Intelligent Call Identification with Context Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional call-forwarding systems do not provide sufficient information to recipients about the origin of forwarded calls, leading to difficulties in managing calls appropriately based on the voice service used by the caller.
Innovation Solution
The system intelligently forwards calls to a mobile device, generating an alert message with context information such as caller ID and service details, allowing users to manage calls based on the origin and context before accepting or rejecting them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If call forwarding is implemented without context information, then call routing functionality is achieved, but call management capability deteriorates due to lack of origin information
Solution Approach 1:
The system performs preliminary actions by extracting and preserving context information (caller ID, service type, routing details) from the original call before forwarding occurs. This pre-extraction of information enables the receiving device to display comprehensive call details and make informed decisions about call handling, thus improving call management capability while preventing information loss.
Solution Approach 2:
The patent introduces an intermediary mechanism (the call forwarding system with context extraction) that acts as a mediator between the original call and the forwarded call. This intermediary captures and transmits contextual information alongside the call routing, enabling the receiving device to identify call origins and manage calls appropriately without losing critical information.
2Adaptability or versatility
If all forwarded calls are routed to mobile device, then call accessibility is improved, but call discrimination capability deteriorates due to inability to distinguish call sources
Solution Approach 1:
The system performs preliminary extraction of caller identification information, service type, and routing context before the call is forwarded to the mobile device. This advance preparation ensures that when the call reaches the mobile device, comprehensive information is already available for display, enabling users to discriminate between different call sources while maintaining universal accessibility.
Solution Approach 2:
The system implements feedback by providing the mobile device with detailed context information about the forwarded call's origin. This feedback loop enables the user to see which service or location is calling, allowing them to make informed decisions about whether to answer, thus maintaining call accessibility while restoring call discrimination capability.
3Measurement precision
If context information is extracted and transmitted with forwarded calls, then call identification accuracy is improved, but system complexity increases
Solution Approach 1:
The patent applies extraction by isolating and removing only the essential context information (caller ID, service type, routing details) from the complete call data. This selective extraction achieves accurate call identification without requiring the transmission or processing of unnecessary information, thus improving identification accuracy while limiting the increase in system complexity to only what is essential.
Solution Approach 2:
The system applies local quality by providing different levels of context information to different components of the call forwarding system. Each component receives and processes only the specific information it needs, rather than all possible data. This localized information distribution achieves precise call identification while keeping individual system components relatively simple.
Data Source
AI summary
A network device receives, from a switching node, a forwarded call directed to a particular mobile terminal and holds the forwarded call. The network device generates an alert message including context information for the forwarded call and sends, to the mobile terminal, the alert message. Information from the alert message is presented to a user of the mobile terminal in advance of receiving the call. After sending the alert message, the network device routes the forwarded call to the mobile terminal.
