[PATCH 1/4] sms: Kill the sms->sender and use addr/ton/npi throughout the code

by Holger Hans Peter Freyther

From: Holger Hans Peter Freyther <zecke(a)selfish.org> This is an incompatible database schema change. Store the type of the address in the database for both the sender and the receiver. Currently it is possible to use SMPP to store a SMS and the NPI and TON will be lost on the delivery of the SMS. The schema is changed to make the delivery always use the right NPI/TON. This patch is not ready for the master branch as there is no upgrade path for the HLR yet. --- openbsc/include/openbsc/gsm_data.h | 1 - openbsc/src/libmsc/db.c | 62 +++++++++++++++++++++++--------------- openbsc/src/libmsc/gsm_04_11.c | 9 ++---- openbsc/src/libmsc/smpp_openbsc.c | 5 ++- 4 files changed, 41 insertions(+), 36 deletions(-) diff --git a/openbsc/include/openbsc/gsm_data.h b/openbsc/include/openbsc/gsm_data.h index 1b4720f..e6a94ad 100644 --- a/openbsc/include/openbsc/gsm_data.h +++ b/openbsc/include/openbsc/gsm_data.h @@ -304,7 +304,6 @@ struct gsm_sms_addr { struct gsm_sms { unsigned long long id; - struct gsm_subscriber *sender; struct gsm_subscriber *receiver; struct gsm_sms_addr src, dst; enum gsm_sms_source_id source; diff --git a/openbsc/src/libmsc/db.c b/openbsc/src/libmsc/db.c index e26d3c5..39812c1 100644 --- a/openbsc/src/libmsc/db.c +++ b/openbsc/src/libmsc/db.c @@ -95,7 +95,6 @@ static char *create_stmts[] = { "id INTEGER PRIMARY KEY AUTOINCREMENT, " "created TIMESTAMP NOT NULL, " "sent TIMESTAMP, " - "sender_id INTEGER NOT NULL, " "receiver_id INTEGER NOT NULL, " "deliver_attempts INTEGER NOT NULL DEFAULT 0, " /* data directly copied/derived from SMS */ @@ -105,7 +104,12 @@ static char *create_stmts[] = { "protocol_id INTEGER NOT NULL, " "data_coding_scheme INTEGER NOT NULL, " "ud_hdr_ind INTEGER NOT NULL, " - "dest_addr TEXT, " + "src_addr TEXT NOT NULL, " + "src_ton INTEGER NOT NULL, " + "src_npi INTEGER NOT NULL, " + "dest_addr TEXT NOT NULL, " + "dest_ton INTEGER NOT NULL, " + "dest_npi INTEGER NOT NULL, " "user_data BLOB, " /* TP-UD */ /* additional data, interpreted from SMS */ "header BLOB, " /* UD Header */ @@ -1094,7 +1098,7 @@ int db_subscriber_assoc_imei(struct gsm_subscriber *subscriber, char imei[GSM_IM int db_sms_store(struct gsm_sms *sms) { dbi_result result; - char *q_text, *q_daddr; + char *q_text, *q_daddr, *q_saddr; unsigned char *q_udata; char *validity_timestamp = "2222-2-2"; @@ -1102,25 +1106,35 @@ int db_sms_store(struct gsm_sms *sms) dbi_conn_quote_string_copy(conn, (char *)sms->text, &q_text); dbi_conn_quote_string_copy(conn, (char *)sms->dst.addr, &q_daddr); + dbi_conn_quote_string_copy(conn, (char *)sms->src.addr, &q_saddr); dbi_conn_quote_binary_copy(conn, sms->user_data, sms->user_data_len, &q_udata); + /* FIXME: correct validity period */ result = dbi_conn_queryf(conn, "INSERT INTO SMS " - "(created, sender_id, receiver_id, valid_until, " + "(created, receiver_id, valid_until, " "reply_path_req, status_rep_req, protocol_id, " - "data_coding_scheme, ud_hdr_ind, dest_addr, " - "user_data, text) VALUES " - "(datetime('now'), %llu, %llu, %u, " - "%u, %u, %u, %u, %u, %s, %s, %s)", - sms->sender->id, + "data_coding_scheme, ud_hdr_ind, " + "user_data, text, " + "dest_addr, dest_ton, dest_npi, " + "src_addr, src_ton, src_npi) VALUES " + "(datetime('now'), %llu, %u, " + "%u, %u, %u, " + "%u, %u, " + "%s, %s, " + "%s, %u, %u, " + "%s, %u, %u)", sms->receiver ?

[PATCH] Use generic osmocom auth api

by ☎

Hi. Attached is a small patch which replaces direct call to comp128 from libosmocore to auth api call. This will help to remove comp128 from libosmocore public api and to use other auth functions in openbsc in future. -- best regards, Max, http://fairwaves.ru

Re: Support for binary SMS (GSM 03.48)

by Robert Light

Hi, I am also interested in being able to send SMS messages. Harald, the question is interesting, as I not only want to send "normal" messages but also "special" messages, like silent SMS, or messages formatted with ie SharpSMS. https://github.com/pbansky/SharpSMS I know that there are applications for mobile devices allowing to format these kind of SMS messages but this can be done much easier if we could do it from a PC. I am also interested in how can it be done with OpenBSC and OpenBTS.

Hi all, Prevent crash introduced in the a9fae1ae commit. Call "show network" in the NITB VTY without any BTS connected to reproduce the crash. Before it was stored in a local variable, but accessed from a net structure in the msc_signal_handler(). -- Regards, Alexander Chemeris. CEO, Fairwaves, Inc. / ООО УмРадио https://fairwaves.co

Support for binary SMS (GSM 03.48)

by George News

Hi all, ¿Is it possible to use the OpenBSC system to send binary SMS? If yes how? and if not could you please point me on how to start the development? I know using the monitor app with the motorola phone is possible to send sms and make calls. Now I want to send binary SMS (03.48). TA. Jorge

[PATCH 1/8] agch: Recalculate length limit of AGCH queue

by Jacob Erlbeck

This patch adds a function bts_update_agch_max_queue_length() to compute a limit of the AGCH queue. This is based on the idea, that the AGCH queue has a limited drain rate and that CHANNEL REQUESTs must be answered within a certain time frame, given by the minimum value of T3126 (see GSM 04.08). When the AGCH queue reaches that limit, the last message would be delivered in time if there were no other delays involved (which is not the case). The calculation is based on the ratio of the number RACH slots and CCCH blocks per time: Lmax = (T + 2*S) / R_RACH * R_CCCH where T3126_min = (T + 2*S) / R_RACH R_RACH is the RACH slot rate (e.g. RACHs per multiframe) R_CCCH is the CCCH block rate (same time base like R_RACH) The value depends control_channel_desc.ccch_conf and rach_control.tx_integer (both from SYSINFO_TYPE_3) and should therefore by called at least each time after one of these is changed. For this reason, a signal callback is registered under SS_GLOBAL/S_NEW_SYSINFO which invokes bts_update_agch_max_queue_length().
