Abstract: A data transmission method and a base station in a telecommunication system are provided. The base station comprises a first transmitter for transmitting a downlink packet transmission, a first receiver for receiving uplink packet transmission, a first controller for checking whether a packet is received successfully, thus obtaining a correct packet, a second receiver for receiving, from at least one other base station, a packet the at least one other base station has successfully received from the uplink direction, a second controller for combining a packet unsuccessfully received from the uplink direction with the at least one packet received from the at least one other base station, and a second transmitter, for sending a correct packet further to other parts of the telecommunication system.

Abstract: A method includes receiving on an uplink communication path one or more packets from a user equipment, and determining radio link resources to be allocated on the uplink communication path for the user equipment. The determination is based at least in part on an information content of the one or more packets. The determined radio link resources are allocated. Another method is disclosed including receiving at a network access element on a first uplink communication path a bandwidth request from a user equipment. The bandwidth request is for a second uplink communication path used for packet traffic from the user equipment to the network access element. Radio link resources to be allocated on the second uplink communication path for the user equipment are determined, the determination is based at least in part on the bandwidth request. The determined radio link resources are allocated on the second uplink communication path.

Abstract: The invention relates to mobility management in a mobile Internet protocol network. The network comprises a local mobility domain access router and a wireless access point operationally connected to the local mobility domain router, where the wireless access point is proxying a mobile node. Data packets destined to the mobile node and entering the local mobility domain router hold a proxy care-of address assigned to the mobile node as a routing address. The proxy care-of address is replaced with a local address assigned to the wireless access point, where the local address is invisible to the mobile node. With the procedure of the invention, the local mobility domain router acts as a wireless attachment point for the mobile node, thus decreasing signalling over the air interface when the mobile node moves in the network.

Abstract: The present invention relates to a method for configuring addresses in a packet switched data communication system. The method comprises providing a logical network with at least two network elements, a network element comprising at least one sub-element. The method further comprises configuring a temporary address for an interface of a sub-element, retrieving an identifier of the network element and defining an address for the interface of the sub-element by including the identifier of the network element to the temporary address.

Abstract: The invention provides an internet protocol based system comprising a plurality of entities. At least two of the entities are arranged to use SCTP for signaling therebetween. The SCTP signaling comprises connection identity information relating to a connection between at least two of said entities.

Abstract: The present invention describes a method, system and an interconnecting handler for sending connection-oriented or connectionless data between two endpoints in a protocol architecture. The transport protocol in the protocol architecture is in a preferred embodiment the Stream Control Transmission Protocol (SCTP). The present invention allows the setup and release of a connection when using a simplified protocol stack which is able to provide the same kind of services without using peer-to-peer messages like SCCP or SUA use. The present invention also enables discrimination between connection-oriented and connectionless services without peer-to-peer signalling.

Abstract: The present invention describes a method and system for local mobility management in which the mobility management taking place inside the mobile agent (MA) domain is hidden from the home agent (HA) and correspondent node (CN). In the method the mobile agent (MA) prefix information is broadcast over the air interface. An access router is implemented in the cellular access node (CAN). The cellular access node (CAN) also comprises a cellular access point (CAP). Proxy functionality is arranged to the cellular access point (CAP). Binding entries are created to the mobile agent (MA) so that only basic mobile IPv6 needs to be supported in the mobile node (MN).

The invention is also concerned with an intermediate amplifier used in such connections, the direction of the gain of the amplifier being controlled in accordance with the signal strength. The method comprises measuring the amplitudes of signals coming from different transmission directions, comparing the measured amplitudes of signals coming from different directions with each other, and controlling the gain of controllable amplifiers (12, 22) on the basis of the difference value of the amplitudes by applying a control voltage to the controllable amplifiers (12, 22) through reversephase control adapters (13, 23).
