Solution Overview

Problem

In complex mobile communication networks with multiple radio access technologies, service migration processes often neglect service performance and user experience, leading to suboptimal user experience due to lack of direct and comprehensive information transfer between source and target network elements.

Innovation Solution

An optimized processing method and apparatus for service migration that acquires and reports detailed service performance information, including forward and reverse service rates, delays, packet error rates, and throughput, enabling real-time optimization of service migration policies and parameters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If network control mode is used for service migration, then the source side can trigger the migration process, but the source side cannot acquire service performance information after migration due to limited interface capabilities

Engineering Contradiction:
Improveautomation of service migration triggeringVSAvoidservice performance information after migration
Core Design Contradiction:
Extent of automationVSLoss of information

Solution Approach 1:

The patent introduces the target side as an intermediary that collects service performance information after migration and transfers it to the source side. This resolves the information loss problem by using the target side as a mediator to bridge the communication gap between migration trigger and performance assessment.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent establishes a feedback mechanism where the target side sends service performance information back to the source side after migration. This enables the source side to optimize migration parameters based on actual performance data, creating a closed-loop control system.

Inventive Principle:
Principle #23Feedback

2Loss of information

If existing parameter transfer methods are used, then state parameters like load information can be transferred, but actual service performance and user experience cannot be directly reflected

Engineering Contradiction:
Improvestate parameter transfer capabilityVSAvoidservice performance measurement accuracy
Core Design Contradiction:
Loss of informationVSMeasurement precision

Solution Approach 1:

The patent changes the type of parameters being transferred from generic state parameters (load information, routing information) to specific service performance parameters (service rates, delays, packet error rates). This parameter transformation enables direct measurement of actual service performance and user experience.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If service migration is performed without considering service performance changes, then migration can be executed quickly, but user experience deteriorates due to inappropriate migration parameters

Engineering Contradiction:
Improvemigration execution speedVSAvoiduser experience quality
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent performs preliminary actions by collecting service performance information after migration before using it to optimize subsequent migration decisions. This allows the system to learn from past migrations and improve future migration parameter selection, balancing speed and quality.

Inventive Principle:
Principle #10Preliminary action

AI summary

Provided are an optimized processing method and apparatus for service migration of a terminal. According to the optimized processing method, when the terminal conducts service transmission with a network or when the terminal performs service migration between a source network element and a target network element, service performance information of the terminal is acquired. By means of the technical solution, the technical problem in the related art that the service performance or service experience, etc. of a terminal is not taken into account during service transmission between a terminal and a network or during service migration of a terminal is solved, so the service performance and service experience can be obtained when the terminal conducts service transmission or service migration, thereby providing a powerful support for optimizing the service migration or service transmission of the terminal and improving the experience of a user.
