Terminal Frequency Band Detection for Network Access Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In shared wireless cellular networks, compatibility issues between different operators' configurations lead to prolonged service unavailability for terminals, resulting in reduced user experience due to failed network access.
Innovation Solution
A method and apparatus for a terminal to acquire and determine the frequency band of the cell it camps on, performing handover to a different cell if it does not match the predetermined frequency band, ensuring access to a compatible network for stable service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If terminals camp on shared network cells to increase network coverage, then network coverage is improved, but network access reliability deteriorates due to compatibility issues between different operators' configurations
Solution Approach 1:
The terminal performs preliminary detection of frequency band compatibility before attempting network access. By checking whether the frequency band of the camped cell belongs to the terminal's predetermined supported frequency bands, the terminal can identify incompatible shared networks in advance and avoid access failures, thus maintaining reliability while utilizing shared network coverage.
2Area of stationary object
If terminals attempt to access shared networks with incompatible configurations, then network coverage utilization is improved, but service availability deteriorates due to prolonged access failures
Solution Approach 1:
The terminal implements a feedback mechanism where it detects the frequency band of the camped cell, compares it with its predetermined supported frequency bands, and based on this feedback, decides whether to attempt network access or perform handover. This feedback loop prevents prolonged service unavailability by quickly identifying incompatible networks and switching to alternative cells.
3Reliability
If terminals perform frequency band detection and handover operations, then network access reliability is improved, but device complexity increases
Solution Approach 1:
The terminal autonomously performs frequency band detection, compatibility judgment, and handover operations without requiring complex external control systems. The terminal uses its own predetermined frequency band information and the detected frequency band of the camped cell to make autonomous decisions, simplifying the overall system complexity while maintaining high reliability.

AI summary
A method for network access, a terminal, and a storage medium are provided. The method includes that: the terminal acquires a first frequency band corresponding to a first cell where the terminal camps; determines whether the first frequency band belongs to a second frequency band predetermined by the terminal; and performs handover to a second cell which is different from the first cell in response to determining that the first frequency band does not belong to the second frequency band.
