Log just as prominently to mark CM Service Accept.
Don't end a CM Service Request "lock" too indiscriminately. Trigger only on new
transactions that start.
The future perspective is to remember the preferred RAB Transport Layer Address
encoding for each 3G cell that is connected, so store per UE conn instead of
Add rab_assign_addr_enc member to ue_conn_ctx. Thus the iu_rab_act_cs() and
iu_rab_act_ps() functions no longer need the explicit use_x213_nsap argument.
Add include/openbsc/common.h in order to define the enum nsap_addr_enc, in a
separate file to be able to easily include it in all of libmsc, libiu and
gprs/* without creating include cycles.
Set the rab_assign_addr_enc when an MM ctx is created for iu, and whenever the
ue_conn_ctx for an Iu MM ctx is updated. This looks a bit clumsy so far, the
hope is that there will be a nice way to setup the ue_conn_ctx prior to that.
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.
Rename gsm48_cc_tx_call_proc() to gsm48_cc_tx_call_proc_and_assign() to mark
the place where the A-interface will send a BSSAP Assignment Request / where
the IuCS-interface will send a RAB Assignment Request.
Add function msc_call_assignment() to decide between A-iface and IuCS
assignment, to be implemented in subsequent commit.
Add libiu function to send a CommonID message down a UE connection,
iu_tx_common_id(); add also a corresponding stub to libiudummy for linking with
Add libmsc function msc_tx_common_id() to call the above. Add this mostly to
clearly indicate in msc_ifaces.h that libmsc is calling out of the MSC; also
to do conn->via_iface checking.
Call msc_tx_common_id() after ciphering is established, in
_gsm48_rx_mm_serv_req_sec_cb()'s GSM_SECURITY_SUCCEEDED case.
In osmo-nitb, libmsc would directly call the functions on the BSC level, not
always via the bsc_api. When separating libmsc from libbsc, some functions are
missing from the linkage.
Hence duplicate these functions to libmsc, add an msc_ prefix for clarity, also
add a _tx to gsm0808_cipher_mode():
* add msc_gsm0808_tx_cipher_mode() (dummy/stub)
* add msc_gsm48_tx_mm_serv_ack()
* add msc_gsm48_tx_mm_serv_rej()
Call these from libmsc instead of
Also add a comment relatd to msc_gsm0808_tx_cipher_mode() in two places.
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]").
