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.
