Embodiment Construction

[0023] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] The dual-mode dual-standby mobile terminal described in the present invention mainly refers to a mobile terminal with TD-SCDMA as one of the modes, and the other mode can be any mode of GSM, or PHS, or CDMA, or WCDMA. terminal.

[0025] In the 3G frequency band division, the frequency bands of each mode are adjacent to each other. In this way, when a 3G-based dual-mode mobile phone implements calls during dual-mode and dual-standby, interference will be introduced, resulting in a decline in service quality. If the dual-mode standby mode is not adopted, but the dual-mode single-standby scheme is adopted, the terminal needs to be switched off and then switched on again, which will prevent the terminal user from experiencing the convenience of the dual-mode mobile phone.

[0026] In the case that the two...

Abstract

A calling out method of double-mode double-standby mobile terminal includes picking up calling number inputted by user onto display boundary of mobile terminal, checking mode of current calling by standby module after calling command is sent out, ejecting out mode selection menu to let user select one mode to launch out calling if that standby mode is double-mode double-standby is checked out and directly applying current standby mode to launch out calling if that standby mode is double-mode single-standby is checked out.

Description

technical field [0001] The invention relates to a dual-mode dual-standby mobile communication terminal in the field of 3G mobile communication, in particular to a method for a dual-mode dual-standby mobile communication terminal device with TD-SCDMA as one of the modes to realize calling out. Background technique [0002] At present, the existing dual-mode mobile phones are nothing more than GSM / PHS, CDMA / GSM and WCDMA / GSM, etc. Each manufacturer has different implementations of dual-mode, mainly including: [0003] If the frequency points of the two modes in the dual-mode are far apart and the mutual interference between them is low, then in this dual-mode mobile phone, dual standby is generally used, that is, both modes can be in the standby state, and one of them When making a call in one mode, it is not necessary to consider the radio frequency interference caused by another mode; [0004] If the frequency points of the two modes in the dual mode are relatively close, c...
