Design and Test of Open Telematics Bundle Services under Heterogeneous Wireless Communications

This paper will propose a design and test records for a bundle service under heterogeneous wireless communicational environment for Telematics. The paper developed an open telematics system based on the open gateway and framework, which is interoperable with other telematics systems such as GPRS (2.5G), HSPA(3.5G), and WiMAX(3.5G). There are ten major services to compare with each other. The authors followed an extended global Telematics protocol (GTP) for mobile office service which can provide a lot of bundle services together for subscribed members.
