Abstract

Cette invention se rapporte à un procédé utilisé dans un système de télécommunication cellulaire afin d'effectuer une opération de transfert (216) d'abonné (28) entre un premier système de communication à accès multiple et un second système de communication à accès multiple. A cet effet, une unité d'abonné en communication avec le premier système de communication à accès multiple mesure (206) un signal caractéristique d'un signal provenant du second système de communication à accès multiple, pour produire une valeur caractéristique de ce signal. En réponse à cette valeur caractéristique du signal, l'unité d'abonné est configurée pour communiquer avec le second système de communication à accès multiple. Ensuite, une opération de transfert (216) d'abonné est réalisée du premier système de communication à accès multiple au second système de communication à accès multiple. La valeur caractéristique du signal peut être constituée par l'intensité du signal. La valeur caractéristique du signal peut être mesurée à l'aide du récepteur (92) du premier système de communication à accès multiple.
