A method is provided herein for operating a radiotelephone which is authorized to operate with a home cellular system that provides cellular services in a first geographical NPA area to originate a call. The method includes the first step of identifying the entry of a first three dialed digits and a later dialed digit, the first three digits being dialed prior to the later digit. The method includes the next step of determining, in response to the first three digits, whether the later digit is a final digit of a phone number by evaluating the first three digits to determine whether the first three digits define a connected NPA code which is remotely programmed into the radiotelephone, the connected NPA code corresponding to a geographical NPA area which overlaps or is adjacent to the first geographical NPA area. The method includes the final step of automatically transmitting an origination message when the later digit is the final digit of the phone number, the origination message conveying the phone number to a telecommunication network. A cellular radiotelephone is also provided herein for performing automatic number completion recognition. The cellular radiotelephone includes a keypad for detecting the entry of each of a plurality of dialed digits. The cellular radiotelephone includes a controller which is coupled to the keypad. The controller is configured to capture and analyze numeric values of the dialed digits. The controller also is configured to determine completion of a dialed phone number based upon the numeric values of at least some of the dialed digits and a determination as to whether the radiotelephone is roaming. The cellular radiotelephone includes a transmitter which is coupled to the controller. The transmitter is configured to send an origination message to a cellular communications network. That origination message conveys the phone number to the network.
Un radiotéléphone (10) simule le processus d'émission d'appels appliqué par des téléphones de réseaux téléphoniques terrestres. Une tonalité est générée (78) en réponse à un état de décrochage et disparaît lorsque le premier chiffre (54) est composé. Un processus de temporisation (84, 110) et un processus (100) d'analyse de numéros évaluent simultanément les chiffres composés afin de détecter la fin de la numérotation. Le processus (100) d'analyse de numéros peut identifier sept, dix et onze chiffres ainsi que des formats (64, 66, 52, 68) de numéros téléphoniques de longueur indéterminée. Le format à dix chiffres est reconnu en fonction de codes d'indicatifs régionaux connectés, programmés à distance (42). Pour la plupart des appels, le processus (100) d'analyse de numéros détecte instantanément le chiffre final (62) d'un numéro de téléphone. Dans quelques cas, le processus de temporisation (84, 110) détecte le chiffre final en déterminant une absence d'activité de numérotation pendant une durée prédéterminée. Lorsque le dernier chiffre (62) a été détecté, un message d'émission d'appels est transmis à un réseau cellulaire.
