Registration of electronic device to server

摘要

When a user management server apparatus transmits session information to a user terminal apparatus operated by a user, and receives the session information from an electronic device via a network, the user management server apparatus registers a correspondence relationship between the user who operates the user terminal apparatus and the electronic device. A temporary registration server apparatus receives the session information from the user terminal apparatus and transmits the session information and address information on the network of the user management server apparatus which should be a transmission destination of the session information to the electronic device.
