Abstract

The present specification may provide a method for forming, by a searcher terminal, an application service platform session with an advertiser terminal in a wireless communication system. The method for forming an application service platform session may comprise the steps of: performing discovery for the advertiser terminal and a first service; and forming an ASP session for the first service by performing connection with the advertiser terminal on the basis of a result of the performed discovery, wherein the discovery and the connection may be performed through at least one of multiple interfaces supported by application service platforms of the searcher terminal and the advertiser terminal when the searcher terminal and the advertiser terminal are first type terminals, and the discovery and the connection may be performed through a Wi-Fi direct interface when one of the searcher terminal and the advertiser terminal is the first type terminal and the other is a second type terminal.

Claims6

Dependent claims

A method for forming, by a seeker device, an application service platform (ASP) session with an advertiser device in a wireless communication system, the seeker device operating based on an ASP supporting a plurality of interfaces and the method comprising:

paging a SeekService method including a service name, wherein a service name format is mDNS (Multicast Domain Name System) format;
after paging the SeekService method, changing the service name format to Wi-Fi interface format based on mapping tables when a service is supported only in the Wi-Fi interface,
wherein the mapping tables are used to change between Wi-Fi Direct Service (WFDS) service names and corresponding mDNS service names,
converting the service name to a service hash value using a hash algorithm;
performing discovery restrictively for only a specific type of advertiser device associated with the service name format using the service hash value,
wherein the specific type of advertiser device is a first type advertiser device or a second type advertiser device,
wherein the first type advertiser device is a device operating based on an ASP supporting the plurality of interfaces, and
wherein the second type advertiser device is a device operating based on an ASP supporting a Wi-Fi direct interface only,
forming the ASP session for the service by performing connection with the first type advertiser device on a basis of a result of the performed discovery, based on any one of the plurality of interfaces supported by ASPs of the seeker device and the first type advertiser device, when the service name format is the mDNS format;
and
forming the ASP session for the service by performing connection with the second type advertiser device on the basis of the result of the performed discovery, based on the Wi-Fi Direct interface, when the service name format is changed to the Wi-Fi Direct interface format.

8 more elements

A seeker device for forming an application service platform (ASP) session with an advertiser device in a wireless communication system, the seeker device comprising:

a receiver for receiving information from an external device;
a transmitter for transmitting information to the external device;
a processor for controlling the receiver and the transmitter and operating based on an ASP supporting a plurality of interfaces,
wherein the processor:
pages a SeekService method including a service name, wherein a service name format is mDNS (Multicast Domain Name System) format;
after the pages the SeekService method, changes the service name format to Wi-Fi interface format based on mapping tables when a service is supported only in the Wi-Fi interface,
wherein the mapping tables are used to change between Wi-Fi Direct Service (WFDS) service names and corresponding mDNS service names,
converts the service name to a service hash value using a hash algorithm;
performs discovery restrictively for only a specific type of advertiser device associated with the service name format using the service hash value,
wherein the specific type of advertiser device is a first type advertiser device or a second type advertiser device,
wherein the first type advertiser device is a device operating based on an ASP supporting the plurality of interfaces, and
wherein the second type advertiser device is a device operating based on an ASP supporting a Wi-Fi direct interface only,
forms the ASP session for the service by performing connection with the first type advertiser device on a basis of a result of the performed discovery, based on any one of the plurality of interfaces supported by ASPs of the seeker device and the first type advertiser device, when the service name format is the mDNS format;
and
forms the ASP session for the service by performing connection with the second type advertiser device on the basis of the result of the performed discovery, based on the Wi-Fi Direct interface, when the service name format is changed to the Wi-Fi Direct interface format.
