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.

Patent number: 10212558Abstract: 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.Type: GrantFiled: May 29, 2015Date of Patent: February 19, 2019Assignee: BlackBerry LimitedInventors: Shalini Suresh Periyalwar, William Anthony Gage

Patent number: 9521600Abstract: 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.Type: GrantFiled: January 28, 2013Date of Patent: December 13, 2016Assignee: BlackBerry LimitedInventors: Chandra Sekhar Bontu, Yi Song, Zhijun Cai, Shalini Suresh Periyalwar

Patent number: 9503935Abstract: 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.Type: GrantFiled: January 28, 2013Date of Patent: November 22, 2016Assignee: BlackBerry LimitedInventors: Chandra Sekhar Bontu, Yi Song, Zhijun Cai, Shalini Suresh Periyalwar

Patent number: 9497688Abstract: 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.Type: GrantFiled: September 23, 2011Date of Patent: November 15, 2016Assignees: Certicom Corp., BlackBerry LimitedInventors: Mark Pecen, Niels Peter Skov Andersen, Shalini Suresh Periyalwar, Matthew Campagna
