CA 2563506

In a wireless communications network (100) comprising a base station subsystem controlling at least one network cell (BSC1,BTS1,CELL1;BSC2,BTS2, CELL2,BTS3, CELL3,BTS4,CELL4), and in which the base station subsystem communicates with mobile stations (MS1,MS2,MS3,MS5,MS7) in the cell through radio blocks, a method of distributing information contents received in data packets at the base station subsystem to the mobile stations, comprising: obtaining, starting from the data packets, radio blocks (400) to be transmitted through the network cell; labeling the radio blocks with a first radio link identifier, identifying a logic connection between a mobile station and the base station 1.5 subsystem (TF11); communicating the first radio link identifier to a first mobile station (MS1,MS3,MS5) in the network cell; and in case at least one second mobile station (MS2,MS7) in the network cell asks to receive the information contents, communicating thereto the first radio link identifier. The method further includes having the first mobile station and the at least one second mobile station assigned respective second radio link identifiers (MFl1,MFI2,MFI3,MFI5,MFI7), to be included in the radio blocks.

L'invention concerne un réseau (100) de communication sans fil comprenant un sous-système de station de base commandant au moins une cellule de réseau (BSC1,BTS1,CELL1;BSC2,BTS2, CELL2,BTS3, CELL3,BTS4,CELL4), le sous-système de station de base communiquant avec des stations mobiles (MS1,MS2,MS3,MS5,MS7) de la cellule par l'intermédiaire de blocs radio. L'invention concerne également un procédé de distribution de contenus d'information reçus par paquets de données au niveau du sous-système de station de base aux stations mobiles. Ledit procédé consiste à obtenir, à partir des paquets de données, des blocs radio (400) destinés à être transmis à la cellule de réseau, à étiqueter les blocs radio à l'aide d'un premier identificateur de liaison radio, à identifier une connexion logique entre une station mobile et le sous-système de station de base (TF1¿1?), à communiquer le premier identificateur de liaison radio à une première station mobile (MS1,MS3,MS5) de la cellue de réseau, et au cas où au moins une seconde station mobile (MS2,MS7) de la cellule de réseau demande à recevoir les contenus d'information, à lui communiquer le premier identificateur de liaison radio. Le procédé consiste également à attribuer à la première station mobile et à la seconde station mobile des seconds identificateurs de liaison radio respectifs (MFl¿1?,MFI¿2?,MFI¿3?,MFI¿5?,MFI¿7?), inclus dans les blocs radio.
