Issues toward Networks Architecture Security for LTE and LTE-A Networks

With all these years’ rapid development in wireless communication, high demands for broadband mobile wireless communications and the emergence of new wireless multimedia applications have constituted the motivation to the development of broadband wireless access technologies. The Long Term Evolution (LTE) system has been specified by the Third Generation Partnership Project (3GPP) on the way towards fourth-generation (4G) mobile to ensure 3GPP keeping the dominance of the cellular communication technologies. In this paper, several security issues of the LTE and LTE-A networks have been discussed. First, we illustrate an overview of the LTE Network Architecture. Second, LTE security architecture is shown as well. Third, some drawbacks in LTE security framework are discussed in Section 4. Finally, some open issues will be talked, and hopefully this will be a guideline for the new learners.
