            6.1     Standardization activities for network softwarization

            6.1.1   Standardization activities at 3GPP SA2
            The “Study on Architecture for Next Generation System” (Rel-14) was started at SA2 #112 meeting and
            officially approved as 3GPP TR 23.799 at the 3GPP TSG SA #70 plenary in December 2015. The latest version
            (i.e. v1.2.0 November 2016) of the NextGen TR 23.799 can be found on the following links for more detailed
            information.
