  • Publication number: 20190124543
    Abstract: A method of controlling performance of a wireless device is performed by a node that is in electronic communication with a cellular network. The node includes a processor, a non-transitory memory, and a network interface. The method includes receiving a performance value characterizing a performance of a communication channel between a wireless device and a wireless access point. In some implementations, the wireless device and the cellular network are associated with different radio access technologies (RATs). The method includes determining whether the performance value breaches a performance criterion for the wireless device. The method includes adjusting a first amount of data transmitted to the wireless device from a base station of the cellular network and a second amount of data transmitted to the wireless device from the wireless access point. In some implementations, the combined first and second amounts of data satisfy the performance criterion for the wireless device.

  • Patent number: 9860768
    Abstract: Systems and methods for providing load based optimizations in communication networks are provided. A network device that provides network management and exchanges control messages with other network devices in the communication network can be modified to masquerade as a radio access transceiver to obtain radio access transceiver load information. The network device can be modified to include a radio-related interface and can communicate messages with the radio access transceivers to setup a radio access transceiver connection for exchange of load information. The radio access transceiver load information can then be used in the core network to provide optimizations for the loaded radio access transceivers. The optimizations can include modifying packet flows to decrease the bandwidth needed and switching one or more packet flows to another radio access transceiver.

  • Patent number: 9820253
    Abstract: Systems and methods for small cell idle mode mobility include receiving, at a first small cell of a preconfigured cluster of small cells, a mobility area update request from a user equipment (UE). The method can also include registering location information of the UE with a small cell gateway, and retrieving a core network periodic timer for the UE from a mobility server. If certain conditions are met, the first small cell forwards the mobility area update request to a core network via the small cell gateway. Otherwise, the method can include the first small cell updating the location information of the UE with the mobility server, generating a locally-generated mobility area update accept message, and sending a locally generated mobility area update accept message to the UE along with a local periodic timer instructing the UE to send another mobility area update request when the local periodic timer expires.

  • Patent number: 9769784
    Abstract: A serving gateway updates location information for a mobile device based on information in an update bearer request. The serving gateway receives a first update bearer request for a mobile device. The first update bearer request includes a first address associated with a micro cellular service base station to which the mobile device is in communication. The micro cellular service base station is associated with a physical location. The serving gateway sends a location notification to a location server, indicating that the mobile device is physically near the micro cellular service base station. The serving gateway receives a second update bearer request for the mobile device including an address associated with a macro cellular service base station. The serving gateway sends another location notification to the location server indicating that the mobile device is no longer at the physical location of the micro cellular service base station.
