Patent number: 9787806Abstract: A system may distribute radio networking traffic from a base station to one or more radio units in a bi-directional link. The system may transport the radio networking traffic over a digital network. The system may include a front-haul unit coupled to the radio units and in communication with the base station. The front-haul unit may encapsulate access signals from the base station within digital transport streams for transport over the digital network. The front-haul unit may multicast digital transport transmission streams to multiple radio units in a virtual cell. The digital transport streams may contain combined received access signals from multiple service providers in a neutral-host configuration. The radio units may map encapsulate incoming radio signals for return transport to the front-haul unit and then on the base station. The front-haul unit may transport data over the network to support wireless local area network service at the radio units.Type: GrantFiled: December 14, 2015Date of Patent: October 10, 2017Assignee: Avago Technologies General IP (Singapore) Pte. Ltd.Inventors: Amit Oren, Lowell D. Lamb, Fredrik Karl Olsson

Patent number: 9749050Abstract: A system for providing a reduced common public radio interface (CPRI) framelet link includes one or more cellular towers, each cellular tower including one or more cellular antennas and coupled to a first short CPRI fiber link. An access subsystem is coupled to a baseband pool. The access subsystem is coupled to the first short CPRI fiber link via a first framelet block, and the first framelet block facilitates interfacing the first short CPRI fiber link to the access subsystem.Type: GrantFiled: February 17, 2015Date of Patent: August 29, 2017Assignee: Avago Technologies General IP (Singapore) Pte. Ltd.Inventors: Lowell D. Lamb, Amit Oren, Timothy Andrew Ryan

Patent number: 9634857Abstract: A remote device management, diagnostics, and self-installation architecture employs multiple wireless links, which may include a local wireless link and a remote wireless link. The architecture employs cellular channels for remote management of customer premises equipment (CPE). Within the architecture, test devices may operate on the CPE. As examples, the test devices may include a cellular radio, or the test devices may be in communication with another device that includes the cellular radio.Type: GrantFiled: November 14, 2014Date of Patent: April 25, 2017Assignee: Avago Technologies General IP (Singapore) Pte. Ltd.Inventors: Lowell D. Lamb, Glen Kramer, Pierre Couillaud, John Kevin Markey, John Stuart Walley

Patent number: 9432120Abstract: Embodiments provide systems and methods for a probabilistic reporting mode, where an Optical Network Unit (ONU) sends a REPORT message only when it has data to transmit. The absence of a REPORT message from an ONU is treated by the Optical Line Terminal (OLT) as indicating absence of data to transmit at the ONU. In another aspect, embodiments include systems and methods for an unsolicited burst mode, where an ONU can be configured to transmit data in the upstream in an unsolicited manner. The unsolicited burst mode includes mechanisms to ensure that no data is lost due to potential collisions between ONUs.Type: GrantFiled: May 29, 2014Date of Patent: August 30, 2016Assignee: Broadcom CorporationInventors: Glen Kramer, Lowell D. Lamb

Patent number: 9379882Abstract: Systems and methods are provided to use of out-of-band (OOB) channels for the transport of network-synchronization signals and network control information. These OOB channels transport synchronization and control channels over low-frequency bands outside of the frequency bands used for the data channels. Locating expensive network-synchronization functions in the optical network unit (ONU) and sharing the derived synchronization signals among multiple downstream customer premises equipment (CPE) devices results in cost savings and provides a means for maintaining a continuous, end-to-end synchronization reference, even during periods when the data channels on the copper network segment are in an energy-efficiency mode (e.g., a low-power and/or sleep mode).Type: GrantFiled: May 2, 2014Date of Patent: June 28, 2016Assignee: Broadcom CorporationInventors: Lowell D. Lamb, Glen Kramer, Amit Oren

Patent number: 9356699Abstract: A dynamic readjustment of an energy efficient network control policy parameters in an optical network unit based on a Service Interoperability in Ethernet Passive Optical Network (SIEPON) protocol. The access link between the OLT and ONU has distinct properties that can be used to enhance the energy efficiency control policy on the network facing side of the ONU. In one embodiment, an adjustment mechanism can be based on the receipt, by an optical interface in an ONU, of a control command from an upstream OLT, wherein the control command is configured to provide a limitation on an available time period during which the ONU can communicate with the OLT over an optical fiber cable.Type: GrantFiled: November 8, 2012Date of Patent: May 31, 2016Assignee: BROADCOM CORPORATIONInventors: Wael William Diab, Ryan Hirth, Lowell D.

Patent number: 9351057Abstract: A service provisioning enabled management in Service Interoperability in Ethernet Passive Optical Network (SIEPON) switching subsystem. The delivery of network services to each of a plurality of subscribers coupled to an optical network unit (ONU) can be defined individually by the service provider. The service-specific functions within the ONU can be configured based on knowledge of the levels of provisioning of network services.Type: GrantFiled: November 24, 2012Date of Patent: May 24, 2016Assignee: BROADCOM CORPORATIONInventors: Wael William Diab, Ryan Hirth, Lowell D.

Patent number: 9264523Abstract: A remote management system employs multiple wireless links, which may include a local wireless link and a remote wireless link. The remote wireless link may be in place between a troubleshooting device held by a person located at a service site, and a remote service center for a service provider, such as an Internet service provider. The local wireless link may be in place between the person at the service site and the equipment needing service, such as a DSL model provided by the service provider. Establishing the multiple links allows the service provider to troubleshoot the equipment, without incurring the substantial cost of sending a specialized service technician to the service site. As examples, the troubleshooting device may be a smart phone, the remote wireless link may be a cellular connection, and the local wireless link may be a Bluetooth or NFC connection.Type: GrantFiled: August 23, 2013Date of Patent: February 16, 2016Assignee: Broadcom CorporationInventor: Lowell D.

Patent number: 9197506Abstract: A system and method for Service Interoperability in Ethernet Passive Optical Network (SIEPON) energy saving statistics. Energy saving statistics can be collected from a plurality of subordinate nodes in a point-to-multipoint network through a mechanism that aggregates energy saving statistics as those energy saving statistics are reported upstream. Such aggregation of energy saving statistics can be advantageous in that the aggregated energy saving information can appear uncorrelated to individual subordinate nodes. Privacy concerns are thereby addressed.Type: GrantFiled: December 31, 2012Date of Patent: November 24, 2015Assignee: BROADCOM CORPORATIONInventors: Wael William Diab, Ryan Hirth, Lowell D.

Patent number: 8913887Abstract: In a first aspect, the method and apparatus of the present disclosure can be used to periodically and/or intermittently place one or more ONUs attached to a PON in a power savings mode so that an OTDR test can be performed. While in the power savings mode, the ONUs temporarily suspend their transmitter function and power down their upstream lasers. In a second aspect, the method and apparatus of the present disclosure can be used to coordinate the performance of OTDR during one or more periodic or intermittent discovery slots used to detect and register ONUs recently connected to the PON. Because new ONUs are infrequently connected to the PON and ONUs already registered are not permitted to transmit during the discovery windows, OTDR can be performed during these windows without impacting, to a great degree, the normal operation of the PON.Type: GrantFiled: May 30, 2012Date of Patent: December 16, 2014Assignee: Broadcom CorporationInventors: Ryan E.
