  • Patent number: 8787249
    Abstract: In a wireless communication system having multiple access nodes, a home agent (HA) maintains home address (HoA) for a mobile node so that an IP session can be established. As the mobile node moves within a coverage area of various access nodes, the mobile node can establish a secure relationship with a local access gateway and thereby register a local IP address, referred to as a care-of-address (CoA), with the HA. Mobile IP protocol can be established so that multiple sessions can be conducted. In maintaining policy and charging control (PCC), HA informs a policy and charging rules function (PCRF), which in turn can then send the appropriate PCC rules (e.g., IP flows and related policies) to a policy and charging enforcement function (PCEF) for a particular access gateway. Coordination necessary to associate CoA and HoA can further include filter information as to application can run on a particular interface.

  • Patent number: 8681683
    Abstract: Providing for inter-system idle mobility management for independent mobile networks is described herein. By way of example, registration of multiple mobile IP (MIP) addresses to a mobile device can be utilized to facilitate inter-system device tracking. An Internet Protocol (IP) home agent that serves the mobile device can associate the MIPs with a home IP address of the mobile device. When communication is received for the home address, device paging can be initiated by utilizing at least a plurality of the MIPs bound to the home address. A mobile device response can provide a current active network address, and the received communication can be delivered via such active network address. As disclosed herein, the mobile device can switch attachment among the networks without signaling such networks, based on the multiple address bindings. Accordingly, significant power reduction can be afforded to mobile devices in idle mode.

  • Patent number: 8626161
    Abstract: Systems and methodologies are described that facilitate enabling multiple address access between two or more networks. A home agent can update a binding cache with a particular proxy binding update (PBU) to include two or more network gateway IP addresses associated with a user equipment (UE) within two or more networks or systems. When the UE in idle mode moves between networks or systems to which registration has occurred, an attachment procedure is not performed since the home agent includes the network gateway IP addresses related to such UE. Thus, inter-system idle mode mobility is enabled without having to perform a full attachment, re-registration, or de-registration based on the network location of the UE.

  • Patent number: 8228935
    Abstract: Systems, methodologies, and devices are described that enable communication devices, such as mobile devices, to efficiently connect and communicate with public data networks (PDNs) even if overlapping Internet protocol address spaces exist in the PDNs. The subject innovation can employ virtual home agents (v-HAs) that can respectively serve PDNs. To facilitate connection of a mobile device to a desired PDN, a message, including an identifier relating to the desired PDN, can be transmitted to a v-HA and it can be discovered whether that v-HA serves the desired PDN; if so, the v-HA transmits the message to a “home” home agent (h-HA) associated with the desired PDN; and if not, the v-HA can transmit a switch message indicating the correct v-HA to which the message should be sent. Concatenation of communication tunnels associated with the correct v-HA and h-HA facilitate efficient communication associated with the mobile device and desired PDN.

  • Patent number: 8155020
    Abstract: Techniques for supporting policy control and charging (PCC) functions in a wireless communication network are described. In one design, a Policy Control and Charging Rules Function (PCRF) may receive a request from a first network entity (e.g., a home agent) to establish a PCC session for a user equipment (UE) accessing the first network entity using a mobility protocol (e.g., Mobile IP). The PCRF may determine the mobility protocol used by the UE based on an IP-CAN Type parameter included in the request. The PCRF may determine PCC rules for the PCC session based on the mobility protocol and may send the PCC rules to the first network entity. The first network entity may apply the PCC rules on packets for the PCC session and may count each packet for charging. A second network entity may forward the packets but would not count these packets for charging.
