Abstract: There is provided a network connection management system which is capable of performing control of connection or access to a network easily without requiring a dedicated device. A user wishing to access an information server apparatus uses a portable communication terminal to send ID information and location information. ID information of the user, location information of major accessible places, and access levels based upon the ID information, the location information, and time information are stored in the information server apparatus in advance. The information server apparatus sends connection permission information, which is based upon the ID information and the location information of the user, to the terminal. Upon receiving the connection permission information in the terminal, the user makes connection to the information server apparatus from an information processing apparatus via a communication network based upon the connection permission information and carries out jobs or the like.
