Subject: New Mobile Phone Models - Latching Issue using OSMO-NITB - Connection
 Drops approx after 3 Minutes
Message-ID: <82EE2E43-6059-4888-BA16-81480C8E6BBF@entropysolution.com>

Hi Community,

Does anyone experiences, in newer phone models, that after a successful latched to OSMO-NITB, it will dropped its connection in a few minutes?

We have experienced this issue to the following mobile phone models:


  1.  iPhone X - Software Version - 13.3 (Connection drops approximately after 3 minutes)
  2.  Samsung S10 (Connection drops after 1 - 3 minutes)
  3.  Samsung Note 9


Best Regards,

Ron Menez

Hi Vadim,

22:22 < fixeria> LaF0rge: oh, we already have 'template anytype' in pcu/PCUIF_RAW_Components.ttcn
22:23 < fixeria> ... and that's my code :P
22:26 < fixeria> yay, it even compiles
22:39 < fixeria> but does not work as expected: "error: Type mismatch: a value or template of type
                 `@Osmocom_Types.anytype' was expected instead of `integer'"
22:41 < fixeria> I am testing against uint8_t which is defined exactly in Osmocom_Types :/
22:52 < fixeria> LaF0rge: pespin_: https://pastebin.com/EL9JUqq9

Please see https://www.eclipse.org/forums/index.php?t=msg&th=1074288&goto=1721710&#msg_1721710
for how to use anytype in TITAN

So if I modify the last line of Osmocom_Types.ttcn with your patch from
https://pastebin.com/EL9JUqq9 attached to this:

} with { encode "RAW"; variant "FIELDORDER(msb)" extension "anytype OCT1" }

The errors about the non-existant OCT1 field in anytype are gone.

This is of course not nice, but maybe a work-around to explicitly list those types
at the end for now?

Regards,
	Harald

Hi Harald,

> Please see https://www.eclipse.org/forums/index.php?t=msg&th=1074288&goto=1721710&#msg_1721710
for how to use anytype in TITAN

thank you! I was too sleepy to investigate. What a surprise from TITAN!

> The errors about the non-existant OCT1 field in anytype are gone.

As an experiment, I tried to move the test case to BTS_Tests.ttcn and
TITAN generated C++ code without any errors. Nice! But now g++ fails
to compile that code:

Osmocom_Types.cc:1389:24: error: ?OCT1? was not declared in this
scope; did you mean ?General__Types::OCT1??

so I am giving up on this.

> This is of course not nice, but maybe a work-around to explicitly list those types

I think for now it's fine to have one function per type as Pau did in
[1]. I was just looking for a way to generalize this somehow. The
ternary operator would be way more elegant and universal solution, so
I will do my best to move this forward as soon as I have time.

With best regards,

I think some phones drop out of the network when they cannot establish both a
CS and a PS attach, but it's just guessing and I have no details on these
particular models.

Me configuration is:
