Abstract: Systems and methods for assigning unique network identifiers in a packet-switched wired network and methods for communicating with a network device in a packet-switched wired network are provided. A request for a unique network identifier for a network device is received. A socket-based unique network identifier, including an IP address and one or more ports, is assigned to the network 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.

Abstract: 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.

Abstract: 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.

The access node receives an authentication acknowledgment transferred from the authentication node in response to the request. In response to the acknowledgment, a billing identifier associated with the user session is generated at the access node. The billing identifier is transferred from the access node to an application node of the communication network.

Abstract: Media and systems are provided for limiting bandwidth consumption in a network environment by presenting customized browser-presentable resources. A request for a base universal resource locator (URL), followed by a request for a specific resource, is received. An optimized URL for the request is generated. When a predetermined number of requests for the specific component resource are received during the course of accessing the base URL, subsequent user requests for the base URL are redirected to the optimized URL. Thus, only the specific resources are presented for display. Requests to return to the base URL can result in discontinuing redirection. Returning to the base URL and accessing additional resources can modify the enhanced URL or redirect requests for the base URL to a difference component resource. Network bandwidth usage is enhanced by recognizing repetitive user requests.

Abstract: 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.

Abstract: Computer systems, computer-readable media, and computerized methods for resolving fractional IP addresses using domain name system (DNS)-enabled devices are provided. The system includes a local DNS server that accesses a correlation table, which maintains a mapping between fractional IP addresses and domain names. The fractional IP addresses each represent an IPv4 address paired with a respective value of an IP version field. The system also includes a client device that is capable of transmitting to the local DNS server a request message, which includes a destination name of a device targeted by the client device. Upon receiving the request message, the local DNS server compares the destination name against the correlation table. When a match is discovered within the domain names populated within the correlation table, the local DNS server identifies and transmits to the client device a fractional IP address mapped to the matching domain name.

Abstract: Methods and computer-readable media are provided to allow for the establishment of an Internet protocol (IP) data session with a dual-stack mobile communications device by authenticating the device. An IP data session is requested, and a home agent sends an indication of this request. A DNS server that will be assigned to a device is identified by querying a database and is identified based on the device's capabilities. The device capabilities are determined by a device-capability identifier that is associated with the user of the device or the device itself, such as a network access identifier. The capabilities may include the device type, applications, programs, or services that the user of the device is subscribed to, or capabilities that are inherent to the phone. Once the DNS server is identified, a server identifier is sent to the home agent, which assigns the DNS server to the device.
