  • Patent number: 11611889
    Abstract: Disclosed is a method for improving system performance in a wireless communication network comprising one or more network cells. Each network cell comprises one or more transmission points transmitting cell specific information. The method comprises determining (201, 401) whether a first TRxP comprised in a first network cell fulfills a utilization criterion. When it is determined that the first TRxP fulfills the utilization criterion (202, 401) the method further comprises gathering (204, 403) utilization statistics associated with the first TRxP and/or with the first network cell, evaluating (205, 404) the gathered utilization statistics and determining (206,405), based on the evaluated utilization statistics, whether moving the first TRxP to a second network cell will improve overall system performance of the wireless communication network. Also disclosed are arrangements, transmission points, radio control functions and computer program products.

  • Patent number: 10652789
    Abstract: There is provided mechanisms for location based mobility measurement activation. A method is performed by a network node. The network node is configured to provide network access in a first cell. The method comprises determining, according to information of at least one measurement area, whether wireless devices are to perform mobility measurements for a possible handover to another network node or not. Each of the at least one measurement area has a dynamically changeable size. The size depends on position dependent events of the wireless devices in the first cell. The method comprises providing mobility measurement activation instructions to the wireless devices in the first cell in response thereto.

  • Patent number: 8014342
    Abstract: By adapting its search procedures, a user equipment in a mobile communication system can shorten the time needed to find a cell or public land mobile network. If a first cell in a first radio access technology has been found, the equipment can exclude one or more frequencies from a search for cells in a second radio access technology. Thus, time and power are not wasted searching for cells in the second radio access technology that cannot be found.

  • Patent number: 7917113
    Abstract: A method for synchronizing measurements in a mobile communication apparatus having a first active radio access means (100) adapted to communicate according to a first radio access technology (RAT) and at least a second passive radio access means (200) adapted to communicate according to a second RAT. A time reference common to the first and the second access means (100) is generated. At least one time schedule is obtained, said schedule indicating at least one time gap wherein the second access means (200) is allowed to be active. The activation time of the schedule is based on the common time reference. An arrangement adapted to generate the common time reference and the time schedule is also disclosed.

  • Patent number: 7773990
    Abstract: By evaluating a cell selection criterion S during scans for available public land mobile networks (PLMNs), a user equipment (UE) can avoid network service interruptions by not selecting PLMNs for which there exist no suitable cells. The cell selection criterion can be evaluated based on cell parameters either read during the PLMN selection procedure or locally stored before the PLMN selection procedure. It is possible to reduce the time required for PLMN scans and UE power consumption.
