Publication number: 20140293776Abstract: A method to balance idle UEs during RA procedures is described. The method includes determining a load condition of a first cell and a load condition of at least one neighbor cell and determining a suitability of the first cell for receiving access attempts from idle mobile devices based on the load conditions of the first cell and of the at least one neighbor cell. The method includes sending an indication of the suitability (for example, in a broadcast message and/or a UE specific message). A UE receives the indication of suitability. The UE selects a target cell from a plurality of cells based at least in part on the indication (for example, in order to select a target cell that is less loaded). The method also includes sending, from the UE, an access attempt to the target cell. Apparatus and computer readable media are also described.Type: ApplicationFiled: March 29, 2013Publication date: October 2, 2014Applicant: Nokia Siemens Networks OYInventors: Roy Yang, Weidong Yang, Ivan Vukovic

Patent number: 8849292Abstract: The present invention is related to configuration of uplink sounding reference signal transmissions in a modern cellular telecommunication system. A terminal device of a cellular telecommunication system is configured to apply a sounding reference signal configuration used for transmitting a dynamically scheduled sounding reference signal from the terminal device to a base station. In connection with the scheduling of the transmission of the sounding reference signal, the present invention utilizes a downlink control message transmitted to the terminal device regardless of whether or not uplink data transmission is scheduled to the terminal device at the same time.Type: GrantFiled: November 2, 2009Date of Patent: September 30, 2014Assignee: Nokia Siemens Networks OyInventors: Esa Tapani Tiirola, Kari Juhani Hooli, Kari Pekka Pajukoski

Patent number: 8842652Abstract: A relay node receives from user equipments UE CQI reports which give a CQI value per radio band resource RBR, from which are aggregated across the RBRs and/or aggregated per UE across that UE's RBR values. The relay node reports an indication of the average to its controlling access node (eNodeB), either explicitly or implicitly (e.g., a gain applied to the CQI of the downlink between the relay and access nodes). The relay node also checks the UEs' buffer status (actual or predicted) and reports either periodically or based on an underflow/overflow occurrence. For periodic reports, each UE buffer experiencing the overrun/underrun is reported.Type: GrantFiled: May 2, 2013Date of Patent: September 23, 2014Assignee: Nokia Siemens Networks OyInventors: István Z Kovacs, Bernhard Raaf, Oumer Teyeb, Vinh V Phan

Publication number: 20140254453Abstract: A wireless access node receives a first frame from a station through a first communication network such as an IEEE 802.11 network. The first frame comprises a source address identifying the station. The wireless access node applies a function to the source address to derive a destination address identifying an access controller coupled to the wireless access node through a second communication network such as an IEEE 802.3 network. The first frame is encapsulated in a second frame that comprises the destination address identifying the access controller and a source address identifying the wireless access node, respectively. The wireless access node sends the second frame to the access controller having the destination address through the second communication network. The access controller owns association and authentication state of the station, and shares the association and authentication state of the station with the wireless access node when needed to support desired service.Type: ApplicationFiled: March 5, 2013Publication date: September 11, 2014Applicant: Nokia Siemens Networks OyInventors: Jan Erik Johan BERGLUND, Zheng LI

Publication number: 20140248874Abstract: Improved systems and techniques for controlling access to network resources. A base station broadcasts extended access barring (EAB) and access class barring (ACB) information. Upon a determination by a user equipment that the user equipment requires service from the base station, the user equipment determines its EAB category and call type. The user equipment receives the EAB and ACB information broadcast by the base station and determines if it is subject to EAB based on its EAB category. If the user equipment is not subject to EAB, the user equipment determines if its call type is subject to ACB and, if the call type is subject to ACB, applies access class barring based on its call type.Type: ApplicationFiled: May 16, 2014Publication date: September 4, 2014Applicant: Nokia Siemens Networks OyInventors: Yi Zhang, Robert Zaus, Woonhee Hwang, Lei Du, Devaki Chandramouli
