Jacob Erlbeck fb26c60a2f sgsn: Avoid duplicated Attach Accept messages Currently each received Ident Resp triggers an Attach Accept/Reject if IMSI and IMEI are known. This has led to duplicated Attach Accept messages when used with the gbproxy (IMSI acquisition active) and with certain mobile equipment (iOS). This patch modifies gsm48_rx_gmm_id_resp to discard Ident Resp messages if all required information (IMEI and IMSI) has been gathered.

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
