Traditional telecom technologies cannot satisfy these user demands, which led to the recent smartphone boom. The appearance of smartphones has in turn led to the creation of convergent (telecom-IT) solutions. The Rich Communication Suite (RCS), created by leading telecom companies, provides a service portfolio which is rich in functions (for example instant messaging, chat, file transfer, video sharing and text status information), and assists the mining of social information hidden in the user address book. Adherence to standards and uniformity is a very important factor when solutions are implemented, as they can form the basis of additional value-added services. Sophisticated operating systems are needed for using smartphones, therefore these solutions will run on the two mobile platforms (Android and iPhone), which will be probably the most popular ones in the future.

Advantages of solutions created for smartphones:

• Due to corporate demands, the solutions have strong integration features and are linked to email systems and calendar solutions.

• They have several project support functions.

• They provide an enhanced phonebook which contains presence information as well.

• They provide a contact center where the incoming call, using the presence information, is directed to the right professional.

• They provide rich voice call options, such as presence-based call forwarding and barring, or sharing multimedia content during voice calls.

• They facilitate arranging multimedia conference call with multiple participants.

• They provide enhanced messaging options like chat or SMS history.

• Social network services are enhanced with presence information, chat function etc.

Tasks:

• Surveying mobile communication demands.
• Identifying key services.
• Creating value-added services based on an instant messaging and presence platform.
