Transparent Media Channel Setup for Faster IMS Application Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional IMS architecture faces challenges in quickly deploying new applications due to the need for multiple functional entities to be upgraded and renovated, limiting the introduction of new applications and increasing deployment difficulties, especially with the emergence of interactive applications like AR/VR and the integration of new media functions.
Innovation Solution
A communication method and system that utilizes a signaling control network element and a media control network element to create a transparent transmission channel, allowing direct data transmission between terminal devices and application entities without requiring updates to the existing system, thereby facilitating the deployment of new applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a new application is added to the conventional IMS architecture by adding a new media line in SDP, then the application functionality is achieved, but multiple functional entities (SBC, P-CSCF, TAS, MRFP, IBCF, TrGW) require upgrading and renovation, increasing system complexity and deployment difficulty
Solution Approach 1:
The patent introduces a media gateway as an intermediary component that handles media resource management and application deployment independently from the core IMS functional entities. This mediator allows new applications to be deployed in the media gateway without requiring upgrades to SBC, P-CSCF, TAS, MRFP, IBCF, or TrGW, thus resolving the contradiction between adaptability and system complexity
Solution Approach 2:
The patent segments the IMS architecture by separating the media resource management function into an independent media gateway component. This segmentation allows the core IMS entities to remain unchanged while new applications are deployed in the segmented media gateway, reducing the ripple effect of upgrades across the entire system
2Adaptability or versatility
If multiple functional entities are upgraded to support new applications, then new application functionality is achieved, but deployment time and operational disruption increase
Solution Approach 1:
The patent performs preliminary action by pre-configuring the media gateway with application deployment capabilities before they are needed in the core IMS. The media gateway is prepared in advance to handle new applications, so when deployment is required, it can be done quickly without triggering cascading upgrades across multiple functional entities, thus reducing deployment time and operational disruption
3Reliability
If the conventional IMS architecture is used with traditional media lines, then system stability is maintained, but media resource utilization efficiency is low
Solution Approach 1:
The patent changes the parameters of media resource management by implementing a media gateway that dynamically allocates and manages media resources based on actual application needs. This allows for more efficient utilization of media resources while maintaining system stability through controlled parameter changes in the media gateway without affecting the stability of the core IMS architecture

AI summary
A communication method, a signaling control network element, a media control network element and a communication system. The communication method comprises: acquiring a transparent transmission channel creation request; performing, according to the transparent transmission channel creation request, negotiation processing on a media control network element and a first terminal device corresponding to a first terminal identifier, so as to create a transparent transmission channel between the media control network element and the first terminal device; obtaining a first resource identifier of an application entity according to the transparent transmission channel creation request; and sending the first resource identifier to the media control network element, so that the media control network element determines a data transmission relationship between the transparent transmission channel and the application entity corresponding to an application identifier.
