Problems solved by technology

[0026] Among the four detection technical solutions described above, solutions 1, 3, and 4 mainly solve the scenarios and problems of low-mobility MTC terminals illegally moving under the same SGSN / MME. For cross-SGSN / MME scenarios However, the problem of illegal movement cannot be well solved; for scheme 2, theoretically speaking, regardless of whether the MTC terminal moves across the SGSN / MME, the HSS / HLR has saved the location information of the MTC terminal, which can be reported by comparing the MTC terminal Whether the MTC terminal is moving illegally is determined by whether the information is consistent with the pre-configured information. However, for the comparison of the location information of the low-mobility MTC terminal across SGSN / MME, it must go through the process of identity request, terminal authentication, and location update. If Adopting scheme 2 in the M2M network will cause a huge signaling load to the M2M system

Embodiment 1

[0106] The application scenario of this embodiment is: when the MTC terminal is initially attached, the ASME that the MTC terminal currently requests to access checks whether the MTC terminal is a low-mobility MTC terminal, and if it is, it further determines whether it is in the allowed ASME identification list If it is not present, the MTC terminal is not allowed to access the network. The method for monitoring the position movement of a low-mobility terminal in this embodiment is as follows image 3 As shown, including the following steps:

[0107] Step 301: During initial attach, the MTC terminal sends an initial attach request message to the RAN.

[0108] Step 302: After receiving the initial attach request, the RAN sends an initial attach request message to ASME.

[0109] Step 303: The network and the UE perform AKA authentication and Security mode command procedures.

[0110] Step 304: After the Security mode command process is completed, HSS / HLR sends an insert subscription d...

Embodiment 2

[0121] The application scenario of this embodiment is: the MTC terminal moves, the ASME that provides services to the MTC terminal before the move can identify the identity of the MTC terminal, and has obtained the user subscription data of the MTC terminal from the HSS / HLR, and the MTC terminal currently requests access ASME checks whether the MTC terminal is a low-mobility MTC terminal, and if it is, it further determines whether it is in the allowed ASME identification list, and if not, it does not allow the MTC terminal to access the network. In the following description, the ASME that provides services for the MTC terminal before the move is called Old ASME, and the ASME that the MTC terminal currently requests to access is called New ASME. The method for monitoring the position movement of a low-mobility terminal in this embodiment is as follows Figure 4 As shown, including the following steps:

[0122] Step 401: After the MTC terminal moves, it sends a connection request ...

Embodiment 3

[0139] The application scenario of this embodiment is: the MTC terminal moves, and the ASME serving the MTC terminal before the move cannot identify the identity of the MTC terminal, or the identification message is considered untrusted, or the unique identifier reported by the MTC terminal is a permanent identity identifier, such as IMSI , The ASME that the MTC terminal currently requests to access checks whether the MTC terminal is a low-mobility MTC terminal, and if it is, it further determines whether it is in the allowed ASME identification list, and if not, the MTC terminal is not allowed to access the network. In the following description, the ASME that provides services for the MTC terminal before the move is called Old ASME, and the ASME that the MTC terminal currently requests to access is called New ASME. The method for monitoring the position movement of a low-mobility terminal in this embodiment is as follows Figure 5 As shown, including the following steps:

Abstract

The present invention discloses a method for monitoring the location movement of a low-mobility terminal. The method includes: when a machine-type communication (MTC) terminal accesses a network, the Access Security Management Entity (ASME) that the MTC terminal currently requests to access according to Based on the received location restriction information included in the user subscription data, it is judged whether the location of the MTC terminal has moved. The present invention also discloses a system for monitoring the location movement of low-mobility terminals. By adopting the method and system of the present invention, the location movement of low-mobility terminals can be effectively monitored in a machine-to-machine (M2M) system, and the signal can be reduced. order load.

Description

Technical field [0001] The present invention relates to Machine-to-Machine (M2M, Machine-to-Machine) technology, in particular to a method and system for monitoring the position movement of low-mobility terminals in an M2M system. Background technique [0002] With the emergence and development of global informatization and communication network technology, people can communicate more conveniently and exchange information more and more frequently. However, at present, computers or other intelligent terminal (IT, Intelligent Terminal) devices have networking and communication capabilities only under human intervention, while many ordinary machine type communication (MTC, Machine Type Communication) devices have almost no Networking and communication capabilities. How to make these ordinary machine equipment have networking and communication capabilities so that the communication network technology can better provide services and guarantees for social life and make the city intell...
