Abstract

A method for providing a network service of a cellular communication network covering a geographical area for a plurality of mobile terminals, the method comprising: defining a grid covering at least a part of the geographical area with grid fields, framed by grid lines and spaced by a grid spacing; providing grid information comprising reference point information and information on said grid spacing, generating crossing information in response to one of the plurality of mobile terminals crossing one grid line, based on said grid information and on position information of the at least one mobile terminal, and keeping grid field information for at least one grid field comprising identification information of the one mobile terminal when inside the one grid field based on said crossing information.

Claims

1. A method for providing a network service of a cellular communication network covering a geographical area for a plurality of mobile terminals, the method comprising:

defining a grid covering at least a part of the geographical area with grid fields, framed by grid lines and spaced by a grid spacing;

providing grid information comprising reference point information and information on said grid spacing,

generating crossing information in response to one of the plurality of mobile terminals crossing one grid line, based on said grid information and on position information of the at least one mobile terminal,

keeping grid field information for at least one grid field comprising identification information of the one mobile terminal when inside the one grid field based on said crossing information, and

splitting or merging said grid fields based on a current usage pattern of said network service.

2. The method of claim 1, further comprising providing as part of said network service a geographical service based on said grid field information.

3. The method of claim 2, wherein providing the geographical service comprises a registering to the geographical service, and wherein said providing of the geographical service is dependent on said registering to the geographical service,

4. The method of claim 2, further comprising sending a message to at least one of the plurality of mobile terminals based on said grid field information.

5. The method of claim 4, further comprising receiving a request for said geographical service, said message being sent to the at least one mobile terminal based on said request.

6. The method of claim 1, further comprising providing as part of said network service a localized information service to at least a part of the plurality of mobile terminals.

7. The method of claim 6, wherein providing the localized information service comprises a registering of one of the plurality of mobile terminals to the localized information service, and wherein the providing of the localized information service is dependent on said registering to the localized information service.

8. The method of claim 7, wherein said registering comprises providing said grid information to said one mobile terminal.

9. The method of claim 1, further comprising changing said grid spacing,

10. The method of claim 1, further comprising generating grid location information indicating a grid field covering a location of one of the plurality of mobile terminals, said generating being based on said grid information and on said position information of the one mobile terminal, wherein said grid field information is kept also based on said grid location information.

11. The method of claim 1, wherein the cellular communication network covers the geographical area with cells, and wherein the grid fields are independent from said cells.

13. The system of claim 12 adapted to perform a method of claim 1.

12. A system for providing a network service of a cellular communication network covering a geographical area for a plurality of mobile terminals, the system comprising a network entity being arranged:

to define a grid covering at least a part of the geographical area with grid fields, framed by grid lines and spaced by a grid spacing;

to provide to at least one of the plurality of mobile terminals grid information comprising reference point information and information on said grid spacing, and

to keep grid field information for at least one grid field comprising identification information of the one mobile terminal when inside the one grid field based on crossing information,

wherein the one mobile terminal is arranged to generate said crossing information in response to crossing one grid line, based on said grid information and on position information of the one mobile terminal,

and wherein said network entity is further arranged to split or merge said grid fields based on a current usage pattern of said network service.

14. A method of operating a network entity providing a network service of a cellular communication network covering a geographical area for a plurality of mobile terminals, the method comprising:

defining a grid covering at least a part of the geographical area with grid fields, framed by grid lines and spaced by a grid spacing;

providing to at least one of the plurality of mobile terminals grid information comprising reference point information and information on said grid spacing,

keeping grid field information for at least one grid field comprising identification information of the one mobile terminal when inside the one grid field based on crossing information, wherein said crossing information is generated by said one mobile terminal in response to crossing one grid line, based on said grid information and on position information of the one mobile terminal, and

splitting or merging said grid fields based on a current usage pattern of said network service.

15. The method of claim 14, further comprising sending a message to at least one of the plurality of mobile terminals based on said grid field information.

16. The method of claim 14, further comprising providing as part of said network service a geographical service based on said grid field information to a further entity, wherein the geographical service comprises a registering of the further entity to the geographical service, and wherein said providing of the geographical service is dependent on said registering to the geographical service.

17. The method of claim 14, further comprising providing as part of said network service a localized information service to at least a part of the plurality of mobile terminals, wherein providing the localized information service comprises a registering of one of the plurality of mobile terminals to the localized information service, and wherein the providing of the localized information service is dependent on said registering to the localized information service.

18. The method of claim 17, wherein said registering comprises providing said grid information to said one mobile terminal.

19. The method of claim 14, further comprising changing said grid spacing.

20. The method of claim 14, wherein the cellular communication network covers the geographical area with cells, and wherein the grid fields are independent from said cells.

21. A network entity of a cellular communication network comprising a processing unit being configured to perform a method of claim 14.

22. A computer program loadable into a processing unit of a network entity of a cellular communication network, the program comprising code that when running on said processing unit performs a method according to claim 14.

23. A mobile terminal for use in a cellular communication network covering a geographical area, the mobile terminal comprising a processing unit being configured to:

receive grid information comprising reference point information and information on grid spacing, wherein a grid covers at least a part of the geographical area with grid fields, framed by grid lines and spaced by said grid spacing;

observe a crossing of a grid line based on said grid information and on position information of the mobile terminal;

generate crossing information in response to said crossing of a grid line; and

send said crossing information to a network entity over the cellular communication network.
