Cell Quality Data Query for Abnormal Cell Handover Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for selecting cells with 'best signal quality' for network connection often result in network connection failures, as they fail to identify abnormal cells, leading to inefficient Internet access.
Innovation Solution
An electronic device obtains target location or travel information to trigger a request for cell quality data from a network device, which generates and provides data based on the transmission quality of multiple devices in the new block, enabling the device to connect to optimal cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic device connects to a cell with best signal quality selected by ISP, then the current Internet access quality is optimized, but the device may fail to access Internet normally due to abnormal cells
Solution Approach 1:
The patent applies preliminary action by having the electronic device proactively query cell quality data from the network device before attempting to connect to a cell. The device obtains location information, determines the corresponding block, and queries cell quality data in advance, allowing it to identify and avoid abnormal cells before connection attempts, thereby preventing network connection failures.
Solution Approach 2:
The patent implements feedback by establishing a closed-loop system where the electronic device queries cell quality data from the network device, uses this feedback information to evaluate cell suitability, and adjusts its connection decisions accordingly. The network device provides real-time cell quality feedback based on multiple data sources including signal strength, transmission quality, and abnormal cell information from other devices.
2Reliability
If the device queries cell quality data in real-time before connection, then network connection failure is avoided, but additional network communication overhead is introduced
Solution Approach 1:
The patent minimizes communication overhead by performing cell quality queries only when necessary - specifically when the device's location changes to a new block or when entering a flight mode. This preliminary action approach avoids continuous querying while still ensuring reliable connection by checking cell quality before connection attempts in relevant scenarios.
Solution Approach 2:
The patent applies partial action by selectively querying cell quality data only in specific scenarios (location change, flight mode entry) rather than continuously. This partial querying approach balances the need for reliable connection information with the goal of minimizing network communication overhead and time loss.

AI summary
This application discloses a cell data transmission method and apparatus and an electronic device. The method includes: obtaining, by an electronic device, target information, where the target information is at least one of the following: target location information or target travel information, where the target location information is used to indicate a current geographical location of the electronic device, and the target travel information is used to indicate a travel of a user of the electronic device; when the target information indicates block handover of the electronic device from a first block to a second block, sending, by the electronic device, a request message to a network device, where the request message is used to request the network device to deliver cell quality data; and receiving, by the electronic device, the cell quality data of the second block that is sent by the network device.
