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

Patent number: 7526289Abstract: The invention relates to a radio resource control method, a mobile communications system and a network element implementing the method. According to the invention, the cell change procedures performed by the user equipment in an idle state are controlled dynamically with control information that is adjusted according to a predetermined time pattern. The invention enables for instance an advanced cell change in an idle state, thus reducing the probability of a handover while the user equipment is in a dedicated connection to the network.Type: GrantFiled: October 23, 2002Date of Patent: April 28, 2009Assignee: Nokia CorporationInventors: Uwe Schwarz, Petteri Hakalin, Antti Tölli

Publication number: 20050083900Abstract: The present invention optimises and reduces the needed information exchange between network entities through the interfaces which connect them. The main property of the event based reporting method of the present invention is its flexibility because it is able to change the reporting rate depending on the value of the input parameter in each instant of time. That is, it sends more reports or less reports depending on if the parameter to be reported is changing quickly or slowly, respectively. The main idea of the present invention is that reports of a data network parameter are based on the relative change of the data network parameter value with respect to the previously reported data network parameter value.Type: ApplicationFiled: October 22, 2004Publication date: April 21, 2005Inventors: J.
