Solution Overview

Problem

Current media resource playing methods in communication technologies often lead to call connection failures due to incomplete message processing, affecting communication efficiency.

Innovation Solution

A media resource playing method where a calling terminal initiates a call and sends a resource obtaining request to a first media server in the IT domain, allowing the media resource to be obtained and played independently of the CT domain, thereby avoiding call connection failures and simplifying the media resource playing procedure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If media resource playing is integrated with CT domain call procedure, then media resource can be delivered during call setup, but call connection fails when signaling is faulty

Engineering Contradiction:
Improvecall connection reliabilityVSAvoidmedia resource playing procedure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent separates media resource playing into an independent IT domain application client, distinct from the CT domain call procedure. The application client independently obtains and plays media resources without relying on CT domain signaling, thus preventing call connection failures while reducing procedural complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an IT domain application client as an intermediary between the user and media resources. This intermediary handles media resource acquisition and playback independently, shielding the CT domain call procedure from potential signaling faults while maintaining media delivery capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If media resource playing is integrated with CT domain call procedure, then media negotiation can be performed, but communication efficiency decreases due to signaling faults

Engineering Contradiction:
Improvecommunication efficiencyVSAvoidmessage processing completeness
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent divides the system into CT domain (for call setup) and IT domain (for media resource management). The application client in the IT domain independently handles media resource requests without depending on CT domain signaling completeness, thereby improving communication efficiency and preventing failures due to incomplete message processing.

Inventive Principle:
Principle #1Segmentation

3Reliability

If media resource is obtained from IT domain, then call procedure is not affected, but requires additional application client interaction

Engineering Contradiction:
Improvecall connection stabilityVSAvoidmedia resource obtaining process
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The application client automatically obtains media resources from the IT domain media server without requiring manual user intervention. The client independently sends resource obtaining requests, receives media resources, and plays them locally, simplifying the user experience while ensuring call stability.

Inventive Principle:
Principle #25Self-service

4Adaptability or versatility

If media resource is obtained from CT domain, then call procedure is integrated, but call connection fails when signaling is faulty

Engineering Contradiction:
Improvemedia resource delivery integrationVSAvoidcall connection reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent separates media resource delivery from the CT domain call procedure by implementing an independent IT domain application client. This segmentation allows the system to maintain adaptability for media delivery while eliminating the reliability issue of call connection failures caused by CT domain signaling faults.

Inventive Principle:
Principle #1Segmentation

AI summary

This application provides a media resource playing method, a related apparatus, and a system, and belongs to the field of communication technologies. In technical solutions provided in this application, when detecting that a calling terminal initiates a call, the calling terminal obtains address information of a first media resource from a first media server via a target application client, and then plays the first media resource based on the address information after receiving a ringing message. In the foregoing process, a media resource may be obtained and played through interaction between the target application client and the first media server, and a call procedure of a CT domain is not affected. In this way, a problem such as a call connection failure that may be caused in an interaction process is avoided, a media resource playing procedure is simplified, and communication efficiency is improved.
