Abstract: A method for performing an inter-technology handover in a wireless communication system in which a mobile subscriber station (MSS) changes base stations (BS) begins by locating one or more target BSs that the MSS can handover to. The technology used by each target BS is identified, and the technology supported by the MSS is determined. A handover of the MSS is performed to a target BS with which the MSS can communicate.

Abstract: Metodo y aparato para servicios de entrega de voz/datos dentro de una piconet que opera sobre un rango limitado o sobre una WLAN (1803) comunicandose con dispositivos 3GPP a traves de reformatear los datos en formato IP antes de entregarlos a la WLAN (1803). El servicio es Servicio de Mensaje Corto (SMS, del ingles 'Short Message Service') (102). A la recepcion del mensaje SMS, se recupera la informacion relevante de la ruta. Se identifica una direccion PDGW (1805) para el mensaje SMS y se envia a la direccion PDGW que identifica al equipo de usuario (EU) WLAN (1801) para recibir el SMS y reformatea el mensaje SMS en formato IP para entregarlo al EU. Se proporciona una arquitectura de protocolo para la entrega de SMS sobre WLAN's, en particular para los SMS basados en UMTS/CDMA sobre WLAN (1803) a traves de dos mecanismo alternativos: tuneleo SMS y proxy SMS, para los protocolos para la entrega de SMS a traves de la WLAN (1803).

Abstract: The base station includes a communication circuit for enabling simultaneous communications between a number of ports and a number of the subscriber stations over a given communication channel having multiple sequentially repetitive time slots. An exchange is included to connect the communication circuit to the external communication network ports. A remote-connection process is coupled to the communication circuit by the exchange and by a base-station control channel occupying a selected one of the time slots for monitoring the status of the other time slots. The connection processor causes the communication circuit and the exchange to complete a connection between a given communication network port and a given subscriber station over a time slot assigned in response to the monitored status in accordance with a predetermined assignment routine.

Abstract: Apparatus and method for providing an automatic handoff process of a user equipment (UE) from either a wireless local area network (WLAN) to a universal mobile telecommunications system (UMTS) or from a UMTS to a WLAN. Handoffs may be initiated by the UE, based upon user preference, signal quality, comparison of location coordinates of the UE and the system to be switched to or signal quality. The available channels of one system may be broadcast to the UE by the other system or the UE may monitor channels of the system to be switched to and lock on to one. The handoff may also be initiated by the UMTS, the selection being power-based.

Abstract: The present invention provides a new communication mechanism between the UE and the GGSN pertaining to Resource Reservation Protocol (RSVP) signaling, and coordinates and assigns responsibility for RSVP messaging. This ensures proper RSVP messaging, prevents unnecessary consumption of radio resources and reduces chances of collisions within the network. Also, the invention prevents the possibility that neither the UE nor GGSN respond appropriately to the RSVP requirements by halting transmission of any RSVP path/refreshment messages to the IP network in order to refresh/maintain the reservation states due to lack of clear assignment of responsibility. This lack of clear understanding between the UE and the GGSN may result in the expiration of the IP network resource reservations made earlier for media streams.
