Patent number: 9974116Abstract: A method and a wireless transmit/receive unit perform a handoff to a target base station having enhanced capabilities. A dual mode manager triggers a capabilities query for information regarding enhanced capability of the target base station, wherein the enhanced capability includes transmission in accordance with a high speed data mode. A generator sends the query to a server connected to the Internet via a first base station not having enhanced capability. The dual mode manager receives from the server via the first base station information regarding the enhanced capability. A handoff to the target base station is initiated by the dual mode manager on a condition that the received information indicates that the target base station has enhanced capability. The dual mode manager deactivates a first mode of operation for communication with the first base station and activates the high speed data mode for communication with the target base station.Type: GrantFiled: July 26, 2012Date of Patent: May 15, 2018Assignee: IPR LICENSING, INC.Inventors: Howard A. Heller, Kevin L. Farley, James A. Proctor, Jr.

Patent number: 8254307Abstract: An improved data communication network including a wireless link for accessing, from an end user machine, objects in a selected web page retrievable from an Internet server by means of suitable request messages is described. The wireless link includes a subscriber unit coupled to the end user machine and a base station coupled to the server. Web page data packets retrieved from the server with the use of the request messages are intercepted and locally stored in a gateway unit on the base station side of the wireless link. The gateway unit generates, from the retrieved web page data packets, additional request messages suitable for retrieving, from the server, object data packets corresponding to the objects on the selected web page. Such retrieved object data packets are also stored in the gateway unit.Type: GrantFiled: September 16, 2005Date of Patent: August 28, 2012Assignee: Tantivy Communications, Inc.Inventor: Howard A.

Patent number: 8238912Abstract: An improved arrangement is described for signaling enhanced capabilities of a wireless data communication system to a dual-mode wireless handset seeking access to such capabilities and normally operating in a first (non-enhanced) mode. The arrangement, which is especially advantageous for ascertaining operating mode capabilities of a new cellsite to which the handset is being handed off from an existing cellsite, includes a separate capabilities server that is associated with the system and contains a data base populated with information indicative of such capabilities. The handset generates a suitable query message which is transmitted to the data base in the first mode after the handoff to retrieve the capability information for the new cellsite location. The handset is switched from the first mode to the second (enhanced) mode for post-handoff operation if the retrieved capability information indicates that the new cellsite is capable of operation in the enhanced mode.Type: GrantFiled: May 31, 2001Date of Patent: August 7, 2012Assignee: IPR Licensing, Inc.Inventors: Howard A. Heller, Kevin L. Farley, James A. Proctor, Jr.

Publication number: 20070064654Abstract: A method and system are provided for transmitting information in a Mobile Internet Protocol (IP) environment, which includes a home network, a home agent (HA) provided at the home network, a base station (BS) broadcasting a pilot signal, a foreign agent (FA) provided at or associated with the BS, a mobile node (MN) providing the ability to detect and identify itself to a BS, a proxy mobile node (PMN) Identifying the MN wherein the PMN is provided at the BS. If the PMN identifies the MN, the PMN retrieves an IP address for each of the MN, FA and HA and sends a registration request to the FA. The FA relays the registration request to the HA, and the proxy MN is registered with the HA. The MN functionality is provided transparently to the MN by the PMN. The network may further include a further base station (BS) with a further foreign agent (FA) provided at or associated with the new BS. Another PMN is provided at the further BS.Type: ApplicationFiled: November 20, 2006Publication date: March 22, 2007Inventor: Howard Heller

Publication number: 20060120328Abstract: An improved method of maintaining data throughput during handoff in a wireless communication link operating with the Mobile IP protocol is described. A first base station initially servicing a mobile subscriber unit is associated with a first Mobile IP foreign agent that is registered with the Mobile IP home agent as a first mobility binding between the subscriber unit and the home agent. When the subscriber unit issues a request to be handed off from the first base station to a second base station, a second foreign agent associated with the second base station is registered with the home agent as a simultaneous binding with the first mobility binding between the subscriber unit and the home agent. This permits both foreign agents to simultaneously receive a sequence of data packets from the home agent. Before handoff is executed, the data packet sequence routed to the second foreign agent is stored at the second base station.Type: ApplicationFiled: November 14, 2005Publication date: June 8, 2006Inventors: Dale Wright, Howard Heller

Publication number: 20050249210Abstract: A method and system is provided for transmitting information from a mobile computer to a server utilizing point-to-point protocol (PPP). The system enables a PPP session to be maintained between a mobile user device and a PPP termination device. A Mobile IP address is assigned to customer premise equipment (CPE) associated with the user device, e.g., a PC. The CPE includes a Mobile IP Mobile Node and L2TP access concentrator (LAC). The Mobile IP address is registered with a Home Agent. The PC initiates a PPP session to the LAC, which initiates an L2TP session to an L2TP Network Server (LNS) via a tunnel between the Home Agent and a Foreign Agent. The Mobile IP Mobile Node registers with the Home Agent each time it detects a new base station. Thus, the Home Agent is informed of the new location to forward IP packets for the mobile computer.Type: ApplicationFiled: June 28, 2005Publication date: November 10, 2005Applicant: IPR LICENSING, INC.Inventor: Howard Heller

Publication number: 20050163073Abstract: Session services are employed in a networked computing environment to apply specific processing to an exchange of data between processes. In a wireless communication network, a single wireless link is typically shared among multiple users through wireless channels, which are allocated and switched among the users on a demand basis. Packets sent over the wireless link need to be signaled and tagged accordingly to initiate and employ the session service for the intended packets which comprise the flow. A method for identifying and applying session services to a wireless link includes identifying a packet flow over the wireless link corresponding to a received message by employing a flow identifier and filter. The packet flow corresponds to a session, and is mapped to at least one session service. The mapped session service is then applied to the received message.Type: ApplicationFiled: March 10, 2005Publication date: July 28, 2005Applicant: IPR LICENSING, INCInventors: Howard Heller, James Proctor

Publication number: 20030235206Abstract: A dual split-TCP connection for improving throughput in a data transmission system containing a wireless link is described. A pair of gateways are individually associated with a subscriber unit and a base station on opposite sides of the wireless link. The gateways respectively form spaced TCP proxy terminations for a pair of terminal machines, such as an end user machine and a server, between which data packets are exchanged over the system. Transmission over the wireless link itself employs an optimized wireless protocol or another non-TCP protocol such as UDP. Such elimination of the use of TCP over the wireless link minimizes delays attributable, e. g., to false readings of congestion on such link and the consequent unnecessary triggering of TCP congestion control/slow start mechanisms.Type: ApplicationFiled: May 7, 2001Publication date: December 25, 2003Applicant: TANTIVY COMMUNICATIONS, INC.Inventor: Howard A.
