Abstract: A service switching method, device and system for a local communication network are described. The method includes that: a current terminal receiving a service switching starting instruction sends running service information to a selected target terminal, and sends a service switching request message to a server; the server receiving the service switching request message sends service information to the target terminal; the target terminal extracts service progress time from the service information sent by the current terminal and the service information sent by the server respectively, calculates a time difference according to the extracted service progress time, and sends the time difference to the server; and the server regulates a progress of the service information sent to the target terminal according to the time difference to make the progress consistent with a progress of the service information sent to the selected target terminal by the current terminal.

Abstract: Disclosed are a transaction method, and a transaction system and device.

Abstract: Disclosed are a service switching method, system and server, and the method includes: service switching is implemented when a server determines that a service switching strategy is met according to switching information required for the service switching stored in the server or pooled in and reported by a service switching request. The system includes a server configured to implement service switching when determining that a service switching strategy is met according to switching information required for the service switching stored in the server or pooled in and reported by a service switching request. By means of the disclosure, the necessary switching information required for the service switching can be passed by a determined target terminal.

Abstract: The disclosed is a method and device for accessing data. In the method, a Bearer Independent Protocol (BIP) sends a data access instruction to a Universal Integrated Circuit Card (UICC) through a Serial Peripheral Interface (SPI); and the BIP gateway receives the data corresponding to the data access instruction from the UICC through the SPI. According to the technical scheme provided by the disclosure, access speed is improved for the user and large data transmission is implemented for the web server in the UICC.

Abstract: An implementing method and system for terminal communication are disclosed, the method includes: a first visitor location register judging, according to an identifier of a first terminal which initiates a communication, whether the first terminal has registered first real name system information in a network, wherein, the first visitor location register is the location register which is currently visited by the first terminal, the communication is initiated by the first terminal to a second terminal, the first real name system information includes the identifier of the first terminal and subscriber identity information of the first terminal, and the subscriber identity information corresponds to the identifier of the first terminal; and in a case when the first visitor location register determines that the first terminal has not registered the first real name system information in the network, terminating the communication initiated by the first terminal.

Abstract: An implementation method and system, main control device and smart card for information transmission are provided. The method includes: the smart card notifying the main control device of the operating mode supported thereby; the smart card receiving a clock frequency returned by the main control device, and if the main control device determines that the smart card can support an externally provided clock frequency, the clock frequency is a second clock frequency; judging whether the smart card itself can support the second clock frequency, and if true, the smart card and the main control device carrying out information transmission based on the clock control signal of the second clock frequency; otherwise the smart card carrying out the transmission based on the dock control signal of the first clock frequency, and the main control device carrying out the transmission based on the clock control signal of the second clock frequency.

Abstract: A method, a device and a system for displaying radio frequency identification application information are provided. The method includes: a Secure Digital Memory Card (SD card) running a Radio Frequency Identification (RFID) application to generate RFID application information, wherein the RFID application includes a RFID service program and a display application (S102); the SD card uploading the RFID application information to a terminal (S104); the terminal displaying the RFID application information according to the mode of communication with the SD card (S106). Based on the technical solution, the RFID application display is realized in the SD card, and the terminal can display the RFID application information in the SD card according to different communication modes of the SD card, thereby the problem that the RFID application running on the SD card cannot be displayed is solved and the application scope of the SD card is enlarged.
