Measurement Counter
A301F: CELL_TCHF_SUCC_TIMES_SPEECH
A301HH: CELL_TCHH_SUCC_TIMES_SPEECH
Description
In the immediate assignment procedure, an MS reports a FIRST SABM frame to the BTS on the seized signaling channel (SDCCH, TCHF, or TCHH). Through this frame, the MS notifies the BTS that the radio link layer has entered the multiframe link setup state. The BTS returns a UA frame to the MS and sends the BSC an EST IND message to notify the BSC that the link is established on the Um interface.
If the channel type is TCHH or TCHF, A301F TCHF Seizures for Speech Service and A301H TCHH Seizures for Speech Service are measured respectively.
Unit
Integer number or integer
Measurement Point
After receiving the setup indication message from the BTS, the BSC measures the TCHF Seizures for Speech Service or TCHH Seizures for Speech Service of different access reasons (MOC Non SMS, Emergency Call, Call Re-establishment) and channel types according to the type of the Layer 3 information in the message. This counter is measured at point C in Figure 1.
On receiving the assignment request message from the MSC, the BSC measures the TCHF Seizures for Speech Service or TCHH Seizures for Speech Service based on the channel type if the access cause is MTC or SS. See measurement point A in Figure 2.
