Base Station Function Entities for Multi-Cell Service Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current base station devices are limited to providing service for up to 256 cells and low-power access points like HeNBs can only serve one cell, failing to meet the increasing bandwidth requirements of user equipment in mobile broadband services.
Innovation Solution
A base station device is designed with multiple base station function entities, each capable of serving one or more cells, and utilizes global identifiers to create communication interfaces with network nodes, enabling the forwarding of data and supporting multi-cell service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a base station is configured with multiple cells (up to 256 cells), then the system capacity is enhanced, but the base station cannot provide service for more than 256 cells
Solution Approach 1:
The base station device is divided into multiple base station function entities, where each entity can independently manage and provide service for one or more cells. This segmentation allows the overall system to exceed the traditional 256-cell limitation by distributing cell management across multiple functional entities within a single base station device.
2Area of stationary object
If an HeNB is introduced to expand network coverage, then the macro network coverage is enhanced, but the HeNB can only provide service of one cell
Solution Approach 1:
The base station function entities are designed with universal capabilities to provide multi-cell services. Each function entity can serve multiple cells simultaneously, transforming the traditional single-cell HeNB into a multi-functional entity capable of handling multiple cells, thereby enhancing both coverage and service capability.
3Adaptability or versatility
If multiple base station function entities are introduced to provide multi-cell service, then the cell service capability is enhanced, but the device complexity increases
Solution Approach 1:
Multiple base station function entities are merged within a single base station device, sharing common hardware resources such as processors, memory, and communication interfaces. This merging approach enables multi-cell service capability while minimizing the increase in physical device complexity through resource virtualization and shared infrastructure.
