634 Matrix ETERNITY NE System Manual
BCCH Selection
BCCH Selection feature enables you to lock the Mobile Port of SARVAM UCS to a particular cell or channel or BTS
(Base Transceiver Station) to ensure better network availability and minimize call drops due to bad signal/ network
failure.
This feature is supported only when GSM
104
or LTE is selected as the Network Preferred Mode for the
Mobile Port. See “Mobile Trunks”.
How it works
In the GSM network, each BTS is assigned one particular channel called as ARFCN (Absolute Radio Frequency
Channel Number), which is transmitted by BTS in BCCH (Broadcast Control Channel).
Now, when SARVAM UCS is switched on, the Mobile Port gets registered with the network on a particular BTS
which has the highest signal strength. However, the signal strength is not consistent. It keeps fluctuating, resulting
in call drop or poor voice quality.
Therefore, to avoid this, SARVAM UCS enables you to lock the Mobile Port to a particular cell or channel manually
after checking Signal Strength and Signal Quality of each cell.
How to configure
To lock the Mobile Port to a cell or a channel,
• Login as System Engineer.
• Under Advanced Settings, click Mobile Trunks.
104. BCCH Selection will not be supported if QUECTEL UC20G module is installed in your system.
