Terminal application middleware for the interoperability among telematics services

摘要

Telematics offers automobile drivers with various and useful information services from telematics service provider (TSP) centers through a terminal in vehicle which is installing wireless communication devices such as CDMA, GSM, DSRC, etc. However, a vehicle environment, which telematics service is used, has poor surroundings in the large temperature variation and noise. Because of these conditions, Telematics terminals were developed with relative importance in stability itself more than the interoperability for the internal software circumstances. Therefore, software in the terminals has a lot of dependencies on its hardware conditions and the interoperability among contents can not be guaranteed any more. This paper introduces an application middleware for telematics terminals which was developed as a kind of telematics technology development project. The middleware based on open standard of JAVA technology can make operation among contents over itself. Because of providing standard interfaces of the middleware, it can make an easy to develop telematics services.
