IP Pool Name Lists for Service-Based Address Assignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 4G networks, such as LTE, network devices like PDN Gateways face challenges in determining the appropriate IP address pool for assignment based on the type of service and user characteristics during user equipment connections, leading to inefficient IP address management.
Innovation Solution
Implementing IP address pool name lists that include prioritized IPv4 and IPv6 address pools, allowing network devices to select suitable IP addresses for user equipment based on service types and user characteristics, with mechanisms to handle default assignments or rejection of connections if suitable pools are unavailable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If network devices use traditional IP address pool assignment methods, then the system is simple to operate, but the IP address management efficiency is poor and cannot properly accommodate different service types and user characteristics
Solution Approach 1:
The invention segments the IP address pools into multiple named pools (e.g., IPv4 pool, IPv6 pool, dedicated pool) and organizes them in a structured list format. Each pool can be independently selected based on service type and user characteristics, enabling efficient IP address management while maintaining clear organizational structure.
Solution Approach 2:
The network device pre-configures and stores multiple IP address pool name lists in advance, organized by service types and user characteristics. When a user device attaches to the network, the appropriate pool is already prepared and can be selected immediately, improving assignment efficiency without requiring complex real-time decisions.
2Measurement precision
If network devices implement prioritized IP address pool selection based on service types, then IP address assignment accuracy improves, but the decision-making complexity increases
Solution Approach 1:
The invention applies different selection criteria to different IP address pools based on their specific characteristics and associated service types. Each pool has defined qualities (IPv4, IPv6, dedicated) that match specific user requirements, enabling accurate assignment while using simple matching logic rather than complex algorithms.
Solution Approach 2:
The patent introduces named pool identifiers as intermediaries between the user device attachment information and the actual IP address pools. These names serve as mediators that simplify the matching process, allowing network devices to select appropriate pools based on service type and user characteristics without complex decision-making logic.
3Reliability
If the system provides fallback mechanisms for unavailable IP pools, then connection reliability improves, but the system complexity increases
Solution Approach 1:
The invention implements fallback mechanisms that are pre-configured in the network device. When a specific IP address pool is unavailable, the system can automatically switch to alternative pools or use default assignment rules that are already prepared, ensuring continuous service without requiring complex real-time fallback decisions.

AI summary
A method including receiving a session request associated with a user equipment (UE); selecting one or more network address pool name lists based on a type of service to be provided to the UE; selecting one or more network address pool names from the one or more network address pool name lists based on a priority associated with the one or more network address pool names; selecting one or more network addresses from the one or more network address pool names; assigning the one or more network addresses to the UE; and establishing a session with the UE.
