Abstract

GSM (Global System for Mobile communication) is a digital mobile network technology utilized globally to communicate with the mobile devices. GSM digitizes and compresses data, then sends it down a channel with two other streams of user data, each in its own time slot assigned using the Time Division Multiple Access (TDMA). Cellular communication is a form of communication technology that enables the use of mobile phones. The proposed method allows the devices to connect by applying the network reconfiguration which enabling nearby user equipment to directly communicate with each other bypassing the cellular base stations. Mobile to Mobile (M2M) communication is the key technologies that can help to solve the problems occur in cellular networks. M2M communication enables users to connect to nearest devices and interact with each other even during absence of a mobile network. The common element of all generations of cellular communication technologies is the use of defined radiofrequencies (RF), as well as frequency reuse. It enables the creation of wide communication networks by fully integrating the advanced capabilities of the mobile phone. Direct communications between devices can provide several benefits to users in various applications where the devices are in close proximity. And also enables the user to make the call and messaging system without network services and internet. This could allow large volumes of media or other data to be transferred from one device to another over short distances and using a direct connection. This form of device-to-device transfer would enable the data to be transferred without the need to run it via the cellular network itself, thereby avoiding problems with overloading the network.
