Abstract
the extensive proliferation of mobile applications and smartphones, there is an increasing trend of technical adoption of 3G (third generation). But, with the exponential growing of massive traffic, it is seen that even 3G network is completely not capable of catering to the dynamic needs of the customers. This paper focuses on the usage of 4G-LTE (fourth generation-long term evolution) network that has higher support for heterogeneous network access catering to the needs. 4G-LTE is designed on the principles of packet switching system on the backbone of IP protocol. This paper presents a review on the state-of-art techniques from the viewpoint of mobility management approach, which is highly enriched with informative contents compared to existing reviews.
