s (APIs), are designed to serve a wide set of 5G use cases also encompassing automotive scenarios. The definition of such APIs represents a key activity within the MEC ISG. One of the first detailed services available on the MEC platform is the Radio Network Information Service, specified in ETSI MEC ISG-MEC 012, which provides up-to-date RAN information relating to UEs in the network. This might be useful while collecting channel state information of VUEs SO as to perform, e.g. user profiling operations or localization procedures. Future API refinements will provide V2X applications with predictions on the quality of service (QoS) performance of the V2I link: this is a fundamental feature for car OEMs not only to improve reliability but also to support dynamic and fast decisions in the next road segment, where vehicles may switch to a safe off-line mode if the QoS forecast is poor. In combination with such service, the MEC Location Service (ETSI MEC ISG-MEC 013) is a powerful tool enabling applications to exploit user proximity information, e.g. to retrieve and monitor the list of users connected to a particular cell or access point. This service appears essential for V2X applications to estimate the location of pedestrian/vehicles SO as to improve the overall safety. Additionally, the UE Identity Service (ETSI MEC ISG-MEC 014) allows applications to trigger user-specific traffic rules on the MEC platform by e.g. steering traffic to a local network. Finally, the Bandwidth Management Service (ETSI MEC ISG-MEC 015) enables applications to reserve networking resources to ensure specific 13.4 Cloudification in V2X Environments quality of experience (QoE) requirements. Currently, the ETSI MEC ISG is pursuing additional service APIs, one targeting specifically the V2X use cases, with the aim of facilitating V2X interoperability in a multi-vendor, multi-network, and multi-access environment. 13.4.3 MEC-Based Support for V2X Applications Given the variety of differentiated services, 5G (and beyond) network design will c
