Service Group Ownership Transfer in CPNS

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In Converged Personal Network Services (CPNS), when the owner of a service group intends to leave or abandon ownership, the group cannot be managed by any other personal network elements (PNEs), leading to operational disruptions since there is no mechanism for transferring ownership.

Innovation Solution

A method where the CPNS server receives an owner transfer request from a PNE and selects a new owner from the existing PNEs within the service group, ensuring seamless ownership transfer to maintain normal operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the service group owner leaves or abandons ownership, then the service group cannot be managed by any other PNEs, but this leads to operational disruptions and loss of service continuity

Engineering Contradiction:

Improveservice group operation continuityVSAvoidservice group management

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent implements a preliminary action by establishing an ownership transfer mechanism before the owner actually leaves. When the owner sends a leave request, the system proactively selects a new owner from existing PNEs and transfers ownership, preventing the operational disruption that would otherwise occur. This anticipatory approach ensures service continuity by having a replacement ready before the gap occurs.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If no ownership transfer mechanism exists, then the service group structure remains simple, but the service group becomes inoperable when the owner leaves

Engineering Contradiction:

Improveservice group operabilityVSAvoidownership transfer mechanism

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system implements self-service by automatically selecting a new owner from the existing PNEs when the current owner leaves, without requiring manual intervention from external administrators. The CPNS server autonomously performs the selection and transfer process, maintaining service group operability while keeping the mechanism relatively simple and self-contained.

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If the owner can leave freely without transfer mechanism, then the owner has flexibility to leave, but the service group loses its management capability

Engineering Contradiction:

Improveowner flexibility to leaveVSAvoidservice group management capability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The CPNS server acts as an intermediary between the leaving owner and the service group. It receives the owner's leave request, processes the ownership transfer by selecting a new owner, and ensures the service group maintains its management capability throughout the transition. This intermediary role preserves both owner flexibility and service group reliability.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A method of transferring ownership of a service group (SG) for a communication system comprising a converged personal network service (CPNS) server is disclosed. The service group comprises a first plurality of personal network elements (PNEs), and the method comprises the CPNS server receiving an owner transfer request from a first PNE of the service group; and the CPNS server selecting a second PNE from the first plurality of PNEs of the service group, to transfer the ownership of the service group from the first PNE to the second PNE.
