• A particular nanoBTS is not operating correctly. Manual mode is used to
investigate its configuration and diagnose and fix the problem.
6.3.3.2 The Unknown BTS Mode
Normally the BTS Database contains entries for specific nanoBTSs. In particular the
DHCP server will only normally only supply an IP configuration to a nanoBTS whose
MAC address matches that explicitly specified in the BTS Database entry.
There is a special “Unknown BTS” mode of operation in which the BTS Database
contains just one special entry. This special entry acts as if it had a wildcard MAC
address, and the DHCP server will recognise any nanoBTS that asks for an IP
configuration.
IN THIS MODE THERE IS NOTHING IN BTS Installer TO STOP THE
CONFIGURATION OF ANY nanoBTS THAT IS CONNECTED TO THE
NETWORK FROM BEING CHANGED.
This special mode of operation is designed to be used when only one nanoBTS at a
time is connected to the computer running BTS Installer, usually on a tiny private
network, perhaps just a crossover cable. It bypasses the normal safeguards that BTS
Installer uses to ensure that it makes configuration changes only to BTSs that are
identified as those that the user has specified.
There is no way to create this special BTS Database entry from the graphical user
interface; it must be loaded from a configuration file. There is no particular indication to
the user that BTS Installer is in Unknown BTS Mode, except that the Find and New
buttons in the BTS Status section of the user interface are disabled.
6.3.3.3 Proxy and Direct Operation
There are various network configurations in which BTS Installer may be used, and the
general design of the IP network configuration is outside the scope of this document.
In some network configurations BTS Installer is on the same network as the
nanoBTSs, in that there is an IP route from BTS Installer to the nanoBTSs. In such
configurations BTS Installer can communicate directly with the nanoBTSs in direct
connection mode.
There are two different types of direct connection that BTS Installer can make to a
nanoBTS: a normal TCP connection or a secure SSL connection.
In other network configurations BTS Installer and the nanoBTSs are on different
networks, and there is no IP routing between the two. Typically in this scenario the
BSC will be multihomed, and will have an interface to each network but will not route
IP packets between the two networks. An optional system component, the BTS
Installer Proxy, can be installed as part of the BSC, and will forward requests from
BTS Installer to the nanoBTSs and return the replies. In such configurations BTS
Installer communicates with the nanoBTSs in proxy mode.
There are two different types of proxy that might be present on a BSC: a Primary OML
Proxy and a Secondary OML Proxy. Which can be used depends on the network
configuration.
