Embodiments of the present invention provide a service information discovery method and device. The method includes: sending a first query request message, where the first query request message carries a first hash value, and the first hash value is obtained by performing a first hash operation on service identity information of a service to be discovered; receiving a first query response message sent by a peer end, where the first query response message carries first result notification information, and the first result notification information is used to identify whether a service of which a hash value obtained by performing the first hash operation is the first hash value exists at the peer end; and determining, according to at least the first result notification information, whether the service to be discovered exists at the peer end. By using the technical solution of the present invention, a length of a query request message or a service information indication message in a service discovery process may be reduced, and channel resources occupied by those messages may be reduced, which helps to improve utilization of channel resources. |
