Patent number: 10897728Abstract: A network may implement a method to support a mobility of a wireless transmit/receive unit (WTRU). The network or network functions may identify the WTRU that is associated with one or more capabilities and one or more mobility properties. The network or network functions may determine subscription information and network policy information for the WTRU. The network or network functions may select a mobility pattern for the WTRU based on the one or more capabilities and the one or more mobility properties associated with the WTRU, the subscription information, and the network policy information. The mobility pattern may be associated with a mobility parameter and a value corresponding to the mobility parameter.Type: GrantFiled: January 13, 2017Date of Patent: January 19, 2021Assignee: IDAC Holdings, Inc.Inventors: Guanzhou Wang, Mahmoud Watfa, Saad Ahmad, Ulises Olvera-Hernandez

Publication number: 20200404734Abstract: Methods, systems, and apparatuses for protocol data unit (PDU) session management over different access technologies (ATs) are disclosed. A wireless transmit/receive unit (WTRU) may receive a first message from a network over a first access technology. The first message may include an indication for the WTRU to reestablish resources for one or more protocol data unit (PDU) sessions over a second access technology. The WTRU may determine that a PDU session of the one or more PDU sessions is locally deactivated by the WTRU. The WTRU may determine that it is in a limited service state associated with the second access technology. The WTRU may send a second message via the first access technology. The second message may include a PDU session status information element (IE) indicating the PDU session is locally deactivated such that the network releases the PDU session.Type: ApplicationFiled: January 8, 2019Publication date: December 24, 2020Applicant: IDAC HOLDINGS, INC.Inventors: Mahmoud Watfa, Behrouz Aghili, Saad Ahmad, Xiaoyan Shi, Ulises Olvera-Hernandez

Publication number: 20200404472Abstract: Systems, methods, and instrumentalities are disclosed for priority handling for ProSe Communications. A relay wireless transmit/receive unit (WTRU) may act as a relay between the network and the remote WTRU. The relay WTRU may receive a temporary mobile group identity (TMGI) request message from a remote WTRU. The TMGI request message may include a TMGI, a ProSe per packet priority level associated with the TMGI, etc. The relay WTRU may receive an evolved multimedia broadcast multicast service (eMBMS) data packet from a network. The eMBMS may be associated with the TMGI. The relay WTRU may apply the received ProSe per packet priority level associated with the TMGI to the received eMBMS data packet. The relay WTRU may relay the eMBMS data packet to the remote WTRU based on the ProSe per packet priority level. The relay WTRU may forward the eMBMS data packet to the remote WTRU via a PC5 interface.Type: ApplicationFiled: August 31, 2020Publication date: December 24, 2020Applicant: InterDigital Patent Holdings, Inc.Inventors: Mahmoud Watfa, Guanzhou Wang, Saad Ahmad, Amir Helmy, Ulises Olvera-Hernandez

Publication number: 20200396648Abstract: Certain aspects of the present disclosure provide techniques for handling slice information for a roaming user equipment (UE). In some cases, the UE may send, to a network entity, a request with an information element (IE) indicating one or more protocol data unit (PDU) sessions to be transferred from a source network to a target network. After receiving, from the network entity, a response with an IE identifying one or more of the PDU sessions allowed to be transferred to the target network and indicating slice information applicable in the target network for the one or more PDU sessions allowed to be transferred, the UE may update slice information for each of the PDU sessions allowed to be transferred based on the IE in the response.Type: ApplicationFiled: June 12, 2020Publication date: December 17, 2020Inventors: Mahmoud WATFA, Lenaig Genevieve CHAPONNIERE, Stefano FACCIN, Hong CHENG, Miguel GRIOT

Publication number: 20200389827Abstract: Methods and apparatuses for redirecting a wireless transmit/receive unit (WTRU) to a dedicated core network (CN) node are described. An apparatus is configured to initiate a Service Request with a non-dedicated network node. The apparatus is configured to receive a special identifier in response to the Service Request, which indicates the apparatus should be redirected to a dedicated CN node based on subscription information. Radio access network resources associated with the apparatus may be released and the apparatus may then perform a tracking area update (TAU) request which is then forwarded to the dedicated CN node.Type: ApplicationFiled: August 25, 2020Publication date: December 10, 2020Applicant: InterDigital Patent Holdings, Inc.Inventors: Mahmoud Watfa, Guanzhou Wang, Behrouz Aghili, Amir Helmy

Patent number: 10856221Abstract: A wireless transmit/receive unit (WTRU) is configured to receive at least three sets of parameters associated with power saving. A first set of the parameters is associated with an idle state. A second set of the parameters is associated with a connected state. A third set of the parameters is associated with not being in a connected state and remains registered with a network and maintains a packet data network (PDN) connection. The WTRU is configured to enter active times based on the third set of parameters on a condition that the WTRU is not in the connected state and remains registered with the network. During the active times, the WTRU is configured to monitor physical downlink control channels (PDCCHs) for paging messages.Type: GrantFiled: October 1, 2018Date of Patent: December 1, 2020Assignee: INTERDIGITAL PATENT HOLDINGS, INC.Inventors: Guanzhou Wang, Saad Ahmad, Behrouz Aghili, Martino M.

Publication number: 20200304409Abstract: A system and apparatus for addressing the different types of mobility of a wireless transmit/receive unit (WTRU) in a network. A radio access network (RAN) may send a request for configuration information to a gateway device including a device ID of a WTRU, a service ID, and a RAN address. Once the RAN receives configuration information from the gateway device including a forwarding table, the RAN may be prepared to receive non-IP data from a WTRU including a routing tag. The routing tag may be based on the device ID of a WTRU and service ID. The RAN may transmit the non-IP data received from the WTRU to the gateway device over a routing path based on the routing tag and a forwarding table where the non-IP data is forwarded on to its detention, such as another WTRU or an Application Server.Type: ApplicationFiled: March 30, 2017Publication date: September 24, 2020Applicant: IDAC HOLDINGS, INC.Inventors: Guanzhou Wang, Saad Ahmad, Mahmoud Watfa

Publication number: 20200178196Abstract: A WTRU may initiate access for a PDU session over multiple access networks. The WTRU may register with two or more access networks. For example, the WTRU may register with a 3GPP access network (e.g., LTE Advanced) and a non-3GPP access network (e.g., Wi-Fi). The WTRU may determine to request a multi-access PDU session for a (e.g., at least one) PDU session. A multi-access PDU session may correspond to a PDU session where the WTRU communicates one or more PDUs associated with the PDU session over the 3GPP access network and one or more PDUs associated with the PDU session over the non-3GPP access network. The WTRU may receive a confirmation message indicating that a multi-access PDU session has been established. The WTRU may send uplink data over the 3GPP access network and the non-3GPP access network, e.g., in accordance with the established multi-access PDU session.Type: ApplicationFiled: August 10, 2018Publication date: June 4, 2020Applicant: IDAC Holdings, Inc.Inventors: Guanzhou Wang, Saad Ahmad, Khalid Anwar, Behrouz Aghili, Ulises Olvera-Hernandez, Mahmoud Watfa
