Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the control layer device interconnects with a large number of base stations, base station controllers and other gateway devices, then the service control and charging function becomes more refined, but the signaling load on the interface between the control layer device and the forwarding layer device increases significantly

Engineering Contradiction:

Improveservice control and charging functionVSAvoidsignaling load

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent segments the gateway device into control layer device and forwarding layer device, with the forwarding layer device handling transparent transmission of path management signaling. This segmentation reduces the signaling load on the control layer device by offloading transparent transmission tasks to the forwarding layer device, while maintaining refined service control and charging functions.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The forwarding layer device acts as an intermediary between the control layer device and external devices (base stations, base station controllers). It handles the transparent transmission of signaling and information, reducing the direct signaling burden on the control layer device while enabling refined service control through the control layer device's policy management capabilities.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the control layer device identifies the state of opposite-end devices and performs processes on failed paths, then path management control is achieved, but misjudgment of path state and opposite-end device state occurs due to interface failures

Engineering Contradiction:

Improvepath management controlVSAvoidpath state identification accuracy

Core Design Contradiction:

ReliabilityVSMeasurement precision

Solution Approach 1:

The forwarding layer device serves as an intermediary that maintains accurate knowledge of path states and opposite-end device states through transparent transmission. When interface failures occur between control and forwarding layers, the forwarding layer device can provide accurate path state information to the control layer device, preventing misjudgment while maintaining reliable path management control.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements feedback mechanisms where the forwarding layer device reports path state information and opposite-end device state information to the control layer device. This feedback loop ensures accurate state identification even when direct control-layer interfaces fail, as the forwarding layer device maintains continuous monitoring and reporting capabilities.

Inventive Principle:

Principle #23Feedback

3Ease of operation

If the control layer device processes all signaling and the forwarding layer device only performs transparent transmission, then clear division of labor is achieved, but the control layer device experiences significant signaling load and potential misjudgment

Engineering Contradiction:

Improvedivision of laborVSAvoidsignaling load on control layer device

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The patent further refines the segmentation by dividing signaling processing responsibilities: the control layer device handles policy control and charging signaling, while the forwarding layer device handles user plane data and transparent transmission of path management signaling. This refined segmentation reduces the control layer device's signaling load while maintaining clear division of labor.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The forwarding layer device performs partial signaling processing functions (transparent transmission of path management signaling) in addition to its primary data forwarding role. This partial action reduces the burden on the control layer device without requiring complete redistribution of all signaling functions, achieving load reduction while maintaining operational simplicity.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A method and a device for processing a communication path are provided. The method includes: obtaining a path processing parameter from local configuration information or from a control layer device, obtaining path information and/or a restarting counter parameter from the control layer device; increasing a path with an opposite-end device when the path information is of increasing a path, identifying the state of the path and/or the state of the opposite-end device using the path processing parameter and/or the restarting counter parameter the opposite-end device; reporting the fault state of the path and/or the reset state of the opposite-end device to the control layer device when the path fails and/or the opposite-end device is reset, releasing sessions on the failed path and/or on a path connected with the reset opposite-end device.
