mobile phone remote diagnostics and repair method using the wireless communication module

摘要

PURPOSE: A remote test and repair method for a cellular phone using a radio communication module is provided so that the cellular phone can be remotely tested and repaired by performing the radio communication between a PC and the cellular phone having the radio communication module. CONSTITUTION: An RF transmitting unit(211) modulates and amplifies a radio communication data packet into a predetermined frequency band. An RF receiving unit(212) restricts amplification of the frequency signal noise, amplifies the frequency band signal, and applies the low frequency band signal to a baseband processing unit(213). The baseband processing unit(213) adds an access code and header to the HCI data packet from a cellular phone control unit(221), varies the packet format to a radio communication data packet, performs the radio communication in the frequency band, varies the data packet from the RF receiving unit(212) to the HCI packet, and applies it to the cellular phone control unit(221). A link control unit(214) controls a Bluetooth module(210) according to a command packet from the cellular phone control unit(221), and transmits the demand and result information of a master to the cellular phone control unit(221). On the other hand, a cellular phone unit(220) includes the cellular phone control unit(221), a memory(222), a key input unit(223), a display unit(224), a BBA(baseband analog)(225), an RF transmitting unit(226), an RF receiving unit(227) and a duplexer. Accordingly, the PC and cellular phone having the Bluetooth can perform the radio communication, to remotely test and repair the cellular phone.
