| 摘要 |
The invention relates to a control device (D) which is installed in a data transmission control station (SC) of a communication network comprising at least one communication satellite (SA) and terrestrial communication stations (RE) which are used for the wave transmission of data to radio communication terminals (T1-T4) located in the terrestrial radio cells (C1-C8) of the network. The inventive device (D) comprises control means (MC1) which, when groups of data are to be transmitted to radio terminals (T1) located in at least one destination cell (C6), are used to: (i) subdivide the groups into first and second subgroups; (ii) form a first series of first subgroups and a second series of second subgroups; (iii) order the transmission of (a) the first series to the satellite (SA) and (b) the second series to each destination terrestrial station (RE) associated with a destination cell (C6); and (iv) synchronise the respective transmission times of the satellite (SA) and of each destination terrestrial station (RE), such that each of the radio terminals (T1) can receive each first subgroup of a data group that is intended for same for a period of time that is different from that during which it must receive the second subgroup of the same group. |
