Embodiments of the present application provide a resource processing method and apparatus, a device, and a storage medium, where the method includes: when a terminal device accesses a network, generating first information including a handover report, and sending the first information, correspondingly, a source network device can receive at least one piece of first information sent by at least one terminal, and each piece of first information includes: a handover report of a corresponding terminal device. Therefore, the source network device can adjust, according to the handover report of the at least one terminal device, a reserved resource allocated by the network device, which further adjusts the coverage and the size of the resource pool reserved for the terminal device in conditional handover, which improves the matching degree between the reserved resources allocated tar the terminal device and the terminal device, solves the problem of resource waste or resource shortage.
