Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In DECT network clusters, the uncertainty of using Real-time Transport Protocol Peer To Peer (RTP P2P) or RTP Relay for VOIP calls leads to long waiting times and communication failures, resulting in poor call experiences due to limited wireless coverage and network privileges.

Innovation Solution

A media interaction method that establishes communication with a DECT host through a constructed network cluster, using RTP P2P initially and switching to RTP Relay if no RTP is received from the second account, ensuring optimal call setup and maintenance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If RTP P2P communication manner is used initially, then call setup speed is improved, but communication reliability deteriorates due to uncertainty of interaction

Engineering Contradiction:

Improvecall setup timeVSAvoidcommunication reliability

Core Design Contradiction:

Loss of timeVSReliability

Solution Approach 1:

The system dynamically switches between RTP P2P and RTP Relay communication modes based on real-time interaction results. Initially attempts RTP P2P for fast setup, and if no RTP is received, automatically transitions to RTP Relay through the DECT host, ensuring both speed and reliability

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The DECT host acts as an intermediary in the fallback mechanism. When direct P2P communication fails, the host mediates the call by establishing RTP Relay communication, ensuring the call can still be completed through an intermediate node

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If communication protocol is predetermined, then communication reliability is improved, but adaptability deteriorates due to network privilege variations

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidprotocol adaptability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The communication protocol is not fixed but dynamically selected based on network conditions and device privileges. The system adapts between RTP P2P and RTP Relay modes, allowing both reliable predetermined protocols and flexible adaptation to different network scenarios

Inventive Principle:

Principle #15Dynamics

AI summary

The present application discloses a media interaction method in a Digital Enhanced Cordless Telecommunications (DECT) network cluster. Communication with a DECT host is established through a DECT network cluster constructed in advance, to obtain first account information allocated by the DECT host, and information of a first call request to call a second account is sent to the DECT host, so as to make a call to the second account in a first communication manner. If no Real-time Transport Protocol (RTP) from the second account is received, information of a second call request to call the second account is sent to the DECT host, so as to make a call to the second account in a second communication manner. Embodiments of the present disclosure can solve the technical problem of a communication failure and reduce a waiting time for communication, thereby achieving optimal Voice over Internet Protocol (VOIP) call experience.
