摘要

PURPOSE: A network discovery method is provided to selectively discover a network in which a device providing a service is formed.;CONSTITUTION: An adjacent device A(200) and an adjacent device B(300) receives a discovery message including a service type information(S14). It is determined whether the adjacent device A and the adjacent device B provide one or more services specified by the service type information(S15a,S15b). When the one or more services specified by the service type information are provided, the adjacent device A transmits the identifier of the formed network to a host(100)(S23).;COPYRIGHT KIPO 2013;[Reference numerals] (100) Host; (200) Adjacent device A; (300) Adjacent device B; (S11a,S11b) Network establishment; (S12a,S12b) Subscription allowance; (S13) Discovery message generation; (S14) Discovery message broadcasting; (S15a,S15b) Is service provided?; (S17) Network selection; (S18) Subscription message; (S19) ID application; (S23) Response message
