摘要:
A method of bi-directional communication in a cellular mobile telecommunication network (2) includes a terminal (10) that receives signals transmitted by at least one radio base station (5,7) of a downlink network of the cellular mobile telecommunication network (2) and selects one serving transmitting radio base station (6) among one or more transmitting (5) or transceiving (7) radio base stations of the downlink network, wherein the downlink network operator selects one serving receiving radio base station (8) among one or more receiving radio base stations (3,7) of an uplink network which have received a signalling message (URRA) transmitted by the terminal (10). By way of the serving receiving base station (8) of the uplink network and the serving transmitting base station (6) of the downlink network, the terminal (10) establishes bi-directional connections over the cellular mobile telecommunication network (2).
摘要:
A system for generating and using (for storage and supply of) electric energy produced by modular direct-current electric energy sources, which includes: a system of interconnected modules for the production of direct-current electric energy which is positioned upstream of one or more systems for using electric energy through DC/AC conversion; a system of interconnected elements for storage and supply of electric energy produced by the energy production modules which is positioned upstream of the one or more systems for using electric energy; at least one electronic control unit, adapted to manage the interconnections among the modules and the interconnections among the elements, so that at least some of the interconnected modules can deliver electric energy directly to at least some of the storage and supply elements, and/or to the one or more systems for using electric energy, and so that at least some of the elements can supply electric energy directly to the one or more systems for using electric energy.
摘要:
A multi-antenna transmission process for providing down-link radio coverage from radio base station to mobile terminal in a network for radio mobile communications through a transmission system includes: at least one multi-radiator transmitting antenna, directed towards at least one mobile terminal; at least one database associated with at least one coverage cell of the mobile communications network and containing information about a position of the mobile terminal; processing means cooperating with the at least one multi-radiator transmitting antenna and the at least one database, the processing means being adapted to associate a transmission direction with the position of the mobile terminal, wherein the transmission direction is suitable for reaching the mobile terminal, including the steps of: a) detecting a position of the mobile terminal; b) storing the position into the at least one database; c) determining at least one transmission direction of at least one transmission beam from the at least one multi-radiator transmitting antenna to the mobile terminal depending on the position stored in the at least one database, wherein at least one of the transmission parameters that must be set in the at least one multi-radiator transmission antenna in order to transmit in the transmission direction is associated with the stored position of the mobile terminal.
