Publication number: 20180206161Abstract: Mobile service anchor management (MSAM) is facilitated. MSAM is an anchor management function/system for radio frequency (RF) access configuration/reconfiguration over the downlink, and uplink separated novel frequency division duplex systems. One method comprises determining, by a MSAM system comprising a processor, that a mobile device communicatively coupled to a first network device is associated with a region in which the first network device fails to have line of sight communication with the mobile device; and assigning, by the mobile service anchor management system, the mobile device to a second network device determined to have the line of sight communication for the region. Millimeter watt (mmW) BS devices and devices that operate on other RF bands can be utilized.Type: ApplicationFiled: March 12, 2018Publication date: July 19, 2018Inventors: Yuang Lou, Douglas A. Duet

Publication number: 20180160341Abstract: Internet protocol session continuity can be achieved via an access point registration process. Mobile devices near an access point device that has registered with a base station device can offload wireless communication from the base station device to the access point device. The access point device can be a known access point device that can be secured and subject to session continuity policies of a service provider. The session continuity policies can be stored at a content handover processor, which can oversee the handover processes between the base station device and the mobile device.Type: ApplicationFiled: January 16, 2018Publication date: June 7, 2018Inventors: Yuang Lou, Douglas A.

Patent number: 9918139Abstract: A system for providing a distributed architecture for mobile streaming content delivery is disclosed. In particular, the system may include bypassing a master head end facility and its accompanying fiber distribution network to deliver a content stream directly to mobile cell sites. In order to do so, the system may receive, at a cell cite, a content stream directly from a content satellite and then format the content into a format suitable for delivery to a subscriber device. The system may receive, such as via a radio access network, a request from the subscriber device to access the content stream. In response to the request from the subscriber device, the system may deliver the formatted content stream to the subscriber device. The distributed architecture may also allow for delivering the content stream jointly with voice data services, such as those provided in a Long-Term Evolution network or other network.Type: GrantFiled: July 7, 2015Date of Patent: March 13, 2018Assignee: AT&T Intellectual Property I, L.P.Inventors: Douglas A.

Publication number: 20180041856Abstract: Aspects of the subject disclosure may include, for example, a method including receiving, by a processing system, data from a plurality of machine-to-machine (M2M) communication devices, and aggregating the data to generate local information. The method can also include receiving and analyzing a message, from a user communication device, that includes a request regarding an M2M communication device. If the request cannot be responded to based on the local information, a query is transmitted to the M2M communication device based on the analyzing, and a reply to the query is received from the M2M communication device. The processing system receives the data and transmits the query message within the premises using millimeter-wave communications or WiFi communications. Other embodiments are disclosed.Type: ApplicationFiled: August 8, 2016Publication date: February 8, 2018Inventors: Yuang LOU, Douglas A. DUET

Publication number: 20170026951Abstract: Harmonization of wireless communication service delivery is facilitated. One method comprises receiving, by an anchor node, from a mobile device communicatively coupled to a network, first information indicative of a request for service for the mobile device, wherein the network comprises a first base station (BS) device configured to provide downlink communication between the first BS device and the mobile device, and another BS device configured for uplink communication between the mobile device and the other BS device. The first BS device can be a millimeter wave (mmW) BS device in some embodiments. The method also comprises generating information indicative of a transmission parameter for a type of access to the network device. The transmission parameter can be generated based on various criteria including, but not limited to, whether there is line-of-sight between the first device and the mobile device, the requested service and/or the availability of network resources.Type: ApplicationFiled: July 20, 2015Publication date: January 26, 2017Inventors: Yuang Lou, Douglas A.

Patent number: 8229506Abstract: An array antenna is utilized to enhance the adaptive acquisition capability of a communication connection with one or more wireless subscribers. Subscribers who are located outside the omnidirectional range of the array antenna are acquired by using adaptive beamforming techniques to create an acquisition beam dedicated to acquiring new connections with wireless subscribers. The acquisition beam may sweep through the coverage of the array antenna seeking subscribers who lie beyond the omni range of the array antenna, but fall within the acquisition range using adaptive beamforming.Type: GrantFiled: January 4, 2007Date of Patent: July 24, 2012Assignee: AT&T Intellectual Property I, L.P.Inventors: Douglas Duet, Yuang Lou

Patent number: 8149802Abstract: A fixed broadband wireless data access service providing shared wide-band packet-switched data transport for high speed data access in areas where conventional ADSL service and fiber optic service are unavailable. The wireless data access service is a point-to-multipoint cellular-type network that connects customers to data service providers through the ATM backbone of an existing network. Customers connect to the ATM backbone and data service provider through a cellular grid in which a wireless base station in each cell communicates with the individual customer wireless equipment within its cell site coverage area. The base stations are connected to an ATM backbone switch through wireless and wireline backhaul links. The upstream and downstream bandwidths of the wireless broadband network are engineered in various symmetric and asymmetric configurations to provide a shared packet-switched connection that emulates an uninterrupted, direct wireline ADSL connection.Type: GrantFiled: November 5, 2007Date of Patent: April 3, 2012Assignee: AT&T Intellectual Property I, LPInventors: Yuang Lou, Douglas Duet, Vijay Perumbeti, David Payne
