Dynamic Bearer Configuration for Relay Base Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, the bearer connection of a relay-WCD serving multiple relay base stations often becomes a bottleneck due to insufficient guaranteed minimum bit rate or quality of service attributes, leading to user-experience issues and service problems.
Innovation Solution
A method and system where a gateway or entity detects changes in the number of relay base stations served by a relay-WCD and dynamically modifies the configuration of the bearer, including the guaranteed minimum bit rate and quality of service level, to accommodate the increased or decreased traffic demands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a relay-WCD serves multiple relay base stations with a fixed bearer configuration, then the system structure is simple and easy to manage, but the guaranteed minimum bit rate becomes insufficient leading to service bottlenecks
Solution Approach 1:
The patent implements dynamic bearer configuration where the network controller automatically adjusts bearer parameters (QCI, guaranteed bit rate) based on the number of relay base stations served by a relay-WCD. The system transitions from static to dynamic configuration, detecting changes in relay base station quantity and modifying bearer attributes accordingly to maintain service quality without manual intervention.
Solution Approach 2:
The system establishes a feedback mechanism where the network controller continuously monitors the number of relay base stations served by each relay-WCD and uses this information to adjust bearer configurations. This closed-loop control ensures that service quality requirements are met by adapting bearer attributes in response to changing network conditions.
2Reliability
If the guaranteed minimum bit rate is increased to support multiple relay base stations, then service quality improves, but network resource consumption increases
Solution Approach 1:
The patent implements dynamic adjustment of guaranteed minimum bit rate based on the actual number of relay base stations served. When a relay-WCD serves more relay base stations, the system increases the guaranteed bit rate; when fewer relay base stations are served, the bit rate is reduced. This dynamic approach ensures service quality is maintained while avoiding unnecessary network resource consumption.
Solution Approach 2:
The system changes bearer parameters (QCI, guaranteed bit rate) based on the quantity of served relay base stations. The network controller detects changes in the number of relay base stations and modifies corresponding bearer attributes, allowing the system to adapt resource allocation to actual service demands rather than using fixed high allocations.
3Reliability
If manual configuration of bearer attributes is performed for each relay-WCD, then service quality can be optimized, but the operation and maintenance complexity increases
Solution Approach 1:
The patent enables the system to automatically configure and adjust bearer attributes without manual intervention. The network controller autonomously detects when a relay-WCD begins serving or stops serving relay base stations and automatically modifies the corresponding bearer configurations. This self-service mechanism eliminates the need for manual configuration management while maintaining optimized service quality.
Solution Approach 2:
The system uses automated feedback mechanisms where the network controller monitors network conditions and automatically adjusts bearer configurations in response to detected changes in relay base station serving patterns, replacing manual configuration processes with intelligent automated control.

AI summary
A gateway or other entity will detect when the number of relay base stations served by a relay-WCD changes and will responsively modify a configuration of a bearer that extends between the relay-WCD and the gateway. For instance, in response to detecting an increase in the number of relay base stations served by the relay-WCD, the entity could increase a guaranteed minimum bit rate and/or other quality of service level of the bearer. Or in response to detecting a decrease in the number of relay base stations served by the relay-WCD, the entity could decrease a guaranteed minimum bit rate and/or other quality of service level of the bearer.
