Providing network service of a cellular communication network using grid fields

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 that is generated by the one mobile terminal, wherein said crossing information is received from said one mobile terminal in response to crossing one grid line,
• wherein the one mobile terminal is arranged to generate said crossing information in response to the crossing one grid line, based on said grid information and on position information of the one mobile terminal,
• wherein said network entity is further arranged to split or merge said grid fields based on a usage pattern of said network service.

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 that is generated by the one mobile terminal, wherein said crossing information is received from 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 usage pattern of said network service.
