Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If channel bonding is applied to combine different channels to increase bandwidth, then the bandwidth capacity is improved, but the device complexity increases due to requiring multipath control entities and coordination between multiple network technologies
Solution Approach 1:
The patent introduces a multipath control entity as an intermediary component that manages and coordinates multiple network technologies (wired and wireless). This entity handles the complexity of channel bonding by centralizing control functions, including determining available network technologies, making split decisions for data streams, and managing multipath connections. This intermediary approach resolves the contradiction by encapsulating the complexity in a dedicated control entity while providing simplified interfaces to end devices and application servers.
2Adaptability or versatility
If channel bonding combines channels from different physical access technologies, then the versatility and adaptability are improved, but the difficulty of detecting and measuring available technologies increases
Solution Approach 1:
The multipath control entity is designed with multi-functional capabilities to handle diverse network technologies (wired, wireless, different radio access networks). It performs multiple functions including technology detection, availability determination, split decision-making, and connection management. This universal design enables the system to work with various physical access technologies without requiring separate specialized mechanisms for each technology, thus improving versatility while managing detection complexity through a unified approach.
3Ease of operation
If transparent multipath transmission is implemented without changing application servers or client apps, then the ease of operation is improved, but the device complexity increases due to requiring proxy and multipath connection modules
Solution Approach 1:
The patent introduces a proxy as an intermediary component positioned between the application server and the multipath control entity. This proxy handles the complexity of multipath transmission by managing data plane streams, coordinating with multipath connection modules, and abstracting the underlying multi-technology complexity from applications. The transparency to applications is achieved because the proxy and multipath modules handle all complexity internally, requiring no changes to application servers or client apps while maintaining ease of operation.
4Loss of time
If existing access technologies are used without increasing spectrum allocation, then the loss of time for spectrum allocation is avoided, but the productivity decreases due to bandwidth limitations
Solution Approach 1:
The patent implements channel bonding by merging multiple existing network technology channels (wired and wireless, different radio access networks) into a unified high-capacity data transmission path. Instead of allocating new spectrum or deploying new infrastructure, the system combines available channels from existing technologies to achieve higher aggregate bandwidth. This merging approach avoids the time-consuming spectrum allocation process while significantly improving data transmission capacity and productivity by utilizing the sum of available channel bandwidths.
Data Source
AI summary
A method, by a multipath control entity, to control a transmission of a user data plane stream between a mobile entity and a proxy, wherein the user data plane stream is exchanged between the mobile entity and an application server connected to the proxy. In a split decision, it is determined that the user data plane stream is split into at least two stream parts and over which of the supported network technologies each of the at least two stream parts is transmitted between the mobile entity and proxy. A multipath connection module in the mobile entity is informed in a first control message which stream part is transmitted by which network technology in accordance with the split decision, and a multipath connection module provided in the proxy is informed in a second control message which stream part is transmitted by which network technology in accordance with the split decision.
