Lightweight protocol for use in a TCP/IP communications network
Abstract:
A lightweight communications protocol optimized for wireless transfer of data across a TCP/IP network that connects a vehicle communications device to a remote entity, such as a call center. The lightweight protocol utilizes messages that include header, trailer, and payload elements, where the payload element is optimized for the transmission of SOAP content as a default content type, but is capable of transmitting other types of non-SOAP MIME content as well. The lightweight protocol also reduces session overhead and thus data traffic by maintaining sessions in an open status so that numerous messages can be transferred within a single session, without having to shut the session down and rebuild it each time.
