Abstract

The invention relates to wireless communication field and discloses a double-standby wireless terminal. In the invention, two independent radio frequency unit share a baseband unit in order to realize the simultaneous standby of two numbers and lower cost. When the two radio frequency units support 2G or 3G respectively, one of the radio frequency units is put to time division multiplexing by the baseband unit if two protocol processing units both work under 2G or 3G protocol, in order to achieve the effect of simultaneous standby of two numbers or communication under one of the numbers. When the networks supported by the two radio frequency units are identical to the networks supported by the two protocol processing units, the two protocol processing units form two combinations with different radio frequency units respectively so as to support the simultaneous standby and the simultaneous communication of the two numbers. Being further simplified, such a terminal uses one radio frequency unit and one baseband chip only and supports SIM or USIM slot and 2G or 3G protocol simultaneously, thus the terminal can be simplified into single-baseband chip single-module double-standby wireless terminal of 2G or 3G system.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a technology in which two numbers in one wireless terminal can be on standby at the same time. Background technique [0002] Driven by technology, market and wireless mobile application business, the wireless mobile communication industry has developed rapidly, and mobile communication products have become a necessity for people's daily work and life. As mobile communication has more and more influence on people's life, there are more and more phenomena that a person needs two mobile phone terminals. For example, some people who often need to work in two places usually have a local Subscriber Identity Module (Subscriber Identity Module, "SIM") card in each of the two places in order to avoid expensive roaming charges, and use different SIM cards in different cities. SIM card. However, frequent replacement of SIM cards or carrying two terminals is very troublesome, and a du...
