In the step, after the map data is updated, the corresponding map area and the update content can be written into the update log and stored.
In the embodiment of the invention, the terminal equipment acquires and determines the map area where the terminal equipment is located according to the satellite navigation data. And the terminal equipment acquires the map version information of the map data corresponding to the second map area which is locally stored and uploads the map version information and the information of the map area to the server when determining that the map area where the terminal equipment is located is changed from the first map area to the second map area. And then receiving a judgment result of whether the map data sent by the server is the map data of the latest version, and sending a map data updating request to the server under the condition that the judgment result is that the map data is not the map data of the latest version. And then receiving differential map updating data which is sent by the server and corresponds to the second map area, and updating the map data which corresponds to the second map area in the terminal equipment by using the differential map updating data. Based on the technical scheme provided by the invention, the terminal equipment determines that the map data corresponding to the second map area needs to be updated after identifying that the map area where the terminal equipment is located is changed from the first map area to the second map area according to the satellite navigation data, so that the map data is updated timely without active downloading by a user, and the user experience is improved.
The map area mentioned in the above step may refer to a city in which the terminal device is located, such as beijing, shanghai, and the like.
The map data mentioned in the above step may include at least one of: road geographical position data, building geographical position data and traffic sign geographical position data.

In some embodiments of the present invention, after acquiring the satellite navigation data, the terminal device may identify whether it is initially powered on or cold started. If the map data are identified to be the initial power-on or cold start, determining that the map data need to be updated; if the terminal device is identified not to be powered on for the first time or started in a cold mode, when the terminal device judges that the map area where the terminal device is located is changed from the first map area to the second map area, the fact that the map data need to be updated is determined.
The initial power-on means that the terminal device is connected to the power supply for the first time, and the cold start means that the terminal device is restarted after the power supply is cut off. The terminal equipment determines that the map data needs to be updated after recognizing that the terminal equipment is in initial power-on or cold start. Specifically, the terminal device obtains map version information of map data corresponding to a map area where the terminal device is located, which is locally stored by the terminal device.

When the terminal device is not powered on for the first time or is started in a cold mode, the terminal device determines that the map data needs to be updated when the map area where the terminal device is located is changed from the first map area to the second map area. For example, when the terminal device determines that the map area in which the terminal device is located is changed from shanghai to beijing, it is determined that the map data corresponding to beijing stored locally needs to be updated.
When the terminal equipment identifies that the terminal equipment is initially powered on or cold started, determining that the map data needs to be updated; when it is recognized that it is not the initial power-on or cold start, it is determined that the map data needs to be updated when the map area in which it is located is changed from the first map area to the second map area. Therefore, the map data used by the user can be guaranteed to be the map data of the latest version, the user does not need to actively download the map data, and the user experience degree is improved.
In some embodiments of the present invention, after the terminal device acquires the satellite navigation data, the terminal device may further identify whether it is in a moving state.

The duration corresponding to the period may be set according to an actual situation, and the present invention is not limited. The traffic data may include at least one of: road congestion status data and intersection red light waiting time length data.

In other embodiments of the present invention, the terminal device may further determine whether it is in a moving state according to the satellite navigation data. Specifically, if it is recognized that the satellite navigation data corresponding to the satellite navigation data is continuously changed within a set time period, it is determined that the satellite navigation data is in a moving state. The set time length can be set according to actual conditions, and the invention is not limited.
The embodiment of the invention periodically uploads the traffic data updating request and the map area information of the map area where the terminal equipment is located to the server under the condition that the terminal equipment is in the moving state. And then receiving real-time traffic data issued by the server according to the traffic data updating request and the information of the map area, and updating the traffic data corresponding to the map area where the terminal device is located by using the real-time traffic data, so that the dynamic updating of the traffic data corresponding to the map area is realized, a user can obtain the real-time traffic data of the map area where the user is located, and the experience degree of the user is further improved.
In some embodiments of the invention, the method further comprises: when the terminal equipment judges that the latest updating time of the stored map data reaches the updating time threshold value from the current moment, the terminal equipment determines that the map data needs to be updated. The update duration threshold may be set according to a fixed update time set by a map provider, for example, set to be one month, or three months, or five months, or six months, and the like.
In the embodiment, when the terminal device judges that the latest update time of the stored map data reaches the update time threshold from the current time, the map data needs to be updated, so that the map data used by the user can be ensured to be the latest version of map data as far as possible, and the user experience is further improved.
