Tokyo, June 25, 2021―KDDI led the GSMA [Jump to the applicable section1] taskforce working on documentation of a whitepaper aiming at realization of End-to-End (E2E) [Jump to the applicable section2] Network Slicing, as an editor, in collaboration with major telecom operators and equipment vendors. The whitepaper became publicly available on June 3rd, 2021, on Open link in a new windowthe GSMA website.

This whitepaper describes the vision of E2E Network Slicing, the technologies to be utilized, and the status of related standardization work in each organization. It is expected that this whitepaper will accelerate the realization of E2E network slicing by facilitating sharing of issues and consensus formation on what need to be studied among many relevant companies.

In conventional network deployments, it is necessary to build individual physical networks according to the requirements of the services, and it is difficult to build a tailored physical network for each 5G service such as XR and IoT, which has a wide range of service quality to be required.
E2E network slicing is a technology that divides the physical network into multiple virtualized networks in a 5G standalone network (5G SA) [Jump to the applicable section3] and tailors each of them according to service requirements. It enables the provision of tailored network capabilities for each purpose of use, such as factory automation in the manufacturing industry, or autonomous driving, which leads to services that require low latency and high reliability.
On the other hand, as E2E network slicing is a technology spanning over multiple mobile network components, including core networks and base stations, it is a challenge for multiple standardization organizations and industry groups to study it in an integrated manner, and the whitepaper addresses this challenge. KDDI has been working on E2E network slicing [Jump to the applicable section4], and will continue to promote technology demonstrations, including standardization, through this white paper.
