Personalized Indicia Porting via Service Provisioning Database
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless packet data service networks face challenges in managing unique Personal Information Numbers (PINs) for mobile communications devices, particularly when devices are replaced or reassigned, leading to inconvenient updates in peer-to-peer messaging and service provisioning.
Innovation Solution
A method and system for porting a personalized PIN from a first mobile communications device to a second device, involving secure peer-to-peer communication to transfer identity information and negotiate with a network node for reassignment of the PIN to the new device's identifier, ensuring seamless service continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a unique PIN is assigned to each mobile device for service authentication and peer-to-peer messaging, then service security and device identification are improved, but device complexity and service management burden increase when devices are replaced or reassigned
Solution Approach 1:
The patent introduces a service provisioning database as an intermediary between mobile devices and the network. This database stores the mapping relationships between PINs and device identifiers, automatically managing PIN assignments and updates. When a device is replaced, the intermediary system handles the PIN reassignment process, eliminating the need for manual PIN management by users and reducing service management complexity.
2Reliability
If PIN updates are required when a device is replaced or reassigned, then unique device identification is maintained, but user convenience and contact list synchronization deteriorate
Solution Approach 1:
The system performs preliminary actions by pre-configuring the service provisioning database with device identifier information before device replacement occurs. When a device is replaced, the database already contains the necessary mapping information, enabling automatic PIN reassignment without requiring user intervention for updates. This preliminary preparation eliminates the burden of manual PIN updates for users and their contact lists.
Solution Approach 2:
The patent implements a self-service mechanism where the service provisioning database automatically manages PIN assignments and updates based on device identifier changes. The system autonomously handles PIN reassignment when devices are replaced or reassigned, without requiring manual user input or contact list synchronization. This self-service approach maintains device identification reliability while significantly improving user convenience.
3Productivity
If dynamic IP address assignment is implemented for packet-switched networks, then network resource utilization is improved, but service continuity and message routing reliability worsen when IP addresses change
Solution Approach 1:
The patent introduces a PIN-to-IP address mapping mechanism mediated by the service provisioning database. Instead of directly routing messages using IP addresses that may change dynamically, the system uses the stable PIN as an intermediary identifier. The database maintains the mapping between PINs and current IP addresses, enabling reliable message routing even when dynamic IP addresses change. This intermediary approach preserves both network resource utilization benefits and message routing reliability.

AI summary
In one embodiment, a scheme is provided for porting a personalized indicium, i.e., a Personal Information Number or PIN, from a first mobile communications device to a second mobile communications device. Upon receiving identity information from the first mobile communications device via a secure peer-to-peer communication session, the second mobile communications device is operable to negotiate with a network node using at least a portion of the received identity information for reassigning the PIN to an identifier associated therewith. Upon successfully porting the PIN to the second mobile communications device, a service provisioning database is accordingly updated.
