Embodiment Construction

[0022] The method for CDMA / GSM dual-mode mobile communication is to add an auxiliary communication module of CDMA or GSM mode on the mobile phone suitable for GSM or CDMA system mode, including: a). Adding the auxiliary communication module of GSM mode on the mobile phone with CDMA mode The expansion interface of the module makes it have an expandable GSM mode; b). Add the expansion interface of the auxiliary communication module of CDMA mode on the mobile phone with GSM mode, so that it has an expandable CDMA mode; c). In the mobile phone with CDMA mode Add the auxiliary communication module of GSM mode to the mobile phone, and choose CDMA / GSM dual-mode communication; d). Add the auxiliary communication module of CDMA mode to the mobile phone with GSM mode, and choose GSM / CDMA dual-mode communication. The common parts of the two modes are: SIM / UIM card slot (4), speaker (7), liquid crystal display (8), microphone (9), battery board (10), radio frequency antenna (11), keyboard ...

Abstract

The method for CDMA / GSM dual-mode mobile communication and the communication equipment belong to the field of wireless communication equipment manufacturing. The main CPU on the main printed circuit board decides to start the main communication module or the auxiliary communication module according to hardware detection and judgment or user menu selection, a) if there is no auxiliary communication module, the main CPU automatically starts the main communication module on the main printed circuit board; b) if the auxiliary communication module) is inserted into the device, the main CPU automatically prompts the user to select the expected communication mode through the keyboard or special switch, and starts the The selected communication module, the main CPU cooperates with the power switch, audio switch, antenna switch and connector, and the common parts and the selected working module enter the selected GSM or CDMA working mode.

Description

Technical field: [0001] The invention relates to a communication method and communication equipment applicable to cellular frequency bands, mainly used to establish wireless communication with an IGSM network or an S95CDMA network, and belongs to the field of wireless communication equipment manufacturing.
