Network service of a cellular communication network covering a geographical area
First Claim
1. 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 one mobile terminal of the plurality of mobile terminals grid information associated with the grid, andkeeping 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 that is generated by the one mobile terminal,wherein said crossing information is received from the one mobile terminal in response to crossing one grid line, based on said grid information and on position information of the one mobile terminal.
