Miracast Source Relay for Sink Network Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computing devices with limited network connectivity, such as those supporting only peer-to-peer wireless connections, are unable to access external networks like the Internet, limiting their functionality and preventing software updates or communication with network services.
Innovation Solution
Establishing a secondary data channel over a peer-to-peer wireless network connection between a computing device with Internet access and one without, allowing the latter to relay or proxy requests to external networks, enabling access to network services while maintaining separate data channels for primary functions like audio-video streaming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a computing device supports only peer-to-peer wireless connections for cost and simplicity, then device cost and structural simplicity are improved, but network service access capability deteriorates
Solution Approach 1:
The patent introduces a gateway device as an intermediary between the peer-to-peer wireless network and external networks. The gateway receives data from devices with limited connectivity and forwards it to external networks, enabling network service access without requiring the end devices to have direct network connectivity. This resolves the contradiction by maintaining device simplicity while providing network access through the gateway mediator.
2Device complexity
If a single data channel is used for peer-to-peer communication, then channel simplicity is improved, but functionality for both streaming and network access deteriorates
Solution Approach 1:
The patent segments the data communication into two separate channels: a primary data channel for peer-to-peer audio-video streaming and a secondary data channel for network service access. This segmentation allows each channel to be optimized for its specific function while both coexist over the same wireless connection, resolving the contradiction between channel simplicity and functional versatility.
3Adaptability or versatility
If network service access is added to peer-to-peer devices, then network service accessibility is improved, but interference with primary streaming function deteriorates
Solution Approach 1:
By segmenting data traffic into separate primary and secondary channels, the patent ensures that network service communications do not interfere with the primary audio-video streaming function. Each channel operates independently with dedicated resources, maintaining streaming reliability while enabling network access.
Solution Approach 2:
The patent maintains continuous, uninterrupted audio-video streaming over the primary channel while simultaneously enabling network service access over the secondary channel. The separation ensures that the continuous streaming action is not disrupted by network service data transmissions, preserving both functions simultaneously.
Data Source
AI summary
Techniques are described for providing and accessing network services via a peer-to-peer wireless network connection which is established between a first computing device and a second computing device. The first computing device has an additional network connection that allows it to access network services via external networks (e.g., the internet). The second computing device is only connected to the peer-to-peer wireless network connection and has no Internet access. A primary data channel is established between the first and second computing devices over the peer-to-peer wireless network connection (e.g., for streaming audio and/or video content). A secondary data channel is negotiated between the first computing device and the second computing device. The secondary data channel is used by the second computing device to access the network services via the first computing device which performs relay and/or proxy operations for the second computing device.
