Solution Overview

Problem

The existing method of sending radio link failure (RLF) reports from a base station to an Integration Reference Point Manager (IRPManager) through an Integration Reference Point Agent (IRPAgent) in a best-effort mode results in a heavy load of information transfer and unnecessary processing for the IRPManager, as it receives redundant reports.

Innovation Solution

Implementing a method where the IRPAgent configures and subscribes to specific RLF report conditions, obtaining and sending only relevant reports to the IRPManager, thereby reducing the information load and processing redundant reports.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the base station sends all RLF reports to the IRPManager through the IRPAgent in best-effort mode, then complete RLF report information is available, but the information transfer load between IRPManager and IRPAgent becomes heavy

Engineering Contradiction:
ImproveRLF report information completenessVSAvoidinformation transfer load
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent extracts and filters only the necessary RLF report information that meets specific subscription conditions from the complete set of RLF reports. The IRPAgent selectively obtains and forwards only relevant RLF reports to the IRPManager based on configured subscription conditions, removing unnecessary information transfer while maintaining data completeness for required parameters.

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If the IRPManager receives all RLF reports, then all possible reports are available for processing, but the IRPManager processes redundant and useless reports increasing processing load

Engineering Contradiction:
Improvereport availabilityVSAvoidIRPManager processing efficiency
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent implements preliminary filtering of RLF reports at the IRPAgent before they reach the IRPManager. Subscription conditions are configured in advance, and the IRPAgent pre-processes RLF reports by comparing them against these conditions, obtaining only matching reports. This preliminary action prevents the IRPManager from receiving and processing redundant reports, thereby improving processing efficiency while maintaining adaptability to specific management applications.

Inventive Principle:
Principle #10Preliminary action

3Quantity of substance

If the IRPAgent filters RLF reports based on subscription conditions, then information transfer load is reduced, but the complexity of the IRPAgent increases

Engineering Contradiction:
Improveinformation transfer loadVSAvoidIRPAgent complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent implements partial filtering action at the IRPAgent level, where subscription conditions are configured to specify exactly which RLF reports need to be obtained. Rather than implementing complex filtering logic, the system uses a targeted approach where the IRPAgent obtains reports that match predefined subscription conditions. This partial action reduces information transfer load while keeping the IRPAgent complexity manageable by focusing only on necessary filtering criteria.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

Embodiments of the present invention provide a method and device for subscribing to an RLF report. The method includes: configuring, by an integration reference point manager, a subscription condition for an RLF report, for an integration reference point agent; and obtaining, by the integration reference point manager, an RLF report that is sent by the integration reference point agent and satisfies the subscription condition. The embodiments of the present invention can avoid the case in the prior art that a base station sends an RLF report obtained from a UE, to an IRPManager through an IRPAgent in a best-effort mode, thereby decreasing the load of information transferred between the IRPManager and the IRPAgent.
