Patent

CA 2182598

This invention provides a cellular radiotelephone system which includes mobile stations which may be remotely programmed from a customer activation system to effect activation and other programming needs. Mobile stations are manufactured in a blank form that causes them to operate only in an inactive state. During activation, information describing the mobile station's electronic serial number (ESN) is collected along with area of use information. A mobile identification number (MIN) is assigned in response to the area of use information. A page message is directed to the mobile station operating in its inactive state, but the page message references the ESN of the mobile station. While inactive, the mobile station detects pages directed to its ESN. A remote programming session is then performed wherein digital user-specific programming data, including the newly assigned MIN, are transferred to the mobile station over a voice channel using a control channel protocol. A novel cellular telephone which is configured for such remote activation, as well as the methods of remote activation are also provided.

Un système radiotéléphonique cellulaire (10) comprend des postes mobiles (28) qui peuvent être programmés à distance à partir d'un système d'activation utilisateur (12) permettant l'activation et répondant à d'autres besoins de programmation. Les postes mobiles (28) sont fabriqués sous une forme non programmée qui ne leur autorise qu'un fonctionnement limité en mode inactif. Au cours de l'activation, des informations se rapportant au numéro de série électronique (ESN) du poste mobile sont rassemblées, ainsi que des informations relatives à la zone d'utilisation. Un numéro d'identification de poste mobile (MIN) est attribué en réponse aux informations relatives à la zone d'utilisation. Un message de recherche est acheminé vers le poste mobile en mode inactif, mais ce message de recherche se réfère à l'ESN dudit poste. Dans ce mode inactif, le poste mobile (28) détecte les recherches concernant son ESN. Une séance de programmation à distance s'effectue alors, au cours de laquelle des données de programmation numériques, spécifiques à l'utilisateur, et comprenant le MIN récemment attribué, sont transférées vers le poste mobile (28) par voie téléphonique au moyen d'un protocole de voie de commande (80).
