Private Network Channel Aggregation Across CBRS and WLAN Bands
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cellular and WLAN access point devices require separate management and channel allocation, lacking a unified solution for integrating licensed and unlicensed frequency bands to meet Quality of Service (QoS) requirements.
Innovation Solution
A single network management platform aggregates both licensed and unlicensed frequency bands, using a channel allocation device to select and manage CBRS and non-CBRS frequency bands, along with WLAN channels, to meet specific QoS demands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate management is used for cellular and WLAN access point devices, then device complexity is reduced and management is simplified, but channel allocation cannot be optimized based on unified QoS requirements
Solution Approach 1:
The patent merges cellular and WLAN access point device management into a single unified management system. The management device receives channel requirement information from both cellular and WLAN access point devices, aggregates their channel allocation requests, and coordinates channel assignments across both technology types to meet unified QoS requirements, thereby resolving the contradiction between management simplicity and allocation optimization
2Reliability
If licensed and unlicensed frequency bands are managed separately, then regulatory compliance is simplified, but network performance is reduced due to inability to aggregate channels based on QoS requirements
Solution Approach 1:
The patent segments the frequency spectrum into licensed and unlicensed bands while maintaining separate regulatory compliance frameworks for each. The management device processes channel allocation requests for both licensed and unlicensed bands according to their respective regulatory requirements, then aggregates selected channels from both segments to meet QoS requirements, thereby achieving both compliance and performance optimization
Solution Approach 2:
The management device performs multiple functions: it manages licensed and unlicensed frequency bands separately for regulatory compliance, aggregates channel allocation requests from both bands, coordinates channel assignments to meet QoS requirements, and transmits channel aggregation information to access point devices. This multi-functionality resolves the contradiction between compliance simplicity and network performance

AI summary
A method of operating a private network includes obtaining channel requirement information indicating a bandwidth of a channel, obtaining available channel information indicating Citizens Broadband Radio Service (CBRS) frequency bands and non-CBRS frequency bands available to be allocated to the channel, selecting one or more of the CBRS frequency bands and one or more of first non-CBRS frequency bands based on the channel requirement information, generating channel aggregation information indicating the selected CBRS and non-CBRS frequency bands, generating transmission power level information for the selected CBRS and non-CBRS frequency bands, transmitting the channel aggregation information and the transmission power level information, receiving the first channel aggregation information and the first transmission power level information at an access point device, and transmitting data in the channel using the selected CBRS and non-CBRS frequency bands from the access point device based on the first transmission power level information.
