Patent number: 11075742Abstract: A duplex frequency is supplemented by providing simplex frequencies and distributing a data load among them. A server initially communicates with a communications device using a duplex channel. A scheduler of the server determines when it is no longer optimal to use the single duplex channel, and distributes data among the duplex channel and the simplex channels. Before sending this data through multiple channels, the server first sends a schedule to the communications device to inform which bits of data are coming through which channels at which times. The scheduler compiles this schedule and sends it to the communications device through the duplex channel. A descheduler within the communications device receives the schedule and alerts the communications device to start receiving data on other simplex channels. The descheduler then puts the bits of data in order as they stream in across the duplex and simplex channels.Type: GrantFiled: July 3, 2019Date of Patent: July 27, 2021Assignee: AT&T MOBILITY II LLCInventors: Arthur Richard Brisebois, Yung Shirley Choi-Grogan, Melvin D.

Patent number: 10616859Abstract: Performing user equipment (UE) assisted indoor small cell location determination is presented herein. A method can include in response to sending, by an access point device, a request directed to a mobile device to obtain mobile device location data representing a user equipment location of the mobile device, receiving, by the access point device, the mobile device location data from the mobile device; and based on the mobile device location data, determining, by the access point device, access point location data representing an access point location of the access point device. In an example, the mobile device location data can include coordinates of the mobile device comprising latitude of the mobile device and longitude of the mobile device, and a time stamp representing a time of generation of the coordinates. In another example, the mobile device location data can include an altitude of the mobile device.Type: GrantFiled: November 21, 2018Date of Patent: April 7, 2020Assignee: AT&T MOBILITY II LLCInventors: Hongyan Lei, Yung Shirley Choi-Grogan, Cheng P.

Patent number: 9813774Abstract: A mobile broadcast service center and a mobile wireless network to deliver broadcast video to mobile wireless devices is described. When the mobile broadcast service center receives a request to deliver a broadcast video channel to a target mobile wireless device, it designates as target an intermediate node in the network that serves the target mobile wireless device. The mobile broadcast service center first determines if an existing channel bundle is routed to the target intermediate node. If this first determination is negative, the mobile broadcast service center routes a new channel bundle to the target intermediate node, including the requested broadcast video channel. If the first determination is positive, the mobile broadcast service center then determines if the requested broadcast video channel is in the existing channel bundle. If this second determination is negative, then it adds the requested broadcast video channel to the existing channel bundle.Type: GrantFiled: January 27, 2017Date of Patent: November 7, 2017Assignee: AT&T MOBILITY II LLCInventors: Jun Shen, Yung Shirley Choi-Grogan, Ming Zhang

Patent number: 9763145Abstract: Packet data protocol (PDP) contexts are managed upon cellular-to-femto handover, wherein femto network has disparate capabilities to support applications with distinct access point names (APNs) and quality of service (QoS) profiles. Based at least on activity factors of applications associated with PDP contexts, a QoS-based ranking of PDP contexts, and subscriber input, cellular network platform selects active PDP contexts to retain and suspend upon handover. A group of active PDP contexts is handed off in accordance with femto coverage capability, with remaining active PDP contexts suspended during handover. When a suspended PDP context, and application associated therewith, is resumed through femto coverage, a PDP context modification is conducted with a new APN and the application is routed to a corresponding femto gateway node and application server. Additionally, femto network platform performs a radio access bearer reconfiguration to meet QoS requirements of the resumed PDP context.Type: GrantFiled: November 7, 2016Date of Patent: September 12, 2017Assignee: AT&T MOBILITY II LLCInventor: Yung Shirley Choi-Grogan

Patent number: 9699693Abstract: An architecture is described that can provide enhancement with respect to circuit switched fall back. In particular, the architecture can reduce the signaling and delay of conventional systems that are necessitated by establishing a radio resource control connection prior to establishing the circuit switched fall back connection. For example, when user equipment is not in a radio resource control connected state at the time of a circuit switched fall back call, the radio resource control connection can be at least partially avoided by responding to a radio resource control connection request message with a radio resource control connection reject message that includes target cell reselection information.Type: GrantFiled: November 12, 2014Date of Patent: July 4, 2017Assignee: AT&T MOBILITY II LLCInventors: Weidong Hu, Inderpreet Singh Ahluwalia, Yung Shirley Choi-Grogan
