IP Address Delegation via Core Network Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless networks face challenges in efficiently managing and authorizing IP address allocation to devices connected through User Equipment (UE) and Fixed Wireless Access (FWA) devices, leading to potential IP address shortages and mismanagement.
Innovation Solution
A core network-based authorization verification procedure is implemented to dynamically manage and allocate IP addresses, allowing UE to request and delegate IP address pools based on authorization, using AI/ML for proactive allocation and tracking available IP addresses to prevent over-allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If IP addresses are allocated statically or without dynamic authorization verification, then the allocation process is simple, but IP address shortages occur and management efficiency deteriorates
Solution Approach 1:
The patent implements dynamic IP address allocation where the network dynamically adjusts IP address assignment based on real-time authorization verification results and network conditions. The system transitions from static pre-configuration to dynamic on-demand allocation, allowing IP addresses to be granted, revoked, or modified based on current user needs and network capacity, thereby improving allocation efficiency and preventing shortages.
Solution Approach 2:
The patent establishes a feedback mechanism where the network continuously monitors IP address usage, authorization status, and allocation effectiveness. Based on this feedback, the system adjusts future allocation decisions, verifies authorizations proactively, and optimizes the distribution of IP addresses to prevent both shortages and mismanagement while maintaining efficient utilization.
2Productivity
If IP addresses are allocated without proactive authorization verification, then the allocation process is faster, but network security and stability deteriorate
Solution Approach 1:
The patent implements preliminary authorization verification before IP addresses are allocated to user equipment. The network proactively checks authorization credentials, validates user entitlements, and verifies network policies before granting IP address assignment. This preliminary action ensures security and stability are maintained while enabling relatively fast allocation by preventing rejections later in the process.
Solution Approach 2:
The patent replaces manual or reactive authorization verification with an automated electronic verification system. The network uses automated authentication protocols, digital credentials, and electronic policy enforcement mechanisms to verify authorizations rapidly and securely, substituting mechanical or manual processes with automated systems that maintain both speed and security.
3Device complexity
If IP address pools are not tracked and monitored, then the management system is simpler, but IP address mismanagement and over-allocation occur
Solution Approach 1:
The patent implements a self-service tracking system where the network automatically monitors IP address pool status, usage patterns, and allocation states without requiring external intervention. The system self-updates authorization records, tracks available versus allocated addresses, and autonomously enforces allocation policies, providing accurate management while keeping the overall system architecture relatively simple through automation rather than complex manual procedures.

AI summary
A system described herein, such as an Session Management Function (“SMF”) of a core network of a wireless network, may receive a request to associate a particular User Equipment (“UE”) with a plurality of Internet Protocol (“IP”) addresses. The UE may be associated with a communication session between the UE and the core network. The system may output an information request for IP address authorization information from a UE information repository associated with the wireless network, and may receive a response to the information request from the UE information repository. The system may identify a quantity of IP addresses based on the response to the information request, and may provide the identified quantity of IP addresses to the particular UE in response to the request to associate the particular UE with the plurality of IP addresses.
