Patent number: 8718726Abstract: Methods and apparatus for reducing voice call drop rate. Existing devices do not account for the added burden of background services on voice calls. Specifically, multi-RAB scenarios (e.g., a voice call and background services) can experience significant reduction in call quality. Accordingly, in one exemplary embodiment, background services that are not time-critical and/or application-critical can be suspended while a voice call is in progress. By suspending background traffic during a call, the device can avoid unnecessary multi-RAB voice call operation, which significantly improves overall network operation and user experience.Type: GrantFiled: September 27, 2012Date of Patent: May 6, 2014Assignee: Apple Inc.Inventors: Umesh K. Shukla, Sachin J. Sane

Publication number: 20140065974Abstract: Conserving battery by a wireless user equipment (UE) device in substantially stationary conditions. A first wireless link may be established with a first cell. It may be determined that the UE device is substantially stationary. One or more signal strength and/or signal quality metrics associated with the first wireless link may be measured. The one or more signal strength and/or signal quality metrics may be below a first threshold. The UE may ordinarily be configured to perform a search for neighboring cells if the one or more signal strength and/or signal quality metrics are below the first threshold. The UE may not actually perform a search for neighboring cells, based on determining that the UE is substantially stationary.Type: ApplicationFiled: August 28, 2012Publication date: March 6, 2014Inventor: Sachin J.

Publication number: 20140066038Abstract: In order to improve the management of the power consumption of electronic devices (such as cellular telephones), the operating mode of an interface circuit in an electronic device may be changed when certain commands are received. In particular, when one or more commands are received that disable data communication via the interface circuit and a cellular-telephone network and/or enable communication via another interface circuit in the electronic device and a wireless local area network (WLAN), the interface circuit may be transitioned to an operating mode in which data communication via the cellular-telephone network using a communication protocol that supports only data and no voice is disabled. For example, the communication protocol may include a Long Term Evolution (LTE)-compatible communication protocol.Type: ApplicationFiled: November 21, 2012Publication date: March 6, 2014Applicant: APPLE INC.Inventors: Sachin J.

Patent number: 8346274Abstract: A method to control multiple radio access bearers is performed at a mobile wireless communication device when the mobile wireless communication device is connected to a radio network subsystem in a wireless communication network by first and second bidirectional radio access bearers. The mobile wireless communication device transmits a data packet on an uplink of the first bidirectional radio access bearer to the radio network subsystem. When the data packet is not correctly received by the radio network subsystem, the mobile wireless communication device retransmits the data packet repeatedly. After N retransmissions of the data packet, the mobile wireless communication device releases the first bidirectional radio access bearer while maintaining the second bidirectional radio access bearer. The first bidirectional radio access bearer provides a channel to transport packet switched data, and the second bidirectional radio access bearer provides a channel to transport circuit switched data.Type: GrantFiled: May 21, 2010Date of Patent: January 1, 2013Assignee: Apple Inc.Inventors: Sachin J.
