Method for displaying incoming caller identification information in call forwarding

Abstract

The invention discloses a method for displaying caller identification information in call forwarding. The method includes the following steps: when the incoming communication terminal calls the called forwarding communication terminal, the communication network server sends the first signaling to the called forwarding communication terminal; the called forwarding communication terminal sends the second signaling to the communication network server; the communication network server Sending call forwarding signaling to the call forwarding communication terminal; the call forwarding communication terminal displays the incoming call information including the user identification information of the incoming call communication terminal.

Description

technical field [0001] The invention relates to call transfer technology, in particular to a method for displaying identification information of caller users during call transfer. Background technique [0002] Call forwarding, also called incoming call forwarding, is a service provided by telecom operators to communication users. After setting up call forwarding, incoming calls can be forwarded to other phone numbers. [0003] There are four main modes of call forwarding: [0004] (1) No answer transfer: if the user's mobile phone is unanswered (preset answering time, such as 30 seconds), then the call to call him is transferred to the user's preset phone number; [0005] (2) Unreachable transfer: If the user's mobile phone is turned off, not in the effective service area, or the signal is poor, and normal calls cannot be realized, all calls to him will be transferred to the phone number preset by the user; [0006] (3) Transfer when busy: also called transfer when busy, ...

AI Technical Summary

Problems solved by technology

[0005] (2) Unreachable transfer: If the user's mobile phone is turned off, not in the effective service area, or the signal is poor, and normal calls cannot be realized, all calls to him will be transferred to the phone number preset by the user;

Although it solves the technical problem of displaying the caller name of communication terminal A on communication terminal C, its technical solution requires communication terminal B to store the address book information in the memory of the network side. Get user information and send it to communication terminal C for display

The defect of this technical solution is that the address book information saved on the network end is not synchronized with the communication terminal, resulting in inaccurate information on the network end, and because the address book information needs to be stored on the network end, it cannot save space
