Method for acquiring actual called terminal number by switch

Abstract

The invention discloses a method for acquiring actual called terminal numbers by a switch, which relates to a calling method for transmitting original called numbers. The invention provides a calling method for transmitting the original called numbers. By the method, a called terminal can realize the identification of the original called numbers. A calling terminal switch, according to the original called number, acquires the actual called terminal number corresponding to the original called number from the pre-stored corresponding relation between the original called number and the actual called terminal number; the calling terminal switch successively calls a called terminal switch according to the actual called terminal number and sends the original called number and the actual called terminal number of the calling to the called terminal switch; and the called terminal switch calls a called terminal according to the actual called terminal, and sends the original called number to the called terminal.

Description

Technical field: [0001] The invention relates to a calling method for transmitting an original called number. Background technique: [0002] At present, with the rapid development of communication technology and service applications, virtual number services such as One Number Reach appear. In the virtual number service, the operator sets a personal number for the user, and the user connects the personal number with the user's home terminal number, such as a home fixed telephone; office terminal number, a fixed telephone for work; mobile terminal number, such as a mobile phone, etc. The list of actual called terminal numbers is associated, and this association is stored in the personal number server. The user can also set the sequence of these actual called terminal numbers in the list, and call the numbers stored in the list one by one. For example, if the user's office terminal is connected, the call will be connected successfully, and the communication system will not ca...

AI Technical Summary

Problems solved by technology

When the communication system uses the personal number to call multiple called terminals preset by the user, the calling terminal switch can transmit the calling terminal number to the called terminal switch, and the called terminal switch that connects the call can obtain the calling terminal number , can realize the function of the called terminal to identify the number of the calling terminal, but it cannot realize the identification of the called personal number on the called terminal, for example: the called terminal can display the number of the calling terminal through the caller ID, but cannot display the number of the called terminal Therefore, the actual called user cannot be distinguished from the called terminal. In this way, in the application of virtual number services such as One Number, it may be wrongly connected because the called terminal cannot identify the actual called user; and then Situations that lead to the interception of ONLY calls: When the communication system calls the user’s preset multiple called terminals through the personal number, because the called terminal cannot recognize the personal number, it cannot determine the called user of this call; thus it may It will be intercepted by other users by mistake and the call will end
