The nanoBTS has a rather odd timing behavior. Jacob has spent hours this summer to trial/document/fix it in the MGCP code and this code is not getting close to working around the ip.access audio issues. If someobody still wants to use the nanoBTS then he should help to have the MGCP MGW use/share code with the rtp_proxy.c ----------------------------------------------------------------------- Summary of changes: openbsc/src/libtrau/rtp_proxy.c | 21 --------------------- 1 file changed, 21 deletions(-) hooks/post-receive -- The OpenBSC GSM Base Station Controller (+MSC/HLR/SGSN)

That is to say, the old revision is not a strict subset of the new revision. This situation occurs when you --force push a change and generate a repository containing something like this: * -- * -- B -- O -- O -- O (18d3450120796026837803177a9b39862effdcc3) \ N -- N -- N (3fb6fbddfd6c7c524d9718953e11d1253c176c03) When this happens we assume that you've already had alert emails for all of the O revisions, and so we here report only the revisions in the N branch from the common base, B. Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- http://cgit.osmocom.org/openbsc/commit/?id=3fb6fbddfd6c7c524d9718953e11d125… commit 3fb6fbddfd6c7c524d9718953e11d1253c176c03 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Tue Dec 23 14:24:16 2014 +0100 sgsn: Handle GSUP errors (WIP) Ticket: OW#????

This patch adds a timer based PING mechanism that regularly sends PING messages and forces a reconnect if a PONG message won't be received until the next PING message is scheduled. The current ping interval is 20s.

This means, that the client doesn't answer to PING and ID_GET and logs notices when receiving PONG or ID_ACK. At least the PING functionality (remotely originated PING) shall be supported. This patch extends gsup_client_read_cb by a call to ipaccess_bts_handle_ccm. Only when the return code is 0, the message is processed further and checked for an OSMO/GSUP message. ID_GET messages are answered by a dummy description, where only the unit_name is set to 'SGSN'.

In either case, the application gets informed about the connection state via the updown_cb. The 'up' parameter is only set, if poll/select consider the socket as writable. This patch handles both cases equally and fully relies on the updown_cb to adjust the gsupc obejct state.

The MS has probably sent several Attach Requests while the connection was down and will continue doing so. Therefore these stored messages could be dropped. This patch clears the queue before re-connecting and also extends gprs_gsup_client_send to return immediately, when the connection is not established instead of calling ipa_client_conn_send. Sponsored-by: On-Waves ehf http://cgit.osmocom.org/openbsc/commit/?id=877eaefa8b2f13758103eb77aeaa57db… commit 877eaefa8b2f13758103eb77aeaa57db4bb58ef4 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Thu Dec 18 15:00:29 2014 +0100 sgsn: Add automatic re-connect if the GSUP connection is down Currently the GSUP connection to a server is not restarted if the connection cannot be established or is terminated during operation. This commit adds a timer based connection mechanism, basically consisting of a timer callback that calls gsup_client_connect. The timer is eventually triggered (up == 0) or cleared (up != 0) by gsup_client_updown_cb. It adds calls to osmo_timer_del() to gsup_client_connect and gprs_gsup_client_destroy. The latter is now called instead of talloc_free in gprs_gsup_client_create on error to be on the safe side.

The same goes for RESUME in the state GMM_REGISTERED_NORMAL. This commit changes gprs_gmm_rx_suspend and gprs_gmm_rx_resume to not complain (and thus answer a NACK) when the MM context is either in GMM_REGISTERED_SUSPENDED or GMM_REGISTERED_NORMAL. Note that GSM 08.18, 7.4.1 and 7.5.1 only mention to send an NACK if the MS is not known. Even with this patch, the SGSN returns a NACK if either the MS is unknown _or_ the MM context ist not in one of the state GMM_REGISTERED_SUSPENDED and GMM_REGISTERED_NORMAL.

In addition they are named like libosmocore's TLV parser functions and do not have a proper name prefix. Since it is planned to use them for other protocols, they need to be globally accessible. This patch moves them to gprs_utils.c and renames them. The new names are: lv_shift -> gprs_shift_lv v_fixed_shift -> gprs_shift_v_fixed lv_shift -> gprs_shift_lv v_fixed_shift -> gprs_shift_v_fixed In the long term, these functions should be moved to libosmocore (and renamed again).

Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- http://cgit.osmocom.org/osmo-bts/commit/?id=2eb9812ec53fcaccf5623a1b7aad7fd… commit 2eb9812ec53fcaccf5623a1b7aad7fd6373552e5 Author: Holger Hans Peter Freyther <holger(a)moiji-mobile.com> Date: Tue Dec 23 11:47:28 2014 +0100 sysmobts: Create a calibration loop that will be run Continously run the calibration process.

The sysmobts-mgr code first needs to determine if the clock adjustment is necessary at all. This is done by first resetting the counters, then waiting, then asking for the diff and then applying the correction value. But the reference clock is only set by the application comand. Copy more code of l1if_rf_clock_info_reset to set the reference clock as value. This is leaving some todos inside the code that will be resolved as part of SYS#835.

The first step is to open (and re-open) the control connection to the BTS. As the connection is on localhost there should not be a computation overhead to always have the connection open. When connecting assume that the ASYNC connect worked directly as otherwise we get no notification of the failure. This looks like a "bug" of libosmo-abis that should check if the socket has been connected or not. http://cgit.osmocom.org/osmo-bts/commit/?id=1716cb479cfe1ddaa240e7ed1dc6a47… commit 1716cb479cfe1ddaa240e7ed1dc6a47f00bdc234 Author: Holger Hans Peter Freyther <holger(a)moiji-mobile.com> Date: Fri Dec 12 16:54:08 2014 +0100 msg: Generalize the message structure test This was taken out of LaF0rge's OML router branch and is now used by the extended calibration feature. ----------------------------------------------------------------------- Summary of changes: configure.ac | 1 + src/osmo-bts-sysmo/Makefile.am | 9 +- src/osmo-bts-sysmo/eeprom.c | 2 +- src/osmo-bts-sysmo/misc/sysmobts_eeprom.h | 2 +- src/osmo-bts-sysmo/misc/sysmobts_mgr.h | 29 +++- src/osmo-bts-sysmo/misc/sysmobts_mgr_2050.c | 20 +++ src/osmo-bts-sysmo/misc/sysmobts_mgr_calib.c | 189 ++++++++++++++++++++++++--- src/osmo-bts-sysmo/misc/sysmobts_mgr_temp.c | 70 ++++++++-- src/osmo-bts-sysmo/misc/sysmobts_mgr_vty.c | 122 ++++++++++++++++- src/osmo-bts-sysmo/misc/sysmobts_misc.h | 1 + src/osmo-bts-sysmo/misc/sysmobts_par.c | 36 ++++- src/osmo-bts-sysmo/misc/sysmobts_par.h | 2 + src/osmo-bts-sysmo/misc/sysmobts_util.c | 33 +++-- 13 files changed, 465 insertions(+), 51 deletions(-) hooks/post-receive -- Osmocom BTS-side code (Abis, scheduling, ...)

The same goes for RESUME in the state GMM_REGISTERED_NORMAL. This commit changes gprs_gmm_rx_suspend and gprs_gmm_rx_resume to not complain (and thus answer a NACK) when the MM context is either in GMM_REGISTERED_SUSPENDED or GMM_REGISTERED_NORMAL. Note that GSM 08.18, 7.4.1 and 7.5.1 only mention to send an NACK if the MS is not known. Even with this patch, the SGSN returns a NACK if either the MS is unknown _or_ the MM context ist not in one of the state GMM_REGISTERED_SUSPENDED and GMM_REGISTERED_NORMAL.

The current ping interval is 20s.

This means, that the client doesn't answer to PING and ID_GET and logs notices when receiving PONG or ID_ACK. At least the PING functionality (remotely originated PING) shall be supported. This patch extends gsup_client_read_cb by a call to ipaccess_bts_handle_ccm. Only when the return code is 0, the message is processed further and checked for an OSMO/GSUP message. ID_GET messages are answered by a dummy description, where only the unit_name is set to 'SGSN'.

In either case, the application gets informed about the connection state via the updown_cb. The 'up' parameter is only set, if poll/select consider the socket as writable. This patch handles both cases equally and fully relies on the updown_cb to adjust the gsupc obejct state.

The MS has probably sent several Attach Requests while the connection was down and will continue doing so. Therefore these stored messages could be dropped. This patch clears the queue before re-connecting and also extends gprs_gsup_client_send to return immediately, when the connection is not established instead of calling ipa_client_conn_send.

This commit adds a timer based connection mechanism, basically consisting of a timer callback that calls gsup_client_connect. The timer is eventually triggered (up == 0) or cleared (up != 0) by gsup_client_updown_cb. It adds calls to osmo_timer_del() to gsup_client_connect and gprs_gsup_client_destroy. The latter is now called instead of talloc_free in gprs_gsup_client_create on error to be on the safe side.

This patch replaces that flag by a global cfg.require_authentication flag that enables/disables the use of the Auth & Ciph procedure for every subscriber. The flag is set by the VTY, if and only if the authorization policy is 'remote'. The VTY command - update-subscriber imsi IMSI insert authenticate <0-1> is removed.

In addition they are named like libosmocore's TLV parser functions and do not have a proper name prefix. Since it is planned to use them for other protocols, they need to be globally accessible. This patch moves them to gprs_utils.c and renames them. The new names are: lv_shift -> gprs_shift_lv v_fixed_shift -> gprs_shift_v_fixed lv_shift -> gprs_shift_lv v_fixed_shift -> gprs_shift_v_fixed In the long term, these functions should be moved to libosmocore (and renamed again).
