Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in managing group-related traffic efficiently, particularly in scenarios involving multiple terminals, where mobilizing wireless resources can affect normal operations and other traffic, necessitating effective bandwidth management and dynamic scheduling.
Innovation Solution
A communication method and device that involve receiving and transmitting transmission rate parameters to measure and control the transmission rates of multiple terminal devices within a group, using mechanisms like Group Maximum Bit Rate (Group MBR) and Aggregated Guaranteed Bit Rate (Aggregated GBR) to manage bandwidth and adjust communication rates dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple terminal devices are mobilized to carry out group-related traffic, then communication coverage and group connectivity are improved, but bandwidth consumption increases and interference with other traffic occurs
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the transmission rate parameters (Group MBR and Aggregated GBR) based on network conditions and group traffic requirements. The network device configures different transmission rate parameters for different groups, allowing the system to adapt bandwidth allocation to actual needs rather than allocating fixed maximum bandwidth to all groups, thus reducing overall bandwidth consumption while maintaining necessary group connectivity.
2Ease of operation
If transmission rate parameters are configured for each terminal device in a group, then individual transmission control is improved, but device complexity and management overhead increase
Solution Approach 1:
The patent merges the transmission rate control for multiple terminal devices within a group by configuring group-level parameters (Group MBR) and aggregated parameters (Aggregated GBR) at the network device. Instead of managing individual parameters for each terminal, the network device configures these aggregated parameters that apply to the entire group, significantly reducing management overhead while still enabling effective transmission control for all group members through the relay device.
3Productivity
If dynamic scheduling is implemented to manage bandwidth, then resource utilization is improved, but system complexity and scheduling overhead increase
Solution Approach 1:
The patent implements preliminary action by pre-configuring transmission rate parameters (Group MBR and Aggregated GBR) for terminal devices before actual data transmission occurs. The network device determines and configures these parameters based on predicted traffic patterns and network conditions, allowing the relay device and terminal devices to operate within predefined rate limits without requiring complex real-time scheduling decisions, thus improving resource utilization while reducing scheduling overhead.
