Abstract
A telecommunication system having a cellular mobile telephone system in which calls from cellular telephones are routed through a mobile service switching center exchange. Users of the system, having control of respective groups of mobile telephone are able via user terminals to access respective databases in a signalling processor and to place in the data base information about call parameters, such as call restrictions, for ones of the telephone of that user controlled group. When a call is made from any mobile telephone, the call signal is decoded at the relevant exchange and a determination is made as to whether the call originates from a mobile telephone which is a member of a controlled group. If so, the related database in the controller is accessed and the call is controlled in accordance with the appropriate call parameter, on the basis of the information in the related database.
