Under the SI conception, any user or content provider has the ability to create public contact groups with special access and quality-of-service rules (Fig. 34). Thus, we can consider any of such a group as a separate virtual network.
Following features of the SI technology provide the user with a freedom to create virtual networks for accessing private communication services and information resources:
- Unrestricted location-based user groping that assumes an indication of the regional public address.
- Unrestricted activity-based user grouping that assumes an indication of the activity-specific public address like an organization or company name.
- Unrestricted interest-based user grouping (social networking) that assumes an indication of the interest group address like “classmates”, “fishers”, “tennis”, etc.
- Ability to provide application of special security, quality-of-service and presence indication rules for any public contact group.
- User’s ability to state a readiness to receive a call on any of known proxy or regional SI servers associating this state and quality-of-service parameters with the interesting user group on the server.
