Neutral-Host Network Redirection to MNO
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, handover from a neutral-host network to a mobile network operator (MNO) network is unsupported due to their separate nature, necessitating a method to redirect user equipment (UE) from a neutral-host network to its associated MNO network.
Innovation Solution
A method and system for determining information about MNO networks and sending redirection messages to UE, allowing seamless handover by identifying and selecting the appropriate MNO network based on received PLMN IDs, handover information, measurement reports, and OAM configuration files, and sending redirection messages to UE to facilitate connection to the correct MNO network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If handover is supported between neutral-host network and MNO network, then communication continuity is improved, but network complexity increases due to integration requirements
Solution Approach 1:
The patent introduces a redirection mechanism as an intermediary solution between the neutral-host network and MNO network. Instead of implementing full handover support which would require complex integration, the system uses redirection messages that guide UEs to connect to appropriate MNO networks, thereby maintaining communication continuity without the complexity of direct handover integration.
Solution Approach 2:
Rather than attempting to enable handover from MNO network to neutral-host network (the conventional approach), the patent inverts the approach by enabling redirection from neutral-host network to MNO network. This reversal simplifies the architecture by allowing the neutral-host network to act as a temporary access point that redirects traffic to the appropriate MNO network infrastructure.
2Measurement precision
If redirection information is collected from multiple sources, then redirection accuracy is improved, but information processing complexity increases
Solution Approach 1:
The patent segments the information collection process into distinct sources (UE measurements, OAM configuration files, handover information) and processes each source independently. The wireless access point maintains separate data structures for each information type and applies specific processing rules for each source, thereby improving redirection accuracy through comprehensive data collection while managing complexity through modular processing approaches.
Data Source
AI summary
A method for redirecting a user equipment (UE) from a first network to a second network is described. The method includes determining, at a wireless access point of the first network, information for the UE about one or more mobile network operator (MNO) networks. The method also includes selecting the second network for redirection from among the one or more MNO networks based on the determined information. The method further includes sending the UE a redirection message that redirects the UE from the first network to the second network.
