Abstract
A method, a mobility management unit and a gateway unit for restricting access and communication of a machine type communication (MTC) device are provided by the present invention. The method includes: a mobility management unit judging whether an access request or a service request of the MTC device is currently in a permission period according to the permission period of the MTC device; when the access request or the service request is not in the permission period, rejecting the access request or service request of the MTC device and notifying the MTC device of the rejection cause and/or the permission period at a meantime. The present invention can ensure that the MTC device only communicates in the permission period, and the MTC device is restricted to access the network or communicate in the non-permission period according to the requirement of the operator.
