818 — Mobile industry leaders complete joint specification for 3GPP

Sep 10, 2003 | Conteúdos Em Ingles

Mobile phone industry leaders Ericsson, Motorola, Nokia and Siemens mobile announced today 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. It was completed to meet a tremendous market interest in push to talk and IMS.

“Standards lead to services transparency in the eyes of the customer and that is the route to widespread adoption. Just as we saw with the interoperability of SMS, the ability for one customer to interact with another, without regard to their service provider, will be key to the success of this service,” said Bill Clift, chief technology officer – Cingular Wireless. “This is an important step in that direction.”

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, signalling flows, group/list management, and two user-plane specifications (Transport and GPRS ).

Ericsson, Motorola, Nokia and Siemens Mobile formed this PoC ‘technology co-operation’ to produce a joint, fast track technology proposal “to provide mobile operators with the assurance of easy integration, global interoperability and a competitive handset environment in the mobile communications market”. The companies have submitted this specification to the Open Mobile Alliance (OMA) standards body for review as a baseline to provide an access-independent and globally interoperable standard for PoC.
