Vadim Yanitskiy gerrit-no-reply at lists.osmocom.orgHello Stefan Sperling, Neels Hofmeyr, Harald Welte, Jenkins Builder,
I'd like you to reexamine a change. Please visit
https://gerrit.osmocom.org/11069
to look at the new patch set (#12).
Change subject: GSUP/SMS: introduce MO-/MT-FORWARD-SM messages
......................................................................
GSUP/SMS: introduce MO-/MT-FORWARD-SM messages
According to 3GPP TS 29.002, there are two services:
- MAP-MO-FORWARD-SHORT-MESSAGE (see 12.2),
- MAP-MT-FORWARD-SHORT-MESSAGE (see 12.9),
which are used to forward MO/MT short messages.
This change replicates both services as GSUP messages:
- OSMO_GSUP_MSGT_MO_FORWARD_SM_*,
- OSMO_GSUP_MSGT_MT_FORWARD_SM_*.
Please note, that only the 'must-have' IEs are introduced
by this change, in particular the following:
- OSMO_GSUP_SM_RP_MR_IE (see note below),
- OSMO_GSUP_SM_RP_DA_IE (see 7.6.8.1),
- OSMO_GSUP_SM_RP_OA_IE (see 7.6.8.2),
- OSMO_GSUP_SM_RP_UI_IE (see 7.6.8.4),
- OSMO_GSUP_SM_RP_MMS_IE (see 7.6.8.7),
- OSMO_GSUP_SM_RP_CAUSE_IE (see GSM TS 04.11, 8.2.5.4),
where both SM_RP_DA and SM_RP_OA IEs basically contain
a single nested TV of the following format:
- T: identity type (see 'osmo_gsup_sms_sm_rp_oda_t'),
- V: encoded identity itself (optional).
According to GSM TS 04.11, every single message on the SM-RL has
an unique message reference (see 8.2.3), that is used to link
an RP-ACK or RP-ERROR message to the associated (preceding)
RP-DATA or RP-SMMA message transfer attempt.
In case of TCAP/MAP, this message reference is being mapped to the
Invoke ID. But since GSUP has no 'Invoke ID' IE, and it is not
required for other applications (other than SMS), this change
introduces a special 'SM_RP_MR' IE that doesn't exist in MAP.
