Patent number: 9268630Abstract: Systems, methods and computer readable media can operate to protect against non-functional software updates. Some implementations can provide for storing both a new load and a previous load in non-volatile memory of a customer premise equipment (CPE) device. After storing both loads, a software update can be applied to the CPE device, the software update comprising the new load to be used as a primary load replacing the previous load used by the CPE device. The device can then be rebooted using the new load as the primary load and a determination can be made whether the CPE device is operating correctly using the new load as the primary load. If the CPE device fails to operate correctly using the new load as the primary load, the CPE device can revert to the previous load as the primary load.Type: GrantFiled: April 26, 2013Date of Patent: February 23, 2016Assignee: ARRIS Enterprises, Inc.Inventor: Robert Allen Walston

Patent number: 9094123Abstract: After a user device unsuccessfully attempts to establish upstream communication with a central network equipment downstream frequency to which it has tuned, an identifier corresponding to the tuned-to downstream frequency is removed from a cache of the user device. The frequency identifier stored in the cache typically corresponds to a frequency to which the user device has previously successfully tuned. The frequency identifier is removed from the cache after a predetermined attempt period, which may be determined by the number of attempts to establish communication that are made after previous unsuccessful attempts.Type: GrantFiled: October 26, 2010Date of Patent: July 28, 2015Assignee: ARRIS Enterprises, Inc.Inventor: Robert Allen Walston

Patent number: 9025507Abstract: An association table associates each program stream of a plurality of program streams with a MAC domain, with a channel frequency and with a multicast address. If a subscriber device selects a content program different from a current program, a determination is made whether the new program is serviced by a different MAC domain than the one serving the current program. If the selected new program is not serviced by the same domain that is serving the current program stream(s), the current MAC domain is informed that the subscriber device is ending the session therewith, the new frequency is tuned by the subscriber device and new content is received immediately after the new frequency is tuned. The subscriber device registers with the new MAC domain after receipt of new content has begun.Type: GrantFiled: July 29, 2011Date of Patent: May 5, 2015Assignee: ARRIS Enterprises, Inc.Inventors: Allen Walston, Carol Ansley

Patent number: 8838186Abstract: Processing circuitry in a user device detects information concerning periodic station maintenance opportunities provided by a CMTS. The processor determines a quiet interval between the end of one station maintenance opportunity and the beginning of the subsequent opportunity. If offsite power to the user device is lost, the processor counts down a predetermined amount of time with a first timer and then periodically turns off RF circuitry of the device after the ending of a maintenance opportunity that follows the counting down of the first timer. The processor then begins a second timer to count the quiet interval. After counting down the quiet interval, the processor restores battery power to the RF circuitry for the duration of the maintenance opportunity. If an off-hook condition occurs while the second counter counts down the quiet interval, the processor restores battery power to the RF circuitry.Type: GrantFiled: March 19, 2007Date of Patent: September 16, 2014Assignee: ARRIS Enterprises, Inc.Inventor: Allen Walston
