We use 1 second on FACCH and 2 seconds on SACCH when SMS is transfered
during a call on TCH. There is no impact on bandwidth, because SAPIs use
differen channels.
In order to correctly transfer SMS during SDCCH, the T200 must be raised
from 1 (SAPI 0) to 2 (SAPI 0 and 3), so T200 will not timeout before
receiving acknowledge from BTS. This is because both SAPIs share the same
ressource on SDCCH. After release of SAPI 3, T200 is lowered back to 1.
libosmocore has changed its LAI decoding from hex to decimal. This caused
wrong decoding of MCC and MNC. In order to provide required hex
transcoding, special hex encoding and decoding function are added to
mobile/sysinfo.c.

Fix:
Holger told me to do so (he knows better then me about autoconf)
- set CFLAGS and LIBS for LIBGPS in layer23
- add libgps CFLAGS and LIBS in Makefile.am for common, misc, mobile
I would have done the following (which also works):
-AC_CHECK_LIB(gps, gps_waiting, CFLAGS+=" -D_HAVE_GPSD" LDFLAGS+=" -lgps",,)
+AC_CHECK_LIB(gps, gps_waiting, CFLAGS+=" -D_HAVE_GPSD" LDFLAGS+=" -lgps" LIBS+=" -lgps",,)
This is importaint on certan cells to finish BCCH scanning. If SI2ter
indication is falsely detected, BCCH reading will timeout, because no
expected SI2ter is received.
Basically, there were two commands in an "else" block without brackets,
causing the
"end = 1023+299"
command to execute regardless of the state of index.

Test showed that loosing the signal in dedicated mode caused a complete
rescann of all cells. By keeping the cell selected, the process can use
the neighbour cell informations to do a quick search for the best cell
afterwards.
If network will not respond to (additional) service request, the timeout
will abort the pending MM connection and return to the state before the
MM connection was requested or wait for network command.
There is no support for TS 04.14. A logging message will inidcate this,
if a tester requests test functions. A STATUS message will be sent
as it is for for other usupported protocol types received.

In case the SMS Service Center Address is not set in the config, the
Address from the SIM card is used. The mobile checks if either one is
defined, otherwise it will refuse sending SMS.
Since records of SIM are read, this patch includes fixes to talk
correctly with the SIM client.

Both MO and MT SMS are supported.
Transmission an reception can be controlled via VTY:
en
sms 1 <destination> <text>
All received SMS are stored in "~/.osmocom/bb/sms.txt".
SMS transmission is performed on SAPI 3 datalink, using DCCH or ACCH.

RR now handles SAPI 3 datalink.
MM connections now have and individual sapi, so MM can use right SAPI
for communication with other layers, as well as releasing the right
MM connections in case of link release.

If location updating (attachment) fails, the mobile returnes into idle
state. Because the SIM may be valid in this location area, the mobile must
check if the SIM is already attached. If not it may not change to normal
service.

When mobile exits, a list of allocated memory chunks are dumped to
stderr. This helps to find talloc_free / msgb_free leaks.
During process, a SIGUSR1 or SIGUSR2 can be used to dump currently
allocated memory chunks.

We alias the uint8_t buf[..] to a uint16_t* which is violating
the aliases rule of C. Use an explicit memcpy to copy the first
two byte of the buffer. GCC 4.6.2 (debian) is clever enough to
use a normal load does not generate a memcpy call.
