ABSTRACT:
A system for sending and responding to information requests in a wireless communications network includes a display device, a central processing unit, memory means including random access memory and read-only memory, an input device, and a transmitter/receiver. The random access memory further comprises routines for processing, sending and receiving messages over the wireless network.
The present invention also comprises a method for requesting information and a method for responding to requests for information. The preferred method for handling information requests comprises the steps of: monitoring the communications channel for availability; sending an information request over the channel; receiving the information request at each node within the network; preparing responses to the information request at each node; and sending the response to the information request over the channel if it is available. The method for responding to a request for information advantageously uses the minimum number of request to solicit the minimum number of replies to the information request.
