Radio communication terminal broadcasting et reception method and broadcasting system
First Claim
1. A mobile radio terminal comprising:
- first means (A) for transmitting/receiving radio frequency signals adapted to transmit/receive on paired data/voice carriers to communicate in a cellular mobile radio network, said first means being in a standby mode when no call is set up via the cellular network with another terminal or with the network itself, andsecond means (B) for receiving at least one downlink carrier dedicated to the broadcasting of multimedia content collective information, said second means being activated when the first means are in the standby mode, wherein a portion of circuitry of the first transmit/receive means is common to a portion of circuitry of the second receive means, wherein priority is assigned to calls in the cellular network and the switching means are adapted to switch the first transmit/receive means to an active state when a call arises in said network, and wherein the switch to an active state occurs regardless of whether multimedia content collective information is being received.

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.

12. A method of receiving collective information by a mobile radio terminal (20) comprising first radio frequency signal transmit/receive means for communicating in a cellular mobile radio network, said first means being in a standby mode when no call is set up via the cellular network with another terminal or with the network itself,
wherein said method comprises: -
a step of detecting the standby mode of the first transmit/receive means, and a step of activating reception of a carrier dedicated to multimedia content collective information when the standby mode is detected, wherein priority is assigned to calls in the cellular network, the first transmit/receive means is switched to an active state when a call arises in said cellular network, and the switch to an active state occurs regardless of whether multimedia content collective information is being received.

13. A system for broadcasting multimedia content to at least one terminal (20), wherein it comprises:
-
a service center (BM-SC) for grouping and multiplexing multimedia contents received from a plurality of sources (25, 25′
),a multimedia content concentrator (21) adapted to receive information transmitted by said service center and comprising transmit means (HTTR Tx 28) for transmitting a multimedia content carrier, and a retransmission satellite adapted to receive the latter carrier to convert it to a second carrier in the direction of at least one terrestrial repeater (24), said terrestrial repeater comprising means (30) for receiving said second multimedia content carrier and means (34) for extracting said multimedia content information from said second carrier to forward it on a third carrier adapted to be received by the terminal, wherein a second means is provided for transmitting said multimedia content information on a fourth carrier to the satellite adapted to convert from the fourth carrier to the third carrier, which the terminal is adapted to receive directly. - View Dependent Claims (14)
