  • Patent number: 11451624
    Abstract: A virtual network manager system comprising a server in communication with a node, the server including at least one virtual network function (VNF), a cluster manager in communication with the server, the cluster manager is configured to detect a change in a health of the VNF on the server and when the change in the health of the VNF occurs generate a signal to a node to perform an action, the action including at least one of throttling traffic to the VNF, rerouting traffic to an alternate VNF, changing a weight value for traffic to the VNF, and generating an alert indicating a relative capacity change at the VNF.

  • Patent number: 11039291
    Abstract: Node identifiers can be assigned to packet core policy nodes and directly routed to a diameter routing agent (DRA) and application functions (AFs) within a call processing message that is employed to establish an application service. Such a policy node identity will be received by Application Functions, UEs and/or intermediate message routers during the initial establishment of a packet data session so that they can refer to the policy node entity directly in the sub-sequent call processing flows related the established session, instead of querying a relational database which can be complex to maintain with multi-million correlation records. As an example, the policy node identifiers can be configurable and can comprise a hostname of the policy nodes, address data associated with the policy nodes, or a defined numerical value that maps to the hostname of the policy nodes.

  • Patent number: 10880173
    Abstract: The described technology is generally directed towards automated acceptance testing of network functions so that only certified network functions are deployed in a wireless network. When a network function attempts to register in a network, e.g., with a network function repository, the registration attempt triggers a workflow that obtains a result of automated testing of the network function. The automated testing operation can be based on a test suite selected according to the network function type and the network slice in which the network function is to be deployed. Only upon determining that the network function passed the automated testing operation is the network function registered (by the network function repository) for operation in the wireless network.
