Solution Overview

Problem

Conventional load re-balancing mechanisms in communication networks can only migrate users based on load status and do not provide a specific process for user equipment (UE) type-based migration, leading to inefficiencies in network resource allocation.

Innovation Solution

A method and system that determine the type of user equipment (UE) upon receiving an access request and migrate it to a corresponding network device, ensuring that dedicated type UE is served by a dedicated type network device and non-specified type UE is served by a non-dedicated type network device, combining load balancing and load re-balancing mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional load re-balancing mechanism is used to migrate UE based on load status, then network resource allocation is achieved, but UE type-based migration efficiency is poor

Engineering Contradiction:
Improvenetwork resource allocation efficiencyVSAvoidUE type-based migration capability
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by differentiating migration strategies based on UE type. The network device determines whether a UE is a first type (e.g., voice service UE) or second type (e.g., data service UE) and applies different migration rules: first type UEs are migrated only when necessary (e.g., network device failure), while second type UEs are actively migrated during load re-balancing. This targeted approach improves overall network resource allocation efficiency while maintaining adaptability to different service requirements.

Inventive Principle:
Principle #3Local quality

2Reliability

If dedicated type network device is assigned to dedicated type UE, then service quality is improved, but network device complexity increases

Engineering Contradiction:
Improveservice qualityVSAvoidnetwork device configuration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the UE population into different types (first type and second type) based on service requirements. Network devices are similarly segmented into dedicated type network devices for first type UEs and general network devices for second type UEs. This segmentation enables specialized service handling without requiring complete reconstruction of existing devices, as the patent leverages existing device capabilities while organizing them into specialized groups through configuration rather than hardware modification.

Inventive Principle:
Principle #1Segmentation

3Productivity

If load re-balancing is performed without UE type consideration, then network load is balanced, but service continuity for specific UE types may be affected

Engineering Contradiction:
Improveload balancing efficiencyVSAvoidservice continuity
Core Design Contradiction:
ProductivityVSStability of the object's composition

Solution Approach 1:

The patent implements dynamic migration rules that adapt to UE type and network conditions. For first type UEs, the migration rule is dynamic and restrictive: migration occurs only when the serving network device fails or becomes unavailable, ensuring service continuity while allowing necessary migrations. For second type UEs, the migration rule is dynamic and flexible: active migration is performed during load re-balancing operations. This dynamic approach maintains service continuity for critical UEs while enabling efficient load balancing for non-critical UEs.

Inventive Principle:
Principle #15Dynamics

AI summary

The embodiment of the invention discloses a method for re-balancing a load, a method for migrating a load, a device and a system using the same. The method for re-balancing a load comprises: determining a type of a UE after receiving an access request from the UE by a first network device; determining whether the UE is to be migrated according to the type of the UE; and if yes, migrating the UE to a second network device whose type corresponds to the type of the UE. According to the embodiments of the present disclosure, the CN nodes may be balanced according to the type of the UE.
