Communication Equipment eDRX State Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication equipment cannot accurately inform users whether it is performing extended Discontinuous Reception (eDRX) operations due to the lack of consideration for base station availability, despite configuration parameter acquisition, leading to unclear operational states.
Innovation Solution
The communication equipment negotiates with a management apparatus to acquire configuration parameters for eDRX and checks base station availability through notification information, then notifies external equipment of the actual operation state, including whether eDRX is enabled and available at the base station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the communication equipment acquires eDRX configuration parameters from the management apparatus, then the power-saving capability is improved, but the operational state information becomes inaccurate when the base station does not support eDRX
Solution Approach 1:
The communication equipment checks notification information from the base station to determine whether eDRX is actually available, and notifies external equipment of the actual operation state. This feedback mechanism ensures that the reported operational state accurately reflects whether eDRX is being used, resolving the contradiction between power-saving configuration and accurate state information.
Solution Approach 2:
The communication equipment performs a preliminary check of the base station's eDRX availability through notification information before actually implementing eDRX operations. This preliminary action prevents inaccurate operational state reporting by verifying eDRX support in advance.
2Loss of information
If the communication equipment notifies external equipment of the eDRX operation state, then the user awareness is improved, but the device complexity increases due to additional negotiation and checking processes
Solution Approach 1:
The controller performs multiple functions: it negotiates eDRX parameters with the management apparatus, checks base station eDRX availability through notification information, determines the actual operation state, and notifies external equipment. By consolidating these functions in a single controller, the patent avoids adding separate dedicated components, thus limiting the increase in device complexity while maintaining full operational state transparency.
3Measurement precision
If the communication equipment checks base station eDRX availability through notification information, then the operational accuracy is improved, but the communication overhead with the base station increases
Solution Approach 1:
The base station includes eDRX availability information in its notification information broadcasts. The communication equipment simply checks this self-provided information without requiring additional dedicated inquiry messages. This self-service approach allows accurate eDRX availability detection while minimizing additional communication overhead, as the information is already being transmitted by the base station for other purposes.

AI summary
A communication equipment for which an extended DRX is available negotiates with a management apparatus included in a network to acquire a configuration parameter of the extended DRX. The communication equipment checks whether the base station is for which the extended DRX is available based on notification information received from the base station. The communication equipment notifies the external equipment of an operation state indicating whether the communication equipment is performing an extended DRX operation based on whether a configuration parameter of the extended DRX is acquired and whether the base station is for which the extended DRX is available.
