Security Circuitry for Temporary Voice Call ID Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication devices face high service fees and inefficient network switching when roaming, as they must use the same phone number and identification number assigned by their home service provider, leading to potential service denial on non-home networks without established roaming agreements.
Innovation Solution
The implementation of security circuitry in wireless communication devices that processes security keys to authorize temporary identification numbers for voice calls, allowing devices to seamlessly switch between networks and access roaming services without incurring high fees by using a temporary 'native' identification number.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wireless communication device uses the same identification number assigned by the home service provider for roaming, then the device can maintain service continuity, but the device incurs high service fees and may face service denial on non-home networks
Solution Approach 1:
The patent segments the identification number into two types: a permanent home network identification number and a temporary roaming identification number. The device maintains the home number for home network services while generating a separate temporary number for roaming networks, allowing service continuity without incurring high roaming fees through proper network selection and number assignment.
Solution Approach 2:
The patent changes the parameter of identification number from a fixed home network number to a variable number that can be temporarily assigned from roaming networks. This parameter change enables the device to switch between different identification numbers based on network conditions, improving service availability while avoiding high fees by using appropriate numbers for each network context.
2Object-generated harmful factors
If a wireless communication device uses a temporary identification number for roaming, then the device can access roaming services with lower fees, but the device requires additional security authentication mechanisms
Solution Approach 1:
The patent introduces a security key as an intermediary element that mediates between the device and the roaming network authentication system. The security key enables the device to prove its identity and authorization to the roaming network without requiring complex multi-factor authentication, thus reducing the complexity barrier while enabling fee-saving roaming operations.
Solution Approach 2:
The patent implements self-service authentication where the device uses its own pre-stored security key to authenticate with roaming networks. This eliminates the need for manual authentication procedures or complex security setups, allowing the device to automatically manage its own authentication while accessing roaming services at lower costs.
3Reliability
If a wireless communication device implements security zones for processing, then the device can enhance security for trusted applications, but the device increases processing complexity and resource requirements
Solution Approach 1:
The patent segments the processing system into distinct security zones: a first zone for untrusted applications and a second zone for trusted applications. This segmentation isolates security-critical operations (such as authentication and temporary number management) in the trusted zone from general applications, enhancing security while organizing processing complexity into manageable modular sections rather than a monolithic structure.
