Abstract

Traditional Push To Talk (PTT) service has been available for decades but only recently new Internet Protocol (IP) based specifications for Push to talk over Cellular (PoC) utilizing legacy cellular packet data bearers have been introduced. Lead market implementation of PoC is already ongoing but the commercialization process still includes many technical and market risks. The PoC technology has a potential to create new mobile service evolution path starting from voice and extending later on to other group applications. This paper discusses strategic actions related to standardization, system architecture, vendorsý product strategies, substitutes, regulation and service provision in order to advance service diffusion of PoC.
