2017-05-28bsc_vty: Add command to manually issue IPAC MDCXHarald Welte1-1/+31
Using this command, one can modify the RTP stream associated with a given logical channel and (re)direct it to a specified IP:Port. Change-Id: I63e03b932038a4e2f6d51c5541b52e4a42df27bf
2017-05-27bsc_vty.c: Add command for manual [de]actiovation of logical channelsHarald Welte1-0/+119
Sometimes it is useful to manually activate (or decativate) a given logical channel from the VTY. Doing this on the BSC (rather than the BTS) ensures that the BSC knows that this timeslot / channel is allocated and there is no risk to have clashes between the BSC "owning" the resources and the BTS allocating some by itself.

2017-05-27bsc_vty.c: Further simplify vty_get_ts()Harald Welte1-6/+7
We can also move the string-to-numeric conversion inside vty_get_ts() to reduce the amount of work required in the caller. Change-Id: I2a74ed06e90e39d39f53fff39bb96df172728c0e
2017-05-27bsc_vty: Factor vty_get_ts() out of pdch_act_cmd()Harald Welte1-14/+26
Resolving a timeslot based on its numeric identities is a generally useful function, so lets' factor that out. Change-Id: Id2570232f82542487a1133be7efb1dc1eb3029a8
2017-05-27bsc_api.c: Documentation for handle_mr_config()Harald Welte1-2/+13

2017-05-27costmetic: Document gsm48_multirate_config() + const-ify inputHarald Welte1-1/+6
We generally use const pointers for input arguments. Also, document input/output arguments of function and add spec reference. Change-Id: I2532cde69a18e3b021f7371e68f67a28a43d8b5f

2017-05-25pcu_sock: Fix broken paging commandPhilipp Maier1-7/+20
The pcu sends us an already made up MAC-Block that contains the paging request. pcu_sock.c is parsing this paging request wrongly and fails silently, which results into a dropping of the request. This commit fixes the parsing problems. Change-Id: Iefef08123bdc351afd8287d3f27ebf0ae58a6e7d
2017-05-25pcu_sock: Forward imm.ass PCU originated messagesPhilipp Maier2-0/+38
The PCU sends imm.ass messages in response to a rach request. Those messages need to be forwarded to RSL in order to get them send. This commit introduces the required functionality for that Change-Id: Ice099c4ed7008200ed179e581aba1899c6c29455
2017-05-25pcu_sock: implement direct tlli on AGCHAlexander Couzens1-0/+31
Ericsson allows to attach a reference to immediate assignments. A confirmation of the transmission is then sent back, but only containing the reference, not the whole RLC packet. Change-Id: I945f49e62e2a74a7906e2d49940927773edd04a9
2017-05-25pcu_sock: pcu_tx_info_ind allow to use TRX not starting from 0Alexander Couzens1-1/+1
It would prevent using only e.g. TRX 1 when TRX 0 is disabled. Change-Id: I68dc5e837bd2a3602f7875063c85da4082196274
2017-05-25pcu_sock: set flag PCU_IF_FLAG_SYSMO by setting pcu_direct = 1Alexander Couzens1-1/+1
The use of PCU_IF_FLAG_SYSMO enable the PCU to use DIRECT_PHY code path. Change-Id: I1f5407264fc4f209456ffcb73d7853ff315aab86
2017-05-25pcu_sock: Send non-NULL hLayer1 to PCUHarald Welte1-0/+1
The BSC-located PCU case looks to the PCU like a BTS-located PCU with "direct PHY" access, i.e. the data related primitives are communicated from the PCU directly towards the TRAU Frames or whatever transport method is used between CCU and PCU. In order to make the PCU believe that, we need to pass in a 'layer 1 handle'. As we don't use it, we can just pass any non-zero value and be happy.

2017-05-17Get basic BTS attributesMax2-0/+77
Request BTS attributes via OML on connection and parse the response: request/parse incoming response as sw-config. Note: only basic BTS-wide KV attributes wrapped in sw-config are supported for now. Change-Id: I589be51daca0cb9e1f3473b93e910e46b06e23ae Related: OS#1614
2017-05-15SI2quater: fix EARFCN inclusion checkMax2-3/+7
Previously only the existance of bts->si_common.si2quater_neigh_list was checked but not the actual number of EARFCNs in it. Fix it by using si2q_earfcn_count() and adjust tests accordingly. While at it - reformat tests to include extra information. The correctness was checked manually by inspecting GSMTAP output. Change-Id: Ic4fb2a9e870db66cac58b1e8d113587b30d64ce2 Related: RT#8792

2017-04-28Prepare for extended SI2quater supportMax3-55/+48
Supporting SI2quater as per 3GPP TS 44.018 will require chnages to the way System Information is stored because it uses 1:n instead of 1:1 mapping between SI type and generated SI content. This should not affect other SI types though. To facilitate this transition: * convert the code to always use GSM_BTS_SI helper instead of accessing buffer directly * make helper more robust by adding extra parenthesis * add similar helper for gsm_lchan * add function estimating number of SI2quater message to hold configured number of (U|E)ARFCNs * add SI2q index/count fields and pass them to rest_octets generator explicitly * internalize buffer access in generate_si* functions Change-Id: I74e4e3cb86364cec869a1472a41b4a95af0d50dd Related: RT#8792

2017-03-16Don't drop OML links for Get Attributes NACKMax1-10/+10
Previously any OML NACK message will result in BSC dropping OML link to BTS which makes it impossible to use optional OML messages which might be unsupported by BTS.

2017-03-15gprs: fix T3186 encoding in Sysinfo 13Philipp Maier1-1/+7
The timer T3186, which is described in 3GPP TS 44.060, is using 3 bits of the si13 mac block. This requires special encoding. In the case of T3186, the value is encoded by the formula: bits = t/500-1. Our implementation uses the formula bits=t/500, which is incorrect. Change-Id: Ifd340c536cff2d1c4b1b3677a358ea95438801eb
2017-03-15libbsc: add chreq type for CHREQ_T_PDCH_ONE_PHASE & CHREQ_T_PDCH_TWO_PHASEAlexander Couzens1-2/+14

2017-03-08add struct bsc_subscr, separating libbsc from gsm_subscriberNeels Hofmeyr6-54/+239
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
2017-03-02subscriber conn: add indicator for originating RANNeels Hofmeyr1-0/+1
Add via_ran to gsm_subscriber_connection to indicate whether a conn is coming in via 2G/GERAN/A-Interface or 3G/UTRAN/Iu-Interface. Prepares for Iu, but also for libvlr to decide between GSM or UMTS Auth. Until actual Iu support is merged to master, this indicator will aid VLR unit testing. At some point we may also add RAN_GERAN_IU; it's not on the agenda yet, but to clearly distinguish the names if we want to add it, explicitly name the ones we have RAN_GERAN_A and RAN_UTRAN_IU.

2017-02-24cosmetic: rename osmo_msc_data.h to bsc_msc_data.hNeels Hofmeyr4-4/+4
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
2017-02-23logging fixup: shorter names for LOGGING_FILTER_* and LOGGING_CTX_*Neels Hofmeyr2-5/+5
In libosmocore, my patch was merged to master a bit too soon. To accomodate the request for naming that matches the general "LOG" prefix instead of "LOGGING", a fixup was committed to libosmocore.
