NETWORK-TO-NETWORK INTERFACE GATEWAY SYSTEM FOR PUSH-TO-TALK-OVER-CELLULAR SERVICE

摘要

A network-to-network interface (NNI) device, including at least one push-to-talk (PTT) interface adapter, a processor connected to the at least one PTT interface adapter, and a non-transitory computer readable medium connected to the processor. The non-transitory computer readable medium has stored thereon instructions that, when executed by the processor, cause the NNI device to receive a first PTT communication in a first PTT format through the at least one PTT interface adapter from a first PTT system, translate the first PTT communication into a second PTT communication in one or more second PTT formats, and transmit the second PTT communication through the at least one PTT interface adapter to one or more second PTT systems
