Travel-Route Paging With Selective Base-Station Broadcasting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems waste resources by triggering all base stations in a tracking area to send paging signals when locating a terminal, leading to inefficient use of communication resources.
Innovation Solution
A method and apparatus that determine target base stations along a terminal's travel route and send paging signals only to these stations, reducing the number of base stations broadcasting paging signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all base stations in the tracking area are triggered to send paging signals, then the terminal can be reliably paged, but communication resources are wasted
Solution Approach 1:
The tracking area is segmented into multiple travel routes, and base stations are selectively activated based on which segment the terminal is likely to be in. Instead of activating all base stations in the entire tracking area, the system divides the area and activates only the relevant segments, reducing resource waste while maintaining paging reliability.
Solution Approach 2:
Different base stations are activated based on local conditions - specifically, which base stations correspond to cells that the terminal's travel route passes through. This localized activation strategy ensures that paging signals are sent only to base stations where the terminal is actually located or will be located, rather than uniformly activating all base stations in the tracking area.
2Reliability
If all base stations in the tracking area broadcast paging signals, then the terminal will receive the paging signal, but the number of base stations using communication resources increases
Solution Approach 1:
The tracking area is divided into multiple travel routes, and the system determines which specific route the terminal is likely to follow. Only base stations corresponding to cells on that specific route are activated to broadcast paging signals, significantly reducing the quantity of base stations using communication resources compared to activating all base stations in the tracking area.
Solution Approach 2:
The system extracts and identifies the specific subset of base stations that are relevant to the terminal's location and movement pattern. By taking out only the necessary base stations from the complete set of tracking area base stations, the system reduces resource consumption while ensuring the terminal receives paging signals.

AI summary
A paging method, comprising: receiving a travel route of a terminal; determining a target base station corresponding to a cell through which the travel route passes; and if the terminal is to be paged, sending to the target base station paging signals used for paging the terminal so that the target base station broadcasts the paging signals. According to embodiments of the present disclosure, a target base station may be determined according to a cell through which a travel route of the terminal passes, and then the target base station broadcasts paging signals. When a terminal is located in a certain tracking area, a travel route of the terminal generally will not pass through cells corresponding to all of the base stations in the tracking area, but will only pass through cells corresponding to some of the base stations in the tracking area.
