Publication number: 20170026882Abstract: According to an aspect, a network node operating in a first RAN according to a first RAT receives a handover request for a user equipment from a cell in a second RAN operating according to a second RAT. After handover of the user equipment to a cell in the first RAN is completed, the network node configures the user equipment to measure frequencies corresponding to the second RAN. Based on measurements reported by the user equipment for the frequencies, the network node identifies detected cells exceeding a measurement threshold, and sends a handover report towards the second RAN. The handover report includes, for at least one detected cell exceeding the measurement threshold, a physical cell identifier and a frequency identifier for the detected cell. The network node obtains configuration information for the detected cell, from another node, and uses the obtained configuration information for subsequent mobility procedures.Type: ApplicationFiled: October 5, 2015Publication date: January 26, 2017Inventors: Angelo Centonza, Stefan Engström, Claes-Göran Persson, Paul Schliwa-Bertling

Publication number: 20160353292Abstract: According to an aspect, a network node operating in a first RAN according to a first RAT is the target of an inter-RAT (IRAT) handover. The network node receives a handover request for a user equipment from a cell in a second RAN operating according to a second RAT. After handover of the user equipment to a cell in the first RAN is completed, the network node configures the user equipment to measure one or more frequencies corresponding to the second RAN. Based on measurements reported by the user equipment for the one or more frequencies, the network node identifies one or more detected cells exceeding a measurement threshold, and sends a handover report towards the second RAN. The handover report includes, for at least one detected cell exceeding the measurement threshold, a physical cell identifier for the detected cell and a frequency identifier for the detected cell.Type: ApplicationFiled: October 5, 2015Publication date: December 1, 2016Inventors: Angelo CENTONZA, Stefan ENGSTROM, Claes-Göran PERSSON, Paul SCHLIWA-BERTLING

Publication number: 20160321179Abstract: Interconnect circuitry and a method of operating the interconnect circuitry are provided, where the interconnect circuitry is suitable to couple at least two master devices to a memory, each comprising a local cache. Any access to the memory mediated by the interconnect circuitry is policed by a memory protection controller situated between the interconnect circuitry and the memory. The interconnect circuitry modifies a coherency type associated with a memory transaction received from one of the master devices to a type which ensures that when a modified version of a copy of a transaction target specified by the issuing master device is stored in a local cache of another master device an access to the transaction target in the memory must take place and therefore must be policed by the memory protection controller.Type: ApplicationFiled: April 30, 2015Publication date: November 3, 2016Inventors: Daniel SARA, Antony John HARRIS, Håkan Lars-Göran PERSSON, Andrew Christopher ROSE, Ian BRATT

Patent number: 8837399Abstract: System information transmitted from a wireless network is enhanced to contain additional information that indicates the relative priority between neighboring cells or frequencies in multiple Radio-Access Technologies, such as GERAN, UTRAN and E-UTRAN. In an example method implemented in a mobile station, a system information message of a first type transmitted by a base station is read. The mobile station determine whether one or more RAT priority bits are present in the system information message, wherein the presence or absence of the one or more RAT priority bits indicates whether additional ones of a plurality of available system information messages of the first type must be read before inter-RAT cell reselection may begin. If RAT priority bits are present, the mobile station selectively initiates inter-RAT cell reselection based on the one or more RAT priority bits.Type: GrantFiled: November 23, 2011Date of Patent: September 16, 2014Assignee: Telefonaktiebolaget L M Ericsson (Publ)Inventors: Thomas Johansson, John Walter Diachina, Henry Freberg, Claes-Göran Persson
