1. What is a Push to talk service?
Push to talk is an "always-on" service that allows users to call people by pressing just one button. Calls can be made to individuals or groups and the half-duplex (one-way at a time) call connection is almost instant. This meets the diverse needs of business users and private consumers, ranging from controlled team management to spontaneous sharing of experiences.


2. What does the Push to talk over Cellular (PoC) solution mean?
Push to talk over Cellular (PoC) makes Push-to-Talk available through attractive cellular phones. This enhances cellular services and brings new business opportunities in voice communications.

Private consumers can use the terminal to create their own groups, while individual access control lists can be used to control privacy. For business users, an administrator can create closed user groups to maintain company security. Additional features, such as presence, can be included to give further benefits to the user.

PoC is an integral part of the IP Multimedia communication portfolio envisioned by Nokia, and a part of the service offering in the IP Multimedia Subsystem (IMS). It is based on a half-duplex always-on VoIP service over a cellular network.


3. Who are the potential users of PoC?
As PoC benefits a wide range of users, there are many ways to identify user segments. Based on communication needs and behavior, the following segments, for example, can be recognized: small businesses; leisure groups and communities; families, teenagers and social groups; and corporate users. The concept may also interest the most demanding Professional Mobile Radio (PMR) and Land Mobile Radio (LMR) users, but it does not aim to fulfill the stringent requirements of public safety for critical emergency communication.


4. Is PoC a conference call and why half-duplex traffic mode?
Users who use Push to talk traffic are usually doing some other work. They listen to group traffic passively unless they are contacted by their name or they need to say something. Half-duplex traffic is ideal for such uses. For normal conversation, a conventional duplex mode is preferred.

In conference calls many persons can talk simultaneously and a conference bridge adds together and distributes the conference audio to all parties. A conference call is used for example for a business meeting, where people monitor the discussion as their primary task and the call has a specific start and finish time.


5. How does a PoC call take place in practice?
Take this example: John arrives at his hotel and the receptionist, Jane, needs to find a room that the cleaners have finished. Using her phone, she scrolls to the Cleaners group and presses the Push to talk button to ask whether anyone has completed a room. All the cleaners hear the question through the speakers on their phones and Maria uses Push to talk to reply that room 306 is ready.

Jane scrolls to the Porters group and calls for someone to take John's bag. Marco replies that he can be down shortly, but Phil uses Push to talk to say he's already on his way.

John wants to hire a car. Jane makes a normal cellular call to Maggie at the car service and she says she'll reply a.s.a.p. Maggie makes a Push to talk call to her Service Group and Eddie replies that he can be at the hotel in 5 minutes. Maggie lets Jane know using a normal call.

They use it in America you push a button and make a noise and whoever you decided to send it to gets the noise out loud if their push to talk is on, I dont think you can use it in the uk yet though but I cant wait until it comes over because I think its a lot better than text messages, it was on a gadget guide program about 2 years ago, they have them phones in a place I was working a few weeks ago and none of the phones were able to send push to talk.
Here is a motorola ad for it YouTube - Motorola Push-to-talk promotion (http://www.youtube.com/watch?v=Mph6UBZn7qI) .
