Abstract: A protocol stack for an ad hoc type network comprises existing modules from third generation 3GPP architectures, a radio access plane, a mobility management module and a radio resource control module, said ad hoc type network being able to be organized into several groups—or clusters, a group corresponding to a grouping of radio resources for a given coverage area, and: a routing module arranged between the management module and the radio resource control module; a part of the mobility management being managed in the access plane in order to manage transfers, or handovers, between the groups, in the case of a network that is organized into groups of users or “clusterized”; the module manages handover decisions and radio resource management; said protocol stack additionally comprising, an L2RTP layer suitable for processing the radio-level regenerative relaying at the level of a data packet; a security plane for isolating security functions.

Abstract: A data management device for a communication installation including at least one base station having resources and at least one terrestrial node connected to a core network and to the base station to control its resources via an interface includes a control device coupled to a traffic source and to the interface and able to take local control, on command, of at least a portion of the resources of the base station, instead of the node, to enable transfer of data between the traffic source and the base station.

Abstract: The invention concerns a radio communication terminal, comprising first means for transmitting/receiving RF signals to communicate in a cellular radio communication network, said first means being in standby mode when no communication is set up in the cellular network with another terminal or with the network itself. The invention is characterized in that the terminal comprises second means for receiving at least one carrier dedicated to collective data of multimedia contents, said second means being activated only when the first means are n standby mode. The invention also concerns a method for broadcasting and receiving collective data, as well as a system for broadcasting multimedia contents.

Abstract: A method is dedicated to communications management for a random access communications network, in which time intervals are broken down into access slots, and during each access slot, a network terminal can transmit an access request to the network associated with a message that it wants to transmit, and comprising at least one processing device that introduces a long time for transmission of an access request acknowledgement message. This method consists of periodically sending acknowledgement messages to terminals, each message comprising positive acknowledgement information associated with each authorized access slot. Thus, when a requesting terminal receives an acknowledgement message later than an access request transmitted during a given access slot, it can transmit the message associated with its access request.

Abstract: A device (D) is dedicated to communication management in a base station (SB) of a random access communication network.

Abstract: A communication network including at least one piece of communication management equipment (SG) having a management component (MG) in charge of generating reference signals to be transmitted in a signaling channel to communication terminals (UE) connected thereto, and provided, along with each of the terminals (LIE), with an internal time reference which is defined in relation to a time set of a satellite positioning system (CS). The management component (MG) is also configured in such a way as to be able to generate a message including information representing the time of transmission of a reference signal in relation to the time set with a view to the transmission thereof to the terminals (UE) in a signaling channel.

Abstract: A processor device (D) is intended to be installed in a radio communication terminal (UE) adapted to be connected to a radio communication network having a go channel for broadcasting data from said network to terminals (UE) and a return channel dedicated to transmitting data from the terminals (UE) to said network, characterized in that it comprises processor means (MT) adapted to extract from control messages broadcast by said network on the go channel parameters for access to said return channel and to generate data messages to be transmitted to said network on said return channel as a function of said access parameters and not necessitating systematic acknowledgement on said go channel.
