A method and equipment for carrying out special functions in a cellular radio system

摘要

A method and equipment implementing the method by which terminals and cells associated with special functions can be flexibly connected to a radio system. The radio system comprises means for defining priority cells and dividing radio subscribers into subscriber classes. A cell associated with a special function is defined to support the subscriber class or classes associated with said special function only, the cell also being defined as a priority cell. The terminal is arranged to update its subscriber class at least when registering into the system and when a possible change concerning the subscriber class is performed. At this point, new special function cells can be added to the system without having to collect the terminals for redefinition.
