Radio Access Network Slice Construction via Master Base Station Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional communication networks with a simple architecture struggle to meet the diverse and demanding requirements of 5G mobile communication scenarios, such as ultra-high data transmission rates and low latency, due to limited infrastructure and spectrum resource utilization, and constructing dedicated networks for each scenario leads to resource waste.
Innovation Solution
The method involves constructing radio access network slices end-to-end between a master base station and neighboring secondary base stations, with the master base station transmitting network slice reconstruction configuration information to enable multi-connection data transmission, allowing for dynamic resource allocation and efficient use of radio, baseband processing, and network transmission resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dedicated network is constructed for each scenario to meet customized application and performance requirements, then the application and performance requirements are satisfied, but waste of infrastructure and spectrum resources occurs
Solution Approach 1:
The patent segments the physical network into multiple virtual network slices, where each slice is dedicated to specific application scenarios with customized requirements. This allows different virtual networks to coexist on shared physical infrastructure, satisfying diverse performance requirements while avoiding resource waste through consolidation
Solution Approach 2:
The patent creates a universal physical network infrastructure that can serve multiple different application scenarios simultaneously through virtualization. The same physical network resources can be dynamically allocated to different virtual slices based on demand, making the infrastructure multi-functional and adaptable to various customized requirements
2Loss of energy
If network function virtualization is implemented to build different virtual networks for different traffic requirements, then resource utilization is improved, but system complexity increases
Solution Approach 1:
The patent introduces network slice management functions as intermediary components that coordinate between the physical network infrastructure and multiple virtual network slices. These management functions handle resource allocation, slice configuration, and coordination tasks, simplifying the overall system architecture while enabling efficient resource utilization across multiple virtual networks

AI summary
Provided is a radio access network slice construction method and apparatus applied to a master base station. The method includes: constructing, by each of the master base station and at least one neighboring secondary base station in the RAN, a network slice end-to-end correspondence with a core network, and determining RAN slices information in the master base station and the neighboring secondary base station; collecting statistics, by the master base station, on Slice IDs or MDD information reported by all UEs served by the master base station, and obtaining quantity of slice resources needed to be allocated to construct RAN slices by the master base station; transmitting, by the master base station, reconstruction request information of a RAN slice to the neighboring secondary base station; and performing, by the master base station, multi-connection data transmission reconfiguration on the UEs served by the master base station through an RRC message.
