As shown in fig. 2, the positioning method may include the steps of:
step 201, under the condition of receiving a positioning request, acquiring a preset configuration table, wherein the preset configuration table comprises at least one server address;
in the embodiment of the invention, compared with the terminal in the prior art, the configuration table is arranged in the terminal and is used for recording the addresses of one or more servers, when the addresses of the servers are recorded, the servers can be the same manufacturer or different manufacturers, and it is understood that the address terminal through the server can communicate with the corresponding server.

The positioning request can be triggered by a user operating the terminal or can be triggered by the terminal, and under the condition that the terminal receives the positioning request, the terminal acquires a preset configuration table according to the configuration information address.
Step 202, sending a request for acquiring a source information table to a corresponding server according to a server address in the preset configuration table;
step 203, receiving a source information table sent by the server, wherein the source information table comprises data source information;
the source information table comprises data source information, and positioning data can be acquired from a corresponding data source through the data source information terminal.
The terminal obtains the server address from the configuration table according to the positioning request, then sends a request for obtaining the source information table according to the server address, the server sends the source information table to the terminal according to the request for obtaining the source information table sent by the terminal, and the terminal receives the source information table sent by the server, so that the corresponding data source information is obtained.
And step 204, sending a request for acquiring positioning data for positioning the terminal to a corresponding data source according to the source information table, and receiving the positioning data sent by the data source.
In the embodiment of the invention, after receiving the source information table, the terminal sends a positioning data request to the corresponding satellite according to the data source information in the source information table, the positioning data request is used for acquiring positioning data, and after the data source acquires the positioning data request, the terminal sends the corresponding positioning data.
Optionally, in some embodiments, the source information table includes at least two data source information, then step S204: according to the source information table, sending a positioning data request for terminal positioning to a corresponding data source, and receiving positioning data sent by the data source, wherein the method comprises the following steps:

positioning data is received from each data source in the source information table.
When at least two source information tables exist in the configuration table, the terminal can send positioning data requests to a plurality of corresponding data sources according to the plurality of source information tables, and after each data source receives the positioning data requests, the terminal correspondingly sends respective positioning data to the terminal so as to acquire the positioning data from the plurality of data sources. After the plurality of positioning data are obtained, positioning can be performed according to the plurality of positioning data, so that the plurality of positioning data are fused for positioning, and the positioning accuracy can be enhanced.
The embodiment of the invention obtains a preset configuration table under the condition of receiving a positioning request, wherein the preset configuration table comprises at least one server address; sending a request for acquiring a source information table to a corresponding server according to a server address in the preset configuration table; receiving a source information table sent by the server, wherein the source information table comprises data source information; and sending a positioning data acquisition request for terminal positioning to a corresponding data source according to the source information table, and receiving positioning data sent by the data source. The server address can be the server address under one or more different service names, and the terminal can acquire the source information table from the corresponding server according to the configuration table when positioning, so that the terminal can acquire the source information table from the manufacturer of the terminal or the server of other manufacturers according to the server address, and then can acquire positioning data from the corresponding data source according to the source information table, thereby realizing positioning and avoiding the problem that the terminal cannot acquire the source information table from the server provided by other service providers in the prior art.
Optionally, in some embodiments, based on the foregoing embodiment, referring to fig. 3, before the step of sending, to the corresponding data source, a request for obtaining positioning data for positioning a terminal according to the source information table, the method further includes:
step S205, determining the type of the application corresponding to the positioning request, and determining the priority of the positioning request according to the type;
in order to ensure that the application with the positioning function is provided with priority service when the resources are limited, in the embodiment of the invention, the applications with the positioning function in the terminal are classified, and the classification of the applications can comprise one or more of traffic safety applications, mapping applications and the like, wherein each class of application has different priorities, and in the positioning process, if the resources are limited, the application with the high priority is preferentially provided for use.
At this time, step S204: the step of sending a positioning data request to each data source in the source information table respectively includes:
step S206, selecting the corresponding data source in the source information table to send a positioning data request according to the priority.
Specifically, because the positions of the terminals are different, the signal intensity of each source data to the position is different or the coverage range of each data source is different, when the terminal moves to a certain position in the embodiment of the invention, the terminal selects one or more data sources to send data according to the attribute of each data source in the source information table in the positioning process.
As an embodiment, the source information table includes a data flow network record and/or a data source record, and the step of determining a type of the application corresponding to the location request and determining the priority of the location request according to the type further includes:
determining the type of the application corresponding to the positioning request;
and determining the priority of the positioning request according to one or more of network/data source authentication modes in the data flow network record and/or the data source record, charging or not, a service area, a data flow bit rate and the type of the application.
The source information table also comprises data flow network records and/or data source records of all data sources, wherein the data flow network records and the data source records comprise network/data source authentication modes, charging or not, service areas and data flow bit rates. In this embodiment, the type of the application requesting positioning is determined, and then the priority of the positioning request is determined according to one or more of network/data source authentication mode, charging, service area, data stream bit rate in the data stream network record and/or the data source record, and the type of the application. For example, determining the priority of the application requesting positioning according to the application type and the network/data source authentication mode in the data flow network record.
As another embodiment, the terminal may further send the type of the positioning request to the server or the data source, where the server or the data source prioritizes the application sending the positioning request according to its own resource situation and application type, and when the resource is limited, the request sent by the application with high priority is processed first, that is, the positioning data is sent to the application with basically high priority first. It should be understood that the manner in which the server or data source prioritizes the applications is the same as the terminal.
Further, in some embodiments, the step of sending a request for acquiring positioning data for positioning a terminal to a corresponding data source according to the source information table, and receiving the positioning data sent by the data source includes:
acquiring a current position;
selecting a corresponding data source in the source information table according to the current position;
and sending a positioning data request to the selected data source, and receiving positioning data fed back by the data source for positioning.
In this embodiment, when obtaining multiple source information tables, only one or a part of data source information in the multiple source information tables may be selected to perform positioning, specifically, in the positioning process, the terminal may first obtain its current position, and then select a corresponding data source to send a positioning data request according to a coverage range of the data source in the source information table, so as to avoid sending a request to the data source where the signal cannot cover the current position of the terminal. For example, when the service coverage of the data source/server a is the current province M, and the service coverage of the data source/server B is the next province N or the next province O, the terminal only sends a positioning request to the data source/server a when the terminal is in the province M, and when the user moves to the coverage of the data source/server B or O, the terminal correspondingly sends the positioning request to the data source/server B.
Further, based on the above embodiment, the step of receiving the positioning data fed back by the data source for positioning further includes:
acquiring a preset application requirement;
positioning according to the application requirements and static attributes and/or dynamic attributes in positioning data sent by the data source;
the static attribute comprises at least one of a security level and a coverage area; the dynamic attribute includes at least one of a transport network status and a data accuracy.
In this embodiment, the positioning requirements of different applications are different, for example, part of the applications require fast positioning speed, but the accuracy can be reduced; part of applications require high positioning accuracy. In this embodiment, a user may set corresponding application requirements for each application in advance, so that in a positioning process, a terminal obtains application requirements of an application that sends a positioning request first, and then positions according to the application requirements and static properties and/or dynamic properties in positioning data sent by the data source, where the static properties include at least one of a security level and a coverage area; the dynamic attribute includes at least one of a transport network status and a data accuracy. For example, the service coverage of the data source a and the service coverage of the data source B are the same, the data security protection level of the data source a is higher, and if the application requirement is security requirement, after receiving the positioning data, the terminal selects the positioning data sent by the data source a for positioning.
