Method, mobile management unit and gateway for restricting MTC device to access and communicate

摘要

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.
