This aspect (coupled with the network virtualization) makes MEC adoption particularly well suited to support next-generation services requiring very low latencies and/or high bandwidth, such as vehicular ones (from in-vehicle infotainment to assisted/cooperative driving). In addition, operators can exploit their hosting facilities at the edge of mobile networks and can open their radio access network (RAN) edge to authorized third parties, allowing them to flexibly and rapidly deploy innovative applications and services towards mobile subscribers, enterprises, and vertical segments. More specifically, when implementing MEC in mobile networks, MEC hosts are placed at the edge of the network (e.g., close to the radio access network of a 4G or 5G cellular network) and support MEC applications, leveraging edge services exposed through APIs, e.g., radio network information (RNI) API or location API, helping to tailor their computation based on the network conditions or user location. Other APIs can be exposed to MEC applications following the general design principles of RESTful APIs, to ensure interoperability and portability of MEC applications across different domains.
