4.2. Presence-enhanced services
The basic presence service as we know it today works with the basic idea of "publish–receive" of presence information about humans. Operators have the ability to fetch various infrastructure-related presence attributes, such as location and terminal availability from their communication networks. This enhances the suite of presence information presented to subscribers who subscribe to the operator's presence service and gives the user a greater experience.
New presence-enabled services use presence information in dedicated application areas. This is a big opportunity for innovative companies that want to expand their business. Examples include presence-based call routing as well as network gaming services. In addition, presence creates an alternative advertising and information-sharing channel that the user is comfortable with.
With presence, team working is more efficient, bringing the ability to share information amongst the team members beyond their availability. They can share information such as a meeting location, future plans, etc.
