A distributed and adaptive data flow system for SMS

This paper describes a CMPP (china mobile peer to peer) Internet distributed and adaptive system for SMS (short messaging service). It is used to provide the information for the users of the cell phones by short messages. The system for SMS is often subject to rigid restrictions of delivery, and the data stream of the system is fairly asymmetrical. Sometimes the data stream flux received by us is high, whereas sometimes low. Therefore when the data stream is very large, the data often cannot be processed by the system for SMS in real time. In order to solve the problems mentioned above efficiently, after presenting the structure of this system for SMS, we mainly introduce you two new methods, including adaptive data flow algorithm and distributed client algorithm. Finally some terse conclusions are given. Just as the experiments prove, the implemented system for SMS has some advantages in the quality, performance and adaptability of the data stream.

I. INTRODUCTION

The Short Message Service (SMS)^[5] is able to send and receive text messages of up to 160 characters at a mobile phone. SMS is conceived as one part of the Global System for Mobile communications (GSM)^{[7], [8]} digital standard, originally only at 900MHz but later also at 1800MHz (also known as DCS1800), 1900MHz (also known as PCS1900) and 800MHz (E-GSM).^{[6], [7], [8]} Therefore we can use these facilities on any GSM or “Personal Communications Networks” (PCN which is also GSM) in principle.
