Unified Message Applied Language Studies

With the development of communication technology, people have to be confronted with many kinds of devices to communicate with each other such as mobile telephone, BP, Fax etc. Too many devices make it difficult to obtain messages. How to integrate these communication ways so that we can get messages easily? Unified Messaging Service (UMS) can solve this problem; it provides a single point of access to multiple message types including voicemail, fax, and e-mail etc. These messages can be sent in a number of formats ?including most popular SMS and instant message (IM) formats. By implementing unified messaging, users can take back control of their communications. UMS allows users to access voice, fax, and email from anywhere, using any device, at any time.The key of UMS is how to neutralize the differences arising from the variety of information and implement the conversion of different formats. As the pace of business increases, the short message service is increasing rapidly. Short message service has become an attracting business for mobile network. This paper will mainly discuss the conversion between short message and other kinds of information.According to the current implementation of short message service, the Service Provider (SP) exchanges messages with short message gateway (SMG) by CMPP or SGIP interface, therefore the SP should be familiar with these protocols. Most protocols that support the message transfer between the SMSC and external short message entity (ESME) are binary protocols over an underlying TCP/IP or X.25 network connection. Since binary protocol is not readable, for SP it is hard to implement these interfaces. This paper defines a new text based protocol language that is called GSML and provides the interface for it. Messages from ESME can be sent to UM platform with structured text complying with the language, then the UM converts the text content to binary data and sends to SMG. Using this new protocol language, an ESME need not to be familiar with binary protocols such as CMPP or SGIP.Chapter 1 describes the background and need of UMS and GSML. Chapter 2 provides a description of the structure and application of UMS. Chapter 3 illustrates the development and the related technologies of SMS, such as SMPP, CMPP and SGIP etc. Chapter 4 provides the design of General Short Message Language (GSML). Chapter 5 details the implementation of the interface for GSML, including the parser of GSML, the definition of related class and the pack of data. Finally, Chapter 6 concludes the trends of UMS and SMS application.
