Abstract: The described system and method enable user health monitoring and alerting by providing an arm-mounted sensor wirelessly linked to a wrist-mounted transponder, although the wrist-mounted transponder may be omitted in favor of a user-carried cellular device. In either embodiment of the invention, a remote server is included to receive user health data and alerts, and to log received data and, when necessary, to alert health service providers. Health service providers may include physicians and emergency services providers.

Abstract: This disclosure relates to methods and systems for monitoring network usage according to predetermined rules and calculating user charges based on the network usage. The described technique includes receiving a data packet, extracting parameters from the data packet and determining whether the extracted parameters match at least one rule in a rules engine. Charges for the data packet are calculated based on the matched rules. The data packet is forwarded on to its destination.

Abstract: A mobile station indicates a need for at least one specific type of Internet Protocol version 6 (IPv6) prefix in a message (73) transmitted to a serving network element. The latter processes this message to determine (74) the indicated IPv6 prefix type and responds with a reply message (75) comprising, at least in part, an IPv6 prefix of a type that is commensurate with the type (or types) indicated by the mobile station in the aforementioned message.

Abstract: Disclosed is a SIP client having a session initiation protocol module. A router that is capable of communicating with the SIP client, the router having a closest anycast IP server module. A SIP proxy server having an anycast address and a unicast address replacement module, the unicast address replacement module capable of replacing the anycast IP address of a received IP packet, that includes a session initiation protocol request message, with a unicast IP address of the SIP proxy server.

Abstract: A method and system for a mobile station to identify to a wireless network agent, an access point into a wireless network. The mobile station obtains an indication of an access point into the wireless network and inserts the indication into a mobile registration message. The access point identifier identifies an access point into the wireless network. Then, the mobile station sends the mobile registration message to the wireless network agent via the access point identified by the access point identifier. The wireless network agent receives the mobile registration message and provides the access point identifier to an authentication, authorization, and accounting (AAA) server. The AAA server uses the access point identifier to provide location-based services to the mobile station.

Abstract: A network access element (100) having an ability (11) of support communication sessions for a multi-stack Internet Protocol device is further preferably provided with an ability (12) to use a hang time in conjunction with at least one of the communication sessions. In a preferred approach, a network access element having an ability to support communication sessions for a multi-stack Internet Protocol device is further provided with an ability to update (38) corresponding accounting information.

Abstract: A mobile node using non-Mobile Internet Protocol version 6 is able to successfully communicate via Mobile Internet Protocol version 4 infrastructure via an encapsulating tunnel as is established between a first network element (such as a Packet Data Serving Node) and a second network element (such as a Home Agent). Extensions and/or codes can be conveyed via Mobile Internet Protocol version 4 Registration Requests/Responses that facilitate the automated establishment of, for example, a 6to4 tunnel for these purposes.

Abstract: A method and system for Mobile Internet Protocol (IP) device redundancy. As mobile devices roam away from a home network and change a connective status, mobility binding records are sent to a multicast network address on the home network. The multicast network address multicasts the mobility binding records to other active Mobile IP home agent control nodes, standby home agent control nodes and standby home agents on the home network. The method and system allows standby home agent control nodes or standby home agents to be transparently switched for active home agent control nodes or active home agents that fail without downloading or uploading large numbers of mobility binding records after a failure. The method and system may also help reduce failed calls (e.g., data sessions including Voice over IP (VoIP), H.323, etc.), network congestion and improve user satisfaction in Mobile IP systems.

Abstract: A home agent preference control node gathers information regarding available home agents in a given network. This information includes both information regarding present availability and other information (for example, other information as may pertain the relative availability of one home agent with respect to another). The home agent preference control node utilizes such information to determine a respective preference value for at least some, and preferably all of the network's home agents. Following communication of a resultant list that comprises, at least in part, such preference values, the home agents are then able to respond to home agent discovery inquiries from a mobile node with this information. This, in turn, facilitates selection by the mobile node of a home agent that likely represents at least a relatively efficient distribution of system resources.

Abstract: One or more Internet Protocol version 4 addresses are selectively modified (for example, by logical movement of a subnet boundary) to thereby alter the number of characters as comprise the address. This permits logical modification of a corresponding Internet Protocol 6to4 address prefix. This permits expansion or contraction of the logical size of the Internet Protocol 6to4 address prefix and hence permits creation and subsequent manipulation and use of corresponding pools of such address prefixes.

Abstract: A network element (10) can retain a plurality of prefix identifiers as are used to formulate an address to be used by individual network users. Pursuant to a preferred approach, one or more of these prefix identifiers are pre-correlated to a given domain name while at least one other prefix identifier is pre-correlated to the absence of a domain name. So configured, a specific prefix identifier can be allocated for use by a given network user as a function, at least in part, of the domain name (or lack of a domain name) as may be presented by that network user when seeking to establish a network connection.
