• When running automatic configuration via a BTS Installer Proxy,
performance may be lower than that achieved with a direct connection between
BTS Installer and the nanoBTS. The BTS Installer Proxy may be configured to
allow only a limited number of simultaneous connections, in order to control the
load on the BSC; if this is the case then automatic configuration will operate on
only a limited number of nanoBTS at once, with others having to wait until the
first batch have been configured (this is all handled automatically by BTS
Installer). In addition, when configuring multiple nanoBTS via a BTS Installer
Proxy, some of the default timeouts may prove to be inadequate – for example
when downloading new software to many nanoBTS simultaneously via a BTS
Installer Proxy it was found in one experiment that better results were achieved
by setting the GSM 12.21 Procedures timeout to 30 seconds and the Software
Download Window to 5.
The following additional restriction applies to the Primary OML Proxy:
• BTS Installer can only communicate via the Primary OML Proxy with a
nanoBTS which is already configured to the point at which it has made an OML
connection to the BSC. If there is a problem with the BTS such that it cannot
set up a connection with the BSC, for example its primary OML addresses are
set incorrectly, then BTS Installer will not be able to reach it using the Primary
OML Proxy.
• The SW Activate feature on the Configure BTS dialog does not work when
connected via a Primary OML Proxy.
The following additional restriction applies to the Secondary OML Proxy:
• If there is a NAT (network address translation) in the network between the
nanoBTS and the BSC then the secondary OML proxy will not be able to
contact the nanoBTS.
When BTS Installer starts in proxy mode it investigates whether a proxy of either or
both types is running on the BSC platform. It will then use the proxies that it has
detected when making any subsequent connection to a nanoBTS. If it can’t find either
proxy it will give up trying to run in proxy mode and will revert to direct mode.
If BTS Installer determined when starting up that both types of proxy were running,
then it will first try to make a connection to a nanoBTS using the Primary OML Proxy,
and if that fails it will try again using the Secondary OML Proxy.
