That is, the further CBS messages are received in a second DRX period determined through a self-learning process performed on the received CBS messages and the first DRX period. In this way, the power consumption of the terminal device for receiving the CBS messages can be reduced. As a result, the battery life of the terminal device can be guaranteed.Type: GrantFiled: August 30, 2016Date of Patent: April 4, 2023Assignee: Microsoft Technology Licensing, LLCInventors: Liyuan Liu, Jian Li

Patent number: 11622406Abstract: The present disclosure relates to dual connectivity methods. In one example method, a first access network device sends a request message to a second access network device, where the request message is used to request the second access network device to serve as a secondary access network device of a terminal served by the first access network device. Then, the first access network device receives an acknowledgment message from the second access network device, where the acknowledgment message is used to acknowledge to the first access network device that the second access network device agrees to serve as the secondary access network device of the terminal.Type: GrantFiled: June 28, 2019Date of Patent: April 4, 2023Assignee: Huawei Technologies Co., Ltd.Inventors: Xiaodong Yang, Wei Quan, Jian Zhang

Patent number: 11622303Abstract: This disclosure provides systems, methods and apparatus for determining a target base station timing advance value between a user equipment (UE) and target base station in connection with a random access channel (RACH)-less handover procedure. In one aspect, the UE may determine the target base station's timing advance based at least in part on a timing difference between the target base station and the source base station and based at least in part on a timing offset associated with an uplink and a downlink of the UE. In some aspects, the target base station may determine the timing advance using an uplink reference signal of the UE. In some aspects, the UE may report a timing difference between the target base station and the source base station, and the source cell may determine a timing advance based at least in part on the timing difference.Type: GrantFiled: July 26, 2021Date of Patent: April 4, 2023Assignee: QUALCOMM INCORPORATEDInventors: Hung Dinh Ly, Joseph Binamira Soriaga, Wanshi Chen, Peter Gaal, Tao Luo, Ozcan Ozturk, Karthika Paladugu

Patent number: 11617115Abstract: The present application discloses a method and eNB equipment for supporting seamless handover. The method comprises the following steps of: receiving, by a target eNB, random access information or an RRC connection reconfiguration completion message from a UE; transmitting, by the target eNB, a data transmission stopping indication message to a source eNB; and, stopping, by the source eNB, transmitting downlink data to the UE, and/or stopping, by the source eNB, receiving uplink data from the UE. The present invention further provides several other methods and eNB equipments for supporting seamless handover. By the methods for supporting seamless handover provided by the present invention, the delay of data transmission and the unnecessary data transmission or unnecessary data monitoring of a source eNB can be avoided, the waste of resources and the power consumption can be reduced, and the missing and duplication transmission of data can be avoided.Type: GrantFiled: September 29, 2021Date of Patent: March 28, 2023Assignee: Samsung Electronics Co., Ltd.Inventors: Lixiang Xu, Xiaowan Ke, Hong Wang, Gert Jan Van Lieshout

Patent number: 11611920Abstract: A system for delaying or inhibiting data is provided in order to shorten the time required for a reselection process from a first communication protocol to a second communication protocol. Reselection from the first communication protocol to the second communication protocol (e.g., 3G to 4G) requires a period of time without data transfers to allow the reselection to complete. The system delays or inhibits data transfers on the mobile device until the reselection process completes or the mobile device is idle for a predetermined length of time. In an embodiment, the system can buffer outgoing data and then send the data once the reselection has completed. In other embodiments, the system can drop packet sessions or ignore incoming packet pages. In another embodiment, the system can delay or inhibit data based on the priority of the data.Type: GrantFiled: April 22, 2022Date of Patent: March 21, 2023Assignee: AT&T MOBILITY II LLCInventor: Haywood Peitzer

Patent number: 11606746Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless communication device may identify a plurality of cells associated with serving a user equipment (UE), where each cell of the plurality of cells has been either selected for serving the UE or deselected for serving the UE. The first wireless communication device may transmit an indication of the plurality of cells associated with serving the UE to a second wireless communication device, where the indication includes information indicating whether each cell of the plurality of cells has been selected for serving the UE or has been deselected for serving the UE. Numerous other aspects are provided.Type: GrantFiled: November 2, 2020Date of Patent: March 14, 2023Assignee: QUALCOMM IncorporatedInventors: Qian Zhang, Yan Zhou, Tao Luo

Patent number: 11606733Abstract: A first base station (1) is configured to send, to a second base station (2), first configuration information that is necessary to establish a data bearer and a data radio bearer in the second base station (2) for a C/U-plane split scenario. Further, the first base station (1) is configured to send, to a third base station (3), configuration information (e.g., LPN information) regarding the data bearer established in the second base station (2) when a mobile station (4) moves from a first cell (10) to a third cell (30) (S103 and S104). It is thus, for example, possible to contribute to a reduction in wasted signaling when a UE moves between cells in the C/U-plane split scenario.Type: GrantFiled: January 10, 2020Date of Patent: March 14, 2023Assignee: NEC CORPORATIONInventors: Hiroaki Aminaka, Hisashi Futaki

Patent number: 11606732Abstract: The described technology provides a system and method for determining, inter alia, if a serving cell in a cellular network is an over-shooter cell serving calls outside an intended or designed coverage area by searching for eligible neighbor cells in a search area bounded by an azimuth of a sector antenna of the serving cell. The serving cell is determined to be an over-shooter cell when, e.g., the distance between the serving cell and mobile devices associated with the calls is larger than the average distance between the serving cell and one or more closest neighbor cells in a list of eligible neighbor cells identified in the search area.Type: GrantFiled: September 8, 2021Date of Patent: March 14, 2023Assignee: T-Mobile USA, Inc.Inventor: Nirmal Chandrasekaran
