Virtual Identity Identifier for Roaming Network Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face high expenses for international roaming data services due to limited support from service providers, as they often require agreements with global providers for each country, leading to restricted coverage and resource wastage with preconfigured cards.
Innovation Solution
A computer-implemented method and system that parses allocation requests from terminals to identify matching identity identifiers, allowing virtual identity identifiers to connect to communication networks without the need for physical cards or agreements with each service provider, enabling unrestricted data roaming and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If service providers sign agreements with global service providers to obtain card information for each roaming country, then the terminal can access communication networks in roaming countries, but the supporting number of roaming countries is limited and resource wastage occurs
Solution Approach 1:
The patent creates a virtual identity identifier that copies the essential function of a physical SIM card without requiring actual card resources. The virtual identifier stores user information and authentication data, allowing the terminal to access communication networks in multiple roaming countries without needing physical SIM cards for each country. This eliminates the need for service providers to sign agreements with global providers for each country while maintaining network access capability.
Solution Approach 2:
The virtual identity identifier serves multiple functions that previously required separate physical SIM cards: it provides authentication, stores user information, and enables network access across different roaming countries. A single virtual identifier replaces the need for multiple physical cards and multiple agreements with global service providers, thereby increasing the supporting number of roaming countries without increasing device complexity.
2Ease of operation
If preconfigured physical SIM cards are provided for each roaming country, then the terminal can register and connect to communication networks, but capital expenditures increase and resource wastage occurs
Solution Approach 1:
The patent replaces physical SIM cards with a virtual identity identifier that stores the same essential data (user information, authentication keys, network registration parameters). This virtual copy eliminates the need to physically possess and manage multiple SIM cards for different roaming countries, reducing the quantity of physical resources required while maintaining ease of operation through automated virtual card provisioning.
Solution Approach 2:
The system automatically provisions and manages virtual identity identifiers without requiring manual intervention to physical card insertion or removal. The terminal receives allocation requests, the server assigns appropriate virtual identifiers, and the data is automatically written to the terminal's memory, eliminating the need for users to physically handle multiple SIM cards while maintaining simple operation.
3Reliability
If physical SIM cards with key identifiers are used for international roaming, then data transmission can be completed, but expensive roaming data service expenses are incurred
Solution Approach 1:
The virtual identity identifier contains the same authentication capabilities as physical SIM cards, enabling reliable data transmission through virtual authentication keys stored in the terminal's memory. This eliminates the need for expensive international roaming data services by allowing the terminal to use local network resources authenticated through the virtual identifier, thereby maintaining transmission reliability while reducing service expenses.
Solution Approach 2:
The virtual identity identifier acts as an intermediary between the terminal and the communication network, providing authentication and data management without requiring direct connections to global service providers. This intermediary approach allows the terminal to access local networks in roaming countries through the virtual identifier, avoiding expensive international roaming charges while maintaining reliable data transmission.
Data Source
AI summary
This invention discloses a communication methods, servers, and terminals. Aspects receive an allocation request, used for registering and connecting to the communication network, of an identity identifier from a terminal; parse the allocation request of the identity identifier and acquiring an attribute information of the identity identifier; find, from a plurality of identity identifier candidates, an identity identifier matching with the attribute information of the identity identifier and regard the found identity identifier as the one to be allocated; read the data, used for registering and connecting to the communication network, of the to-be-allocated identity identifier, and send the data, used for registering and connecting to the communication network, of the to-be-allocated identity identifier to terminals.
