  • Patent number: 10897418
    Abstract: Aspects of the disclosure relate to mechanisms for interworking between legacy and next generation radio access technologies (RATs) in a communication network. In some examples, a connectivity request originated by a user equipment towards a next generation core network may be processed by the next generation core network. The next generation core network may then provide the user equipment an indication of whether the next generation core network supports an inter-RAT handover between the next generation RAT and a legacy RAT.

  • Patent number: 10880809
    Abstract: In one embodiment, an interference-management system of a multi-hop wireless network may access an interference map indicating interference among network nodes, each network node comprising sectors that each comprise an array of beamforming antennae. The interference-management system may identify links between network nodes, each link being associated with a transmitting (TX) beamforming weight variable and a receiving (RX) beamforming weight variable. The interference-management system may generate a factor-graph representation of the multi-hop wireless network comprising a first set of vertices corresponding to a second set of vertices, each vertex pair being associated with an identified link, wherein each vertex pair comprises a variable node and a function node, and wherein messages passed between the nodes of a first vertex pair are derived at least in part based on messages previously passed between the nodes of one or more vertex pairs.

  • Patent number: 10813002
    Abstract: When a capillary network device connects to user equipment and the user equipment establishes or modifies a bearer to support traffic from the capillary device, the user equipment may request that the network provide some indication that the user equipment will not be charged for the traffic. The network may indicate to the user equipment that the flow is sponsored or that the user equipment will otherwise not be charged for the flow. Existing messages between a UE/GW, P-GW, PCRF, and an application server (AS) may be modified and new messages may be used so that the user equipment can request a guarantee of sponsorship or of non-charging and so that the AS may indicate to the user equipment that the flow is sponsored. The messaging can also be used by user equipment on its own behalf.

  • Patent number: 10798001
    Abstract: A data center interconnection (DCI) network may comprise a data center controller (DCC) managing a plurality of data centers (DCs) interconnected by a provider network managed by a network provider controller (NPC). The provider network may be an OpenFlow based software defined networking (SDN) transport network. The DCC may initiate a virtual network service (VNS) negotiation with the NPC to connect the DCs and may specify a network abstraction granularity level. The NPC may respond by computing paths through the provider network accordingly and providing the DCC with one or more virtual networks (VNs). The DCC may compute virtual paths through the VNs and send virtual network element (VNE) connection setup commands to the DCC.

  • Patent number: 10798584
    Abstract: A method, system and device for allocating resources of a base station node (Node B) are disclosed to enable F-DPCH resources of a local cell to be sufficiently used. In this invention, Node B reports to the RNC the F-DPCH capability of the local cell so as to provide a decision-making basis about using or not using the F-DPCH to the RNC. If the local cell supports F-DPCH, when the UE initiates an RRC connection establishment request, the RNC instructs the Node B to distribute the F-DPCH and HSDPA resources to the UE, otherwise the RNC instructs the Node B to distribute DPDCH and DPDCCH resources to the UE. The F-DPCH capability of the local cell can be reported in a newly added IE or extended existing IE of the Audit Response message and Resource Status Indication message.

  • Patent number: 10791218
    Abstract: A communication session (e.g., voice or video) is established between a first party and a second party. The communication session is placed on hold or mute by the second party. While the first party is on hold or mute, an event associated with the second party is detected. For example, the second party calls a third party. In response to detecting the event associated with the second party, a progress update message is sent to first party on hold or mute. For example, the progress update message may be a voice message that states the second party (e.g., the contact center agent) is talking to a third party to resolve an issue of the first party. By sending the progress update message, the first party is apprised of the second party's progress in assisting the first party.

  • Patent number: 10779339
    Abstract: Systems, methods, and computer-readable storage media for wireless roaming are disclosed. An access point receives a communication request from a wireless device and determines a home broadcast domain associated with the wireless device. The access point determines that the home broadcast domain is different than the broadcast domain associated with the access point and proceeds to identify a second access point that is associated with the home broadcast domain of the wireless device. The access point establishes a tunnel between the access point and the second access point for routing traffic associated with the wireless device.

  • Patent number: 10771985
    Abstract: Methods are provided to perform multiple-connectivity operation in the heterogeneous network. In one novel aspect, multiple-connectivity is configured with one microwave macro cell and multiple small cells. UE establishes control plane connectivity with the microwave macro cell, where the S1-MME interface is terminated. Multiple small-cell base stations provide traffic data together to the UE and are connected with Xn interfaces. One small-cell base station in the set of the configured small base stations is an UP anchor small-cell base station, where S1-U interface is terminated. Other small base stations are UP assistance small base station. In one embodiment, the set of small base stations and the UP anchor small base stations can be changed based on the measurement report/results of the different cells as well as the cell loading status. The anchor base station can be changed either by the UE or through network configuration.
