摘要

A system for obtaining information is disclosed. The system comprises a server, a sender and a receiver and a communication means for the server to communicate with the sender and receiver. The receiver initiates a request message which is transmitted to the server. In the event the server is unable to immediately reply to the request with information for the receiver, the server retains the request in a pending state. The server retains the request in a pending state until a time when the server is able to respond to the request with information for the receiver and wherein at such time, the server allows for the completion of the receiver request with the information.
