2017-03-16libmgcp: add mgcpgw client APINeels Hofmeyr1-0/+1
Add an API to send MGCP messages to an MGCP GW, from the perspective of an MSC instructing the GW to setup RTP streams. Rationale: the mgcp_protocol.h is mostly for the MGCP GW itself, other implementations forward incoming MGCP messages. So a simpler approach for an MGCP GW client is useful. Add general VTY commands that can be used to configure mgcpgw_client. osmo-msc is going to use this to route RTP streams (for 3G at first). Change-Id: I6fe365c4c89207f2172943cc456b508a207b1135

2017-03-16Prepare entry/exit point for MSC -> BSC and MSC -> RNC communication.Neels Hofmeyr1-0/+1
Add msc_ifaces.[hc], a_iface.c, with a general msc_tx_dtap() to redirect to different interfaces depending on the actual subscriber connection. While iu_tx() is going to be functional fairly soon, the a_tx() is going to be just a dummy for some time (see comment). Add Iu specific fields in gsm_subscriber_connection: the UE connection pointer and an indicator for the Integrity Protection status on Iu (to be fully implemented in later commits). Add lac member to gsm_subscriber_connection, to allow decoupling from bts->location_area_code. The conn->lac will actually be set in iu.c in an upcoming commit ("add iucs.[hc]").

2017-03-16Add libvlr implementationHarald Welte1-0/+1
Original libvlr code is by Harald Welte <laforge@gnumonks.org>, polished and tweaked by Neels Hofmeyr <nhofmeyr@sysmocom.de>. This is a long series of development collapsed in one patch. The original history may still be available as branch neels/vlr_orig. Related: OS#1592 Change-Id: I3f75de5f0cc2ff77f276fd39832dd3621309c4b9
2017-03-08add struct bsc_subscr, separating libbsc from gsm_subscriberNeels Hofmeyr1-0/+1
In a future commit, gsm_subscriber will be replaced by vlr_subscr, and it will not make sense to use vlr_subscr in libbsc. Thus we need a dedicated BSC subscriber: struct bsc_subscr. Add rf_policy arg to bsc_grace_paging_request() because the bsc_subscr will no longer have a backpointer to gsm_network (used to be via subscr->group). Create a separate logging filter for the new BSC subscriber. The implementation of adjusting the filter context is added in libbsc to not introduce bsc_subscr_get/_put() dependencies to libcommon. During Paging Response, fetch a bsc_subscr from the mobile identity, like we do for the gsm_subscriber. It looks like a duplication now, but will make sense for the VLR as well as for future MSC split patches. Naming: it was requested to not name the new struct bsc_sub, because 'sub' is too ambiguous. At the same time it would be fine to have 'bsc_sub_' as function prefix. Instead of struct bsc_subscriber and bsc_sub_ prefix, I decided to match both up as struct bsc_subscr and bsc_subscr_ function prefix. It's fast to type, relatively short, unambiguous, and the naming is consistent. Add bsc_subscr unit test. Related: OS#1592, OS#1594 Change-Id: Ia61cc00e8bb186b976939a4fc8f7cf9ce6aa3d8e
2017-02-25add struct gprs_subscr, separating gprs from gsm_subscriberNeels Hofmeyr1-0/+1
Prepare for replacing gsm_subscriber with vlr_subscriber. vlr_subscriber will not make sense to be used in gprs, so have a dedicated GPRS subscriber struct. (Could change if the gprs code were to use libvlr; is currently independent). Related: OS#1592 Change-Id: Ia8b391ee009c8545763cba04505be3947835120e
2017-02-24cosmetic: rename osmo_msc_data.h to bsc_msc_data.hNeels Hofmeyr1-1/+1
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: I13554563ce9289de126ba0d4cf329bafcda35607

This is in preparation for moving gsup to libcommon, which is in turn preparation for libvlr. Related: OS#1592 Change-Id: I9c95d00f1a9420887a44c938b1d0ee3e20586f4c
2016-11-24move to libcommon-cs: net init 2: move bsc_network_init decl to new .hNeels Hofmeyr1-0/+1
bsc_network_init() is more fit to live in a BSC specific header, move it to new common_bsc.h. It will probably also absorb the BSC-specific part of gsm_network in the future. Adjust header includes across the board. Particularly, fix abis_nm.h by explicitly including gsm_data.h: it so far relied on other headers to do that, which now is no longer always given.

2016-11-01OML: Improve OML attribute handlingPhilipp1-0/+1
the OML attribute tables are hardcoded. To set variable parameters, the hardcoded data structure (tlv) is patched on byte level during runtime. This patch replaces this mechanism. - Replace hardcoded OML attribute tables with dynamically generated TLV structures. - Add unit tests to check if the OML attribute tables are generated correctly - Put OML attribute table generator code in a separate file: bts_ipaccess_nanobts_omlattr.c Change-Id: Ibeb34a84912d6cf695f553a34c69320fca7d08fa

2016-09-24SNDCP: add SNDCP-XID encoder/decoder and unit testPhilipp1-0/+1
The SNDCP-XID (or layer-3 xid) is used to exchange layer-3 parameters such as compression. The encoder encodes a bytestream that is then sent as regular XID field from LLC. We will need the SNDCP-XID to negotiate the parameters for our upcomming GPRS data and header compression features Change-Id: If2d63fe2550864cafef3156b1dc0629037c49c1e

2015-11-16Add GTP hub initial code base.Neels Hofmeyr1-0/+1
First steps towards a new GTP hub. The aim is to mux GTP connections, so that multiple SGSN <--> GGSN links can pass through a single point. Background: allow having more than one SGSN, possibly in various remote locations. The recent addition of OAP to GSUP is related to the same background idea. (This is a collapsed patch of various changes that do not make sense to review in chronological order anymore, since a lot of it has thorougly transmorphed after it was first committed.)

2015-11-02libcommon: soak up three static functions.Neels Hofmeyr1-1/+1
Add new kitchen sink openbsc/utils.h and libcommon/utils.c to make three so far static functions public (so I can use them in the upcoming OAP code). A place to put them could have been the gprs_utils.h, but all general functions in there have a gprs_ prefix, and todo markings to move them away. All other libcommon headers are too specific, so I opened up this kitchen sink header. Replace the implementation of encode_big_endian() with a call to osmo_store64be_ext(). See comments. Apply the change in Makefiles and C files.
2015-05-03filter: Move the method definition to the filter moduleHolger Hans Peter Freyther1-1/+1
Move the filter methods to the filter module. This is still only usable for the NAT and the _dt/_cr filter routines need to move back to the bsc_nat in the long run.
2015-03-22rtp: Use osmocom/netif/rtp.h for the rtp structure definitionHolger Hans Peter Freyther1-1/+1

2015-01-01Initial support for export + curses-visualization of measurementsHarald Welte1-1/+1
This extends osmo_nitb to offer a UDP feed of real-time measurement reports, which can be used by (a variety of) external tools for visualization or other processing. We also add a small ncurses based tool (meas_vis) which shows a baragraph display of the last few mobile stations that were active, indicating their uplink/downlink receive level and quality. <WARNING> This sends non-portable structures like gsm_meas_rep over UDP and assumes the receiver has identical alignment and endianness! Before this feature is merged, it either needs to be converted to a unix domain socket (but they don't do multicast, which would be nice) or the wire format needs to change into something portable with defined alignment and encoding </WARNING>

2014-07-07rtp: Share the rtp header between the proxy and the mgcp codeHolger Hans Peter Freyther1-1/+1
2014-06-05mgcp: Move transcoding to libmgcpJacob Erlbeck1-1/+1
This patch moves the files relevant to transcoding from src/osmo-bsc_mgcp to src/libmgcp and src/include/openbsc. Makefiles and include directives are being updated accordingly. Sponsored-by: On-Waves ehf
2014-05-22mgcp: add voice muxer supportPablo Neira Ayuso1-1/+2
This patch adds the voice muxer. You can use this to batch RTP traffic to reduce bandwidth comsuption. Basically, osmux transforms RTP flows to a compact batch format, that is later on decompacted to its original form. Port UDP/1984 is used for the muxer traffic between osmo-bsc_nat and osmo-bsc_mgcp (in the BSC side). This feature depends on libosmo-netif, which contains the osmux core support. Osmux is requested on-demand via the MGCP CRCX/MDCX messages (using the vendor-specific extension X-Osmux: on) coming from the BSC-NAT, so you can selectively enable osmux per BSC from one the bsc-nat.cfg file, so we have a centralized point to enable/disable osmux. First thing you need to do is to accept requests to use Osmux, this can be done from VTY interface of osmo-bsc_nat and osmo-bsc_mgcp by adding the following line: mgcp ... osmux on osmux batch-factor 4 This just initializes the osmux engine. You still have to specify what BSC uses osmux from osmo-bsc_nat configuration file: ... bsc 1 osmux on bsc 2 ... bsc 3 osmux on In this case, bsc 1 and 3 should use osmux if possible, bsc 2 does not have osmux enabled. Thus, you can selectively enable osmux depending on the BSC, and we have a centralized point for configuration from the bsc-nat to enable osmux on demand, as suggested by Holger. At this moment, this patch contains heavy debug logging for each RTP packet that can be removed later to save cycles. The RTP ssrc/seqnum/timestamp is randomly allocated for each MDCX that is received to configure an endpoint.
2013-09-19nat: Fix make distcheck for the natHolger Hans Peter Freyther1-1/+1

2013-07-31nat: Introduce a prefix lookup tree (trie) for number rewritingHolger Hans Peter Freyther1-1/+1
* It is a trie. The max depth of the trie is the length of the longest prefix. The lookup is O(lookuped_prefix), but as the prefix length is limited, the lookup time is constant. * Each node can hold the entire prefix, has place for the rewrite rule with up to three digits. * A trie with 20k entries will take about 3MB ram. * Filling the trie 100 times takes ~800ms on my i7 laptop * 10.000.000 lookups take 315ms.. (for the same prefix). * 93/99 lines are tested, 6/6 functions are tested, 49 of 54 branches are tested. Only memory allocation failures are not covered * A late addition is to handle the '+' sign and to increase the number of chars in the rewrite prefix. The timing/line coverage has not been updated after this change.
2012-10-22si: Partially implement the range encoding for the SI.Holger Hans Peter Freyther1-1/+2
I saw the old copy of the "Appendix J" code too late and I have discovered some quirks and I am more familar with my implementation. Most noticable 'w' only needs to be as big as the input arfcn but requires the 'w' to be initialized. The power_of_2 implementation differs as well (mine matches the output of wirehsark). The f0 could be chosen in a better way but right now picking the lower bound is the easiest. It is not clear if to use modulo if the range is chosen in the middle. This can be improved in the future. Right now I have no bit fiddling for range128, 256 and 1024 as I was running out of time.
