Solution Overview

Problem

Existing communication networks face challenges in determining Quality of Service (QoS) parameters in a proactive and efficient manner, often relying on iterative trial and error methods that can be time-consuming and resource-intensive.

Innovation Solution

A method is introduced where a base station receives a QoS parameter request for a probing session, determines the relevant QoS parameter, and transmits it to a receiving entity, allowing for proactive QoS determination without impacting existing sessions or resources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If iterative trial and error methods are used to determine QoS parameters, then the determination process can be performed without additional signaling overhead, but the time consumption and resource usage increase significantly

Engineering Contradiction:

Improvetime consumption for QoS determinationVSAvoidcomplexity of QoS determination process

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The patent introduces a probing session mechanism that performs preliminary QoS parameter determination before actual data transmission. The base station proactively determines QoS parameters by establishing a probing session with the transmitting entity, allowing the network to know the QoS characteristics in advance without waiting for iterative trial and error during actual communication.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces a dedicated probing session as an intermediary mechanism between the transmitting entity and the base station. This probing session acts as a mediator that carries out QoS parameter determination independently from the actual data transmission sessions, separating the measurement function from the communication function.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If probing sessions are established to determine QoS parameters proactively, then the speed of QoS determination improves, but additional network resources are consumed

Engineering Contradiction:

Improvespeed of QoS determinationVSAvoidnetwork resource consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The probing session uses partial resources compared to full data transmission sessions. Instead of allocating complete transmission resources for QoS measurement, the system uses a reduced set of resources sufficient only for measuring QoS parameters, thereby minimizing resource consumption while maintaining measurement capability.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The probing session is self-contained and self-managed. It independently establishes, performs measurements, and terminates without requiring resources from actual data transmission sessions. The probing session serves its own purpose of QoS determination without burdening the main communication sessions.

Inventive Principle:

Principle #25Self-service

3Reliability

If QoS parameters are determined without reserving resources, then the base station can provide accurate QoS information without impacting existing sessions, but resource allocation cannot be guaranteed

Engineering Contradiction:

Improveaccuracy of QoS parameter determinationVSAvoidresource allocation flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent extracts the QoS parameter determination function from the actual resource allocation process. The probing session measures QoS parameters by observing network conditions without extracting or allocating actual transmission resources. This separation allows accurate measurement while maintaining full resource availability for existing sessions.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system changes the operational parameters of the probing session to be non-resource-consuming. Instead of using full transmission power, bandwidth, and other resources, the probing session operates with modified parameters that enable measurement while having minimal impact on network resource allocation and existing sessions.

Inventive Principle:

Principle #35Parameter changes

AI summary

Examples include a method to determine a Quality of Service, QoS, parameter, comprising receiving, at a base station, and from a transmitting entity, a QoS parameter request for a session, whereby the request comprises a descriptor for the session and an indication that the session is a probing session. The method further includes determining, at the base station, the QoS parameter related to the probing session; and transmitting, by the base station, the determined QoS parameter to a receiving entity.
