Wireless Handover Bandwidth Allocation for Seamless Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handover protocols for wireless connections between heterogeneous networks often result in degradation of signal quality during the transition, leading to inconvenient or impossible continuation of tasks, and may result in complete loss of connection when no suitable alternative is available.
Innovation Solution
A handover control system that includes a probing mechanism to assess the capabilities of new connections and trigger processes to maximize the existing connection's utilization before degradation, prioritizing bandwidth allocation to ensure data buffering and quality maintenance, and network management to suspend or limit data feeds to other users to provide maximum bandwidth to the terminal experiencing signal degradation.

Engineering Contradiction Analysis
1Reliability
If handover is performed based on conventional triggers, then connection continuity is maintained, but connection quality degrades significantly
Solution Approach 1:
The system performs preliminary probing of the new connection's capabilities before handover is triggered. This allows the system to assess whether the new connection will provide adequate quality and to prepare appropriate actions (such as buffering data or adjusting transmission parameters) in advance of the handover event, thereby maintaining both continuity and quality.
Solution Approach 2:
The system implements feedback mechanisms where the probing results about new connection capabilities are used to inform the handover decision. The Connection Manager receives feedback about whether the new connection's capabilities are sufficient and adjusts the handover timing and parameters accordingly, preventing handovers that would result in quality degradation.
2Manufacturing precision
If handover is delayed to maintain quality, then connection quality is preserved, but data loss increases
Solution Approach 1:
When probing indicates that a handover will result in quality degradation, the system takes preliminary actions to buffer critical data and maximize utilization of the existing connection before handover occurs. This allows the system to prepare data for transfer in advance, reducing the impact of the quality-degraded connection and minimizing data loss.
Solution Approach 2:
The system implements a cushioning mechanism by buffering data in advance of the expected handover. This creates a data reserve that can be transmitted during or after the handover event, protecting against data loss even when the new connection has lower quality. The buffer acts as a cushion that absorbs the impact of the transition.
3Loss of substance
If bandwidth is allocated to buffer data before handover, then data loss is minimized, but service to other terminals deteriorates
Solution Approach 1:
The system applies local quality by providing differentiated bandwidth allocation: the terminal experiencing imminent handover receives prioritized bandwidth for buffering critical data, while other terminals continue to receive normal service. This localized resource allocation ensures that only the affected terminal receives enhanced bandwidth temporarily, minimizing impact on overall network productivity.
Solution Approach 2:
The system implements preliminary anti-action by temporarily limiting or suspending data feeds to other terminals only when and where necessary - specifically for the terminal experiencing imminent handover. This targeted approach prevents data loss for the affected terminal while minimizing the duration and scope of impact on other users, allowing normal service to resume quickly after handover.

AI summary
A connection between a communications terminal and a communications network is arranged such that on detection of imminent degradation (30) or loss of such connection, the utilisation of the connection is maximised in advance of such degradation. The network temporarily reallocates the maximum bandwidth that the terminal is capable of using to that terminal, which may result in a small temporary degradation of the bandwidth available to other terminals (33), and the terminal downloads (351) the data most likely to be required next to a cache (in the case of specific web pages, identified by recent accession, bookmarks, or hyperlinks from the page currently being viewed), or a buffer (if the data is being streamed) using this extra bandwidth made available.
