Service Call Identification via Temporary Online Directory
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In O2O business scenarios, service receivers face challenges in accurately identifying service calls from unfamiliar numbers, often mistaking them for unwanted calls, leading to missed important communications or unnecessary filtering.
Innovation Solution
A computer-implemented method and system that allows service providers to register characteristic information of service calls with service receivers, enabling authorized registration and identification of service calls through a temporary directory, ensuring service calls are recognized and distinguished from unwanted calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If phone book directory is adopted to store acquaintance phone numbers, then unwanted calls can be filtered, but service calls from strange numbers may be missed
Solution Approach 1:
The patent introduces an online database as an intermediary between the phone book directory and the incoming call. This database stores and provides service call information, acting as a mediator that supplements the limited phone book directory. When a call comes in, the system queries this online intermediary to determine if it's a service call, thus resolving the contradiction between filtering unwanted calls and identifying service calls accurately.
Solution Approach 2:
The patent transitions from a single-dimension local phone book storage to a multi-dimension solution combining local storage with online database querying. By adding the online dimension, the system can identify service calls without requiring them to be pre-stored locally, thus maintaining filtering capability while improving identification accuracy.
2Object-affected harmful factors
If online database is used to mark crank calls in real-time, then unwanted calls can be identified, but the same database cannot provide personalized filtering for different users
Solution Approach 1:
The patent segments the call filtering system into multiple components: a global online database for general crank call information, local phone book directory for personal contacts, and a new service call information database for user-specific service calls. This segmentation allows each component to serve its specific function, enabling both general crank call identification and personalized service call recognition simultaneously.
Solution Approach 2:
The patent implements local quality by allowing different filtering rules and information sources for different users. Each user has their own service call information stored locally, tailored to their specific service providers. This enables personalized filtering where the same calling number might be identified as a service call for one user but filtered as unwanted for another.
3Object-affected harmful factors
If all strange calls are blocked to filter unwanted calls, then advertisement and scam calls are reduced, but important service calls are missed
Solution Approach 1:
The patent applies preliminary action by pre-storing service call information in the online database and local device before the actual call occurs. When a service provider calls, the system has already prepared the information needed to identify it as a service call. This preliminary preparation ensures that service calls are recognized and not blocked, while still allowing filtering of unwanted calls.

AI summary
A method, system, and computer program product, include receiving a request for registration from a service provider, upon the service receiver having authorized the request for registration, registering characteristic information of the service call in a user device of a service receiver, and upon a lapse of time, deregistering the characteristic information from the user device.
