Abstract

A navigating method for a cell phone with a positioning device and the apparatus thereof are described. The longitudinal and latitudinal coordinates of a guiding mobile in a global positioning system (GPS) are sent to a guided mobile via a short message service (SMS). After decoding the short message contents, the longitudinal and latitudinal coordinates are obtained by the guided mobile. And a navigation application is wakened and launched to perform a navigation function by establishing the longitudinal and latitudinal coordinates as a navigation destination.

Claims

1. A navigating method for a cell phone with a positioning device, comprising:

receiving a short message using a communication module, metadata of the short message containing a coordinate field that records longitudinal and latitudinal coordinates;

accessing the coordinate field to obtain the longitudinal and latitudinal coordinates;

wakening and launching a navigation application linked to the communication module through the received short message;

establishing the longitudinal and latitudinal coordinates obtained from the coordinate field as a navigation destination; and

performing a navigation function of the navigation application using the navigation destination.

2. The navigating method of claim 1, wherein the short message is a message generated by receiving a position coordinate signal transmitted from a GPS, converting the position coordinate signal into the longitudinal and latitudinal coordinates, and encoding the longitudinal and latitudinal coordinates into the coordinate field of the short message.

3. The navigating method of claim 2, wherein the short message is generated by a tracked end and received by a tracking end to navigate the tracking end to the tracked end.

4. The navigating method of claim 1, wherein the short message consists of (a) data of a text message, encoded in a state field, and (b) the metadata external to the text message, which includes the coordinate field and:

a header field, filled with a code to indicate a format of the short message;

a name field, filled with a name representing a user who sends the short message;

a phone number field, recording the phone number of the user; and

a checksum field, filled with a checksum code to detect a transmission error of the short message.

5. The navigating method of claim 1, wherein the wakening and launching are triggered by clicking the short message.

6. The navigating method of claim 1, wherein the coordinate field only records the longitudinal and latitudinal coordinates.

7. A navigating method for a cell phone with a positioning device, comprising:

receiving a short message using a communication module, metadata of the short message containing a coordinate field that records longitudinal and latitudinal coordinates;

accessing the coordinate field to obtain the longitudinal and latitudinal coordinates;

wakening and launching a navigation application linked to the communication module through the received short message; and

displaying a location point corresponding to the longitudinal and latitudinal coordinates obtained from the coordinate field on a map of the navigation application.

8. The navigating method of claim 7, wherein the short message is a message generated by receiving a position coordinate signal transmitted from a GPS, converting the position coordinate signal into the longitudinal and latitudinal coordinates, and encoding the longitudinal and latitudinal coordinates into the coordinate field of the short message.

9. The navigating method of claim 8, wherein the short message is generated by a tracked end and received by a tracking end to navigate the tracking end to the tracked end.

10. The navigating method of claim 7, wherein the short message consists of (a) data of a text message, encoded in a state field, and (b) the metadata external to the text message, which includes the coordinate field and:

a header field, filled with a code to indicate a format of the short message;

a name field, filled with a name representing a user who sends the short message;

a phone number field, recording the phone number of the user; and

a checksum field, filled with a checksum code to detect a transmission error of the short message.

11. The navigating method of claim 7, wherein the wakening and launching are triggered by clicking the short message.

12. The navigating method of claim 7, wherein the coordinate field only records the longitudinal and latitudinal coordinates.

13. A navigating apparatus for cell phone system with a positioning device, comprising:

a guiding mobile, which includes;

a GPS receiving module for receiving at least one position coordinate signals, transmitted from a plurality of satellites, of the guiding mobile'"'"'s current position;

a central processing unit (CPU), for converting the position coordinate signals into longitudinal and latitudinal coordinates, and encoding a short message metadata of the short message including a coordinate field that records the longitudinal and latitudinal coordinates; and
