Ericsson, Nokia and Siemens have joined forces to promote a unified solution for push-to-talk solutions over GPRS and EDGE networks, based on the IP Multimedia Subsystem.
Aiming to provide an alternative to numerous proprietary solutions from smaller players, Ericsson, Nokia and Siemens are now teaming up to define specifications for an open standard to speed the adoption of direct-call push-to-talk service over GPRS. The technology uses the capabilities of the IP Multimedia Subsystem (IMS) as specified by 3GPP for enabling IP connections between mobile phones, and initial trials are expected to begin in the second half of 2003.
IP Multimedia System (IMS) is a technology standardized by 3GPP, broadly viewed as a key development of the mobile communication into IP technologies by adding the ability to deliver integrated voice and data services over the IP-based packet switched network, using SIP to initiate a session.
The three manufacturers said specifications created through this collaboration will be submitted to relevant industry bodies in order to create a standard that will avoid fragmentation. In doing so, they hope to establish a unified push-to-talk over GPRS market with the same economies of scale that made GSM a global success, and to let mobile phones and networks be used for push to talk communication using a variety of radio access networks.
Ericsson, Nokia and Siemens are also inviting mobile network operators and other manufacturers to join them in creating an open, multi-vendor market for push to talk in the GSM evolution path (GSM/GPRS/EDGE/WCDMA) by developing products and services based on the open standard the three are currently attempting to define.
