Network Re-establishment Trigger for Gateway Reset
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In EPS mobile communications networks, network connection re-establishment after gateway resetting is delayed due to untimely detection, especially when serving gateways and data gateways are integrated, leading to potential data loss and poor user experience.
Innovation Solution
A method where a data gateway sends a network connection re-establishment trigger message to an access node upon detecting a downlink packet, allowing real-time re-establishment of the network connection by determining the type of gateway resetting and initiating appropriate re-establishment procedures, even in integrated gateway scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional network connection re-establishment methods are used after gateway resetting, then the system follows standardized procedures, but the re-establishment time is delayed and data loss occurs
Solution Approach 1:
The patent applies preliminary action by having the access node proactively detect gateway reset status and pre-prepare for connection re-establishment before actual data loss occurs. The access node monitors gateway health and initiates re-establishment procedures as soon as reset is detected, rather than waiting for traditional timeout-based detection mechanisms.
Solution Approach 2:
The patent implements feedback mechanisms where the access node continuously monitors gateway status and receives real-time notifications about gateway resets. This feedback loop enables the access node to immediately respond to gateway reset events and trigger appropriate re-establishment procedures, reducing the time delay compared to traditional methods.
2Device complexity
If serving gateway and data gateway are integrated and reset together, then device complexity is reduced, but traditional re-establishment methods fail to work properly
Solution Approach 1:
The patent applies universality by designing a unified re-establishment mechanism that works for both separate gateway scenarios and integrated gateway scenarios. The access node is equipped with the capability to handle reset events from either serving gateways or data gateways independently or together, making the system adaptable to different network architectures without requiring separate procedures.
Solution Approach 2:
The patent uses parameter changes by detecting the specific reset status parameters of gateways and adjusting the re-establishment procedure accordingly. When gateways are integrated and reset together, the system recognizes this parameter state and executes appropriate re-establishment logic that accounts for the combined reset scenario, ensuring reliability regardless of gateway configuration.
3Ease of operation
If reset detection mechanism operates with traditional timing, then system operation is simple, but detection is not timely and downlink data is lost
Solution Approach 1:
The patent implements real-time feedback mechanisms where the access node continuously monitors gateway status through active probing or event-driven notifications. This feedback enables precise detection of gateway reset events as they occur, significantly improving detection timing accuracy compared to traditional periodic or timeout-based detection methods.
Solution Approach 2:
The system performs preliminary detection actions by continuously monitoring gateway health status before actual data transmission issues occur. The access node maintains readiness to detect reset events immediately, rather than waiting for standard operational cycles to complete, thereby achieving timely detection without overly complicating the detection mechanism.

AI summary
An embodiment of the present invention discloses a network connection re-establishment method, including: detecting whether gateway resetting occurs, and if it is detected that gateway resetting occurs, sending a network connection re-establishment trigger message to an access node when a downlink packet sent by a packet data network is received, where the access node re-establishes, according to a type of the gateway resetting, a network connection corresponding to the downlink packet, and the type of the gateway resetting is resetting of a data gateway or resetting of a serving gateway. The present invention can be used to quickly re-establish a network connection, and can be applied to a situation in which a serving gateway and a data gateway are integrated.
