Solution Overview

Problem

Current methods for providing access network related information are space inefficient and require large memory storage and network payloads due to redundant data in the Access Network Discovery and Selection Function (ANDSF) management object.

Innovation Solution

The implementation of a hierarchical tree-based system with reference nodes that specify sub-trees containing specific access network related information, allowing for efficient provisioning by eliminating duplicate data and reducing storage and network payload requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If access network related information is provided using complete management object structure, then information completeness is improved, but memory storage requirements increase

Engineering Contradiction:
Improveinformation completenessVSAvoidmemory storage requirements
Core Design Contradiction:
Loss of informationVSQuantity of substance

Solution Approach 1:

The patent implements a hierarchical management object structure where sub-trees are nested within parent nodes. Complete management objects contain sub-trees that may themselves contain further nested sub-trees, allowing information to be organized in a compact hierarchical format that reduces redundant storage while maintaining completeness.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The patent uses reference nodes that contain references to sub-trees already stored elsewhere in the management object structure. Instead of copying entire sub-trees multiple times, the system stores each sub-tree once and creates lightweight reference nodes that point to it, significantly reducing memory storage requirements while preserving information completeness.

Inventive Principle:
Principle #26Copying

2Productivity

If access network related information is transmitted over network, then information provisioning is achieved, but network payload size increases

Engineering Contradiction:
Improveinformation provisioningVSAvoidnetwork payload size
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The patent replaces redundant sub-tree copies with reference nodes containing references to the actual sub-trees. When transmitting management objects over the network, this approach sends minimal reference data instead of duplicating large sub-tree structures, dramatically reducing network payload size while maintaining the ability to provision complete information.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent extracts frequently reused sub-trees from their original contexts and stores them as separate entities in the management object structure. Reference nodes then point to these extracted sub-trees, allowing the system to transmit only the necessary reference information over the network rather than entire redundant data structures.

Inventive Principle:
Principle #2Taking out (Extraction)

3Quantity of substance

If reference nodes are used to specify sub-trees, then storage efficiency is improved, but system complexity increases

Engineering Contradiction:
Improvestorage efficiencyVSAvoidsystem complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent segments the management object structure into distinct components: parent nodes, child nodes, and reference nodes. Each segment has a specific function, and the hierarchical segmentation allows the system to manage complexity through modular organization while achieving storage efficiency through reference-based structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates a universal reference node structure that can reference any sub-tree within the management object hierarchy. This multi-functional reference mechanism works across different types and levels of sub-trees, providing a unified approach to reducing storage requirements without requiring separate mechanisms for different data types.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A control apparatus initiates, in response to a predetermined condition being satisfied, a provisioning, to a communications terminal, of information of a portion of a management object. The control apparatus generates, and transmits to the communications terminal, one or more commands comprising information of the portion including information of a reference node which is a leaf node of the management object and which contains reference information specifying a sub-tree comprising specific access network related information. The communications terminal receives the one or more commands, stores the information of the portion comprised in the one or more commands in accordance with the one or more commands, and acquires the specific access network related information of the sub-tree using the reference information of the reference node included in the information of the portion.
