Multi-Call Forwarding Rule Logic for Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current call forwarding on mobile phones is inflexible, as it cannot distinguish between multiple calling objects and only forwards calls based on a preset number, reducing flexibility and convenience for users.
Innovation Solution
A method and device for call forwarding that allows for a preset multi-call forwarding rule, enabling calls to be forwarded or held based on matching numbers, call duration thresholds, and time ranges, with the option to set forwarding numbers for specific or all contacts, and enabling/disabling the multi-call forwarding function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a preset multi-call forwarding rule is implemented to distinguish different calling objects, then call forwarding flexibility is improved, but device complexity increases
Solution Approach 1:
The patent segments the call forwarding function by creating multiple independent forwarding rules, each associated with different calling objects (contacts). Instead of a single unified forwarding mechanism, the system divides the forwarding logic into separate rule sets that can be independently configured and evaluated, allowing different forwarding behaviors for different callers without requiring a completely complex unified system.
Solution Approach 2:
The patent applies preliminary action by pre-configuring multiple call forwarding rules with specific conditions (calling object, time range, call duration) before actual call forwarding is needed. The system stores these rules in advance and automatically matches incoming calls against the pre-established rule set, eliminating the need for real-time decision complexity during call handling.
2Adaptability or versatility
If multiple call forwarding rules with different conditions are supported, then adaptability is improved, but ease of operation deteriorates
Solution Approach 1:
The patent applies local quality by allowing users to configure specific forwarding rules for specific calling objects (contacts) rather than applying a uniform forwarding configuration to all calls. Each rule can have locally optimized parameters such as contact-specific forwarding numbers, time ranges, and duration thresholds, making the configuration tailored to individual needs while maintaining overall system simplicity through modular rule structure.
3Measurement precision
If call forwarding is based on matching calling numbers with preset rules, then forwarding precision is improved, but measurement precision requirements increase
Solution Approach 1:
The patent uses copying by creating a template or pattern representation of calling numbers in the preset rules. Instead of performing complex real-time analysis of each incoming call, the system copies the calling number and compares it against pre-stored rule patterns, simplifying the matching process while maintaining high precision through exact string comparison or pattern matching algorithms.
