Abstract：The network slicing function is the required function of the future 5G cellular mobile network. How to realize and implement the end to end (E2E) network slicing function in 5G celullar next generation-radio access network (NG-RAN) is one of the hot topics in the past 3rd Generation Partnership Project (3GPP) standard and R&D activities. Based on various facts of 3GPP standardization process, the comprehensive views about its development are given and some essential technical issues behind with full considerations of Pros and Cons aspects are analyzed. It is considered that the 5G network has the capability of E2E network slicing, but there are still some technologies that need to be further developed and promoted.
