28、intended to support frequency optimization in order to minimize interference in the radio network. The interference level in GSM networks has to be kept to a minimum in order to use the frequency spectrum in an efficient

29、 way, and to increase the capacity of the network. The speech quality and the amount of dropped calls are directly affected by the interference level. </p><p>  The FAS is an optional feature and aims at rel

30、ieving the user from the burden of frequency optimization. By monitoring the up- and downlink interference environment in the network, FAS can find bad frequency allocations, both for BCCH (Broadcast Control Channel) and

31、 Traffic Channel (TCH) carriers, and replace them with better ones. </p><p>  New FAS recordings are created and started in the RNO and recording results are collected by RNO. After the recording is complete

32、d, the result values are reported to OSS where they are processed and presented to the user in reports and in geographical maps. The recording results can be uplink interference data, downlink Percentage Interfered Traff

48、 The accuracy of the measurements is critical to making reliable handover decisions. If the number of neighboring cell relations is too high, measurement accuracy decreases. All the relations that can be good handover ca
