WebRTC Gateway Server for Seamless Mobile Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
WebRTC experiences poor user experience and inefficient usage of mobile device resources due to its over-the-top application nature, lack of seamless operation during sleep mode, and unsupported IP address changes on mobile devices, leading to battery drain and fragmented communication services.
Innovation Solution
Implementing WebRTC as a hybrid or native browser-based application on mobile devices, utilizing WebRTC gateway servers to authenticate and access multimedia services through IMS and XMPP platforms, enabling seamless communication and IP address changes, and optimizing quality of service for voice and video calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If WebRTC is implemented as an over-the-top application on mobile devices, then browser-to-browser real-time communication capability is enabled, but user experience deteriorates and radio resources are inefficiently used
Solution Approach 1:
The patent introduces a network operator's infrastructure as an intermediary between mobile devices. The operator's network manages WebRTC sessions, providing authentication, authorization, QoS control, and seamless operation during network transitions. This mediator resolves the contradiction by enabling real-time communication while maintaining optimal user experience through operator-managed services rather than pure peer-to-peer over-the-top applications
2Reliability
If sleep mode is disabled to maintain WebRTC service access, then communication continuity is improved, but battery consumption increases
Solution Approach 1:
The patent implements preliminary registration and authentication mechanisms where mobile devices register with the network operator's system before entering sleep mode. The operator's network maintains session information and can wake devices seamlessly when communication is needed, eliminating the need to disable sleep mode while preserving communication continuity
3Reliability
If authentication is required before initiating WebRTC services, then network security is improved, but service accessibility deteriorates
Solution Approach 1:
The patent implements preliminary authentication where mobile devices authenticate with the network operator's system in advance. Once authenticated, users gain seamless access to WebRTC services without repeated authentication prompts, maintaining security while improving accessibility and user experience
4Device complexity
If WebRTC operates without operator service optimization, then implementation simplicity is improved, but radio resource usage deteriorates
Solution Approach 1:
The patent introduces the network operator's infrastructure as a mediator that optimizes radio resource usage for WebRTC traffic. The operator's network provides QoS control, traffic management, and efficient resource allocation, resolving the contradiction by maintaining implementation simplicity while dramatically improving radio resource efficiency through operator-managed services

AI summary
Techniques pertaining to seamless WebRTC support on mobile appliances are described. In one aspect, a method includes one or more processors of one or more gateway servers receiving from a browser-based application executed by a mobile device a request for access to multimedia provided by a multimedia access platform. The method also includes the one or more processors retrieving information related to a profile associated with a user of the mobile device from an identity and access management server. The method further includes the one or more processors enabling the browser-based application to receive from the multimedia access platform one or more types of multimedia based at least in part on the profile associated with the user of the mobile device.
