Embodiments of the present disclosure disclose a mobility management procedure initiation method and a device, where the method may include: when a quantity N of failures of a mobility management procedure initiated by a device to a core network entity is greater than or equal to a first threshold, determining, by the device, whether N pieces of failure information include first information used to indicate a failure in establishing a radio resource control protocol connection; when the device determines that the N pieces of failure information include the first information, setting, by the device, an initiation condition parameter for initiating the mobility management procedure; and initiating, by the device, the mobility management procedure based on the initiation condition parameter. The present disclosure can improve a network access speed of the device.
