Access Control Message Generation for Signaling Burden Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing access control mechanisms in communication networks face challenges in managing traffic congestion and resource allocation, leading to increased signaling burdens and inefficient service provision, particularly when multiple user equipment (UE) access the network simultaneously.
Innovation Solution
A method and apparatus that generate and send access control messages with specific access control parameters based on traffic classes or access classes to UE, allowing them to determine whether to initiate access, thereby reducing signaling burdens and enabling more precise and flexible control over network resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If access control parameters are frequently updated to ensure fair resource sharing among UEs, then resource allocation fairness is improved, but signaling burden on the network is aggravated
Solution Approach 1:
The patent segments the access control mechanism by introducing traffic class-specific parameters (ac-BarringForPSData, ac-BarringForPSSignaling) in addition to traditional access class parameters. This segmentation allows differentiated control for different traffic types without requiring frequent updates of general access control messages, thereby reducing overall signaling burden while maintaining fairness.
Solution Approach 2:
The patent enables dynamic access control by allowing the network to selectively update only the specific access control parameters relevant to current traffic conditions rather than broadcasting general system message changes. This dynamic approach reduces unnecessary signaling while maintaining adaptability to changing network conditions.
2Quantity of substance
If PS traffic is set to always-on to reduce signaling burden, then signaling burden is reduced, but access control flexibility is worsened
Solution Approach 1:
The patent applies local quality by introducing traffic-class-specific access control parameters that allow different access policies for different traffic types (data vs. signaling). This enables precise local control over PS traffic access without requiring changes to the overall always-on PS traffic mechanism, thus maintaining signaling efficiency while improving access control flexibility.
Solution Approach 2:
The patent changes the access control parameters from generic access class-based control to traffic class-based control (ac-BarringForPSData, ac-BarringForPSSignaling). This parameter change enables the network to control access flexibility for PS traffic without affecting the always-on nature of PS connections, resolving the contradiction between signaling burden and access control flexibility.
3Ease of operation
If conventional ACB mechanism is used to control access, then access control is provided, but signaling burden increases due to frequent parameter updates
Solution Approach 1:
The patent segments the access control functionality into traffic class-specific parameters (ac-BarringForPSData for data traffic, ac-BarringForPSSignaling for signaling traffic). This segmentation allows the network to control different traffic types independently, reducing the need for frequent general access control updates and thereby reducing signaling burden while maintaining access control capability.

AI summary
An access control method and apparatus are provided. The method includes: generating, by a network device, an access control message that includes an access control parameter, where the access control message is used to instruct user equipment to determine, according to the access control parameter after receiving the access control message, whether to initiate access, and the access control parameter includes an access control parameter based on a traffic class or an access control parameter based on an access class; and sending, by the network device, the access control message to the UE. The technical solutions of the present invention may reduce a signaling burden on a network and may enable the network device to provide more precise and flexible control of the UE.
