AT commands on RM500Q-GL to ping gNB in a terminal


We integrated our modem into a 5G standalone network based on OpenAirInterface. We open PDU session and register the modem/UEwith the 5G core, retrieve modem ip address which can be ping successfully ping from the Core. Now we are looking for pinging the gNB from the modem RM500Q.

Therefore, is there any new AT command to perform the ping toward the core (as the old AT+QPING is not available anymore)?

Does anyone know if there is a way to ping the core?
