The present invention relates to data or signaling techniques for controlling machine type communication (MTC) devices, and more particularly to a method and system for controlling signaling or data transmission of machine type communication devices. Background technique

FIG. 1 is a schematic structural diagram of a cellular wireless communication system. As shown in FIG. 1 , a cellular wireless communication system is mainly composed of a core network (CN, Core Network), an access network (RAN, Radio Access Network), and a terminal. The core network is responsible for non-access layer transactions such as terminal location updates, etc. The core network is also the anchor point of the user plane. The access network includes a base station, or a base station and a base station controller, and the access network is responsible for access layer transactions, such as management of radio resources. The base stations may have physical or logical connections according to actual conditions, such as the base station 1 in FIG. And the connection between the base station 2, the base station 1 and the base station 3, and each base station can be connected to more than one core network node. A user equipment (UE, User Equipment) refers to various devices that can communicate with a cellular wireless communication network, such as a mobile phone or a notebook computer.

The MTC service is a service in which machines communicate with machines. In the MTC service, no human participation is required. All communication is performed by the machine. The MTC service obtains data through a sensor or the like, and then reports the data to the mobile communication network through the communication module, and accesses the public data through the mobile communication network. The network can be applied to logistics monitoring, safety monitoring, telemedicine testing, remote meter reading, etc. This data is managed by the mobile operator or a specific MTC operator's specific server and can be viewed by MTC users or MTC managers. In this process, the device that acquires the data required by the service is the MTC device.

The MTC service introduces some features that are different from traditional mobile communications, such as time control features. When this feature is activated, the MTC device only allows signaling or data to be sent within a specified time. When the MTC user subscribes to an MTC device, the operator sets and activates the Time Controlled feature in the subscription information of the MTC device and stores it in the Home Subscriber Server (HSS). The HSS is an entity in the telecommunication network that is responsible for storing identity information, authentication information, and authorization information of a user or a terminal device. Depending on the situation, the HSS can be used to store the user's identity information and the binding information of the user and the terminal device, or only the identity information of the user (the gateway can save the binding information of the user and the terminal device), or directly save the identity of the terminal device. information. The HSS is also responsible for the user's subscription database, as well as the user's authentication and authorization. The service platform can query user or terminal information from the HSS.

Mobility Management Entity (MME, Mobility) when the MTC device is attached to the network

Management Entity) Obtain the contract information of the MTC device from the HSS and save it locally. The MME is an entity used to manage user terminal control signaling in the core network, and is responsible for access control, including authentication control, identification (such as Global Unique Temporary Identifier (GUTI), and Location I (TAI). Tracking Area Identify ) ), user identification and device identification verification, signaling plane encryption, consistency protection with eNB, security parameters between 2G/3G and EPS, and quality of service (QoS) parameters Conversion, access admission control, decision whether to obtain the requested resources and reserve these resources, lawful interception, mobility management (to achieve tracking and recording of the current location of the UE), session management, for the evolved packet system (EPS, Evolved Packet) System) related operations, as well as network element selection.

For the time control feature of the MTC, the network is required to control the control of the MTC device access request or data transmission and reception, that is, the signaling or data outside the specified time, the network should be able to reject, and only receive or process the signaling within the specified time. Or data.
