In one embodiment, a network device receives an Internet protocol (IP) registration request, such as a mobile IP registration request, from an access terminal. The network device may be a home agent that is configured to register the access terminal for IP services at the network layer. In addition to registering the access terminal at the network layer, the network device may facilitate registration at another layer, such as the application layer. In one example, registration information for the access terminal for an application layer registration, such as information needed to register for a session initiation protocol (SIP) services, is determined. The network device then facilitates registration at the application layer automatically using the registration information.

This disclosure relates to a system and method for offloading selected data traffic in logical tunnels to the Internet. The offloading provides another data path for selected data traffic that can relieve the burden on a mobile operator's network, such as the backhaul and core networks. As the proliferation of data rich content and increasingly more capable mobile devices has continued, the amount of data communicated over mobile operator's networks has increased. Upgrading the existing network that was designed for voice calls is not desirable or practical for many mobile operators. This disclosure provides systems and methods for offloading data to the Internet at a router to relieve congestion on the mobile operator's network.

A method includes a network originating a QoS reservation message and communicating the network-originated QoS message through a radio access network (RAN) from an access gateway (AGW) to an access terminal (AT). The network-originated reservation message does not cause any network resource reservation by itself, but causes the AT to initiate a network resource reservation according to one or more parameters in the network-originated QoS reservation message. Accordingly, an existing network infrastructure supporting AT-originated QoS reservation may support network-originated QoS reservation (or proxied QoS) without any updates to an access-network infrastructure, such as the RAN. The method includes, in response to the network-initiated QoS reservation message, communicating a reservation confirmation through the RAN from the AT to the AGW. The reservation confirmation whether that the QoS reservation was successful.

Particular embodiments provide an access gateway that facilitates communication between a plurality of access technologies. The access gateway facilitates data communication with an access terminal through a bearer path. A radio resource manager is configured to provide radio resource management functions for the communications. The radio resource manager is decoupled from the bearer path and provides control of radio transmission characteristics for the bearer path to the gateway. Because the radio resource manager is not in the bearer path, the access gateway may be access technology agnostic. Thus, the access gateway does not need to have access-specific modules based on the radio technology for each bearer path.

Particular embodiments provide an optimal allocation of a bearer manager or home agent. In one embodiment, a message is received from a mobile node requesting access to a visiting network that is different from a home network for the mobile node. An authentication request is sent to the home network requesting authentication for access. The authentication request indicates that a home agent has not been assigned. The home AAA server then sends a response that indicates the visiting AAA server can assign a home agent for the mobile node. The visiting AAA server then assigns a home agent that is optimally determined. The visiting home agent is different from a home agent that is found in the mobile node's home network. When a registration request is received, an IP gateway may send the registration request to the visiting home agent, which may not be sent back to the home network.

An apparatus for charging in a network environment is provided that includes an access gateway encapsulation/decapsulation element operable to establish one or more packet data protocol (PDP) links on behalf of an end user and to perform encapsulation and decapsulation operations for one or more of the links associated with the end user. The access gateway encapsulation/decapsulation element is further operable to interface with a client services packet gateway (CSPG) that is operable to provide enhanced packet processing for the end user for requested information. The apparatus also includes an access gateway policy element operable to interface with the CSPG. The access gateway encapsulation/decapsulation element and the access gateway policy element cooperate to use one or more inter-module headers in order to coordinate the enhanced packet processing for one or more communication flows associated with the end user.

Network operators are striving to find ways to provide stable video services amid a rapid increase in video data traffic. In order to provide stable video services with constrained network resources, network operators attempted to reduce video file sizes and to cache videos for future use. However, network operators failed to exploit user information and to leverage benefits of distributing these functionalities across the network. This disclosure provides systems and methods for efficiently delivering video and managing video caches by exploiting user information and by distributing video delivery functionalities across the network.
摘要:
A method is provided in one example embodiment and includes receiving a data packet transported on a backhaul link at a first network element; identifying whether the data packet is an upstream data packet; identifying whether the data packet matches an internet protocol (IP) access control list (ACL) or a tunnel endpoint identifier; performing a network address translation on the data packet; and offloading the data packet from the backhaul link. In certain implementations, the method can include identifying that the data packet does not match the IP ACL or the tunnel endpoint identifier; and communicating the data packet to a second network element. In other instances, the method can include identifying that the data packet is a downstream data packet; and restoring a tunnel header and tunnel identification based on an IP address of the data packet.
