Dynamic Neighbor Report Rate Control for Bearer Traffic Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, the transmission of neighbor reports on bearer channels can interfere with high-priority or delay-sensitive bearer traffic, impacting application performance due to the sharing of capacity with queued bearer traffic.
Innovation Solution
A wireless communication device adjusts the rate of neighbor reports based on characteristics such as queue length, priority, and delay sensitivity of the bearer traffic, transmitting them over the reverse-direction channel at a particular rate to minimize interference with bearer traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If neighbor reports are transmitted on bearer channels to utilize greater capacity, then transmission capacity is improved, but interference with bearer traffic increases
Solution Approach 1:
The patent applies dynamics by making the neighbor report transmission rate adjustable rather than fixed. The wireless communication device dynamically modifies the transmission rate based on real-time characteristics of queued bearer traffic, such as queue length and traffic type, allowing the system to adapt between utilizing bearer channel capacity and minimizing interference with applications.
Solution Approach 2:
The patent changes the transmission rate parameter of neighbor reports based on bearer traffic characteristics. When bearer traffic queue length is small or traffic is non-critical, the transmission rate increases to utilize capacity. When queue length is large or traffic is delay-sensitive, the transmission rate decreases to minimize interference, thus resolving the contradiction between capacity utilization and interference reduction.
2Reliability
If neighbor reports are transmitted at high rate to maintain handover performance, then handover capability is improved, but impact on delay-sensitive applications increases
Solution Approach 1:
The patent implements feedback by continuously monitoring bearer traffic characteristics (queue length, traffic type) and using this information to adjust neighbor report transmission rates. This closed-loop control ensures that handover performance is maintained when needed while minimizing delay to applications when traffic conditions require it.
Solution Approach 2:
The system dynamically adjusts the transmission rate of neighbor reports based on real-time bearer traffic conditions. When applications are delay-sensitive and queues are long, the transmission rate is reduced to minimize time loss. When handover is critical and traffic is non-critical, the rate increases to maintain reliability, thus resolving the contradiction between handover performance and application delay.
3Object-affected harmful factors
If neighbor reports are transmitted on signaling channels to avoid bearing channel interference, then application performance is improved, but channel capacity utilization decreases
Solution Approach 1:
The patent makes the transmission channel selection dynamic rather than static. The wireless communication device determines whether to transmit neighbor reports on signaling channels or bearer channels based on real-time bearer traffic characteristics. When bearer traffic is light, the device transmits on bearer channels to utilize capacity. When bearer traffic is heavy, the device switches to signaling channels to protect application performance, thus resolving the contradiction between capacity utilization and application performance.

AI summary
A wireless communication device (WCD) may determine that the WCD has bearer traffic queued for transmission to a radio access network (RAN). The WCD may be configured to transmit the bearer traffic and neighbor reports over a reverse-direction channel of the RAN. The neighbor reports may contain information related to wireless coverage areas. One or more characteristics of the bearer traffic may also be determined. Based on the one or more characteristics of the bearer traffic, the neighbor reports may be scheduled to be transmitted over the reverse-direction channel at a particular rate. The WCD may transmit the neighbor reports over the reverse-direction channel at the particular rate.
