Method, device and system for acquiring terminal switch status and location information

Abstract

The invention discloses an acquisition method and system for terminal turning-on and tuning-off state and location information and equipment. The acquisition method and system for terminal turning-on and tuning-off state and location information and equipment are used for acquiring the accurate terminal turning-on and tuning-off state and location information under the premise that less load is added on network equipment. The acquisition method comprises the steps that the address of switching equipment accessed by a terminal saved locally at present is acquired by epcglobal network platform equipment, and the address of the switching equipment is sent by a HSS or a HLR after being altered at the terminal position; inquiring request on the terminal turning-on and tuning-off state and location information is sent by the epcglobal network platform equipment according to the address, and the terminal turning-on and tuning-off state and location information sent back by the switching equipment is received by the epcglobal network platform equipment.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for acquiring information on the on / off status and position of an Internet of Things terminal. Background technique [0002] The Internet of things (The Internet of things) is an important part of the new generation of information technology. Combined to form a huge network. [0003] At present, in the Internet of Things system, the Internet of Things platform mainly has the following two methods for monitoring the on-off status information and location information of the terminal: [0004] In the first method, the Internet of Things platform obtains the location information and on / off state information of the terminal stored in the home location server (Home Location Register, HLR), wherein, the HLR is a database managed by the user terminal, which is used to store the information of the terminal under its jurisdiction.

Problems solved by technology

[0005] There are following two problems in this method: 1) because there are only the Mobile Switching Center (MobileSwitching Center, MSC) identification and General Packet Radio Service Support Node (Serving GPRS SupportNode, SGSN; General Packet Radio Service, GPRS) identification where terminal is located in HLR , the location information range is large, and it is impossible to accurately locate the terminal; 2) The terminal power-off information cannot be synchronized to the HLR. ) can send a purge message to the HLR, and the HLR will set a purged flag in the corresponding record of the terminal. Therefore, the terminal’s on / off status information obtained from the HLR is inaccurate, and the terminal cannot be known The real-time switch status of

[0007] In this method, the HLR is an important network element device, and its own security is very important. If the HLR is overloaded, the communication of the entire network will be affected. A terminal needs to periodically go to the HLR to query the terminal's on / off status information and location information, which increases the load on the HLR and affects the processing performance of the HLR. Without traffic control measures, a large number of query requests sent from the IoT platform need to be discarded, resulting in the IoT platform being unable to obtain the on / off status information and location information of some terminals
