Patent number: 8090376Abstract: A method of selecting a cell for handover of a mobile station to another communication system. A command is sent to a mobile station from a first network element. The command includes a request to perform compressed mode measurements at the mobile station of a neighboring cell. The neighboring cell uses a different communication means than the first network element. Compressed mode measurement results are received from the mobile station at the first network element. The received compressed mode measurement results are weighted with indicators of a prioritized neighbor cell list to form a prioritized list. A second command is sent to the mobile station from the first network element. The second command includes a second request to decode identification codes at the mobile station based on the prioritized list. An indicator of a suitable cell from the prioritized list is received from the mobile station at the first network element.Type: GrantFiled: October 3, 2008Date of Patent: January 3, 2012Assignee: Intellectual Ventures I LLCInventors: Antti Tölli, Uwe Schwarz, Petteri Hakalin, Heikki Hirvonen

Patent number: 8005482Abstract: A method of performing compressed mode measurements for selecting communication means in a communication system. Statistics are collected on handovers from a cell in a communications system to a plurality of other cells in the communications system. A cell load of each cell of the plurality of other cells is weighted by a percentage of handovers from the cell to the respective one of the plurality of other cells. A threshold is determined based on the weighted cell loads. The threshold can be used to trigger a load based handover from the cell to one of the plurality of other cells.Type: GrantFiled: October 3, 2008Date of Patent: August 23, 2011Assignee: Spyder Navigations L.L.C.Inventors: Antti Tölli, Uwe Schwarz, Petteri Hakalin, Heikki Hirvonen
