Abstract
An apparatus for providing information about an available service using a proxy server and a method thereof.

An apparatus for providing information about an available service using a proxy, the apparatus comprising:
- a base station for a wireless network or a proxy server in a local area network, the base station or proxy server including:
- a database configured to store available service information and received information about registration of subscription;
- an available service checker configured to receive, from a user, available service query data that contains a service ID;
- compare the received data with available service data;
- in response to a comparison result indicating that a corresponding service is present, generate and transmit to the user available service response data that comprises information about a service corresponding to the service ID;
- and in response to a comparison result indicating that the corresponding service is not present, transmit the information about registration of subscription which is generated by subscribing to and registering a service corresponding to the service ID;
- an available service searcher configured to transmit service discovery query data associated with the subscribed service corresponding to the service ID, obtain available service data from received service discovery response data regarding a service providing device and whether or not the service providing device provides the service corresponding to the service ID of the service discovery query data, and transmit the obtained available service information;
