  • Patent number: 7808947
    Abstract: Managing network service access includes receiving a packet data service request. The packet data service request is associated with a mobile subscriber and a service identifier that can bypass validation for accessing a traffic destination. Access is requested from an access node in response to the packet data service request. The access node maps a target access point to the mobile subscriber, where the target access point provides the mobile subscriber with access to the traffic destination. An access acceptance message is received from the access node, where the access acceptance message identifies the target access point. A packet data context is created by associating the target access point with the mobile subscriber to allow the mobile subscriber to access the traffic destination.

  • Patent number: 7643411
    Abstract: 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.

  • Patent number: 7536187
    Abstract: Supporting communication sessions at a mobile node includes determining at a mobile node an address for one or more interior network elements of a network system. A interior network element is distinct from an edge network element of the network system, and is operable to establish a communication session. An address for an interior network element is inserted into packets. The packets are sent from the mobile node to the interior network element to communicate directly with the interior network element. The communication session is established using the interior network element.

  • Publication number: 20090016292
    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.
