ABSTRACT:
A cellular radio system includes cells or cell groups complementing the network capacity locally. These cells or cell groups have not been presented as neighboring cells for the surrounding network. This means that a mobile station of the cellular radio network will not at any stage become aware of these compelementary separate radio coverage islands on the basis of the neighboring cell information received from a base station. The coverage of these separate cells and cell groups may topologically overlap the other cells of the cellular radio network. An access of the mobile station to the cells of a compelementary system is based on its a priori information of at which frequencies such a complementary radio coverage may be found (depending on the location of the mobile station). At least part of the mobile stations have then an automatic or user-operated facility of scanning these frequencies. Moreover, various checking of access rights and various priority systems may be associated with the use of the complementary systems.
