Patent number: 9813947Abstract: The invention relates to the Authorized Shared Access (ASA) concept in which a source node temporarily uses ASA spectrum as secondary user and on request of an ASA controller said ASA spectrum needs to be cleared (evacuated) and made available to a primary spectrum user and thus target nodes have to be selected by the source node to take over traffic from the source node; the source node thus obtains resource information of at least one target node for the spectrum clearance, choose at least one target node for clearance traffic transfers based on the resource information of the at least one target node, inform the chosen at least one target node about the coming traffic transfers, and transfer traffic by using a handover procedure; the target node reserves resources after receiving the information about the coming traffic transfers.Type: GrantFiled: June 29, 2012Date of Patent: November 7, 2017Assignee: Nokia Solutions and Networks OyInventors: Jian Feng Qiang, Simone Redana, Vinh Van Phan

Patent number: 9647819Abstract: The present invention addresses a method, including configuring a remote device (UE) for measurements of at least one carrier in a first frequency band which is different from a second frequency band which is licensed used for communication by said remote device, receiving a measurement report from said remote device, and deciding on the usability of the at least one measured carrier in said first frequency band for communication by said remote device. Also, a method is proposed, including measuring at least one carrier in a first frequency band which is different from a second frequency band which is licensed used for communication by a remote device, and sending, to a network transceiver device, a measurement report of the measurements. Likewise, corresponding computer program products as well as correspondingly configured devices are addressed.Type: GrantFiled: August 18, 2011Date of Patent: May 9, 2017Assignee: Nokia Solutions and Networks OyInventors: Yong Teng, Chunli Wu, Jian Feng Qiang, Jie Zhen Lin

Patent number: 9516645Abstract: The disclosure relates to use of carriers for aggregation in a wireless system. A set of carriers available for use in carrier aggregation is first determined. It is then determined if at least one carrier of the set of carriers can become unavailable for use by a communication device. An indication of a configuration type of the at least one carrier is sent to the communication device, the configuration type being indicative of different behavior during a period. The at least one carrier is maintained in the set of carriers during said period. The communication device receives the indication. If a change in the availability state of the at least one carrier is determined, the communication is operated, device in relation to the at least one carrier, according to the availability state and the received indication during said period.Type: GrantFiled: March 25, 2011Date of Patent: December 6, 2016Assignee: Nokia Solutions and Networks OyInventors: Jie Zhen Lin, Jian Feng Qiang, Yong Teng, Chunli Wu

Patent number: 9301301Abstract: A Network entity of a communication network and a network node are disclosed. The network entity includes a control unit, wherein the control unit is configured for receiving network status information and providing a refarming control signal to a network node on the basis of the network status information. The refarming control signal is related to a reuse of a frequency resource of a first communication technology by a second communication technology. For evaluation of frequency refarming, a concept of a figure of merit is disclosed which allows for an easy employment of a frequency refarming policy.Type: GrantFiled: April 26, 2010Date of Patent: March 29, 2016Assignee: Nokia Solutions and Network OyInventors: Ottmar Aumann, Jian Feng Qiang
