Wow! It works! And I can send SMS with the NE110 phones too!
Maybe could it be a solution to set lctype to GSM_LCHAN_SDCCH if the
phone tried to send an SMS?
Harald probably knows the details better, but the basic problem is
that the phone does not tell you exactly what channels it needs
when it sends the Channel Request, at least if NECI is set to 0
(new establishment causes are not supported). So the channel
allocator allocates a TCH channel, to be able to handle everything
(SMS and Voice).
One solution for this is to switch from Very Early Assignment to
other assignment procedures. I think Holger and Harald have plans
to support this.
However there also seems to be a different solution: You can set
NECI to 1, this way the phone can tell you in more detail what
it wants. I have not done extensive tests, but it seems that
this could solve the problem without the need to change the
code. You just have to set "neci 1" in the OpenBSC configuration
file.
Best regards,
Dieter

Hi, Dieter!
Harald probably knows the details better, but the
basic problem is
that the phone does not tell you exactly what channels it needs
when it sends the Channel Request, at least if NECI is set to 0
(new establishment causes are not supported). So the channel
allocator allocates a TCH channel, to be able to handle everything
(SMS and Voice).
So the theory. Unfortunately (as always!) the practice is
other... :D
One solution for this is to switch from Very Early
Assignment to
other assignment procedures. I think Holger and Harald have plans
to support this.
Aha!
I did some tests, to know which Channel Requests are sent in the
specific context, and I see that OpenBSC (with neci == 0!!) get 0xE5 or
0xE6 by calling and 0xE1 by SMS sending.
Unfortunately, the mask is the same, and the function
get_ctype_by_chreq can't decide what the phone says...
Maybe an "if(ra == 0XE1)" will help to correct the problem, but it is a
VERY BAD solution...
However there also seems to be a different solution:
You can set
NECI to 1, this way the phone can tell you in more detail what
it wants. I have not done extensive tests, but it seems that

file.
I try with neci 1 in my config!
Thanks a lot for the suggestion!

Hi, all!
I can confirm, that "neci 1" solve my problem!
I can call and send SMS without any problem, from the NE110, too!
Thanks Dieter! Your suggestion was VERY good!
