Temporary Routing Number Calling for Selected Caller ID
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users are burdened with carrying multiple computing devices to utilize different phone numbers, leading to inefficiency and waste.
Innovation Solution
A telephony client application allows users to select and originate calls from a temporary routing number (TRN) different from their device number, using a network authentication process to ensure authorization and routing the call through a temporary number.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a user carries multiple computing devices to use different phone numbers, then the user can access different phone numbers, but the user experience becomes cumbersome and resources are wasted
Solution Approach 1:
The patent implements a single computing device that can perform multiple functions by supporting multiple phone numbers through SIM card switching. The device maintains all phone numbers and allows seamless switching between them, eliminating the need for multiple devices while preserving the ability to access different numbers.
Solution Approach 2:
The patent combines multiple phone number functionalities into a single computing device by integrating multiple SIM cards or number profiles. The system merges the capabilities of multiple devices into one unified platform, allowing users to manage and switch between different phone numbers from a single device.
2Adaptability or versatility
If a user carries multiple computing devices to use different phone numbers, then the user can access different phone numbers, but multiple devices are wasted
Solution Approach 1:
The patent makes a single computing device universal by enabling it to support multiple phone numbers through SIM card switching functionality. The device can adapt to different communication needs by switching between stored phone numbers, replacing the need for multiple specialized devices.
Solution Approach 2:
The patent merges the functionality of multiple computing devices into one by combining multiple SIM card slots and number management capabilities in a single device. This consolidation reduces the total quantity of devices needed while maintaining full access to different phone numbers.
3Adaptability or versatility
If Caller ID Spoofing is used to change the displayed calling number, then the displayed number can be changed, but the actual call routing remains tied to the device number
Solution Approach 1:
The patent performs preliminary actions by pre-configuring multiple phone numbers and SIM cards in the device before making a call. The system prepares the appropriate SIM card and phone number selection in advance, ensuring that both the displayed number and the actual call routing are correctly set to the desired number before the call is initiated.
Solution Approach 2:
The patent introduces the SIM card switching mechanism as an intermediary between the user and the call routing system. The SIM card acts as a mediator that physically connects the device to the selected phone number's network identity, ensuring that both Caller ID display and actual call routing consistently reflect the chosen number.

AI summary
When authorized, a user of a computing device, such as a smart phone, may select an originating phone number to initiate a voice call that is different from the telephone number that is assigned to the computing device. The telephone number that is selected as the originating number may be a number that is assigned to another computing device and/or a different user. In response to receiving a request to place an outgoing call using the selected destination number, the network returns a temporary routing number to the computing device. The computing device places a call to the temporary routing number. After receiving the call at the temporary routing number, the network places the outgoing call using the selected originating number. The outgoing call appears to a called party to originate from the selected originating number instead of from the phone number assigned to the computing device.
