  • Patent number: 8660560
    Abstract: The invention relates to a system and method for updating a neighbour cell list of a wireless access node. User terminals to be to be transferred from a first wireless access node of a first wireless access network to a second wireless access node of a second wireless access network are detected. From the first wireless access node, one or more of the detected user terminals are requested to report cell information of a plurality of wireless access nodes of at least one of the first wireless access network and the second wireless access network. The cell information is received from the one or more of the detected user terminals and at least one of the first neighbour cell list and the second neighbour cell list is updated using the received cell information.

  • Patent number: 8626175
    Abstract: The invention relates a method and system for assessing coverage of a wireless access network within a desired area via cooperating wireless access networks and terminals capable of measurement and reporting across the different wireless access networks. The cooperation refers to, among other things, the ability of obtaining coverage assessment for one of the wireless access networks using results of the measurements collected at one of the other wireless access networks. In this manner, more accurate and complete coverage assessment may be obtained, relative to the prior art approaches.

  • Publication number: 20130294286
    Abstract: A mechanism to handle conflict situations relating to configuration parameter value changes that can be made by two or more different self-organizing network functions is provided. The mechanism is based on storing and maintaining at least short term history information on configuration parameter value changes (33, 34, 35, 36) and utilizing the history information to determine whether or not to allow a configuration parameter value change.

  • Publication number: 20130053039
    Abstract: The invention relates to a method for deactivation of at least one first cell of a plurality of cells in a telecommunications network. User devices in the at least one first cell are triggered to report measurement information regarding one or more second cells of the plurality of cells to the telecommunications network. The measurement information is received in the telecommunications network (preferably using the still active at least one first cell) and analysed (in the telecommunications network or by an external system), in order to determine whether one or more user devices in the at least one first cell are eligible for being served by a second cell of the one or more second cells when the at least one first cell would be deactivated. When the one or more user devices are determined to be eligible for being served by the second cell of the one or more second cells, the one or more user devices are transferred, i.e.

  • Publication number: 20130053091
    Abstract: The invention relates to a method for activating at least one inactive cell in a wireless telecommunications infrastructure. The telecommunications infrastructure comprises an active cell containing a plurality of terminals. A presence signal is transmitted in the at least one inactive cell. The plurality of terminals in the active cell detect the presence signal(s) of the one or more inactive cells to gather information from the inactive cell. The information is reported to and received at the telecommunications infrastructure. The information received from the plurality of terminals is processed in a processing system of the telecommunications infrastructure to provide a processing result. The inactive cell is activated when the processing result fulfils at least one activation condition such that at least one of the plurality of terminals is within a coverage area of the activated cell.

  • Patent number: 8209038
    Abstract: A system and method for radio network planning comprises a grid generator and a Monte Carlo analysis module. The Monte Carlo analysis module comprises a snapshot generation module which draws, for each snapshot and for each pixel, a statistical realization from a distribution function relating to slow fading, and a snapshot evaluation module which establishes radio network parameters. The Monte Carlo analysis module further comprises a sub-snapshot generation module which generates at least one sub-snapshot for each evaluated snapshot result, and a sub-snapshot evaluation module (14) for evaluating HSDPA performance parameters based on the sub-snapshot. The sub-snapshot evaluation module (14) comprises a scheduler module (16) which is arranged for scheduling a HSDPA user according to a scheduling scheme.

  • Publication number: 20120108245
    Abstract: The invention relates to cooperation between first and second wireless access networks that can be used to obtain energy reduction for or traffic routing within the overall telecommunications infrastructure while still enabling acceptable network coverage and satisfactory performance by the telecommunications infrastructure as a whole. The cooperation refers to the fact that the wireless access networks provide duplicate coverage in a particular area when both wireless access networks are active, and that traffic can be switched between the cooperating networks in order to temporarily adjust (e.g. switch off) resources of one or the wireless access networks. In this manner, energy reduction and/or traffic routing can be obtained under the constraint that sufficient service coverage and capacity remains at an acceptable quality.
