  • the communication system obtains the stored called terminal number list associated with the personal number from the personal number server, and calls the numbers stored in the list one by one according to the set order. For example: The communication system first calls the user's office terminal number. If the office terminal is not answered or the call is busy within the set time threshold, the user's home terminal number is called. When the terminal in the home is still not answered or the call is busy within the threshold, the mobile terminal number of the user is finally called. During the sequential call of the entire communication system, if any of the called terminals of the user is connected because of the call ringing, such as: the user's office terminal is connected, the call is successfully connected even if the call is successfully connected, The system no longer calls subsequent terminal numbers.
  • the communication system may not care about the order of the called terminal numbers set by the user in the called terminal number list corresponding to a personal number. At this time, when the personal number is called, the communication system obtains the corresponding actual called terminal number from the list according to the personal number and simultaneously calls all corresponding actual called terminals. A user with the personal number can answer any one of them. The called terminal with an incoming call alert completes a simultaneous ringing call.

Abstract

L'invention concerne un procédé de déclenchement de service basé sur le numéro original appelé. Ce procédé comprend les étapes suivantes : (A) le rapport entre les informations de numéro original appelé et l'identification d'exploitation dans le terminal appelé est prédéterminé ; (B) le terminal reçoit le numéro original appelé correspondant à l'appel reçu à ce moment là ; (C) le terminal appelé évalue les informations de numéro original appelé, en fonction du rapport établi au cours de l'étape (A), de sorte à déterminer l'identification d'exploitation correspondante, et utilise l'identification indiquant le terminal appelé pour exécuter l'opération associée. Le procédé selon l'invention permet de résoudre le problème de décrochage par erreur du terminal appelé dans une communication impliquant un numéro personnel.
