Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in controlling uplink data transmission to avoid network congestion, particularly as new services and applications with diverse requirements emerge.
Innovation Solution
The proposed method involves a terminal device receiving uplink maximum bit rate information from a network device for each logical channel, allowing the terminal device to allocate uplink resources based on these rates to implement rate control and reduce network congestion risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the terminal device allocates uplink resources to logical channels without rate control, then the data transmission efficiency is improved, but the network congestion risk increases
Solution Approach 1:
The patent applies parameter changes by introducing uplink maximum bit rate (UMBR) as a control parameter for each logical channel. The network device configures UMBR values that dynamically adjust the transmission rate limits, allowing the system to maintain high data transmission efficiency while preventing network congestion through regulated bit rates.
Solution Approach 2:
The patent implements feedback mechanisms where the network device monitors the uplink transmission status and adjusts the UMBR configurations accordingly. When network congestion is detected, the network device reduces the UMBR values for affected logical channels, creating a feedback loop that maintains system stability while allowing high throughput during normal conditions.
2Speed
If the terminal device allocates large quantity of uplink resources to a logical channel, then the uplink bit rate of the logical channel is high, but the network congestion risk increases
Solution Approach 1:
The patent uses parameter changes by configuring UMBR as an upper bound parameter for each logical channel's bit rate. This allows the system to achieve high uplink bit rates when needed while automatically preventing excessive rates that would cause network congestion, as the UMBR parameter acts as a hard limit on resource allocation.
3Reliability
If the network device configures uplink maximum bit rate for each logical channel, then the rate control is improved, but the signaling overhead increases
Solution Approach 1:
The patent applies segmentation by dividing the rate control configuration into logical channel-specific UMBR parameters. Instead of implementing a single system-wide rate limit, the network device configures individual UMBR values for each logical channel, allowing precise control where needed while reducing overall signaling overhead through targeted configuration.
Solution Approach 2:
The patent implements partial action by applying UMBR configuration only to logical channels that require rate control, rather than uniformly configuring all channels. This selective approach improves rate control precision for critical channels while minimizing the signaling overhead associated with configuring every logical channel.

AI summary
This application provides example data transmission control methods and example apparatuses. One example method includes receiving, by a terminal device, first information from a network device, where the first information indicates an uplink maximum bit rate of each of at least one logical channel. The terminal device can then allocate an uplink resource to one or more logical channels in the at least one logical channel based on the uplink maximum bit rate.
