Abstract:
A method is performed at a computer server for enabling voice communication between two terminals through IM service. Upon receiving a message from a remote computer, the message including an IM identifier of a callee terminal user and a mobile device identifier of the terminal, the computer system updates an entry for the callee terminal user in a database. Upon receiving a request from a caller terminal user at a caller terminal to start voice communication with the callee terminal user, the computer server identifies the entry that includes the IM identifier of the callee terminal user and sends a voice communication request to a service control point (SCP) in a switched telephone network. The SCP then returns an IP address and a port number of the callee terminal and launches a call request against the callee terminal. The computer server establishes a voice communication channel between the two terminals.
Abstract:
In a method for control accessing to a communication account, a second terminal obtains the identification information of a first terminal, and sends the communication account information and identification information of the first terminal to the communication platform; the communication platform sends the communication account information to the first terminal based on the identification information. The first terminal sends the communication account information to a near-field communication (NFC) device and reads the communication account information stored in the NFC device when the distance between them is within the preset range. The first terminal then sends its identification information and the communication account information read from the NFC device to the communication platform. Based on communication account information and identification information, the communication platform controls the first terminal to log in by the use of communication account information.
Abstract:
A method, server and storage medium for verifying a transaction using a smart card are disclosed. A server receives a transaction request to perform a transaction with a user of the smart card. The transaction request includes identification information and encrypted data extracted from the smart card, and transaction information. The server determines a user account linked to the identification information. The server performs a first verification process to authenticate the smart card by verifying that the smart card possesses a correct decryption key corresponding to the identification information. The server performs a second verification process to authenticate the smart card by verifying that the encrypted data extracted from the smart card encodes stored data corresponding to the respective user account linked to the identification information. If the first and the second verification processes are successful, the server processes the transaction in accordance with the transaction information.
Abstract:
An information transmitting method and device, and an information receiving method and device are provided. The information transmitting method includes: obtaining authentication information; converting the authentication information into a binary sequence; encoding the binary sequence into optical signals based on a correspondence between a binary number and an optical signal; and transmitting the optical signals to a receiving device, wherein the receiving device receives the optical signals, obtains the authentication information carried in the optical signals, and performs an information authentication based on the authentication information.
Abstract:
The present disclosure provides a method, apparatus and system for readily and conveniently getting network access for a smart device. The method for network access for a smart device includes receiving, by a server comprising a processor and a non-transitory storage medium, a first identification identifying a wireless access point and a first terminal identifier; receiving a second identification identifying a smart device and a second terminal identifier; associating the wireless access point with the smart device if the first terminal identifier corresponds to the second terminal identifier, and sending the second identification for the associated smart device to the wireless access point. The wireless access point provides network access authentication information to the smart device so that the smart device can get access to a network provided by the wireless access point with the network access authentication information.
Abstract:
This application discloses a data communication method implemented at an electronic device. The electronic device obtains a sequence of data packets. Each data packet complies with a first data format corresponding to a network access protocol and comprises a respective header that further includes a data length field for specifying a length of the respective data packet. Data are then assigned to the data length fields of the sequence of data packets according to a second data format. The electronic device encrypts the sequence of data packets including the assigned data. The encrypted data packets are then sent to a receiver device that is communicatively coupled to the electronic device via a wireless network. The receiver device is configured to retrieve the assigned data from the data length fields of the data packets according to the first and second data formats and perform operations in accordance with the retrieved data.
Abstract:
A service terminal, which is communicatively coupled to a remote server, works with an offline user terminal to complete a service request initiated by a user of the user terminal. The service terminal repeatedly broadcasts a service message to neighboring user terminals until after receiving a service purchase request message wirelessly transmitted from a user terminal. The service terminal then suspends the broadcast of the service message and communicates the service purchase request to the remote server and receives a purchase confirmation message from the remote server. Next, the service terminal wirelessly transmits the purchase confirmation message back to the user terminal. From reading the purchase confirmation message, a user of the user terminal can tell whether the service purchase request has been completed successfully or not. If not, the service terminal then resumes the broadcast of the service message until after receiving another service purchase request message.
Abstract:
Methods, devices and systems for sharing information related to exercise/health activities are disclosed. A user terminal can acquire a device identifier associated with a health monitoring device, such as a monitoring wristband or a treadmill, through a communication program (e.g., an instant messaging application). The user terminal can communicate with a server of the communication program so that the server binds the device identifier with a user ID. The association of the user ID and the device identifier allows the user to share the health monitoring information from the health monitoring device with other users through the server. In addition, the connected users can participate in real-time competitions and share information related to the competition. The server also generates ranking lists or other sharing formats for the competition, improving user experience and making exercise and competition more attractive.
Abstract:
The present application discloses methods and devices for intercommunication between mobile terminals based on digital networks. A first mobile terminal may connect to a uniquely identified server based on a first terminal identifier corresponding to the first mobile terminal. In addition, the first mobile terminal may connect to the server through a default connection setup embedded in the first terminal identifier. By acquiring terminal identifiers corresponding to interacting mobile terminals, the first mobile terminal may establish communication channels with the interacting mobile terminals. After adding the terminal identifiers of the interacting mobile terminals to the contact lists of the first mobile terminal, different regions of the first mobile terminal may be designated to the interacting mobile terminals so that the regions may display the status of communication and serve as interfaces to control receiving, playing, recording, and transmitting digital contents encoding voice messages.
