Base Station RRC Connection Management via Bearer Priority Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radio resource control (RRC) connections in cellular networks face congestion issues due to limitations on the number of connections permitted by base stations, which existing protocols fail to effectively manage, especially when prioritizing bearer connections.
Innovation Solution
Implementing a method where base stations analyze radio bearer attributes to determine whether to establish, maintain, or terminate RRC connections based on priority levels, allowing for intelligent management of network congestion while honoring priority levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If base stations permit multiple RRC connections to handle network traffic, then network capacity and service coverage are improved, but network congestion occurs when the connection limit is reached
Solution Approach 1:
The patent applies local quality by differentiating treatment of RRC connections based on their associated radio bearers' priority levels. High-priority bearers receive preferential treatment in connection management, while low-priority bearers are subjected to stricter control during congestion. This allows the base station to manage connections heterogeneously rather than uniformly, resolving the contradiction by quality differentiation.
Solution Approach 2:
The patent changes the parameter of connection priority by associating RRC connections with priority levels derived from radio bearer attributes. The base station dynamically adjusts connection management decisions based on these priority parameters, allowing flexible control over connection admission and termination to prevent congestion while maintaining necessary services.
2Productivity
If base stations terminate low-priority RRC connections during congestion, then network congestion is relieved, but service quality for critical communications may be affected
Solution Approach 1:
The patent ensures service reliability by protecting high-priority RRC connections from termination during congestion. The base station identifies connections associated with high-priority radio bearers and maintains them even under congestion conditions, while only terminating low-priority connections. This selective approach relieves congestion without affecting critical communications.
Solution Approach 2:
The patent implements feedback mechanisms where the base station continuously monitors network congestion status and radio bearer priority levels, dynamically adjusting connection management decisions. When congestion is detected, the system feedback-drivenly terminates appropriate low-priority connections while preserving high-priority ones, thus maintaining service reliability while improving overall network productivity.
3Ease of operation
If existing protocols manage RRC connections without prioritization, then connection establishment is simple, but intelligent management of network congestion is not achieved
Solution Approach 1:
The patent extends the RRC connection management function to include priority-based differentiation while maintaining compatibility with existing protocols. The base station uses radio bearer attributes to derive priority levels and applies these to connection management decisions, making the system adaptable to different service requirements without requiring entirely new protocols.
Solution Approach 2:
The patent performs preliminary action by pre-establishing priority associations between radio bearers and RRC connections based on bearer attributes. This allows the base station to make rapid congestion management decisions without complex real-time analysis, maintaining operational simplicity while enabling intelligent congestion management through pre-configured priority information.

AI summary
A base station may establish a radio resource control (RRC) connection with a first user device. The base station may determine a bearer attribute of a bearer associated with the RRC connection and the first user device. The base station may determine that the bearer attribute satisfies a set of conditions, and may analyze multiple bearer attributes associated with multiple established RRC connections. The base station may select a terminable RRC connection, of the multiple established RRC connections, based on analyzing the multiple bearer attributes. The terminable RRC connection may be associated with a second user device that is different from the first user device, and the terminable RRC connection may be different from the RRC connection. The device may terminate the terminable RRC connection based on selecting the terminable RRC connection.
