This read-only value reports the GPRS QoS reliability class actually negotiated with the network, describing the real data-integrity guarantee in effect for this connection. An admin compares it to the requested and minimum reliability settings to confirm the network did not silently grant a less-reliable connection than the application needs. For example, if the negotiated reliability class matches only the device's configured minimum rather than its requested value, the admin knows the carrier barely met the floor and the link may show more retransmissions than hoped.
