A method and system for providing access to Quality of Service levels from within a network to entities outside of the network.

Embodiments of the present invention provide systems and methods for a Session-level SDT component in the control plane to handle setup, recovery and mobility of individual session requests in real time. The Session-level SDT component may comprise path management that performs either stateless of stateful path switching for an ongoing session, whether download or uplink, according to the stateful requirements of the session. The path management may be in conjunction with user equipment mobility management operation; it may also be in conjunction with network scalability and automation operation, such as load balancing.

A technique for generating or updating a user profile based on a packet flow in a communications network from a user terminal to a destination address is described. A method implementation of this technique comprises receiving, by a Policy Control and Charging Rules Function (PCRF) from a Policy and Charging Enforcement Function (PCEF), at least one item of information indicative of at least one of the destination address and a service provided at the destination address to the user terminal. Based on this item of information, a user profile for a user associated with the user terminal is generated or updated.

Embodiments disclosed herein provide systems, methods, and computer readable media for recovering from media degradation during a communication session. In a particular embodiment, a method provides, during a communication session between a first user system operated by a first user and a second user system operated by a second user, receiving a first indication from the first user system indicating a degraded condition of media received by the first user system from the second user system. Responsive to receiving the indication, the method provides attempting to establish a connection with a third user system associated with the second user when the degraded condition comprises inactivity of the media being received by the first user system from the second user system. Upon establishing the connection with the third user system, the method provides connecting the third user system to the first user system to continue the communication session.

Network telephony monitoring systems are provided herein. In one example, a monitoring service is configured to present an interface for a network telephony monitoring system to receive link metrics for media legs of a packet voice call that extends from an originating network over a plurality of transport networks, with each of the media legs spanning between border control nodes of the plurality of transport networks. A leg quality processor is configured to process the link metrics to differentiate quality degradation of the packet voice call among one or more of the media legs.

VoIP networks and methods are disclosed for distributing media resources in a VoIP network for providing services. VoIP endpoints, media gateways, and/or other network nodes in the VoIP network report available media resources (i.e., available processing capacity) that are able to provide services, such as providing announcements, DTMF digit collection, etc, to a distributed resource server. The distributed resource server then assigns the available media resources among the VoIP endpoints and/or media gateways to perform services for calls in the VoIP network in order to distribute the tasks of performing services among different nodes of the VoIP network.

The present invention relates to methods and system for adaptive measurements applied to real time performance monitoring in a packet network. In particular, the present invention provides a method of real-time performance monitoring of a packet network by measuring by an agent of at least one performance metric. Measurement methodology can be adjusted in response to said at least one performance metric.

A method for cross-domain service optimization is implemented on a computing device and includes defining at least one key quality indicator (KQI) target for at least one end-to-end (E2E) service, where the at least one E2E service crosses more than one domain of a communications network, receiving an indication of quality of experience (QoE) for the at least one E2E service, based on the indication of QoE, translating the at least one KQI target to at least one set of service optimization instructions for each domain from among the more than one domain, and for said each domain, applying the service optimization instructions.

A method is provided for improving voice quality of Voice over IP networks in which a highest-quality routing protocol is interposed between a local IP PBX exchange and a cloud-based Internet service provider server to which calls are to be routed, wherein the highest-quality routing protocol detects the quality of the voice channel between the local IP PBX exchange and cloud-based Internet service provider servers and routes voice calls to that cloud-based Internet service provider server exhibiting the highest voice call quality, with the highest voice quality server connection determined by detecting lost packets and packet delay between the local IP PBX exchange and a server.

A system for providing small cell backhaul network communications includes a small cell backhaul network including a plurality of small cell network nodes each including transceivers for establishing wireless communication links with at least two other small cell network nodes and enabling communication with the at least two other small cell network nodes within the small cell backhaul network. The small cell backhaul network interconnecting an edge network with a core network through the plurality of small cell network nodes and enabling communication between the edge network and the core network over the wireless communications links. A software defined network (SDN) controller controls wireless communications links with each of the plurality of small cell network nodes. The transceivers at each of the plurality of small cell network nodes establish link configurations between the small cell network node and the at least two other small cell network nodes of the small cell backhaul network. A plurality of LTE interfaces, each associated with one of the small cell network nodes of the small cell backhaul network for provide control plane connectivity between the small cell network nodes and the SDN controller via a control channel and reduce SDN control latency.
