Design Of The Gateway Between Instant Message And Digital Trunking Short Message

Short message business is one of the basic businesses of mobile communication.In IMS network based on IP,short Message has transformed into a new form,called Instant message.Unlike the traditional short message,it is attached to the chat software terminal.SDS(Short Data Service)is a short message business in the digital trunking system,similar to the short message business of the mobile communication system.It is characterized by dedicated network,and its signaling and process are different from those of other communication systems.Making Instant message and SDS interconnection can expand more business,letting independent dedicated network share business,and then building a resource sharing,to coordinate the operation of the communication network platform.This is a meaningful thing.The work of this paper is to study and achieve this goal.This paper is divided into 6 chapters.Chapter 1 introduces the background of the paper.Chapter 2 introduces IMS system,digital trunking system,network communication development trend.Chapter 3 analyzes the business requirements.Chapter 4 introduces the design plan.Chapter 5 describes the testing process of the gateway.Chapter 6 summarizes the research process.
