Patent number: 9848358Abstract: An apparatus is used to perform a Circuit Switched (CS) fallback in wireless communications. The Non-Access Stratum (NAS) of the apparatus determines whether to perform a CS fallback based on an Internet Protocol (IP) Multimedia Subsystem (IMS) registration status, and sends a service request indicating a request to perform the CS fallback when the WTRU is attached to a CS domain. The apparatus also includes an Access Stratum (AS) that receives the CS service request from the NAS, sends an indication of the CS service request in a Radio Resource Control (RRC) message to an Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN), wherein the RRC message includes CS service information, and receives a handover command in response to the CS service request.Type: GrantFiled: November 1, 2013Date of Patent: December 19, 2017Assignee: InterDigital Patent Holdings, Inc.Inventors: Shankar Somasundaram, Mohammed Sammour, Ulises Olvera-Hernandez, Rajat Mukherjee, Catherine Livet

Patent number: 9788252Abstract: Systems and methods are provided for routing internet protocol (IP) traffic flows when connected to a mobile network and a local network. A wireless transmit and receive unit (WTRU) determines whether to offload an IP traffic flow from the mobile network to the local network based on the destination address of the IP traffic flow. When the destination address is local, the WTRU routes the IP traffic flow through local network. The WTRU determines whether to offload IP traffic to the local network based on the stability state of the local network When the local network connection is sufficiently stable for the application associated with the IP traffic, the IP traffic is offloaded to the local network by selecting the local IP address as the source IP address.Type: GrantFiled: February 24, 2012Date of Patent: October 10, 2017Assignee: InterDigital Patent Holdings, Inc.Inventors: Michelle Perras, Alexander Reznik, Catherine Livet

Patent number: 9660911Abstract: The present invention relates to a method for confirming the delivery of a data packet in a mesh network by sending an acknowledgement (ACK) to an ingress mesh point (IMP). A mesh network comprises a plurality of mesh points that are wirelessly linked together. A data packet sent by a station (STA) is received by an IMP. A MAC frame is generated for transmission of the data packet and the frame is forwarded to an egress mesh point (EMP) in order to provide a service by the mesh network. The MAC frame includes a field comprising an IMP address and an EMP address. When the EMP, (or optionally an intermediate mesh point), receives a data packet successfully, the EMP or the intermediate mesh point sends an ACK to the IMP or preceding mesh point.Type: GrantFiled: March 30, 2015Date of Patent: May 23, 2017Assignee: InterDigital Technology CorporationInventors: Catherine Livet, Guang Lu, Juan Carlos Zuniga

Patent number: 9655007Abstract: Systems, methods, and instrumentalities are disclosed to communicate traffic flow information to a network. A user equipment (UE) may detect a traffic flow (e.g., using one or more of the traffic detection implementations described herein). A 5-tuple associated with the traffic flow may be unknown by the network. The UE may issue an alert to the network. The alert may indicate to the network that the traffic flow has been detected. The UE may determine the 5-tuple associated with the traffic flow. The UE may report the 5-tuple to the network. The report may be in response to one or more of: a request received from the network requesting traffic flow information; or, a determination that a first policy condition has been met.Type: GrantFiled: June 28, 2012Date of Patent: May 16, 2017Assignee: InterDigital Patent Holdings, Inc.Inventors: Alexander Reznik, Chonggang Wang, Catherine Livet, Kenneth F. Lynch, Robert G. Gazda, Kevin Di Lallo, Martin Jolicoeur, Jeremy Pallats, Michel Roy, Reeteshkumar Varshney

Publication number: 20160366610Abstract: A method and system for managing radio resources in a time-slotted wireless communication system is based on the quality of service (QoS) information of a user. A plurality of time slots of a radio resource are sorted into a plurality of different categories, such as high QoS time slots, high capacity time slots, and balanced time slots. Each category is associated with a different level of QoS. QoS information with respect to a user is obtained in response to a radio resource request received from the user. The user is associated with a particular category of time slots based on the QoS information of the user.Type: ApplicationFiled: August 23, 2016Publication date: December 15, 2016Inventors: Catherine Livet, Guang Lu, Shamin Akbar Rahman, Maged Zaki
