IntraCell AMR TCHF-TCHH Traffic Threshold Step - Modification Rules None Configuration Policy If this parameter is set to Yes, the AMR TCHF-TCHH handover algorithm is enabled and an AMR call can be handed over from TCHF to TCHH to relieve network congestion. If this parameter is set to No, the AMR TCHF-TCHH handover algorithm is disabled and an AMR call cannot be handed over from TCHF to TCHH. Thus, network congestion cannot be relieved through TCHF-TCHH handover. Recommended Value None Parameter Relationship None BSC Feature None Parameter Class Parameters About Radio Resources Caution This parameter is available only when HO Control Switch is set to HO Algorithm II. This parameter is invalid when the HO Control Switch is set to HO Algorithm I. Parameter Name IntraCell AMR TCHF-TCHH Traffic Threshold Description When the load of a cell exceeds this threshold, the BSC initiates an AMR TCHF-TCHH handover. When the load of the network exceeds this threshold, some calls may be handed over from TCHF to TCHH. GUI Value Range [0,100] Default Value 75 Unit None Step - Modification Rules None Configuration Policy If this parameter is set to a too great value, many calls cannot be handed over from TCHF to TCHH when the load of the network increases in a short time. Thus, network congestion cannot be relieved in time.

This parameter is invalid when the HO Control Switch is set to HO Algorithm I. Parameter Name IntraCell TCHF-TCHH Ho Duration(s) Description If the load of a cell exceeds the threshold, the BSC hands over all the qualified calls in the cell from TCHF to TCHH during the time specified by this parameter. GUI Value Range [0,600] Default Value 5 Unit Seconds Step - Modification Rules None Configuration Policy If this parameter is set to a too small value, the duration of an AMR TCHF-TCHH handover is short after the handover is triggered. Thus, few MSs can be handed over from TCHF to TCHH, and network congestion cannot be relieved in time. If this parameter is set to a too great value, the duration of an AMR TCHF-TCHH handover is long after the handover is triggered. Thus, even the MSs on the edge of the cell are handed over from TCHF to TCHH, and the handover quality deteriorates.

This parameter is invalid when the HO Control Switch is set to HO Algorithm I. Parameter Name IntraCell TCHF-TCHH Ho Period(s) Description The value range of this parameter is the same as that of IntraCell TCHF- TCHH Ho Duration(s), and the value of this parameter must be smaller than that of IntraCell TCHF-TCHH Ho Duration(s). GUI Value Range [0,600] Default Value 1 Unit Seconds Step - Modification Rules None Configuration Policy If this parameter is set to a too small value, the handover zone is enlarged in a short time, and thus many MSs are handed over from TCHF to TCHH. If this parameter is set to a too great value, the handover zone is enlarged slowly and it takes a long time to initiate a TCHF-TCHH handover. Thus, network congestion cannot be relieved in time.
