Solution Overview

Problem

Existing solutions for downloading subscription profiles in the mobile radio-communication field require the use of an IP channel to transfer complete data, leading to high data traffic and inefficiency.

Innovation Solution

A method and device that dynamically generate a service profile using an on-board template with executable data, supplemented by data from a remote server, allowing only partial data transmission, reducing the need for IP channels and user intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a complete subscription profile is downloaded over an IP channel, then the service profile data is complete and reliable, but the data traffic over the mobile radio-communication network increases significantly

Engineering Contradiction:
Improvecompleteness of service profile dataVSAvoiddata traffic volume
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The service profile data is segmented into two parts: a complete service profile template stored locally on the device, and only the diversified part (specific instance data) downloaded from the remote server. This segmentation allows the device to have access to complete profile structures locally while minimizing network traffic by downloading only the necessary variable data portions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The service profile template is prepared and stored on the device in advance, containing the complete structure and executable data. When a service profile is needed, the device only requires downloading the diversified part to complete the profile, rather than downloading the entire profile data from scratch each time.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If an IP channel is used to download the complete subscription profile, then the data transmission is reliable, but the complexity of the system increases due to requiring IP channel infrastructure

Engineering Contradiction:
Improvedata transmission reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system is segmented such that the complex service profile template structure is stored locally on the device, while only simple diversified data needs to be transmitted over the network. This reduces the complexity of network infrastructure requirements, allowing transmission over simpler channels without IP while maintaining data reliability through the local template.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If a complete service profile is downloaded, then no user intervention is needed, but the data exchange volume is large

Engineering Contradiction:
Improveuser intervention requirementVSAvoiddata exchange volume
Core Design Contradiction:
Ease of operationVSQuantity of substance

Solution Approach 1:

The service profile is segmented into a complete template stored locally and a diversified part downloaded from the server. The local template ensures that the overall profile structure and service logic are already in place on the device, so only minimal diversified data needs to be exchanged over the network to complete the profile, reducing data exchange volume while maintaining ease of operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The device uses its own stored service profile template to automatically construct the complete service profile by combining it with the received diversified data. This self-service approach eliminates the need for complete profile downloads from the server while maintaining automatic operation without user intervention.

Inventive Principle:
Principle #25Self-service

AI summary

The invention relates to a method 20 for accessing a service subscription profile. A device 14 comprises a memory 144. According to the invention, the memory stores data relating to at least one service subscription profile template. The at least one service subscription profile template includes executable data. The method comprises the following steps: - a server 18 sends to the device a first message 22 including a request for creating or modifying at least one service subscription profile based upon a service subscription profile template; - the device creates or modifies a memory area 32 while executing the executable data, the memory area being associated with a service subscription profile, as an on-board generated service subscription profile, by using the service subscription profile template; - the server sends to the device at least one second message 26 including complementary data relating to the service subscription profile; and - the device stores within the created or modified memory area the complementary data relating to the service subscription profile, so as to complete the stored on-board generated service subscription profile. The invention also relates to corresponding device and system.
