A method of controlling services on a mobile phone network (geran) to avoid using up radio resources

摘要

A method of controlling services on a mobile phone network comprises causing a network controller to broadcast a message to all users within a cell on a network requesting a response from users having a specific attribute. Each mobile station which responds to the broadcast sends only an initial message of a standard network contention access procedure directly to the network controller; such that the number of responses may be processed by the network controller without any mobile station identifier being provided to the network controller.
