Abstract:
1. A WAP (Wireless Application Protocol) analyzer located on a transmission line between communication apparatuses using WAP, a WAP packet includes at least one WTP-PDUs (Wireless Transaction Protocol-Protocol Data Unit), said WAP analyzer comprising: database for storing state-transition specification data that define a state-transition with a cause-and-effect relationship between WTP-PDUs, states of a WTP layer, primitives between said WTP layer and WSP (Wireless Session Protocol) layer, and states of said WSP layer, based on WAP specification; means for extracting said WTP-PDUs from said WAP packets; and means for estimating said state-transition of said WTP layer and said WSP layer, to said apparatus that received one of said WTP-PDUs and subsequently sent other of said WTP-PDUs, for each pair of a sender and a receiver; and means for displaying said state-transition.
