Abstract: A fingerprint recognition system intended primarily, but not exclusively, for mobile phones in which a fingerprint recognition system recognizes the separate fingers and thumbs of a user and determines a function of the phone which has been previously associated with that recognized finger/thumb of the user. The determined function is then carried out by the phone. The automatic dialling of a predefined telephone number may be associated with each finger/thumb of the user, or other functions such as the selected ring tone may be associates with certain fingers/thumbs. A particular finger/thumb may have different functions associated with it depending the mode of operation of the phone.

Abstract: A cellular system comprises base stations and terminals. A certain first base station (105) supports only a certain first modulation method (301) and a certain second base station (104) supports both the first modulation method (301) and a certain second modulation method (302). In order to perform cell reselection there is communicated information to the terminal (101) about which modulation method those base station support, the cells of which are possible new cells for the terminal. A new cell is selected by utilizing the information about which modulation methods the base station support.

Abstract: In a cellular system information is transmitted from a base station (100, 400) to a terminal (101, 500). Between the base station and the terminal there is defined a paging channel (110) in order to transmit requests for establishing downlink connections, and a broadcast control channel (108, 109) in order to transmit general information concerning the base station's cell. General information concerning the base station's cell is transmitted on the paging channel (110) when the paging channel's (110) information transmission capacity is higher than the total amount of information which has to be transmitted regarding the requests to establish downlink connections.

Abstract: For establishing a local communication connection between a terminal (102) of a cellular radio system and an accessory device (103), a radio channel is identified (301, 302) on which there is no perceivable radio traffic in the cellular radio system, and a communication connection is established (303, 501) between the terminal and the accessory device on the identified radio channel. The radio channel is preferably a code channel of a CDMA system.

Abstract: The invention relates to a method (500) and an arrangement for defining transmission power in a mobile station. The invention can preferably be applied in a TDMA (Time Division Multiple Access) cellular system which offers broadband services and in which the number of time slots to be used for data transfer can be changed during the connection (530). One fundamental idea of the invention is that the transmission power of a new time slot is defined in the mobile station on the basis of the transmission power of at least one other time slot used in the connection (560). If the connection has had one time slot for its use when a new time slot is being allocated, for the transmission power of the new time slot, the same value is preferably set as at the previous time slot.

Abstract: A method of coding an audio signal comprises receiving an audio signal x to be coded and transforming the received signal from the time to the frequency domain. A quantised audio signal {tilde over (x)} is generated from the transformed audio signal x together with a set of long-term prediction coefficients A which can be used to predict a current time frame of the received audio signal directly from one or more previous time frames of the quantised audio signal {tilde over (x)}. A predicted audio signal {circumflex over (x)} is generated using the prediction coefficients A. The predicted audio signal {circumflex over (x)} is then transformed from the time to the frequency domain and the resulting frequency domain signal compared with that of the received audio signal x to generate an error signal E(k) for each of a plurality of frequency sub-bands.

Abstract: A method of operating a mobile communication system supporting data transmission between a mobile station (MS) and a network in a number of a different packet data protocols (PDPs) including a point-to-multipoint-multicast (PTM-M) protocol. PDP data is formatted and unformatted by a subnetwork dependent convergence protocol (SNDCP) according to the PDP of data. The PDP is identified to the SNDCP by a protocol identifier transmitted between the network and the mobile station. In order to allow a MS to receive a PTM-M in an IDLE state, a unique protocol identifier is permanently assigned to PTM-M transmissions whilst other identifiers are dynamically assigned to other PDPs by the network.
