Patent number: 7545774Abstract: The invention relates to a method for controlling the function of a mobile station in a packet switched communication network based on a cellular network, which communication network is arranged to transfer information between a base station and at least one wireless communication device by means of a radio channel, wherein to transfer information, a transmission power on a set level is used on the radio channel. Information divided into successive blocks (10, B0-B11) is transmitted from the base station to the mobile station on the radio channel. In the method, the block also contains information (PR) relating to the power level of the transmission. In the method, a block (10, B0-B11) that is transmitted repeatedly and at fixed intervals is transmitted with a fixed transmission power to establish a reference level.Type: GrantFiled: August 26, 1999Date of Patent: June 9, 2009Assignee: Nokia CorporationInventors: Riku Rimpela, Petri Jarvinen, Jarkko Oksala, Jari Ruohonen
