Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Fig. 1 is the network environment synoptic diagram according to a preferred embodiment of the present invention.As shown in Figure 1, showed that wherein Navsat 102, the navigator's vehicle, the Duo Tai that dispose navigator's guider 106 dispose from other vehicles of guider 108 and the mobile communications network of being made up of a plurality of mobile base stations 112 110.
Navsat 102 is used to send satellite navigation signals 104.
Navigator's guider 106 is used to receive the origin and the destination information of user's input, calculates guidance path.
Navigator's guider 106 also is used for regularly receiving the satellite navigation signals 104 that Navsat 102 sends, and calculates current position coordinates.
Navigator's guider 106 is in the guidance path and the current location by the current position coordinates indication that demonstration calculates, by mobile communications network 110 guidance path is mail to each from guider 108, and the current position coordinates that will calculate according to the satellite navigation signals 104 of regular reception mails to each from guider 108.
Be used to receive the guidance path that navigator's guider 106 sends from guider 108, on the display device that self disposes, show this guidance path.
Also be used to receive the current position coordinates that navigator's guider 106 regularly sends from guider 108, the control display device shows the current location of navigator's guider 106 in the show navigator path.
In the specific implementation process, owing to often be marked with the information such as title of important building on the guidance path, so the user can advance according to vehicles under following navigator's guider 106 from the current location of the shown guidance path of guider 108 and navigator's guider 106.
This shows, only need information such as guidance path that accessing mobile communication network just can send by navigator's guider 106 and current position to navigate from guider 108, be specifically designed to the hardware device that carries out satellite navigation and need not to dispose, therefore greatly reduce from the cost of guider 108.
It should be noted that except directly receiving the origin and destination information of user's input,, also can import origin and destination information by user from guider 108 as optionally by navigator's guider 106.Yet, need not to dispose the related hardware that is used to calculate guidance path from guider 108, and only need mobile communication hardware by configuration, the origin of input and destination information are sent to navigator's guider 106 get final product, thereby calculate the navigator path by navigator's guider 106.
In the specific implementation process, the mobile communications network 110 of being responsible for transmission guidance path and navigator's guider 106 current position coordinates can make up according to existing any mobile communication standard, such as but not limited to GSM (Global System for Mobile Communications, global system for mobile communications) standard, CDMA (Code-Division Multiple Access, CDMA) standard or the like.
