MEC (Multi-Access Edge Computing)

Multi-Access Edge Computing is the ETSI-standardised architecture that places computing resources at the edge of mobile networks, typically co-located with the UPF or aggregation sites, to reduce latency for applications such as AR/VR, industrial automation, and connected vehicles. MEC deployment expands the trust boundary of the mobile network and requires careful workload isolation and key management.

MEC in context

The mobile core is where subscriber sessions, mobility and policy live. In 4G it is the EPC (MME, HSS, S/PGW); in 5G it is the Service-Based Architecture with AMF, SMF, UPF, AUSF, UDM and the NRF. Core exposure is the difference between a single-subscriber leak and a fleet-wide breach.

Telecom security is written into standards from 3GPP, GSMA, ETSI, IETF and ITU-T. Understanding which body owns which specification, and how the specs interlock (for example 3GPP TS 33.501 with GSMA FS.34 for 5G SBA security), is essential for both design and audit work.

To place MEC in the wider telecom-security picture, review ETSI ISG MEC, Network Slice, AES, Zigbee, MEC Security and 5G.
