Control plane

Definition
A control plane is

"a mechanism used to transmit control information from one system component to another. In the case of mobile devices, a control plane can have multiple forms. Wireless carriers have a control plane built into the operating systems on their devices. The control plane uses specific message formats sent over the cellular network to cause specific behaviors on the mobile device. A MDM also uses a control plane, typically implemented as an IP network or cellular data connection to a device."
