Solution Overview

Problem

Users face challenges in managing data storage on mobile devices, as existing solutions like backup and cloud storage require deleting local copies to free space, leading to a lack of real-time overview of available data and potential storage limitations, especially for streaming applications.

Innovation Solution

A method for Network-Based Personal Data Storage (NB-PDS) that uses a control server and Personal Data Storage Server to establish a data bearer connection between the User Equipment (UE) and a Personal Data Storage Server, allowing access to a file directory structure that reflects both local and network-stored data, ensuring secure and up-to-date data management within the telecommunication network.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If data items are transferred to network storage (backup or cloud storage), then data storage capacity on UE is reduced, but data is no longer locally available or visible on UE

Engineering Contradiction:

Improvedata storage capacity on UEVSAvoidlocal availability of data

Core Design Contradiction:

Quantity of substanceVSLoss of information

Solution Approach 1:

The patent creates a virtual copy of the network storage file directory structure on the UE, allowing users to access and view network-stored data locally without physically copying the actual data files. The UE displays a reflected file directory that mirrors the network storage structure, enabling local visibility while maintaining network-based storage.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent introduces a file directory reflection mechanism as an intermediary between the network storage and the UE's file system. This reflection layer acts as a mediator that presents network-stored data in a locally accessible format without requiring physical data transfer, thus resolving the contradiction between network storage and local availability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If data items are shared towards network application, then data safety is improved, but data storage requirement on UE is not reduced and application-specific access is limited

Engineering Contradiction:

Improvedata safetyVSAvoidapplication-specific access

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements a universal file directory reflection mechanism that works across multiple applications and services. Instead of application-specific sharing, the reflected file directory provides a unified interface that any application on the UE can access, making the network storage solution universally accessible rather than limited to specific applications.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Quantity of substance

If local copy of data is deleted to free space, then storage space on UE is increased, but real-time overview of available data is lost

Engineering Contradiction:

Improveavailable storage space on UEVSAvoidreal-time overview of data

Core Design Contradiction:

Quantity of substanceVSLoss of information

Solution Approach 1:

The patent creates a virtual reflection of the network storage file directory on the UE, allowing users to maintain a real-time overview of network-stored data without occupying local storage space. This reflected directory structure provides immediate visibility into available data while keeping the actual data on the network.

Inventive Principle:

Principle #26Copying

4Adaptability or versatility

If cloud storage system operates independent from mobile telecommunications network, then device compatibility is improved, but security and control are reduced

Engineering Contradiction:

Improvedevice compatibilityVSAvoidsecurity and control

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments the data storage system into two independent but connected parts: network storage (operating within the telecommunication network) and file directory reflection (operating on the UE). This segmentation allows the network storage to maintain security and control within the telecommunication network while the reflection layer provides universal compatibility across devices.

Inventive Principle:

Principle #1Segmentation

AI summary

Method of accessing in a telecommunication network a Network Based Personal Data Storage, NB-PDS, associated with a User Equipment, UE, said telecommunication network comprising a control server and a Personal Data Storage Server, PDSS, enabling access to said NB-PDS, comprising the steps of transmitting an indication of supporting NB-PDS functionality, retrieving, by said control server, in response to receiving said indication, an Access Point Name, APN, of an access point server, for accessing said PDSS through a data bearer connection, establishing, under control of said control server, said data bearer connection between said UE and said access point server, establishing, under control of said access point server, a data connection between said UE and said PDSS over said data bearer connection providing data access by said UE to said associated NB-PDS, and presenting a file directory of said associated NB-PDS in a file directory structure of said UE.
