Abstract

A system includes a point of interest (POI) database and a power engine. The POI database is used for storing a plurality of POIs used for a satellite navigation system (SNS). The power engine is coupled to the POI database for searching a plurality of desired POIs from the POI database and downloading the desired POIs as a plurality of downloaded POIs to a terminal device via a network. The power engine also receives a modified POI from the terminal device via the network and updates the POI database by uploading the modified POI to the POI database.

Claims

1. A system comprising:

a point of interest (POI) database for storing a plurality of POIs used for a satellite navigation system (SNS); and

a power engine coupled to said POI database for searching a plurality of desired POIs from said POI database and downloading said desired POIs to a terminal device via a network as a plurality of downloaded POIs, for receiving a modified POI from said terminal device via said network, and for updating said POI database by uploading said modified POI to said POI database.

2. The system of claim 1, wherein said downloaded POIs comprise a specific formatted document.

3. The system of claim 2, wherein said specific formatted document is capable of being graphically displayed by an SNS embedded terminal device.

4. The system of claim 2, wherein said specific formatted document is capable of being modified by a network terminal device.

5. The system of claim 1, wherein said downloaded POIs are marked on a POI digital map at a plurality of corresponding positions.

6. The system of claim 5, wherein said system further comprising:

a map database for storing a plurality of digital maps; and

a superposition engine coupled to said map database, said power engine and said POI database for combining said desired POIs with at least one of said digital maps stored in said map database and for generating said POI digital map.

7. The system of claim 6, wherein said map database is capable of providing said digital maps to said terminal device, and wherein said terminal device is capable of uploading a modified digital map via said network to update said map database.

8. The system of claim 1, wherein said terminal device comprises a network terminal device capable of communicating with said power engine via said network according to Hypertext Transfer Protocol (HTTP).

9. The system of claim 1, wherein said terminal device comprises an SNS embedded terminal device capable of communicating with said power engine via said network.

10. The system of claim 1, wherein said power engine communicates with said POI database according to Structured Query Language (SQL) protocol.

11. The system of claim 1, wherein said terminal device transfers said modified POI to said power engine according to Hypertext Transfer Protocol (HTTP).

12. A point of interest (POI) information system, comprising:

a system for storing a plurality of POIs, for providing said POIs and for receiving a modified POI via a network and for updating said system according to said modified POI; and

at least one terminal device operable for communicating with said system via said network, for downloading said POIs from said system via said network as a plurality of downloaded POIs, and for uploading said modified POI to said system via said network.

13. The POI information system of claim 12, wherein said system comprises:

a POI database for storing said POIs; and

a power engine coupled to said POI database for searching a plurality of desired POIs from said POI database and downloading said desired POIs to said terminal device via said network as said downloaded POIs, for receiving said modified POI from said terminal device via said network, and for updating said POI database by uploading said modified POI to said POI database.

14. The POI information system of claim 12, wherein said downloaded POIs comprise a specific formatted document.

15. The POI information system of claim 12, wherein said downloaded POIs are marked on a digital map at a plurality of corresponding positions.

16. The POI information system of claim 15, wherein said system further comprises:

a map database for storing a plurality of digital maps; and

a superposition engine coupled to said map database, said power engine and said POI database for combining said desired POIs with at least one of said digital maps stored in said map database and for generating said POI digital map.

17. The POI information system of claim 16, wherein said map database is capable of providing said digital maps to said terminal device, and wherein said terminal device is capable of uploading a modified digital map via said network to update said map database.

18. The POI information system of claim 12, wherein said terminal device comprises a satellite navigation system (SNS) embedded terminal device for accessing said system and for sending a first SNS signal to an SNS and receiving a second SNS signal from said SNS.

19. The POI information system of claim 18, wherein said POI information system is capable of enabling navigation to said desired POIs by sending said first SNS signal and receiving said second SNS signal.

20. A method comprising:

generating a modified point of interest (POI) at a terminal device;

uploading said modified POI via a network to a POI database which stores a plurality of POIs used for a satellite navigation system (SNS);

updating said POI database according to said modified POI; and

downloading said POIs from said POI database to said terminal device via said network.

21. The method of claim 20, further comprising:

combining at least one digital map with said POIs;

generating a POI digital map marked with said POIs at a plurality of corresponding positions; and

downloading said POI digital map via said network.
