OpenBSC USSD external application
by Rowan Phipps 15 Sep '17

15 Sep '17

Hi, I’ve been looking into getting ussd working with an external application. I found a branch from last year (fairwaves/sup-ussd) that looks like it has implemented most of ussd sessions and possibly communicates with an external application. Does anyone know if it was finished or what still needs to be done? I also found a python script called ussd_example.py which looks like it is supposed to act as a gateway and receive used connections from openbsc. Is this correct and did it work or am I misunderstanding its purpose? Thanks! - Rowan Phipps

vty: indent to exit, side effect
by Neels Hofmeyr 15 Sep '17

15 Sep '17

I implemented https://gerrit.osmocom.org/3880 to use indenting for vty implicit 'exit'. There's one thing I'm sneaking in there though which I'd like to mention before I merge: The patch is storing vty parent node state. This state not only stores previous indenting, but it also stores the parent's 'node' id and 'priv' data (the node's object), and puts these back in place after going to a parent. So far our go_parent_cb()s set these, and AFAIK all of them simply put the parent's exact node and priv pointer back in place. But technically, a go_parent_cb() *could* do some magic like going to a completely different node, or re-creating a new priv pointer. By overwriting from stored state, we will override such behavior. I think we want this to happen from stored state in the future, and drop most of the go_parent_cb(). Does everyone agree? ~N

osmo-nitb / osmo-bsc ms max power dynamic value
by Ron 15 Sep '17

15 Sep '17

Hi All, Is there a way to configure the “ms max power” to a dynamic value depending on the distance of the mobile phone to the base station? For now, the default value is 12. Meaning, the base station is telling the mobile phone to transmit in the power of 12dBm either the phone is besides the base station or on the edge of the base station. If not, is there a roadmap on configuring it with a dynamic or auto value? TIA. Best Regard, Ron Menez ron.menez(a)entropysolution.com<mailto:ron.menez@entropysolution.com>

VTY tests still causing build failures
by Harald Welte 13 Sep '17

13 Sep '17

Dear all, for probably about a year (or longer) we have been putting up with VTY tests which cause builds to break under unclear circumstances. I personally believe the probability of a VTY test failing has recently increased again, and this is barely tolerable anymore. Often, rebasing/cherry-picking the given patch one or two times also doesn't work. Yet, the given patch-under-test is not even touching anything related to VTY, like In https://gerrit.osmocom.org/3899 which has failed in https://jenkins.osmocom.org/jenkins/job/OpenBSC-gerrit/2451/ and https://jenkins.osmocom.org/jenkins/job/OpenBSC-gerrit/2454/ I know Neels and others have spend already significant time in the past trying to resolve this - unsuccessfully. So I think the situation has reached a point where we should disable the vty tests, or at least the specific part of the vty tests that is known to break most frequently. I definitely want us to have *more* testing, not less. However, when the test itself is not stable yet - particularly after that much time - we cannot have that buggy test delay our development. I would vote for running those tests regularly (daily, every few hours, you name it), but not as part of the mandatory build verification for gerrit V+1.

osmo-gsm-tester modems

We have this idea of giving the same modem a persistent name on ofono, which would solve the symptoms, but it's curious why this happens. I had the watchdog script in place that power cycles the quad modem board and restarts ofono as soon as the modem names mismatch what we expect. But lynxis disabled it. The reasoning is that we won't catch ofono errors. That may be true; my idea was to be able automatically recover ofono without manual intervention. I guess it all depends on how closely you (lynxis) watch the gsm testers for failures? Because my focus is not particularly on ofono, and when I hit a broken situation and need to test things, I will restart ofono and rather not in-depth investigate the failure; in a dismissive way "come on ofono, do what I want now." What do you guys think about this? > I guess only /sierra_2 crashes because it's the first modem in the > resources.conf list and thus it is usually used in all tests (for instance, > tests which require only 1 modem), and probably some of the steps done in > one of those tests is crashing the modem. Something I thought about before: we could implement a kind of random or round robin to not always pick the first matching resources in the list. Advantage is that we would cycle through the hardware and force us to precisely formulate e.g. modem requirements. The disadvantage is that not every test is run exactly the same, adding complexity that may obscure analysis. i.e. to reproduce a run on a particular modem, we would have to somehow clamp that randomness, e.g. log a random seed at the start and allow passing in a random seed on the cmdline. ~N

OpenBSC and OsmocomBB
by Testphone Test 11 Sep '17

11 Sep '17

Dear List I am trying to run osmocomBB with motorola c118 with openbsc.I tried to get openbsc network on my phone it works well and I am able to register on openbsc network. But when i try to run osmocomBB with openBSC i am not able to get network. Also when i run rssi firmware on c118 phone i get network and its working fine. I am using default configuration file for OpenBSC and using NanoBTS with 1800Mhz support. Is there any configuration change is needed in openBSC ? <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> Virus-free. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

OsmoBTS after NITB split
by Max 09 Sep '17

09 Sep '17

Hi. The OsmoBTS build depends (unfortunately) on OpenBSC because it uses gsm_data_shared.h header. ATM this file is available in osmo-bsc and osmo-msc (maybe other split repos as well). Which is the "canonical" one from OsmoBTS point of view? Also, when would be the right time to move OsmoBTS' jenkins job to use one of the split repos instead of old OpenBSC? -- Max Suraev <msuraev(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Alt-Moabit 93 * 10559 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschaeftsfuehrer / Managing Director: Harald Welte
