Abstract: A service terminal, which is communicatively coupled to a remote server, communicates with an offline mobile phone located nearby via a short-range wireless communication protocol to complete a service request initiated by the mobile phone. The service terminal repeatedly broadcasts, via a short-range wireless transceiver, a service message to neighboring mobile terminals until after receiving a service purchase request message from one of the mobile terminals. The service terminal then suspends the broadcast of the service message and submits the service purchase request to the remote server and then receives a purchase confirmation message from the remote server. Next, the service terminal transmits, via the short-range wireless transceiver, the purchase confirmation message back to the user terminal.

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.
