Abstract

Proposed is a method for receiving a Wi-Fi service by a wireless LAN station supporting an application service platform (ASP). Specifically, the Wi-Fi service can be received through at least two connection techniques, for example, a Wi-Fi direct connection of Wi-Fi infrastructure connection may be used. The wireless LAN station having an ASP may detect information on each of the connection techniques and may be provided with the Wi-Fi service using one of the connection techniques. In addition, when a change in a communication environment or the like occurs, the connection technique may be switched and, in this case, signaling for switching the connection technique may be used.

First claim

What is claimed is:

1. A method for receiving a Wi-Fi service in a wireless LAN station supporting an application service platform (ASP), comprising:
receiving, by the ASP, a first seek service message and acquiring information on a wireless LAN station providing the Wi-Fi service through a Wi-Fi direct connectivity by using the first seek service message;
receiving, by the ASP, a second seek service message and acquiring information on a wireless LAN station providing the Wi-Fi service through a Wi-Fi Infrastructure connectivity by using the second seek service message;
selecting any one of the Wi-Fi direct connectivity and the Wi-Fi Infrastructure connectivity, based on the information acquired by using the first seek service message and the second seek service message, and receiving the Wi-Fi service by using the selected connectivity; and
determining whether or not to receive the Wi-Fi service through a connectivity that is different from the connectivity selected between the Wi-Fi Direct connectivity and the Wi-Fi Infrastructure connectivity.

2. The method of claim 1 , further comprising:
transmitting a message requesting a change in the connectivity, in case the Wi-Fi service is received through a connectivity that is different from the selected connectivity.

3. The method of claim 2 , wherein the message requesting a change in the connectivity further comprises:
information related to a wireless LAN station providing the Wi-Fi service through the Wi-Fi Infrastructure connectivity, or information related to a wireless LAN station providing the Wi-Fi service through the Wi-Fi Direct connectivity.

4. The method of claim 3 , wherein the information related to a wireless LAN station providing the Wi-Fi service through the Wi-Fi Infrastructure connectivity corresponds to a MAC address of a wireless LAN station providing the Wi-Fi service through the Wi-Fi Infrastructure connectivity, and
wherein the information related to a wireless LAN station providing the Wi-Fi service through the Wi-Fi Direct connectivity corresponds to a MAC address of a wireless LAN station providing the Wi-Fi service through the Wi-Fi Direct connectivity.

5. The method of claim 1 , wherein the acquiring information on a wireless LAN station providing the Wi-Fi service through a Wi-Fi Direct connectivity comprises:
transmitting a probe request message by using information included in the first seek service; and
receiving a probe response message corresponding to the probe request message.

6. The method of claim 1 , wherein the acquiring information on a wireless LAN station providing the Wi-Fi service through a Wi-Fi Infrastructure connectivity comprises:
configuring an IP packet by using information included in the second seek service and transmitting the configured IP packet.

7. The method of claim 1 , wherein the information related to a wireless LAN station providing the Wi-Fi service through the Wi-Fi Infrastructure connectivity comprises:
a MAC address of a wireless LAN station providing the Wi-Fi service through the Wi-Fi Infrastructure connectivity, and
identification information of an access point (AP) providing the Wi-Fi Infrastructure connectivity.

8. The method of claim 1 , wherein the Wi-Fi Direct connectivity corresponds to a connectivity scheme providing connectivity between wireless stations without using an access appoint (AP), and
wherein the Wi-Fi Infrastructure connectivity corresponds to a connectivity scheme providing connectivity between wireless stations by using an AP.

9. A wireless LAN station, comprising:
a radio frequency (RF) unit transmitting and receiving radio signals; and
a processor unit being connected to the RF unit and supporting an application service platform (ASP),
wherein the processor is configured:
to receive a first seek service message and to acquire information on a wireless LAN station providing the Wi-Fi service through a Wi-Fi direct connectivity by using the first seek service message,
to receive a second seek service message and to acquire information on a wireless LAN station providing the Wi-Fi service through a Wi-Fi Infrastructure connectivity by using the second seek service message,
to select any one of the Wi-Fi direct connectivity and the Wi-Fi Infrastructure connectivity, based on the information acquired by using the first seek service message and the second seek service message, and to receive the Wi-Fi service by using the selected connectivity, and
to determine whether or not to receive the Wi-Fi service through a connectivity that is different from the connectivity selected between the Wi-Fi Direct connectivity and the Wi-Fi Infrastructure connectivity.

10. The LAN system of claim 9 , wherein the processor is configured to transmit a message requesting a change in the connectivity, in case the Wi-Fi service is received through a connectivity that is different from the selected connectivity.

11. The LAN system of claim 10 , wherein the message requesting a change in the connectivity further comprises:
information related to a wireless LAN station providing the Wi-Fi service through the Wi-Fi Infrastructure connectivity, or information related to a wireless LAN station providing the Wi-Fi service through the Wi-Fi Direct connectivity.

12. The wireless LAN of claim 11 , wherein the information related to a wireless LAN station providing the Wi-Fi service through the Wi-Fi Infrastructure connectivity corresponds to a MAC address of a wireless LAN station providing the Wi-Fi service through the Wi-Fi Infrastructure connectivity, and
wherein the information related to a wireless LAN station providing the Wi-Fi service through the Wi-Fi Direct connectivity corresponds to a MAC address of a wireless LAN station providing the Wi-Fi service through the Wi-Fi Direct connectivity.
