Method, user terminal, and service terminal for processing service data
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.
1. A computer-implemented method comprising:
at a service terminal having one or more processors and memory and a wireless signal transceiver, wherein the service terminal is communicatively coupled to a remote server:
repeatedly broadcasting a service message through the wireless signal transceiver, the service message including a service provider identifier and service-related information;
receiving a first service purchase request message wirelessly transmitted from a first user terminal adjacent the service terminal, the first service purchase request message including the service-related information and service-purchasing authorization information;
in response to receiving the first service purchase request message:
suspending the broadcast of the service message;
transmitting the service-purchasing authorization information and the service provider identifier to the remote server;
receiving a purchase confirmation message from the remote server; and
wirelessly transmitting the purchase confirmation message to the first user terminal;
after receiving the first service purchase request message:
receiving a second service purchase request message wirelessly transmitted from a second user terminal adjacent the service terminal; and
in response to receiving the second service purchase request message, returning a service purchase denial message to the second user terminal, wherein the second user terminal is configured to display the service purchase denial message on its screen.
2. The method of claim 1 , wherein the service provider identifier is a public account identifier of a social networking application and the service-purchasing authorization information includes an identifier of the first user terminal and a user account identifier of the social media application.
3. The method of claim 2 , wherein the service-purchasing authorization information further includes a purchase confirmation number and a current timestamp of the first user terminal.
4. The method of claim 1 , wherein the first user terminal is configured to acquire the service provider identifier by scanning a bar code before receiving the service message.
5. The method of claim 1 , wherein the wireless signal transceiver is configured to comply with a wireless communication protocol selected from the group consisting of Bluetooth, WiFi, and NFC.
6. The method of claim 1 , wherein the service-purchasing authorization information is partially encrypted by the first user terminal before its being transmitted to the service terminal and the remote server is configured to decrypt the partially-encrypted service-purchasing authorization information before generating the purchase confirmation message.
7. The method of claim 1 , further comprising:
after receiving the purchase confirmation message from the remote server:
determining whether the service was purchased successfully or not; and
resuming the broadcast of the service message in accordance with a determination that the service was not purchased successfully.
8. The method of claim 1 , further comprising:
in response to receiving the first service purchase request message:
returning a service purchase acknowledgment message to the first user terminal, wherein the first user terminal is configured to display the service purchase acknowledgment message on its screen.
9. A service terminal, comprising:
one or more processors;
memory; and
one or more programs stored in the memory and to be executed by the one or more processors, wherein the service terminal is communicatively coupled to a remote server, the one or more programs further including instructions for:
repeatedly broadcasting a service message through the wireless signal transceiver, the service message including a service provider identifier and service-related information;
receiving a first service purchase request message wirelessly transmitted from a first user terminal adjacent the service terminal, the first service purchase request message including the service-related information and service-purchasing authorization information;
in response to receiving the first service purchase request message:
suspending the broadcast of the service message;
transmitting the service-purchasing authorization information and the service provider identifier to the remote server;
receiving a purchase confirmation message from the remote server; and
wirelessly transmitting the purchase confirmation message to the first user terminal;
after receiving the first service purchase request message:
receiving a second service purchase request message wirelessly transmitted from a second user terminal adjacent the service terminal; and
in response to receiving the second service purchase request message, returning a service purchase denial message to the second user terminal, wherein the second user terminal is configured to display the service purchase denial message on its screen.
10. The service terminal of claim 9 , wherein the service-purchasing authorization information is partially encrypted by the first user terminal before its being transmitted to the service terminal and the remote server is configured to decrypt the partially-encrypted service-purchasing authorization information before generating the purchase confirmation message.
11. The service terminal of claim 9 , wherein the one or more programs further include instructions for:
after receiving the purchase confirmation message from the remote server:
determining whether the service was purchased successfully or not; and
resuming the broadcast of the service message in accordance with a determination that the service was not purchased successfully.
12. The service terminal of claim 9 , wherein the one or more programs further include instructions for:
in response to receiving the first service purchase request message:
returning a service purchase acknowledgment message to the first user terminal, wherein the first user terminal is configured to display the service purchase acknowledgment message on its screen.
