A wireless system receives a registration from a user device and transfers a request for the user device to an authorization server. The authorization server authorizes a user session for the user device and transfers a common identifier for the user session to the wireless system. The wireless system receives the common identifier and transfers a registration for the user device to an application node. The application node receives the registration and transfers a request for the user device to the authorization server. The authorization server authorizes a user application for the user device and transfers the common identifier for the user application to the application node. The wireless communication system tracks the user session and transfers user session data records having the common identifier. The application node tracks the user application and transfers user application data records having the common identifier.

Maintaining a common identifier for a user session on a communication network

A user, identified by a network access identifier (NAI) or other user identifier, uses a communication device, identified by a hostname or other device identifier. An Internet Protocol (IP) address is obtained for the communication device, e.g., when the user logs in for access to a packet-switched network. An association between the IP address and the hostname is registered in a domain name server. An association between the user identifier and the hostname is registered in an RWHOIS server. An application may query the RWHOIS server to determine the hostname of the communication device being used by the user and then query the domain name server to determine the IP address of the communication device.

Method and system for associating a user identifier with a device identifier

Ways for performing servicing a service request from a communications device that is normally associated with a first domain are disclosed. An illustrative method includes dynamically assigning a CSCF (Call Session Control Function) associated with a second domain to receive service requests from the device in an IMS (IP Multimedia Subsystem) networking environment, receiving the requests by way of the dynamically assigned CSCF.

Dynamic CSCF assignment

Systems and methods for assigning unique network identifiers in a packet-switched wireless network are provided. A request for a unique network identifier for a wireless device is received. A socket-based unique network identifier, including an IP address and one or more ports, is assigned to the wireless device. The unique network identifier is created by combining an IP address and one or more ports. This allows multiple unique network identifiers to be created from a single IP address, where each unique network identifier consists of the same IP address combined with a different group of one or more ports.

Socket-based internet protocol for wireless networks

A portable electronic device is provided comprising a processor, a memory, a display, and an application stored in the memory that, when executed by the processor, initiates a plurality of user agents that each indicate a different communication point. The portable electronic device also transmits a request for a content from each of the user agents to a content source, the requests being transmitted substantially concurrently. The portable electronic device also receives a plurality of contents, each content associated with one of the user agents and each content formatted differently than the remaining contents. The portable electronic also presents one of the contents on the display, wherein the portable electronic device promotes concurrent downloading of a content in multiple formats from the content source.

Parallel multiple format downloads

Computer-readable media, systems, and methods for geographically appropriate domain name system assignment are described. In embodiments, a mobile internet protocol session is initialized with a packet data serving node, and a registration request is communicated to a home agent, the home agent acting as a router on a home network of the mobile device and enabled to tunnel one or more data packets to the mobile device when the mobile device is outside the home network. Further, in embodiments a registration reply is received from the home agent, the registration reply including a domain name system server assignment to a domain name system server acting as a translator capable of converting one or more hostnames into one or more associated IP addresses during the mobile IP session.

Geographically appropriate domain name system assignment

A method, system, and computer-readable media are provided for allowing a mobile device to maintain communication connectivity during a handoff between wireless access points. In one aspect, the method may include negotiating security association information and establishing a first communication tunnel by tunneling an inner IP address within a first outer IP address. The method may further include authenticating a request for establishing a second communication tunnel by identifying the negotiated security association information within the request. Additionally, the method may include establishing the second communication tunnel by tunneling the inner IP address within a second outer IP address. Moreover, the method may include pushing data associated with the communication session through the second communication tunnel.

Mobile device handoff while maintaining connectivity with multiple access points

A communication system automatically provides a secure communication link between a device and a network. A switch initiates a wireless link between the switch and the network. Then, a secure communication path is created between the switch and the network. When a device is linked to the switch, the device is automatically granted access to the secure communication path created by the switch.

System and method for establishing a secure wireless communication path

A method and corresponding device and system to provide a real-time call announcement to a called device. According to the method, a called device begins receiving call announcement media without having first engaged in session setup signaling to set up a session through which to receive the call announcement media. In normal operation, the device would disregard such incoming media, since no session has been set up for receiving the media. As disclosed, however, the device will also receive at about the same time a call setup request that seeks setup of the underlying call, and the device will treat its receipt of that call setup request as a key to allow playout of the call announcement media even though no session has been set up for receipt of the call announcement media. The called device will then play out the call announcement media as an announcement for the call.

Method, device, and system for real-time call annoucement

Systems and methods are provided for an optimized mobile-IPv6 encapsulation. A mobile node sends packets to a correspondent node by encapsulating a packet using an IPv6 routing extension header, and reverse tunneling the packet to a home agent. The home agent modifies the packet and forwards it to the correspondent node. When the correspondent node sends packets to the mobile node's home address, the home agent intercepts the packet, encapsulates the packet with an IPv6 routing extension header, and tunnels the packet to the mobile node. Consequently, because packets are tunneled using IPv6 routing extension headers, the amount of overhead in each encapsulated packet is reduced, thus increasing the available bandwidth in a network.

Mobile-IPv6 encapsulation for wireless networks

A wireless communication system generates operating information indicating if a monitoring wireless communication device is in active mode or in idle mode for a wireless data service. The wireless system receives location information that indicates geographic locations of a monitored wireless communication device for delivery to the monitoring wireless communication device. The system stores the location information if the monitoring wireless communication device is in idle mode. The system wirelessly transfers the location information to the monitoring wireless communication device if the monitoring wireless communication device is in active mode. If the monitoring wireless communication device transitions from idle mode to active mode and has stored location information, the system generates summary location data for the monitored wireless communication device based on the stored location information and wirelessly transfers the summary location data to the monitoring wireless communication device.

Selective delivery of presence messages for wireless communication devices

An IP multimedia subsystem comprises a CSCF and an HSS. The CSCF is configured to receive a SIP registration message transferred by a user communication device and responsively transfer a registration request to the HSS. The HSS is configured to process the registration request to obtain IFC for the user communication device, wherein the IFC comprises processing instructions that direct the CSCF to perform an operation to dynamically obtain and load data into the IFC. The CSCF is configured to receive a SIP invite message transferred by the user communication device, process text from the SIP invite message against a set of keywords to determine a dynamic parameter based on a keyword match, process one of the processing instructions in the IFC to obtain and load the dynamic parameter into the IFC, process the IFC with the dynamic parameter to determine a communication session parameter, and transfer a SIP message with the communication session parameter responsive to the SIP invite message.

Dynamic determination of initial filter criteria

Methods for marking and verifying an authentication status of a wireless communication device are disclosed. When a wireless communication device is authenticated in a first wireless communication network, copies of a token, are stored in memory accessible by the wireless communication device and in memory accessible by a clearinghouse server. The clearinghouse server also stores a correlation between the token and the identity of the server that authenticated the wireless communication device. When the wireless communication device moves from the first network to a second network, the WCD transmits the token to a server in the second network, which can then query the clearinghouse server to determine the identity of the server that authenticated the WCD in the first network, confirm the authentication status of the wireless communication device, and allow the WCD to access a resource in or via the second network.

Tokenized authentication across wireless communication networks

Proxy mobile IP provides mobility to a mobile device that is not equipped to perform client mobile IP by moving the mobile IP signaling responsibility from the mobile device into the network. A network element performs the mobile IP signaling on behalf of the mobile device. In one scenario, the mobile device establishes a PPP session with a foreign agent, with no mobile IP signaling on top of the PPP session. The foreign agent then performs mobile IP signaling with the mobile device's home agent to negotiate a proxy mobile IP session for the device. Once the session registration lifetime has been established by the foreign agent and the home agent, the foreign agent communicates the registration lifetime to the mobile device by way of a PPP vendor-specific packet.
