Solution Overview

Problem

Existing content distribution systems face challenges in maintaining reliable data signal distribution to mobile terminal devices, particularly in streaming formats, due to limitations in communication network capacity and bandwidth, leading to potential interruptions and excessive load on the communication service providing side.

Innovation Solution

A distribution request management method that sets a maximum number of requests and reserved numbers for specific contents, managing requests to prevent overload and prioritize reliable distribution, including bandwidth limiting to prevent excessive data signal distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the contents providing server receives and processes distribution requests from multiple processing devices, then the service coverage and user satisfaction improve, but the load on the server increases and may exceed processing capacity

Engineering Contradiction:

Improveservice coverageVSAvoidserver load

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the request management function by introducing a request management means that operates independently from the contents providing server. This segmentation allows the server to focus on content delivery while the request management means handles request queuing, prioritization, and throttling, thereby distributing the processing load and preventing server overload.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements preliminary action by having the request management means pre-process distribution requests before they reach the contents providing server. Requests are evaluated, prioritized, and regulated in advance based on server capacity and network conditions, preventing overload before it occurs and ensuring smooth service delivery.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If data signal distribution capacity is increased to meet higher request volumes, then the productivity improves, but the reliability of data signal distribution decreases due to network limitations

Engineering Contradiction:

Improvedata signal distribution capacityVSAvoiddata signal distribution reliability

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent applies dynamics by making the data signal distribution capacity adjustable rather than fixed. The request management means dynamically regulates the distribution capacity based on real-time server load, network conditions, and request priority levels. This allows the system to optimize between productivity and reliability by adapting capacity to current conditions rather than operating at maximum capacity continuously.

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If the communication service providing side sends all distribution requests to the contents providing server, then the ease of operation improves, but the network load increases beyond acceptable limits

Engineering Contradiction:

Improverequest submission simplicityVSAvoidnetwork data volume

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The patent extracts the request management function from the overall system and implements it as a separate component. This request management means is positioned between the communication service providing side and the contents providing server, extracting and filtering requests before they enter the core distribution system. This maintains ease of operation for users while preventing excessive network load by regulating request flow.

Inventive Principle:

Principle #2Taking out (Extraction)

4Adaptability or versatility

If the maximum number of distributable requests is set to a high value to accommodate more users, then the adaptability improves, but the risk of network overload and service interruption increases

Engineering Contradiction:

Improveuser accommodation capacityVSAvoidservice continuity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements feedback mechanisms where the request management means continuously monitors server load, network conditions, and request accumulation rates. Based on this feedback, the system dynamically adjusts the maximum number of concurrent requests and prioritizes traffic accordingly. This feedback loop allows the system to accommodate more users when conditions permit while preventing overload and maintaining service continuity when capacity is limited.

Inventive Principle:

Principle #23Feedback

AI summary

To provide a distribution request management method and so on in which a communication service providing side can perform data signal distribution while keeping high reliability.A maximum number of distributable requests is set arbitrarily for requests from a mobile communication network 10 to one or plural contents providing servers 31 provided on a communication network 30, the requests being made for distribution of signals including data of contents, and a request management apparatus sends the signal distribution requests to the contents providing servers as long as the number of the requests is within a range not larger than the maximum number of distributable requests.
