Patent number: 7916697Abstract: The invention relates to a method for supporting a handover of a mobile station 1 from a first radio access unit 3, 8 of a wireless communication network 2 to a second radio access unit 4, 9 of a wireless communication network 2. In order to improve a context transfer in the case of a handover of the mobile station 1, the mobile station 1 transmits information about its activity state to the second radio access unit 4, 9 when it is to be handed over to the second radio access unit 4, 9. The invention relates equally to such a mobile station, to such a second radio access unit, to a wireless communication system comprising such a mobile station and such a second radio access unit, and to a software code causing the transfer of information at the mobile station.Type: GrantFiled: August 17, 2004Date of Patent: March 29, 2011Assignee: Nokia CorporationInventor: Carl Eklund

Publication number: 20100002635Abstract: Piggy-backed requests for resources are handled in a packet-switched communications system. A terminal arrangement sends an access request to a network element in order to request permission to use communications resources for transmitting a data packet found in a transmission buffer of the terminal arrangement. Knowledge is established about a predicted data packet which is to appear in the transmission buffer of the terminal arrangement in the near future. The terminal arrangement transmits to the network element an access request for predicted traffic, requesting permission to use communications resources for transmitting said predicted data packet once it appears. This access request for predicted traffic is piggy-backed onto another transmission.Type: ApplicationFiled: January 12, 2005Publication date: January 7, 2010Applicant: NOKIA CORPORATIONInventor: Carl Eklund

Patent number: 7346041Abstract: The invention relates to an OFDM-transmitter, comprising means for transforming (400) data to be transmitted in frequency-to-time transformation to a basic waveform containing waveform components representing subbands of the spectrum of the signal. The transmitter comprises means for forming (402) at least one alternative waveform from components of the basic waveform, where at least one component in the alternative waveform is delayed in time, and means for selecting (414) a waveform for transmission from the group of waveforms, containing the basic waveform and the at least one alternative waveform. The invention also relates to a method for transmitting an OFDM signal, a method for processing an OFDM signal and an OFDM signal processing arrangement.Type: GrantFiled: December 9, 2004Date of Patent: March 18, 2008Assignee: Nokia CorporationInventors: Carl Eklund, Lars Lindh

Publication number: 20070258472Abstract: A system, apparatus and method for utilizing a first communication interface(s) to initiate communications via a second communication interface(s). Auxiliary communication information (104A) is communicated from an initiating device (100) to a target device(s) (110) via a first membership-based communication interface (112). In response to the auxiliary communication information (104A), an auxiliary communication module is activated at the target device (110) for communication via a second (over-the-air) OTA communication interface (116). The target device (110) may then communicate with the initiating device (100) and/or other devices (120) via the second OTA communication interface (116).Type: ApplicationFiled: September 6, 2004Publication date: November 8, 2007Inventor: Carl Eklund

Patent number: 7257590Abstract: The present invention relates to a method and network element for classification of bit strings such as data packets on a per-flow basis, wherein a plurality of classification fields are searched for in respective search trees based on a matching procedure in which an index value is obtained in a leaf node of a search tree for each classification field. Index values obtained in said searching step are used to derive a policy to be applied to said data packet, wherein the number of index values is reduced by combining intermediate results of the searching step or the deriving step. Thereby, computational efficiency can be improved and memory requirements reduced.Type: GrantFiled: August 29, 2001Date of Patent: August 14, 2007Assignee: Nokia CorporationInventors: Andreas Heiner, Carl Eklund

Patent number: 7058728Abstract: A method and apparatus for initiating compression of IP headers of a stream of packets to be sent from a source apparatus to a destination apparatus. IP header compression is initiated by changing the destination address of the IP header of a full header packet to identify the address of a node, such as a router, which serves as an interface to the destination apparatus, and passing the context identifier (CID) and generation fields in a routing header which immediately follows or is inserted to immediately follow the IP header.Type: GrantFiled: October 29, 1999Date of Patent: June 6, 2006Assignee: Nokia CorporationInventor: Carl Eklund
