Network Load Distribution via Priority-Based Terminal Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During disasters, mobile communication networks face increased loads due to unmanaged terminal access, leading to processing capability degradation and service quality deterioration, as existing methods fail to effectively distribute terminal connections across available networks.
Innovation Solution
A communication apparatus and method that transmit and manage list information associating network IDs with priorities and identification information, allowing terminal devices to select and connect to networks with higher priorities, thereby distributing the load and preventing congestion.

1Ease of operation
If terminals randomly access EPC using unique terminal information (IMSI/IMEI) during disasters, then terminal connection is enabled, but load on EPC rapidly increases causing processing capability degradation
Solution Approach 1:
The invention segments the terminal population into multiple groups based on terminal information (IMSI/IMEI) and assigns different access timing patterns to each group. This segmentation prevents simultaneous random access by all terminals, thereby reducing the peak load on EPC while maintaining connection availability for all terminals across disaster-affected networks.
Solution Approach 2:
The invention implements periodic access timing for different terminal groups during disasters, where each group accesses EPC at different time intervals. This periodic distribution of access requests prevents load concentration and allows EPC to process terminal connections at a manageable rate while still providing service to all terminals.
2Reliability
If all terminals connect to alternative networks during disasters, then service continuity is maintained, but network load distribution becomes unbalanced causing congestion on specific networks
Solution Approach 1:
The invention applies different access timing characteristics to different terminal groups based on their local conditions and network preferences. By customizing access patterns for specific terminal groups rather than applying a uniform approach, the system achieves better load distribution across alternative networks while maintaining service continuity for all terminals.
Solution Approach 2:
The invention changes the access timing parameter for different terminal groups during disaster conditions. By modifying the timing characteristics (delay intervals, access windows) based on terminal group identification, the system distributes load across multiple networks more effectively while ensuring all terminals can access services.

AI summary
Providing a communication apparatus that are capable of suppressing a sudden increase in load on a network is an object when a disaster occurs. A communication apparatus according to the present disclosure includes a transmission unit configured to transmit list information in which a plurality of network IDs indicating a network available to a terminal device when a disaster occurs, a priority of the network ID, and identification information are associated with one another, the identification information being used when one network ID is selected from among a plurality of network IDs having the same priority, among the plurality of network IDs.
