Patent number: 9801037Abstract: The transmission of a warning message to a mobile terminal in a mobile communication network is triggered by an emergency event. The mobile terminal is first made aware of the need to receive a warning message by reception of an emergency event notification. The warning message is divided into a plurality of message segments. Each segment is transmitted in a separate paging message over a paging channel to mobile terminals in an idle mode. Information is added to each message segment to enable the mobile terminal to discriminate between segments belonging to different warning messages.Type: GrantFiled: October 17, 2016Date of Patent: October 24, 2017Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Paul Schliwa-Bertling, Anders Molander, Claes-Göran Persson, John Walter Diachina

Patent number: 9736742Abstract: 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: GrantFiled: October 5, 2015Date of Patent: August 15, 2017Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Angelo Centonza, Stefan Engström, Claes-Göran Persson, Paul Schliwa-Bertling

Patent number: 9357452Abstract: A telecommunications node (e.g., base station subsystem) and method are described herein that broadcasts a set of system information messages (e.g., SI2quater messages or pairs of SI2ter messages and SI2quater messages) for use by a legacy mobile station which enhances the overall probability (over time) that the legacy mobile station (non-supporting mobile station) in a network sharing scenario will find frequency, cell information or a combination of both within the broadcasted system information messages to be used for the legacy mobile station's cell reselection process to provide continuity with the legacy mobile station's registered PLMN (i.e. the Common PLMN of a shared radio access network). In addition, the telecommunications node (e.g., base station subsystem) and method can also broadcast a different type of system information message for used by a supporting mobile station.Type: GrantFiled: August 12, 2013Date of Patent: May 31, 2016Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Nicklas Johansson, John Diachina, Paul Schliwa-Bertling, Claes-Goran Persson
