<p>Length of IND in bits = 5</p>
<p>for the verification of sequence numbers in the USIM:<br />Length of the array: a = 32</p>
<p>In our case value 3 has been used which is low and does not satisfy requirement related to Length of IND in bits.</p>
<p>When using higher value (i.e. 64) successful re-synchronization is performed. Please see attached resync_succ.log file.</p> pySim - Bug #1836: Re-Synchronization does not work as described in sysmousim-manualhttps://projects.osmocom.org/issues/1836?journal_id=25702016-12-07T13:54:07Zwirelesss
<ul><li><strong>% Done</strong> changed from <i>40</i> to <i>50</i></li></ul><p>This update comes as an addition to the above mentioned comment and for the sake of clarity.</p>
<p>A SQN value higher than the one determined by the AUTS procedure must be used as input to <strong>osmo-auc-gen</strong> to generate a new authentication quintuples (-s parameter).</p>
The SQN value has to be such one that at least causes a changes of bit 2 <sup>5</sup> or bit 6.<br />Please refer to 3GPP TS 33.102 Release 11, annex C. 3.2, "Management of sequence numbers which are not time-based", where the following parameter values are suggested for reference:
<ul>
<li>Length of IND in bits = 5</li>
<li>Length of the array: a = 32</li>
</ul>
<p>The last one relates to verification of sequence numbers in the USIM. Minimum value that satisfies the requirements is a value that is achieved by applying incremental step of 32.</p> pySim - Bug #1836: Re-Synchronization does not work as described in sysmousim-manualhttps://projects.osmocom.org/issues/1836?journal_id=25802016-12-08T19:02:48Zwirelesss
