== Objects and their relationship ==
|

|
||||
=== MSC ===
|
||||
- MSC has a VLR, HLR, BSCConfig, MSCBSCConnectionHandler
|
||||
- MSC can serve a BSC on TCP depending on the MSCConfig with
|
||||
the BSCListener
|
||||
|
||||
=== BSCListener ===
|
||||
- BSCListener will wait for incoming connections and hand them
|
||||
to the MSCBSCConnectionHandlerMSC. This will try to find the
|
||||
configured peer and might do the connection.
|
||||
|
||||
=== MSCBSCConnectionHandler ===
|
||||
- Get's a new connection from the BSCListener, will fork and
|
||||
serve the BSC using the BSCIPAConnection. This is done to
|
||||
remember if a given system is already connected or not.
|
||||
|
||||
=== BSCIPAConnection ===
|
||||
- Handles IPA mux/demux on the socket...
|
||||
- Has a SCCPHandler
|
||||
- Uses GSMProcessor to process the GSM part of it.
|
||||
|
||||
=== GSMProcessor ===
|
||||
- Handles GSM connections, transaction and such.
