The invention relates to a cellular radio network and a method for performing location updating in a cellular radio system. The cellular radio network of the invention does not employ fixed location areas as prior cellular radio networks, but it employs a location area configuration which is subscriber station specific and dynamically adaptive. In connection with each location updating it is therefore possible to select an optimal location area for the subscriber station at that particular moment, the selected location area being preferably of an arbitrary size and form. It is thus possible to define the location areas subscriber station specifically in such a manner that, on one hand, it is sufficiently large so that the subscriber station does not have to perform location updating frequently but, on the other hand, sufficiently small so that the paging of the subscriber station does not load the cellular radio network too much. The invention also allows the use of completely subscriber station specific location areas. |
