Abstract
L'invention concerne un procédé et un appareil de synchronisation de dispositifs dans des sous-systèmes de stations de base MTA utilisant des connexions de canaux virtuels MTA spéciales. L'invention permet une connexion à débit constant élevé vers les stations d'émission réception de base (BTS) via le nuage MTA destinée essentiellement à la synchronisation. Le procédé de l'invention consiste à établir une connexion de canal virtuel à débit constant élevé vers chacun des dispositifs distants à partir du dispositif émetteur et à diffuser des cellules de données vers la pluralité de dispositifs distants, destinées à être traitées par la pluralité de dispositifs distants, afin de déduire une fréquence d'horloge sur laquelle ils se synchronisent. Les dispositifs distants comprennent des stations d'émission réception de base (BTS). Le dispositif d'émission (1210) est un dispositif à fonction d'interconnexion, lequel peut être un transcodeur. Le procédé permet la synchronisation d'horloges par la disposition d'un horodateur résiduel synchrone, au moyen d'une analyse pour déduire le temps d'arrivée des cellules de données, et par détermination d'une capacité disponible du tampon puis réglage des horloges de la pluralité de dispositifs distants en réponse à la capacité disponible du tampon.
