Patent number: 10278122Abstract: 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.Type: GrantFiled: August 6, 2018Date of Patent: April 30, 2019Assignee: BlackBerry LimitedInventors: Shalini Suresh Periyalwar, Mark E. Pecen, David Gwyn Steer

Patent number: 10278222Abstract: Devices and methods are provided for determining the proximity of client nodes within a wireless-enabled communication environment. A first client node comprises a database containing identification data associated with a plurality of wireless network access nodes and fingerprint data associated with the client node and a plurality of second client nodes. As the fingerprint information is updated, it is processed by the first client node to identify second client nodes that have matching, or similar, fingerprint information. Those that do are determined to be within a viable device-to-device (D2D) communication range.Type: GrantFiled: April 24, 2017Date of Patent: April 30, 2019Assignee: BlackBerry LimitedInventors: David Gwyn Steer, Dongsheng Yu, Robert Novak

Patent number: 9854462Abstract: A method of establishing communication links during a failure within a mobile communications network includes detecting disruptions in communications between a plurality of base stations and a plurality of mobile terminals. Survivability components are activated within the base station and the mobile terminal to operate in a survivability mode. The survivability mode enables communications and services to be provided by the surviving base stations to mobile terminals through activated survivability components. The alternate communication links may operate for as long as a disruption exists.Type: GrantFiled: June 17, 2015Date of Patent: December 26, 2017Assignee: BlackBerry LimitedInventors: David Gwyn Steer, Robert Novak

Patent number: 9468032Abstract: Devices and methods are provided for managing device-to-device (D2D) communications session in a wireless-enabled communication environment. A first client node comprises a database containing location and ID information associated with a plurality of second client nodes. The location information in the database is updated as individual second client nodes change their location. As the location information is updated, it is processed by the first client node to determine the distance between it and an individual second client node. If the distance between the first client node and the individual second client node is within a viable D2D communications range, then the user of the first client node is notified that a D2D communications session can be initiated with the individual second client node.Type: GrantFiled: January 11, 2016Date of Patent: October 11, 2016Assignee: BlackBerry LimitedInventors: Robert Novak, David Gwyn Steer, Dongsheng Yu

Patent number: 6032033Abstract: A selection diversity system and method for use in a TDMA (time division multiple access) radio system, particularly suited for DECT (Digital Enhanced Cordless Telephone) or PWT (personal wireless telephony) applications. A digitized version of a received signal is buffered long enough to allow selection diversity measurements to occur without corrupting the demodulation of the desired signal. While the received signal is being buffered, a single receiver makes a performance measurement on each of two antennas in sequence during the beginning of a received data burst, the beginning of the burst being determined by a timing signal fed back from a previous burst. The previously unused antenna is measured first to minimize the likelihood of having to perform two antenna switches. Also while the received signal is buffered, timing recovery and frequency offset correction are performed.Type: GrantFiled: December 3, 1996Date of Patent: February 29, 2000Assignee: Nortel Networks CorporationInventors: Bradley John Morris, David Gwyn Steer
