MHO-Module Handover Mediation for Seamless VoIP in Shared WLANs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current handover technologies in Wireless Local Area Networks (WLANs) and mobile networks do not effectively support seamless communication for present-day WiFi or FMC telephones, particularly in shared WLAN environments, and lack features like tunnel-free relaying and convenience-information correlated commercial communication, which are essential for VoIP and other applications.
Innovation Solution
The 'netsurfing' method enables managed handover between real or virtual home networks and shared WLANs, utilizing a private and operator-controlled MHO-module that provides tunnel-free relaying and convenience-information correlated communication, ensuring legal security, cost reduction, and enhanced user experience by maintaining network openness and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional handover technology is used in WLANs, then handover between access points is possible, but seamless communication for VoIP and FMC telephones is not effectively supported
Solution Approach 1:
The patent introduces an MHO-module as an intermediary component that mediates handover processes between terminal systems and access points. This module implements the MHO-specification to coordinate handover actions, ensuring seamless communication while supporting VoIP and FMC telephones. The MHO-module acts as a controller that manages the handover process, resolving the contradiction by adding a specialized mediation layer.
Solution Approach 2:
The patent changes the operational parameters of handover by implementing a standardized MHO-specification that defines specific procedures and protocols. This specification modifies how handover is executed, enabling seamless communication and broader application support. The parameter changes include standardized message exchanges, handover decision criteria, and coordination protocols between network elements.
2Ease of operation
If tunnel-free relaying is implemented, then network openness is improved, but legal security and operator control are reduced
Solution Approach 1:
The patent implements feedback mechanisms where the MHO-module continuously monitors and reports handover status, terminal system information, and network conditions to operators and network elements. This feedback enables operators to maintain control and legal security while allowing open network access. The feedback loops ensure that tunnel-free relaying operates within controlled parameters, resolving the contradiction between openness and security.
3Productivity
If managed handover with MHO-module is implemented, then handover control and network quality are improved, but system complexity increases
Solution Approach 1:
The patent designs the MHO-module and MHO-specification to be universally applicable across different terminal systems, access points, and network configurations. The standardized specification enables the same handover control mechanisms to work across diverse scenarios, improving productivity without proportionally increasing complexity. The universal design allows existing network elements to be utilized while adding controlled handover management.
4Ease of operation
If convenience-information correlated communication is added, then user experience and commercial opportunities are improved, but communication overhead increases
Solution Approach 1:
The patent implements preliminary action by having the MHO-module exchange convenience-information and commercial messages during the handover process itself, rather than requiring separate communication channels. This approach correlates information exchange with the necessary handover signaling, improving user experience and enabling commercial opportunities without proportionally increasing overall communication overhead. The preliminary exchange of information during mandatory handover signaling optimizes the message quantity.

AI summary
The invention regards a method for providing information to at least one of a first terminal system and a second terminal system, said first terminal system and second terminal system being connected through a network and which are subject to a potential, actual or completed handover process. The method comprises: providing to at least one of the first and the second terminal systems handover-relevant information about the potential, actual or completed handover process, said handover-relevant information including information about potential home/shared integrated access devices (IADs) in a reception area of an IAD of a home network to which the first terminal system is assigned.
