Synchronizable Short Message Browser based on XML

Problem Solved

This invention provides a new architecture and a new programming model to enable SMS browsing user experiences, enhance SMS synchronization capability with other browsing channels and ease the difficulty in developing SMS based interactive services.


Invent SMS browser with a new SMS Gateway to separate SMS applications from vendor specific details. Propose SMS XML to describe SMS service applications and define a DOM based SMS Browser to interpret this description markups, and to map between this markups with other popular markup languages (WML, HTML) so as to support multimodal browser architecture which enable the synchronization between Voice application and SMS application. A SMS transcoding mechanism is also included. Define a new architecture and programming model to enable interactive, session based SMS service application development and delivery

2. How does the invention solve the problem or achieve an advantage,(a description of "the invention", including figures inline as appropriate)?

Background :

SMS (Short Message Service) is a relatively simple messaging system provided by the mobile phone networks. As a universal mobile data service, SMS messages are supported by GSM, TDMA and CDMA based mobile phone networks currently in use. Services based on SMS have been feasible for many years, the recent mobile phone penetration and large scale user adoption of the existing services have made the SMS-based services even more attractive to service providers. Although other services enabled by WAP (Wireless Application Protocol) and UMTS (Universal Mobile Telecommunications System) will most propably replace SMS messages as the most popular media for wireless aplications, there will still be a very large user base still for a long time. The great market interest related to mCommerce (mobile commerce) has also made SMS more interesting as a service delivery channel. Operators and service providers want to create many new services based on it.

However, there are also some limitations and difficulties in developing SMS based services.

First of all, current SMS has no interactive capability, it is not session based, but just a store and forward way of transmitting messages to and from mobiles. Thus it can not support complicate application logic. There isn't a well defined programming model for SMS that can separate application logic from interaction code. SMS based solution tends to rely on vendor specific phone set or SMS center protocol. There isn't a clear cut application programming model that separates application logic from these vendor specific details; Application programmer has to take care of the performance and scalability issues; These make SMS based solution proprietary and expensive.
