This read-create value lets an administrator configure the GPRS QoS precedence class the device will request from the network for this connection. Precedence class determines how the network prioritizes this device's packets relative to other GPRS traffic under congestion, so setting it correctly helps ensure important traffic is not dropped first when the cellular network is busy. For example, an admin provisioning a 3G failover router for critical monitoring traffic could raise this requested precedence so the router's packets are less likely to be discarded than lower-precedence traffic during congestion.
