Proxy Device Throttling Uplink Data Priorities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cellular wireless communication systems, a device may face challenges in transmitting data to a radio access network (RAN) due to inadequate signal strength, necessitating a method to manage resource allocation for data transmission when acting as a proxy for another device, ensuring prioritization of its own data over received data.
Innovation Solution
A first subscriber device manages resource allocation by applying a different transmission priority for its own generated data compared to data received from a second subscriber device, using a local communication link to facilitate data transmission to the RAN, with higher priority given to its own data when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a device acts as a proxy to transmit data from a second device to the RAN, then connectivity is enabled for the second device, but resource allocation conflicts arise between the proxy's own data and the second device's data
Solution Approach 1:
The patent applies local quality by assigning different transmission priorities to different data sources at the proxy device. Specifically, data generated by the first device (proxy) is assigned a first transmission priority, while data received from the second device is assigned a second transmission priority. This differentiation in priority levels allows the proxy to manage its own data and the second device's data with distinct quality of service characteristics, resolving the resource allocation conflict while maintaining connectivity for both devices.
2Reliability
If the first device prioritizes its own data transmission, then its own communication quality is improved, but the second device's data transmission may be delayed or throttled
Solution Approach 1:
The patent implements dynamic resource allocation through a throttling mechanism that adjusts the transmission rate of the second device's data based on available resources and priority levels. The proxy device dynamically controls the data flow from the second device, applying throttling when necessary to ensure that the first device's own data transmission requirements are met, while still allowing the second device's data to be transmitted at a controlled rate. This dynamic approach balances communication quality for the proxy device with timely data transmission for the second device.
3Productivity
If the proxy device transmits both its own data and received data with equal priority, then resource utilization is maximized, but the proxy's own communication requirements may not be satisfied
Solution Approach 1:
The patent applies segmentation by dividing the data transmission streams into distinct priority categories. Data generated by the first device is segmented into a high-priority stream, while data received from the second device is segmented into a lower-priority stream. This segmentation allows the proxy device to allocate resources preferentially to its own communication requirements while still utilizing available resources to transmit the second device's data, thereby satisfying the proxy's communication requirements while maintaining reasonable resource utilization.
Data Source
AI summary
A method and system for managing the allocation of uplink transmission resources. A first subscriber device may communicate with a second subscriber device over a local communication link. The first subscriber device may also transmit data over an air interface to a radio access network (RAN) serving the first subscriber device, with the first subscriber device serving as a proxy between the second subscriber device and the RAN. In response to the data including first data originated by the first subscriber device and second data originated by the second subscriber device that is received by the first subscriber device from the second subscriber device over the local communication link, the first subscriber device may be arranged to apply a different transmission priority for the transmitting of the first data over the air interface than for the transmitting of the second data over the air interface.
