Publication number: 20220337975Abstract: A MSIM UE may perform network operations for each network subscription. However, if the MSIM UE employs subscriptions for the same network, these operations may be performed redundantly. By notifying the network of multiple subscriptions at the UE and associating the multiple subscriptions at the network, the present invention provides power-saving at the UE and reduces network signaling overhead by optimizing communication for MSIM UE. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be configured to indicate to a network that the UE is associated with a plurality of network subscriptions, the plurality of network subscriptions including at least a first network subscription and a second network subscription, transmit location information using the first network subscription to the network, wherein the location information corresponds to a UE location, and receive data associated with the second subscription from the network.Type: ApplicationFiled: November 12, 2019Publication date: October 20, 2022Inventors: Parthasarathy KRISHNAMOORTHY, Tao LUO, Ozcan QZTURK, Ruiming ZHENG, Chetan CHAKRAVARTHY, Krishna Rao MANDADAPU, Vijay MARWAH, Ran BERLINER, Mueez AHMAD

Publication number: 20220295261Abstract: A MSIM UE may perform various network operations for each network subscription. However, if the MSIM UE employs subscriptions for different network operators, the UE may need to periodically tune away for an active data transmission. Such tune-away may cause the UE to miss scheduled communications from the network. Aspects of the present invention are directed to a mechanism by which a UE can notify a base station of the MSIM state, and thereby allow the network to improve scheduling for the UE to allow for periodic tune-away by the UE with minimal impact on scheduled communications. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may by a UE, such as MSIM UE. The apparatus may be configured to determine that the UE is associated with one or more network subscriptions, and transmit a subscription indication to a network device, wherein the subscription indication identifies a subscription state of the UE to the network.Type: ApplicationFiled: November 12, 2019Publication date: September 15, 2022Inventors: Parthasarathy KRISHNAMOORTHY, Ruiming ZHENG, Ozcan OZTURK, Chetan CHAKRAVARTHY, Krishna Rao MANDADAPU, Vijay MARWAH, Mueez AHMAD

Publication number: 20220295410Abstract: Methods, systems, and devices are described for enhanced power savings in wireless devices through mobile initiated dormancy procedure. A user equipment (UE) may establish radio resource control (RRC) connectivity with a base station of the network, and transmit and receive one or more distinct signaling messages for dormancy state initialization and suspension at the UE. Dormancy state implementation at the UE may conserve available power resources at the UE during periods of inactive data transaction. The one or more signaling messages may contain a single or multi-bit indication for the receiving device, and may be transmitted via direct signaling on upper layer protocols of the data network or mapped to allocated resources of a data transmission. The signaling messages may sustain synchronization between the interpreted functional mode of the UE at the base station and the implemented mode at the UE.Type: ApplicationFiled: May 27, 2022Publication date: September 15, 2022Inventors: Shravan Kumar Raghunathan, Srinivasan Balasubramanian, Parthasarathy Krishnamoorthy, Yonas Kidane, Chetan Chakravarthy, Kumarabhijeet Singh, Arvindhan Kumar, Krishna Rao Mandadapu

Patent number: 11006327Abstract: Methods, systems, and devices for wireless communications are described that provide for call continuity following radio link failure (RLF) through re-establishment of a voice call using a same or different radio access technology (RAT) before the call is dropped. Upon detection of RLF on a connection supporting a voice call, a UE may initiate a drop call timer and scan for available connections. The voice call may be attempted to be re-established if a connection is available on using a RAT of an existing connection. The voice call in such cases may continue without the call being dropped. Upon expiration of the drop call timer, the UE may attempt to establish a connection using a RAT identified during the duration of the drop call timer.Type: GrantFiled: September 27, 2018Date of Patent: May 11, 2021Assignee: QUALCOMM IncorporatedInventors: Shravan Kumar Raghunathan, Srinivasan Balasubramanian, Parthasarathy Krishnamoorthy, Chetan Chakravarthy, Yonas Kidane, Arvindhan Kumar, Kumarabhijeet Singh, Krishna Rao Mandadapu

Patent number: 10412014Abstract: The disclosure provides for a user equipment (UE) detecting an indication of an application-specific latency reduction triggering condition that may trigger switching of a communication state of the UE. For example, the UE may be in an initial state. The UE may transition into a different state that is associated with lower latency for data transfer. In an aspect, the UE may trigger the indication for latency reduction even when the network-configured criteria for the indication has not yet been met. The UE may trigger an application-specific latency reduction triggering condition during the startup of an application, which triggers a resource request message even before the network-configured threshold value for generating such resource request messages is satisfied. The resource request message may cause the network to command the UE to transition to a state that has a latency less than that in the current state.Type: GrantFiled: July 25, 2016Date of Patent: September 10, 2019Assignee: QUALCOMM IncorporatedInventors: Ravi Agarwal, Chetan Chakravarthy, Sharad Sambhwani, Sivaram Srivenkata Palakodety, Juha Mikko Sirkka
