20080304441 | MOBILITY MANAGEMENT MODE SELECTION IN MULTIPLE ACCESS WIRELESS NETWORKS - Systems and methodologies are described that facilitate indicating and determining mobility management modes in access identifiers for wireless communications networks. Wireless devices can indicate mobility management modes to be utilized by choosing a target system and communicating the chosen system and a home system to one or more network components.

20090047952 | IDLE MODE MOBILITY MANAGEMENT IN A MULTI-ACCESS SYSTEM USING PMIP - 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. | 02-19-2009 |
20090196231 | MOBILE IP MULTIPLE REGISTRATIONS AND PCC INTERACTIONS - 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. | 08-06-2009 |

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. | 08-06-2009 |

Further, a reverse query of a Domain Name Server (DNS) and a forward query of the DNS can be performed. The reverse query can be constructed based upon the previously registered IP address of the node and can resolve a name (e.g., string, . . . ). Further, the forward query can be formed based upon the name and can return a differing IP address of the node. | 09-24-2009 |
20090300207 | PCC ENHANCEMENTS FOR CIPHERING SUPPORT - Systems and methodologies are described that facilitate tunneling within wireless communication systems.

Different aspects relate to using source addresses in combination with the flow identification information for identifying different IP flows originating at a plurality of sources. The flow identification information also facilitates in verifying if different flows are transmitted in accordance with appropriate rules. The generated data flows are transmitted with respective flow identification information in order to facilitate the verification process. | 12-03-2009 |
20090303881 | METHODS AND APPARATUS FOR NETWORK CONTROLLED MOBILE IP FLOW MOVEMENT - Methods and apparatus for network controlled mobile IP flow movement. An infrastructure node, such as a home agent, signals a mapping between care-of-addresses (CoAs) and flows to be transmitted from a mobile device in uplink communications. The CoA associated with each flow is determined from network, device, and/or flow information. A mobile node or mobile gateway receives the mapping and updates its local policy information. When a selected flow is to be transmitted in an uplink transmission, the local policy information is used to determine the CoA associated with the selected flow. The CoA is then used to determine an access network (or access path) on which the uplink transmission of the selected flow is to occur. | 12-10-2009 |
