Patent number: 11323958Abstract: If a cellular base station detects that it is about to shut down, either because no mobile terminals are within range, or because of a loss of power, for example because a user has deliberately switched it off, it first broadcasts a report that is about to shut down. This broadcast signal is picked up by the neighboring cells and used to update their neighbor lists, thus avoiding a false alarm which would otherwise be generated by the neighbors and transmitted to a centralized Operation Administration and Maintenance system when the shut-down cell fails to be detected on the next sampling cycle. The neighbors can then retain the shut-down base station in the neighbor list.Type: GrantFiled: February 24, 2017Date of Patent: May 3, 2022Assignee: British Telecommunications Public Limited CompanyInventor: Dalia Abouelmaati

Patent number: 11153769Abstract: Network addresses which are frequently accessed by user terminals are monitored by a network access point to which the terminals are connected, and the network access point then makes attempts to access the network addresses from time to time and makes reports to a network management system of any such network addresses that fail to respond. This increases the likelihood of detection and reporting of failures of active addresses before the user has need of them.Type: GrantFiled: January 30, 2018Date of Patent: October 19, 2021Assignee: British Telecommunications Public Limited CompanyInventor: Dalia Abouelmaati

Patent number: 10912004Abstract: In a cellular telecommunications system, outage management is managed in respect of each cell B by a nominated neighbor cell A, the identity of which is recorded in a neighbor list for cell B. If a cell C, D, other than the nominated neighbor, detects a suspected outage in a cell B, the cell detecting the outage identifies the nominated neighbor A from the neighbor list of cell B, and transmits an outage report to the nominated neighbor cell A, which coordinates a handover and outage management process. This avoids multiple detections of the same outage resulting in conflicting attempts to manage the recovery process.Type: GrantFiled: October 4, 2017Date of Patent: February 2, 2021Assignee: British Telecommunications Public Limited CompanyInventors: Dalia Abouelmaati, Richard Mackenzie, Michael Fitch

Patent number: 10420024Abstract: An outage of a cellular base station is detected by a neighboring base station when a beacon signal previously stored by the neighbor in respect of the base station being monitored is compared with the result of a subsequent search for that signal and found to have deteriorated or ceases to be detected. If the search identifies such an event, the search is repeated at a shorter interval and an outage is reported to a management center if the base station also fails to be detected on subsequent consecutive sampling cycles. This avoids false alarms from reboots and other transitory losses of signal that would be caused by an outage report based on a single loss of signal.Type: GrantFiled: February 24, 2017Date of Patent: September 17, 2019Assignee: British Telecommunications Public Limited CompanyInventor: Dalia Abouelmaati
