Abstract

Disclosed is an interworking gateway facilitating to-and-fro communication between a first subscriber and a second subscriber. The first subscriber is on a Global System for Mobile Communications Railway (GSM-R) network and the second subscriber is on a Terrestrial Trunked Radio (TETRA) network. In one aspect, the interworking gateway receives a plurality of ISUP messages from the first subscriber. The plurality of ISUP messages are based on an ISUP protocol. Upon receiving an ISUP message, of the plurality ISUP messages, the interworking gateway selects an ISI message, from the plurality ISI messages, equivalent to the ISUP message based on a pre-defined mapping to facilitate the to-and-fro communication. The to-and-fro communication is facilitated by at least one of a Point-to-Point Call (PtP), a Voice Group Call Service (VGCS), and a Voice Broadcast Service (VBS) between the first subscriber and the second subscriber in a vendor independent approach.
