Abstract

En 中文

Device-to-device (D2D) communications are based on direct signaling and data transmission within wireless devices. Furthermore, it facilitates mission-critical services for public safety (PS), vehicle-to-vehicle (V2V) or drones. These D2D applications need nationwide coverage across multiple operators. The existing roaming system, however, does not provide sufficient trust for D2D roaming scenarios since the direct link between devices is difficult to monitor in the core network side. Therefore, a novel framework to support D2D roaming is proposed inspired by blockchain-based trust systems. The framework consists of an authentication for D2D user equipment (UE) access, authorization to configure D2D service, and resource pool selection. Also, a dynamic D2D resource pool selection enabled by D2D class awareness is supported. Analytical results show that the proposed dynamic resource pool selection scheme improves capacity in the form of decoding performance.
