  • Publication number: 20220245657
    Abstract: This application relates to apparatus and methods for generating target labels from multi-dimensional time series data. In some examples, a computing device receives parameters that correspond to each one of a plurality of sellers, and gathers a set of relevant time series metrics for each one of the sellers based on the respective seller's parameters over a time period. The computing device calculates aggregated metrics for each corresponding subperiod based on each seller's respective set of relevant time series metrics. The computing device generates seller persona clusters based at least in part on the calculated aggregated metrics for each seller. The computing device calculates a score for the generated seller persona clusters, and when the score is greater than or equal to a predetermined threshold value, generates a respective target label for each of the clusters, and applies each respective target label to the sellers within each respective cluster.

  • Patent number: 10171514
    Abstract: A method for routing media calls over a real time packet switch connection includes providing a session controller for connecting to a network. The method further includes providing a signaling switch for connecting to the session controller. The method further includes controlling call routing in the network with the session controller where the call routing control includes identifiers for elements in at least two layers of a seven layer model. The call routing control includes a preference for a codec for the call. The call routing is carried out taking into consideration a mean opinion score qualifier from previous calls having a same source and destination.

  • Patent number: 9871829
    Abstract: A voice over Internet protocol communication system and method provides infrastructure components as intermediaries between networks, the components include multi-protocol session controllers and a multi-protocol signaling switch as well as a management system. The session controllers process calls and participate in the calls that flow through it. The session controllers process calls that are either at the edge of the network or at the core of the voice over Internet protocol network. The session controllers associate calls with one another in call peers for incoming calls as ingress call peers and for outgoing calls as egress call peers. A centralized database of call routing policies is provided to the session controllers. The session controllers provide cost management, topology hiding, and inter-working, or conversion, of calls from SIP networks to H.323 networks for both voice and video.

  • Patent number: 8547962
    Abstract: A session controller configured to be coupled to a communications network is disclosed. The session controller is configured to receive an indication of a Voice over Internet Protocol (VoIP) registration request at a first time from an endpoint having a third-party registration, and to receive a signaling message from the endpoint at a second time later than the first time. The session controller is further configured to forward an indication of the VoIP registration request and a signaling message to an application server, such that at least a portion of the topology of the communications network beyond the session controller is hidden to the endpoint.

  • Patent number: 8254265
    Abstract: A session controller configured to receive a data packet from a packet-switched network having multiple communication links is disclosed. The disclosed session controller is further configured to define a call-routing policy based on layer-five information, layer-two information, layer-three information and layer-seven information from the data packet. The call-routing policy is configured to define a least-cost routing (LCR) call route for an ingress call over at least one of the plurality of communication links. The LCR call route is associated with an operational cost that is lower than an operational cost associated with at least one other call route over at least one communication link from the plurality of communication links. The session controller is also configured to associate the ingress call to an egress-call peer based on the call routing policy.

  • Patent number: 7865612
    Abstract: A method and apparatus for partitioning resources within a Session-over-Internet-Protocol (SoIP) Session Controller (SC) are described. In one illustrative embodiment, an apparatus comprises data access logic configured to receive an instruction to define at least one virtual partition in a SoIP SC, grant a primary entity access to data associated with each virtual partition, and grant each secondary entity from a plurality of secondary entities exclusive access, relative to the remaining secondary entities from the plurality of secondary entities, to data associated with a virtual partition associated with that secondary entity; and session administration logic configured to generate, for each SoIP session traversing a given virtual partition, a session data record (SDR) uniquely associated with that given virtual partition.
