  • Patent number: 11005704
    Abstract: A user equipment starts a first timer in response to detecting a physical layer problem with a radio link between the user equipment and a node of a cellular network. Responsive to detecting a handover measurement event, the user equipment also starts a second timer and sends a measurement report to the node. The starting of the first and second timers causes the first and second timers to simultaneously elapse. Responsive to one of the simultaneously elapsing timers expiring, the user equipment sends a radio link failure report, to the node, indicating which of the simultaneously elapsing timers expired.

    Abstract: A shared Radio Network Node, RNN, and a method for managing overload in a core network. The shared RNN is configured to serve a wireless device, and the wireless device and the RNN are operating in a wireless communications network connected to the core network. The RNN receives a connection request from the wireless device, wherein the connection request comprises a mapping parameter configured to map to an MME connected to the RNN. Further, the MME is logically partitioned into several MMEs and configured to support multiple MME Codes, MMECs, each of which MMECs is pointing at a sharing operator. The mapping parameter comprises an MMEC configured to map to one MMEC supported by the MME. Further, the RNN rejects or redirects the connection request when the MMEC configured to map to one MMEC supported by the MME is associated with an overload action.

  • Publication number: 20210084539
    Abstract: Radio network equipment (1700) is configured to implement a radio access network, RAN, central unit (12-C). The radio network equipment (1700) is configured to decide, by the RAN central unit (12-C), which of multiple RAN distributed units (12-D1, 12-D2) is to be responsible for activating duplication of traffic of a radio bearer (16) over multiple paths (16-1, 16-2). Different ones of the RAN distributed units (12-D1, 12-D2) serve different respective ones of the multiple paths (16-1, 16-2). The radio network equipment (1700) is also configured to transmit, from the RAN central unit (12-C), control signalling (20) to each of one or more of the RAN distributed units (12-D1, 12-D2) indicating whether or not the RAN distributed unit is responsible for activating duplication of the traffic of the radio bearer (16) over the multiple paths (16-1, 16-2).
