Patent number: 11825529Abstract: Disclosed herein are systems and methods for facilitating wireless communication of a wearable device. In one aspect, a wireless device receives a paging message from a cellular network, via a wireless link between the wireless device and a companion device. The paging message can be received while a cellular modem of the wireless device is operating in reduced power mode and not registered with the cellular network, and the companion device is registered with the cellular network. The wireless device can transition the cellular modem from the reduced power mode to an active mode in response to receiving the paging message via the wireless link with the companion device. The wireless device can register with the cellular network after the modem has transitioned to active mode, to establish a cellular link directly with the cellular network.Type: GrantFiled: July 9, 2021Date of Patent: November 21, 2023Assignee: Meta Platforms Technologies, LLCInventors: Srinivasa Prasad Vangaru, Qi Qu, Ping Wang, Dong Zheng, Insoo Hwang, Jiansong Wang, Gahima Stephen Mbonye, Swaminathan Balakrishnan

Publication number: 20230292313Abstract: Disclosed herein are systems and method for user equipment (UE) based supplemental uplink configuration. A UE can identify, according to a characteristic of the UE for wireless communication, a frequency band for communicating via a supplemental uplink. The UE can transmit, via a transceiver to a base station, a first message comprising an identification of the frequency band and a request to access the frequency band for communicating via the supplemental uplink. The UE can receive, via the transceiver from the base station responsive to the first message, a second message comprising a configuration for the supplemental uplink corresponding to the frequency band. The UE can communicate, via the transceiver, traffic via the supplemental uplink in the frequency band, according to the configuration.Type: ApplicationFiled: February 14, 2023Publication date: September 14, 2023Inventors: Achaleshwar Sahai, Ping Wang, Yee Sin Chan, Qi Qu, Kyungho Kim, Srinivasa Prasad Vangaru

Patent number: 10750415Abstract: A wireless network infrastructure, comprising static and roaming mobile nodes (including one or more types of access-points), avoids unnecessary handoffs and unstable RF regions, and enables at least selected context-aware-capable mobile nodes to provide context-aware services to connected clients. More particularly, each of at least selected static nodes is enabled to provide the context-aware-capable mobile nodes with context information regarding the static node's relative position and direction, details of information served by the static node, special flags indicative of relevant impending changes in the foregoing parameters, and a range of signal strength values defining a stable RF zone for associated mobile nodes. Each context-aware-capable mobile node accordingly creates a context map that at least in part enables determination of the mobile node's next change in static node association and the preferred timing for the change.Type: GrantFiled: August 13, 2018Date of Patent: August 18, 2020Assignee: Firetide, Inc.Inventors: Sudhir Hirudayaraj, Krishna Belathur Srinivasa Prasad

Patent number: 9578554Abstract: Certain aspects of the present disclosure relate to techniques for improving a circuit-switched fallback (CSFB) user experience. In aspects, methods and systems for autonomously returning a user equipment (UE) from a 2G (2nd generation)/3G (3rd generation) network to an LTE (Long Term Evolution) network are provided. The UE may store a flag to note whether a current circuit switched (CS) call in the 2G/3G network is a result of a CSFB. The UE, in response to detecting a termination of the current CS call in the 2G/3G network and determining that the terminated call was a CSFB call (e.g., from the status of the flag), may trigger a mobility mechanism to autonomously return the UE to the LTE network.Type: GrantFiled: September 14, 2012Date of Patent: February 21, 2017Assignee: QUALCOMM INCORPORATEDInventors: Bhupesh Manoharlal Umatt, Krishna Rao Mandadapu, Srinivasa Prasad Vangaru, Sathish Krishnamoorthy, Supratik Bhattacharjee, Joe Thomas, Thomas Klingenbrunn, Shyamal Ramachandran
