On the wave of the success in the wire-line world, IP technology is going to play a dominant role even in the wireless scenarios. In a few years, more people are going to access the Internet from mobile phones, personal digital assistants (PDAs) and smartphones and not only for accessing business applications. A wide variety of old and new services are going to be accessible from mobile terminals like instant messaging, video streaming, infocommercial and infotainment applications, games, only to make a few examples. With the development of 3rd Generation (3G) wireless systems, operators are expecting to make new revenue from data services. In this scenario, push technology combined with location and presence services is expected to have a relevant role as enabler of new service features and new service paradigms. Challenging applications of infotainment and infocommercial provided by mobile operators and third parties can be empowered by push platforms integrated in the mobile network. This paper introduces the concept of enhanced push services and discusses architectural solutions for the provision of push based services.
