Video Relay Service Session Initiator for Call Queue Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The establishment of communication sessions involving intermediary services, such as interpretive services for the deaf or hearing-impaired, often requires complex and unintuitive call connection methodologies, leading to the formation of queues and lengthy wait times due to the need for multiple dialing strings and connectionless network configurations.
Innovation Solution
A method and system for efficiently initiating calls in a Video Relay Service (VRS) that allows a video phone to establish a first segment of the communication session with the VRS using a stored network address, forward the called party number, and subsequently establish a second segment with a voice phone, utilizing control logic to manage call queues and prioritize calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple dialing strings and connectionless network configurations are used to establish communication sessions with intermediary services, then the communication session can be established, but the call initiation process becomes complex and unintuitive
Solution Approach 1:
The patent introduces a session initiator as an intermediary component that automatically manages the complex multi-segment dialing process. The session initiator receives a single destination number from the user, resolves the appropriate VRS gateway and segment configuration, and executes the multi-step connection establishment without requiring the user to manually input multiple dialing strings or understand connectionless network configurations.
2Adaptability or versatility
If multiple dialing strings and queue formation are required for interpretive services, then intermediary services can be accessed, but wait times increase
Solution Approach 1:
The session initiator performs preliminary actions by pre-resolving VRS gateway addresses, pre-configuring segment routing, and pre-establishing connection parameters before the actual call is placed. This preparation work is done in advance based on the destination number, so when the user initiates a call, the complex setup is already complete and only the actual connection needs to be established.
Solution Approach 2:
The system implements feedback mechanisms where the session initiator continuously monitors the status of communication session establishment, tracks queue positions, and dynamically adjusts connection attempts based on real-time conditions. This feedback loop allows the system to optimize wait times by retrying failed connections or switching to alternative VRS gateways when available.
3Ease of operation
If conventional point-to-point calling methods are used, then call establishment is simple and direct, but intermediary services such as interpretive services cannot be provided
Solution Approach 1:
The session initiator is designed as a universal component that can handle both simple point-to-point calls and complex calls requiring intermediary services. When a user inputs a destination number, the session initiator automatically determines whether the call requires VRS interpretation services and adapts the connection methodology accordingly. This multi-functionality allows the system to maintain simple user interaction for all call types while providing access to specialized services when needed.

AI summary
A method and system for call initiation and the establishment of a communication session in a video relay service are described. A called party number of a voice phone is entered into a video phone and a first segment of a communication session is established between the video phone and a Video Relay Service (VRS) system according to a network address of the VRS system stored within the video phone. The called party number is forwarded to the VRS system over the first segment of the communication session. A second segment of the communication session is established between the VRS system and the voice phone without any additional interaction by a user of the video phone using the called party number of the voice phone.
