摘要

A communication device and a method for controlling a communication device that can load or unload service information at appropriate timings by flexibly designating discriminating conditions of connection or disconnection of a link. A service manager reads out necessary service information, such as service program or driver software, from the information memory area based on discriminating conditions designated in communication controlling information of the communication status. The service manager loads service information to a temporary information memory area in a host device. The service manager also unloads unnecessary service information from the temporary information memory area in the host device. A connection manager then performs communication protocol for communicating between the service information loaded in the temporary information memory area of the host and the service information memory of the device side.
