vSEPP visited network’s security proxy
However, I can provide some insights into what "visited network's security proxy" might refer to based on general concepts in networking and security:
Visited Network's Security Proxy:
In the context of mobile networks or roaming scenarios, when a mobile user (subscriber) moves from their home network (originating network) to a different network (visited network) outside their home service area, certain security measures may be put in place to ensure secure communication and protect the interests of both the home network and the visited network.
One way to achieve this is by using a concept called "visited network's security proxy" or "visited network's security gateway." This entity acts as an intermediary between the visited network and the home network, facilitating secure communication and ensuring that the user's data and traffic are appropriately handled.
Key Functions and Components:
- Authentication and Authorization: When a mobile user roams into a visited network, the visited network's security proxy is responsible for authenticating the user and obtaining authorization from the home network to grant access to specific services and resources.
- Traffic Tunneling and Encryption: To ensure secure communication between the mobile user's device and the home network, the visited network's security proxy may establish a secure tunnel through which the user's data traffic is routed. This tunnel is often encrypted to protect data from eavesdropping and unauthorized access.
- Traffic Filtering and Policy Enforcement: The security proxy may enforce security policies and filtering rules defined by the home network. This helps maintain consistency in security measures, even when the user is connected to a different network.
- Billing and Charging: In roaming scenarios, the visited network's security proxy may play a role in billing and charging. It may collect usage information and forward it to the user's home network for billing purposes.
