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: A method and system for connecting a peripheral device to a user device via a Bluetooth protocol, comprising: at the peripheral device: initiating an broadcasting process, comprising: broadcasting a device discovery message, the device discovery message comprising a predetermined identifier designated for a social networking service associated with a social networking application executing on the user device; receiving, from the user device, a connection request corresponding to the device discovery message; and in response to receiving the connection request from the user device, establishing a Bluetooth connection to the user device.

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.
