Video Caller ID Preview via One-Way RTP Session
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing caller ID system does not provide sufficient pre-information about incoming video calls, especially as video communications become more prevalent, allowing telemarketers to mask their identity and leading to unwanted calls, which traditional caller ID cannot effectively address.
Innovation Solution
Implementing a video client pre-screening functionality that allows call recipients to establish a one-way RTP media session to preview the caller before accepting an incoming video call, providing a live video stream of the caller, similar to looking through a peephole, and offering options to accept or decline the call based on the identity of the caller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional caller ID is used for video calls, then call identification is provided, but caller identity can be masked by telemarketers and insufficient pre-information is provided
Solution Approach 1:
The patent implements a preliminary action by establishing a one-way media session before the full video call is accepted. This allows the recipient to preview the caller's video stream in advance, seeing who is calling before committing to the full call. The preliminary media session enables visual verification of caller identity, preventing telemarketers from masking their identity and providing sufficient pre-information about the caller.
2Loss of information
If one-way media session is established for caller preview, then caller visibility is improved, but additional system complexity is introduced
Solution Approach 1:
The patent applies segmentation by dividing the video call establishment process into distinct phases: a preliminary one-way media session for caller preview, and the subsequent two-way media session for full video communication. This segmentation allows the system to manage complexity by handling caller verification separately from the main call functionality, enabling recipients to preview callers without immediately establishing full bidirectional communication.
Solution Approach 2:
The patent uses an intermediary approach by introducing a preliminary media session as a mediator between the incoming call notification and the full video call acceptance. This intermediary layer provides caller visual information without requiring immediate full bidirectional communication, allowing the system to manage complexity by separating the verification function from the main call establishment.
3Productivity
If full two-way video call is established immediately, then communication is established quickly, but user security and trust are compromised
Solution Approach 1:
The patent implements a preliminary verification action before full communication establishment. The system first establishes a one-way media session allowing the recipient to see who is calling, and only after verification does it proceed to establish the full two-way media session. This preliminary action ensures user security and trust while maintaining efficient call establishment by avoiding unnecessary delays for verified callers.

AI summary
The concept of caller identification (ID) may be enhanced by taking advantage of video by allowing a call recipient to see who is calling on an incoming video call. The call recipient may be allowed to make a decision to accept or decline the incoming video call based upon who the call recipient sees (e.g. through a live video stream) attempting to contact them.
