44、he following principles are important to understand in the context of Mobile Edge Computing. 4.2 NFV alignment Mobile Edge Computing uses a virtualisation platform for running applications at the mobile network edge. Network Functions Virtualisation (NFV) provides a virtualisation platform to networ
45、k functions. The infrastructure that hosts their respective applications or network functions is quite similar. In order to allow operators to benefit as much as possible from their investment, it would be beneficial to reuse the infrastructure and infrastructure management of NFV to the largest ext
46、ent possible, by hosting both VNFs (Virtual Network Functions) and mobile edge applications on the same or similar infrastructure. Subject to gap analysis, this might require a number of enhancements (e.g. regarding the sharing of resources with NFV Management and Orchestration, etc.). 4.3 Mobility
47、support Mobility is an essential functionality of 3GPP networks. Most devices connected to a 3GPP network are moving around within the mobile network. Even fixed devices can “move“, especially when located at cell edge, but also when changing RATs, etc., or during exceptional events (e.g. power cut
48、from a base station, etc.). Some mobile edge applications are state-independent and do not need to keep state information related to the UEs they are serving. For example, an application in the category “network performance and QoE improvements“ will only improve the performance of the UE traffic wh
49、en the traffic goes through that mobile edge host. When the UE moves to a different location covered by another mobile edge host, it will be the application hosted on that mobile edge host that will take care of the UE after a brief transition period. Past interaction is not useful for the application. Other mobile edge applications, notably in the category “consumer-oriented services“, are specifically related to the user activity. Either the whole application is specific to t
