Femto Cell Call Gating via Caller ID Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cellular communication systems lack effective call management solutions that allow users to control incoming calls on their devices, particularly in environments where femto cells provide coverage, leading to unwanted calls and increased operational costs.
Innovation Solution
A femto cell system with a processing unit that enables call gating by monitoring incoming calls, identifying caller IDs, and routing calls based on predefined lists of allowed or blocked numbers, allowing users to customize call handling through a user interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If call gating functionality is integrated into the femto cell, then call management control is improved, but device complexity increases
Solution Approach 1:
The femto cell acts as an intermediary device between the macro cellular network and the user's cellular device. It intercepts incoming calls, identifies caller IDs, checks against allowed/blocked lists, and routes calls accordingly. This mediator approach provides sophisticated call management without requiring complex software on the user's personal device.
Solution Approach 2:
The call management functionality is segmented into distinct operational components: call interception, caller ID identification, list comparison, and call routing. Each component performs a specific function, making the overall system more manageable despite the added complexity of integrating these features into the femto cell.
2Object-affected harmful factors
If caller ID identification and filtering is implemented, then unwanted calls are reduced, but processing time increases
Solution Approach 1:
Users pre-configure lists of allowed and blocked caller IDs before receiving calls. When a call arrives, the femto cell simply compares the caller ID against these pre-established lists rather than performing complex analysis in real-time. This preliminary preparation minimizes processing delays during actual call events.
Solution Approach 2:
The system changes the parameter of call filtering from real-time analysis to pre-configured list matching. By transforming the filtering criterion into a simple database lookup operation rather than a complex evaluation process, the system rapidly identifies and filters unwanted calls with minimal processing time.

AI summary
Embodiments of the disclosed invention include a system and method for providing call gating. For example, in one embodiment, a femto cell is disclosed that includes a processing unit configured to execute instructions to perform operations comprising: enabling a call gating function associated with a cellular device in response to receiving an activation signal from the cellular device, monitoring for an incoming call to the cellular device in response to enabling the call gating function associated with the cellular device; identifying a caller ID associated with an incoming call in response to receiving an incoming call to the cellular device; determining whether the caller ID is on a list of allowed caller IDs associated with the cellular device; and routing the incoming call to the cellular device in response to a determination that the caller ID is on the list of allowed caller IDs associated with the cellular device.
