Patent number: 10972876Abstract: Methods, systems, and devices for wireless communications are described for providing local broadcasts for group calls. A user equipment (UE) may request a group call, and either a base station or a local server dedicated to the base station may determine whether to allow the group call based at least in part on an assessed level of interest for the group call. If the group call occurs, the UE may perform one or more aspects of user plane processing for the broadcast data—such as setting Internet protocol (IP) addresses in IP packets, encryption, compression, or media formatting—and may transmit the broadcast data to the base station. The base station may then transmit the broadcast data to one or more interested UEs via one or more multicast transmissions without routing the broadcast data through other network nodes, which may reduce latency and provide other benefits.Type: GrantFiled: January 30, 2018Date of Patent: April 6, 2021Assignee: Qualcomm IncorporatedInventors: Srinivasan Balasubramanian, Kuo-Chun Lee, Nagaraju Naik, Carlos Pazos

Patent number: 10498551Abstract: Methods, systems, and devices for wireless communication are described. Data for a broadcast or multicast service may be sent over a control channel. A network device may broadcast a message to indicate a plurality of enhanced multimedia broadcast multicast service (eMBMS) services offered by the network. The mobile device may transmit an indication to the network device identifying an eMBMS service of interest. The network device may transmit a configuration message before broadcasting or multicasting data of the eMBMS service of interest. The configuration message may notify the mobile device of a control channel on which to receive the data related to the eMBMS service. The network device may then broadcast or multicast the eMBMS service data on the control channel. The data may be segmented at a particular protocol layer and mapped to several transmission time intervals within each repetition of the control channel.Type: GrantFiled: September 5, 2017Date of Patent: December 3, 2019Assignee: QUALCOMM IncorporatedInventors: Kuo-Chun Lee, Sivaramakrishna Veerepalli, Liangchi Hsu, Chun-Hao Hsu, Suli Zhao, Ralph Akram Gholmieh, Nagaraju Naik, Carlos Pazos, Masato Kitazoe, Mungal Singh Dhanda, Hao Xu, Feilu Liu

Patent number: 10382950Abstract: Certain aspects of the present disclosure generally relate to wireless communications. In some aspects, a mobile device may receive configuration information, associated with configuring a state of the mobile device, via a unicast transmission, and may access a header-compressed broadcast transmission using the configuration information received via the unicast transmission. In some aspects, a network entity may transmit configuration information, to facilitate decompression of a header-compressed broadcast transmission, via a unicast transmission to a mobile device of a plurality of mobile devices, and may transmit the header-compressed broadcast transmission to the plurality of mobile devices in accordance with the configuration information.Type: GrantFiled: September 13, 2017Date of Patent: August 13, 2019Assignee: QUALCOMM IncorporatedInventors: Kuo-Chun Lee, Sivaramakrishna Veerepalli, Min Wang, Ralph Akram Gholmieh, Nagaraju Naik, Carlos Pazos, Alan Soloway, Haris Zisimopoulos, Xipeng Zhu

Publication number: 20140134970Abstract: An emergency notification service is described that is delivered using an evolved multimedia broadcast-multicast service (eMBMS). An emergency notification is sent out to user equipment (UE) in affected areas. In response to receiving the emergency notification, the UE searches the appropriate emergency multicast service acquisition information for multiple potential types of available emergency content that is provided by the eMBMS system in the network and tunes to the eMBMS to receive the emergency content. In selected aspects, the transmitted information, including the notifications and content may be scrambled using the same cell ID for each of the cells transmitting the same content. This improves the quality of the transmitted signals allowing for more reliable receipt and decoding by the receiving UEs.Type: ApplicationFiled: November 8, 2013Publication date: May 15, 2014Applicant: QUALCOMM IncorporatedInventors: Marcelo Dias Carlos Pazos, Xiaoxia Zhang, Chaitali Gupta, Jun Wang, Nagaraju Naik, Ralph A.

Publication number: 20070061860Abstract: Apparatus and method for providing and receiving media programming information including providing programming package information comprising attributes of a package of media presentation channels. Further, a subscription characteristic is defined that determines an ability subscribe to the package and to present the programming package information on a device. The device operates to compare the subscription characteristic with device-related subscription information. A subscription is allowed and/or the programming package information is presented on the device based on a predetermined relationship between the subscription characteristic and the device subscription information.Type: ApplicationFiled: November 8, 2005Publication date: March 15, 2007Inventors: Gordon Walker, An Chen, Bruce Collins, Joseph Barone, Mark Charlebois, Carlos Pazos

Publication number: 20050068896Abstract: A system and method for transmission control protocol (TCP) acceleration. Incoming acknowledgement (ACK) packets belonging to a TCP session are received, and an upstream queue is searched for queued acknowledgment packets belonging to the same TCP session. If the incoming acknowledgment packet is not a duplicate of the queued acknowledgment packet, one of the queued acknowledgment packets is replaced with the incoming acknowledgment packet in the position in the upstream queue occupied by the oldest of the queued acknowledgment packets. After the oldest queued acknowledgement packet is replaced, remaining acknowledgement packets in the queue are dropped.Type: ApplicationFiled: September 30, 2003Publication date: March 31, 2005Inventor: Carlos Pazos
