Patent number: 9083355Abstract: Methods and apparatus for using end nodes, e.g., wireless terminals, to discover base stations and communicate information about discovered access nodes, e.g., base stations, to other access nodes in a system are described. As the wireless terminal roams in the system and new access nodes are encountered, one or more physically adjacent access nodes will be informed of the presence of the new access node as a result of communications with the wireless terminal. A message indicating an access node's inability to route a message to another access node which is known to a wireless terminal may trigger the wireless terminal to begin the process of updating access node routing and neighbor information.Type: GrantFiled: December 20, 2011Date of Patent: July 14, 2015Assignee: QUALCOMM IncorporatedInventors: Rajiv Laroia, Pablo Anigstein, David R. Mazik, Vladimir Parizhsky, Vincent Park, Murari Srinivasan, George Tsirtsis

Patent number: 8995397Abstract: Embodiments describe mobility management utilizing neighbor discovery and at least two pseudo wires. When a wireless device desires to handoff to a detected access router, such handoff may not be configured until such time as a current access router receives routing information of the target access router. In order to minimize handoff time, communication between the target access router and the wireless device can be through the current access router utilizing least two pseudo wires. Bidirectional neighbor discovery and create is conducted by the access routers allow subsequent wireless devices to automatically handoff between the access routers.Type: GrantFiled: February 21, 2013Date of Patent: March 31, 2015Assignee: QUALCOMM IncorporatedInventors: Richard John Dynarski, Hesham Soliman, Murari Srinivasan, David R.

Patent number: 8982835Abstract: The claimed subject matter relates to performing quality of service management in a mobile wireless communications system. In more detail, in some wireless environments a wireless terminal can be connected to multiple access nodes by way of links, and the wireless terminal can move between various access nodes changing its points of attachment to the network, including its primary point of attachment. Requesters of resources with respect to the wireless terminal can be notified when the primary point of attachment alters, such that subsequent requests are provided to a correct access node (e.g., base station).Type: GrantFiled: July 14, 2006Date of Patent: March 17, 2015Assignee: QUALCOMM IncorporatedInventors: Vincent D. Park, David R. Mazik

Patent number: 8886188Abstract: Systems and methods of decoupling session management from connection management of a wireless network by enabling transfer of a session between session controllers. A session transfer component transfers ownership of a session from a source session controller to a target session controller, wherein the session transfer does not necessarily require moving the associated connections therewith. Such transfer employs a Unicast Access Terminal Identifier (UATI) that is updated to inform the related base stations regarding transfer of the session.Type: GrantFiled: March 19, 2008Date of Patent: November 11, 2014Assignee: QUALCOMM IncorporatedInventors: Peerapol Tinnakornsrisuphap, David R. Mazik, Fatih Ulupinar, Parag Arun Agashe, Ravindra Patwardhan, Rajat Prakash

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: 8509799Abstract: The claimed subject matter relates to providing quality of service treatment to a subscriber (e.g., wireless terminal) based upon requests made on behalf of the subscriber by a plurality of logically separate entities from the subscriber. For instance, two network infrastructure devices, such as application servers, can initiate separate requests for quality of service treatment on behalf of the subscriber. Additionally or alternatively, a subscriber-side device can initiate a request for quality of service treatment on behalf of the subscriber. A provider of the quality of service treatment can provide appropriate treatment to one or more traffic flows based at least in part upon the requests.Type: GrantFiled: July 14, 2006Date of Patent: August 13, 2013Assignee: Qualcomm IncorporatedInventors: Vincent D. Park, David R. Mazik

Patent number: 8464272Abstract: A messaging entity within a messaging system may facilitate registration with the messaging system by software components. The messaging entity may facilitate unicast communication between registered software components. The messaging entity may facilitate registration for multicast events by software components. The messaging entity may facilitate multicast communication between registered software components.Type: GrantFiled: April 30, 2008Date of Patent: June 11, 2013Assignee: QUALCOMM IncorporatedInventors: Richard J. Dynarski, James Kelleman, David R. Mazik

Patent number: 8254364Abstract: A route protocol is established whereby a mobile device can communicate to a multitude of (receiving) base stations though a tunnel created through a serving base station. A message that includes a Route Creation Header can be transmitted by the mobile device to create the tunnel. The Route Creation Header is reviewed by the receiving base station while the mobile device is in a Waiting-To-Open State. Various errors might occur with respect to the Route Creation Header. These errors can be conveyed to the mobile device by base station by setting one or more error code fields. Once the errors are resolved, another attempt to create a tunnel with base station can be made, if desired.Type: GrantFiled: April 21, 2008Date of Patent: August 28, 2012Assignee: Qualcomm IncorporatedInventors: Rajat Prakash, Parag Arun Agashe, Fatih Ulupinar, David R.
