Abstract: The present invention discloses a data management method applied in a communication system. The data management method includes the steps of: receiving a data from a transmitting end; determining a specific user identification code corresponding to the data; and storing the data into a data group according to the specific user identification code. The step of storing the data into the data group according to the specific user identification code includes the steps of: determining if the data group allocated for the specific user identification code exists in the communication system; if the data group exists in the communication system, storing the data into the corresponding data group; and if the data group does not exist in the communication system, generating a new data group in the communication system and storing the data into the new data group.

Abstract: A wireless communication apparatus includes a voice-receiving module, a voice-text transforming module and a wireless communicating module. The voice-receiving module receives voice information. The voice-text transforming module transforms the voice information to corresponding text information. The wireless communicating module transforms the text information to at least one data packet and transmits the data package at a preset time.

Abstract: A motherboard includes a digital enhanced cordless telecommunication (DECT) circuit, a bus, and a data processing circuit. The DECT circuit receives a wireless signal to output data. The bus is electrically connected to the DECT circuit to transfer the data. The data processing circuit is electrically connected to the bus to receive the data and performs an operation on the data.

Abstract: A wireless communication system includes a charging base, a phone, a computer host and a wireless communication module. The charging base has a charging socket, a data transmission port and a wireless communication socket. The wireless communication socket is electrically connected with the data transmission port. The phone inserts in the charging socket of the charging base to be charged. The computer host is electrically connected with the data transmission port of the charging base through a transmission cable. The wireless communication module inserts in the wireless communication socket of the charging base and communicates with the phone according to a wireless communication protocol. When the phone transmits information, the wireless communication module receives the information and transmits it to the computer host through the data transmission port and the transmission cable.
