Method of updating the location information stored by the server with the current location of the mobile device

The present invention relates to a mobile device, and more particularly to a mobile device that updates a location information stored by a server through its current location through a network interface.

Precise positioning techniques (that is, the ability to know the location of a device at any time) can be implemented by a Global Navigation Satellite System (GNSS) receiver. For example, the NAVSTAR Global Positioning System (GPS) developed by the US Department of Defense provides satellite positioning information to all corners of the world. Thus, the receiver can obtain accurate position based on the received satellite positioning information.

In general, a global satellite navigation system receiver (or global positioning system receiver) includes an antenna for receiving radio signals from global positioning system satellites, and a positioning circuit for transmitting according to global positioning system satellites. The incoming radio signal determines the position of the antenna and produces the corresponding location data. The antenna can be placed in a global positioning system receiver or externally via a line. The mobile device can be combined with global positioning system receivers and other devices to provide location data generated using the global positioning system receiver.

The mobile device can have a built-in map that combines the location information provided by the global positioning system receiver to map the path traveled or to indicate the location of the global positioning system receiver on the map. The user can manually input the location of the mobile device indicated on the map to a website (for example, a Facebook server) or through a Messenger program (for example, MSN, Yahoo Messenger, Google talk, etc.) through a browser. Skype, etc.) Manually input to the instant messaging server so that friends or other authorized users can know the current location of the user through the website or instant messaging program. However, for a number of reasons, users may not be able to update the location information stored on the server at any time. As a result, the location displayed on the website or instant messaging may be incorrect, which may cause friends to go to an incorrect location. It is very inconvenient for the user.

The present invention provides a method of updating the location information stored by a server with the current location of a mobile device. The mobile device has a global positioning system receiver. The GPS receiver is used to generate geographic information. The mobile device can be connected to a network interface. The method includes transmitting, by the network interface, a first instruction based on one of the first geographic information generated by the GPS receiver to modify location information stored by the server, and simultaneously updating the first geographic information The mobile device records the location information stored by the server, and only the location information stored by the server recorded by the mobile device and the location indicated by the second geographic information generated by the global positioning system receiver. When the difference between the two is greater than a predetermined distance, the second instruction based on the second geographic information is transmitted to the server through the network interface.

The present invention further provides a method of adding a network address of a server to a mobile device. The mobile device has a global positioning system receiver. The GPS receiver is used to generate geographic information. The mobile device can be connected to a network interface. The method includes determining, by the network interface, the geographic information of the GPS receiver to a server, determining whether the network address of the server is already stored in the mobile device, and when the server is in the network When the path address has not been stored in the mobile device, prompting whether the network address of the server is to be sent to the mobile device, and adding the server when instructing to increase the network address of the server to the mobile device The network address is to the mobile device.

The present invention further provides a method of updating the location information stored by a server with the current location of a mobile device. The mobile device has a global positioning system receiver or a secondary global positioning application for generating geographic information. The method includes establishing a network address for recording a plurality of servers and a destination list of user names and passwords required to log in to the plurality of servers, according to the global positioning system receiver or the auxiliary global positioning application Geographic information for locating a first current location of the mobile device, transmitting the first current location of the mobile device to the plurality of servers, new to the global positioning system receiver or the secondary global positioning application Geographic information to locate a second current location of the mobile device, and to update the second current location to the plurality of servos when the distance between the second current location and the first current location is greater than a predetermined distance Device.

It is an object of the present invention to provide a GPS management system to a mobile device. The global positioning management system is used to construct and manage a list of destinations of at least one server that discloses the location of the user of the mobile device, wherein the server can be a web server, an instant messaging server, or a communication program (Messenger- Like program) corresponds to the server. The mobile device can update the location information stored by each server through the network interface according to the destination list. Moreover, the present invention provides a simple method for notifying a user when location information stored by one or more servers is incorrect.

Please refer to FIG. 1. FIG. 1 is a schematic diagram showing a General Packet Radio Service (GPRS) network system 10 suitable for use in the application of the present invention. Figure 2 is a diagram illustrating a network system 12 that includes a WIFI, 3G, 3.5G, 802.11 series or other wireless transmission protocol to allow a mobile device to be connected to the Internet. The network system 10, 12 includes at least one mobile device 20, 30. The mobile devices 20, 30 can communicate wirelessly with a base station 40 or a wireless network access point 28. Each mobile device 20, 30 includes a mobile GPS receiver 22, 32 (or an A-GPS application). Each of the mobile global positioning system receivers 22, 32 includes a first antenna 23, 34 for receiving global positioning (GPS) related data from the surrounding satellites, and a second antenna 24, 33 for use with the base station 40 or wireless network bridge 28 communicates. Both the base station 40 and the wireless network bridge 28 are connected to the Internet 50. The Internet 50 includes a server 60 for acting as a website host, an instant messaging server, or a server corresponding to a communication program. The server can modify the stored information on the server based on the geographic information (ie, the current location) generated by the global positioning system receivers 22, 32 of the mobile devices 20, 30 according to instructions issued by the mobile devices 20, 30. The location information of the user so that the website or instant messaging program corresponding to the server can display the current location of the user.

Please refer to FIG. 3, which is an illustration of one embodiment of a mobile device 100 suitable for use in network systems 10, 12. The mobile device 100 includes an outer frame 105, a display screen 110 disposed on the outer frame 105, a console or control button 120 for the user to control the mobile device 100, and a global similar to the global positioning system receiver 22, 32. The positioning system receiver 130, the transceiver 140 for communicating with the base station 40, a memory 150, and a processor 160. The memory 150 is used to store the code 155. The processor 160 executes the code 155 to control the operation of the mobile device 100. The memory 150 further includes a code 155 for execution by the processor 160 to provide the global management location system disclosed herein in the mobile device 100. When the display screen 110 is a touch-sensitive or multi-touch screen, the global positioning management system can receive the user's input through touch, so the personal navigation device 100 does not necessarily need a console (or control button). 120.

Please refer to Figure 4. FIG. 4 is an embodiment illustrating a screen display mode of the global positioning management system 300 applied to the mobile devices 20, 30. Presented on the display screen 110 of the mobile device 20, 30 is a list of names 310, and a list (destination list) 320-350 of the server, its currently stored location, and the last updated time. The destination list 320~350 is used to record the network address of the server and the location information stored by the server. For example, in the manifest item 320, the server 1 currently stores the user (more specifically, the global positioning system receivers 22, 32 in the mobile devices 20, 30 that perform the global positioning management system 300). The network interface sends a first instruction based on the geographic information generated by the global positioning system receivers 22, 32 (the first instruction is used to modify the location information of the user stored on the server) to update the server to store The current location is "a" (that is, the location corresponding to the server 1 or the instant messaging program is "a"). Since the mobile devices 20, 30 are not necessarily connected to all the servers in the lists 320-350 at the same time (for example, the user does not log in to all the instant messaging programs at the same time, or the user does not log in to all the websites at the same time) And the mobile device 20, 30 may only transmit the first command to the server with the connection to update the location stored by the server, so different servers may display different locations.

In the right half of FIG. 4, it is used to assist in the description. In the present invention, the global positioning management system 300 is used to determine that the location stored on the server is correct (ie, the location stored by the server is the immediate location) or not. Correct (meaning that the location where the server is stored is out of date). The method determines whether the distance between the position of the mobile device 20, 30 and the location stored by the server is greater than a predetermined distance (predetermined radius, update distance). As shown in the right half of Fig. 4, it is assumed that the personal navigation device 20, 30 is currently in the "old position", and the solid circle indicates a circle having a radius of a predetermined distance centered on the "old position". At this time, the position "a" (displayed at the position of the server 1), "b" (displayed at the position of the server 2), and "n" (displayed at the position of the server n) are in the solid circle. Therefore, the distance between the location displayed by the servers 1, 2, and n and the current location of the mobile devices 20, 30 is less than the predetermined distance, so the global positioning management system 300 determines that the locations stored by the servers 1, 2, and n are all located. To be correct. At this time, the global positioning management system 300 does not need to update the locations stored on the servers 1, 2, n.

However, it is assumed that the user continues to move so that the mobile devices 20, 30 move to the "new position", and the dotted circle represents a circle centered on the "new position" with a predetermined distance as a radius. As shown in the right half of Fig. 3, the positions "a" and "n" are still maintained in the dotted circle at this time, so that the positions stored in the servos 1, n are correct. However, the location "b" stored by the server 2 is outside the dotted circle, so the global positioning management system 300 determines that the location stored by the server 2 is incorrect and needs to update the location stored by the server 2.

If the global positioning management system 300 can be connected to the server in the destination list, the location stored on the update server is the current location, but regardless of whether it can be connected to the server in the destination list, the global positioning management system 300 The geographic information generated by the global positioning system receivers 22, 32 of the current mobile devices 20, 30 is periodically compared with the location information transmitted to the servers in the list by the first command. Although the global positioning management system 300 can also read the location stored by the server by connecting to the server, the destination list stored directly in the global positioning management system 300 is still directly compared to the location that was last transmitted to the server. The best way. Global positioning whenever the difference between the geographic information generated by the global positioning system receivers 22, 32 of the mobile devices 20, 30 and the location information transmitted to the servers in the list by the first command is greater than a predetermined distance The management system 300 determines that the location stored on the server is incorrect and needs to be updated. The update can be done by uploading the current location, or simply notifying the server that the location it is storing is incorrect (for example, transmitting "information unknown" to the server).

In addition, the user may not want the global positioning management system 300 to update the location stored on the server at any time (for example, the user does not want to display the current location on the MSN at any time), however, usually the user still wants to be in the destination list. The server in the middle will not display the incorrect location. Thus, embodiments derived from the spirit of the present invention may also choose not to determine the distance between the current location of the mobile device 20, 30 and the location that was last updated on the server, but rather to periodically update the destination list. One or more servers in the middle to reflect the user's current location. In other derivative embodiments, the global positioning management system 300 does not have to periodically update the location information of the server, but updates the location stored by the server when it is determined that the location information of the server is incorrect. In addition, the global positioning management system 300 can also directly update the location information of the server in the destination list periodically, and also update the location information of the server when it is determined that the location information of the server is incorrect. Therefore, when the global positioning management system 300 determines that the location stored by the server is incorrect, the present invention provides an embodiment such as shown in the lower left half of FIG. 4, and the mobile devices 20, 30 can provide a message to the user. The message contains a name 360, a specific message (such as the location of server 2 is incorrect), and a list of selectable actions. For example, in the selectable action list, there are options such as "update", "notification location error", "update all", and "cancel", wherein "update all" means that all the destination list is globally located. The management system 300 determines that the location stored by the server storing the incorrect location is updated to the current location, and "cancel" indicates that the location stored by the server is not updated. As such, the global positioning management system 300 can perform the corresponding actions according to the options selected by the user.

In the destination list, the global positioning management system 300 establishes information related to the servers in the maintenance destination list 320-350, wherein the database and method for maintaining information related to the website are known to the industry, in order to enhance understanding. An embodiment 400 is provided in FIG. 5 for a more detailed description. However, the embodiment 400 of FIG. 4 is merely illustrative, and the manner of maintaining the list of the present invention is not limited to the embodiment 400.

As shown in FIG. 5, the destination list is composed of a plurality of tables, each of which contains at least one network address (such as IP or URL) of a server storing the location of the user, and the table may also include a server Other relevant information, such as login information (user name and / or user password), location information type (precise location, such as latitude and longitude, or approximate location, such as city name, or display "office", " Home, etc.), currently stored location, update distance (meaning the predetermined distance used to determine whether the location stored by the server is correct or incorrect), update message (when the location stored by the server is The message displayed when updating, for example, a new location, or "currently unknown", and other design fields. In addition to the server's network address, all fields can have preset values. Users can change the preset values of all forms by adjusting the preferences, or directly change the fields of one of the fields.

There are at least two ways to fill in the fields of the network address. The global positioning management system 300 can include a menu or button to allow the user to add a server in the connection to the destination list, or when the global positioning management system 300 determines one of the first instructions with geographic information (the first When an instruction is used to modify the location information stored by the server), when it is transmitted to a server, it can be checked whether the network address of the server has been stored in the mobile device (the destination list in the mobile device), when When the server's network address is not in the mobile device (the destination list in the mobile device), the global positioning management system 300 can automatically store the server's network address in the mobile device (the destination in the mobile device) Checklist), or display a message asking the user whether to store the server's network address in the mobile device (the destination list in the mobile device), and perform the corresponding action according to the user's response.

Please refer to FIG. 6. FIG. 6 is a flow chart of adding or updating a server's network address or other server related information to a mobile device (a destination list in a mobile device) according to an embodiment of the present invention. The steps are as follows: Step 1000: Determine whether the geographic information of the GPS receiver has been transmitted to a network address through the network interface; Step 1010: (not necessary) prompting the user when determining that the geographic information has been transmitted Enter server related information (such as network address, login data, location information type) to store server related information in the mobile device (destination list in the mobile device); Step 1020: Set according to the user's preference And updating the server related information corresponding to the transmitted network address to the mobile device (the destination list in the mobile device).

Updating the destination list of the mobile device includes two ways. When the network address has not been stored in the destination list, the network address is added to the destination list; when the network address is stored in the destination list The field of the current location in the destination list is updated based on the first instruction transmitted to the network address to modify the location information of the user.

It should be noted that in the present invention, according to the needs of the user, the global positioning management system 300 can establish and maintain all the history records of the instructions transmitted to the network addresses, so when the user wants to view the history. The global positioning management system 300 can provide the historical record to the user. In addition, the global positioning management system 300 is not limited to having only one destination list, that is, according to the needs of the user, the global positioning management system 300 can simultaneously maintain a plurality of items partially overlapping or items without overlapping destination lists, for example, In this case, the list of destinations corresponding to different servers is maintained to allow the user to view related information corresponding to different servers, and the priority order when updating the server can be adjusted. For example, a first destination list contains servers that only family members or friends have permission to read, and a second destination list contains servers that all have permission to read, in which case, use The preference setting may be adjusted so that the update distance corresponding to the server in the first destination list (that is, the predetermined distance used to determine whether the location stored by the server is correct or incorrect) is small, and the display may be displayed. The exact location (such as latitude and longitude) and the higher priority processing order of the server in the second list when updating.

Please refer to FIG. 7. FIG. 7 is a flow chart of updating the location information stored by the server in the destination list of the mobile device according to an embodiment of the present invention. The steps are as follows: Step 1050: Periodically Calculating the difference between the current location of the GPS receiver and the location information stored in the destination list (that is, periodically calculating the current location of the GPS receiver and the server records recorded by the mobile device The difference between the stored location information); Step 1060: When the current location of the GPS receiver and the location information stored in the destination list (that is, the location information stored by each server recorded by the mobile device) When the gap between the two exceeds a predetermined distance, it is determined that the server corresponding to the location information stores incorrect location information; Step 1070: (not necessary) when determining that the server corresponding to the location information is stored incorrectly In the information, the user is notified that the location information of the server is incorrect, so that the user can select to update or cancel the update; Step 1080: According to the user's preference, the server displays the incorrect location information to notify the server that displays the incorrect location information, "notify the location error", or use the geographic information of the GPS receiver. Make an update.

In step 1080, only when the location indicated by the first geographic information (that is, the location stored in the destination list or the location stored by the server recorded by the mobile device) and a second geographic information A second command based on the current position of the GPS receiver (for modifying the server) is transmitted when the difference between the indicated location (the current location of the GPS receiver) is greater than the update distance (predetermined distance) The location information of the user) to each server in the destination list. The second command may instruct the server to update the stored location to the current location or only instruct the server to remove the stored location.

According to the preference setting of the embodiment and the user, when the geographic information is uploaded to a server, the global positioning management system can ask the user whether to add the server to the destination list, or automatically increase the server to the destination list. . In addition, when the global positioning management system determines that the location information stored by the server is incorrect, the global positioning management system may ask the user whether to update the server, automatically update the server, or perform other spirits according to the present invention. Possible action.

Please refer to FIG. 8. FIG. 8 is a schematic diagram showing an application (such as an instant messaging program) corresponding to a server displayed on the display screen of the mobile device (examples 1250, 1260, and 1270). Shown in the example 1250 is the instant messaging program corresponding to the server 1, in the upper right corner, the location of the mobile device (user) stored before the server 1 is displayed, or the mobile device is displayed. The movement causes the server 1 to be in the position of the next update, and may also display the updated location information when the person in the contact list is updated. In addition, the list of friends displayed in the lower half or the list of contacts (common social networking sites or instant messaging programs (such as MSN) have similar functions). The contact's name (nickname) can be displayed next to the contact's location on the server. By adjusting the settings of the application, it is possible to select whether to display the location information, or to display the location information only when the contact and the cursor are selected to move to the contact's name. In addition, the user can set permissions to determine whether other people can see the location information stored by the user on the server. The method for setting permissions is a conventional technique. For example, the method of setting permissions has been widely applied to social networking websites, and therefore will not be described again.

Example 1260 is similar to instance 1250, but in example 1260, the user stores two different location information on different servers. For example, the location stored on the server 2 is (Taoyuan, Taiwan). When the user chooses not to update a particular server and the user's mobile device moves the location, different servers store different location information. Shown in example 1270, there are two contacts setting permissions to the user to allow the user to see their location information. Further, the examples 1250 to 1270 are intended to enhance the understanding of the present invention, and the present invention is not limited thereto.
