Peer-to-Peer CDN Data Sharing for Offline Mobile Network Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication devices face issues with unreliable and expired network data, particularly in satellite or non-terrestrial networks, due to deviations between projected and actual network characteristics, which can lead to inaccessible networks and data unavailability.
Innovation Solution
Mobile communication devices utilize peer-to-peer (P2P) networks to share Content Delivery Network (CDN) data with other devices, transmitting beacon signals to request and receive updated network data when conventional networks are unavailable, using criteria such as data age, battery health, and emergency situations to determine transmission frequency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mobile communication devices periodically refresh CDN data to maintain reliability, then network data reliability is improved, but energy consumption increases and data availability is reduced during refresh periods
Solution Approach 1:
The patent combines multiple devices into a peer-to-peer network where CDN data is shared collectively. Instead of each device independently refreshing data from the satellite network (consuming energy), devices share cached data through direct peer-to-peer communication, maintaining reliability while reducing individual energy consumption.
Solution Approach 2:
The patent implements preliminary action by having devices cache CDN data in advance when network conditions permit. Devices store projected network characteristics and satellite ephemeris data before they expire, so that when network access is unavailable or energy is constrained, reliable data is already available locally or can be obtained from peer devices.
2Loss of information
If mobile communication devices transmit beacon signals frequently to request updated CDN data, then network data availability is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic action by transmitting beacon signals at optimized intervals rather than continuously. Devices monitor their CDN data age and transmit beacon signals only when data approaches expiration or when triggered by specific events, balancing data availability needs with energy conservation in peer-to-peer communication.
3Use of energy by moving object
If mobile communication devices store CDN data for extended periods to reduce refresh frequency, then energy consumption is reduced, but data reliability deteriorates due to expiration
Solution Approach 1:
The patent implements feedback mechanisms where devices monitor the age and reliability of their cached CDN data. When data approaches expiration or when beacon signals indicate updated data is available from peers, devices automatically initiate data refresh operations, ensuring reliability is maintained without excessive energy consumption from continuous monitoring.
4Loss of information
If mobile communication devices use peer-to-peer networks to share CDN data, then data availability in remote locations is improved, but device complexity increases
Solution Approach 1:
The patent implements universality by designing peer-to-peer communication mechanisms that leverage existing device capabilities. The same transceiver and processing circuitry used for standard cellular and Wi-Fi communications are utilized for peer-to-peer CDN data sharing, avoiding the need for specialized hardware and minimizing additional device complexity while improving data availability in remote locations.

AI summary
A mobile communication device is configured to receive updated network data, such as updated Content Delivery Network (CDN) data utilized to access a first network, without accessing the first network and a second network, such as a Wi-Fi or cellular network. The mobile communication device periodically transmits, via a peer-to-peer (P2P) network, a beacon signal indicating a network data request for the updated network data. A rate at which the mobile communication device periodically transmits the beacon signal is based on various criteria, such as an origination date of network data stored on the mobile communication device, an amount of time between the origination date and the present date, a battery health of the mobile communication device, and/or various inputs to the mobile communication device. An additional mobile communication device receives the beacon signal and transmits the updated network data to the mobile communication device.
