Patent number: 10595214Abstract: Methods, systems, apparatuses, and devices are described for managing wireless communication at a user equipment (UE). An exemplary method includes adding an identifier of a cell to a sub-optimal cell list based at least in part on a cell classification determination made by the UE, and avoiding a cell access procedure for the cell based at least in part on inclusion of the identifier in the sub-optimal cell list. Another exemplary method includes maintaining a sub-optimal cell list and an associated priority service exception list, initiating a service on the priority service exception list, identifying inclusion of a cell on the sub-optimal cell list, where the cell is associated with a cell access procedure initiated for the service, and accessing the cell included in the sub-optimal cell list based at least in part on inclusion of the service in the priority service exception list.Type: GrantFiled: July 15, 2016Date of Patent: March 17, 2020Assignee: QUALCOMM IncorporatedInventors: Arvind Santhanam, Francesco Grilli, Simon Walke, Venkata Potnuru, Vikas Gulati, Neha Goel

Publication number: 20170215116Abstract: Disclosed are methods and apparatus to prevent poor quality handoff decisions in mobile networks. The methods and apparatus effectuate a determination whether a predetermined condition concerning a cell has occurred as detected in the mobile device, such as unsuccessful handoff or a signal to noise ratio being less than a certain amount. Based on such determinations, poor quality handoff decisions can be realized by modifying or configuring the measurement report message to be sent to the serving network where the measurement report is configured to omit information concerning those cells not meeting the predetermined condition. Accordingly, these cells will not be considered in handoff decisions, thus increasing the quality of such decisions.Type: ApplicationFiled: January 25, 2016Publication date: July 27, 2017Inventors: Pavan Siravuru, Simon Walke, Manmohan Rawat, Awnit Kumar, Mungal Singh Dhanda, Naresh Babu Vungarala, Ravi Kanth Kotreka

Publication number: 20170041976Abstract: In a multi-subscription wireless communication device with a shared radio frequency (RF) resource supports an active data communication on a first network of a first SIM by performing tune-aways to support a subscription on a second SIM. After a tune-away of the shared RF to the second network, the wireless communication device may identify scheduled packet downlink acknowledgment/non-acknowledgment (ACK/NACK) message transmissions on the modem stack associated with the first SIM. The wireless communication device may determine whether a next scheduled packet downlink ACK/NACK (PDAN) message transmission to the first network is missed, and if so, increment a PDAN failure counter on the modem stack associated with the first SIM. If the value of the PDAN failure counter on the modem stack associated with the first SIM is equal to a preset threshold, the wireless communication device may force the shared RF resource to tune back to the first network.Type: ApplicationFiled: August 7, 2015Publication date: February 9, 2017Inventors: Hieu Trung Van, Abeezar Burhan, Simon Walke, Raghav Agarwal

Patent number: 9037168Abstract: The various embodiments include methods for managing how a MSMS communication device that is accessing an arbitrary combination of multiple telephony networks processes paging collisions. The embodiment methods promote improving a subscription's page blocking rate by causing a MSMS communication device to implement a retransmission remedial action for a blocked subscription. In the various embodiments, the MSMS communication device may implement the retransmission remedial action by increasing a blocked subscription's priority during a subsequent retransmission interval to increase the likelihood that the blocked subscription will receive a repeated page message from its mobile network during this retransmission interval. In some embodiments, the blocked subscription's current priority may be based on the number of retransmission intervals that are presently occurring.Type: GrantFiled: July 30, 2013Date of Patent: May 19, 2015Assignee: QUALCOMM IncorporatedInventors: Chih-Ping Hsu, Simon Walke, Shawn C. Morrison, Francis M. Ngai

Patent number: 9025576Abstract: Apparatus and methods are disclosed to provide for a multi-SIM wireless user equipment configured for block-level, or slot-level tune-away operations enabling simultaneous communication with a plurality of channels. The first and second channels may correspond to different RANs, each of which the user equipment may subscribe to as corresponding to information in a plurality of SIMs at the user equipment. In other examples, the first and second channels may correspond to different cells within a single RAN. In either case, the tune-away operations disclosed provide for reduced data loss at the first channel and in some examples improved communication performance at the second channel. Other aspects, embodiments, and features are also claimed and described.Type: GrantFiled: January 11, 2013Date of Patent: May 5, 2015Assignee: QUALCOMM IncorporatedInventors: Divaydeep Sikri, Mungal Singh Dhanda, Nigel Phillip Robinson, Simon Walke, Abeezar A.

Patent number: 9026125Abstract: Methods are provided that enable mitigation of desense from a transmission on a first radio frequency (RF) resource associated with a first SIM to a receiver circuit of a second RF resource associated with a second SIM in the same device. A multi-SIM wireless device, such as a dual-SIM dual active (DSDA) device, may utilize characteristics of uplink and downlink signals to determine an optimal action that reduces interference from conflicting signals. Mitigating actions do not require involvement on the network side, and may greatly improve processing time for implementing interference prevention measures.Type: GrantFiled: January 16, 2013Date of Patent: May 5, 2015Assignee: QUALCOMM IncorporatedInventors: Mungal Dhanda, Divaydeep Sikri, William Stancer, Simon Walke
