Wireless Data Channel Aggregation for Bandwidth Bottlenecks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for increasing data transmission rates in wireless telecommunications networks, such as connection teaming and PPP Multilink, are limited and do not effectively utilize multiple data channels to enhance bandwidth, especially when transmitting large files or using wireless networks.
Innovation Solution
A device connects to a packet data network through multiple data channels, allowing packets to be transmitted using both channels during a data session, with the ability to vary bandwidth by adding or removing channels, and utilizes PPP Multilink headers for efficient packet fragmentation and reassembly across multiple physical links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If connection teaming is used to increase bandwidth, then the server can connect to the remote device through multiple data links, but the single data link between server and computer creates a bottleneck that limits data transmission speed
Solution Approach 1:
The patent segments the data transmission path into multiple parallel data channels (first data channel and second data channel) between the computer and wireless telecommunications network. Each channel operates independently to transmit packets, eliminating the single-bottleneck limitation of connection teaming and enabling simultaneous data flow through multiple paths.
Solution Approach 2:
The patent merges multiple data channels (voice session and data session) into a unified packet transmission system where both channels work together to transmit data packets. This combination allows the system to aggregate bandwidth from multiple channels while maintaining coordinated packet routing and reassembly at the destination.
2Productivity
If PPP Multilink is used to transmit packets over multiple physical links, then data transmission rate increases, but it is limited to analog data links and requires PPP session establishment
Solution Approach 1:
The patent creates a universal packet transmission method that works across multiple data channel types including wireless telecommunications networks, analog modems, and ISDN connections. The system establishes a single logical data session that can dynamically utilize multiple physical channels regardless of their underlying technology, making the solution adaptable to various network environments without requiring PPP-specific implementations.
Solution Approach 2:
The patent changes the operational parameters by establishing a logical data session rather than requiring PPP sessions, and by using packet fragmentation and reassembly mechanisms that are independent of the underlying physical link type. This allows the system to adapt to different network conditions and channel characteristics while maintaining consistent high-speed transmission performance.
3Device complexity
If a single data channel is used for data transmission, then the system is simpler to manage, but the bandwidth is limited and cannot handle large data exchanges efficiently
Solution Approach 1:
The patent introduces an intermediary packet transmission system that manages multiple data channels through a unified logical data session. The system uses packet fragmentation and reassembly as intermediary processes to coordinate data flow across multiple channels, providing simple management interfaces while delivering aggregated bandwidth benefits. The intermediary layer handles channel coordination, packet routing, and reassembly transparently.

AI summary
A device can connect to a packet data network through a first data channel, such as a connection with a wireless telecommunications network. The device can additionally connect to the packet data network through a second data channel. The device can simultaneously transmit data over the first and second data channels. Data channels can be added or removed in order to change the bandwidth available to the device.
