2017-02-23IuCS: rapidly release connectionsNeels Hofmeyr1-0/+3
Do the same as we do in 2G: release the connection as soon as nothing else is pending for a given subscriber. Before, osmo-cscn would wait for the UE "to get bored" and send an Iu release. But the CN should stay lean on connections. Also, 25.413[1] in section 7, 6th point states: "While the Iu release is managed from the CN, the RNC has the capability to request the release of all Iu connection resources from the corresponding Iu connection." So far we did not manage Iu release from osmo-cscn at all. Use the same mechanism we use in 2G: from msc_release_connection(), just before freeing the gsm_subscriber_conn, invoke a CN initiated Iu Release command to the UE. This works around OS#1816 ("USSD only works when IuCS is released", on nano3G), because the Iu conn is now released right after every signalling, so that typically no two requests will use the same conn. In iu.h/iu.c, add iu_tx_release(), absorbing almost all of the code from ranap_handle_co_iu_rel_req(). Add stub to db_test.c, necessary to build it without linking libiu.

2017-02-23IuCS: implement msc_call_assignment() for IuCSNeels Hofmeyr1-0/+11
Send IuCS RAB Activation upon MNCC_CALL_PROC_REQ. Implement function msc_call_assignment(): decide between sending A-iface BSSMAP Assignment Request or IuCS RAB Assignment Request. Implement iu_rab_act_cs() to send the IuCS RAB Assignment Request. The IP address and port of the MGCPGW sent in the RAB Assignment are still hardcoded. The A-interface extension is not implemented yet. Declare ranap_new_msg_rab_assign_voice() to avoid including ranap_msg_factory.h, which would require adding ASN1 CFLAGS to Makefile.am. The mgcpgw_client as well as some more osmo-iuh functions are now linked from libmsc, hence add some dummy stubs to libiudummy and db_test.c. Change-Id: Iaae51d1fbbfc28fad1c0b85e161d53d80a420a19
2016-07-09Make random MSISDN assignment optionalMax1-9/+21
Previously if subscriber was automatically created it got assigned random MSISDN number. Make it optional (defaulting to previous behavior) by adding following: * new optional no-extension argument for subscriber-create-on-demand vty command * db unit tests * vty test Note: using the db made with new code might result in subscribers with empty extension. Such subscribers cannot be deleted using old code. Make sure not to mix db versions or manually fix it by editing sqlite with external program.

2016-06-14Make random extension range configurableMax1-3/+3
Previously if subscriber was automatically created it got assigned random MSISDN number between 20000 and 49999. Make it configurable with new vty command "subscriber-create-on-demand random" and expand vty tests to check it. Change-Id: I040a1d227b0c7a1601dc7c33eccb0007941408a6 Related: OS#1658

2016-04-06subscr: Make db_create_subscriber fail on duplicatesHolger Hans Peter Freyther1-1/+5
The issue of db_create_subscriber updating an already existing subscr is that the same subscriber will then have two entries in the active subscribers list. In general this will break assumptions that a subscr can be compared by comparing the pointer. In the case of the VTY this was not an issue as the created subscr was immediately destroyed again but it is better to avoid this problem. Change the VTY command to find the subscriber and then call sync to have the updated time set. The side-effect is we will now have two queries for the subscriber. Once through subscr_get_by_imsi and once through db_create_subscriber. Change the db_create_subscriber to fail if a subscriber already exists, and add a testcase for this behavior and do not updated the 'updated' timestamp of an already existing subscriber. Add a testcase for this behavior. Related: OS Issue #1657

2016-03-17move to hex TMSI representationVadim Yanitskiy1-2/+2
In OpenBSC, we traditionally displayed a TMSI in its integer representation, which is quite unusual in the telecom world. A TMSI is normally printed as a series of 8 hex digits. This patch aligns OpenBSC with the telecom industry standard. Signed-off-by: Vadim Yanitskiy <axilirator@gmail.com>
2014-12-25db: Extend the test to mark a SMS as delivered and verify itHolger Hans Peter Freyther1-0/+7
Mark the SMS as delivered, then free it and try to get an undelivered SMS to that subscriber again and make sure it is failing.
2014-12-05msc: Add and use gsm_subscriber_groupJacob Erlbeck1-3/+7
Currently every subcriber object directly refers to the gsm_network which contains a flag shared by every related subscriber (keep_subscr). This adds a dependency on gsm_network even if only the function defined in gsm_subscriber_base.c are used. This patch adds a new struct gsm_subscriber_group which contains the keep_subscr flag and a back reference to the network object. The latter is not dereferenced in gsm_subscriber_base.c, so it can safely be set to NULL when only that part of the gsm_subscriber API is being used. It also changes that API to use gsm_subscriber_group instead of gsm_network parameters. Since there are some places where a pointer to the gsm_network is needed but where only a gsm_subscriber is available, a 'net' back pointer is added to the group struct, too. Nevertheless subscr group and network could be separated completely, but this is not the topic of this commit. Sponsored-by: On-Waves ehf

2011-02-11[BSC] Move the BTS-type specific code from bcs_init.c to bts_*.cHarald Welte1-2/+0
bsc_init.c was a big mess even only for two supported BTS models, so before adding more BTS types, this needs a cleanup. All the BTS specific code from bsc_init.c has now moved into bts_{siemens_bs11,ipaccess_nanobts}.c This has required that input_event() and nm_state_event() get both converted to proper libosmocore signals instead of referencing external symbols.

2011-01-01License change: We are now AGPLv3+ instead of GPLv2+Harald Welte1-5/+4
The reason for this is quite simple: We want to make sure anyone running a customized version of OpenBSC to operate a network will have to release all custom modifiations to the source code.

2009-09-28[tmsi] Make the tmsi a 4 octet numberHolger Hans Peter Freyther1-2/+2
tmsi is four octets long, there is no need to make it a string and then jump through hoops to convert it to a number. Keep the database using it as a string to benefit from the NULL handling of the db. Introduce the reserved tmsi which has all bits set to 1 according to GSM 03.03 ยง2.4 and start checking for it and make sure the db code will never allocate such a tmsi.
