Abstract: A fuel cell power system and a method of starting a fuel cell power system. The fuel cell power system includes a fuel cell system having one or more voltage outputs, one or more DC/DC converters each having an output and an input, the input being connectable to the voltage outputs of the fuel cell system, a DC voltage link connectable to the output of the one or more DC/DC converters, and a local load connectable to the DC voltage link. In the system, the local load is adapted to draw power from the fuel cell system to decrease the voltage of the fuel cell system.

Abstract: This invention presents a service of barring the forwarded calls. According to the invention, a subscriber may define in his subscriber information that all calls forwarded to him are to be rejected. In response to receiving a request for establishing a call to a subscriber, his subscriber information is checked to find out if he has defined that calls forwarded to him are to be rejected. If the subscriber information shows that the subscriber wishes to reject the forwarded incoming calls, the call establishment signaling is studied to find out if the call has been forwarded. If the call is determined to have been forwarded, the call is rejected. In a preferred embodiment the subscriber may define a set of allowed numbers from which even the forwarded calls are to be accepted.

Abstract: A telecommunications system comprising a first station and a plurality of second stations. The first station is arranged to request a connection with at least one of the plurality of second stations. The connection request has a location criteria which has to be satisfied by at least one second station, wherein at least one register is provided for storing the location information for at least some of said second stations. A selection function is provided for selecting at least one of the second stations onto which a connection establishment is triggered the basis of the location information stored in the register.

Abstract: The present invention relates to a method for transmitting information to a subscriber in a telephone system in connection with call establishment. In order to achieve more efficient transmission of information between the parties participating in the call establishment, a message designated for a predetermined subscriber or a group of subscribers is stored in a memory means, whereby in connection with the call establishment another party to the call establishment is identified, the message designated for the identified party is retrieved from the memory means, and said message is sent to the identified party in connection with the call establishment.

Abstract: A method and a system for communicating data in a telecommunication network (3) in which the available capacity is not uniformly distributed is disclosed. The system comprises a controller (2) for tracking the locations of a mobile station (1) moving in the telecommunication network (3), and for scheduling the data communication to or from the mobile station in accordance with the available capacity of the network.

Abstract: Within a cellular network, an incoming voice mail message is received at a voice mail server (20), adapted into a format suitable for transmission by a network connection which does not meet a delay requirement for delay sensitive information, dispatched to a mobile station (30), and received, readapted and stored thereat within a storing means (35). Adaptation, transmission, reception and readaptation conform to standards such as the GPRS and the UMTS. The voice mail message is dispatched directly to the mobile station (30) via an IP address of an ISDN address thereof. In this manner, instead of dispatching a message via the SMS, the sending of an adapted voice mail message directly to a mobile station (30) and storing it thereat makes it possible to avoid that a user has to poll a service center by calling in order to have the message delivered.

Abstract: In a communications system, the subscriber data in a home network of a subscriber is provided with a subscriber ciphering profile, which indicates whether an unciphered call, session or data packet is to be rejected, accepted or handled in some other manner. A serving network checks the subscriber ciphering profile in one or more of the following cases: 1) for each setup of an unciphered call or connection, 2) for each unciphered packet switched data transmission session, or 3) for each packet data transmission originating from subscriber equipment, and rejects or accepts the unciphered call, connection, session, or data packet, respectively, according to the subscriber ciphering profile. As a result, unciphered calls, sessions, or packet data transmissions will be reliably rejected.

Abstract: System and method for providing a service to a subscriber in a network. A specific network information of a mobile station (1) is provided to a service provider (5) which generates an individual service message on the basis of the provided network information. The provision of the network information may be dependent on a predetermined subscriber condition. Thus, the service message can be transmitted to predetermined subscribers without requiring the subscriber to generate and transmit the specific network information to the service provider (5).

Abstract: The present invention relates to a communication system comprising a sub-scriber A terminal (MSA), a subscriber B terminal (MSB), a message centre (MC) for transmitting a message from subscriber A to subscriber B on the ba-sis of address data included in the message, and a billing database (31) for maintaining subscriber-specific billing data. The system also comprises means for retrieving information from a third party from a database (DB), means for transmitting said information from a third party to subscriber B in connection with a message sent by subscriber A, and means for adding at least part of the charge incurred by transmitting the message and/or at least part of the cost of the contents of the message to the billing database (31) onto the advertiser's account.

Abstract: In a communications system, the subscriber data in a home network (HLR) of a subscriber (UE) is provided with a subscriber ciphering profile which indicates whether an unciphered call, session or data packet is to be rejected, accepted or handled in some other manner. A serving network (MSC/VLR, SGSN,UTRAN) checks the subscriber ciphering profile in one or more of the following cases: 1) for each setup of an unciphered call or connection, 2) for each unciphered packet switched data transmission session, or 3) for each packet data transmission originating from subscriber equipment, and rejects or accepts the unciphered call, connection, session, or data packet, respectively, according to the subscriber ciphering profile. As a result, unciphered calls, sessions, or packet data transmissions will be reliably rejected if the network operator or the user sets the subscriber ciphering profile accordingly.

Abstract: The invention relates to a handover method in a mobile communication system in which error correction of a radio signal can be arranged with different protection levels. The method comprises measuring the signal level and/or quality of base stations in a mobile station, the signal quality and level of the mobile station at the base station is measured, comparing measurements results thus obtained and other variables of the connection with handover criteria, and handover is performed from the source cell to the target cell, when the handover criteria are met. The invention is characterized by determining at least one handover criterion depending on error correction of the radio connection. The invention further relates to a mobile communication system for performing handover.

Abstract: A digital data transmission system includes a transmitting party, a receiving party, a non-transparent circuit-switched data connection between the transmitting and receiving parties, a control element for changing the data transmission capacity of the data connection, and a sliding-window data flow control protocol where the number of transmitted data frames to which the transmitting party has not received an acknowledgement from the receiving party is not allowed to exceed the size of the sliding window. The transmitting and receiving parties are arranged to change the size of the sliding window when one or both of them receive information from the control element on a change in the data transmission capacity of the data connection.
