Abstract
A data communication system utilizing a cellular phone is composed of a radio base station, a cellular phone having a function of connecting to a network through radio communications with the radio base station to make data communications accompanied by error control using a CRC code, and a terminal connecting to the network by using the data communication function of the cellular phone to make data communications, wherein, when a message frame which is an error frame having a different CRC code is received from the radio base station, the cellular phone takes out and stores the data contained in the message frame and reproduces the thus stored data to output the data.
Claims11
A data communication system utilizing a cellular phone, comprising:
- a radio base station,
- a cellular phone having a function of connecting to a network through radio communications with the radio base station to make data communications accompanied by error control using a cyclic redundancy code (CRC), and
- a terminal connecting to the network by using the data communication function of the cellular phone to make data communications,
- wherein, when a message frame which is an error frame having a different CRC code from a normal data communication is received from the radio base station, the cellular phone takes out and stores the data contained in the message frame without transmitting the data to the terminal and reproduces the thus stored data to output the data.
