Problems solved by technology

However, as long as the abnormality of the state of the resource is not repaired, even in the standby wireless transceiver function part (standby A card) 21, the abnormality of the transmission output level will be detected in the same way and become a failure state.
As a result, a system outage occurs

Embodiment Construction

[0020] The outline of the present invention will be described with reference to FIG. 2 . In FIG. 2 , the same reference numerals are assigned to the same parts as those in FIG. 1 . As will be seen from the description below, the CDMA radio base station 100 of the present invention is characterized in that the radio transceiver function unit (A card) 60 and the call processing monitoring control function unit (D card) 70 have new functions. That is, the CDMA radio base station apparatus 100 includes a call processing monitoring control function unit (D card) 70 capable of monitoring resource states. The call processing monitoring control function unit (D card) 70 constantly monitors the status of resources set in the baseband signal processing function unit (B card) 30 . That is, it is monitored whether the resources are normally set in the baseband signal processing function unit (B card) 30 and output to the baseband signal diffusion function unit (C card) 40 normally. Here...

Abstract

When a radio transmission / reception function section (card A) (60) has detected an error of the transmission output level, a call processing monitoring control function section (card D) (70) notifies whether the resource state is normal to the radio transmission / reception function section (card A) (60). When an abnormal resource state is notified, the radio transmission / reception function section (card A) (60) stops transmission if an abnormal resource state is notified and performs switching to a back-up radio transmission / reception function section (back-up card A) (21) if a normal resource state is notified.

Description

technical field [0001] The present invention relates to a method for avoiding false detection of an abnormal transmission output level in a CDMA radio base station device and a radio base station device. Background technique [0002] A conventional CDMA radio base station apparatus will be described with reference to FIG. 1 . The CDMA wireless base station device 10 is equipped with a wireless transceiver function part (A card) 20, a baseband signal processing function part (B card) 30, a baseband signal diffusion function part (C card) 40, and a call processing monitoring control function part (D card) In addition to 50, a spare wireless transceiver function part (a spare A card) 21 and a spare baseband signal processing function part (a spare B card) 31 are also provided. [0003] In the CDMA radio base station apparatus 10, in order to ensure stable channel quality, it is necessary to monitor the abnormality of the transmission output level. In order to detect an abnorm...
