Abstract: For transferring packets between a wireless data transfer device and a mobile communication network, temporary block flows are formed, and information is transferred in these block flows in one or more packet data traffic channels either in the first direction from the mobile communication network to the wireless data transfer device or in the second direction from the wireless data transfer device to the mobile communication network. In the method, information about the end of the block flow is set in a packet to be transmitted in a block flow when data transfer has stopped. When the transfer of packets in the first direction has stopped, at least one enquiry message is also sent from the mobile communication network to the wireless data transfer device.

Abstract: The present invention relates to a method and system for inspecting a session in a packet data network, wherein a set-up message is selectively routed to a predetermined server node (4001, 4002) and processed there. A media resource function (3021, 3022) is controlled based on the processing so as to bind incoming and outgoing data streams in order to relay the session via the media resource function. Thereby, a mechanism for providing charging, filtering and logging services for sessions, such as peer-to-peer chat sessions, is provided without requiring any new network entity or modification of existing network specifications.

Abstract: A communication method for transmission and reception of data blocks in a packet-switched communication network based on a cellular network (PLMN), between elements, which are used as transmitters and receivers and which comprise means for receiving data blocks, means for transmitting data blocks, and protocol means for forming and processing data. In the method, for the transfer of data blocks at least one transfer window is formed which, formed in the transmitter, is used as a transmit window, which, formed in the receiver, is used as a receive window, and which covers a maximum of k data blocks to be transferred. For optimizing the transfer of data blocks, said maximum size k is selected from a group consisting of several alternative maximum sizes, wherein said maximum size k is selected according to predetermined rules.

Abstract: A method of operating a mobile communication system supporting data transmission between a mobile station (MS) and a network in a number of different packet data protocols (PDPs) including a point-to-multipoint-multicast (PTM-M) protocol. PDP data is formatted and unformatted by a subnetwork dependent convergence protocol (SNDCP) according to the PDP of data. The PDP is identified to the SNDCP by a protocol identifier transmitted between the network and the mobile station. In order to allow a MS to receive a PTM-M in an IDLE state, a unique protocol identifier is permanently assigned to PTM-M transmissions whilst other identifiers are dynamically assigned to other PDPs by the network.

Abstract: A method is disclosed for operating a wireless telecommunication system for providing a Multimedia Broadcast/Multicast Service MBMS broadcast transmission from a network operator (10) to a mobile station (100). A first step determines a minimum bit rate requirement to broadcast a MBMS message and a number of radio blocks per time period that are required to satisfy the bit rate requirement. A second step allocates the determined number of radio blocks in accordance with a multislot transmission technique, wherein a plurality of time slots are used per frame, such that the mobile station is provided with at least one idle radio block between two active MBMS transmission periods. The at least one idle radio block may occur between two active MBMS radio blocks. A third step transmits the determined radio block allocation to the mobile station. In the preferred embodiment the step of determining may include a consideration of radio channel conditions and a multislot class of the mobile station.

Abstract: The invention relates to a method for transmitting data for a multimedia broadcast/multicast service (MBMS) from a radio access network of a cellular communication network via a radio interface to mobile terminals located in a radio cell supplied by said radio access network. The radio access network transmits paging messages on a common control channel. It is proposed that a dedicated channel is employed for transmitting the MBMS data, which dedicated channel is allocated in a way that the mobile terminals are able to receive simultaneously paging messages and the MBMS data. The invention relates equally to a corresponding network entity, mobile terminal and communication system.

In order to enable an efficient acknowledgement of downlink messages it is proposed that in a first step, at least two downlink messages are received at the mobile station from the communication network, of which at least two downlink messages reception has to be acknowledged. In a second step, the reception of the at least two downlink messages is then acknowledged in a single uplink message transmitted by the mobile station to the communication network. The invention equally relates to a corresponding mobile station, to a corresponding communication network and to a communication system comprising such a mobile station and such a communication network.

Abstract: A method for quickly de-allocating physical channels (PDCH) assigned to packet switched calls in a GPRS supporting GSM digital cellular telephone network. An PDCH de-allocation RLC/MAC control message is broadcast to listening mobile stations from a base station subsystem (BSS) and contains a temporary flow identity (TFI) which is recognised by the listening mobile stations (MS). The mobile stations respond by terminating packet switched data transmissions on the identified PDCHs. The RLC/MAC message also identifies the number of PDCH time slots which can be used before de-allocation must occur.

Abstract: In the invention, devices and a method are described by means of which it is possible to focus a camera (11) placed in a terminal (10), particularly in an image phone using radio communication, at a user of the terminal (10). The focusing of the camera (11) is implemented, e.g., by means of pattern recognition (61), whereupon the terminal (10), according to the invention, searches for the figure of an upper body (18) of the user of the terminal in the image field recorded by it. When this is located, a sub-section (62) of the section the camera (11) has stored in an image memory (64) is selected, the sub-section containing essentially the upper body of the user of the terminal. Alternatively, the camera (11) is focused, e.g., by means of electric motors, at the user or the user himself is asked to turn the terminal (10) in the required direction, e.g., with the help of indication characters transmitted on to the display of the terminal (10).

Abstract: The invention relates to a method for arranging the transfer of packets between a wireless data transfer device (MS) and a mobile communication network (NW). For transferring packets between the wireless data transfer device (MS) and the mobile communication network (NW), temporary block flows (UL TBF, DL TBF) are formed, and information is transferred in these block flows in one ore more packet data traffic channels (PDTCH) either in the first direction from the mobile communication network (NW) to the wireless data transfer device (MS) or in the second direction from the wireless data transfer device (MS) to the mobile communication network. In the method, information about the end of the block flow is set in a packet (302) to be transmitted in a block flow when data transfer has stopped. When the transfer of packets in said first direction has stopped, at least one enquiry message (306) is also sent from the mobile communication network (NW) to the wireless data transfer device (MS).
