Plug-in type wireless communication terminal device

The present invention relates to a wireless communication terminal device, and more particularly to a wireless communication terminal device having a first communication protocol module built therein, and the second communication protocol module can be plugged in by a different communication protocol. The wireless communication terminal device is flexibly selected to be connected to a different communication network for communication connection.

In recent years, with the surge in the number of mobile phone users, the mobile phone communication network is often in an overloaded state, making the mobile phone in communication, which is similar to disconnection, poor call quality, network congestion, etc. The failure phenomenon has caused many inconveniences for users. Therefore, the manufacturer of the mobile phone has developed a dual-mode mobile phone in response to this problem. The so-called dual-mode mobile phone means that the mobile phone head can work at the same time. Under two wireless communication networks.

Taking a GSM/CDMA dual-mode mobile phone as an example, a GSM communication protocol module and a CDMA communication protocol module are respectively disposed therein, and a GSM card slot and a CDMA card slot are respectively disposed in the dual-mode mobile phone. A GSM smart card is inserted in the GSM card slot, and after the GSM communication protocol module confirms the user identification code for the GSM smart card, the dual mode mobile phone will be connected to the GSM network via the GSM communication protocol module. Communication connection, and when a CDMA network is required for communication connection, a CDMA smart card must be inserted in the CDMA card slot, and after the CDMA communication protocol module confirms the user identification code for the CDMA smart card The dual-mode mobile phone can pass the CDMA A protocol module that communicates with the CDMA network.

In addition, the GSM/CDMA dual-mode mobile phone can freely switch the communication protocol module of the GSM/CDMA dual-mode mobile phone according to the environment or actual operation requirements, so that the GSM/CDMA dual-mode mobile phone can be connected via the GSM network or The CDMA network is connected by communication. For example, when the GSM/CDMA dual-mode mobile phone is using the GSM network for communication connection, if the communication quality of the GSM network is not high or communication is bad, the GSM/CDMA dual mode mobile phone will immediately Switching to the CDMA network for communication connection, thus not only expanding the communication frequency of the dual-mode mobile phone, but also greatly improving the stability of the communication.

However, the communication protocol module of the general dual-mode mobile phone is pre-installed in the mobile phone, so that the scalability of the dual-mode mobile phone is extremely poor, and when the user moves in different areas, only the fixed one can be selected. Two kinds of communication networks cannot switch to other communication networks, so you can't choose better communication quality. Therefore, if a user has a mobile phone that is a GSM/CDMA dual-mode mobile phone, if you want to change to GSM/PHS dual In the case of a mobile phone, the user must re-purchase the dual-mode mobile phone with the GSM/PHS communication network function, which not only causes the user's financial burden, but also causes considerable inconvenience in carrying and using.

Therefore, how to design a dual-mode mobile phone, in a different area, free to choose the appropriate communication protocol module, in order to effectively solve the problem of mobile phone communication network disconnection, poor call quality and network congestion, that is, become The industry is striving to study an important topic of improvement.

In view of the above-mentioned shortcomings of the traditional dual-mode mobile phone, the inventors have developed and designed a plug-in type wireless communication terminal device based on the technical experience and accumulated professional knowledge over the years, and the wireless device of the present invention. The communication terminal device is free to select a suitable communication protocol module in different areas to effectively solve the shortcomings of the aforementioned conventional dual mode mobile phone.

The interface forms an electrical connection as a sub-module of the wireless communication terminal device. When the sub-module is plugged into the shared communication interface, the wireless communication terminal device reads the sub-transport via the shared communication interface. The communication protocol type of the module, and then the sub-module is used to establish a communication network, so that the wireless communication terminal device has a dual mode function, and the wireless The communication terminal apparatus may be different from the communication protocol by which the module is inserted, and elastically connected to choose to establish different communication networks, in order to meet the needs of different users.
