2021-01-14hodec2: to balance congestion, use overload percentNeels Hofmeyr1-3/+5
For balancing load across congested cells and across congested TCH/* kinds, instead of comparing the number of lchans above the configured congestion threshold, compare the percent of lchans of overload. In short, using a percentage prevents cells with less min-free-slots to fill up 100% while neighbor cells still may have several free lchans available. An obvious example of why this is desirable is illustrated by test_balance_congestion_by_percentage.ho_vty: Cell A has min-free-slots 2, and has all slots occupied. Cell B has min-free-slots 4, and has 2 slots remaining free. If we count congested lchans as in current master: cell A has a congestion count of 2: two more lchans in use than "allowed". If we move one lchan over to cell B, it ends up with a congestion count of 3, which is worse than 2. So when counting lchans, we decide that cell A should remain full. Instead, when comparing percentage of remaining lchans, we would see that cell A is loaded 100% above congestion (2 of 2 remaining lchans in use), but when moving one lchan to cell B, that would only be 75% loaded above its treshold (3 of 4 remaining lchans in use). So a percentage comparison would cause a handover to cell B. Related: SYS#5259 Change-Id: I55234c6c99eb02ceee52be0d7388bea14304930f
2021-01-13Introduce Neighbor Resolution ServicePau Espin Pedrol1-1/+100
This new CTRL interface allows users of this BSC (such as attached PCU) to gather neighbor information. This interface is needed for PCU to translate ARFCN+BSIC keys provided by MS in the Um side into CGI + RAC keys used to identify target cells in RIM procedures against SGSNs on the Gb interface. This patch extends the already existing neighbor information storage in the VTY by allowing storage of CGI + RAC (RAC couldn't be stored beforehand).

2020-09-18clean up timer definitions: introduce groups, move some T to XNeels Hofmeyr1-1/+1
Backwards compatibly, introduce timer groups in OsmoBSC, and move some non-specified T timers to new X timers: T993111 -> X3111 T993210 -> X3210 T999 -> X4 Why X4? because there already is an X3 used elsewhere in Osmocom, and I find it less confusing if X-numbers don't repeat across programs. See https://osmocom.org/projects/cellular-infrastructure/wiki/List_of_Timer_numbers Drop unused timers from g_mgw_tdefs. Only X2427 has an actual effect. (libosmo-mgcp-client recently moved T2427001 to X2427.) Put libosmo-mgcp-client related timers to the 'mgw' group, like in osmo-msc. This makes the MGCP timeout configurable for the first time. Keep previous timer commands as DEFUN_HIDDEN, and also translate the moved T timers to X timers on-the-fly. All previous VTY commands still work, and new 'timer [(net|mgw)] ...' commands are added. timer.vty shows this. Remove the "_OPTIONAL" from the legacy "timer" and "show timer" commands, so that they don't ambiguously overload the new "timer [(net|mgw)] ..." commands.

2020-09-09lchan_rtp_fsm: Deferr IPACC MDCX after BTS side MGCP MDCXPau Espin Pedrol2-7/+10
This is needed to be able to force MGW to provide an IPv4 address during MDCX, since IPACC protocol on the BTS side only supports IPv4, but one may need IPv6 side at the same time on the core side. By moving the IPACC MDCX request to a later step, the BSC gains knowledge of the local address on each side (BTS, MGW), and if they don't match (ie. BTS uses IPv4 and MGW uses IPv6), it can then get MGW to offer an IPv4 address during MGCP MDCX containing the BTS IPv4 address. At that point, the MGW can see the mismatch and provide an IPv4 address in the MGCP MDCX ACK, which can then finally be communicated to the BTS during IPACC MDCX phase. Previous order: BSC -> MGW: CRCX BSC <- MGW: CRCX ACK (get MGW local IP addr) BSC -> BTS: IPACC CRCX BSC <- BTS: IPACC CRCX ACK (get BTS local IP addr) BSC -> BTS: IPACC MDCX (set MGW IP addr) BSC <- BTS: IPACC MDCX ACK BSC -> MGW: MDCX (set BTS IP addr) BSC <- MGW: MDCX ACK New order: BSC -> MGW: CRCX BSC <- MGW: CRCX ACK (get MGCP local IPv6 addr) BSC -> BTS: IPACC CRCX BSC <- BTS: IPACC CRCX ACK (get BTS local IPv4 addr) BSC -> MGW: MDCX (set BTS IPv4 addr) BSC <- MGW: MDCX ACK (here MGW changes its local addr to IPv4) BSC -> BTS: IPACC MDCX (set MGW IPv4 addr) BSC <- BTS: IPACC MDCX ACK Change-Id: I4de5ea5c94c1482c9cb0b6386997a942edc60e32

2020-05-29drop all BSC originated USSD notification featuresNeels Hofmeyr1-7/+0
The BSC is the wrong network component to originate USSD messaging, as can be seen in the hacks in the USSD code: for example, the BSC would send a CM Service Accept message as if an MSC had accepted the connection, dispatch a USSD and directly send some RR release message (without proper tear down messaging like the lchan_fsm does these days). This made sense in the osmo-nitb world, but by now we are aiming for solid 3GPP compliance. The BSC shall not originate USSD messages. Deprecate all VTY and CTRL commands related to USSD: VTY [no] bsc-welcome-text [no] bsc-msc-lost-text [no] bsc-grace-text [no] missing-msc-text (the commands with 'no' are ignored, without 'no' lead to an error) CTRL ussd-notify-v1 Drop (already unused) ussd.h. Drop gsm_04_80.h, gsm_04_80_utils.c, and all calling code. Drop "RF grace" notification, where osmo-bsc was able to notify active subscribers that the RF was being turned off.

2020-04-14vty: clarify EGPRS Packet Channel Request message supportVadim Yanitskiy1-4/+9
According to 3GPP TS 44.060, section 12.24, GPRS Cell Options IE contains two parameters related to 11 bit Access Burst support: - ACCESS_BURST_TYPE - whether the 8 or 11 bit format shall be used in the PACKET CHANNEL REQUEST message, the PTCCH/U block, PACKET CONTROL ACKNOWLEDGMENT and the PS HANDOVER ACCESS messages on the PRACH (if present). - EGPRS_PACKET_CHANNEL_REQUEST - whether EGPRS capable MSs shall use EGPRS PACKET CHANNEL REQUEST message for Uplink TBF establishment on the RACH or on the PRACH (if present). The VTY option 'gprs 11bit_rach_support_for_egprs' actually controls the second parameter - EGPRS_PACKET_CHANNEL_REQUEST, though it may be hard to understand this from its name and description. This patch is actually a group of tightly related changes: - deprecate 'gprs 11bit_rach_support_for_egprs (0|1)': - update its description to avoid any possible confusion, - print a warning if it's used in non-EGPRS mode, - print a warning if it's still used; - introduce '[no] gprs egprs-packet-channel-request': - ensure that it can only set / printed in the EGPRS mode; - take a chance to clean-up / rename the related struct members: - 'supports_egprs_11bit_rach' -> bool 'egprs_pkt_chan_request', - remove 'supports_egprs_11bit_rach' from 'gprs_cell_options' because we already have 'ext_info.use_egprs_p_ch_req' there.
