Abstract: The present disclosure discloses a method, device and system for negotiating authentication mode. A first negotiation request carrying an authentication mode supported by a terminal is sent to an authentication server, so that the authentication server determines and sends an authentication mode supported by both the authentication server and the terminal, where the authentication mode is determined according to an authentication mode supported by the authentication server and the authentication mode supported by the terminal in the first negotiation request. The authentication mode supported by both the authentication server and the terminal is received by the terminal from the authentication server. Therefore, according to the disclosure, a common authentication mode supported by both the authentication server and the terminal is negotiated before the authentication is performed.

Abstract: A method for upgrading antivirus software and corresponding terminal and system thereof are provided. The method includes: reporting, by a first operating system connected to a terminal, a first device port of the terminal to a computer when the computer is started; running, by the computer, a second operating system of the port via the first device port; loading, by the second operation system, a driver of a network communication device or the terminal, and downloading, by the second operation system, an update file of the antivirus software from a remote virus database server via the network communication device, and adopting, by the first operating system of the terminal, the update file of the antivirus software to update the antivirus software. The beneficial effects of the present invention lie in that the latest antivirus software can be updated when the computer is started, thus ensuring the system security and antivirus efficiency.

An elastic structure capable of enabling the antenna to extend out of the data card body and also retract into the data card body is disposed between the data card body and the antenna. The electronic device includes a device case provided with a device port and the wireless data card disclosed above in this disclosure, in which the wireless data card is disposed in the device case and relative to the device port, and the antenna is disposed relative to the device port. This disclosure is applied for transmitting wireless data communication signals.

Abstract: The present invention discloses a method of notifying an alert status. The method includes using at least two binary alert status indication fields to indicate alert status information; changing a value of the alert status indication field when alert information is changed; and periodically sending the alert status information. The alert status indication field in a interworking element of a beacon frame is extended so that the status of the emergency alert is detected, the change to the emergency alert status is reflected by the value of the extended alert status indication field, and the change to the emergency alert can be detected and handled in a timely manner.

Abstract: A communication terminal includes: an image or video collecting and generating module, adapted to collect and generate 3D image or video data; a communication module, adapted to send or receive image or video and generated 3D image or video data; and an image or video display module, adapted to display the 3D image or video according to the collected or received and generated 3D image or video data. An information system includes a 3D image or video information center. The 3D image or video information center further includes: a 3D image or video information relay, adapted to interact with the communication terminal; and a 3D image or video information server, adapted to store 3D image or video information and convert between 3D image or video information and SMS. The communication terminal features simple structure and good performance. The information system supports communication through 3D image or video information.

Abstract: A communication device is provided, which has a PCI Express interface and includes: an interface circuit board, configured to bear the PCI Express interface; a main circuit board, connected to the interface circuit board through soft link, and configured to transmit/receive and process data of the PCI Express interface; a guide rail, configured to bear the main circuit board, so that the main circuit board slides between a use position and an accommodation position through the guide rail; and an antenna, installed on the main circuit board, and located at different positions with the movement of the main circuit board. According to an embodiment of this invention, the antenna in the main circuit can be exposed out of a case of the communication device, or accommodated into the case of the communication device, thus being convenient for the storage and transportation of the communication device.

Abstract: A USB connector for connecting with a USB female comprises metal legs, a connecting line, a substrate and a rotating shaft assembly. One end of the metal legs connects with one end of the connecting line. The metal legs are formed on a surface of the substrate. The connecting line is fixed to the surface of the substrate. The rotating shaft assembly is fixed to the surface of the substrate. The present invention also provides a USB device. According to the USB connector and the USB device of the present invention, the metal legs are formed on the surface of the substrate so as to ensure the connecting strength of the metal legs. Since the size of the USB connector depends mainly on the substrate and as long as the thickness meets a requirement of inserting the USB connector into the USB female, the thickness of the USB connector and further the thickness of the USB device are reduced without compromising the function of the USB connector.
