Abstract: A method for a wireless network, including a node and a first device covered by the node, the node acting as serving node for the first device, and the first device transmitting first data to the node over a first link, includes determining presence of a second device covered by the node, the second device transmitting second data to a serving node over a second link, determining radio quality of the first link, determining radio quality of the second link, and determining radio quality of a third link between the second device and the first device. If the radio quality of the third link is higher than the radio quality of the second link, the second device transmits the second data to the first device over the third link and the first device retransmits, over the first link, the second data to the node.

Abstract: A method of operating a wireless communications network is adapted to provide services to users exploiting a first and a second different radio communications technologies, for example, an enhanced general packet radio service network. The method includes: providing, in a user profile available at the network, a subscription indication adapted to indicate that the user has subscribed for being provisioned with the network services through the first radio communication technology, upon reception by the network of a capability indication from the user adapted to indicate to the network that the user supports the first radio communications technology, looking up the user profile for the presence of the subscription indication; and in case the subscription indication is not found, handling the user as if supporting the second radio communications technology but not the first radio communications technology.

Abstract: In a wireless communications network having a base station subsystem controlling at least one network cell, and in which the base station subsystem communicates with mobile stations in the cell through radio blocks, a method of distributing information contents received in data packets at the base station subsystem to the mobile stations, includes obtaining, starting from the data packets, radio blocks to be transmitted through the network cell, labeling the radio blocks with a first radio link identifier, identifying a logic connection between a mobile station and the base station subsystem, communicating the first radio link identifier to a first mobile station in the network cell, and in case at least one second mobile station in the network cell, asks to receive the information contents, communicating thereto the first radio link identifier.

Abstract: An acknowledged MBMS service in which a procedure for providing retransmissions of incorrectly received data blocks is performed, together with an outer coding of the data blocks to be transmitted to the MBMS MSs. A sequence of data blocks carrying information related to the MBMS service is encoded at a BSS (Base Station Sub-system) of the mobile network by an outer coding unit. After the outer coding, the resulting data block sequence is sent to the MBMS MSs. If a data block of the outer coded sequence is badly received by a number of MBMS MSs, corresponding negative acknowledgements (nacks) are sent by such MSs to the BSS. The MSs also notify the BSS, with a positive acknowledgement, if they succeed in outer code decoding the sequence of the MBMS carrying information data blocks, in spite of possible badly received data blocks.

Abstract: The behavior of a network for mobile ratio apparatuses is simulated in a work station having a data input capable of inserting data representative of a network scenario, a data output capable of making available data representative of results of the simulation of the network, and a simulation environment associated with the computer and capable of simulating the network on the basis of the network scenario and of generating and sending to the data outputs the data representative of the results. This environment has first objects representative of devices and/or physical elements belonging to the network to be simulated and second objects representative of processing modules separate from the first objects and capable of conditioning and activating the first objects on the basis of the network scenario to simulate the network.

Abstract: The present invention is related to a system for simulating the behaviour of a telecommunications network for mobile radio apparatuses and to the relating method. The system comprises an integrated simulation environment (30) having a modular structure based on interchangeable objects, that comprise a simulation engine (31) and a plurality of devices (34) representative of apparatuses as well as physical elements of the network. By virtue of its structure based on objects which are interchangeable and capable of being selectively activated, the system allows the simulation of networks for high complexity mobile radio apparatuses in terms of quantity of apparatuses and type of systems or networks. The system is easily expansible as a function of both the variation of the system or network types and the technological implementations available on the market.
