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

The invention discloses a method and system for access control of a machine type communication (MTC) terminal. In the access control method, firstly, a mobility management network element (MMNE) reports MTC terminal information currently requesting to be adhered to a network or currently adhered to the network to an access control network element (NE); the access control NE judges that the MTC terminal is not allowed to access in accordance with the MTC terminal information, and then sends an instruction of refusing the MTC terminal to access to the MMNE; and the MMNE receives the instruction, and refuses the MTC terminal to access to the network in accordance with the instruction. According to the access control method, only the MTC Server which is allowed to access to the network can access to a core network, and an illegal MTC Server is refused to access to the core network, thus ensuring the safety of the core network.

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. ...
