Handset makers complete joint specification for 3GPP Push to Talk technology
September 4, 2003
Siemens, Ericsson, Motorola and Nokia announced the completion of a jointly
developed Push to talk over Cellular (PoC) specification based on the
IP Multimedia Subsystem (IMS) as defined by 3GPP. This specification is
intended to reduce marketplace fragmentation and provide end users with
an easy-to-use push to talk experience wherever they may travel in the
world.
Push to talk is basically a wireless service that allows cell phones
to act like long range walkie-talkies.instead of calling someone, you
simply push a button and talk to them. It happens in less than a second,
as with walkie-talkies.Because there's no time spent dialing or making
a connection to a network, calls are shorter and less expensive than usual.
The PoC specification leverages existing 3GPP, OMA, and IETF specifications
making the service easy to integrate in operators’ existing access and
packet core network infrastructures. The PoC specification is a bundle
of six specifications including: Requirements, Architecture, Signaling
Flows, Group/List Management, and two User-plane specifications (Transport
and GPRS).
“End-users want to be able to use any enabled handset on any available
network without having to worry about if they work together. This is true
for all mobile services and push to talk will be no different”, says Torbjörn
Nilsson, Senior Vice President, Marketing and Strategic Business Development
at Ericsson. “The access independent, interoperable, global industry specification
that the major vendors now have agreed on ensures that the end-users will
get this”.
Push to talk is already offered by in North America by Nextel and Verizon
Wireless. Other the US, the technology is still far behind.
