Cell Access Method Speed-Based Network Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication technology, terminals often access unintended networks, which affects communication quality, as operators deploy multiple networks to improve quality for specific types of terminals, leading to interference from other networks.
Innovation Solution
A cell access method where a terminal reports its moving speed to a base station, and if access is rejected, it selects a neighboring cell from a different network for access, preventing access to other networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If operators deploy multiple different types of networks for different types of terminals, then communication quality for specific terminals is improved, but terminals may access cells in unintended networks causing interference and degradation of communication quality
Solution Approach 1:
The base station changes the parameter of access rejection based on terminal moving speed. When terminal speed exceeds a threshold, the base station rejects access to the first network and redirects the terminal to the second network, thereby preventing network interference while maintaining communication quality for high-speed terminals
Solution Approach 2:
The patent introduces an intermediary mechanism (access rejection indication information) that mediates between the terminal's access request and the network's quality requirements. This intermediary controls terminal access behavior based on speed conditions, preventing harmful network interference while preserving communication quality
2Object-affected harmful factors
If the base station rejects terminal access to the first network based on moving speed, then network interference is prevented, but the terminal requires alternative cell selection which increases access complexity
Solution Approach 1:
The base station performs preliminary action by sending access rejection indication information containing neighbor cell information before the terminal attempts access. This preliminary guidance simplifies the terminal's subsequent cell selection process, reducing access complexity while preventing network interference
Solution Approach 2:
The patent implements feedback by providing the terminal with specific neighbor cell information (second cell) in the access rejection indication. This feedback guides the terminal to select an appropriate alternative network, simplifying the access process while preventing interference with the first network

AI summary
The present disclosure relates to a cell access method including: in the process that a terminal accesses a first cell, reporting, by a terminal, its own moving speed to a base station corresponding to the first cell; and if the base station determines that the terminal is not allowed to access the first cell according to the moving speed, sending, by the base station, access rejection indication information to the terminal and selecting, by the terminal, according to the access rejection indication information, a second cell in a second network for access. In response to determining, by the base station, that the terminal is not allowed to access the first cell, the terminal can only access the second cell in the second network.
