Abstract: Methods and computer-readable media are provided to dynamically update a home agent with location-based information for a mobile device such that a third party, such as a law enforcement agency, may access the information to determine a location associated with the mobile device and, therefore, with the user of the mobile device. A signaling message is sent to a packet-routing component. The signaling message contains location-based information for a communications session. A transaction update is sent from the packet-routing component to the home agent each time the location-based information is updated, such as when the mobile device enters a new coverage area. A binding table is populated with the updated information. An acknowledgment is then sent from the home agent to the packet-routing component indicating that the information has been updated in the binding table. The third party is now able to access the location-based information via the home agent.

Abstract: Computer systems, computer-readable media, and computerized methods for assigning network identifiers in a network are provided. A dynamic host configuration protocol (DHCP) server is employed to allocate various fractional IP addresses that include a common IPv4 address paired with a value of an IP version field within a data packet, wherein the value is selected from a plurality of available values. In order to differentiate between fractional IP addresses that share a common IPv4 address, a particular value of the IP version field is selected by the DHCP server and assigned to a client device when that particular value is not currently or previously assigned to another client device. Upon assignment to the client device, a fractional IP address that includes the common IPv4 address together with the particular value of the IP version field uniquely identifies the client device as a destination of a data packet within the network.

Abstract: A method, system, and device are provided for bootstrapping a Session Initiation Protocol Proxy for a mobile device when the Home Agent is bootstrapped for the device.

The Session Initiation Protocol Proxy address is sent to the mobile device along with the Home Agent address.

Abstract: A method to translate between Public Switched Telephone Network (PSTN) numbers and Voice over Internet Protocol (VoIP) addresses without performing an address translation database lookup. A network gateway receives and translates a first endpoint identifier associated with a destination client device to a second endpoint identifier associated with the destination client device. The first endpoint identifier is either a PSTN number or a VoIP address comprising at least the PSTN number and a predefined suffix and the second endpoint identifier is the other of the PSTN number and the VoIP address. The network gateway translates the first endpoint identifier to the second endpoint identifier without performing an address translation database lookup, by either adding the predefined suffix to or removing the predefined suffix from the first endpoint identifier.

Abstract: A method, system, and medium are provided for optimizing a stream of a media content through a wireless telecommunications network. A catalog receives a request from a mobile communication device for a particular media content. The catalog identifies that the media content is not available as reverse buffered media content. The request is then directed to a host of the media content where the host communicates the media to the mobile communications device. The media content is reverse buffered at a reverse buffer. The catalog updates to indicate that the media content is available as reverse buffered media content at the reverse buffer. The catalog receives a second request for the media content. The catalog determines that the media content is available and directs the request to the reverse buffer. The reverse buffered media content is communicated to the second mobile communication device.

Abstract: An Internet Protocol (IP) controlled modem receives a single modem command packet from a user IP system. The modem command packet indicates a destination IP address, a destination IP port number, and a modem command to initiate a voice call. The IP controlled modem determines if the destination IP address and the destination IP port number are authorized for modem control. If the destination IP address and the destination IP port number are authorized for modem control, then the IP controlled modem processes the modem command to wirelessly transfer call set-up signaling to a wireless communication network to initiate the voice call. The IP controlled modem receives a user data packet from the user IP system and wirelessly transfers the user data packet over the voice call.
