ces, into the network edge, e.g., BS or eNB/gNB [64, 199]. It has been standardized by ETSI ISG and European 5G infrastructure public-private partnership. In this context, ETSI ISG in [200] proposed several white papers for MEC principles and frameworks including several UCs, APIs requirements, implementation and tests, and architectural frameworks. In the early versions of MEC standardization by ETSI, MEC has been denoted as mobile edge computing which has been defined, later, as multi-access edge computing. 1.4.5.1 MEC Architecture MEC architectural framework has been explored, in the literature, by several standards, research works, and books. Table 1.9 presents standards and research works that investigated the implementation of MEC within the 5G eco-system. The M. Alfaqawi et al.
