Responsive to receipt at an originating switching node (12(1)) of an incoming call (100), a location request (send routing) message is sent to the home location register for the called mobile station. A routing request (provide roaming) message (104) is then sent from the home location register to the switching node (12(1)) identified by the home location register as currently serving the called mobile station (14(1)). If the mobile station is not authorized to receive service in the areas serviced by the serving switching node a subscribed not found message (214) is returned to the originating switching node. Otherwise, the serving switching node pages (108) for the called mobile station only in those areas it services which are also authorized to provided called mobile station service. Responsive to a paging acknowledgement (110), an appropriate routing number is assigned (112) and transmitted (114) back to the originating switching node. The assigned routing number is then used to establish a trunk connection (116) between the originating switching node and the base station controller for purposes of effectuating call delivery (118).
En réaction à la réception d'un appel entrant (100) au niveau d'un noeud de commutation de départ (12(1)), un message de demande de localisation (send routing) est envoyé au registre de localisation nominal destiné à la station mobile appelée. Un message de demande d'acheminement (provide roaming) (104) est ensuite envoyé du registre de localisation nominal au noeud de commutation (12(1)) identifié par le registre de localisation nominal comme étant en train de desservir la station mobile appelée (14(1)). Si la station mobile n'a pas le droit au service de réception dans les zones desservies par le noeud de commutation de desserte, un message Subscriber not found (214) est renvoyé au noeud de commutation de départ. Sinon, le noeud de commutation de desserte recherche (108) la station mobile appelée seulement dans les zones qu'il dessert et qui sont également admises pour la fourniture de service de station mobile appelée. En réaction à un accusé réception de recherche (110), un numéro d'acheminement adéquat est affecté (112) et retransmis (114) au noeud de commutation de départ. Le numéro d'acheminement affecté est ensuite utilisé pour établir une communication longue distance (116) entre le noeud de commutation de départ et le contrôleur de la station de base en vue de la délivrance (118) de l'appel.
