A Novel Model for Efficient Communication in 2g/2.5g or 3g Through Reduced Signalling Overhead
With its great features like providing access to users at anytime and anywhere in the world, mobile communication has been very attractive among the users as well as operators and service providers. However, despite of several advantages, mobile communication has also been facing many safety problems. In 2G/2.5G (GSM and GPRS) and 3G (UMTS) technologies, the architectures comprise of mainly three nodes; the Mobile Station (MS), Visitor Location Register/Serving GPRS Support Node (VLR/SGSN), and Home Location Register (HLR). These nodes are involved to encode/decode the data and validate the Mobile User (MU) in 2G and 3G.
