Fault detection method, cellular base station and cellular communication management processor

Abstract

Fault detection method, cellular base station and cellular communication management processor. In a cellular telecommunication system, outage management with respect to each cell B is managed by recommending a neighbor cell A, whose identity is recorded in the cell B's neighbor list. If cells C, D other than recommended neighbors detect a suspicious outage in cell B, the cell that detected the outage identifies recommended neighbor A from the neighbor list of cell B and sends an outage report to recommended neighbor cell A, which Coordinates the handover and interrupt management process. This avoids conflicting attempts to manage the recovery process caused by multiple detections of the same outage. The selection of recommended neighbors for cell B can be done autonomously by the cell itself or by a centralized processor (2), and can be done in a way that supports network resilience, i.e., avoiding reciprocity between cells, using a second backhaul system for connections to Cell B of the first backhaul system chooses to recommend neighbor A and avoids using cell E with intermittent or transient connections to the network.

Description

technical field [0001] The present invention relates to cellular communications, and more particularly to maintaining cellular communications coverage during shutdown of one or more base stations. When this happens, any mobile station registered with the base station that has been switched off, whether currently calling or on standby, must register with another base station within range so that calls can continue to be connected to and from the mobile station connect. Background technique [0002] In a normal handover, the base station where the handoff occurs controls the process, for example, of identifying when signal quality has degraded, identifying (e.g., from a "neighbor list") which base stations it can handover to, and how the mobile unit identifies them , and the handover process itself is synchronized. If the base station is turned off unexpectedly, the process cannot be done. Instead, the mobile unit must initiate the process of searching for any base stations...

AI Technical Summary

Problems solved by technology

This extra negotiation step is inconvenient because it requires additional processing time, which may delay the initiation of the recovery process, increasing the duration of the service interruption

This step may also have to be done multiple times as more base stations detect the faulty base station and try to enter the negotiation process
