Problems solved by technology

The fly in the ointment is: first, this technical solution is not suitable for dual-mode mobile terminals composed of CDMA and TD-SCDMA; second, because there is a network signal discriminator between the signal end of the antenna and the main CPU, the network signal discrimination trigger response efficiency Low, directly affects the response between CDMA and TD-SCDMA

Abstract

The invention relates to a dual mode mobile terminal composed of CDMA and TD-SCDMA communication modules. The dual mode mobile terminal comprises a dual mode communication module, a main CPU, a memory, a keyboard, an interface, an antenna and a power source. The dual mode mobile terminal is characterized in that the dual mode communication module is respectively a CDMA communication module and a TD-SCDMA communication module; a network signal discriminator is arranged between the signal terminal of the antenna and the main CPU; a network signal identifying software package is embedded in the memory. The dual mode mobile terminal has the advantages that firstly, the used of the dual mode mobile terminal in a mobile communication device for both CDMA communication and TD-SCDMA communication is realized; secondly, the responding speed of the communication module is high, the responding time is short, and defaults in the prior art are avoided.

Description

technical field [0001] The invention relates to a dual-mode mobile terminal composed of CDMA and TD-SCDMA communication modules, belonging to the field of mobile terminal equipment manufacturing. Background technique [0002] Patent No. 02101734.4, titled "CDM / CDMA dual-mode mobile communication method and communication device", this device is based on the existing CDMA main communication module or CDMA main communication module mobile phone, and adds a CDMA main communication module or CDMA main communication module. The auxiliary communication module of the communication module conversion work, add a group of switch and connector that can connect the exchange data of the main CPU (including all common parts) and the main communication module to the auxiliary communication module in parallel. The main function of this group of switches (power switch, audio switch, antenna signal switch) and the dedicated connector is to connect the corresponding signal data to the selected ...
