Andreas Eversberg c50543b18a Improved generation of SYSTEM INFORMATIONs 2* and 5* for neighbour bands
In addition to SI 2 and SI 5, the SI 2ter and 2bis is generated, if
neighbour cells in other bands exist. Also it is indicated in the rest
octets of SI3, that SI 2ter is used. If no neighbour cell in a different
band exists, the SI 2ter and SI 5ter is omitted.

A special case is P-GSM range (channels 1-124). To be compatible with
older phones, SI 2bis and SI 5bis is used. If the BCCH lays inside the
P-GSM band, only neighbour cells of the P-GSM range are included in
SI 2 and SI 5. If neighbour cells exist in the same band (900), but lay
outside the P-GSM range, the SI 2bis and SI 5bis is used to extend the
list of neighbour cells. The extension is also indicated in SI 2 and
SI 5. If the BCCH lays inside the P-GSM range, but no neighbour cell
exists in the same band outside the P-GSM range, the SI 2bis ans SI 5bis
are omitted.

About OpenBSC
=============

OpenBSC is a minimalistic implementation of the GSM Network, with
particular emphasis on the functionality typically provided by the BSC,
MSC, HLR, VLR and SMSC.

Its currently supported interfaces towards the BTS are:

 * Classic A-bis over E1 using a mISDN based E1 interface. In other
   words, you can connect existing GSM Base Transceiver Station (BTS)
   through E1 to OpenBSC.  So far, we have only tested the Siemens BS-11
   Test reports with other BTS are much appreciated!

 * A-bis over IP as used by the ip.access nanoBTS product family

You can find the project documentation at http://openbsc.gnumonks.org/

This project is still in its early days, and there are lots of areas where it
doesn't behave as per GSM spec.

libosmocore
===========

Please note that as of March 2010, OpenBSC has a dependency to a library
called "libosmocore".  You can obtain that library from

	git://git.osmocom.org/libosmocore.git
