Profile Handling Entity for Network Subscription Migration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mechanisms for handling network subscriptions of subscriber devices locked to a specific mobile network operator (MNO) are inadequate, as they do not efficiently allow for switching between different network operators, limiting device migration and contractual agreement enforcement.
Innovation Solution
A method and entities for handling network subscriptions, involving a profile handling entity that obtains and processes request messages for new subscriptions, transmitting release requests when identity mismatches are detected, and receiving release responses to allow target subscription management entities to download new subscriptions to subscriber devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a subscriber device is locked to a specific MNO using existing mechanisms, then the MNO can control subscription switching and enforce contractual agreements, but the device cannot migrate to another MNO and the handling mechanism is inadequate
Solution Approach 1:
The patent introduces a profile handling entity as an intermediary between the subscriber device and subscription management entities. This intermediary manages the lock status and coordinates subscription downloads, enabling controlled migration between MNOs while maintaining reliability of subscription control through centralized management of the lock mechanism
Solution Approach 2:
The patent implements a dynamic lock mechanism where the lock status can be changed from locked to unlocked through coordinated actions between entities. The system transitions from a static locked state to a flexible state where migration is permitted, allowing the device to adapt between different MNOs while maintaining control through defined procedures
2Productivity
If existing lock mechanisms are used, then MNOs can enforce contractual agreements, but the mechanisms are inadequate for efficient subscription handling and migration control
Solution Approach 1:
The patent combines multiple functions into the profile handling entity, which manages lock status, coordinates with subscription management entities, and controls profile downloads. This consolidation improves subscription handling efficiency by centralizing control in a single entity that can efficiently manage the entire migration process
Solution Approach 2:
The patent implements feedback mechanisms where the profile handling entity receives lock status information from subscription management entities and uses this information to control profile download permissions. This feedback loop enables efficient automated decision-making regarding subscription migration while maintaining proper control protocols

AI summary
There is provided mechanisms for handling network subscriptions of a subscriber entity having a network subscription locked to a source subscription management entity. A method is performed by a profile handling entity. The method comprises obtaining a request message for download of a new network subscription handled by a target subscription management entity, the request message comprising identity information of the target subscription management entity. The method comprises transmitting, when there is a mismatch between the identity information and reference identity information, a release request message of the network subscription to the source subscription management entity via the target subscription management entity. The method comprises receiving, from the source subscription management entity via the target subscription management entity, a release response message of the network subscription. The method comprises allowing the target subscription management entity to download the new network subscription to the subscriber entity upon successful verification of the release response message.
