From 69cadc976dd9eb48600ddaa5501f6ac629559e8a Mon Sep 17 00:00:00 2001
From: winckel <winckel@eurecom.fr>
Date: Sun, 22 Dec 2013 12:54:34 +0000
Subject: [PATCH] Added rsrq and rsrp to BCCH DATA IND message to allow
reporting of signal level and quality to upper layers. Added
NAS_CELL_SELECTION_CNF response for NAS after successful decoding of SIB1.
