  • Patent number: 9848358
    Abstract: 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.

  • Patent number: 9788252
    Abstract: 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.

  • Patent number: 9660911
    Abstract: 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.

  • Patent number: 9655007
    Abstract: 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.

  • Publication number: 20160366610
    Abstract: 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.

  • Patent number: 9473986
    Abstract: Methods, systems and apparatus for managing and/or enforcing one or more policies for managing internet protocol (“IP”) traffic among multiple accesses of a network in accordance with a policy for managing bandwidth among the multiple accesses are disclosed. Among the methods, systems and apparatus is a method that may include obtaining performance metrics associated with the multiple accesses. The method may also include adapting one or more rules of one or more the policies for managing IP traffic among the plurality of accesses based, at least in part, on the performance metrics and the policy for managing bandwidth among the plurality of accesses. The method may further include managing IP traffic associated with at least one wireless transmit and/or receive unit (“WTRU”) among the plurality of accesses responsive to the adapted rules.
