Nokia will also provide its Presence solution, based on open standards and providing support to PoC as well as many other applications.With push to talk, people can use their mobile phones like walkie-talkies, communicating with a selected group or with individuals at the push of a button. Both business and private users can benefit from a simple and direct communication. Push to talk is especially suited for cases where users need to communicate occasionally but repeatedly with the same group or individual.
Nokia's end-to-end push to talk solution offers a full feature set. It will comply with the upcoming OMA standard and the IP multimedia subsystem standardised in 3GPP, while it will also support various push-to-media, such as video. The company has 39 commercial contracts with GSM operators, and more than 30 operator trials ongoing.
