Using a mobile terminal ( 2 ) while moving, a user has a voice conversation with a security terminal ( 1 ) provided by a security service provider. This conversation creates a situation in which it is possible to immediately send an alarm if an emergency occurs, thus repelling assaulters or abductors lurking near the user. The mobile terminal ( 2 ) is provided with GPS or the like, and position information of the mobile terminal ( 2 ) is sent to the security terminal ( 1 ). <??>The security service provider takes advertisements from advertisers selling goods or services, and prepares conversation scenarios that are the content of the conversations for automatic response based on those advertisements. The security terminal ( 1 ) firstly provides the user with a voice conversation partner proxy service based on the conversation scenarios and secondly detects emergencies by detecting emergency messages from the mobile terminal ( 2 ) or detecting the interruption of the conversation. After that, the security service provider can restrict the danger to the user to a minimum by undertaking emergency measures such as dispatching someone to the location where the mobile terminal ( 2 ) is located.
