Abstract: The scope of the present invention is an information transfer system and a mobile station (10) connected to it. In a system according to the invention a mobile station (10) is connected to a terminal device (40) e.g. through either a cable or an infrared connection, and the radio parts of the mobile station (10) are switched off. Through the terminal device (40), a local network, ATM-network (70, 81, 80, 82) and a network server (90) the mobile station (10) is connected over a wired network to a mobile communication switching center (100) or to a telephone network exchange (110, 130). When the connection from the mobile station (10) to a mobile communication switching center (100) or to a telephone network exchange (110, 130) is broken, the mobile station (10) establishes a connection to a mobile communication switching center (100) by radio in the normal way through a base station (105) and a base station controller (104).

Abstract: The invention relates to an integrated data transfer system, the extensive basis of which is constituted by a general cellular radio system, preferably the GSM system, and in which a radio local area network, preferably the HIPERLAN network, is used for communication between data terminals (3a, 3b, 3c, 3d, 3e, 3f) in small areas with dense communications. In addition, the Internet network (6) is used for fast data transfer. The connection between networks is controlled and handled by a gateway computer (1) located in each radio local area network. In view of the cellular radio system, the gateway computer operates like a base station controller (BSC). The radio local area network consists of the coverage areas or cells (4b, 4c) of the data terminals, and it can be formed, changed and dissolved freely. The computer terminals (3c) preferably have an Internet address enabling mobility, whereby the gateway computer (1) handles the routing to the nodes of the network and the mobile Internet nodes visiting it.

Abstract: The invention relates to integrated office communication systems employing a local area network (LAN) for intra-office communications. In the arrangement according to the invention, no other internal networks are needed in the office because computers (10) are connected to the local area network and telephones (5, 7) are either mobile or cordless phones for which there are low-power room-specific base stations (4, 6) in the local area network (LAN). Connections to the outside world are made via a gateway computer (1) and public cellular radio network. Inside the office, the coverage areas of the small base stations (4, 6, 8) are nanocells (4a) of one or a few rooms. A home or small office user has a similar small base station (14) which is cotifected to said local area network via a public communication network (15) and a gateway equipment (13).

Abstract: The present invention concerns an equipment and a method for providing in connection with the fixed communications network (1) a small cellular extension (4), wherein the same kind of radio frequency mobile communication devices (9) can be used as in regular cellular networks (2), in other words, the radio interface (16) of the cellular extension (4) is similar to the radio interface (15) of the regular cellular networks (2). The cellular extension (4) comprises database means (11) for registering the subscribers and for transmitting the calls to the subscribers located in the cellular extension (4) based on the connections between the ISDN numbers of the cellular network determined for the cellular extension (4) and stored into the database means (11), and the IMSI codes of the subscribers.

Abstract: A location management method is provided for packet data transmission in a mobile communication system. To reduce the amount of signalling for location management concerning packet transmission compared to location management concerning normal traffic, location data of the mobile stations utilizing a data service is updated in a special data service user database. Packets to these mobile stations are sent via the cells as indicated by location data in that database. The database resides in a data service center which interfaces a data network.

Abstract: A method is provided for using an application (18) in a mobile station (1). The application has a first mode of operation and a second mode of operation. The first mode of operation is passive. In the second mode of operation the application (18) controls a master control unit (MCU) of the mobile station (1). Also provided is a system for making payments, comprising at least one mobile station (1) which has an associated application (18), a component for using the application (18), and a first transceiver (IR, 20, RF) for providing local data transfer. The system also comprises at least one cash register (21) or the like, which has a second transceiver for providing data transfer (IR2). The application (18) has a capability for causing data to be transferred from the first transceiver (IR) to the second transceiver (IR2).

Abstract: A method for adjusting transmission power in a mobile radio system having radio cells each having a base station, an exchange of the system having a database listing base stations subject to interference as a result of the use of a specific channel. To minimize the number of base stations subject to interference, the exchange steplessly selects the lowest possible power level for use in radio traffic between the subscriber station and a respective base station on the basis of the quality of transmission from the respective subscriber station, and commands a base station respective and the respective subscriber station to use the respective selected power level on a specific traffic channel. The exchange changes the number of base stations in the database of base stations subject to interference, depending on the power level selected for the traffic channel. The respective base station and the respective subscriber station start to use the respective power level on a specific traffic channel.

Abstract: A method for selecting a channel and a base station in a mobile radio system, the geographical coverage area of which is divided into radio cells, each radio cell including a main base station indicated by an identifier, and at least one of the radio cells including at least one infill base station. In the method, the main base station signals with subscriber stations on a control channel having a downlink frequency for signalling from a base station to a subscriber station and an uplink frequency for signalling from a subscriber station to a base station. Each infill base station monitors the subscriber stations at the uplink frequency of the control channel of the respective main base station.

Abstract: A channel allocation method in a cellular radio system. The mobile radios have permanently stored in their memories a first group of radio channels scanned in a normal hunt sequence and a second group of radio channels scanned in a comprehensive hunt sequence. When the control channel of a base station is changed, a channel permanently belonging to the first group is allocated as a new control channel to the base station whenever such a channel is available. If a channel belonging to the second group has to be allocated as a control channel, it is transferred temporarily to the first group and the change of group is announced through control channels to the mobile radios. A channel permanently belonging to the first group is re-established as the control channel of a base station as soon as such a channel is available and the freed channel is returned to the second group.

Abstract: The invention relates to a radio channel allocation method for a radio system in which a mobile exchange (MX) dynamically allocates radio channels to the base stations (BS1, BS2, BS3) from a predetermined pool of radio channels on a call-by-call basis. In the method according to the invention, when any of the fixed stations (BS1, BS2, BS3) detects a line failure in the transmission line between the fixed station and the control centre (MX), the fixed station starts to use only specific fallback radio channels assigned to it in advance from said pool of radio channels; and when the control centre (MX) detects a line failure in the transmission line between the control centre and any of the fixed stations (BS1, BS2, BS3), the control centre removes specific fallback radio channels assigned in advance to the particular fixed station from the pool of radio channels available to the neighbouring fixed stations of the particular fixed station.
