Facilitating communication between cellular and digital mobile radio devices is presented herein. In one aspect, a digital mobile radio messaging gateway is deployed within a cellular network that allows cellular devices to send and/or receive data to digital mobile radio devices. Moreover, the digital mobile radio messaging gateway provides transparent messaging access from devices to digital mobile radio switches and/or gateways essentially making the cellular network an extension of the digital mobile radio network. As an example, the digital mobile radio messaging gateway converts data received from the digital mobile radio network to a message that conforms to a protocol supported by the cellular network. Similarly, the digital mobile radio messaging gateway converts data received from the cellular network to a message that conforms to a protocol supported by the digital mobile radio network.
