Source IP Address Selection for Service Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional IP address selection techniques in wireless communication networks often lead to service discontinuity and performance issues due to changes in IP addresses, making it difficult to guarantee service continuity and quality for User Equipment (UE).
Innovation Solution
A method and device for selecting a source IP address based on operator policy, user preference, and application characteristics by receiving and analyzing attribute information for multiple allocated IP addresses, including preference and prohibition information, to determine the most suitable IP address for communication flows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional gateway/network selection techniques are used, then IP address allocation is simplified, but service continuity and quality cannot be guaranteed due to IP address changes
Solution Approach 1:
The system pre-establishes multiple IP addresses and their associated attribute information (operator policy, user preference, application characteristics) before communication occurs. This allows the UE to have a ready pool of IP addresses to choose from, preventing service interruption when network conditions change.
Solution Approach 2:
The IP address selection mechanism is made dynamic by continuously evaluating attribute information and selecting the most appropriate IP address based on current communication requirements. The system can switch between different IP addresses depending on operator policy, user preferences, and application characteristics, ensuring service continuity while adapting to changing conditions.
2Adaptability or versatility
If multiple IP addresses are allocated from different network nodes, then communication flexibility is improved, but IP address changes cause service discontinuity
Solution Approach 1:
The system implements feedback mechanisms where the UE evaluates attribute information about each IP address (including operator policy restrictions, user preferences, and application characteristics) and selects the most appropriate one. This feedback loop ensures that IP address changes are made intelligently to maintain service continuity while preserving communication flexibility across different networks.
Solution Approach 2:
The system changes parameters related to IP address selection by considering multiple attributes (operator policy, user preference, application characteristics) rather than using a fixed selection criterion. This allows the system to adaptively choose the best IP address from multiple allocations, maintaining both flexibility and service continuity.
3Productivity
If IP addresses are selected based on closest network node location, then communication efficiency is improved, but service quality varies for different applications
Solution Approach 1:
The system applies different selection criteria for different applications by evaluating attribute information specific to each application's requirements. Instead of using a single uniform selection rule, the system can prioritize different IP addresses based on whether the application requires low latency, high bandwidth, or specific network policies, thus improving both efficiency and application-specific service quality.

AI summary
The present invention relates to a method and device for setting a selective source IP address. The method for setting a source IP address of a terminal comprises the steps of: receiving an allocation of a plurality of IP addresses from at least one network node; acquiring information on the property of at least one IP address among the plurality of IP addresses; and selecting the source IP address for a flow of the terminal from the plurality of IP addresses on the basis of attribute information of at least one IP address, wherein the attribute information of the IP address can include information on a flow for recommending the use of a corresponding IP address and/or information on a flow for prohibiting the use of the corresponding IP address.
