Abstract: In accordance with embodiments of the invention, in a Wireless Local Area Network (WLAN) in accordance with the HIPERLAN Type 2 standard where an Access Point (AP) and Mobile Terminals (MTs) use a duplex airlink having a MAC frame structure to communicate with each other, the AP places wakeup PDUs at different locations in a MAC frame, for example at different locations within the Frame Control Channel (FCCH) or the Slow Broadcast Channel (SBCH), to allow the MTs to conserve energy by maximizing sleep time. In accordance with other embodiments of the invention, the wakeup PDUs are ordered or sequenced by MAC-ID so that an MT can conclusively determine whether remaining wakeup PDUs in a sequence can contain its MAC-ID, and go to sleep early if they cannot. In accordance with another embodiment of the invention, a wakeup PDU type can indicate to a corresponding MT whether the MT can expect downlink data later in the same MAC frame. In accordance with another embodiment of the invention, whether the MT should send a predetermined acknowledge signal to the AP in a) an allocated uplink channel in the same MAC frame, where the allocated uplink channel is identified in the wakeup PDU, or b) in the Random Access Channel (RACH) of the MAC frame. In addition, the wakeup PDU type can indicate to the MT that the MAC frame that it should awaken and remain awake to receive downlink data in the future.

Abstract: A method and apparatus for caching mobile station (110) location information comprising a gateway packet switch node (150) for receiving and transmitting data packets between a plurality of visiting packet switch nodes (130) and at least one communication network (175) and a cache memory (165) located within the gateway packet switch (150) for caching location information received with a data packet from a transmitting mobile station (110). A communication packet, containing information pertaining to the location of a transmitting mobile station (110) is received (230) by the gateway packet switch node (150). The location information is extracted (250) from the received communication packet and cached (260). When an incoming data packet is received (300) by the gateway packet switch node (150), a determination is made (310) as to whether the location information for the destination mobile station (110) is stored within the cache (165). If the location information is stored within the cache (165) the location information is retrieved (340) from the cache (165) and the data packet is routed (350) to the mobile station (110). Otherwise, the location information is retrieved (320) from a home location register (197) and the data packet is routed (330) to the mobile station (110).

Abstract: A Dual mode mobile terminal (MT2) comprising a WLAN interface (WLAN_NIC) and a cellular radio interface (GSM_NIC) has been described wherein when receiving a Page Request (6) message over the cellular radio interface (GSM_NIC), indicating an incoming voice call over the cellular radio interface, or upon receiving an indication from the user of the dual mode terminal to perform an outgoing voice call, performing a determination (7) as to whether a WLAN coverage is possible from an AP providing WLAN telephony calls, and if so responding, by issuing a WLAN call message (8) to a WLAN AP over the WLAN interface to an interworking node (IWFN). There is moreover provided an Interworking node (IWFN) comprising a cellular control unit (CTRL_SIP), a cellular unit (GSM_U), a voice over IP unit (VO_IP) and a router (R), which upon receiving a WLAN call (9) from a dual mode terminal via a WLAN AP, is establishing a connection against a serving mobile switching centre (S_MSC/VLR) (10,10a, 10b), is performing a call initiation procedure (12-15), a assign traffic channel procedure (16-20) and a call confirmation and call accepted procedure (22-27) between the dual mode terminal (MT2) and the serving switching mode centre (S_MSC/VLR), is initiating duplex GSM/IP translation (29) and is routing the cellular call between the AP and the serving mobile switching centre (S_MSC).

Abstract: The present invention provides a method and system for reducing the delay of the transmission of packet data including storing, by a base station, data associated with a mobile station from a first packet data transaction. A packet for starting a second packet data transaction is received from a mobile station and the base station determines whether or not the packet has been correctly received. The base station correlates at least one field in the packet with the stored data. If the base station is able to identify the mobile station based on the correlation with the stored data, then the base station reserves a resource for transmission of a subsequent packet from the mobile station regardless of whether or not the packet has been correctly received.

Abstract: The present invention is related to a method and apparatus for resource allocation in a communication system as well as a radio network control node ad a radio access network including such an apparatus. A request for allocation of a channel resource is received ( 301 ). In response, a specific channel resource is allocated ( 302 ) according to a predetermined rule which includes considering an estimate of when said specific channel resource will be released and estimates of when other previously allocated channel resources will be released.

Abstract: Método para reducir el retardo de la transmisión por radio de datos por paquetes, que comprende: recibir datos (220) para la transmisión entre una estación móvil y una estación base; asignar (222; 432) dicha estación móvil a una canal de paquetes; reservar una pluralidad de primeras oportunidades de transmisión para dicha estación móvil en un modo (302) activo; intercambiar datos (436) entre dicha estación móvil y dicha estación base durante al menos una de dicha pluralidad de primeras oportunidades de transmisión en dicho modo (302) activo; iniciar un primer temporizador después de dicho intercambio de datos con dicha estación móvil; reservar una pluralidad de segundas oportunidades de transmisión para dicha estación móvil en un modo (306) de radiolocalización rápida variable cuando dicho primer temporizador supera un primer valor umbral; y supervisar (440) dicha pluralidad de segundas oportunidades de transmisión para la detección de datos adicionales transmitidos; en el que dicho modo de radiolocalización rápida variable presenta un retardo mayor entre oportunidades de transmisión sucesivas que dicho modo activo, proporcionando de ese modo un número reducido de oportunidades de transmisión para supervisar datos transmitidos adicionales; y en el que se asigna a dicha estación móvil un mensaje que indica un tipo asociado con dicho modo de radiolocalización rápida variable; e iniciar un segundo temporizador después de dicha entrada en dicho modo de radiolocalización rápida variable; y salir de dicho modo de radiolocalización rápida variable cuando dicho segundo temporizador supera un segundo valor umbral.
