The non-IP D2D PDCP-encapsulated communication can further include two forms of secure data transfer. A first non-IP D2D PDCP-encapsulated communication can be a negotiated non-IP D2D PDCP-encapsulated communication. A second non-IP D2D PDCP-encapsulated communication can be a non-negotiated non-IP D2D communication. The non-negotiated non-IP D2D PDCP-encapsulated communication can include a common key management server (KMS) version and a distributed KMS version. The encapsulated communication can be used with various protocols, including a PC5 protocol (such as the PC5 Signaling Protocol) and wireless access in vehicular environments (WAVE) protocols."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems, methods and devices for direct communication","description":"Device to device (D2D) communication can be performed with packet data convergence protocol (PDCP) based encapsulation without internet protocol (IP) addressing.
