ogy and most of the use cases appear to focus on the connected cars. With the next-generation system, the latency requirements are set to less than 1 ms to empower a wide range of use cases. MEC is the ideal solution and has been identified as a key component to support these ultra-low latency scenarios as it enables hosting applications close to the users at the edge cloud and therefore provides the shortest path between the applications and the servers. Computationally intensive applications running on mobile terminals may be offloaded to the cloud for various reasons, such as availability of more computing power or of specific hardware capabilities, reliability, joint use of the resources in collaborative applications, or saving network capacity. The computation offload is particularly suitable for IoT applica- tions and scenarios where terminals have limited computing capabilities, to guarantee longer battery life. Such offload may happen statically (server components are deployed by the ser- vice provider proactively in advance) or dynamically (server components are deployed on demand by request from the UE). In this case, applications benefit from the low delay pro- vided by the MEC. 1.1.7.2 Architectural Aspects MEC provides a highly distributed computing environment that can be used to deploy appli- cations and services as well as to store and process content in close proximity of the mobile users. Applications can also be exposed to real-time radio and network information and can offer a personalized and contextualized experience to the mobile subscriber. This translates into a mobile broadband experience that is not only more responsive but also opens up new business opportunities and creates an ecosystem where new services can be developed in and around the base station. Fig. 1.46 shows the high-level functional entities in the MEC framework, which are further grouped into the system-level, host-level, and network-level entities. The host-level group consists of the MEC host and the corresponding MEC h
