Abstract: Embodiments of the present invention provide an information query method and device, which can reduce a waste of resources in an information query process, and decrease power consumption. The method includes: sending, by a requesting device in a broadcast manner, a first query request message, where the first query request message carries a first query condition and information about a group identity; and when the requesting device receives a first query response message sent by a responding device that meets the first query condition, sending, by the requesting device, a second query request message that uses the group identity as a receiving address, so that the responding device processes the second query request message.
