This application relates to a resource management method and an apparatus. The resource management method includes: A network device determines to release or disable one or more uplink resources, where the uplink resources are used to receive uplink data from a terminal device in idle mode. The network device sends first information, where the first information is used to indicate to release or disable a part or all of the one or more uplink resources. The network device may implement relatively flexible management on the uplink resources that are configured for the terminal device and that are used for transmission by the terminal device in idle mode, so that the network device may also schedule the uplink resources when needing to schedule uplink resources.
