Description

Positioning query system and method

The present invention relates to a positioning technique, and more particularly to a positioning query system and method.

Most mobile devices (such as mobile phones, tablets, etc.) can obtain their location information (such as latitude and longitude, etc.) through Global Positioning System (GPS). If you combine world map information, users can Understand where the device is located. There are also many social or map applications (applications, APPs, etc.) available on the market that allow users to share their current (current or continuous) location information to other users.

However, the aforementioned method of sharing a location through an application may have the following drawbacks. The user must take the initiative to perform the location sharing action, but in fact it is not easy or impossible to operate in situations such as driving or walking. The aforementioned application usually shares the latitude and longitude coordinates in text form, and the user cannot know the location on the map in time. When the device cannot be viewed or the mobile device without the display is used, the user is less able to know the location information. In addition, during the sharing of the location, the mobile device needs to continuously turn on the GPS to obtain the current location information, which is very power-hungry.

In view of this, the present invention provides a location query system that provides a passive and voiced location sharing mechanism to address the deficiencies of the prior art.

The location query system of the present invention comprises a network telephone exchange, a push request server, a push server and a target device. The VoIP switch receives the query location request via voice call. The push request server generates a push request according to the query location request. The push server sends a push notification based on the push request. The target device obtains location information and transmits the location information in response to the push notification. The VoIP switch provides location information through voice calls.

The location query method of the present invention is used to query the location of a target device. This location query method includes the following steps. Receive a query location request via voice call. A push request is generated based on the query location request. Send a push notification to the target device based on the push request. The location information of the target device is obtained in response to the push notification. Provide this location information via voice call.

Based on the above, combined with the network telephone exchange and the push broadcast technology, the user can passively call the target device to obtain the location information through the voice call mode, and directly listen to the location information of the target device through the voice call. In addition, the user of the target device can share the location information without having to actively open the positioning function.

The above described features and advantages of the invention will be apparent from the following description.

In this embodiment, the target device 700 is loaded with a Positioning Sharing APP (PSA), and the PSA transmits a push tag request combined with the sender ID and the application interface (API) key to push the broadcast. The server 500 registers and becomes the recipient of the push message. After the registration with the push server 500 is completed, the PSA transmits its telephone number (referred to as the target telephone number in this embodiment) and the push broadcast token returned by the push server 500 (for example, an event identity (ID). The token, the device identifier, and the like according to the type of the push server 500 are registered with the push request server 320, and the push request server 320 stores the authorization information, the target phone number, and the push tag. In the note database 340, the aforementioned information is associated with the target device 700. The PSA of the target device 700 can also turn on the GPS function to obtain location information.

In order to facilitate the understanding of the operation flow of the embodiment of the present invention, the positioning query method of the location query system 1 in the embodiment of the present invention will be described in detail below. FIG. 2 is a flow chart illustrating a method for positioning a query according to an embodiment of the invention. Referring to FIG. 2, the method in this embodiment is applicable to each device in the location query system 1 of FIG. 1, and hereinafter, the method described in the embodiment of the present invention will be described together. The various processes of the method can be adjusted accordingly according to the implementation situation, and are not limited thereto.

The network telephone exchange 310 receives the inquiry location request through the voice call from the inquiry device 100 (step S210). Specifically, the query device 100 establishes a call connection with the network telephone exchange 310 by means of a telephone dialing manner. If the query device 100 transmits the location query code, the network telephone exchange 310 issues a voice prompt message for the query device 100 to receive the user. The operation transmits a destination telephone number to the network telephone exchange 310.

It should be noted that, in other embodiments, the query device 100 may directly receive the voice prompt message without transmitting the location query code, or may input the target phone number after being connected. In addition, the target phone number may also be replaced with other specific codes, but the target device 700 also needs to register with this code.

The push request server 320 obtains a location query request (including the target telephone number) from the network telephone exchange 310, thereby generating a push request (step S230). Specifically, the push request server 320 obtains the corresponding push symbol from the token database 340 according to the target phone number to learn the related information of the target device 700. Next, the push request server 320 packages the location query request, the push token, the authorization key, and other related instructions or data in accordance with the push server 500 specification (eg, FCM message, GCM message, notification payload ( In the push request of payload, etc., the push request is sent to the push server 500. The push server 500 can remember that the target device 700 is the recipient according to the push symbol in the push request, and generates and transmits a push notification to the target device 700 according to the push request (step S250).

Next, the PSA of the target device 700 responds to the push notification, turning on the GPS function to obtain location information (eg, latitude and longitude coordinates) about the current location (step S270). In this embodiment, after the target device 700 does not receive the push notification or obtains the location information, the location information is disabled (or the GPS function is turned off) to save power consumption. The target device 700 then transmits the location information in conjunction with the target telephone number and the authorization information to the response processing server 350.

The response processing server 350 reads the corresponding authorization information from the token database 340 according to the target telephone number, and compares it with the received authorization information for verification. Since the location information provided by the target device 700 is a latitude and longitude coordinate, which is not easily understood by the user, the response processing server 350 further converts the location information into a voice location that conforms to the most understandable format of the voice call. The information is stored in the location information repository 330. In this embodiment, the voice location information may be an address corresponding to the latitude and longitude coordinates or a relative position to one or more scenic spots (for example, 15 meters southwest of Taipei 101, etc.).

Then, the VoIP switch 310 can access the voice location information, and provide location information by using the voice call mode to the voice call dialed by the query device 100 (step S290), so that the user of the query device 100 can listen in a non-visual manner. Go to the location information about the target device 700.

It should be noted that the location information may be converted into voice location information by using the text-to-speech function of the response processing server 350 or the network telephone exchange 310, or may be performed by other voice conversion servers, in the embodiment of the present invention. No restrictions.

Based on the spirit of the foregoing invention, a context-assisted description will be further described below. Please refer back to Figure 1. After the user who wants to query the location is dialed to the network telephone exchange 310 through the inquiry device 100 and input the location query code, the target telephone number to be queried can be input according to the voice prompt message (step S1). After confirming that the input information is correct, the VoIP switch 310 transmits a location query request to the push request server 320 (step S2). The push request server 320 obtains the related information (ie, the authorization key, the event ID, etc.) of the target phone number corresponding to the target device 700 from the token database 340 (step S3), and forms a FCM together with the location query request. The message is transmitted to the designated target device 700 via the push notification via the push server 500 (step S4) (step S5). When the PSA of the target device 700 receives the FCM message including the location query request, the GPS function is turned on to obtain the current location information (step S6), and the location information is transmitted to the response processing server 350. In addition, after the PSA of the target device 700 is positioned, the GPS function can be turned off to save power consumption. After receiving the location information from the target device 700, the response processing server 350 verifies and converts the authorization information (step S8) from the token database 340 into a format that is easy for the user to understand (step S9), and then stores it to The information database 330 is located (step S10) and a notification is sent to the network telephone exchange 310 (step S11). The network telephone exchange 310 can load the voice location information from the location information database 330 (step S12), and provide the voice location information (for example, the address issued by the voice) to the querying device 100 through the voice call mode (step S13). ).

In summary, the target device in the embodiment of the present invention temporarily turns on the GPS function only when receiving the push notification with the location query request, thereby saving power consumption during the location sharing. On the other hand, the embodiment of the present invention provides a novel location information providing manner (ie, a voice call), so that the inquirer can conveniently and easily understand the location information of the target device.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention, and any one of ordinary skill in the art can make some changes and refinements without departing from the spirit and scope of the present invention. The scope of the invention is defined by the scope of the appended claims.
