On March 26, 2020, the second working meeting of the 5G Network E2E Slicing Project Group of CCSA (China Communications Standards Association) was held online.

It was decided that the three sector standards 5G Network Slicing – General Technical Requirements for E2E Technology, 5G Network Slicing – Technical Requirements for E2E Slicing Connections Based on SPN Bearer Networks, and 5G Network Slicing – Technical Requirements for E2E Slicing Connections Based on IP Bearer Networks, need more discussion in order to submit the call for comments of these standards at the next working meeting. It is also suggested that more details should be incorporated in the draft for discussion of the sector standard 5G Network Slicing – Technical Requirements for SLA Guarantee.

Background:

From March to June 2020 is a critical time for the commercial use of 5G SA in China, and network slicing is one of the most dominant characteristics of 5G SA. In terms of standards, although 3GPP, IETF, ITU-T, ETSI and TCs of CCSA are carrying out standardization work on network slicing, the pace of cross-domain standardization lags behind that of the commercial use of 5G. In order to support the commercial use of 5G SA, it is necessary for China to develop relevant technical standards. As the leading standard of the standards series for 5G SA, 5G Network Slicing – General Technical Requirements for E2E Technology will specify the overall architecture of 5G network slicing E2E technology, basic functional requirements for 5G network slicing, functional requirements and interface connection of each subdomain (terminals, wireless network, transmission, core network, and management), , protocol and capability requirements for basic slicing security, and key business processes. It will provide guidance for other standards in the series and technical guidance for research, development and deployment of related equipment.
