Publication number: 20120190335Abstract: Access verification is adaptively done using an identifier of a first or a second length, by comparing a field of a node address that has the determined first or second length against a locally stored access list. At least the compared field of the node address is either added to a locally stored list of cell selection candidate nodes where the access list is allowed identifiers, or excluded from it where the access list is restricted identifiers. The node identifier is in three sections. The first section is service type, which the UE can use to determine whether or not it is restricted/allowed. The first length is the length of the second section, which is a service area ID of a group of network nodes. The second length is the length of the second section plus the third section, which identifies one node of the group of network nodes.Type: ApplicationFiled: December 20, 2011Publication date: July 26, 2012Inventors: Lars Dalsgaard, Jarkko T.

Patent number: 7499701Abstract: The basic idea of the present invention is to specify at least two different triggers for sending a measurement report from the mobile station to the network. According to the invention, the network specifies the triggers to be used in different measurement report types. The triggers are preferably upper or lower threshold values for parameters of the radio signal. In response to having detected that the measured value has exceeded its upper threshold value or gone under its lower threshold, the mobile station sends the network a measurement report.Type: GrantFiled: December 2, 2005Date of Patent: March 3, 2009Assignee: QUALCOMM, IncorporatedInventors: Oscar Salonaho, Kari Sipila

Patent number: 7492740Abstract: The invention proposes a method for controlling a network comprising at least one cell served by a first type network device, wherein the first type network device is adapted to serve second type network devices, the method comprising the steps of detecting (S1) the downlink load of the cell in a direction from the first type network device to the second type network device, deciding (S2) whether the first type network device serving the cell is suited to serve sufficient service to second type network devices requesting service in the cell with respect to the detected downlink load, generating (S3) information as to the attractiveness of the first type network device based on the result of the deciding step, and providing the information to the second type network devices. The invention proposes also a device for controlling a network. By the method and the device, the load on a network can be more evenly distributed.Type: GrantFiled: April 6, 2001Date of Patent: February 17, 2009Assignee: Nokia CorporationInventors: Kari Sipilä, Uwe Schwarz

Publication number: 20080095133Abstract: The application discloses a method for avoiding inter-cell interference in a cellular communications system. In the method, a user terminal (UE2) measures (6-3) control signalling (6-2) of a first, serving base station (BS3) and control signalling (6-1) of a second base station (BS2), the user terminal (UE2) being within the coverage area of the serving base station (BS3) and the coverage area of the second base station (BS2). Based on the measuring, the user terminal calculates (6-4) a timing difference between the signalling from the serving base station (BS3) and the signalling from the second base station (BS2). Information on the timing difference is provided (6-5) to the serving base station (BS3). Based on the timing difference, the serving base station (BS3) schedules (6-6) data transmission (6-7) to be transmitted to the user terminal (UE2) non-simultaneously with the control signalling (6-1) from the second base station (BS2).Type: ApplicationFiled: October 23, 2006Publication date: April 24, 2008Inventors: Shu Kodo, Chen Hongyuan, Kari Sipila, Preben Mogensen

Patent number: 7167681Abstract: According to one embodiment of the invention, an antenna adjustment method, system and network element is provided. The system includes a mechanism for gathering information on interference in predetermined radio cells, a mechanism for arranging the gathered information radio cell-specifically for processing, a mechanism for determining a tilting factor for each predetermined radio cell, wherein the tilting factor relates to the interference the radio cell produces to other cells, and a mechanism for searching for the radio cells having the antenna tilting factors that fulfill a set criteria.Type: GrantFiled: August 27, 2003Date of Patent: January 23, 2007Assignee: Nokia CorporationInventors: Antti Kuurne, Ari Hämäläinen, Achim Wacker, Kari Sipilä

Patent number: 6982959Abstract: The present invention relates to defining triggers or threshold values for radio signal parameters that are used for determining whether or not to send a measurement report separately for the uplink and downlink direction. The triggers for the uplink and downlink are logically combined so that a measurement report may be sent when measurements in both the uplink and downlink satisfy the triggers, when either measurement does, or when only one of the uplink or downlink measurement does. Preferably, the measurement report is a mobile evaluated handover measurement report triggering a handover. It is preferably triggered in the mobile station when at least one upper threshold of the radio signal parameters for a mobile evaluated handover is exceeded or a lower threshold is gone under.Type: GrantFiled: February 9, 1999Date of Patent: January 3, 2006Assignee: Nokia CorporationInventors: Oscar Salonaho, Kari Sipila

Patent number: 6389294Abstract: The invention relates to a method of determining the average effect of radio wave multipath fading in a desired area in a radio system. The desired area of a coverage area of a base station in the system is described by a digital map. The average effect of multipath fading of a transmitter output is determined in different sub-areas of the desired area. In order to reduce the computation amount signal fading parameters are determined at some point of each sub-area by a ray tracing method and the average effect of signal multipath fading in the sub-area is calculated using said parameters.Type: GrantFiled: November 13, 1998Date of Patent: May 14, 2002Assignee: Nokia Telecommunications OyInventor: Kari Sipilä
