MEC technology enables applications

services and content to be localized and distributed deployed at close by migrating computing storage and service capabilities to network edges.Therefore

some of the5 G problems were solved to meet business requirement such as 5 G enhanced mobile broadband

low delay high reliability

and large scale machine communication terminal connection.In this paper

the key technologies of MEC in LTE network are analyzed combined with 3 GPP and operators research.Typical5 G MEC deployment scheme and the evolution of the MEC networking architecture are presented.
