Abstract
A service discovery method and a service discovery apparatus enable a NAN device that does not support a multi-hop service discovery not to respond to a relayed multi-hop service discovery message on the premise that the relayed service discovery message is correctly received by a NAN device that supports the multi-hop service discovery. The method includes: receiving, by a second NAN device, a first service discovery message that is sent by a first NAN device and that is used for a service discovery; and generating, by the second NAN device based on the first service discovery message, a second service discovery message used for the service discovery, and sending the second service discovery message, where the second NAN device serves as a service relay device that relays the service discovery initiated by the first NAN device.
