Abstract

Pour qu'un utilisateur d'un terminal mobile puisse appeler un autre utilisateur d'un terminal mobile à l'aide d'un nom ou d'un identifiant choisi librement sans connaître ni rechercher le numéro de téléphone mobile de l'appelé, tout en masquant son numéro de téléphone mobile, l'invention propose un procédé de communication entre deux terminaux mobiles (200, 300) par le biais d'une unité centrale (100) comprenant une unité de commande (150) et une unité de communication (160), les terminaux mobiles (200, 300) étant chacun enregistrés avec une première identité de communication (ComA-ID, ComB-ID) dans l'unité de commande (150). Une liaison vocale anonyme est ainsi possible entre deux abonnés, une liaison téléphonique étant utilisée pour la communication via le réseau de téléphonie mobile avec tous les avantages d'une liaison téléphonique en termes de qualité.
