Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cellular communication systems face bandwidth constraints due to limited licensed spectrum, especially with increasing data traffic, and existing solutions for utilizing unlicensed bands are not efficient for non-operator devices to access quality-assured services.
Innovation Solution
A system that allows non-operator devices to securely pair with operator devices via local connections like Bluetooth or Wi-Fi, enabling access to supplementary downlink channels through carrier aggregation with primary and control channels in unlicensed frequency bands, facilitating quality-of-service assured data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If licensed spectrum bands are used for cellular data transmission, then service quality and reliability are improved, but available bandwidth is limited and spectrum resources become constrained
Solution Approach 1:
The patent combines licensed and unlicensed spectrum bands through carrier aggregation, merging the reliability benefits of licensed bands with the bandwidth capacity of unlicensed bands to simultaneously improve service quality and increase available bandwidth
Solution Approach 2:
The system enables unlicensed bands to serve dual purposes: traditional Wi-Fi communications and cellular data transmission, allowing the same spectrum resource to fulfill multiple functions and increase overall bandwidth availability
2Quantity of substance
If unlicensed bands are utilized for cellular data traffic, then available spectrum resources are increased, but non-operator devices cannot efficiently access quality-assured services
Solution Approach 1:
The operator device acts as an intermediary between non-operator devices and the cellular network, establishing local connections with non-operator devices and relaying data through the supplementary downlink channel, thereby enabling efficient access for devices that cannot directly access the cellular network
Solution Approach 2:
The system segments the downlink channel into a primary downlink channel for operator devices and a supplementary downlink channel for non-operator devices, allowing each segment to be optimized for its specific access requirements and improving overall access efficiency
3Ease of operation
If non-operator devices directly access primary downlink or control channels, then access to cellular services is enabled, but system complexity and interference increase
Solution Approach 1:
The downlink channel is segmented into primary and supplementary components, with the supplementary downlink channel specifically designated for non-operator devices. This segmentation allows non-operator devices to access cellular services through a dedicated channel without complicating the primary channel access mechanisms
Solution Approach 2:
The supplementary downlink channel extracts and isolates the specific requirements of non-operator device access from the main cellular network infrastructure, allowing these devices to receive services without directly accessing or interfering with the primary control and downlink channels

AI summary
A device for providing downlink channel access for non-operator devices includes at least one processor that is configured to establish a local connection with an operator device that is serviced by a network operator. The at least one processor is configured to provide, to the operator device over the local connection, a request to establish a connection to a network, the request comprising a destination address. The at least one processor is configured to receive, from the operator device over the local connection, control information for reception of a downlink channel provisioned by the network operator for the operator device. The at least one processor is configured to receive downlink data associated with the destination address on the downlink channel.
