IMS Media Type Handling for Video Offloading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile communication systems face challenges in efficiently handling multimedia sessions, particularly with video content, as they require high processing power and battery consumption, and are limited by short-range wireless communication technologies in terms of range and quality.
Innovation Solution
A method for handling media types in IP multimedia communication sessions by presenting media type handling options to users, allowing them to redirect video content from mobile UE to nearby remote terminal equipment, thereby offloading processing and battery usage, using SIP signalling to establish secondary communication sessions with remote terminals via wired or high-speed wireless connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If video content is processed by the mobile UE using short range wireless communication technology, then the video content can be redirected to a nearby display, but the processing power and battery power of the mobile UE are heavily consumed
Solution Approach 1:
The patent extracts the video content processing function from the mobile UE and transfers it to remote terminal equipment. The mobile UE only handles signaling (SIP messages) while the actual video processing and display are performed by external terminals, thereby eliminating the heavy processing and battery consumption on the mobile device.
Solution Approach 2:
The patent introduces an IMS communication system as an intermediary between the mobile UE and remote terminal equipment. The IMS system facilitates the redirection of video content through standardized signaling protocols, allowing the mobile UE to offload processing tasks without requiring direct peer-to-peer communication with display devices.
2Ease of operation
If short range wireless communication technology is used to redirect video content, then the video can be displayed on nearby equipment, but the geographic distance and transmission quality are limited
Solution Approach 1:
The patent makes the video content delivery system universal by supporting multiple transmission paths and terminal types. Instead of being limited to short-range wireless technology, the system can route video content through various networks (mobile network, fixed network, internet) to reach diverse terminal equipment, thereby extending the effective geographic range significantly.
Solution Approach 2:
The patent transitions from a single-dimension short-range wireless connection to a multi-dimensional network architecture. Video content can be routed through different network dimensions (mobile network, fixed network, internet protocol networks), allowing transmission over much longer distances and to a broader range of terminal equipment beyond immediate proximity.
3Ease of operation
If the mobile UE processes video content locally, then the video can be displayed, but the display quality is limited by the mobile UE's display capabilities
Solution Approach 1:
The patent extracts the display function from the mobile UE and assigns it to specialized remote terminal equipment. These remote terminals are specifically designed for high-quality video display with larger screens and better display capabilities, thereby significantly improving video presentation quality while the mobile UE maintains its portability.
Solution Approach 2:
The patent applies local quality by matching different terminal equipment to different user needs and locations. Remote terminal equipment with superior display characteristics is used for high-quality video presentation, while the mobile UE serves as a portable control point. Each terminal's inherent quality characteristics are utilized optimally for its intended function.

AI summary
A method of and mobile User Equipment, UE, for handling media types of an Internet Protocol, IP, multimedia communication session in an IP Multimedia communication Subsystem, IMS, wherein at the receipt of a session set up request message a mobile UE presents media type handling options based on the session set up request message. After receiving media type handling instructions by the mobile UE, based on the presented media type handling options, a session accept message is transmitted by the mobile UE in accordance with the media type handling instructions. Based on the media type handling instructions, media type may be routed by the IMS to terminal equipment remote from the mobile UE.
