Solution Overview
Problem
As the number of users connecting to a WiFi Access Point increases, the probability of data collision rises, wasting wireless radio resources and reducing data throughput, thus necessitating a solution to enhance system data throughput and service quality.
Innovation Solution
A wireless communication device with a first and second wireless transceiving interface, where the first interface is adapted to a more reliable network architecture (e.g., LTE) and the second to a less reliable one (e.g., WiFi, with a resource allocation controller that selectively transceives data through either interface based on connection status information to improve reliability and reduce collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple users connect to the same WiFi Access Point, then network coverage and accessibility are improved, but data collision probability increases and data throughput decreases
Solution Approach 1:
The patent segments the network communication path into two independent interfaces: a primary WiFi interface for data transmission and a secondary cellular interface for control signaling. This segmentation allows control messages to travel through a dedicated, collision-free channel while data flows through the shared WiFi medium, resolving the throughput degradation caused by multiple users accessing the same AP.
Solution Approach 2:
The patent introduces a cellular network interface as an intermediary channel for transmitting control information between the wireless communication device and the network. This intermediary prevents control signaling from competing with data traffic on the WiFi interface, eliminating collisions and maintaining high throughput even as network accessibility increases.
2Adaptability or versatility
If WiFi network capacity is increased to support more users, then service coverage is improved, but connection reliability deteriorates due to data collisions
Solution Approach 1:
The communication system is segmented into data transmission (WiFi interface) and control signaling (cellular interface) channels. This segmentation ensures that control messages, which require high reliability, are transmitted through a dedicated cellular channel that is not subject to WiFi collisions, thereby maintaining connection reliability as network capacity scales.
Solution Approach 2:
The patent changes the transmission medium parameter for control signaling from WiFi (shared, collision-prone) to cellular (dedicated, reliable). This parameter change in the communication channel ensures that control information maintains high reliability even as the WiFi network capacity increases to support more users.
3Device complexity
If a single wireless interface is used for both control and data transmission, then device complexity is reduced, but resource allocation efficiency deteriorates
Solution Approach 1:
The wireless communication device is designed with multi-functionality, incorporating both WiFi and cellular interfaces. The WiFi interface handles data transmission while the cellular interface handles control signaling, allowing the device to optimize resource allocation by directing different types of traffic through appropriate channels, thereby improving overall resource allocation efficiency despite increased device complexity.

AI summary
A wireless communication device includes a first wireless transceiving interface, a second wireless transceiving interface and a resource allocation controller. The first wireless transceiving interface is adapted to a first network architecture. The second wireless transceiving interface is adapted to a second network architecture, wherein a connection scheme of the first network architecture is more reliable than that of the second network architecture. The resource allocation controller transceives data related to the second wireless transceiving interface selectively through the first wireless transceiving interface or the second wireless transceiving interface according to a connection status information associated with the second wireless transceiving interface.
