TMGI-Based Access Triggering for M2M Network Load Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In M2M communication systems, concurrent reporting from a large number of devices can lead to network congestion and breakdown due to the heavy loading of paging channels, especially in LTE systems, where separate paging of each user occupies significant resources and affects normal paging operations.
Innovation Solution
A method utilizing temporary mobile group identities (TMGI) within existing MBMS technology to generate and send access trigger messages, allowing for controlled packet access by triggering groups of users, thereby reducing network impact and optimizing resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate paging of each user is used to control access, then access control effectiveness is improved, but paging resource occupation increases significantly
Solution Approach 1:
The patent merges multiple user paging operations into a single group paging message by introducing a group identity identifier. Instead of sending separate paging messages to each user, the network sends one paging message that contains a group identifier, and all users belonging to that group receive and process the same paging message, thereby controlling access while significantly reducing paging resource consumption.
2Productivity
If a large amount of concurrent user reporting is allowed, then data reporting capability is improved, but network load increases causing congestion or breakdown
Solution Approach 1:
The patent applies preliminary action by pre-configuring users with group identity identifiers before they need to report data. When uplink data arrives, the network can immediately use the pre-assigned group identifier to page the appropriate group of users, enabling controlled concurrent access without causing network overload. This pre-organization of users into groups with shared identifiers allows efficient load management.

AI summary
Embodiments of the present invention provide a method for controlling packet access, a network side device, a terminal device and a communication system. The method includes: generating an access trigger message, where the access trigger message carries a temporary mobile group identity TMGI allocated to a user equipment UE; and sending the access trigger message to packet trigger an access operation of the UE for the TMGI. In the embodiments of the present invention, the group identity TMGI already existing in an MBMS can be used as the group identity of packet triggering UE access, and the access trigger message carrying the TMGI can be correspondingly generated and sent so as to trigger an access operation of the UE belonging to the TMGI, thereby implementing the function of the packet triggering user access.
