Mobile Station Access Restriction via Class-Based Rate Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile communication systems face issues with frequent updates of notification information for access restriction, leading to increased radio section occupation and battery consumption, and require notification of a large number of restriction rates in LTE systems due to independent access restriction for each communication service.
Innovation Solution
A method and system that restrict connection request transmission processing by transmitting notification information for restriction rates specific to each access class and traffic class, allowing mobile stations to determine blockage based on generated random numbers, thereby reducing the frequency of notification checks and the number of restriction rates notified.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If notification information is updated periodically to notify access restriction, then access restriction can be implemented, but radio section is occupied by frequent paging signals and battery consumption increases
Solution Approach 1:
The mobile station determines access restriction status in advance by comparing its access class against the notified restriction information before attempting connection requests. This preliminary determination avoids the need for frequent periodic updates and paging signal receptions, thereby reducing battery consumption while maintaining reliable access restriction implementation.
2Reliability
If notification information is updated periodically to notify access restriction, then access restriction can be implemented, but radio section is occupied by frequent paging signals
Solution Approach 1:
The system notifies access restriction information to mobile stations in advance, allowing them to determine their restriction status before connection attempts. This eliminates the need for frequent periodic updates and paging signals, freeing up radio section resources while maintaining reliable access restriction.
3Adaptability or versatility
If access restriction is performed independently for each communication service in LTE, then service-specific restriction is achieved, but a very large number of restriction rates need to be notified
Solution Approach 1:
The notification information is segmented into two independent parts: access class restriction information and service type restriction information. This segmentation allows the system to maintain service-specific restriction capabilities while significantly reducing the total number of restriction rates that need to be notified, as each part can be independently managed and updated.
Solution Approach 2:
The restriction control is shifted from the network side to the mobile station side. Instead of the network managing and notifying numerous service-specific restriction rates, the mobile station autonomously determines restriction status by comparing its access class and service type against the notified restriction information, effectively moving the control dimension from network-centric to device-centric.

AI summary
A transmission process restriction method according to the present invention includes the steps of transmitting a notification information notifying of a restriction rate for each access class and a restriction rate for each traffic class, causing the mobile station to determine a restriction rate of the mobile station on the basis of the notification information received by the mobile station, an access class of the mobile station, and a traffic class of the mobile station, causing the mobile station to compare a random number generated by the mobile station to the restriction rate of the mobile station, and causing the mobile station to decide whether or not to block the connection request transmission processing in accordance with a result of the comparison.
