Context-Aware CBRS Profile Selection for Faster Network Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in wireless communication is the slow and inefficient process of selecting the right Citizens Broadband Radio Service (CBRS) profile for network access, which can take seconds or minutes, leading to poor connections and increased power consumption, especially when switching between primary cellular data networks and CBRS networks.
Innovation Solution
A dynamic dual standby mode is implemented in user devices, allowing them to activate data on both primary cellular data networks and CBRS networks, with a profile selection system using contextual information to quickly choose the appropriate CBRS profile based on location, congestion, and time, minimizing the need for time-consuming modem scans.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the user device scans available CBRS frequency bands using the modem to determine network availability and select the right profile, then the device can ensure accurate network selection, but the process takes seconds to minutes leading to slow connection establishment and increased power consumption
Solution Approach 1:
The system pre-determines CBRS network availability and selects the appropriate profile before the modem scan is completed. The processor identifies available CBRS networks and selects the correct profile in advance, based on contextual information such as location, time, and network conditions, so that when the modem scan finishes, the device is already configured to connect immediately.
Solution Approach 2:
The processor acts as an intermediary between the modem scan results and the profile selection process. Instead of waiting for the modem to complete its scan and then selecting a profile, the processor independently determines network availability and selects profiles based on contextual data, mediating the connection process to eliminate waiting time.
2Reliability
If the user device performs a modem scan to determine CBRS network availability and profile selection, then the device can ensure reliable network connection, but the scanning process increases power consumption
Solution Approach 1:
The system performs only the necessary portion of the network selection process before the modem scan completes. The processor determines network availability and selects profiles based on contextual information without waiting for the full modem scan, performing partial action that is sufficient for reliable connection while avoiding the energy cost of completing the entire scan process.
Solution Approach 2:
The device performs preliminary network availability determination and profile selection based on contextual information before the modem scan completes, reducing the need for extensive scanning and thereby lowering power consumption while maintaining connection reliability.
3Adaptability or versatility
If multiple CBRS profiles are stored on the user device or remote service for access to various CBRS networks, then the device can access multiple networks in the region, but the complexity of selecting the right profile increases
Solution Approach 1:
The system uses contextual information such as location, time, and network conditions as feedback to automatically select the appropriate CBRS profile from multiple stored profiles. The processor analyzes this feedback data to determine which profile is most suitable for current conditions, eliminating the need for manual selection and reducing complexity.
Solution Approach 2:
The device automatically selects the appropriate CBRS profile based on contextual information without requiring user intervention. The processor independently evaluates available profiles and selects the most suitable one based on current network conditions, location, and time, making the system self-service and reducing operational complexity.
4Adaptability or versatility
If the protocol modem connects to CBRS network or primary cellular data network, then the modem can utilize the same protocol for both networks, but the modem cannot connect to multiple networks concurrently
Solution Approach 1:
The system performs preliminary determination of CBRS network availability and profile selection before the modem needs to switch networks. By identifying the target network and selecting the appropriate profile in advance based on contextual information, the device prepares for network switching beforehand, enabling faster transition when the modem is ready to connect.
