Patent

CA 2267367

In a mobile communication system which includes mobile switching centers (6 to 8) which have TDMA signals and time slot sharing and frequency channel sharing time divided CDMA signals and has a controlling function of allocating the signals on a time base and a frequency base and wherein mobile stations (15 to 33) are radio connected to radio base stations (11 to 31), connected to the mobile switching centers, by a multiple connection system and said mobile stations having a high speed data transmission function can be radio connected to the radio base stations also by high speed data channels, information of time slots in frames of down-links transmitted from two adjacent radio base stations to one mobile station is provided with serial numbers by the mobile switching centers to which the radio base stations are connected, and hand-over processing is performed based on the serial numbers.

Cette invention se rapporte à un système de communication mobile, dans lequel on prévoit des centraux mobiles (6-8) ayant des signaux CDMA à division dans le temps, qui partagent les tranches de temps et les canaux de fréquence avec des signaux TDMA, et possédant une fonction de commande qui attribue ces signaux à des coordonnées temporelles et à des coordonnées fréquentielles, et dans lequel des stations mobiles (15-33) sont radioconnectées à des stations de base radio (11-31) connectées auxdits centraux (6-8) dans un système à accès multiples et dans lequel, ensuite, les stations mobiles (15-33) possédant des fonctions de transmission de données haute vitesse peuvent être radioconnectées aux stations de base radio (11-31) même par l'intermédiaire de canaux haute vitesse. Dans ce système, un nombre sériel est attribué par les stations mobiles connectées à deux stations de base radio adjacentes aux informations contenues dans chaque tranche de temps de la trame de chaque ligne descendante transmise à une station mobile à partir de ces stations de base radio et le traitement par commutation est effectué sur la base de ce nombre sériel.
