Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rate limiting methods in communication systems fail to meet the requirements of 5G application scenarios, particularly in managing aggregate bit rates for network slices in terminal devices.
Innovation Solution

Engineering Contradiction Analysis
1Adaptability or versatility
If conventional rate limiting methods are used to limit aggregate bit rate for non-GBR QoS flows, then the network can control data rates, but the method cannot satisfy current 5G application scenarios requiring network slice-level rate limiting
Solution Approach 1:
The patent segments the rate limiting mechanism at the network slice level rather than treating all QoS flows uniformly. Each network slice is assigned independent maximum data rate parameters (first maximum data rate for downlink, second maximum data rate for uplink), allowing differentiated rate control for different slice types and service requirements in 5G scenarios.
Solution Approach 2:
The patent applies local quality control by enabling each network slice to have its own specific rate limiting parameters and characteristics. The base station determines and enforces slice-specific maximum data rates based on local network conditions and slice requirements, rather than applying a uniform rate limit to all terminal devices.
2Reliability
If the base station enforces maximum data rates for all network slices, then quality of service is improved, but network resources may be allocated inefficiently
Solution Approach 1:
The patent implements dynamic rate limiting where the base station determines maximum data rates for network slices based on real-time local network conditions and slice requirements. The base station can independently determine different maximum data rates for different slices and adjust these rates dynamically to optimize both quality of service and resource allocation efficiency.
Solution Approach 2:
The patent changes the rate limiting parameters from a uniform aggregate bit rate to slice-specific parameters including first maximum data rate for downlink and second maximum data rate for uplink. This allows flexible parameter configuration for each network slice to balance quality of service requirements with network resource availability.
3Manufacturing precision
If the network provides detailed rate limiting configuration for each network slice, then configuration precision is improved, but the complexity of network management increases
Solution Approach 1:
The patent achieves universality by establishing a standardized framework where the base station handles rate limiting determination for all network slices through a unified process. The core network network slice selection function provides slice identification, and the base station applies consistent rate limiting logic across different slice types, reducing management complexity while maintaining precision.
Data Source
AI summary
The disclosure provides communication methods and apparatuses. One example method includes receiving, by a first network device, a first message from a second network device, where the first message includes network slice configuration information. The network slice configuration information is used to indicate a maximum data rate provided by each of n network slices for a terminal device, and n is an integer greater than or equal to 1. In response to the received first message, the first network device sends a second message to the second network device.
