Without this basic function, features such as hand-over between cells would not work. Since mobile devices are typically associated with a single person, this provides a potential mechanism for user location surveillance. Network operators are bound by strict privacy legislation. However, spying by certain agencies, hackers and even advertisers without the users’ or operators’ knowledge has become a serious issue. In this article, we introduce and explain all known recent attacks on mobile networks that compromised user privacy. We focus on attacks using the Signalling System 7 (SS7) protocol as the interconnection interface between operators mainly in GSM networks.

  • 2. an Optimized Cellular Network Design Using Various Technologies
    International Journal of Engineering Research and General Science Volume 3, Issue 2, March-April, 2015 ISSN 2091-2730 An optimized cellular network design using various technologies within a service area N. Anish 1, A. Neelima 2, G. Deepti 2 Student, M.Sc., Telecommunication Engineering, Staffordshire University, Staffordshire, United Kingdom1 Student, M. Tech, Dept. of ECE, Bapatla Engineering College, Bapatla, India2 Abstract— this paper deals with Optimized Cellular Network with different access technologies with in the Staffordshire country. The main aim is to provide good coverage to the customers in the prescribed area as per the customers‟ utilization. For the cause of poor coverage probability and higher call blocking rates the network has been redefined. So the cellular network was designed with the target coverage probability of 0.98 and blocking probability of 1% which covers entire Staffordshire country. For designing practically we use a tool called ''MENTUM PLANET'' software providing capacity, coverage and frequency planning and analysis of Staffordshire County according to the customers‟ utilization. Keywords— Global Systems for Mobile Communications, Universal Mobile Telecommunications Systems, Long Term Evolution, Core Network, UMTS Terrestrial Radio Access Network, Radio Network Controller, Frequency Division duplex.. 1. INTRODUCTION In present day technology, mobile world plays a high flying role in every individual day to day life. There has been drastic change in the field of cellular technology since few decades. Even today the network technologies are developing with new requirements depending upon the usage of traffic, but in early days it was utilized for minimum and limited requirements. Here we are designing optimized cellular network and obtaining network constraints and parameters.
