In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides an ultra-large user quantity accurate positioning method, exemplarily, fig. 1 shows an overall flow chart of the ultra-large user quantity accurate positioning method according to the embodiment of the invention, as shown in fig. 1, the method comprises the following steps:
step 100: and producing grid positioning service data at a service end of the mobile network.
As will be appreciated by those skilled in the art, a mobile network typically comprises a public mobile communications network of different systems. For example, a common public mobile communication network structure generally includes an MSC (mobile switching center), a BSC (mobile base station controller base station control), and an MS (mobile station mobility), where the MSC corresponds to a mobile switch entity, the BSC corresponds to a mobile base station entity, and the MS corresponds to a mobile terminal. The BSC controls the wireless signal interaction of the mobile base station with the mobile terminals in the covered sector. One or several mobile base stations form a communication link between the mobile exchange and the mobile terminal, according to the topology of the transport network. In the embodiment of the invention, a mobile switch or other mobile network entities with similar functions are positioned at or used as a service end, and a mobile base station entity which directly performs wireless signal interaction with a mobile terminal is positioned at or used as a broadcasting end. In general, a mobile terminal forms stable signal interaction in a certain coverage sector of a mobile base station.
The service terminal produces grid point positioning service data according to the intermediate data provided by the mobile switch, the mobile switch forms the intermediate data according to the obtained initial data, the initial data comprises basic data in the mobile network and basic data for determining service, and the intermediate data comprises analysis result data inside and outside the mobile network formed by the mobile switch independently. The mesh point location service data includes differential data of mesh points matching the coverage area of the mobile base station attached to the mobile switch.
Step 200: and a broadcasting transmitting terminal for user authentication determination through a mobile network and broadcasting the grid point positioning service data to the user.
As will be understood by those skilled in the art, the user authentication of the mobile terminal is implemented by using a SIM card (Subscriber Identity Module) of the mobile network, and the Identity of the mobile terminal user is confirmed by binding the mobile terminal with the SIM card, and the subscribed service items are provided to the user according to the user Identity. The positioning service data of the embodiment of the present invention includes differential data of an RTK (Real-time kinematic) accurate positioning service, and the accurate positioning service may be bound to a user identity.
Those skilled in the art will understand that the authentication location for user authentication through the broadcasting end of the mobile network may be a mobile base station performing wireless signal interaction with the mobile terminal, or may be a mobile switch establishing a communication link with the mobile base station or a service authentication participant of the mobile switch. The broadcasting end for broadcasting through the broadcasting end of the mobile network comprises at least one broadcasting end, the grid point positioning service data of a plurality of broadcasting ends can be the same or different, and the sector of the mobile base station of the broadcasting end covers the determined user who has wireless signal interaction and subscribes to the precise positioning service.
The method for accurately positioning the ultra-large number of users realizes the authentication process of the ultra-large number of accurately positioned users by utilizing the authentication way of the mobile network, so that the number of the accurately positioned users can be greatly increased.
The mobile base station of the mobile network is used as a data broadcasting broadcast node, so that the users who determine the accurate positioning within the coverage range determined by the mobile base station can obtain the matched grid point differential data at the same time, the real-time (or cached) differential data broadcast efficiency of the determined grid points forms weak correlation with the transmission bandwidth and the number of users, and the real-time problem of orderly and concurrently transmitting the differential data to the ultra-large number of users is solved.
The range coverage of the mobile base station of the mobile network is utilized to determine the determined area of the accurate positioning user and avoid providing the accurate position coordinate of the accurate positioning user to the outside of the mobile network system, thereby effectively ensuring the key privacy of the accurate positioning user in the process of continuously receiving the service.
As shown in fig. 1, in an embodiment of the present invention, the step 100 of producing mesh point location service data at a service end of a mobile network includes:
step 110: and a mobile switch of the mobile network receives the grid information, forms coverage mapping data between the grid point service coverage range and the mobile base station service coverage range by combining the mobile base station information, determines the grid point governed by the mobile switch according to the coverage mapping data, and forms a governed grid point list.
Those skilled in the art will appreciate that the mesh information received by the mobile switch, including mesh point coordinate information and service coverage distance information, may be provided by the reference site network or directly by the mesh point solution server. The mobile base station information comprises base station coordinates and a coverage range, the coverage is influenced by wireless signal fluctuation but can form a relatively stable and predictable coverage range, when the coverage between the mobile base stations is overlapped, the coverage priority in the overlapping range can be judged according to a mobile communication technology system, and the whole coverage range of the mobile base station governed by the mobile switch is basically stable. And forming coverage mapping data of each grid point and each mobile base station in two service coverage ranges according to the coordinates of the grid points and the mobile base stations, and determining the coverage corresponding relation between the grid points and the mobile base stations. And forming the necessary grid points within the whole coverage range of the mobile base station governed by the mobile switch according to the coverage mapping data to form the governed grid points of the mobile switch.
Step 120: and the server registers the managed grid point list of the mobile switch to the resolving server.
Registering with the resolution server includes binding identification information of the mobile switch with a list of governed mesh points. Registration may be periodic, triggered.
Step 130: the mobile switch updates the coverage map data according to the change of the mobile base station.
Changes in the mobile base station include, but are not limited to, changes relating to coverage accuracy such as station increase, station decrease, mobile base station single sector coverage adjustment, and station address change. The change of the mobile base station can cause the change of the whole coverage area, and the larger change of the whole coverage area can change the managed grid point of the mobile switch. Changes to the governed mesh point imply updates to the governed mesh point list registered with the resolution server.
Step 140: and the server side continuously receives the differential data which is formed by the resolving server and corresponds to the grid points in the managed grid point list to form a positioning service data list.
The positioning service data list comprises real-time differential data of the grid points in the managed grid point list or effective cached differential data.
In an embodiment of the present invention, the server may act as a participant or a service of a service in the mobile network.
The method for accurately positioning the ultra-large user quantity in the embodiment of the invention combines the whole coverage area of the mobile network with the distributed grid points to form the membership of the coverage base station and the grid points, establishes the coverage area mapping rule between the differential positioning system and the mobile communication system, and realizes the effective conversion of the differential positioning accuracy and the determined communication coverage area. Providing a geographical feature basis for the orderly spread of differential positioning data over mobile terminals of a mobile communication system. The bidirectional data transmission of the accurate positioning user evolves to a unidirectional broadcasting mode based on geographic features, and privacy disclosure is effectively avoided.
As shown in fig. 1, in step 200, the determining the broadcasting end by the user authentication through the mobile network in the embodiment of the present invention includes:
step 210: and confirming the identity information of the user through the SIM card bound with the mobile terminal.
The uniqueness of the SIM card corresponds to the user identity, and is kept in a value added service system of a mobile network as authentication data for opening corresponding services.
Step 220: the mobile terminal establishes a communication link with the mobile exchange through a network route formed by mobile base stations of the mobile network.
The communication link includes a signaling link utilizing underlying communication between hardware devices and/or a data link formed utilizing payload bandwidth. For example, in the embodiment of the present invention, the mobile terminal and the mobile switch may transmit the identification information through a 3GPP protocol link, but the present invention is not limited thereto. The topology of the mobile network is affected by the transmission network and the link aggregation of the mobile base stations, and different network routes can be formed by using transmission links between the mobile base stations.
Step 230: and the mobile switch determines a broadcasting end where the accurate positioning service user is located according to the user identity information transmitted by the communication link and the communication link.
And when the user identity information is consistent with the authentication data for opening the corresponding service, judging that the mobile terminal opens the accurate positioning service, wherein the SIM card user is an accurate positioning user. The mobile switch can determine the terminal base station of the communication link, and the server side further determines the broadcasting side where the accurate positioning user is located.
The method for accurately positioning the ultra-large user quantity effectively utilizes the authentication process of the mobile network SIM card to realize the authentication process of the accurate positioning service and utilizes the type of the terminal node of the communication link to determine the broadcasting end where the accurate positioning user is positioned, thereby fully reducing the system overhead of service authentication and data planning. The method and the device have the advantages that the positioning service data are pushed in a targeted mode depending on the mobile network, and meanwhile repeated data processing cost in the process of accurately positioning local aggregation of users is reduced.
As shown in fig. 1, in an embodiment of the present invention, in step 200, broadcasting the grid positioning service data to the user through the broadcasting terminal includes:
step 240: the mobile switch determines the corresponding grid point according to the broadcasting end.
As described above, the coverage mapping data formed by the mobile switch may be used to retrieve the mobile base station corresponding to the determined mesh point, i.e., the mesh point corresponding to the mobile base station of the broadcast originating terminal.
Step 250: and the mobile switch determines the grid point positioning service data of the corresponding grid point according to the positioning service data list.
The positioning service data of the corresponding grid point, namely the differential data of the grid point, can be obtained from the positioning service data list of the server by taking the grid point corresponding to the broadcasting starting end as a retrieval condition.
Step 260: the mobile exchanger broadcasts the grid point positioning service data of the corresponding grid point to the accurate positioning service user through the broadcasting transmitting terminal.
And the determined broadcasting end only broadcasts the differential data of the corresponding grid point, a communication link established by the mobile switch and the mobile base station of the broadcasting end transmits the differential data of the corresponding grid point, and the accurately positioned users in the coverage range of the broadcasting end synchronously receive the differential data.
The method for accurately positioning the ultra-large user quantity forms a broadcasting sending end according to the mobile base station where the accurate positioning user is located, forms a flexible positioning service data broadcasting node by utilizing the existing communication link between the mobile switch and the mobile base station, performs targeted positioning service data broadcasting, and forms a dynamic distribution and broadcasting process based on the position of the mobile base station. The potential influence on the mobile network caused by providing accurate positioning service aiming at the continuously increased ultra-large user quantity is effectively avoided.
As shown in fig. 1, in step 200, the determining the broadcast sending end by the user authentication through the mobile network further includes:
step 270: and when the mobile terminal is switched among the mobile base stations, determining a broadcasting end where the accurate positioning service user is located according to the reestablished communication link.
When the mobile base stations are switched rapidly, the authentication process can be omitted, and the broadcasting sending end can be directly judged. And differential signal guarantee is provided for maintaining continuous accurate positioning service process.
An embodiment of a mobile base station and grid point distribution on which the method for accurately positioning a very large number of users according to the embodiment of the present invention depends is shown in fig. 2. In fig. 2, the grid points are laid out in an equally spaced matrix, with the grid point spacing set to 4 '× 4'. The coverage range of the mobile base station is smaller than that of the grid point, the mobile base station is divided into a macro cell base station and a micro cell base station, the coverage radius of the macro cell is possibly close to the service radius of the grid point, and the mobile network planning is not influenced by the grid point. And binding a plurality of mobile base stations to one grid point to form coverage mapping data. One coverage sector of one mobile base station can be simultaneously accessed to hundreds to thousands of mobile terminals, the identification information of the mobile terminals is obtained through a 3GPP protocol communication link, and the information is broadcasted to the mobile terminals through the communication link, so that the number of the accurately positioned users can reach the magnitude of millions to billions.
Fig. 3 shows a working process formed by the working principle of the method for accurately positioning a very large user amount according to an embodiment of the present invention. In fig. 3, the working process includes:
1-a mobile switch establishes a corresponding relation (coverage mapping data) between a grid point and the mobile base station according to base station information and grid information, and determines a corresponding managed grid point (managed grid point list) in a coverage range controlled by the mobile switch from the corresponding relation, 2-a server registers the managed grid point to a resolving server, and 3-the resolving server feeds back differential data (grid point positioning service data) of the managed grid point to the server according to the registration to form a positioning service data list;
