  • Patent number: 8755342
    Abstract: The disclosure relates to managing the video and audio streams of a video collaboration session in a communication network. Specifically, the streams of the video collaboration session are managed by primitive messages that are sent in-band with the data of the stream. These in-band primitives are then used to modify the wireless bearers or channels that are carrying the streams to a mobile device. The mechanism can dynamically adapt the wireless bearers based on the primitives to ensure characteristics such as Quality of Service and packet loss are within certain parameters while minimizing the resources used to provide the specified service.

  • Patent number: 8427956
    Abstract: Facilitating packet flow in a communication network includes receiving at a defender a request packet sent from a node. The request packet is communicated to a load balancer operable to communicate the request packet to a network element server selected from a plurality of network element servers. The request packet has a destination address associated with the load balancer. A response packet is received from the network element server. The response packet has a tunnel endpoint address. Whether the tunnel endpoint address corresponds to an approved network element server is determined. The response packet is communicated to the node if the tunnel endpoint address corresponds to an approved network element server.

  • Patent number: 8312530
    Abstract: According to one embodiment of the present invention, there is provided a method for providing security in a network environment that includes receiving a flow that propagates through an access gateway. The flow is initiated by an end user associated with the flow and propagates through a network. The method also includes receiving accounting information indicative of the termination of the flow. In response, tearing down of the communication associated with the flow is initiated.

  • Patent number: 8166537
    Abstract: In a telephony communication system, an operator network provides access to data networks through gateways. The gateways provide access in response to network access requests from equipment such as mobile devices. The mobile devices and gateways providing access to the networks support service-based network access requests. These service-based network access requests permit networks to manage user access based on particular services requested.

  • Patent number: 8068817
    Abstract: In a telephony communication system, mobile devices request access to packet-based networks using network access requests that identify access point names associated with the networks. The mobile devices and an operator network providing access to the networks support the use of virtual access point names within network access requests. These virtual access point names need not correspond to any existing networks. Rather, network access requests incorporating virtual access point names indicate actually requested access point names within other fields of the network access requests.

  • Patent number: 8046430
    Abstract: A method of load balancing network access requests comprises receiving a network access request from a serving node linked to a radio access network. The network access request identifies a mobile node receiving wireless service from the radio access network and identifies a data network to which the mobile node has requested access. The network access request requests a communication channel with the serving node for transporting data communications between the mobile node and the data network. The method further comprising determining one or more gateways providing access to the data network, selecting one of the gateways, and forwarding the network access request to the selected gateway.
