1. (WO1997017813) IMPROVED MESSAGE PROCESSING IN TWO-WAY DATA DEVICES
Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

What Is Claimed Is:
1. An improved method for processing messages in two-way data devices, said method comprising the following steps:
(a) receiving a new message, said new message divided into portions comprising first header information, a first signature and first response flag;
(b) determining whether there exists a matching message, said matching message being a previously received message comprising second header information that matches said first header information of said new message, said matching message further divided into portions comprising a second signature and second response flag;
(c) storing said new message when no matching message exists in step (b);
(d) determining whether said first signature of said new message is the same as the second signature of said matching message;
(e) performing an error check on said new message when said first and said second signatures are the same;
(f) comparing said first and second response flags when said first and second signatures are not the same in step (d), and when said first and second response flags are both enabled storing said new message, otherwise performing an error check on said new message;
(g) storing select portions of the new message and matching message in place of said matching message depending on the status of said first and second response flags and said error check performed in step (e) or step (f)-

2. An improved two way data device comprising a receiver section, a transmitter section and a microprocessor, said receiver section receiving messages divided into portions comprising header information, a first signature and response flags, said microprocessor performing the following steps in processing messages:
(a) determining whether there exists a matching message, said matching message being a previously received message comprising second header information that matches said first header information of said new message, said matching message further divided into portions comprising a second signature and second response flags;
(b) storing said new message when no matching message exists in step (a);
(c) determining whether said first signature of said new message is the same as the second signature of said matching message;
(d) performing an error check on said new message when said first and said second signatures are the same;
(e) comparing said first and second response flags when said first and second signatures are not the same in step (c) and when said first and second response flags are both enabled storing said new message otherwise performing an error check on said new message;
(f) storing select portions of the new message and matching message in place of said matching message depending on the status of said first and second response flags and said error check performed in step (d) or step (e).
