A method for use in multicellular communication network system of the type having base stations and a plurality of remote stations. The method achieves reliable and fault tolerant synchronization between the stations in a call when a frequency hopping technique is used. The method includes steps for acquiring the frequency hop sequence by remote station and tracking the frequency hop sequence after acquisition in order to stay in synchronism. The method also provides for recovering from loss of synchronism and for staying in synchronism.
L'invention est une méthode de connexion pour réseaux de communication multicellulaires ayant des stations de base et une multiplicité de stations éloignées. La méthode de l'invention permet d'obtenir une synchronisation fiable insensible aux défaillances entre les stations dans une communication utilisant une technique à sauts de fréquence. Elle comprend des opérations de saisie des suites de sauts de fréquence par la station éloignée et de poursuite de ces suites après leur saisie pour conserver le synchronisme. Elle est également dotée de mécanismes de recouvrement du synchronisme après une dérive et de stabilisation du synchronisme.
