  • Publication number: 20170290036
    Abstract: Leveraging multiple network interfaces, such as Wi-Fi and cellular, on mobile devices can improve user experience for various applications. Deadline-aware MPTCP scheduling can complement existing MPTCP scheduler. The deadline-aware MPTCP scheduler can dynamically select transmission paths to minimize cellular usage while satisfying data transfer deadlines. The deadline-aware MPTCP scheduler can also address several challenges, such as determining the appropriate traffic pattern over cellular paths, designing proper APIs between MPTCP and applications, and making the scheduler functionality robust and lightweight.

  • Publication number: 20170281002
    Abstract: Methods, systems, and products measure health data related to a user. A time-stamped device identifier is received that uniquely identifies a communications device. A time-stamped sensor measurement is separately received. A difference in time between the time-stamped device identifier and the time-stamped sensor measurement is determined. When the difference in time is within a window of time, then the sensor measurement is associated with the device identifier.

  • Patent number: 9779752
    Abstract: A system for cloud acoustic enhancement is disclosed. In particular, the system may leverage metadata and cloud-computing network resources to mitigate the impact of noisy environments that may potentially interfere with user communications. In order to do so, the system may receive an audio stream including an audio signal associated with a user, and determine if the audio stream also includes an interference signal. The system may determine that the audio stream includes the interference signal if a portion of the audio stream correlates with metadata that identifies the interference signal. If the audio stream is determined to include the interference signal, the system may cancel the interference signal from the audio stream by utilizing the metadata and the cloud-computing network resources. Once the interference signal is cancelled, the system may transmit the audio stream including the audio signal associated with the user to an intended destination.

  • Publication number: 20170272898
    Abstract: A system that incorporates teachings of the present disclosure may include, for example, a coordinator device having a memory, and a controller. The memory can have computer instructions, which when executed by the controller, causes the controller to facilitate establishing a first virtual personal area network with a first sensor by executing computer instructions associated with a first application profile, and facilitate establishing a second virtual personal area network with a second sensor by executing computer instructions associated a second application profile. The first application profile can be defined by a first protocol specification, while the second application profile can be defined by a second protocol specification. The first protocol specification can also be operationally distinct from the second protocol specification. Other embodiments are disclosed.

  • Patent number: 9750050
    Abstract: Access priority for wireless devices located in an area in which radiofrequency (RF) coverage areas of a first wireless access point and a second wireless access point overlap is controlled by coordinating operation of the first wireless access point and the second wireless access point. The wireless devices access a common RF channel via a collision sense multiple access/collision avoidance mechanism. The probability of accessing the RF channel may be varied by adjusting the length of interframe spacings and the length of contention windows. The length of the interframe spacings and the length of the contention windows associated with the first access point and associated with the second access point are configured such that the probability of wireless devices associated with the first wireless access point accessing the RF channel is greater than the probability of wireless devices associated with the second wireless access point accessing the RF channel.

  • Publication number: 20170244767
    Abstract: A multimedia conferencing service uses accessible-forwarding-plane network elements such as OpenFlow® controllers and OpenFlow®-enabled switches. A conferencing server receives a conference subscription request including a network address of a L2/L3 signaling server, and connects to an accessible-forwarding-plane controller to control an accessible-forwarding-plane switch. Flow tables and group tables are managed to classify traffic with minimum table usage and update frequency. Media channels are established between clients through the OpenFlow®-enabled switches, relieving bottlenecks at the conferencing server.

  • Patent number: 9734542
    Abstract: Methods, systems, and products measure health data related to a user. Often times a weight scale, blood pressure monitor, or other medical measurement device is shared among a group of users. A time-stamped physiological measurement is compared to a time-stamped message from a mobile device. If the timestamps are contemporaneous, then the physiological measurement is bound to the mobile device.

  • Publication number: 20170201462
    Abstract: Data is routed in a mesh network of devices that can communicate wirelessly through a plurality of technologies. One or more of such devices receive broadcast message(s) from a destination device intended to receive the data, and generate a first radio link quality metric (RLQM) value based on the broadcast message(s). A source device originates and delivers a quantum of data with an embedded first RLQM value. A set of intermediate devices relays the quantum of data if a forwarding criterion is fulfilled; the forwarding criterion is based in part on the first RLQM value and a second RLQM value generated by an intermediate device in the set of intermediate devices based on the broadcast message(s). The intermediate device exploits an optical interface to transmit the quantum of data. The destination device broadcasts an acknowledgement signal in response to receiving intended data.

  • Publication number: 20170181211
    Abstract: In one example, a method and apparatus for web browsing on multihomed mobile devices having multiple communication interfaces are disclosed. In one example, the method establishes a primary multiple path transmission control protocol subflow for the transfer of a resource from a server to a user endpoint device. The method then determines a threshold of resource size. When the size of the resource is determined to exceed the threshold, the method establishes a secondary multipath transmission control protocol connection that cooperates with the primary multiple path transmission control protocol subflow for the transfer of the resource from the server to the user endpoint device.

  • Publication number: 20170086116
    Abstract: Improved non-cellular (e.g., Wi-Fi) link integration with a cellular (e.g., LTE) network is described. The improved link integration can relate to utilizing an eNodeB device (e.g., residing in a radio access network portion of a cellular network) as an anchor point rather than a packet data network gateway device (e.g., residing in a core network portion of the cellular network) utilized by other approaches. The improved link integration can maintain full compliance with or support for other approaches, and can reduce signaling overhead, simplify quality-of-service management, and/or provide a more rapid reaction to changes of access, particularly in cases where the eNodeB device and a non-cellular access point device are co-located.
