2017-11-11osmo-bsc-sccplite: Implement incoming RESET procedureHarald Welte1-1/+1
In osmo-bsc-sccplite we so far didn't implement the inbound RESET procedure. We instead ignored any RESET message from the MSC. This commit adds support for RESET: We will destrpy any SCCP connections and acknowledge the RESET to the MSC. As osmo-msc is requiring the BSC to handle an inbound RESET procedure, this commit allows osmo-msc to properly initialize the A interface towards osmo-bsc-sccplite via a translating/routing osmo-stp. While we don't anticipate any new deployments of osmo-bsc-sccplite, making it interoperate with osmo-msc enables us to do more testing of osmo-bsc-sccplite.

2017-05-10src: use osmo_timer_setup()Pablo Neira Ayuso1-4/+2
Use new function available in libosmocore to set up timers. Compile tested only. Change-Id: Ibcfd915688e97d370a888888a83a7c95cbe16819
2017-02-24cosmetic: rename struct osmo_msc_data to bsc_msc_dataNeels Hofmeyr1-2/+2
With the OsmoMSC program coming up, the name osmo_msc_data becomes even more confusing than it already is. Clearly indicate it as libbsc's data of a remote MSC by prefixing with bsc_. Also, the Osmocom community has in the meantime agreed to have the osmo_ prefix only in libosmocore, to avoid naming conflicts in case things are moved there. So while renaming anyway, also drop the osmo_ prefix. Change-Id: I0dfbcb7d1a579211180f71319982820d8700afab

2016-12-02split subscr_con_allocate()/_free() in bsc_ and msc_Neels Hofmeyr1-2/+2
Rename current subscr_con_allocate() and subscr_con_free to bsc_*, and add two separate msc_subscr_con_allocate() and _free(). The msc_subscr_con_free() ignores all lchan members. In libbsc use bsc_*, in libmsc use msc_*. Change-Id: I3cf7c7cafdf4672ec7b26058bba8a77159855257 Future: there will be distinct subscr conns for libbsc and libmsc.
2016-12-02factor out gen of USSD notify and release complete to libosmocoreNeels Hofmeyr1-2/+2
Both libmsc and libbsc will need distinct gsm0480_send_ussdNotify() and gsm0480_send_releaseComplete() functions, since there will be distinct subscriber connection structs. Rename to msc_send_ussd_notify() and msc_send_ussd_release_complete(), and add the same in libbsc with bsc_ prefix in new file gsm_04_80_utils.c. In preparation of this patch, the message generation part of these functions has been added to libosmocore as gsm0480_create_ussd_notify() and gsm0480_create_ussd_release_complete(). Use these. Adjust all libmsc and libbsc callers according to use the msc_* or bsc_* implementation, respectively. Change-Id: I33a84e3c28576ced91d2ea24103123431f551173

2014-09-05bsc: Add a "IPA PING" to the SCCP CR messagesHolger Hans Peter Freyther1-3/+10
We want to reduce the background traffic and might set the ping interval to be in the range of minutes. But this means that if the TCP connection is frozen several "SCCP CR CM Service Requests" will be stuck in the send queue without ever being answered. I could have used the logic of not receiving the "SCCP CC" to close the connection but instead I am introducing an overload to schedule the ping as part of the normal SCCP connection establishment. The VTY write case has been manually verified, I have also looked at a single trace to see that the SCCP CR and the IPA PING is transfered in the same ethernet frame.
2013-11-15bsc: Use the right string for the notificationHolger Hans Peter Freyther1-1/+1
2013-09-11ussd: Send USSD on call setup on MSC errorsJacob Erlbeck1-7/+7
Send an USSD message to the mobile station requesting a connection for a call or a SMS when the link to the MSC is down or in the grace period. The messages can be set (and this feature activated) by setting bsc/missing-msc-text resp. msc/bsc-grace-text via the vty. The generation of both messages has been tested manually. Ticket: OW#957
2013-09-02bsc: Fix compiler warning about undeclare functionsHolger Hans Peter Freyther1-0/+1
Addresses: osmo_bsc_sccp.c:280:2: warning: implicit declaration of function ‘gsm0480_send_ussdNotify’ [-Wimplicit-function-declaration] osmo_bsc_sccp.c:281:2: warning: implicit declaration of function ‘gsm0480_send_releaseComplete’ [-Wimplicit-function-declaration]
2013-08-28bsc/ussd: Optionally send USSD message on MSC disconnectionJacob Erlbeck1-4/+26
Send an USSD message on each MS connection if the connection to the MSC has been lost. Add a vty config command 'bsc-msc-loss-txt' in 'config-msc' to set the notification string and to enable the feature. Ticket: OW#957
2013-01-28bsc: A BTS excluded from the RF lock should be allowed to make a connectionHolger Hans Peter Freyther1-4/+1
When introducing the exclude for the BTS lock the RF stayed up but all connections were immediately released. Optionally pass the BTS as second parameter and check the exclude bit. Tested-with: rf-lock-exclude/RFLockExcludeTest.st
2012-09-11bsc: Hand the msc_connection to the UDT handling, pass it to pagingHolger Hans Peter Freyther1-1/+1
Pass the osmo_msc_data to the paging sub system, change the code to pass the osmo_msc_data instead of network + bsc_msc_conn.
2012-09-11bsc: Select a MSC in a round-robin fashionHolger Hans Peter Freyther1-8/+5
Select a MSC, add it to the back of the list after we have selected it.
2012-09-11msc: Only kill connections belonging to the given MSCHolger Hans Peter Freyther1-2/+4
When a MSC connection drops, only kill the connections that belong to the given MSC and not all other connections.
2012-03-16bsc: Prepare to have multiple MSC connectionsHolger Hans Peter Freyther1-1/+6
We now have a list of MSCs but in the code we will try to access the MSC with the nr 0.
2012-03-16bsc: Use the right connection for outgoing packetsHolger Hans Peter Freyther1-2/+10
This is needed for simple UDT messages where we do not have a SCCP connection.
2012-03-16bsc: Move away from ->bsc.msc to use the selected MSCHolger Hans Peter Freyther1-4/+4
For multiple MSCs we should only have one place where the MSC is selected and the rest will extract it from somewhere.
2012-03-16bsc: Stop using net->bsc->msc and get the right msc from somewhere elseHolger Hans Peter Freyther1-4/+6
2012-03-16bsc: Create a osmo_bsc_data and embed osmo_msc_dataHolger Hans Peter Freyther1-6/+6
We want to have multiple MSCs but we also have some data that is only present on a per BSC basis. Right now the MSC data is not allocated with talloc, so we have some change in the talloc contexts.

2011-07-19bsc: Correct the cast for the signal dataHolger Hans Peter Freyther1-3/+3
There is a dedicated msc_signal_data cast the signal_data to this type and enjoy working connection closing on a per MSC base.

2011-03-23Fix build of bsc-nat and GPRS code after include path changeHarald Welte1-2/+2
The last patch changed the osmocore include paths, this fixes some build problems caused by it
2011-03-23src: use new library libosmogsm and new path to headers in libosmocorePablo Neira Ayuso1-3/+3
libosmogsm is a new library that is distributed in the libosmocore. Now, openbsc depends on it. This patch gets openbsc with this change. This patch also rewrites all include path to the new osmocom/[gsm|core] Signed-off-by: Pablo Neira Ayuso <pablo@gnumonks.org>
2011-03-03re-structure the OpenBSC directory layoutHarald Welte1-0/+288
The new structure divides the code into a number of libraries for the BSC core functionality, MSC core functionality, Abis transport, TRAU and other bits. This doesn't introduce any functional code change but simply moves around files and alters Makefile.am accordingly. Next step would be to disentangle a lot of the inter-library dependencies and make the individual bits of code more independent.
