Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. It will be apparent that the described embodiments are some, but not all, embodiments of the invention. All other embodiments, which are obtained by a person skilled in the art based on the described embodiments of the invention, fall within the scope of protection of the invention.
In the related art, there are two technical schemes that can realize the base station positioning of the mobile communication terminal:
scheme one: the Location information of the mobile communication terminal accessing the mobile communication network base station is obtained through a special Location platform of the mobile communication system, namely a Location-service platform (Location-based services platform, LSP), a cooperative mobile communication system core network element home Location register (Home Location Register, HLR)/home subscriber server (Home Subscriber Server, HSS), a mobile switching center (Mobile Switching Center, MSC)/mobility management entity (Mobility Management Entity, MME), a visitor Location register (Visiting Location Register, VLR) and the like. The scheme can be used for positioning the terminal base station through the background of the mobile communication system, and is free from terminal support and perception. However, this solution is inefficient because of the long flow and the large number of involved network elements, and the average duration of each positioning request is 1500ms. And only support terminal-by-terminal to perform base station positioning, the system concurrency is 500, and a large number of terminals are not supported to perform base station positioning at the same time, so that tens of thousands to hundreds of thousands of terminal position information of the internet of things cannot be obtained in batches at the same time. In addition, the scheme relies on the cooperation of a special positioning platform of a mobile communication network and core network elements HLR/HSS, MSC/MME and VLR, and if the capacity is required to be expanded, the capacity expansion and upgrading of a plurality of network elements are involved, so that the investment is huge.
Scheme II: the platform pre-deposits (or pre-stores) the mobile communication system base station ID and the corresponding database of longitude and latitude thereof. The terminal actively reports the base station ID of the terminal access mobile communication network to the platform. The platform queries a database through the base station ID reported by the terminal to obtain the positioning of the terminal base station. The scheme can perform batch base station positioning, but the terminal is required to actively report the information of the network attached base stations to the platform, so that the terminal cannot feel. Moreover, if the terminal does not report, the terminal base station positioning cannot be obtained, and part of the terminal parts of the internet of things have the capability of actively reporting the information of the network-attached base stations, so that the base station positioning of the part of the terminal parts of the internet of things cannot be performed.
The terminal positioning scheme provided by the embodiment of the invention can avoid the technical problems existing in the base station positioning schemes of the two mobile communication terminals, and is described in detail below.
Referring to fig. 1, fig. 1 is a flowchart of a terminal positioning method according to a first embodiment of the present invention, including the following steps:
step 11: acquiring a target base station identifier accessed by each terminal according to the internet log data of at least one terminal;
step 12: determining target geographic position information corresponding to each target base station identifier according to the corresponding relation between the base station identifier and the geographic position information of the base station;
The geographic position information of the base station can be longitude and latitude information.
Step 13: and determining the geographic position of each terminal according to the target geographic position information.
The terminal positioning method provided by the embodiment of the invention can be applied to a big data processing platform. The correspondence between the base station identification and the geographical location information of the base station may be pre-stored (pre-deposited) in a database associated with the big data processing platform.
It should be noted that, the event that the mobile communication terminal accesses the mobile communication network may be simply referred to as an attach network, and correspondingly, the base station that the terminal accesses may also be referred to as an attach network base station of the terminal. A mobile communication terminal that communicates using a cellular network, i.e., a terminal that communicates using mobile 2G, 3G, 4G communication modules and cards.
According to the embodiment of the invention, the network log data of the cellular network is mined in real time, and the base station positioning of the terminal can be efficiently obtained under the condition that the terminal does not sense or does not need terminal support by combining the corresponding relation between the base station identification and the geographic position information of the base station. In addition, when the internet log data of a cellular network is mined, large data mining can be performed on the internet log data of all terminals accessing a certain cellular network, namely a target cellular network, so as to obtain target base station identifiers accessed by all/batch of terminals, and then corresponding target geographic position information is determined by using the corresponding relation between the pre-stored base station identifiers and the geographic position information of the base stations, so that base station positioning data (or called base station positioning information) of a large number of terminals can be obtained simultaneously and efficiently.
Where a cellular network may refer to all cellular networks of one operator.
The above-described terminal positioning method is exemplified below.
Alternatively, the internet log data of the at least one terminal may be obtained by a gateway general packet radio service support node (Gateway GPRS Support Node, GGSN)/packet data network gateway (Packet Data Network Gateway, PGW), for example, the total terminal internet log data in the target cellular network may be obtained.
Specifically, after the terminal attaches to the network, the Serving general packet radio service support node (Serving GPRS Support Node, SGSN)/MME/Serving Gateway (SGW) reports the terminal information to the GGSN/PGW. Further, after the mobile communication terminal starts the traffic service function, the SGSN/MME/SGW in each area will send the log data of the terminal to the GGSN/PGW, which is the existing procedure of the cellular network. And then the GGSN/PGW gathers the Internet log data of the target cellular network full-quantity terminal and sends the summarized Internet log data to the big data processing platform.
Of course, the log data may be obtained in other manners, for example, as the mobile communication technology evolves, the network element collecting the log data may change, and the network element involved in the transmission process of the log data may also change correspondingly, which is not limited herein.

The following illustrates a specific flow of the above terminal positioning method:
and step 1, the big data processing platform acquires Internet log data of the target cellular network full-quantity terminal from GGSN/PGW. Regarding the flow of session establishment and charging signaling in cellular communications, reference is made to the related art, and will not be described in detail herein.
And step 2, the big data processing platform processes the internet log data of the full-quantity terminals in the target cellular network in real time in a streaming mode so as to finish data conversion and cleaning.
And step 3, the big data processing platform extracts the internet log data of 10000 terminals from the internet log data of the full quantity of terminals which finish data conversion and cleaning.
And step 4, the big data processing platform acquires the base station identifier and the corresponding access time of each terminal in 10000 terminals according to the internet log data of the 10000 terminals. For example, for terminal a, according to the Accounting-Request (start) message containing base station identifier a at 15 hours 10 minutes 36 seconds on a certain day, terminal a is acquired to access to base station a at 15 hours 10 minutes 36 seconds on the same day, according to the Accounting-Request (update) message containing base station identifier B at 15 hours 30 minutes 45 seconds on the same day, terminal a is acquired to switch to base station B at 15 hours 30 minutes 45 seconds on the same day, according to the Accounting-Request (update) message containing base station identifier C at 16 hours 52 minutes 05 seconds on the same day, terminal a is acquired to switch to base station C at 16 hours 52 minutes 05 seconds on the same day, according to the Disconnect-Request message at 17 hours 38 minutes 41 seconds on the same day, terminal a is acquired to start to not access the network at 17 hours 38 minutes 41 seconds on the same day, according to the Accounting-Request (start) message containing base station identifier D at 17 hours 41 minutes 50 seconds on the same day, terminal a is acquired to access to base station D at 17 hours 41 minutes 50 seconds on the same day; for terminal b, according to the Accounting-Request (start) message containing the base station identifier E at 8.00 minutes and 00 seconds of a certain day, terminal b is acquired to access to the base station E at 8.00 minutes and 00 seconds of the certain day, according to the Accounting-Request (update) message containing the base station identifier F at 8.45 minutes and 56 seconds of the same day, terminal b is acquired to access to the base station F at 8.45 minutes and 56 seconds of the same day, according to the Accounting-Request (update) message containing the base station identifier G at 18.2 minutes and 50 seconds of the same day, terminal b is acquired to access to the base station G at 18.2 minutes and 50 seconds of the same day, and according to the Accounting-Request message at 22.00 minutes and 00 seconds of the same day, terminal b is acquired to not access to the network at 22.00 minutes and 00 seconds of the same day.
And step 5, the big data processing platform obtains the geographic position information of the base station accessed by each terminal in the 10000 terminals in the corresponding access time by inquiring a corresponding relation database of the base station identification and the geographic position information of the base station, and determines the geographic position of the terminal in the corresponding access time according to the geographic position information of the base station. For example, it may be determined that the terminal a is within the coverage of the base station a at 15 hours, 10 minutes, 36 seconds, to 15 hours, 30 minutes, 44 seconds, and 15 hours, 30 minutes, 45 seconds, to 16 hours, 52 minutes, 04 seconds, and 16 hours, 52 minutes, 05 seconds to 17 hours, 38 minutes, 40 seconds, and 17 minutes, 40 seconds, on a certain day, within the coverage of the base station B, and 17 hours, 41 minutes, 50 seconds, and beginning to be within the coverage of the base station D; it can be determined that terminal b is within the coverage of base station E from 8.00 minutes, 00 seconds to 8.45 minutes, 55 seconds on a certain day, within the coverage of base station F from 8.45 minutes, 56 seconds to 18.2 minutes, 49 seconds on the same day, and within the coverage of base station G from 18.2 minutes, 50 seconds to 21.59 minutes, 59 seconds on the same day.
In addition, the big data processing platform can also determine the state information of each terminal in 10000 terminals according to the internet log data. For example, it may be determined that the terminal a is in an on-line state from 15 hours 10 minutes 36 seconds to 17 hours 38 minutes 40 seconds on a certain day, and from 17 hours 38 minutes 41 seconds to 17 minutes 41 seconds 49 seconds on the same day is in an off-line state, and from 17 hours 41 minutes 50 seconds on the same day is started to be in an on-line state; it can be determined that terminal b is in an on-line state from 8.00 minutes 00 seconds to 21.59 minutes 59 seconds on a certain day, and starts to be in an off-line state from 22.00 minutes 00 seconds on the same day.
