Small-Cell Wireless Traffic Prioritization With CPE Traffic Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing small-cell wireless networks fail to differentiate and prioritize data traffic for individual client devices connected to Customer Premises Equipment (CPE), leading to inefficient use of radio frequency resources and suboptimal quality of experience for users.
Innovation Solution
Implementing a system that generates a traffic profile message for each client device connected to CPE, allowing the base station to prioritize data traffic based on type and allocate resources accordingly, using CBRS compliant CBSDs and 3GPP 4G/5G technology to enhance data delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If small-cell wireless networks treat all data traffic equally without differentiation, then device complexity is reduced and ease of operation is improved, but resource utilization efficiency deteriorates and quality of experience worsens
Solution Approach 1:
The patent segments data traffic into different types (e.g., latency-sensitive, latency-tolerant, background traffic) and creates separate priority queues for each type. This allows the network to differentiate and prioritize traffic without requiring complex per-packet analysis, as segmentation occurs at the flow level based on traffic type identification.
Solution Approach 2:
The patent implements preliminary classification of data traffic into priority queues before transmission. By pre-categorizing traffic types and assigning them to appropriate queues based on their characteristics (latency requirements, bandwidth needs), the system prepares traffic for efficient scheduling without requiring complex real-time decision-making during transmission.
2Measurement precision
If small-cell wireless networks implement per-client traffic prioritization, then quality of experience is improved and resource allocation efficiency is enhanced, but measurement precision requirements increase and detection difficulty worsens
Solution Approach 1:
The patent introduces an intermediary traffic classification mechanism that sits between the client devices and the radio resource management system. This intermediary identifies traffic types based on observable characteristics (protocol type, port numbers, packet patterns) and assigns them to priority queues, thereby reducing the measurement precision requirements for the base station while maintaining accurate traffic differentiation.
3Productivity
If small-cell wireless networks allocate radio frequency resources dynamically based on traffic type, then resource allocation efficiency is improved and productivity increases, but device complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent implements dynamic resource allocation where the scheduler adjusts radio frequency resource distribution based on real-time traffic conditions and priority queue states. The system continuously monitors queue lengths, traffic types, and channel conditions to dynamically allocate resources, allowing high-priority traffic to receive more resources when needed while maintaining simplicity through automated scheduling algorithms.
Solution Approach 2:
The patent incorporates feedback mechanisms where the scheduler monitors the outcomes of resource allocation decisions and adjusts future allocations accordingly. By tracking which priority queues are underutilized or overloaded, the system automatically rebalances resource distribution without requiring manual reconfiguration, thereby maintaining ease of operation while improving data service efficiency.
Data Source
AI summary
Methods and apparatus for prioritizing data traffic in small-cell wireless system. In one embodiment, the system utilizes “quasi-licensed” CBRS (Citizens Broadband Radio Service) wireless spectrum in conjunction with a wireless communication network (e.g., 3GPP 4G-LTE or 5G-NR-based). A “traffic profile” message is used to prioritize the data traffic. In one variant, the traffic profile message is generated by a Customer Premises Equipment (CPE) such as a CBRS FWA, and includes data related to CPE identification, default bearer identification, number of client devices served by the CPE (e.g., via a wireless router connected to the CPE), traffic type and/or priority level associated with each client device and/or data traffic type, etc. In another variant, the base station provides data services to a plurality of fixed wireless access (FWA) apparatus installed at user or subscriber premises of a network based on prioritization according to the present disclosure.
