Solution Overview

Problem

The existing methods for service equalization in multi-network environments are not flexible and do not efficiently utilize network resources, as they require transferring all services of a terminal as a whole between different networks, leading to suboptimal resource allocation and user experience.

Innovation Solution

A method and apparatus for service equalization that allows partial transfer of service bearers between networks based on service equalization indication information, including identification of terminals, service bearers, destination networks, and network load thresholds, enabling selective and efficient resource allocation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If all services of a terminal are transferred as a whole between different networks during service equalization, then the service equalization can be implemented, but the flexibility of service allocation is reduced and network resources cannot be fully utilized

Engineering Contradiction:
Improveservice allocation flexibilityVSAvoidnetwork resource utilization efficiency
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent segments the service bearers of a terminal into different groups that can be independently transferred between networks. Instead of transferring all services as a whole, the network can selectively transfer specific service bearers (e.g., high-rate services to 3G/LTE networks, voice services to 2G networks) based on network conditions and service requirements, thereby improving both flexibility and resource utilization efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements partial transfer of service bearers rather than complete transfer. The network can transfer only the necessary portion of services that need equalization while keeping other services on the original network, avoiding unnecessary resource consumption and maintaining service continuity where not needed.

Inventive Principle:
Principle #16Partial or excessive action

2Reliability

If multiple networks are deployed to meet diverse service demands, then service quality can be improved, but network resource waste increases and operational pressure rises

Engineering Contradiction:
Improveservice qualityVSAvoidnetwork resource waste
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The patent changes the parameter of service bearer transfer from all-or-nothing to selective partial transfer. By adjusting which service bearers are transferred based on service type, network load, and QoS requirements, the system optimizes resource utilization across multiple networks while maintaining service quality.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements feedback mechanisms where the network monitors service bearer performance and network conditions, then dynamically adjusts service equalization decisions. This feedback loop ensures that services are allocated to appropriate networks based on real-time conditions, preventing resource waste while maintaining service quality.

Inventive Principle:
Principle #23Feedback

3Productivity

If service equalization transfers all services between networks, then load balancing can be achieved, but the complexity of service management increases

Engineering Contradiction:
Improveload balancing efficiencyVSAvoidservice management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent simplifies service management by segmenting service bearers into transferable and non-transferable categories, and further dividing transferable services into groups that can be independently managed. This segmentation reduces the complexity of managing service equalization by allowing selective rather than comprehensive transfer decisions.

Inventive Principle:
Principle #1Segmentation

AI summary

Disclosed are a method and apparatus for service equalization, the method comprising: a source wireless access network element receiving service equalization indication information transmitted by a core network; and the source wireless access network element transferring, according to the service equalization indication information, parts of or all of service bearers of a terminal in a source network to a destination network, wherein the service bearers are user plane connection bearers established for transmitting terminal data. The invention solves the technical problems in the related art that the scheduling of service equalization is not flexible and the utilization of the network resource is not reasonable, which are caused by transferring all the services of a terminal as a whole between different networks at the time of service equalization, therefore enabling parts of service bearer transfer of a terminal, increasing the flexible of the service equalization, and realizing the reasonable utilization of the network resource.
