According to an embodiment, an application server (AS) of the IMS receives from a terminal device a first request for initiating a call service and an internet service which are to be integrated with each other. The AS of the IMS sends a second request for initiating the internet service to a gateway server that acts as a gateway to an internet AS capable of providing the internet service. In response to a reply from the gateway server, the AS of the IMS handles the first request based on the reply.
