A method and apparatus for operating a wireless telecommunication system utilizing code division multiple access (CDMA) over-the-air with a Global System for Mobile (GSM) communications A-interface based network is described. A CDMA radio frequency (RF) signal interface provides a bi-directional interface to a subscriber unit (50), and a Global System for Mobile (GSM) communications A-interface SS7 transport provides a bi-directional interface with GSM mobile services switching center (MSC) (52). Additionally, a transparent message transport (44) is provided over which signaling messages defined in the GSM A-interface protocol are exchanged between the GSM MSC (52) and a subscriber unit (50).

Procédé et dispositif servant à mettre en service un système de télécommunications radio utilisant un accès multiple par différence de code (AMDC) combiné "par les airs" à un réseau basé sur une interface-A de système global de communications mobiles (GSM). Une interface de signal radiofréquence (RF) AMDC constitue une interface à deux sens pour une unité d'abonné (50) et un transport SS7 d'interface-A de GSM constitue une interface à deux sens avec un centre de commutation de services mobiles GSM (52). De plus, un transport de message transparent (44) permet d'échanger par son intermédiaire des messages de signalisation définis dans le protocole d'interface-A de GSM, entre le GSM MSC (52) et une unité d'abonné (50).
