Referring to fig. 1, a schematic diagram of a wireless communication system according to an embodiment of the present invention is shown, where the wireless communication system includes a terminal, a satellite, a base station, an AP, and a third-party network server; the terminal is used for starting a local GPS module to send a positioning request to a satellite after receiving a positioning request sent by local application software, or acquiring a Cell ID by a base station, acquiring network identification information such as BSSID of the AP by the AP, sending the acquired network identification information to a third-party network server, and acquiring an auxiliary positioning result stored in a local database; the satellite is used for acquiring a positioning result of the terminal according to the positioning request sent by the terminal and sending the positioning result to the terminal; the base station acquires the Cell ID of the mobile network registered by the terminal at the current moment and sends the Cell ID to the terminal; the AP is used for sending the BSSID of the AP to the terminal; and the third-party network server is used for translating the Cell ID and the BSSID contained in the network identification information sent by the terminal, generating longitude and latitude information and sending the longitude and latitude information as a positioning result to the terminal.
The embodiments of the present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 2, in the embodiment of the present invention, the process of obtaining the positioning result includes:
step 200: and when a positioning request sent by local application software is received, acquiring a local preset positioning strategy.
In the embodiment of the invention, the terminal establishes an auxiliary positioning database locally, when the terminal successfully positions through a GPS or a network for the first time, the time and the positioning result of successful positioning, the Cell ID corresponding to the terminal during positioning and the BSSID of the AP are obtained as auxiliary positioning results, and the obtained auxiliary positioning results are stored in the auxiliary positioning database, wherein the positioning results comprise the longitude and the latitude of the terminal and the positioning precision of the positioning results. For example, the assisted positioning database created by the terminal may store the obtained assisted positioning result in the form of table 1.
TABLE 1
Specifically, when multiple types of application software exist in all application software installed locally in the terminal and run after receiving a user instruction, the location information of the terminal needs to be acquired, and the application software needing to acquire the location information of the terminal generates a location request according to a location policy set by the user. For example, for weather forecast software, when the terminal receives a user instruction to operate the weather forecast software, the weather forecast software sends a positioning request to acquire weather information of a position where the terminal is located at the current moment, and the weather information is presented on an interface of the terminal. The positioning strategy comprises the highest priority of positioning time and the highest priority of positioning precision, all local application software can be set as the same positioning strategy, and different application strategies can be set for different application software according to the characteristics of the application software; in addition, the positioning accuracy may also include other items with highest priority, and the following description takes the positioning policy including highest positioning time priority and highest positioning accuracy priority as an example.
Step 210: and according to the positioning strategy, acquiring a positioning result based on an auxiliary positioning result stored in a local auxiliary positioning database.
In the embodiment of the invention, after the terminal receives the positioning request sent by the application software, the positioning result is obtained according to the local preset positioning strategy and the auxiliary positioning result stored in the local auxiliary positioning database.
Specifically, the terminal starts a data service, starts a local global positioning system GPS module, and obtains a stored auxiliary positioning result from a local auxiliary positioning database; before the auxiliary positioning result is obtained and the GPS positioning result sent by the GPS module is received, if the network positioning result is obtained through the data service, the positioning result is obtained according to the network positioning result and the auxiliary positioning result stored in a local auxiliary positioning database; before the auxiliary positioning result and the network positioning result are obtained, if the GPS positioning result sent by the GPS module is received, the GPS positioning result is determined as the positioning result; and before the GPS positioning result sent by the GPS module is received and the network positioning result is obtained, if the auxiliary positioning result is obtained, the positioning result is obtained based on the auxiliary positioning result.
Compared with the prior art that only a GPS positioning mode or a network positioning mode is adopted without considering the positioning strategy, the technical scheme is adopted, the positioning result is obtained through various ways according to the positioning strategy, and the best matching positioning result can be obtained according to the requirement of a user.
Based on the above positioning strategy, the acquisition of the positioning result can be divided into the following cases:
in the first case: the positioning strategy is the positioning time with the highest priority.
When the positioning strategy is that the positioning time priority is highest, and before a GPS positioning result sent by a GPS module and a network positioning result are received, if an auxiliary positioning result is obtained, the auxiliary positioning result is used as a positioning result; and the positioning result is directly obtained from the terminal locally without depending on a third-party network server, so that the reliability of obtaining the positioning result is improved.
Optionally, the method for the terminal to obtain the auxiliary positioning result includes: starting a local GPS module, and if a positioning result reported by the GPS module is obtained, acquiring network identification information of a local position at the current moment; searching an auxiliary positioning result corresponding to the network identification information from a local auxiliary positioning database; wherein the network identification information includes CellID and BSSID of AP.
By adopting the technical scheme, before the GPS positioning result and the network positioning result are obtained, if the corresponding auxiliary positioning information is searched from the auxiliary positioning database stored locally, the auxiliary positioning information is used as the positioning result, and the GPS positioning result and the network positioning result do not need to be waited, so that the positioning result obtaining time is shortened.
In the second case: the positioning strategy is the highest priority of positioning precision.
When the positioning strategy is that the positioning precision priority is highest, and the auxiliary positioning result is obtained before the GPS positioning result sent by the GPS module and the network positioning result are received, inputting the auxiliary positioning result into the local GPS module, controlling the GPS module to obtain the GPS positioning result according to the auxiliary positioning result, and waiting for the network positioning result; when a GPS positioning result is obtained before a network positioning result is obtained, determining the GPS positioning result as a positioning result; and when the network positioning result is acquired before the GPS positioning result is acquired, acquiring the positioning result according to the network positioning result and the auxiliary positioning result stored in the local auxiliary positioning database.
Optionally, when a network positioning result is obtained before a GPS positioning result is obtained, if a local auxiliary positioning database of the terminal includes a corresponding auxiliary positioning result, comparing the network positioning result with the positioning accuracy of the auxiliary positioning result, and determining a positioning result with higher positioning accuracy as a positioning result, that is, when the positioning accuracy of the network positioning result is higher than the positioning accuracy of the auxiliary positioning result, presenting the network positioning result as the positioning result, and when the positioning accuracy of the network positioning result is lower than the auxiliary positioning result, presenting the auxiliary positioning result as the positioning result; and if the local assistant positioning database does not contain the corresponding assistant positioning result, taking the network positioning result as the positioning result.
In order to avoid the problem that the accuracy of an auxiliary positioning result obtained by the terminal according to the network identification information is low, under the condition that the positioning accuracy requirement is high, the terminal inputs the auxiliary positioning result into the GPS module, so that the GPS module can narrow the positioning range based on the auxiliary positioning result, and quick positioning is realized.
Further, the terminal obtains the positioning result according to the network positioning result and the auxiliary positioning result stored in the local auxiliary positioning database, and the method specifically includes: and if the auxiliary positioning database local to the terminal contains the corresponding auxiliary positioning result, comparing the positioning accuracy of the network positioning result and the auxiliary positioning result, and determining the positioning result with higher positioning accuracy as the positioning result, namely when the positioning accuracy of the network positioning result is higher than that of the auxiliary positioning result, presenting the network positioning result as the positioning result, and when the positioning accuracy of the network positioning result is lower than that of the auxiliary positioning result, presenting the auxiliary positioning result as the positioning result. By adopting the technical scheme, the network positioning result and the auxiliary positioning result are compared, and the positioning result with higher precision is taken as the final positioning result, so that the precision of the obtained positioning result is improved.
Further, when the GPS positioning result is obtained and the auxiliary positioning database contains the corresponding auxiliary positioning result, comparing the positioning accuracy of the auxiliary positioning result with the positioning accuracy of the GPS positioning result, when the positioning accuracy of the GPS positioning result is higher than the positioning accuracy of the auxiliary positioning result, obtaining the network identification information of the local position at the current moment, and storing the network identification information, the GPS positioning result and the positioning time into the auxiliary positioning database; when the network positioning result is obtained and the auxiliary positioning database contains the corresponding auxiliary positioning result, comparing the positioning accuracy of the auxiliary positioning result with the positioning accuracy of the network positioning result, when the positioning accuracy of the network positioning result is higher than the positioning accuracy of the auxiliary positioning result, obtaining the network identification information of the local position at the current moment, and storing the network identification information, the network positioning result and the positioning time into the auxiliary positioning database.
Further, when the auxiliary positioning result cannot be obtained locally, after the GPS positioning result or the network positioning result sent by the GPS module is received, the network identification information of the local position at the current moment is obtained, and the network identification information, the network positioning result or the GPS positioning result, and the positioning time are stored in the auxiliary positioning database. By adopting the technical scheme, the local auxiliary positioning database is continuously updated based on the GPS positioning result and the network positioning result, so that the positioning result can be quickly obtained when the terminal carries out local positioning again.
Further, when the positioning strategy is that the priority of the positioning accuracy is highest and the positioning result acquisition timeout duration is reached, the terminal still does not acquire the GPS positioning result or the network positioning result, acquires the auxiliary positioning result from the local auxiliary positioning database, and determines the auxiliary positioning result as the positioning result.
In the embodiment of the invention, when the positioning strategy is that the priority of positioning time is highest, the terminal can directly obtain an auxiliary positioning result from an auxiliary positioning database stored locally as a final positioning result without starting a local GPS module and a data service; and when the auxiliary positioning database does not contain the auxiliary positioning result corresponding to the terminal, starting the GPS module and the data service, and acquiring the positioning result through the GPS module or the data service. By adopting the technical scheme, when the positioning strategy is that the priority of the positioning time is highest and the local auxiliary positioning database of the terminal stores the corresponding auxiliary positioning result, the auxiliary positioning result is taken as the positioning result, and the GPS module and the data service are not required to be started, so that the energy consumption of the terminal and the data service volume of the terminal are effectively reduced.
Based on the above technical solution, referring to fig. 3, the following describes in detail a process of acquiring a positioning result by a terminal in conjunction with a specific scenario:
step 300: and when the terminal receives a positioning request sent by local application software, starting a data service, starting a local Global Positioning System (GPS) module and searching in a local auxiliary positioning database.
Step 301: and the terminal waits for obtaining the positioning result.
Step 302: when the positioning result obtained by the terminal is the auxiliary positioning result, judging whether a local preset positioning strategy is the highest positioning time priority, if so, executing step 303, otherwise, executing step 304.
Step 303: and the terminal judges whether the positioning result time-out duration is reached, if so, the step 301 is returned, and if not, the step 301 is returned.
Step 304: and the terminal determines the auxiliary positioning result as a positioning result and reports the positioning result.
Step 305: when the positioning result obtained by the terminal is the GPS positioning result, the GPS positioning result is determined as the positioning result to be reported, the network identification information of the local position at the current moment is obtained, and the network identification information and the GPS positioning result are stored in an auxiliary positioning database.
Step 306: and when the positioning result acquired by the terminal is a network positioning result, judging whether a local preset positioning strategy is the highest positioning time priority, if so, executing a step 307, otherwise, executing a step 308.
Step 307: and the terminal determines the network positioning result as a positioning result and reports the positioning result.
Step 308: the terminal determines whether the assisted positioning database contains the assisted positioning result corresponding to the terminal, if yes, step 309 is executed, otherwise, step 310 is executed.
Step 309: and the terminal compares the network positioning result with the positioning accuracy of the auxiliary positioning result and determines the positioning result with higher positioning accuracy as the positioning result.
Step 310: and the terminal determines the network positioning result as a positioning result and reports the positioning result, acquires the network identification information of the local position at the current moment, and stores the network identification information and the network positioning result into an auxiliary positioning database.
