Solution Overview

Problem

In communication electronics, excessively long no-response times during discontinuous reception (DRX) or power-saving states in user equipment lead to service interruptions and unnecessary device recovery procedures due to delayed GTP message responses, causing signaling overload in the network.

Innovation Solution

A GTP message sending device adjusts its message sending strategy based on received no-response time indications from user equipment, postponing or bringing forward message transmission to avoid triggering fault detection mechanisms and prevent service interruptions or device recoveries.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If user equipment uses discontinuous reception (DRX) or enters power-saving state for a long time, then electricity consumption of user equipment is reduced, but response time to network paging increases causing service interruption

Engineering Contradiction:
Improveelectricity consumption of user equipmentVSAvoidresponse time to network paging
Core Design Contradiction:
Use of energy by moving objectVSLoss of time

Solution Approach 1:

The network side performs preliminary actions by sending a no-response time indication to the GTP message sending device before the user equipment actually enters the power-saving state or before the DRX period begins. This allows the GTP message sending device to adjust its retransmission timer in advance, ensuring that message retransmissions are synchronized with the user equipment's wake-up times, thereby avoiding service interruption while maintaining power-saving benefits

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by having the GTP message response device send the no-response time indication back to the GTP message sending device. This feedback loop enables the sending device to adapt its retransmission strategy based on the actual power-saving behavior of the user equipment, resolving the contradiction between energy saving and response time

Inventive Principle:
Principle #23Feedback

2Reliability

If GTP message retransmission timer is set to default value, then message transmission follows standard protocol, but unnecessary device recovery procedures are triggered causing signaling overload

Engineering Contradiction:
Improvemessage transmission reliabilityVSAvoidsignaling overhead from device recovery procedures
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention changes the parameter of the retransmission timer value dynamically based on the no-response time indication received from the GTP message response device. Instead of using a fixed default timer value, the system adjusts the timer to match the user equipment's actual response characteristics, preventing premature timeout and subsequent device recovery procedures, thereby reducing signaling overhead while maintaining transmission reliability

AI summary

Embodiments of the present invention disclose a method and device for controlling sending of a GTP message, and a data sending method and device. The method for controlling sending of a GTP message includes: receiving, by a GTP message sending device, a no-response time indication of user equipment sent from a GTP message response device, where the no-response time indicates the no-response time of the user equipment in an implicit or explicit manner; and adjusting, by the GTP message sending device according to the no-response time of the user equipment indicated by the received no-response time indication of the user equipment, a time of sending a GTP message, where adjusting the time of sending the GTP message is specifically postponing the time of sending the GTP message as the no-response time of the user equipment increases, or bringing forward the time of sending the GTP message as the no-response time of the user equipment decreases. In this way, a service interruption of the user equipment or an unnecessary device recovery procedure on a network caused by an excessively long no-response time of a user is avoided.
