Method, device and system for accessing machine type communication terminal equipment to network

Abstract

The embodiment of the invention provides a method, a device and a system for accessing machine type communication (MTC) terminal equipment to a network. The method comprises the following steps that: the MTC terminal equipment receives a broadcast message sent from a base station, wherein the broadcast message comprises access control information corresponding to the access control level of the MTC terminal equipment, the access control level of the MTC terminal equipment is different from or equal to that of other types of terminal equipment in the network, and the broadcast message also comprises indication parameter numbers to mark the type of the MTC terminal equipment in the access control level and the other types of terminal equipment in the network; and the MTC terminal equipment judges whether the network can be accessed according to the access control information, and executes corresponding access operation. Through the embodiment of the invention, the access of the MTC terminal equipment can be controlled more flexibly, which is helpful for reducing the probability of network congestion.

Description

technical field [0001] The present invention relates to the field of mobile communication technology, in particular to a method, device and system for machine-type communication terminal equipment to access a network. Background technique [0002] Machine Type Communications (MTC, Machine Type Communications) applications refer to the network communication between one or more network elements without human participation, such as traffic control and management, factory monitoring, remote meter reading and other applications. [0003] Currently, in the existing Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System) network, the user Universal Subscriber Identity Module (USIM, Universal Subscriber Identity Module) card stores access control (AC, Access Control) information, and the network will The AC level stored in the user's USIM card performs access control. In addition, in the Long Time Evolve (LTE, Long Time Evolve) network, it is a...
