OpenBSC operate FemtoCells?
by Bthomas 27 May '11

27 May '11

Dear OpenBSC lovers and developers! My questions is follow: 1. The OpenBSC software operate FemtoCell? (installed OpenBSC generate firmware to FemtoCell devices or operate FemtoCell devices? it is not clear to me) 2. If question nr1 is yes, you do not need any other hardware? (e.g. usrp device or BS11 or anything) 3. If question nr1 and nr2 both yes, then FemtoCell device and OpenBSC the combined use of mini private GSM network? I would like to deal with her hobby, and a better-cheaper-FemtoCell device access, such as a usrp device. Thank you for your answers! bthomyka from Hungary(EU) [ bthomas at mailbox dot hu ]

How does the phone know if it is roaming or not? When my phone camps to OpenBTS network it says it is roaming but in OpenBSC it doesn't. I wonder what makes such difference Sent from my iPhone

[PATCH 0/3] new VTY commands to enable IPA proxy
by pablo＠gnumonks.org 23 May '11

23 May '11

From: Pablo Neira Ayuso <pablo(a)gnumonks.org> Hi! This patchset adds new VTY commands that allows to route IPA flows. Patch 3/3 includes one feature that changes the current default behaviour of OpenBSC since you explicity have to make a "ipa setup" to enable OML and RSL links. If you like it, I can make a similar patch for HSL femto, so the only initial open socket is the one at port 4242 for telnet configuration. BTW, the original command syntax was proposed by Harald. Successfully tested bootstrapping the nanoBTS. See the patches for more details. Comments welcome!

fix missing all logging command option
by Pablo Neira Ayuso 19 May '11

19 May '11

Hi Holger, Thanks for fixing this, I missed it: http://cgit.osmocom.org/cgit/libosmocore/commit/?id=952a18ed19f531b82e26108… However, this fix is incomplete: /* This generates the logging command string for VTY. */ const char *log_vty_command_string(const struct log_info *info) { int len = 0, offset = 0, ret, i, rem; int size = strlen("logging level () ()") + 1; ^^ We also have to add `(all|' there.
