Mobile Device Multiple Number Assignment Module Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile devices can only support one number assignment module for data services, leading to incorrect billing when switching between dual or multiple number assignment modules, as they use the same data credentials for both voice and data services, and not all carriers require or support dual NAM features.
Innovation Solution
A method to configure mobile devices to support multiple number assignment modules, allowing separate data billing by checking if a second NAM supports data connectivity and modifying credentials on-the-fly to enable flexible data connectivity and billing options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile device uses the first data credentials for data services, then data connectivity is maintained, but the network bills the first NAM subscriber for data services even when the user has switched to the second NAM
Solution Approach 1:
The patent implements dynamic credential selection by modifying the data credentials on-the-fly based on the currently active NAM. The system dynamically determines which NAM is active and automatically switches between different data credential sets (first data credentials for NAM1, second data credentials for NAM2), ensuring that data billing matches the active voice service subscriber.
2Adaptability or versatility
If the mobile device supports dual NAM features, then users can register the phone with more than one number, but not all carriers and customers require or support this feature
Solution Approach 1:
The patent implements local quality by providing different configuration options for different carriers and use cases. The system includes configuration parameters that can be set to enable or disable dual NAM support, and to control whether data credentials are shared or separate. This allows carrier A to disable the feature while carrier B enables it for specific customers, reducing complexity where not needed while maintaining versatility where required.
3Object-generated harmful factors
If the mobile device uses separate data credentials for each NAM, then accurate separate billing is achieved, but the device complexity increases
Solution Approach 1:
The patent segments the data credential storage into separate storage locations: first data credentials stored in a first location associated with NAM1, and second data credentials stored in a second location associated with NAM2. The system includes logic to selectively access the appropriate credential set based on the active NAM, providing accurate billing through structured segmentation while managing complexity through organized storage architecture.

AI summary
A method and apparatus for configuring a mobile device capable of supporting multiple number assignment modules, the method writing a first configuration parameter to indicate whether the mobile device should support multiple number assignment modules; specifying a second configuration parameter to indicate whether the mobile device should support data connectivity on a second or subsequent number assignment module; and setting a third configuration parameter to indicate whether separate billing should occur for data usage on the multiple number assignment modules. Also, a method and apparatus for data connectivity on a mobile device supporting multiple name assignment modules, the method checking, subsequent to transitioning to a second name assignment module, whether the second name assignment module supports data connectivity; responsive to the checking, determining whether separate billing is required for the second name assignment module; and responsive to the determining, establishing a data connection.
