A mobile communications system (10) includes a first link and a second link (e.g., a circuit-switched link and a packet-switched link). When a mobile unit (20) is initialized in the mobile communications system (10), it identifies a first control signal, such as the digital control channel (DCCH) of an IS-136 system, of the first link. From information associated with the first control signal, the mobile unit (20) determines the existence of the second link. From information identifying a current frame structure in the first link, a pointer to the current frame structure of the second link can be derived.
Un système de communication mobile (10) comporte une première et une seconde liaison (ex. liaison à commutation de circuits et liaison à commutation par paquets). Lorsqu'une unité mobile (20) est initialisée dans le système de communication mobile (10), elle identifie un premier signal de commande, tel que la voie de commande numérique (DCCH) d'un système IS-136, de la première liaison. A partir des informations associées au premier signal de commande, l'unité mobile (20) détermine l'existence de la deuxième liaison. A partir des informations identifiant une structure de trame courante dans la première liaison, un pointeur de la structure de trame courant de la seconde liaison peut être dérivé.
