Detailed Description
The principles and spirit of the present invention will be described below with reference to several exemplary embodiments, which should be understood to be presented only to enable those skilled in the art to better understand and implement the present invention, and not to limit the scope of the present invention in any way. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
As will be appreciated by one skilled in the art, embodiments of the present invention may be embodied as a system, apparatus, device, method, or computer program product. Accordingly, the present disclosure may be embodied in the form of: entirely hardware, entirely software (including firmware, resident software, micro-code, etc.), or a combination of hardware and software.
According to the embodiment of the invention, a radius record which can be sent to be on-line is accessed on a PGW by a terminal, the record comprises MDN (minimization of mobile telecommunication number), IMEI (international mobile equipment identity) information and the like, a normal terminal can be constructed to be put in storage through on-line, updating and off-line records, and IMEI (international mobile equipment identity), MDN (minimization of mobile telecommunication number) and access time data of the terminal are mainly stored. After the internet of things terminal is bound to a subscriber identity module card for preventing theft, if the HSS is accessed by other terminals, the HSS sends the IMEI information of the current access terminal, but the information sending is triggered only once, so that the final access time needs to be updated by attaching the DPI signaling information. And the memory base is used for storing the terminal accessed by the MDN and the access time as the basis for judging the subsequent data. And judging whether the MDN exists or not according to the MDN and the IMEI, if the MDN does not exist, adding the MDN, if the MDN exists, judging according to the access time, and if the MDN exists, updating the MDN, and if the MDN exists, adding the MDN, otherwise, judging according to the access time, and if the data time is greater than the recording time in the memory bank, updating the MDN.
The principles and spirit of the present invention are explained in detail below with reference to several representative embodiments of the invention.
Fig. 1 is a schematic flow chart of a method for constructing an internet of things terminal history library according to an embodiment of the present invention. As shown in fig. 1, the method includes:
step S100, radius data docking and analyzing: in the 4G network, if the terminal of the Internet of things is accessed to the online, the PGW sends the radius records of the online, the updating and the offline of the user, and the radius records can be sent to a receiving server through configuration; the receiving server can distribute the radius records by deploying the LVS, because the number of the internet of things terminals accessed to an operator is hundreds of millions, and the number of the radius records at the second level can reach tens of thousands, the message server and the message queue need to be flexibly deployed at the rear end of the LVS, the radius records are distributed by the LVS, and the radius records are written into the message queue by the flux middleware deployed in the application server; and the analysis server at the rear end reads radius records from the message queue for analysis.
Taking the online record as an example, the radius record includes the following data information: event time, MDN, IMSI, IMEI, location information, status type, and access APN, etc.
Step S101, butt joint of the information of the IMEI of the HSS: the Internet of things terminal user needs to sign a contract for machine card binding to prevent the terminal from being stolen, and one card can only be used on the bound terminal; the machine-card binding information signs a contract on the HSS, if the card is used by other terminals, a notification message is triggered, and the current abnormal terminal MDN, IMSI, IMEI, event time and position information are reported to the server.
Meanwhile, DPI data is also required to be docked to process attachment request signaling data, and only the data with attachment failure is filtered; after the attachment is successful, the bearer establishment is carried out to trigger radius reporting, so that the part only needs to process the data failed in the attachment; performing IMEI recording on the abnormal access condition; the DPI attachment failure record is only used as a supplement of the abnormal data of the machine-card binding.
Step S102, abnormal access data storage of a terminal history library: the storage fields in the history library are mainly as follows: MDN, IMSI, IMEI, initial access time of the terminal, final access time of the terminal, position information and state; if the HSS IMEI reports the abnormal record, whether the MDN and the IMEI exist in a memory bank as the main key is judged, and if yes, the terminal last access time is refreshed; if the primary key does not exist in the memory library, the new terminal is used for access, the state accessed into the terminal history library is abnormal, and the abnormal IMEI and the event of the MDN are updated.
The abnormal record reported by the HSS IMEI is mainly used for constructing a terminal abnormal library, and the DPI attachment failure record is used for updating the last access time of the abnormal terminal; the DPI attachment failure record can be obtained by judging whether the MDN and the IMEI exist in a memory bank or not, if so, updating the last access time, and otherwise, discarding the data.
Step S103, normal access data storage of the terminal history library: the normal access terminal history library is mainly constructed by using radius records, and the state is normal. Updating the last access time if the MDN and the IMEI in radius records exist in the memory bank and the event time is greater than the recorded time; and if the current data does not exist, inserting the current data into a database as a new record, and updating the last access time of the last normally accessed data into the event time of the current data.
The whole life cycle of the terminal access of the Internet of things can be recorded by constructing a normal terminal library and an abnormal terminal library; different terminals make a decision based on the IMEI and the first eight bits of the IMEI can be matched through a library of modules to correlate terminal type (e.g., handset, tablet and handheld terminal) and detailed model.
Step S104, abnormal terminal identification: for the abnormal record reported by the HSS IMEI, directly judging that the state of the terminal is abnormal; for other normal state records, if the terminal and the access position are changed, a judgment rule is triggered, the judgment rule is a predefined access terminal IMEI and installation position, for example, the predefined terminal IMEI is XX, the installation position is XX cell, the IMEI and the position reported at present are inconsistent with the predefined one, the terminal is considered abnormal, the terminal is marked as abnormal change, and then an enterprise manager judges whether the terminal is abnormal or not.
Step S105, terminal life cycle inquiry and diagnosis: after the terminal history library is constructed, the terminal history library is required to be provided with external interface capability, and the following interface capability is mainly provided: inquiring the accessed terminal history record through the card number, inquiring the accessed card number history record through the IMEI of the terminal and judging whether the card number is accessed by an abnormal terminal.
