Wireless Access Point Status Notification for Bandwidth Conservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, especially in 1xEVDO systems with BCMCS, there is a lack of effective means to notify terminals about unserviceable call connection states before attempting channel allocation, leading to bandwidth waste and noise generation due to unnecessary call connection requests during congestion.
Innovation Solution
The proposed solution involves a status notification method where the wireless communication apparatus determines channel availability and QoS acceptance, broadcasting congestion information to terminals, allowing them to display user notifications and manage resource allocation proactively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal makes a call connection request to inquire about channel allocation, then the terminal can determine whether call connection is possible, but wireless band is consumed and noise is generated during congestion
Solution Approach 1:
The base station performs preliminary channel availability determination and proactively notifies the terminal of the channel allocation status before the terminal makes a call connection request. This allows the terminal to avoid making requests when channels are unavailable, thereby preventing wireless band consumption and noise generation during congestion.
Solution Approach 2:
The base station provides feedback information about channel allocation status to the terminal. This feedback mechanism enables the terminal to make informed decisions about call connection requests based on current network conditions, reducing unnecessary requests during congestion while maintaining reliable connection determination.
2Adaptability or versatility
If the terminal makes a call connection request during congestion, then the terminal attempts to establish connection, but noise is generated and communication of call in progress is adversely affected
Solution Approach 1:
The base station performs preliminary assessment of channel availability and notifies the terminal before the terminal attempts call connection. This preliminary action prevents the terminal from making requests during congestion, thereby avoiding noise generation and interference with ongoing communications while preserving the terminal's ability to attempt connections when appropriate.
3Productivity
If the base station allocates channels without advance notification, then channel allocation is efficient, but the terminal cannot know in advance the unserviceable state
Solution Approach 1:
The base station performs preliminary determination of channel availability and sends notification to the terminal in advance of any call connection attempt. This maintains channel allocation efficiency by using existing channel management processes while simultaneously providing the terminal with advance knowledge of unserviceable states, eliminating information loss.
Data Source
AI summary
A call connection request from an access terminal is suppressed in a state in which the base station judges that the call connection is impossible, thereby suppressing a waste of the wireless band and the generation of noise. A BCMCS management block of an access point receives information indicating whether there is an allocable channel, from a channel management block of the access point, and information indicating whether the start of QoS can be accepted, from a QoS acceptance determination block of the access point, and the BCMCS management block distributes the information to the access terminal. Accordingly, the access point can inform the access terminal that it is not serviceable before channel allocation is attempted.
