Abstract
5G is becoming open, service-oriented, and software- oriented by introducing Service Based Architecture (SBA) into its core network. In consequence, we propose SBA-based mobile edge computing (MEC) in this paper. Firstly, we present a service-based MEC platform architecture, composed of network functions (NFs) and service based interface. We design several specific NFs that are different from SBA in 5G core network. Secondly, MEC platform architecture is enhanced by introducing templates for dedicated MEC services. Thirdly, we present a MEC orchestration scheme, which contains parameter configuration and instantiation. We establish a testbed based on an open source software, and experiment results demonstrate that our proposed SBA-based MEC can provide users with customized services, e.g., low latency computing and high speed caching.
