Push to talk over Cellular is an efficient, new way of communication through mobile phones, which benefits both network operators and consumers. PoC enables compatible cell phones to function like two-way radios or 'walkie-talkies' offering one-to-one or one-to-many (group) modes of speech. Thus, it offers users instant connectivity to individuals and groups. It also allows operators to offer a differentiated voice service and more efficient use of network capacity.

LGSI's PoC facilitates the OMA

as it offers PoC for all types of handsets
as new features can be easily adapted
apart from Push to Talk feature, LGSI provides support for instant messaging, presence/publish and browsing from GLMS server.
as efficient algorithm are implemented for compression of signaling

Papers on 'Design and Implementation of the PoC' have been submitted to LGE, Korea for IPR; presentations on the topic have been made by us.
