IVPN, or Internet Virtual Personal Number Network, is a technology used to provide VoIP (Voice over Internet Protocol) services. It allows users to connect to a phone or mobile data network and make calls or texts directly from their computer or mobile device without having to deal with traditional telephone operators.
-
Core Network: This is the central network that connects all devices. It uses a protocol like Open Short Message Protocol (OSMP) or Virtual Mobile Network Protocol (VMNP) to manage voice calls.
-
Core Exchange: This is the main exchange point where the core network is located. It uses a protocol like Protocol Control Message Protocol (PCMP) to route calls.
-
Routing Tables: These are used to determine which core exchange to use for incoming calls and which core network to use for outgoing calls. Routing tables are organized in a hierarchical structure, with the core network at the top and the core exchange at the bottom.
-
Core Exchange Management: This involves managing the core exchange, including routing tables, trunking, and other administrative tasks.
Advantages of an IVPN:
-
Centralized Management: The core exchange handles routing and other administrative tasks, making it easier to manage and secure.
-
Reduced Administrative Complexity: Instead of having multiple core exchanges for different regions, a single core exchange handles everything, reducing administrative overhead.
-
Improved Performance: A single core exchange can provide better performance and faster call handling compared to multiple core exchanges.
-
Better Service Quality: A well-organized core exchange can improve service quality by ensuring better trunking, routing, and other aspects of call handling.
How It Works:
-
User Access: Users access the network through a personalized phone number or a mobile number.
-
Call Handling: The core exchange uses the protocol (e.g., VMNP or OSMP) to route calls to the appropriate core exchange or core network.
-
Call Trunking: Calls are transferred to a trunk exchange, where they are further routed to the appropriate core exchange or core network.
-
Text/Call Output: Calls are outputted to the user's device or other devices as needed.
Example:
- A user has a personalized phone number (e.g., +1 (123) 456-789).
- The user connects to the network, and the core exchange handles the call.
- The core exchange uses the protocol (e.g., VMNP) to route the call to the appropriate core exchange.
- The call is outputted to the user's device or other devices.
In summary, an IVPN provides a centralized, efficient, and scalable solution for VoIP services, making it easier to manage and provide quality of service for users.
