Mobile Device Capability Change Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile device capability management systems provide only coarse information about software versions, lacking granularity in tracking changes to specific components and functionalities, which hinders operators' ability to manage mobile device capabilities effectively.
Innovation Solution
A method for representing mobile device capabilities as two profiles, one maintained by the network operator and another in the device, allowing for detailed change information to be assessed and updated, with a two-step approach to detect and process capability changes, including qualitative and quantitative parameters to determine the necessity and extent of updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If detailed capability change information is tracked and updated, then measurement precision and information completeness improve, but device complexity and processing overhead increase
Solution Approach 1:
The capability management system is segmented into two independent profiles: a first profile maintained by the network operator and a second profile maintained in the mobile device. This segmentation allows each profile to be managed separately, reducing the complexity of tracking all capability changes centrally while maintaining precise detection of actual changes through local monitoring in the device.
Solution Approach 2:
The second profile in the mobile device acts as an intermediary that locally tracks capability changes and provides this information to the network operator. This intermediary mechanism enables precise detection of capability changes without requiring the network operator's system to directly monitor and manage all device-level changes, thereby reducing overall system complexity.
2Loss of information
If comprehensive capability updates are performed, then information completeness improves, but network traffic and processing time increase
Solution Approach 1:
The system extracts and maintains capability information locally in the mobile device's second profile, separate from the network operator's first profile. This extraction allows the device to autonomously track capability changes without requiring continuous network communication for every change, reducing network traffic and processing time while maintaining information completeness.
Solution Approach 2:
The mobile device's second profile performs self-service by automatically tracking and recording capability changes locally. This self-service mechanism eliminates the need for the network operator to continuously query and update the device, reducing both network traffic and processing time while ensuring complete capability information is captured and reported when needed.
3Speed
If frequent capability status checks are performed, then detection timeliness improves, but network traffic and energy consumption increase
Solution Approach 1:
The system performs preliminary action by pre-establishing the second profile in the mobile device that is configured to automatically detect and record capability changes. This preliminary setup eliminates the need for frequent status checks by the network operator, as the device proactively identifies and reports changes, improving detection timeliness while reducing network traffic and energy consumption associated with continuous polling.

AI summary
An improved approach to mobile device capability management is described herein where a capability management device is provided at a mobile communication network. Upon change of a mobile device capability, a related notification is sent to the capability management device which applies a policy decision whether to track the capability change at the network side or not. Should the decision be ‘yes’, the capability management device starts a device management session to collect further information on a mobile device capability change beyond the information made available with the mobile device capability change notification. After retrieval of the mobile device capability change information, the capability management device will update its mobile device capability state accordingly.
