Title: Mobile communication system with re-connect function for non-speech data communications

Abstract: A mobile communication system for performing non-speech data communication through a radio zone between a mobile station and a base station includes a terminal, a mobile station, and an adaptor. The terminal transmits/receives non-speech data. The mobile station is accommodated in a base station through a radio zone. The adaptor is arranged between the terminal and the mobile station. The adaptor converts non-speech data to be transmitted/received to/from the terminal and a predetermined frame to be used in the radio zone through the mobile station, and performs error control in units of frames. The mobile station outputs a holding instruction to the adaptor in accordance with radio wave interruption in the radio zone, and outputs a holding cancel instruction to the adaptor in accordance with radio wave restoration. The adaptor instructs the terminal to pause non-speech data transmission/reception in accordance with the holding instruction from the mobile station, and pauses frame transmission/reception to/from the mobile station. The adaptor instructs the terminal to resume non-speech data transmission/reception in accordance with the holding cancel instruction from the mobile station, and resumes frame transmission/reception to/from the mobile station.
