  • Patent number: 10855849
    Abstract: Apparatuses and methods concerning routing of calls in an IPBX server are disclosed. As an example, one apparatus includes a first processing circuit communicatively coupled to an IPBX server. The IPBX server is configured to generate call event messages for the VoIP calls routed by the IPBX server. The first processing circuit is configured to generate call summary metrics from the call event messages. The call summary metrics indicate respective sets of call data for participants of the calls routed by the IPBX server. A second processing circuit is configured to identify organizations associated with the participants of the calls. The second processing circuit aggregates call summary metrics of the participants associated with at least one identified organization and identifies, based on the aggregated call summary metrics, needs of the organization that can be satisfied by a set of capabilities of an entity.

    Abstract: Learning-based service migration in mobile edge computing may be provided. First, a service migration policy may be created for a network that includes a plurality of edge clouds configured to provide a service to users. Next, a movement of a user receiving the service from a source edge cloud may be detected. The source edge cloud may be associated with a first area and the detected movement may be from the first area to a second area. Then, the service migration policy may be applied to determine whether to migrate the service for the user from the source edge cloud. In response to determining to migrate the service, a target edge cloud may be identified and the service for the user may be migrated from the source edge cloud to the target edge cloud.

  • Patent number: 10798240
    Abstract: Apparatuses and methods concerning routing of calls in an IPBX server are disclosed. A first processing circuit is communicatively coupled to an IPBX server that routes VoIP calls for a plurality of end-users having respective VoIP-enabled devices and generates call event messages for the routed calls. The first processing circuit generates call summary metrics from the call event messages. A second processing circuit evaluates the call summary metrics to identify a set of incoming calls to the IPBX that were missed and have not been returned by the end-users. The second processing circuit cross-correlates the identified set of incoming calls with a secondary data source to determine a respective priorities for the set of incoming calls. The second processing circuit stores data indicating calls of the identified set have a higher priority.

  • Patent number: 10798585
    Abstract: A distributed controller of local radio resources implements a hybrid FFR system. The distributed controller provides user channel information to a central controller of regional radio resources. The distributed controller also obtains an FFR plan from the central controller. The FFR plan designates for an access point associated with the distributed controller, a central frequency band, an edge frequency band, and a distribution of user devices connected to the access point. The distribution indicates whether each user device communicates with the access point via the central frequency band or via the edge frequency band. The distributed controller provisions the access pint to connect to the user devices according to the FFR plan, and adjusts the distribution of user devices locally based on a change in the user channel information.
