  • Patent number: 7027829
    Abstract: The present invention relates to a method in a communication system. The system comprises a controller arranged to control transmission power of stations, a first station and a second station, the controller being arranged to provide the first station with a target for use in control of the transmission power of the second station, monitoring means, and means for preventing use of a target for the transmission parameter that exceeds a limit value. The controller provides the first station with the target and the first station adjusts the transmission power of the second station on basis of the target. A predefined condition is monitored, and upon occurrence of the predefined condition, use of a target for the transmission parameter exceeding a limit value for the target for the transmission parameter is prevented.

  • Patent number: 6985471
    Abstract: The invention relates to a method for transmitting data from a radio network subsystem over a radio link to user equipment in a mobile telephone system, a radio network subsystem, and user equipment. The radio network subsystem transmits a dedicated physical channel to the user equipment. The dedicated physical channel comprises a dedicated physical control channel and a dedicated physical data channel. The dedicated physical channel is formed by frames to be transmitted to the radio link. During transmission, the radio network subsystem spreads each channel with a spreading code, the length of which spreading code, i.e. spreading factor, determines the data transmission rate.

  • Publication number: 20050141541
    Abstract: A real-time media session is established between user equipment and a media communication server via a serving access network. According to the Invention, dummy data (e.g. a dummy message) is sent in order to maintain a dedicated channel during the inactive periods of a real-time media session or to trigger an early setup of a dedicated channel in the access network. In this manner, user equipment logged on to a real-time media (e.g. PoC) session are prevented from going to a radio resource idle state, thus avoiding potential long extra delays during real-time media (e.g. PoC) service usage. The invention further allows the sending and receiving user equipment to set up dedicated channels (DCH) already during the start-to-talk procedure of the transmitting user equipment, which in turn potentially reduces end-to-end delays during the conversation.

  • Patent number: 6836471
    Abstract: A method and system for inter-operator handover in a telecommunications network comprising a greenfield WCDMA operator and a GSM/WCDMA operator. When a mobile terminal of the greenfield operator is moving from the coverage area of the home network to the GSM/WCDMA area, a neighbor list of GSM cells is provided to the mobile terminal for handover to a GSM cell when the home network coverage is not available. When the mobile terminal is returning home from the GSM/WCDMA area, a neighbor list of the home cells is provided to the mobile terminal so that the greenfield mobile station is connected to its home network whenever there is coverage. Preferably, the neighbor lists are provided to the mobile terminal only in the connected mode.

  • Publication number: 20040198234
    Abstract: A method, system, device and computer program product are provided for analyzing a cellular wireless communication network of a first type. For analyzing the cellular wireless communication network of the first type, communication connection condition parameters for one cell are measured, which communication connection condition parameters are derived from signals received by a mobile station from the one cell and from a plurality of other cells. The communication connection condition parameters are transmitted to a network control element in the form of mobile measurement reports. A network analysis functionality associated with the network control element processes the mobile measurement reports and evaluates, on the basis of processing results, a potential of the one cell for a usage in a wireless communication network of a second type, and/or estimated network parameters of the wireless communication network of the second type, like network performance or network dimensioning.

  • Publication number: 20040121777
    Abstract: The present invention relates to a method and apparatus for controlling a connection transfer in a cellular network having at least two systems, such as a GSM system and a WCDMA system. Based on a load determination, a service-based inter-system or inter-frequency handover of the connection to another system or to another carrier of the same system is initiated if the determined is below a threshold and service priorities are indicating it. If it exceeds the threshold, an additional load-based inter-system or inter-frequency handover can be initiated. If the load of the target cell is not known, a load estimation based on a learning process can be used to derive a probability of success of an interfrequency or inter-system handover, which may be used for deciding on the initiation of the inter-system handover. The learning process may be performed by evaluating preceding interfrequency or inter-system handovers to the target cell or preceding interfrequency or inter-system handovers from the target cell.

  • Publication number: 20040047312
    Abstract: A method and system for uplink interference avoidance that includes a network device and mobile device in a communications network. A signal characteristic of a downlink channel currently not used by the mobile device is measured to determine if the signal characteristic has increased or decreased. The signal characteristic increase or decrease is reported to the network device. The signal characteristic may be, for example, signal quality or signal strength. The interference may be, for example, adjacent channel leakage power ratio (ACLR) interference. A handover from the downlink channel currently used by the mobile device is launched thus avoiding interference in an uplink channel not currently used by the mobile device. An inter-frequency handover or an inter-system handover may be launched.

  • Publication number: 20040029532
    Abstract: A method and system for soft handover detection for uplink interference avoidance that includes a network device and mobile device in a communications network. The mobile device uses a downlink carrier. A parameter, such as a signal strength or a signal quality, of the downlink carrier and one of a co-sited downlink carrier or neighboring downlink carrier is measured. A soft handover area is detected by the network device or the mobile device based on comparing the signal strength or the signal quality of the downlink carrier with the signal strength or the signal quality of one of the co-sited downlink carrier or the neighboring downlink carrier. The downlink carrier, the co-sited downlink carrier or the neighboring downlink carrier may be from a core band, (e.g., 2.0 GHz), or extension band, (e.g., 2.5 GHz), of frequencies or combination thereof. The system provides for handovers while uplink carrier interference is avoided.

  • Patent number: RE38539
    Abstract: Provided is a method and system for a radio system including at least one base station and terminal equipment including a receiver and a transmitter. The transmitter is structured and arranged to independently adjust a symbol rate of at least two signals and combine the two signals after adjusting the symbol rate. The transmitter then transmits the combined signal along one physical path. By adjusting the signal rate before combining the two signals, the transmitter optimizes the signal qualities of each of the signals.
