Communication Device, Communication System, Communication Method, Communication Program, and Communication Circuit

A communication device as a secondary station for communication with a primary station,

• the device comprising a network layer, an upper layer which is an upper-level communication layer to the network layer, and a lower layer which is a lower-level communication layer to the network layer,
• the device comprising a network layer protocol controller, wherein in order to connect to the primary station, the network layer protocol controller issues a connection request command reception notification to the upper layer, without issuing a data transfer request command to the lower layer, when the network layer protocol controller has received a connection request command reception notification from the lower layer and issues a connection confirmation command to the lower layer when the network layer protocol controller has received a connection confirmation command from the upper layer.

• the device comprising a network layer protocol controller, wherein in order to disconnect from the secondary station, in the network layer, the network layer protocol controller issues a disconnection request command, without issuing a data transfer request command to the lower layer, when the network layer protocol controller has received a disconnection request command from the upper layer and issues a disconnection confirmation command reception notification to the upper layer when the network layer protocol controller has received a disconnection confirmation command reception notification from the lower layer.
