The patent application discusses technologies for managing control plane operations within a split architecture that divides functions between a centralized unit (CU) and a distributed unit (DU). This architecture is relevant to communication networks, particularly those defined by the Third Generation Partnership Project (3GPP) Technical Specifications, which set standards for wireless networks. The application aims to enhance the efficiency and functionality of signaling traffic in these networks.
This technology pertains to communication networks, focusing on the control plane within a CU-DU split architecture. The split allows for distinct handling of higher-layer and lower-layer protocols, optimizing network performance. The CU typically manages higher-layer protocols such as radio resource control and packet data convergence, while the DU manages lower-layer protocols like radio link control and media access control.
The application builds on existing standards from the 3GPP, which outline the structure and function of wireless networks. These standards are crucial for ensuring consistent and reliable communication across different network systems. The invention seeks to address challenges in these systems by refining how signaling traffic is managed, particularly in newer generations of wireless technology like 5G and beyond.
The detailed description provides insights into the specific components and methods used in the CU-DU architecture. It explains how the CU and DU divide responsibilities for protocol management, which can enhance network efficiency. The description also includes a glossary of terms to clarify the technical language used, ensuring a comprehensive understanding of the technology's scope and application.
The network environment described includes user equipment connected to a base station within a radio access network. This setup is compatible with 3GPP standards and supports advanced systems like 5G and potentially 6G. The base station's split architecture, comprising a CU and one or more DUs, facilitates improved handling of both user and control plane protocols, thereby enhancing overall network performance.
