Patent

CA 2176590

A method of invoking and cancelling voice and data service between a mobile unit and a base station. Using a standard telephone system, the connection for a voice service and a data service is the same. With the introduction of the digital wireless link, the voice connection and the data connection are different. Therefore new dialing commands which indicate the intent of the connection are created. These commands can also be used to designate the intent of the call from a mobile unit capable of data and voice service but not capable of simultaneous voice and data service. They can also be used to invoke simultaneous voice and data services.

Procédé d'appel et d'annulation de services vocaux et de données entre une unité mobile et une station de base. Avec un téléphone classique les liaisons sont les mêmes pour un service vocal et un service de données, mais avec les liaisons numériques sans fil, les connexions vocales et de données diffèrent, ce qui a conduit à créer de nouvelles commandes d'appel qui indiquent le dessein de la connexion. Lesdites commandes peuvent également servir à indiquer le dessein de l'appel sur des unités mobiles capables d'assurer les deux services, mais non simultanément; elles peuvent en outre servir à l'appel simultané des deux types de services.
