Publication number: 20140301399Abstract: The invention relates to methods for providing a network element 5 of a communications network with data, in particular HSDPA related data. In order to enable the transmission of user data, it is proposed that a controller 4 of the network uses a dedicated frame structure for assembling frames with said user data. The frames can then be transmitted from the controller 4 via an interface to the network element 5. In order to enable the transmission of control parameters, it is further proposed that an interface application protocol is employed which allows the controller 4 to add control parameters to control messages transmitted from the controller 4 to a network element 5 via the interface.Type: ApplicationFiled: June 23, 2014Publication date: October 9, 2014Applicant: CORE WIRELESS LICENSING S.A.R.L.Inventors: Sinikka Sarkkinen, Woonhee Hwang

Publication number: 20140269613Abstract: A method includes receiving at a UE information indicating different CN domains will be used for first and second data services after handover from a first RAT to a second RAT. Integrity protection is activated for the first and second CN domains but an element in the UE does not have an indication integrity protection is activated for the second CN domain. The UE provides a notification for the element that integrity protection has been activated for the second CN domain. Another method includes receiving at a network node a message indicating a UE has performed a handover involving first and second data services from a first to a second RAT, where the first and second data services will be handled by different core network domains. A security mode control procedure is performed to activate integrity protection towards the second core network domain. Apparatus and program products are disclosed.Type: ApplicationFiled: March 18, 2013Publication date: September 18, 2014Applicant: Nokia Siemens Networks OyInventors: Bindhya V.

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

Publication number: 20140044035Abstract: The present invention relates to methods and devices for enabling reception of a specific service for terminals idle mode. More particularly, the present invention relates to such methods and devices enabling mobility for terminals in idle mode so as to receive an MBMS service. In case a terminal is interested in the MBMS service, it applies different reselection rule than normal reselection rule i.e., when the terminal is not interested in the MBMS service. For instance, the terminal manipulates the priority indications received from an eNB and considers MBMS layer the highest priority in case the terminal is interested in MBMS service. If the terminal thus manipulates the priority due to the (intended) MBMS reception, the terminal starts an MBMS timer, which is received as a permission parameter from the eNB.Type: ApplicationFiled: April 28, 2011Publication date: February 13, 2014Applicant: Nokia Siemens NetworksInventors: Woonhee Hwang, Henri Koskinen

Publication number: 20130294415Abstract: The present invention relates to dynamic spectrum refarming with multiple carriers. At a first communication system of a first radio access technology, a request is received in a first signaling message from a second communication system of a second radio access technology, the request including information on availability of spectrum blocks shared between the first and second communication systems. The availability of the spectrum blocks may have been determined based on a load of the second communication system. The first communication system performs carrier aggregation mechanisms based on the information with respect to the spectrum blocks, and may transmit a response to the request in a second signaling message to the second communication system, the response including an acknowledgment of an activation/deactivation of at least one additional carrier and/or a corresponding carrier aggregation.Type: ApplicationFiled: November 30, 2010Publication date: November 7, 2013Applicant: Nokia Siemens Networks OyInventors: Jani Matti Johannes Moilanen, Antti Anton Toskala, Timo Erkki Lunttila, Sabine Roessel, Woonhee Hwang, Mikko Saily

Publication number: 20130281151Abstract: The long term evolution (LTE) of the third generation partnership project (3GPP) and the evolved universal terrestrial radio network (EUTRAN) may benefit from user equipment (UE) capability handling. For example, UE capability handling can benefit from feature group indicator (FGI) handling. A method according to certain embodiments can include processing a received set of feature group indicators from a user equipment. The method can also include determining whether the user equipment supports extended feature group indicators based on whether the extended feature group indicator bits are present. The method can further include determining that the user equipment does not support extended feature group indicators when the extended feature group indicator bits are not present.Type: ApplicationFiled: March 15, 2013Publication date: October 24, 2013Inventors: Jarkko Tuomo KOSKELA, Woonhee HWANG
