| 20090207757 | SYSTEM AND METHOD FOR PROVIDING LOCATION AND ACCESS NETWORK INFORMATION SUPPORT IN A NETWORK ENVIRONMENT - A method is provided in one example embodiment and includes communicating location and access network information for an end user to a policy and charging rules function (PCRF) element that is coupled to a network element. The network element receives packets for a communications flow from the end user if the flow is initiated through a wireless network and through a wireline network. In more specific embodiments, the location and access network information is used to initiate one or more applications for the end user. The method could also include communicating to an application function that the end user has attached to one of the networks, has been assigned an Internet Protocol (IP) address, and the location and access network information for the end user. | 08-20-2009 |
| 20090207759 | SYSTEM AND METHOD FOR PROVIDING A CONVERGED WIRELINE AND WIRELESS NETWORK ENVIRONMENT - A method is provided in one example embodiment and includes receiving packets for a communications flow from an end user that can conduct the flow through a wireless network and through a wireline network. The method also includes providing policy control for the end user at a network element that receives packets and resolves admission control decisions for the flow for the end user in both the wireless network and the wireline network. The network element providing Internet Protocol (IP) address assignment for the end user in both networks. In more specific embodiments, the method includes providing policy peering in both home and visited networks for the flow, providing access network information that indicates the type of access network being used by the end user, and network address translation (NAT) control for the user. | 08-20-2009 |
| 20090207823 | SYSTEM AND METHOD FOR PROVIDING SELECTIVE MOBILITY INVOCATION IN A NETWORK ENVIRONMENT - A method is provided in one example embodiment and includes invoking a mobile access gateway function based on an end user requesting an Internet Protocol (IP) address in a wireless or a wireline network. The invocation is selective such that the mobile access gateway function is invoked if the end user requires IP mobility services. The method also includes communicating with a gateway in order to obtain the IP address. The mobile access gateway function is coupled to a network element that receives packets for a communications flow from the end user that can conduct the flow through the wireless network and through the wireline network. | 08-20-2009 |
| 20090207843 | SYSTEM AND METHOD FOR PROVIDING NETWORK ADDRESS TRANSLATION CONTROL IN A NETWORK ENVIRONMENT - A method is provided in one example embodiment and includes receiving packets at a network element for a communications flow from an end user, the network element receiving the packets if the flow is initiated through a wireless network and through a wireline network. A network address translation (NAT) binding occurs for the end user at the network element, the NAT binding including an Internet Protocol (IP) address for the end user, the NAT binding being controlled by policy infrastructure coupled to the network element. The network element can be provided along a routing path for the flow (e.g., the IP session), irrespective of whether mobility services are used by the end user. The policy infrastructure can also support NAT control between home and visited networks with the visited network retaining control and privacy over the actual NAT elements being used. | 08-20-2009 |
| 20100088400 | INTERNET PROTOCOL ADDRESS MANAGEMENT FOR COMMUNICATING PACKETS IN A NETWORK ENVIRONMENT - A method is provided in one example implementation and the method includes identifying through a home bearer manager that an Internet Protocol (IP) address has been previously sent to an access terminal, the IP address being issued by a visited bearer manager as a result of the access terminal requesting registration in a visited network. The method further includes communicating the IP address to the access terminal in response to the access terminal registering in a home network. The registrations in the home and the visited network allow a plurality of packets to be communicated to the access terminal via the IP address. In more specific embodiments, the IP address serves as a care of address (CoA) address and a home IP address concurrently. The IP address can be exchanged via a mobile IP (MIP) exchange. The home and visited bearer managers are independent or interdependent. | 04-08-2010 |
| 20100150003 | System and Method for Provisioning Charging and Policy Control in a Network Environment - A method is provided in one example embodiment and includes requesting real-time transfer protocol (RTP) quality metrics to be generated by a network for a specific flow in the network. The method also includes recording the RTP quality metrics and reporting the metrics as accounting data associated with the flow. In more specific embodiments, the accounting data includes a correlator with application level accounting and the accounting data is used for quality monitoring and troubleshooting on a per-subscriber basis, on a per-flow basis, or on a per-call basis. An application function can request RTP quality monitoring with a trigger that identifies if a quality parameter reaches a certain threshold. | 06-17-2010 |
| 20110090815 | SYSTEM AND METHOD FOR PROVIDING A TRANSLATION MECHANISM IN A NETWORK ENVIRONMENT - An example method is provided and includes receiving a packet associated with a flow, determining a tunnel identifier for the flow, and determining a flow identifier for the flow. The method includes associating the flow identifier and the tunnel identifier to an Internet protocol (IP) address to generate a binding to be used for a network address and port translation (NAPT). In other embodiments, a routing decision is executed based on the binding between the identifiers and the IP address. The flow identifier can be a context identifier (CID), and the tunnel identifier can be a softwire tunnel ID. In yet other embodiments, the packet can be tagged as part of an encapsulation operation, which includes providing information about a network location at which the network address and port translation is to be executed. | 04-21-2011 |
| 20110103266 | SYSTEM AND METHOD FOR PROVIDING LOCATION AND ACCESS NETWORK INFORMATION SUPPORT IN A NETWORK ENVIRONMENT - A method is provided in one example embodiment and includes communicating location and access network information for an end user to a policy and charging rules function (PCRF) element that is coupled to a network element. The network element receives packets for a communications flow from the end user if the flow is initiated through a wireless network and through a wireline network. In more specific embodiments, the location and access network information is used to initiate one or more applications for the end user. The method could also include communicating to an application function that the end user has attached to one of the networks, has been assigned an Internet Protocol (IP) address, and the location and access network information for the end user. | 05-05-2011 |
