Abstract

The embodiment of the invention relates to the technical field of communication, and discloses an incoming call processing method and a terminal. The incoming call processing method comprises the steps of judging whether the terminal falls back to a preset cell in a 2G or 3G network or not; carrying out a cell switching instruction if the terminal does not fall back to the preset cell in the 2G or 3G network, and accessing a target cell in the 2G or 3G network, wherein the target cell is another cell different from the preset cell; reading an incoming call flag bit, and judging whether the incoming call flag bit is 1 or not; informing a network end of the target cell of reading incoming call data if the incoming call flag bit is 1, thereby enabling the network end to reestablish a call link with a calling end; and receiving an incoming call sent by the network end, and establishing the call with the calling end. According to the embodiment of the method and the terminal, when the terminal fails to fall back to the 2G or 3G network, an incoming call success rate can be improved.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a method and terminal for processing incoming calls. Background technique [0002] In order to meet the ever-increasing demand for wireless data services, operators have gradually introduced the fourth-generation mobile communication network, namely 4G, based on the existing network. If there is an incoming call under the 4G network and a voice call service is required, the terminal needs to fall back to the second-generation or third-generation mobile communication network, that is, the 2G or 3G network, and then make a call. This process is called circuit domain fallback (CSFB, Circuit Switched Fallback Packet System). However, when the terminal performs CSFB and falls back to the 2G or 3G network, abnormalities often occur, resulting in the inability to establish a call. Contents of the invention [0003] The embodiment of the invention discloses an incoming...
