Embodiments of the present invention provide a floor control method and apparatus, so as to resolve a prior-art problem: a control plane and a media plane of a PoC service are not separated, and this causes difficulty in subsequent technology evolution and is not conducive to either flexible implementation of services or system extension; and there is no detailed floor control procedure after the control plane and the media plane are separated. The method includes: receiving, by a media resource function entity, a first floor application message sent by UE; generating, by the media resource function entity, a second floor application message according to the first floor application message; sending, by the media resource function entity, the second floor application message to an MCPTT server; receiving, by the media resource function entity, a first floor grant message that is in response to the second floor application message and that is sent by the MCPTT server; generating, by the media resource function entity, a second floor grant message according to the first floor grant message; and sending, by the media resource function entity, the second floor grant message to the UE.
