A communication architecture to access data services through GSM
نویسندگان
چکیده
In this paper we present a communication architecture for accessing TCP/IP networks (mainly Internet) through GSM. We exploit the existing and widely used TCP/IP communication architecture, but also consider the specific features of wireless links and GSM networks. Our proposal is based in the indirect model of client/server interaction, where an intermediate element acts as a bridge between GSM and the rest of the data network. This intermediary provides enhanced functionality, improving the performance of standard TCP/IP applications in a mobile environment, maintaining the protocols in server machines, and requiring mimimum changes in the mobile clients. Those changes are basically the installation of a simple transport protocol. GSM operators are not required to change their network infrastructure in order to implement the architecture, even in the case of networks offering the new high-speed services for data transmission in GSM (GPRS and HSCSD).

This chapter presents a broad study on the potential of applying RRM techniques to the global system for mobile communication (GSM)/enhanced data rates for GSM evolution (EDGE) system. Even though the presented results are focused on the GSM/EDGE system, the principles employed by most of the considered RRM techniques can be applied to other radio access networks (RANs). We thus hope that the r...
