摘要： 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.

摘要： 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.

摘要： Systems and methodologies are described that facilitate communicating encapsulation information for a related mobility protocol type utilized in communicating over a data flow with reduced specific implementation on the policy server to support different mobility protocol types. In this regard, encapsulation information can be transmitted to the policy server from a network gateway such that the policy server can forward the encapsulation information to a serving gateway along with policy rules related to a data flow type. The serving gateway can utilize the encapsulation information to detect and interpret the encapsulated data flow according to the policy rules. In this regard, the serving gateway can provide support (e.g., quality of service support) for the flow. The encapsulation information can relate to a mobility protocol type, an encapsulation header, an indication that encapsulation is required, parameters regarding locating an encapsulation header in a message, and/or the like.

摘要： Systems and methodologies are described that facilitate inter-system handover in a wireless communication system. Various aspects described herein provide for handover techniques that enable a target system to be prepared by a mobile device via a source system in order to minimize specific changes required to source system and/or target system. Techniques are described herein in which the radio link of a source system can be utilized to tunnel signaling messages which are in a format understood by a destination node in a target system. Further, fast inter-access handover can be facilitated by establishing a simple generic transmission tunnel between respective network nodes in source and target systems that handle intra-system mobility and providing a Layer 2 (L2) tunneling mechanism over the radio interface of each involved system technology.

摘要： 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.

摘要： 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.
