Abstract: A power supply device for supplying power via internet network comprises a power supply unit and a power consumption unit. The power supply unit comprises a power source unit and a first processing unit. The power source unit provides a first voltage with a first power and a second voltage with a second power. The first processing unit detects a connection status of the power supply unit for controlling the power source unit to provide the first voltage, and controlling the power source unit to provide the second voltage according to a control signal. The power consumption unit comprises a connecting unit and a second processing unit. The connecting unit is for connecting the power source unit and the first processing unit. The second processing unit receives the first voltage via the connecting unit and provides the control signal according to the first voltage.

Abstract: A femtocell in communication with a centralized server and a communication terminal obtains an available frequency range of a telecom operator via the Internet, detects communication parameters of neighboring femtocells and macrocells according to the obtained available frequency range, and randomly generates a set of communication parameters suitable for the femtocell according to the detected communication parameters. The femtocell further requires the centralized server to confirm availability of the set of generated communication parameters, and employs the generated communication parameters to communicate with the communication terminal if the set of generated communication parameters is available.

Abstract: A system and method for remote administration of a mobile phone includes a administrating terminal, and a transmitting device connected to the administrating terminal. The administrating terminal reads an identification number and a phone number of the mobile phone, sets functions of the mobile phone to be administrated, and generates a control command. The transmitting device wirelessly transmits the control command to the mobile phone according to the phone number, receives a acknowledgement from the mobile phone when the identification number of the control command matches an IMEI code of the mobile phone, and transmits the acknowledgement to the administrating terminal. The administrating terminal remotely administrates the mobile phone according to the control command.
