Background
A global positioning system (GNSS) is equipped on an existing mobile terminal device, generally one or more of beidou, Galileo and GLONASS, and the positioning speed of the positioning system depends on the signal strength (such as weak indoor signals and strong outdoor signals) received by an antenna of the mobile terminal device, whether the time of a receiver is accurate and whether ephemeris information of the current position is contained; when the signal is strong, the time is synchronous with the satellite time and the duration of the current position is contained, the positioning can be completed quickly, otherwise, the positioning takes longer time.
In the existing positioning scheme, the mobile terminal device needs to complete a satellite search operation according to the current initial position of the mobile phone, the time of the local device and stored ephemeris data, and after at least 4 satellites are searched, the current position of the user is calculated according to a positioning principle.
The existing mobile terminal equipment periodically updates the time and ephemeris data of the mobile terminal, when a user initiates positioning, the time of the mobile terminal has larger deviation with the satellite time, and the ephemeris data is not the latest data of the current position, so that the positioning time is longer, and the user experience is influenced. Further, when the time deviation is large, the mobile equipment consumes less time when searching for satellites according to the time, and even cannot complete satellite search for a long time; when the ephemeris data does not correspond to the current actual position, the satellite search may not be completed, and the satellite search may be completed only by updating the complete ephemeris data, which takes a long time.

Detailed Description
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, 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.
As shown in fig. 1, an embodiment of the present invention provides a method for updating location data, including:
In this step, the first location information of the mobile terminal at the current time and the second location information of the mobile terminal at the previous time are not acquired through a positioning system, and the rough location information of the mobile terminal can be intelligently sensed through a mobile network or a wireless network.
And step 102, determining the geographical position variation of the mobile terminal according to the first position information and the second position information.
And 103, if the geographical position variation is larger than a preset value, updating ephemeris data required by positioning and/or system time of the mobile terminal.
In this step, in order to avoid the waste of resources and power consumption of the mobile terminal caused by the real-time update of the positioning data by the mobile terminal, the mobile terminal or the base station may be configured with a preset value in advance, and when the position change of the mobile terminal is large (that is, the geographical position variation is larger than the preset value), the mobile terminal is triggered to actively update the ephemeris data and/or the system time of the mobile terminal.
For example, if the geographical location variation of the mobile terminal is greater than 50KM, the mobile terminal actively requests the network server to send ephemeris data and/or system time of the mobile terminal, so that the time required by the satellite searching process when the user initiates positioning next time is shortened, and the positioning time is shortened.
In the embodiment of the invention, by detecting the geographical position variation of the mobile terminal, the ephemeris data required by the mobile terminal to actively update the positioning and/or the system time of the mobile terminal can be triggered when the geographical position variation of the mobile terminal is larger than a preset value, so that the problem of long satellite search time or satellite search failure caused by periodically updating the time of the mobile terminal and the ephemeris data is solved, the positioning speed is improved, and the mobile terminal can be ensured to quickly complete the positioning function at any moment.
Preferably, in the above embodiment of the present invention, step 101 includes:
the method comprises the steps of obtaining first position information of a mobile terminal at the current moment and second position information of the mobile terminal at the previous moment through a base station accessed by the mobile terminal.
After the mobile terminal is connected to the mobile network, the information of the currently accessed base station can be acquired, the position of the base station is known, the relative position between the mobile terminal and the base station at the current moment is used as the first position information of the mobile terminal at the current moment, and the relative position between the mobile terminal and the base station at the last moment is used as the second position information of the mobile terminal at the last moment. Furthermore, the terminal compares the first position information with the second position information to obtain the geographical position variation of the mobile terminal.
Alternatively, step 101 comprises:
the method comprises the steps of obtaining first position information of a mobile terminal at the current moment and second position information of the mobile terminal at the previous moment through a wireless network accessed by the mobile terminal.
When the mobile terminal is not inserted with a mobile card (SIM card, Nano SIM card or Micro SIM card), the mobile terminal cannot acquire the base station information; at this time, if the mobile terminal is connected to a wireless network (e.g., wifi network), the wireless network may acquire the location information of the wireless network entity. And taking the relative position between the mobile terminal and the wireless network entity at the current moment as the first position information of the mobile terminal at the current moment, and taking the relative position between the mobile terminal and the wireless network entity at the last moment as the second position information of the mobile terminal at the last moment. Furthermore, the terminal compares the first position information with the second position information to obtain the geographical position variation of the mobile terminal. The wireless network entity may specifically include: wireless routers, wireless network cards, etc., are not enumerated herein.
Accordingly, step 103 includes:
if the geographical position variation is larger than a preset value, acquiring the current geographical position of the mobile terminal according to a base station accessed by the mobile terminal or a wireless network accessed by the mobile terminal;
sending request information to a positioning server, wherein the request information carries the current geographic position of the mobile terminal;
and receiving ephemeris data which is sent by the positioning server and is matched with the current geographic position of the mobile terminal and is required for positioning and/or the system time of the mobile terminal.
Since the ephemeris data is related to the geographical position of the mobile terminal, i.e. mobile terminals at different positions have different ephemeris data; when the geographical position of the mobile terminal changes greatly, the mobile terminal requests the positioning server to send ephemeris data corresponding to the current geographical position according to the current geographical position, so that the time required by the satellite searching process when the user initiates positioning next time is optimized.
Further, in order to maximize the efficiency of updating the data required for its positioning, the system time of the mobile terminal may be updated simultaneously when the ephemeris data required for positioning is updated.
According to the embodiment of the invention, when the geographical position variation of the mobile terminal is larger than the preset value, the ephemeris data and/or the system time of the mobile terminal are/is actively updated, and under the condition that the hardware performance of the antenna of the mobile terminal is not changed, the satellite searching speed is optimized, the positioning speed and the positioning accuracy are improved, so that the better positioning speed is brought, and the user experience is improved.
Bearing the above example, the updating method provided by the above embodiment of the present invention further includes:
if the geographical position variation is smaller than or equal to the preset value and the mobile terminal is located outdoors at the current moment, acquiring the last positioning starting time of the mobile terminal;
and if the time difference between the current time and the last positioning starting time is larger than a threshold value, updating ephemeris data required by positioning and/or the system time of the mobile terminal.
The mobile terminal is provided with a mobile network, a wireless network, photosensitive and geomagnetic sensor equipment and the like, and the mobile terminal can be judged whether to be indoors or outdoors at the current moment by intelligently detecting one or more of photosensitive, geomagnetic data, mobile network signal intensity and wireless network signal intensity.
Preferably, the mobile terminal is located indoors or outdoors at the current time, and may further perform identification according to a determination condition of machine learning in advance based on the current time, the ambient light intensity, the geomagnetic intensity, the mobile base station signal intensity, and the wireless signal intensity.
Further, in the above embodiment of the present invention, if the time difference between the current time and the time of starting the positioning last time is greater than a threshold value, the step of updating ephemeris data required for positioning and/or the system time of the mobile terminal includes:
if the time difference between the current time and the last positioning starting time is larger than a threshold value, sending a positioning request to a positioning server; in order to avoid the waste of resources and power consumption of the mobile terminal caused by the fact that the mobile terminal updates the data required by positioning in real time, the mobile terminal or the base station can be configured with a threshold value in advance, and the mobile terminal is triggered to actively update the data required by positioning when the time difference between the last positioning starting time of the current time interval exceeds the threshold value.
Receiving navigation message data sent by the positioning server, wherein the navigation message data comprises satellite time and ephemeris data of the positioning server;
updating the system time of the mobile terminal required by positioning according to the satellite time of the positioning server; and/or updating positioning data required by positioning according to the ephemeris data.
The positioning server generally adopts a cesium atomic clock or a rubidium atomic clock, so that the accuracy is extremely high; the clock accuracy of the mobile terminal is lower than that of the satellite clock of the positioning server, and when time synchronization is not performed for a long time, the deviation between the mobile terminal and the satellite clock is larger and larger, so that the positioning accuracy and the positioning speed are influenced.
And when the mobile terminal is in an outdoor open state, the mobile terminal can receive satellite signals, and the navigation message data sent by the positioning server contains time information: the time of week (TOW) and the satellite time, when the navigation message data is received and the positioning is completed, the mobile terminal can further update the time obtained by calculating the navigation message data to the system time of the mobile terminal, and the system time of the mobile terminal is completely the same as or has a very small difference with the satellite time, so that the positioning speed of the next time when the user actively initiates the positioning is improved.
However, since the local time of the positioning receiver of the mobile terminal and the satellite time are greatly deviated after a certain period of time, it can be set that the operation is triggered when the time exceeds 1 day or 2 days and the mobile terminal is in an outdoor environment, so as to update the system time of the mobile terminal required for positioning.
Also, in order to maximize the efficiency of updating the data required for its position determination, the ephemeris data may be updated simultaneously when updating the system time of the mobile terminal required for the position determination.
In the embodiment of the invention, when the terminal is located outdoors and the time difference between the current time and the last positioning starting time is greater than a threshold value, ephemeris data required by positioning and/or the system time of the mobile terminal are/is updated, and under the condition that the performance of mobile terminal antenna hardware is not changed, the satellite searching speed is optimized, the positioning speed and accuracy are improved, better positioning speed is brought, and user experience is improved.
It should be noted that, the above-mentioned embodiments of the present invention refer to a location server including: the GPS (Global Positioning System), the beidou Positioning System, the Galileo satellite navigation System or the GLONASS Global satellite navigation System, which are not limited herein.
In summary, the embodiments of the present invention can implement triggering the mobile terminal to actively update ephemeris data and/or system time of the mobile terminal when the geographical location variation of the mobile terminal is greater than a preset value by detecting the geographical location variation of the mobile terminal, and actively update the ephemeris data and/or system time of the mobile terminal when the geographical location variation of the mobile terminal is less than or equal to the preset value and the mobile terminal is located outdoors, so as to solve the problem of long satellite search time or satellite search failure caused by periodically updating the time and the ephemeris data of the mobile terminal, improve the positioning speed, and ensure that the mobile terminal can quickly complete the positioning function at any time.
