R3505B:CELL_CH_CONVERT_REQ_NUM_HR-FR
Because the number of the initially configured TCHFs and TCHHs cannot meet the actual traffic requirements, the BSC enables the TCHHs to be adjusted to TCHFs in certain conditions.
In certain conditions, the initially configured TCHHs can be adjusted to TCHFs and the corresponding TCHFs can be adjusted to TCHHs.
The trigger conditions of the adjustment from TCHHs to TCHFs during channel assignment are as follows:
The system allows the dynamic data adjustment.
The requested type of channels is TCHF, but there is no qualified TCHF available.
There are at least two qualified idle TCHHs.
The adjustment procedure is as follows:
Select two TCHHs available for adjustment. If there are no channels available for adjustment, the adjustment fails.
Convert the channel type and update the channel resources. Then perform configurations on the channels under the BTS. When the conversion of the channel type is complete, the BTS sends a status change report to the BSC.
If the channel is available, the idle TCHF converted by the BSC can be used for channel assignment. The channel adjustment is complete and the two TCHHs are adjusted to one TCHF.
Integer number or integer.
Before the channel assignment, this counter is measured when the adjustment from two TCHFs to a TCHF is initiated.
This is an original counter without involving any formula.
