Network Access Control via Paging Message Classification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G networks, User Equipment (UE) faces inefficiencies in random access due to unclear access restrictions when attempting to connect to a target cell, as existing methods lack clear criteria for determining whether access is allowed, leading to increased time spent on access control and reduced network efficiency.
Innovation Solution
A method where the UE determines its access category based on a paging message from the base station, matching access control information to determine if access is allowed, thereby streamlining the access process and reducing signaling overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If UE performs random access without clear access control information, then access process is simpler, but access control accuracy deteriorates and time consumption increases
Solution Approach 1:
The base station performs preliminary action by including access category information in the paging message before the UE attempts random access. This allows the UE to pre-determine its access category and perform access control checks in advance, rather than discovering access restrictions during the random access process. The access control information is prepared and transmitted ahead of time, enabling the UE to make informed access decisions without extending the actual access procedure.
2Ease of operation
If UE performs random access without clear access control information, then access process is simpler, but network access efficiency deteriorates
Solution Approach 1:
The base station provides feedback to the UE by including access category information in the paging message. This feedback mechanism allows the UE to receive explicit guidance about its access category and the access control status of the target cell before attempting random access. The UE uses this feedback information to determine whether access is permitted, thereby improving network access efficiency through informed decision-making rather than trial-and-error approaches.
3Loss of energy
If access control information is not included in paging message, then signaling overhead is reduced, but UE cannot determine access permission accurately
Solution Approach 1:
The patent extracts only the essential access control information (access category) and includes it in the paging message, rather than transmitting comprehensive access control parameters. This selective extraction approach provides the UE with sufficient information to determine access permission accurately while minimizing the increase in signaling overhead. The base station includes only the necessary access category identifier, which the UE uses to perform access control checks without requiring extensive additional signaling.

AI summary
The present disclosure provides a method and apparatus for controlling network access, said method comprising: determining access uniform classification information of a user equipment according to a paging message issued by a base station; according to said access uniform classification information, matching access control information of a target cell to obtain a match result; if said match result indicates that said user equipment has been permitted to access said target cell, then issuing a random access request to the target cell; the access control information of the target cell comprising: access control configuration parameters of the uniform classification information. Using the method for controlling network access provided by the present disclosure, when a user equipment is paged to access a network, it is possible to match, according to access uniform classification information designated for the user equipment by a base station, access control information configured on the basis of uniform classification information, and rapidly determine whether the user equipment is permitted to access a cell, thus improving the efficiency with which the user equipment randomly accesses the network.
