Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication technologies face challenges in maintaining Internet Protocol (IP) session persistence when transitioning from macro to access point networks, leading to dropped calls, interrupted data downloads, and poor user experience due to gaps in wireless coverage.
Innovation Solution
Implementing IP session persistence by duplicating and transmitting IP data content over multiple base stations, including macro and access point base stations, with sequencing and quality metrics to ensure seamless data compilation and playback on mobile devices, even in areas with poor coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If IP data content is transmitted over multiple base stations with duplication and sequencing, then session persistence and service continuity are improved, but device complexity and network complexity increase
Solution Approach 1:
The patent segments IP data content into multiple sequences and transmits them through different base stations (macro and access point). Each base station handles specific sequence ranges, allowing the mobile device to reconstruct the complete data set by collecting packets from multiple sources. This segmentation enables session persistence during network transitions without requiring complex end-to-end duplication management.
Solution Approach 2:
The patent introduces an intermediary mechanism where the network infrastructure (base stations and controlling entities) manages the duplication and sequencing of IP packets. Rather than requiring complex device-side implementation, the network intermediaries handle the complexity of maintaining multiple transmission paths and ensuring data completeness, thus improving reliability while managing complexity at the network layer.
2Area of stationary object
If additional access point base stations are deployed to cover dead spots, then wireless coverage and service availability are improved, but network complexity and infrastructure cost increase
Solution Approach 1:
The patent divides the network coverage area into macro base station zones and access point base station zones. Each type of base station serves specific geographic segments, with access points filling in dead spots and macro stations providing broad coverage. This segmentation allows incremental deployment to extend coverage without requiring complete network redesign.
Solution Approach 2:
The patent creates a universal network architecture where both macro base stations and access point base stations can serve the same IP sessions simultaneously. The system is designed to work with heterogeneous base station types, allowing existing infrastructure to be leveraged while adding new access points for coverage extension, thus improving area coverage without proportionally increasing overall system complexity.
3Duration of action of moving object
If IP packets are duplicated and transmitted through multiple base stations, then service continuity during network transitions is improved, but data transmission efficiency and network bandwidth utilization deteriorate
Solution Approach 1:
The patent implements partial duplication where not all IP packets are transmitted through all base stations. Instead, the system duplicates only necessary packets for sessions at risk of interruption during transitions, and uses sequencing to manage the partial redundancy. This approach maintains session continuity for critical periods while avoiding excessive bandwidth consumption for entire data sets.
Solution Approach 2:
The patent applies preliminary action by pre-establishing multiple transmission paths and pre-sequencing IP packets before network transitions occur. The system prepares duplicate transmission channels in advance for sessions that may be interrupted, rather than reacting after service disruption. This allows efficient use of bandwidth by only activating duplication when needed for session persistence.

AI summary
Providing for mobile communications incorporating Internet Protocol (IP) persistence is described herein. By way of example, IP persistence can be implemented for a mobile device receiving IP data content over a mobile network. Particularly, if the mobile device encounters a region of poor wireless coverage, the IP data content can be transmitted to the mobile device over a plurality of base stations concurrently. Thus, the IP persistence can comprise duplicating the IP data content and transmitting separate independent wireless transmissions of the content to the mobile device from separate cells or separate transmitters. The duplicate transmitting can be continued while the mobile device is within the region of poor wireless coverage, until a suitable quality of service or quality of experience parameter is met for a serving network, or the like.
