Patent ID: 8051182

Claim:
A communication device as a primary station for communication with a secondary station, the communication 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 communication device comprising a network layer protocol controller, wherein in order to connect to the secondary station, in the network layer, the network layer protocol controller issues a connection request command to the lower layer when the network layer protocol controller has received a connection request command from the upper layer and issues a connection confirmation 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 confirmation command reception notification from the lower layer, when the network layer protocol controller has received a one-way-communication request command from the upper layer, the network layer protocol controller issues a connection request command to the lower layer and thereafter issues a data transfer request command to the lower layer in response to a data transfer request command from the upper layer without waiting for a connection confirmation command from the lower layer.
