  • Patent number: 10470044
    Abstract: User equipment (UE) within dual connectivity (DC) architecture with a Master Node-B (MN) and a Secondary Node-B (SN) includes processing circuitry decoding connection reconfiguration information from the MN. The connection reconfiguration information includes signaling radio bearer type 3 (SRB3) configuration information. The SRB3 configuration information originates from the SN and configures a SRB3, the SRB3 for a radio resource control (RRC) connection between the UE and the SN. An RRC connection reconfiguration request message received from the SN via the SRB3 is decoded. The RRC connection reconfiguration request message includes UE new radio (NR) security capability information of the SN. The processing circuitry further determines whether the UE NR security capability information received from the SN matches UE NR security capability information received by the UE from the MN.

  • Publication number: 20190182897
    Abstract: User equipment (UE) includes processing circuitry. To configure the UE for enhanced coverage (EC) in a 5G network, the processing circuitry is to encode N1 configuration request signaling for transmission to an Access and Mobility Function (AMF) of the 5G network. The N1 configuration request signaling includes an EC support capability indication of whether the UE supports restriction for EC. An N1 configuration response signaling is decoded from the AMF, the N1 configuration response signaling including EC restriction information. The EC restriction information is determined based on the EC support capability indication and subscription information of the UE. An enhanced coverage restriction determination is performed using the EC restriction information. A cell is selected from a plurality of available cells within the 5G network based on the enhanced coverage restriction determination.

  • Publication number: 20180376373
    Abstract: Methods, apparatus circuitry, and storage media are described for mobile-terminated packet transmissions. In one embodiment, an apparatus of a control plane device configured to operate within an evolved packet network core identifies a first service flow event trigger associated with a first packet data unit (PDU) session and processes a path reselection for a first PDU session in response to the first service flow event trigger, wherein the path reselection determines a new gateway for the first PDU session resulting from the path reselection. Transmission of a change notification to an application server controller associated with the first PDU session is initiated in response to the path reselection. Transmission of a routing update to the new gateway in response to the path reselection is also initiated. In various embodiments, the trigger may be a mobility event, a load balancing event, or operations in association with an application server controller.

  • Publication number: 20180317121
    Abstract: An SDN architecture, for a cellular communications system, is described herein that includes a Quality of Service (QoS) provisioning framework to provision and manage traffic flows in the cellular communications system. The described architecture separates the control plane and the user plane for the transport of the user plane traffic. Network entities in the SDN architecture, such as a network controller, can detect and react to changes in network state (e.g., load conditions) to route or reroute traffic flows in the network. QoS and routing parameters may be determined for the network traffic on a per-flow basis, even when multiple flows are associated with a single service request.

  • Patent number: 9585123
    Abstract: The present disclosure proposes a UE, a base station, and a MTC-IWF for implementing MTC group trigger messages through a Cell Broadcasting Service (CBS). The method includes a MTC (Machine Type Communication) server transmitting to a MTC Inter-working Function (MTC-IWF) a trigger payload. The trigger payload would be delivered by the MTC-IWF to a group of MTC devices through Cell Broadcasting Center (CBC) and network nodes. The trigger payload may include a group trigger message indicator which distinguishes the group trigger message from a normal warning message. In response to receiving the content of the trigger payload, the network would page a group of MTC devices. From the group trigger message indicator embedded in the paging message, each MTC device would be able to receive a group trigger message through new system information block of the broadcast information.
