Problems solved by technology

[0005] TD-SCDMA / GSM dual-mode dual-standby mobile terminal supports successful registration on TD and GSM networks at the same time, and can use TD and GSM networks for voice or data transmission services, but there is only one microphone and one earpiece on the dual-standby mobile terminal , and only one network mode can be used for calls at the same time
In the case that the business operations under the two networks cannot be performed at the same time, when the current network performs business operations such as calling and browsing, the voice call of another network mode can only be hung up or held.

Description

technical field [0001] The invention relates to a dual-standby mobile phone terminal, in particular to a method for switching a double-standby mobile phone terminal when a non-current mode number calls. Background technique [0002] WCDMA, CDMA2000 and TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, hereinafter referred to as TD) are all 3G standards. The 3G networks of the first two standards have been operated for a long time abroad and are already very mature. TD standard The network of China has also begun to build. The GSM (Global System for Mobile Communications, Global System for Mobile Communications) standard 2G network has large-scale construction both at home and abroad, and this network has a relatively wide coverage, stable operation, and a large number of user groups. Most cities in China have built PHS (Personal Handy-Phone System, personal mobile communication system) networks, and some other countries have built PHS networks. [0003] Ne...
