Solution Overview

Problem

In existing methods for allocating phone numbers to subscribers, without an HSS, the process results in an Attach Reject being sent to the UE, requiring the user to restart the device to connect to the network, which is burdensome for the user.

Innovation Solution

A numbering system that includes receiving authentication requests, determining if a phone number is allocated, initiating phone number allocation if not, and responding to location registration requests using the allocated phone number, thereby reducing user burden.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If phone number allocation is performed after authentication information request without HSS, then network resource management is improved, but user operation burden increases due to required device restart

Engineering Contradiction:
Improvenetwork resource management efficiencyVSAvoiduser operation burden
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system performs phone number allocation in advance during the authentication phase, before the location registration request is processed. This preliminary action ensures that when the location registration occurs, the phone number is already allocated and available, eliminating the need for device restart while maintaining efficient network resource management.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces dynamic state tracking for phone number allocation status. The system can adapt its response based on whether the phone number is already allocated or still needs to be allocated, allowing flexible handling of different scenarios without requiring device restart, thus improving both network efficiency and user experience.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If phone number allocation is delayed until after location registration request, then system processing simplicity is improved, but service continuity deteriorates requiring device restart

Engineering Contradiction:
Improvesystem processing simplicityVSAvoidservice continuity
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The system performs phone number allocation before processing the location registration request. By completing the allocation in advance during authentication, the system maintains simple processing logic while ensuring service continuity, as the phone number is ready when needed without requiring device restart.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent ensures continuous service by overlapping the phone number allocation process with the authentication phase rather than waiting for location registration. This continuous action ensures that the useful action of phone number allocation is completed without interrupting the user's connection, maintaining both system simplicity and service reliability.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

A numbering system for allocating a phone number to a subscriber includes first receiving means for receiving an authentication information request for an individual subscriber from an entity that manages mobility of a user equipment, determination means for determining whether a phone number has been allocated to the individual subscriber after the authentication information request has been received, allocation means for starting processing for allocating a phone number to the individual subscriber in response to a determination that a phone number has not been allocated to the individual subscriber, second receiving means for receiving a location registration request for the individual subscriber from the entity, and responding means for responding, in a case where a phone number has been allocated to the individual subscriber before a response to the location registration request is started, to the location registration request using the phone number.
