Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple base stations with different air interface structures are deployed to support diverse 5G scenes, then the adaptability to different application scenarios is improved, but the device complexity and resource wastage increase
Solution Approach 1:
The patent implements a universal base station architecture where a single base station can support multiple air interface structures (E-UTRA, NR, etc.) and multiple scenes through the concept of Virtual Cells. The base station includes a processing unit that can handle different air interface protocols simultaneously, and a broadcasting unit that transmits system information for multiple Virtual Cells, enabling one base station to perform multiple functions that previously required separate base stations for each scene and air interface type.
2Adaptability or versatility
If multiple base stations are deployed to cover different scenes, then the scene coverage capability is improved, but the loss of energy and operational costs increase
Solution Approach 1:
The patent merges multiple Virtual Cells with different air interface structures into a single base station infrastructure. The base station includes a processing unit that consolidates the control functions for multiple air interfaces and a broadcasting unit that efficiently transmits system information for all Virtual Cells. This merging reduces the total number of base station units required, thereby reducing operational energy consumption and maintenance costs while maintaining comprehensive scene coverage.
3Device complexity
If a single air interface structure is used in the base station, then the device complexity is reduced, but the adaptability to different 5G scenes deteriorates
Solution Approach 1:
The patent segments the base station functionality into distinct Virtual Cells, where each Virtual Cell is configured with specific air interface structure parameters (e.g., E-UTRA, NR) and scene-specific system information. The processing unit maintains separate configuration data for each Virtual Cell, allowing independent air interface structures to coexist within a single base station without increasing overall device complexity, while enabling support for multiple 5G scenes through the segmented Virtual Cell architecture.

AI summary
The invention provides a base station supporting distributed multiple scenes, creation and communication method thereof and storage medium. The communication method includes: a second communication node broadcasts first information, wherein the first information is at least used for notifying a terminal of a scene type of the second communication node and information required for the terminal to access the second communication node; the second communication node receives and detects access information transmitted by the terminal, and determines a scene type of the terminal according to the access information; in response to determining that the scene type of the terminal is identical to the scene type of the second communication node and that a third communication node does not need to be established, the second communication node transmits data transmitted by the terminal to a core network via a first communication node on an upper layer of the second communication node; otherwise, the second communication node notifies the third communication node under the second communication node to establish a user equipment (UE) instance corresponding to the scene type of the terminal, until a data radio bearer (DRB) signaling interaction between the UE instance and the terminal is completed.
