Abstract

A method of wireless communication is provided. The method includes receiving a first request, generating a first compressed request and a first request dictionary based on the first request, and communicating the first compressed request and the first request dictionary via a wireless link toward an application operable to respond to the first request. The method further includes receiving a second request, generating a second compressed request and a second request dictionary based on the second request and the first request dictionary, and communicating the second compressed request and the second request dictionary toward the application via the wireless link.
