The invention relates to a method for communicating between nodes of an ad hoc network including a database matching geographical zones and radio channels, at least one respective radio channel, called geographical radio channel, being selectively associated with each geographical zone in the database: detection, by at least one node, of its location; determination, by said node, of at least one geographical zone within which it is located, based on the detected location, and determination of at least one geographical radio channel selectively associated with said determined geographical zone; transmission and/or reception by said node of data to be relayed between nodes of the ad hoc network on said geographical radio channel thus associated with it.

Method of communicating in an ad hoc network, transmitting/receiving station and associated computer program

A method for sharing spectrum in a communication network, comprising at least two systems working in frequency ranges that can overlap at least partially and in one and the same geographic area, comprises at least the following steps: affiliating the first and second systems with a server; determining whether there is a constrained system and, if there is, assigning said constrained system a first spectral band, for a given geographic area; performing this assignment for all the geographic areas covered by the two systems; and identifying the non-constrained systems and, by applying sub-band priority and management rules, assigning, for each of the non-constrained systems and each defined geographic area, a spectral band for each of the systems, and in the case where it is impossible to find a spectral sub-band, generating an alarm.

Method and system for sharing radio spectrum

A method for data processing, in an ad hoc radio communication network including a set of radio communication stations each forming a node of the ad hoc network, in order to create a group of stations, including the following steps: creating by a first station of a first message indicating the network address of the group and the network addresses of the stations in the group; transmitting from all of the stations in the ad hoc network, the said first message; upon receipt of the said first message by the said station, each station: records in a lookup correlation-mapping table, the network address of the group in correlation with the network addresses of the stations in the group; and if the network address of the said station is present among the network addresses of the stations in the group, records the network address of the group indicated in the first message as the group address of the said station.

Data processing method, in an ad hoc radio communication network, radio communication stations and corresponding computer programs

A communication node receiving and/or transmitting radio communications according to a first and a second communication protocol simultaneously. It has a first, second, respectively digital processing stage performing operations specific to the first, second protocol, respectively, operating in parallel. A first, second receiving stage, respectively, operating according to the first, second communication protocol, a transmission stage operating according to the first and second communication protocols, having a digital/analog converter converting a digital signal provided by the first or second digital processing stage into an analog signal, a modulator modulating said analog signal, an amplifier and a radiofrequency transmitter transmitting a radio frequency signal corresponding to the modulated analog signal, and a control module selecting, based on a rule and a detected event, the first or second communication protocol and commanding the transmission stage to operate selectively according to the selected protocol and no longer operate according to the non-selected protocol.

Communication node suitable for receiving and/or transmitting radio communications according to at least one first and one second communications protocol simultaneously

A communication method between two distinct networks with radio communication nodes, includes the following steps: collecting geographical location information for the nodes of the first and second network, deducing a geographical coverage area of the first and second network as a function of geographical location information; determining an intersection zone of the geographical coverage areas; identifying, as a function of the collected location information, nodes of the first and second network, located inside said intersection zone; and sending said nodes of the first identified network data indicating the collected geographical locations of the nodes of the second identified network.

A method for controlling communications within an ad hoc mobile network includes a plurality of terminals having the slave function and/or the master function, said slave terminals also including a slave orchestration system, said master terminals also including a master orchestration system. The slave orchestration system includes at least one network test module, a module for controlling communications, and a database of communications to be set up and an administration module. The master orchestration system includes at least one network test module, a module for controlling communications, a database of communication requirements, a decision engine, a database of current communications, a rule database for prioritizing communications, and an administration module. The master orchestration system is suitable for defining which communications between the slave terminals are authorized according to said prioritization rules and for notifying the slave orchestration systems of the slave terminals of their authorization to set up a communication or of the need to interrupt a communication previously set up.

System and method for controlling communications in an ad hoc mobile network

In order to establish a packet communication between a first server (SS) connected to a packet network (RP) and a service entity (ES) capable of communicating without a subscriber identification module in a radiocommunication network (RR), the service entity transmits an identifier (IdEs) of the service entity (ES) to a second server (SO) that determines an address (Ads) of the first server based on the received service entity identifier. The second server transmits the determined address of the first server to a gateway that interconnects the radiocommunication network and the packet network. The gateway establishes a communication between the service entity and the first server based on the address of the first server.

The apparatus (D) is dedicated to managing momentarily radio link interruptions between mobile stations (MS-i) and at least one radio network controller (BSC) of a radio access network (RAN) of a communications network. The apparatus comprises firstly detector means (DM) capable of detecting a radio link interruption between a mobile station (MS-i) and a radio network controller (BSCn), and secondly control means (CM) capable, on an interruption being detected by the detector means (DM), of ordering the radio network controller (BSCn) to suspend the radio link and then to attempt reactivate the radio link in application of a selected timetable.

Method to provide wireless broadband communication to a high-speed movable vehicle

A method and system for synchronizing terrestrial nodes equipped with GNSS (Global Navigation Satellite System) receiver belong to a terrestrial network. Synchronization is achieved by selecting terrestrial node to be synchronized to form a synchronization zone. The clear sky view solid angle shared by the terrestrial nodes is determined. The terrestrial nodes acquire a rough time reference sent by a satellite that can be viewed by the terrestrial nodes in the clear sky view solid angle. A common synchronization date is determined for all the terrestrial nodes. And, at the common synchronization date all the terrestrial nodes acquires a predefined sequence from the satellite. The terrestrial nodes uses this sequence to adjust the reference time.
