Patent number: 8886180Abstract: Methods and apparatus for storing, manipulating, retrieving, and forwarding state, e.g., context and other information, used to support communications sessions with one or more end nodes, e.g., mobile devices, are described. Various features are directed to a mobile node controlling the transfer of state from a first access node to a second access node during a handoff operation thereby eliminating any need for state transfer messages to be transmitted between the second access node and the first access node during handoff. Other features of the invention are directed to the use of a core network node to store state information. State information stored in the core node can be accessed and used by access nodes in cases where a mobile node does not send a state transfer message during a handoff, e.g., because communication with the first access node is lost or because such messages are not supported.Type: GrantFiled: January 21, 2010Date of Patent: November 11, 2014Assignee: QUALCOMM IncorporatedInventors: Alan O'Neill, Matthew Scott Corson, Georgios Tsirtsis, Vincent D. Park, Richard J. Dynarski, David R Mazik, Leonid G. Sigal

Patent number: 8649264Abstract: Systems and methodologies are described that facilitate assigning a flow (e.g., IP flow) to a wireless network link from a bundle that includes a plurality of wireless network links. Assignments can be based upon characteristics associated with the flow and characteristics associated with the links. For example, a service class corresponding to the flow can be evaluated to determine flow related characteristics. Moreover, link related feedback can be analyzed to determine characteristics of the links.Type: GrantFiled: April 3, 2007Date of Patent: February 11, 2014Assignee: QUALCOMM IncorporatedInventors: Vladimir Parizhsky, Richard J.

Patent number: 7359326Abstract: In a Quality of Service system, segments in a TCP session are assigned a priority level. A segment may contain an acknowledgement and data. The system determines if network congestion is detected or anticipated in the segment's priority band or in a higher priority band. When the TCP segment arrives at a network point, the segment is split into an acknowledgement segment and a data segment. The acknowledgement segment is scheduled at a higher QoS priority than the data segment.Type: GrantFiled: February 5, 2003Date of Patent: April 15, 2008Assignee: 3Com CorporationInventors: Matthew Harper, Richard J.

Patent number: 6970443Abstract: A method is described of automatically locating and connecting a mobile wireless communications device to a packet-switched network such as the Internet. An Internet Protocol (IP) packet from a terminal on the network, destined for receipt by the mobile device, is received at a home agent acting as a gateway or router linking the packet switched network to a second network, such as LAN, coupled to a wireless communications network. The home agent transmits an access-request message to an authentication server. The access-request message includes a destination IP address associated with the mobile device found in the IP packet. The authentication server responsively issues an access-accept message to the home agent if the mobile device is authorized to receive the IP packet. The access-accept message comprises (a) information uniquely identifying said device, such as the IMSI/ESN number for the device, and (b) information identifying a network to use to locate said device.Type: GrantFiled: May 22, 2001Date of Patent: November 29, 2005Assignee: UTStarcom Inc.Inventors: Richard J.

Publication number: 20040174876Abstract: Multiple home agents for a home agent service provider network are implemented in a single computing platform in software as multiple virtual home agents. Each home agent is assigned or dedicated to a single virtual private network. Any number of home agents can be realized in the computing platform by multiple instantiations of a home agent program or code, and by providing unique IP addresses for each instantiation. Each home agent runs independently, and is independently configured and managed by the subscriber of the virtual private network service, freeing the service provider of having to manage and supervise low level processing tasks and customization features that the subscribers may want. In a representative embodiment, the computing platform comprises a router having a general purpose-computing platform.Type: ApplicationFiled: March 18, 2004Publication date: September 9, 2004Applicants: UTStarcom, Incorporated, 3Com CorporationInventors: Kenneth L.

Patent number: 6757276Abstract: Tones that are generated by a telephone or PC (such as DTMF tones) and subject to loss or noise during generation or during transmission along a medium are detected and replaced with substantially noise-free and distortionless digital signals. In one embodiment, the replacement of the tones is done in a modem embodied in an Internet telephony Gateway/Terminal, such as in a network access server coupling a time division multiplexed telephone line to a packet-switched network. The replacement of the tones may also be performed in any suitable device that provides an interface between a time division multiplexed transmission medium and a packet switched data network, such as in the modems of a cellular telephone network to Internet network access server.Type: GrantFiled: November 24, 1998Date of Patent: June 29, 2004Assignee: 3Com CorporationInventors: Matthew Harper, Richard J.

Patent number: 6628671Abstract: A network access server providing remote access to an IP network for a remote client initiates a PPP connection for a remote client quickly, and without requiring re-negotiation of Link Control Protocols and Network Control Protocols. The network access server has a PPP session with the remote client go dormant, for example when the user is a wireless user and goes out of range of a radio tower and associated base station. The network access server does not get rid of the PPP state for the dormant session, but rather switches that PPP state to a new session, such as when the client moves into range of a different radio tower and associated base station and initiates a new active session on the interface to the wireless network. The switching of PPP states may be within a single network access server, or from one network access server to another.Type: GrantFiled: January 19, 1999Date of Patent: September 30, 2003Assignee: VTStarcom, Inc.Inventors: Richard J.

Patent number: 6466571Abstract: A method of finding a mobile wireless communications device when an Internet Protocol (IP) packet from a remote user is sent to the device over an IP network. The mobile device does not have to register with the IP network in order to receive the IP. The method comprises the steps of receiving the IP packet at a home agent associated with a wireless communications network. The IP packet includes an IP address assigned to the device. If there is no current mobility binding record for the mobile device, instead of dropping the packet the home agent sends an access-request packet, containing the IP address, to an authentication server. The authentication server, e.g., a RADIUS server, maintains a table mapping the IP address for the device to an identification number uniquely associated with the device, such as the device's International Mobile Subscriber Identity number.Type: GrantFiled: January 19, 1999Date of Patent: October 15, 2002Assignee: 3Com CorporationInventors: Richard J.
