Embodiment Construction

[0031] In the following description, for illustrative and non-limiting purposes, specific details are set forth such as specific nodes, functional entities, techniques, protocols, standards, etc., in order to provide an understanding of the described techniques. Those skilled in the art will appreciate that other embodiments may be practiced without departing from the specific details disclosed below. The present technique is described in the context of Long Term Evolution (LTE) for UMTS to provide an example and non-limiting context for illustration. The idea of ​​the invention is equally applicable to many types of cellular systems consisting of multiple base stations, where accurate and economical detection of dormant cells is necessary but difficult to provide.

[0032] In other instances, detailed descriptions of well-known methods, devices, techniques, etc. are omitted so as not to obscure the description with unnecessary detail. Individual functional blocks are shown i...

Abstract

The wireless communication network automatically tests itself against dormant cells. Tests are performed by assigning a base station to periodically act as a terminal, contact its neighboring base stations, and perform a set of typical traffic scenarios as a mobile station. As a result of the traffic situation, the investigated base station detects neighboring base stations that cannot carry traffic. Information about the dormant cell is then sent from the base station to the operation and maintenance system.

Description

technical field [0001] The present invention relates generally to radio communications, and more particularly to methods and apparatus for monitoring cells in a wireless communications system. Background technique [0002] Wireless communication networks are well known and growing in popularity. For example, mobile terminals such as cellular telephones communicate wirelessly through base stations or Node Bs in WCDMA that are associated with different cells or sectors in a geographic area. Due to the increasing popularity and increased competitiveness of wireless communications, system reliability and availability to end users is increasingly important. [0003] The cost of operating a radio network is an incremental part of the operator's expense (OPEX). Further increases in OPEX are expected due to the number of base stations, their geographic distribution over large areas and the nature of wireless links requiring complex and sophisticated fault detection and recovery sc...
