Patent number: 8406146Abstract: In a cellular wireless communications network, measurements are received from a plurality of user equipments relating to the reference signal received powers from a plurality of other cells of the cellular wireless communications network For other cells of the cellular wireless communications network having a physical cell identity (such as a scrambling code) that is the same as a physical cell identity of that first cell, it is determined from the received measurements whether a mutual potential interference level with that cell exceeds a threshold If so, an alternative physical cell identity is proposed, that would cause a mutual potential interference level between the cell or the potentially interfering cell and another cell already using that alternative physical cell identity that is lower than the mutual potential interference level between the cell and the potentially interfering cell.Type: GrantFiled: December 21, 2007Date of Patent: March 26, 2013Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: John Quilty, Anna Pucar Rimhagen, Johan Moe

Patent number: 8320260Abstract: A wireless communication network automatically tests itself for sleeping cells. This is done by designing the base stations to regularly act as a terminal, contact its neighboring base stations and as a mobile perform a set of typical traffic cases. From the outcome of the traffic cases the probing base station detects neighboring base stations that cannot carry traffic. The information about sleeping cells is subsequently communicated from the base station to the operation and maintenance system.Type: GrantFiled: September 5, 2007Date of Patent: November 27, 2012Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Erik Lars Westerberg, Kenneth Balck, Anna Pucar Rimhagen

Publication number: 20110029318Abstract: A global licensing method and a licensing server are described in which licenses for public land mobile network (PLMNs) are allowed to cross PLMN boundaries. The licenses are moved from PLMNs of lower priority to PLMNs of higher priority. In one example, the licenses are moved on a periodic basis. In another example, the licenses are moved on an as needed basis. When demands for licenses are greater than the supply, the PLMNs are prioritized and the licenses are moved from the lower priority PLMNs to higher priority PLMNs. A global license server can be utilized to manage the licenses for the global operator.Type: ApplicationFiled: June 16, 2008Publication date: February 3, 2011Inventors: Anna Pucar Rimhagen, Stefan Engström

Publication number: 20090049152Abstract: Nodes such as base stations in a mobile communication network are divided and grouped into management clusters. One of the nodes in each management cluster is selected to be a master node. The master node aggregates performance data for each of the nodes in its assigned cluster, and sends a consolidated performance management report containing the aggregated data to a management entity.Type: ApplicationFiled: January 30, 2008Publication date: February 19, 2009Applicant: Telefonaktiebolaget LM Ericsson (publ)Inventors: Anna Pucar Rimhagen, John Quilty, Erik Lars Westerberg

Publication number: 20090047958Abstract: Methods and apparatus for maintaining neighbor cell information for use in handover operations are disclosed. In an exemplary method, a mobile station maintains a high-priority neighbor cell list and a low-priority neighbor cell list, each list comprising one or more neighbor cell entries corresponding to candidate cells for handover. Signal strength measurements for candidate cells in the high-priority list are made according to a first measurement schedule, while signal strength measurements for candidate cells in the low-priority list are made according to a second measurement schedule. In one or more embodiments, the low-priority cells are measured less frequently than the high-priority neighbor cells.Type: ApplicationFiled: January 24, 2008Publication date: February 19, 2009Inventors: Anna Pucar Rimhagen, Mikael Larsson, Erik Lars Westerberg
