Mobile Call Routing via Identifier-Based Terminal Discovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for connecting a first terminal to a second terminal via a mobile radio network are inconvenient and unreliable when the caller does not know the second subscriber's address or when the central database lacks matching entries.
Innovation Solution
A connection service that determines the second terminal based on an identifier, such as a name or function of the second subscriber, using speech recognition, movement profiles, call history, spatial environment, stored data, or data accessible via the network, and calculates a probability for the determination, ensuring a reliable connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connection service uses only the central telephone number database for determining the second terminal, then the system structure remains simple, but the reliability of connection fails when the database lacks matching entries or when the address is unknown
Solution Approach 1:
The connection service is enhanced to perform multiple functions: it not only queries the central telephone number database but also processes alternative identification methods including speech recognition, movement profile analysis, call history examination, and spatial environment verification. This multi-functional approach ensures reliable connection determination regardless of whether the central database has matching entries.
Solution Approach 2:
The connection service acts as an intermediary that mediates between the first terminal and the second terminal by implementing a hierarchical determination process. It first attempts database lookup, then progressively employs alternative methods (speech recognition, movement profiles, etc.) as intermediaries to identify the second terminal when the primary database query fails.
2Ease of operation
If the first subscriber must know the second subscriber's address to make a call, then the connection process remains straightforward, but the ease of operation deteriorates when the address is unknown or difficult to obtain
Solution Approach 1:
The requirement for address information is extracted and removed from the mandatory input for making calls. The connection service now accepts alternative identifiers such as spoken names, movement patterns, or call history references, allowing users to initiate calls without knowing or providing the second subscriber's address.
Solution Approach 2:
The connection service performs self-service by automatically determining the second terminal through multiple intelligent methods. Instead of requiring the user to provide precise address information, the system autonomously queries databases, analyzes speech patterns, examines movement profiles, and reviews call histories to identify and connect to the intended recipient.
3Ease of operation
If the connection service accepts multiple types of identifiers beyond address, then the ease of operation improves, but the device complexity increases due to additional processing requirements
Solution Approach 1:
The connection service implements a dynamic identification system that adapts its processing methods based on the available input. When a simple database query suffices, it uses that lightweight approach. When alternative identifiers are provided (speech, movement patterns, etc.), the system dynamically activates the appropriate complex processing routines, adjusting its operational complexity to match the identification needs.
