  • Patent number: 10278122
    Abstract: A device and method are provided for concurrently using a plurality of radio access technologies (RATs) to support a wireless-enabled communications session. A set of data is processed at a client node to identify a subset of priority data. The set of data and the subset of priority data are respectively provided to a first and second protocol stack, which correspond to a first and second RAT. The first and second protocol stacks are then used to control the transmission of a first and second set of transmitted data, which in turn respectively comprise the set of data and the subset of priority data. The first and second sets of transmitted data are received by an access node, which uses corresponding first and second protocol stacks to control their reception. The first and second sets of transmitted data are then processed to generate a set of received data.

  • Patent number: 10212558
    Abstract: The present invention allows content to be delivered to a mobile terminal over different types of networks in order to efficiently use network resources. Content can be delivered using a select delivery method over a cellular network, a local wireless network, or a broadcast network. Within any of the networks, the content may be unicast to individual mobile terminals using individual content flows, multicast to a group of mobile terminals, or broadcast to any or all of the mobile terminals. Content can be multicast or broadcast to mobile terminals via different ones of the disparate networks. During a content flow, the network through which the content flow is delivered may be changed to allow the mobile terminal to receive the content through a different network. Further, the delivery method used to deliver the content may dynamically change as the number of mobile terminals receiving or requesting the content changes.

  • Patent number: 9521600
    Abstract: Systems, apparatuses, and methods for a handover procedure in heterogeneous networks are provided. In particular, an intermediate handover (IHO) is introduced. Certain aspects of the disclosure involve, a method, performed at a first base station of a wireless communications network. An indication that a user equipment (UE) is receiving coverage signal from a second base station can be received. A data packet destined for the UE can be transmitted to the second base station. A communications link with the UE can be maintained after transmitting the data packet to the second base station.

  • Patent number: 9503935
    Abstract: Systems, apparatuses, and methods for a handover procedure in heterogeneous networks are provided. In particular, an intermediate handover (IHO) is introduced. Certain aspects of the disclosure involve, a method, performed at a serving base station of a wireless communications network, where the serving base station serves a user equipment (UE). The method includes receiving a downlink (DL) signal quality indicator from the UE; and determining, from the signal quality indicator, whether a condition for an intermediate handover (IHO) state is satisfied. If the condition for the intermediate handover state is satisfied, the serving base station can initiate the intermediate handover state.

  • Patent number: 9497688
    Abstract: Methods, systems, and computer programs for managing mobile device applications are described. In some aspects, a mobile device application is prevented from accessing resources of a wireless network. For example, a wireless network operator system can determine that one or more mobile device applications are disapproved for use in the wireless network. In some implementations, the wireless network operator denies the disapproved mobile device applications access to the wireless network resources. In some implementations, mobile devices disable access to the wireless network by the disapproved mobile device applications.

  • Patent number: 9215656
    Abstract: A data transfer system may coordinate the transfer of user data and control data using a self-contained data channel without using a separate control channel in a time period between set-up and tear-down of the self-contained data channel. For example, a plurality of data transfer resources may be established in a self-contained data channel between user equipment and a network controller. User data is transferred between the user equipment and the network controller in at least one of the plurality of data transfer resources of the self-contained data channel. Additionally, control data is transferred between the user equipment and the network controller in at least one of the plurality of data transfer resources of the self-contained data channel.

  • Patent number: 9184958
    Abstract: Systems and methods are provided for encoding and transmitting codewords. A message is encoded in two encoders. For at least one of the two encoders, the message is algebraically modified prior to being encoded. In a specific example, the message is algebraically modified prior to being encoded in each of two traditionally non-systematic encoders, with the result that the output is equivalent to that of a turbo encoder.
