Abstract

A contents server fault monitor periodically detects the status of operation of contents servers. Information about the status of operation of the contents servers is held in a server operation database. When an inactive contents server has been detected through look-up of the operation status information, a service menu is prepared that is a list of services which can be provided by active contents servers. Upon a request for the acquisition of a service from a portable terminal, the prepared service menu is sent to the portable terminal. By virtue of this construction, prior to the connection of a portable terminal to a network, a periodically prepared service menu, that indicates only services of contents servers which can provide services, is presented to the portable terminal.
