Solution Overview

Problem

In 5G NR cellular networks, handover scenarios between different vendor configurations are inefficient due to incompatibilities and inconsistencies, compromising the network's performance.

Innovation Solution

Implementing a handover manager at each base station to facilitate the exchange and reconfiguration of handover parameters between source and target base stations, ensuring compatibility and smooth transitions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If handover parameters are exchanged between base stations from different vendors, then handover compatibility is improved, but system complexity increases due to vendor-specific parameter differences

Engineering Contradiction:

Improvehandover compatibilityVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a network controller as an intermediary between base stations from different vendors. This controller translates and reconciles vendor-specific handover parameters into a standardized format, enabling compatibility without requiring direct complex interactions between heterogeneous base stations. The intermediary handles the complexity centrally rather than distributing it across all base station interfaces.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent transforms vendor-specific handover parameters into a standardized parameter set through the network controller. By changing the parameter representation from proprietary formats to a unified standard, the system achieves interoperability while reducing the complexity of direct vendor-to-vendor parameter negotiation.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If handover parameters are reconfigured to ensure compatibility, then handover reliability is improved, but handover time increases

Engineering Contradiction:

Improvehandover reliabilityVSAvoidhandover time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent performs handover parameter reconfiguration in advance through the network controller before the actual handover occurs. By pre-translating and validating parameters during the handover preparation phase rather than during execution, the system ensures reliability while minimizing the time impact on the critical handover transition.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent maintains continuous parameter validation and adjustment through the network controller during the handover process. This continuous oversight ensures that compatibility is maintained throughout the transition without requiring repeated interruptions for parameter checks, thereby reducing overall handover time while preserving reliability.

Inventive Principle:

Principle #20Continuity of useful action

AI summary

Technologies for efficient handover in inter vendor handover scenario in a cellular network are described. One method include sending, by a source base station, a handover request to a target base station; exchanging a plurality of handover parameters with the target node; determining whether a matched set of the plurality of handover parameters exists; responsive to determining that the matched set exists, sending a notification regarding the matched set to the target base station; and performing handover with user equipment (UE) using the matched set of the plurality of handover parameters.
