Method and apparatus for realizing base station interference signal code power abnormity detection

Abstract

The invention discloses a method and apparatus for realizing base station interference signal code power (ISCP) abnormity detection. The method comprises the following steps that: size relations of an ISCP value of a base station target cell and a first threshold value, of the ISCP value of the base station target cell and a second threshold value, and of the ISCP value of the base station target cell and a third threshold value are determined; when the ISCP value is larger than the first threshold value, all channels of a radio remote unit (RRU) are closed; if the ISCP value is less than the third threshold value after all the channels of the RRU are closed, the current abnormity is determined as a first abnormity cause; and otherwise, abnormity detection is carried out by an uplink single tone sending operation; when the ISCP value is less than the second threshold value, whether the RRU channels are closed; if so, the current abnormity is determined as a second abnormity cause, and otherwise, abnormity detection is carried out by an uplink single tone sending operation. With the method and the apparatus, the abnormity detection process is simplified and the abnormity detection positioning efficiency can be effectively improved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and device for realizing abnormal detection of base station Interference Signal Code Power (ISCP, Interference Signal Code Power). Background technique [0002] Base station ISCP is an indicator that reflects the interference of the cell, and is used to detect whether the uplink path of the base station is normal; usually, the ISCP parameter is in the normal range within (-115dBm, -85dBm), and it is considered abnormal if it is greater than -85dBm or less than -115dBm. An abnormality (high or low) of the uplink signal of the base station will cause problems such as the inability of the user to access or the user's call drop. However, because the data flow of the uplink channel passes through many modules, there are many reasons for the abnormality, such as: External interference, equipment hardware failure, BBU (Building Base band Unit, indoor baseba...

AI Technical Summary

Problems solved by technology

An abnormality (high or low) of the uplink signal of the base station will cause problems such as user inability to access or user drop, but because the uplink data flows through many modules, there are many reasons for this abnormality, for example: External interference, equipment hardware failure, BBU (Building Base band Unite, indoor baseband processing unit) or RRU (Radio Remote Unit, wireless remote unit) software module abnormality, etc.

[0003] For the detection and location of the above-mentioned ISCP abnormality, the prior art usually adopts a manual method, that is, a simple manual reset method is used to handle it, and this method will often destroy the system status when the ISCP is abnormal; at the same time, due to the abnormality of the ISCP Multiple subsystems are often involved, and because of the wide variety of BBU and RRU products, if manual reset is used to locate abnormalities, not only the cost is too high, the positioning process is cumbersome, but also the ISCP positioning efficiency is low
