Text messages, that are sent to the DMR or dPMR mobile radio, are transmitted by PIA as POCSAG notification.

PIA – Radio- detector for private mobile radio or individual pager solution

The PIA POCSAG transmitter in VHF or UHF range transmits call- or alarm- signals from the Hytera or icom mobile radio to corresponding pager. In the configuration software, you can adjust the Pager address (RIC) to which the notification is supposed to be transmitted. This can take the form of an individual text message from the mobile radio system or a notification about an incoming call on the radio device.

The optional availabel software for windows offers much  more options: 
With just one POCSAG transmitter you can use the software to send individual messages to different pagers (different RICs). This possibility is especially beneficial for the usage in buildings or on ships, as you can specifically notify different recipients. An intelligent operation of several PIA transmitters also makes it possible to provide comprehensive coverage in buildings or on large company premises.
