In this part we focus on the EPC Architecture.
00:04 We started with why an upgrade of architecture was required.
00:48 Then we tried to explain the basic functionality of EPC with an Real life analogy.
02:28 After that we discussed about the various nodes of EPC and their primary functionalities.
04:09 We concluded the video by giving a summarized idea of how EPC carries out Authentication and Authorization of services and
04:33 finally showed the advantages of the all-flat IP Architecture of LTE.
