Abstract
A navigation apparatus for displaying a service selection menu on a user terminal so as to navigate a user at the time of selection of a service provider. A traffic obtaining portion obtains band used by each circuit accommodating each service provider from a network controller, and a menu optimizing portion creates a service selection menu which reflects the band used by each circuit accommodating each service provider and displays the menu on a user terminal. When a user selects a predetermined service provider from the service selection menu, a service executing means judges whether or not the user terminal can be connected to the selected service provider, and if connectable, requests a path setting portion to set a path between the user terminal and the selected service provider. The path setting portion connects the user terminal to the selected service provider by an exchange.
