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.

System and method for dynamic bearer selection for immersive video collaboration in mobile wireless networks

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.

Facilitating packet flow in a communication network implementing load balancing and security operations

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.

System and method for providing security in a network environment using accounting information

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.

Service-based network access

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.

Virtual address translation to support wireless access to data networks

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.

Load balancing network access requests

Providing a quality of service for a mobile node includes facilitating a communication session for the mobile node. A quality of service decision factor of a context of the communication session is established. A quality of service associated with the quality of service decision factor is identified. Whether to provide the quality of service to the mobile node for the context is determined.

Dynamically providing a quality of service for a mobile node

A method for managing network access is provided that includes receiving a signal indicating a change in a network parameter, the change reflecting that an end user associated with a communication session has changed from using a first network node to a second network node. Each of the network nodes is operable to facilitate the communication session associated with the end user. The method also includes communicating with a billing system element to notify the billing system element of the change in the network parameter and receiving quota information for the end user associated with the second network node. The billing information associated with the second network node may be applied to the communication session, the billing information being based on the quota information.

System and method for managing network access for an end user

A method for providing security in a network environment is provided that includes receiving a flow that propagates through an access gateway, the flow being initiated by an end user associated with the flow and propagating through a network. Internet protocol (IP) address information may be gleaned from the flow at a network element. The method further includes recognizing a selected one of the end user being connected to the network and the end user being disconnected from the network such that the IP address information in the access gateway and the network element is substantially synchronized.

In a telephony communication system, a mobile device requests access to packet-based networks using network access requests that identify access point names associated with these networks. The mobile devices and gateways 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.

Virtual addressing to support wireless access to data networks

A method for relaying information in a network environment is provided that includes establishing primary and secondary packet data protocol (PDP) links on behalf of an end user and communicating traffic pattern information associated with the primary and secondary PDP links to a client services packet gateway (CSPG), the traffic pattern information providing data associated with how traffic flows propagating via each of the primary and secondary PDP links are to be treated in a network.

System and method for relaying information in order to enable services in a network environment

A method for enabling a service in a network environment is provided that includes establishing a communication link with an end user and evaluating signaling information associated with the communication link to identify a correlation between the end user and a multicast service group associated with the end user. The correlation may be used to provide one or more multicast services to the end user.
