Publication number: 20190246329Abstract: 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: ApplicationFiled: October 4, 2017Publication date: August 8, 2019Applicant: British Telecommunications Public Limited CompanyInventors: Dalia ABOUELMAATI, Richard MACKENZIE, Michael FITCH
