Abstract: A protecting structure of an uninterruptible power supply prevents the uninterruptible power supply. The uninterruptible power supply device has a switch with a switching piece. The protecting structure includes a chassis, a sensor and a cover body. The chassis has an opening slot, the uninterruptible power supply device is installed in the chassis, and the switching piece is disposed corresponding to the opening slot. The sensor is provided on a side of the opening slot of the chassis and electrically connected with the uninterruptible power supply device. The cover body includes a cover plate and at least one blocking member connecting with the cover plate. The cover plate covers the opening slot, wherein the switching piece ejects the blocking member to expose the opening slot when the covered switching piece is switched from a first position to a second position.

Abstract: A network selection method automatically selects a communication network for a multi-mode mobile communication device, which has operability in two or more communication networks. Plural of digit map strings and a network priority setting are provided and stored in the mobile communication device. An input phone number is compared with all the digit map strings to obtain a match result. A communication network is selected by the mobile communication device among two or more communication networks based on a current network status, the match result, and the network priority setting.

Abstract: A method for managing incoming calls for a dual mode phone, comprising steps of: receiving an incoming call from a terminal; processing the incoming call and generating a prompt message to notify a user of the dual mode phone of the incoming call; determining whether the user accepts the incoming call; determining whether the dual mode phone is idle, if the user accepts the incoming call; determining whether a type of the incoming call matches with a current call mode of the dual mode phone if the dual mode phone is idle; switching from the current call mode to another call mode matching with the call mode of the incoming call if the type of the incoming call does not match with the current call mode of the dual mode phone; and establishing communication between the terminal and the dual mode phone.

Abstract: A mobile device for communicating in a first network or a second network includes a user interface (10, 10?), a call routing module (20, 20?), a network interface (60, 60?), a first communication module (30, 30?), a second communication module (40, 40?), and a phonebook management module (50, 50?). The call routing module is connected to the user interface for choosing a communication path. The network interface is used for connecting the mobile device to the first network or the second network. The first communication module and the second communication module are respectively connected between the call routing module and the network interface such that the mobile device can be communicated via the first network or the second network. The phonebook management module is also connected between the call routing module and network interface, for storing a communication history of the mobile device.

Abstract: A mobile communication device (10) includes a Man-Machine Interface (MMI) module (310), a network connection detecting module (340), a message module (330), an automatic setting activating module (320), and a provision module (350). The MMI module saves preset network setting data and network setting modes. The message module is connected to the MMI module for transmitting messages. The network connection detecting module is connected to the message module for detecting network signals, generating network connection status messages, and sending the network connection status massages to the message module. The automatic setting activating module is connected to the message module for automatically establishing a network setting of the mobile communication device.

Abstract: A method for a digital subscriber line device to process dial string. The digital subscriber line device is coupled to a PSTN (public switched telephone network) and a VoIP network. First, a transmission is received by the digital subscriber line device. Then, the dial string of the transmission is compared with phone numbers stored in a PSTN digit map and in a VoIP digit map by a PSTN digit string processor and a VoIP digit string processor, respectively. The transmission is routed to the PSTN network when a phone number corresponding to the transmission is found in the PSTN digit map. The transmission is routed to the VoIP network when a phone number corresponding to the transmission is found in the VoIP digit map.

Abstract: A method for a broadband modem to process incoming calls. The broadband modem is coupled to a PSTN (public switched telephone network) and a VoIP network. First, an call is incoming by the broadband modem. Then, the broadband modem detects whether the incoming call is routed from the PSTN network or the VoIP network. When the incoming call is routed from the PSTN network, the broadband modem establishes a connection between a telephone coupled to the broadband modem and the PSTN network through a switch. When the incoming call is routed from the VoIP network, the broadband modem establishes a connection between the telephone and the VoIP network through the switch.

Abstract: A firmware upgrade method for a network device through a digital subscriber line. First, the network device transmits a request to a dynamic host configuration protocol server through a digital subscriber line. Then, information comprising a file server address and a query message are transmitted from the dynamic host configuration protocol server through the digital subscriber line to the network device in response to the request. The network device determines whether to upgrade the firmware of the network device according to the answer of the query message. If the network device determines to upgrade the firmware thereof, updated information about the firmware is downloaded from a file server corresponding to the file server address. Finally, the firmware of the digital subscriber line device is upgraded according to the updated information.
