RESTful Interfaces for Application Initiated D2D Communications

Abstract

Device-to-Device (D2D) communications feature ultra low latency and efficient resource utilization. D2D communications may be empowered by Multi-access Edge Computing (MEC) which brings cloud capabilities for storage and processing into radio access network. In this paper, we present an approach to define RESTful interfaces for open access to proximity-based service, which may be used by mobile edge applications to initiate device proximity discovery and direct communications. The approach is illustrated by typical use cases, data model, interface definition and proximity-based service state models, which are formally described and verified.
