From 3e23ddf88b38f9316b61daff6f8f41e57e883a14 Mon Sep 17 00:00:00 2001 From: Jacob Erlbeck Date: Mon, 11 Aug 2014 15:07:37 +0200 Subject: gbproxy: Parse Detach Request messages GSM 24.008 also allows a P-TMSI field in Detach request messages. This patch adds gbprox_parse_gmm_detach_req() to parse Detach Request messages which sets the ptmsi field if the IE is present. In addition, when power_off is set to 1 (MO only), the invalidate_tlli field is set, since Detach Request message is expected in this case. The second detach test (see 'RA update') is modified to use power_off instead of relying on a Detach Accept from the network. To make this work, the PTMSI of the RA Update Accept is fixed to match the TLLI of the Detach Request.
