Abstract

The embodiment of the invention discloses an access control method for machine type communication, equipment and a communication system. In one scheme provided by the embodiment of the invention, a mobility management network element transmits the access control information of a machine type communication (MTC) terminal set to access network equipment; and when receiving a message from an MTC terminal belonging to the MTC terminal set in a radio resource control connection establishment process, the access network equipment performs access control on the MTC terminal belonging to the MTC terminal set according to the access control information of the MTC terminal set. By the scheme, the access control such as access grant, access prohibition, access delay and the like over given or all the MTC terminals can be realized, thereby effectively reducing the probability of occurrence of signaling congestion of core network nodes and further improving the risk resistance of a network.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an access control method and equipment for machine type communication and a communication system. Background technique [0002] Machine Type Communications (MTC, Machine Type Communications) refers to the network communication between one or more network elements without human participation, such as traffic control and management, remote meter reading, remote monitoring, mobile payment, Location tracking, medical monitoring and other applications. [0003] The MTC service will accelerate the growth rate of the number of wireless communication terminals. The huge number of terminals is a huge challenge to the wireless communication network, and the wireless communication network is required to be scalable to adapt to the huge number of terminals and related new requirements. . [0004] In the 3rd Generation Partnership Project (3GPP, 3rd Generation Partnership Project) co...
