Currently, in an internet of things system, the following two methods are mainly used for monitoring the on-off state information and the position information of a terminal by an internet of things platform:
in the first method, an internet of things platform acquires Location information and power on/off state information of a terminal stored in a Home Location Register (HLR), wherein the HLR is a database managed by a user terminal, is used for storing subscription data of a managed terminal and Location information of the terminal, and can provide routing information for a call to a certain terminal.
This method has the following two problems: 1) since only the Mobile Switching Center (MSC) identifier and the general packet radio service support node (Serving GPRS support node, SGSN; general Packet Radio Service (GPRS) identifier, the range of position information is large, and the terminal cannot be accurately positioned; 2) the terminal on-off information cannot be synchronized into the HLR, only after the terminal is powered off for a certain period of time, for example, the terminal is powered off for more than 24 hours, the Visitor Location Register (VLR) can send a clearing (purge) message to the HLR, and the HLR sets a flag that has been cleared (purge) in a record corresponding to the terminal, so that the terminal on-off state information acquired from the HLR is inaccurate, and the real-time on-off state of the terminal cannot be known.
In the second method, because the VLR stores the location information of the terminal, such as the cell identifier (CellID), and the real-time on/off state information of the terminal, the platform of the internet of things sends an instruction to the HLR to instruct the HLR to query the VLR where the terminal is located for the location information and the on/off state information of the terminal
In the method, an HLR is used as important network element equipment, the safety of the HLR is very important, if the HLR is overloaded, the whole network communication is influenced, in order to acquire the on-off state information and the position information of a terminal in time, the on-off state information and the position information of the terminal need to be inquired by the HLR for the same terminal at regular time, the load of the HLR is increased, the processing performance of the HLR is influenced, under the condition of a large-capacity terminal, the load of the HLR is increased seriously, so that a flow control measure has to be taken, a large number of inquiry requests sent by the Internet of things platform need to be abandoned, and the Internet of things platform cannot acquire the on-off state information and the position information of part of the terminal.
