Problems solved by technology

[0028] The present invention is proposed to solve the problem in the prior art that the access control of the MTC terminal by the access layer leads to an increase in the complexity of the core network. Therefore, the main purpose of the present invention is to provide an improved M2M terminal access input control schemes to address at least one of the above

Embodiment 1

[0071] In this embodiment, the MTC UE uses the EPS system to achieve access (that is, the MTC UE accesses the E-UTRAN network) as an example for illustration.

[0072] Figure 4 In this embodiment, MTC UE realizes M2M communication by accessing the EPS system, as shown in Figure 4 As shown, in this embodiment, a connection is implemented between the MTC gateway and the MME, and between the MTC gateway and the MTC server, so that the MTC server can obtain information on the underlying access layer / bearer of the MTC UE to determine the behavior of the MTC UE .

[0073] Such as Figure 4 As shown, in the architecture diagram, the MTC GW is deployed in the core network, and the MTC Server may be deployed outside the operator's core network, or may be deployed in the core network. One MTC GW can serve multiple MTC Servers.

[0074]In the architecture diagram, the MTC GW establishes an interface with the MME. For the convenience of description, in this embodiment, the interface...

Embodiment 2

[0081] In this embodiment, an MTC UE accessing a GERAN / UTRAN network is taken as an example for illustration.

[0082] Figure 5 In this embodiment, MTC UE realizes M2M communication architecture through GERAN / UTRAN network access, as shown in Figure 5 As shown, this embodiment is basically similar to the above-mentioned system embodiment 1, the difference is that the SGSN in the GERAN / UTRAN network is equivalent to the MME in the E-UTRAN network, and is used for the access control and mobility management functions of the PS domain. The Gateway GPRS Support Node (GGSN for short) in the GERAN / UTRAN network is equivalent to the SGW and PGW in the E-UTRAN network, and the HLR in the GERAN / UTRAN network is equivalent to the HSS in the E-UTRAN network. Its specific connections and functions of each network element are similar to those of the above-mentioned system embodiment 1, and will not be repeated here.

Abstract

A method and system for controlling Machine Type Communication (MTC) terminal are disclosed by the present invention. Wherein, the method includes the following steps: a mobility management network element reports the information of the MTC terminal, which requests to attach to the network or has attached to the network currently, to an access control network element (S601); the access control network element determines to refuse the MTC terminal access based on the MTC terminal information, and transmits an indication of refusing the access of the MTC terminal to the mobility management network element (S603); the mobility management network element receives the indication, and refuses the MTC terminal to access the network based on the indication (S605). By using the present invention, the access control to the MTC terminal can be realized by the access layer without increasing the complexity of the core network, thus reducing the cost of the network construction.

Description

technical field [0001] The present invention relates to the communication field, in particular, to an access control method and system for a machine type communication terminal. Background technique [0002] In traditional mobile network services, human-to-human (Human To Human, H2H for short) communication occupies a major position. In H2H communication, since the two parties involved are people with the ability to control behavior, the conversation is actually controlled by human behavior. With the development of mobile network services and automation control technology, a new mobile communication method has emerged, that is, Machine To Machine (M2M) communication. In this communication method, the two parties of the communication are machine equipment. . [0003] In a narrow sense, M2M is defined as machine-to-machine communication, but in a broad sense, M2M includes networked applications and services centered on intelligent interaction between machines and terminals. ...
