    Abstract: The present invention provides a method and system for quickly deallocating packet traffic channels. According to exemplary embodiments of the present invention, the capability of performing point-to-multipoint communications is provided on the PTCH by defining a multicast address that all mobiles read. Through the use of a multicast address, a plurality of mobile stations can simultaneously be notified of the termination of PTCH services. As a result, the network can reallocate PTCH resources in a minimum amount of time.

    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: In a wireline or wireless telecommunications system or data network, which employs a Selective Repeat Automatic Repeat Request (ARQ) to convey data packet reception status for a sequence of data packets grouped together into a number of blocks of data packets, partial bit mapping is employed to improve efficiency, particularly with respect to bandwidth. This may be accomplished , more specifically, by including in the ARQ message that is sent from the receiver to the sender, a number of partial bitmaps, along with a corresponding number of bitmap block numbers, where a first bitmap block number identifies a particular one of the blocks of data packets and the corresponding bitmap defines the reception status of the data packets in tha t block. Each of the remaining bitmap block numbers identify an additional blo ck of data packets relative to the first block of data packets. Accordingly, th e remaining bitmap block numbers require fewer bits to identify their corresponding data packet blocks.

    Abstract: Metodo para la asignación y manejo de prioridad del enlace ascendente llamado tambien UL, y del enlace descendente, llamado tambien DL, recursos en un sistema de telecomunicación que comprende al menos un controlador de red de radio (12, 12', 12''), llamado tambien RNC, y al menos un Nodo-B 11, 11', 11'', llamado tambien NB, para permitir la comunicación inalambrica con al menos un terminal de usuario (15), llamado tambien UE, estableciendo el RNC (12, 12', 12'') al menos un canal de transporte dedicado mejorado, llamado tambien E-DCH, que permite trafico de datos en el enlace ascendente con una determinada velocidad de datos maxima desde el UE (15) al NB (11, 11', 11''), estableciendo el RNC (12, 12', 12'') al menos un canal compartido de DL de alta velocidad, llamado tambien HS-DSCH, que permite trafico de datos en el enlace descendente con una velocidad de datos maxima determinada desde el NB (11, 11', 11'') al UE (15), comprendiendo el NB (11, 11', 11'') un planificador del HSDPA, llamado tambien HS-S, que planifica la velocidad de datos para el trafico de datos en el DL a traves del HS-DSCH y un planificador de EUL, llamado tambien EUL-S, que planifica la maxima velocidad de datos para el trafico de datos en el UL a traves del E-DCH, intercambiando el NB (11, 11', 11'') información acerca de la velocidad de datos entre el HS-S y el EUL-S, caracterizado porque el NB (11, 11', 11'') monitoriza el cociente, llamado tambien Q, entre la velocidad de datos en el DL y la velocidad de datos en el UL, cuando Q cumple determinadas condiciones de trafico el HS-S ylo el EUL-S cambian la asignación ylo el manejo de prioridad del UL ylo los recursos del DL, y donde las determinadas condiciones de trafico que cumple Q se refieren a una comparación entre Q y un cociente Qant, siendo Qant un calculo previo de Q.

    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 receiving data from a network via a base station and assigning a mobile station to a packet channel having an active mode and a variable fast page mode. Packet data is exchanged in the active mode until a first inactivity timer expires. The base station and mobile station are then switched to a variable fast page mode in which additional packet data can be exchanged, wherein the variable fast page mode has a greater delay between transmission opportunities than the active mode. The variable fast page mode schedules specific time slots which are monitored for the transmission and receipt of successive packets. In addition, the periodicity of future time slots can vary based on the delay between the successive packets. The mobile station remains in variable fast page mode until the expiration of a second inactivity timer or at the reception of a transmission opportunity and subsequent data transfer to or from the mobile station.
