Sequential Access Control Check Items for Wireless Network Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current access control mechanisms in wireless communication systems, such as LTE, face challenges in managing network congestion and efficiently controlling terminal device access, leading to suboptimal user experience due to lack of flexibility and effectiveness in prioritizing access requests.
Innovation Solution
A method where a radio access network device sends access control information to terminal devices with a list of check items in a predetermined order, each containing target object information and result processing information, allowing devices to sequentially check and determine access based on matching attributes and statuses, with options for probability and prohibition durations, to flexibly manage access and alleviate congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional access control mechanisms (ACB, SSAC, ACDC) are used, then access control functionality is provided, but flexibility and effectiveness in prioritizing access requests are insufficient
Solution Approach 1:
The access control check items are segmented into multiple independent check items, each with specific target object information and result processing information. This segmentation allows the terminal device to perform sequential checks with different priorities and conditions, enhancing flexibility in access control while maintaining effectiveness through structured evaluation
Solution Approach 2:
The access control mechanism uses dynamic check items that can be configured with different target objects, result processing methods, and priorities. The system adapts to different access scenarios by dynamically selecting and evaluating appropriate check items in sequence, providing both flexibility and reliability
2Reliability
If multiple access control mechanisms are applied, then comprehensive access control is achieved, but check time increases
Solution Approach 1:
The access control check items are pre-configured with target object information, result processing information, and priorities. The terminal device performs sequential checks starting from highest priority items, allowing preliminary evaluation of access requests against multiple criteria without requiring exhaustive checking of all possible conditions
Solution Approach 2:
The sequential check mechanism allows the terminal device to skip lower priority check items once a decisive result is obtained from higher priority checks. This rushing through mechanism reduces overall check time while maintaining comprehensive access control evaluation

AI summary
Embodiments of this application provide an access control method, a terminal device, and a radio access network device. The method includes: receiving, by a terminal device, access control information sent by a radio access network device; when the terminal device needs to initiate access or a service, checking, by the terminal device, a first check item obtained in a predetermined order from a plurality of check items in the access control information; obtaining, by the terminal device when the terminal device belongs to a target object indicated by first target object information included in the first check item, a first check result based on the first check item; and when the first check item is not a last check item of the plurality of check items, determining, by the terminal device, the first check result as a final result based on the first check result and first result processing information of the first check item, or checking a second check item obtained in the predetermined order from the plurality of check items. According to the embodiments of this application, flexible access may be implemented.
