    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.

    Abstract: In a cellular radio system having in each of a plurality of cells at least one base station communicating with mobile stations located within its area, the base stations each transmit a pilot signal to the mobile stations. At least one of the base stations, transmits to the mobile stations by transmitting a pilot signal by using a rather narrow changing antenna beam. The angle of the greatest gain of the antenna beam is controlled in such a way that the antenna beam sweeps the cell area. The mobile stations can use the pilot signal in the identification of a base station, and as an indicator of a need for handover, without the continuous reception of the pilot signal in the subscriber equipment, and without a need to transmit the pilot signal with a higher transmission power than the other signals.

    Abstract: A receiver for receiving a signal of a desired user, which signal may arrive at the receiver along several different paths with several different delays, and which receiver has an antenna array consisting of several elements and one or more channel units for demodulating the desired received signal component. Each channel unit searches for the incoming directions and delays of the received signal components, and indicates the parameters of the best components for demodulation. The receiver is connected to the antenna array for analogically phasing the received signal so that the gain from the antenna array is the greatest in the desired beam-like directions.

    Abstract: The base stations of a cellular radio system direct their respective antennas effectively towards the terminal equipment with which they are respectively communicating. Each terminal equipment maintains and updates a list of base stations serving and potentially available to serve the respective terminal equipment. Updating is based on measuring signal strengths and directions, as well as directions of motion of the respective terminal equipment, so that each list, as updated includes only those base stations serving, and on the basis of forecast direction of movement of the terminal equipment, likely to be able to serve the respective terminal equipment. The terminal equipment measure signal strengths for the listed base stations, to determine the need for a handover.

    Abstract: A soft handoff in a cellular telecommunications system in which a user mobile station relays user communication radio signals via at least two base stations to and from a controlling mobile exchange connected to another system user. The relay of user information signals is performed by using digital frames carried on digital transmission connections in the uplink and downlink directions. The differential delay of the two or more terrestial routes between the base stations and the exchange is compensated by a novel time alignment procedure. Each of the base stations sends time alignment request to the mobile exchange which performs the frame time alignment of the downlink transmissions by taking into account TA requests from all base stations.

    Abstract: A system and a method for controlling the radio signal quality between a plurality of mobile stations and a plurality of base stations connected to a mobile switching center of a code division multiple access (CDMA) cellular telecommunication system. Each base station is adapted to measure the quality of each active CDMA communication link and to report for each active CDMA radio communication to the mobile switching center the corresponding measured communication signal quality. The mobile switching center is adapted to perform an averaging process on the reported quality measure values, in order to calculate a recommended quality measure threshold value. The base stations are adapted to receive the recommended threshold value for use in an uplink closed-loop power control algorithm for the mobile stations.
