mejor desempeno para uso por el AP.

Abstract: This invention relates to wireless local area networks (WLANs), and the interoperability of networks of different types or conforming to different standards, and to methods and apparatus to allow a multimode wireless transmit/receive unit (WTRU), which is able to operate in more than one type of network, to handover from one network type to another without adversely affecting service, utilizing a mechanism and information flows implemented in a new protocol stack.

Abstract: A method for communicating a list of handover candidates in a wireless local area network from a station to a serving access point (AP) begins by determining a list of handover candidate APs at the station. The candidate list is sorted at the station and is sent to the serving AP. The sending step can include sending the candidate list to the serving AP upon the expiration of a predetermined period of time or upon receipt at the station of an event trigger. The method can also include the step of requesting a candidate list from the station by the serving AP.

Abstract: A startup process of an access point (AP) includes a discovery phase and an announcement phase. During the discovery phase, the AP detects neighboring APs from its own extended service set (ESS), neighboring APs from different ESSs, and external sources of interference. During the announcement phase, the AP transmits its beacon signals at maximum power in order to accelerate recognition by neighboring APs running the discovery phase. An automatic initialization channel selection process of an AP scans channels the AP will use to communicate. Information of each scanned channel is recorded and a best performance channel is determined for use by the AP.

Abstract: The present invention is a method and system for monitoring and controlling congestion in a CDMA system having multi-user detection capabilities. The method detects congestion in the uplink by calculating noise rise based on user equipment measurements or radio access network measurements. Upon detection of congestion, congestion relieving measures are implemented as needed.
