ITU-T Recommendations

The IMT-2020 network will enable a variety of services, including enhanced mobile broadband (eMBB) services, massive machine type communications (mMTC) based services and ultra-reliable low latency communications (URLLC) based services, on an infrastructure of network and computing resources. In line with the key features and the requirements identified for the IMT-2020 network, it is required to be more efficient, personalized, intelligent, reliable and flexible.
To support the typical services in the IMT-2020 network, especially eMBB services and URLLC based services, edge computing is acknowledged to be one of the key technologies for meeting the demanding key performance indicators (KPIs) of the IMT-2020 network, especially as far as low latency and bandwidth efficiency are concerned.
Edge computing enables the operator and the third party service provider to deploy the services close to the user's access point, thus achieving high-efficiency service delivery through reduced end-to-end latency and load on the transport network.
In order to ensure the security of edge computing service deployment and application, the security threats and relevant security requirements specific to edge computing service need to be analysed and the overall security framework need to be established.
This draft Recommendation aims to analyses the deployment scheme and typical application scenarios of edge computing services, specifies the security threats and requirements specific to edge computing services in IMT-2020 and thus establishes security capabilities for the operator to safeguard its applications.
