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 initially attaches, the ASME that the MTC terminal currently requests to access checks whether the MTC terminal is a low-mobility MTC terminal, and if so, further determines whether it is in the allowed ASME identification list , if not, the MTC terminal is not allowed to access the network. In this embodiment, the method for monitoring the location movement of a low-mobility terminal, such as image 3 shown, including the following steps:

[0107] Step 301: when initially attaching, 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 processes.

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

Embodiment 2

[0121] The application scenario of this embodiment is: the MTC terminal moves, the ASME that provides services for 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 so, further determines whether it is in the allowed ASME identification list, and if not, does not allow the MTC terminal to access the network. In the following description, the ASME that provided services for the MTC terminal before moving is called Old ASME, and the ASME that the MTC terminal currently requests to access is called New ASME. In this embodiment, the method for monitoring the location movement of a low-mobility terminal, such as Figure 4 shown, including the following steps:

[0122] Step 401: After the MTC terminal moves, send a Connection Request (Connection Reque...

Embodiment 3

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

Abstract

The invention discloses a method for monitoring the position shifting of a low-mobility terminal. The method comprises the following step that: when a machine type communication (MTC) terminal accesses a network, an access safety management entity (ASME) which the MTC terminal currently requests to access judges whether the position of the MTC terminal is shifted according to received information limiting information contained in user subscription data. The invention also discloses a system for monitoring the position shifting of the low-mobility terminal. After the method and the system which are disclosed by the invention are adopted, the position shifting of the low-mobility terminal can be effectively monitored in a machine-to-machine (M2M) system and a signaling load can also be reduced.

Description

technical field [0001] The present invention relates to a machine-to-machine (M2M, Machine-to-Machine) technology, in particular to a method and system for monitoring the movement of a low-mobility terminal 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 the exchange of information is becoming more and more frequent. However, at present, computers or other intelligent terminal (IT, Intelligent Terminal) devices have networking and communication capabilities only under the condition of human intervention, while many ordinary machine type communication (MTC, Machine Type Communication) devices hardly have Networking and communication capabilities. How to enable these ordinary machine-like devices to have networking and communication capabilities so that communication network technology can better provide services and guarantees for s...
