The Signalling Field Element Coding list defined in 3.2.3 is used in "Old BSS to New BSS Information" and "New BSS to old BSS Information" IEs. However, the former IE (Old->New Info) defines 2 extra Field Elements in 3.2.2.58 (3GPP TS 48.008 version 16.0.0 Release 16) not present in 3.2.3.

Libosmocore currently does not offer any structs to encode and decode the l1 information on RSL level and the sacch l1 header on the air interface level. Both structs are identical but the field order in the first octet is reversed. Change-Id: I23c1890b89d5a0574eb05dace9f64cc59d6f6df7
2021-02-13gsm: Fix bitfield order in dtap_headerPau Espin Pedrol1-3/+3
This bitfield was added later and all osmocom code still uses the old field contain 1 byte "link_id". There's only one known user of the new bitfield which only uses it to log the SAPI name in osmocom, so no logical breakage is expected with this change (other than fixing a log line). While at it, fix a typo in comment describing related enum. Related: SYS#4909 Fixes: 392f607f2d42eb2839ccfc4c1b9e2c7cfaf3bcc2 Change-Id: I84866f03ee642aa7f1da273c93a16a38234cfa67

This structure is needed in order to identify a given cell within the BSS during RIM transactions. The naming was made up by myself since I couldn't find any naming reference for this kind of data (RAI + CI). Since LAI + CI = CGI, then RAI + CI = CGI-PS osmo_rai_name2 family of functions get a "2" suffix due to already existing functions handling struct struct gprs_ra_id in gsm48.h Change-Id: If48f412c32e8e5a3e604a78d12b74787a4786374

2020-11-12gsm_04_08: add parser for Mobile Station Classmark 3Philipp Maier1-0/+169
3GPP TS 24.008 section 10.5.1.7 describes a Mobile Station Classmark 3 IE, which is encoded as CSN.1 struct. This means that it can not be parsed by just casting a memory location to a struct pointer, so lets add a parser to parse the CM3 IE. This is fixed version of Ic8b2bfd00330235f5bed00771e421588abfaac1f, which got reverted because it used the keyword "class" as struct member, which lead into problems with c++ builds. This is now fixed. Change-Id: Id8732551b33616227609cd6fcf6c3133751a89eb Related: OS#4796 SYS#5114

2020-11-09gsm_08_58: add proprietary IE to signal Repeated ACCH CapabilityPhilipp Maier1-0/+3
3GPP TS 24.008, section 10.5.1.7 specifies a Repeated ACCH Capability bit in the Classmark 3 IE. Unfortunately, there is no way specified how the Repeated ACCH feature should be controlled on RSL level. Since it is not unusual that BTS/BSC vendors occassionally add proprietary IEs to different RSL messages we may pick this as a solution as well and add a propritary RSL_IE_OSMO_REP_ACCH_CAP IE, so that we can enable repeated FACCH/SACCH on the BTS side when we send RSL CHAN ACT or RSL CHAN MODE MODIFY messages.

2020-10-07add GAD coding for Location ServicesNeels Hofmeyr1-0/+172
GAD, Universal Geographical Area Description: - raw coding for all GAD elements. - SI-units encoding and decoding for Ellipsoid point with uncertainty circle, which I presume is the typical "at most N meters away from cell tower located at X,Y", which corresponds to the TA positioning currently being implemented. - other SI-units GAD element encodings are so far not implemented. Add encoding and decoding tests. In gsm/protocol/gsm_23_032.h are the raw coding structs as defined in 3GPP TS 23.032. In gsm/gad.h are structs carrying consistent units based on meters and degrees, for convenient / less error prone handling of GAD data, and for human readable representations of the GAD data. The separation of the two is desirable because OsmoBSC will receive GAD data from OsmoSMLC on the Lb interface, and pass on this data to the MSC via the A interface. It is better to pass the GAD data as-is without de/encoding. Change-Id: I7a9dd805a91b1ebb6353bde0cd169218acbf223c

2020-05-15cosmetic: apply changes to match struct_endianess.py outputNeels Hofmeyr3-14/+8
gsm48_pag_resp and gsm48_service_request: omit comments in big endian part. dtap_header: better segment the substruct. gsm23041_msg_param_gsm: match up whitespace / comments. Rationale: the script is a good way to avoid bugs from manually composing the big endian parts (for example, it detected the missing endian.h include, fixed in I593cc5e8272469b570559206bb02b6e79797340b). However, it becomes cumbersome if it creates numerous edits in the source tree, which cause more time spent for whoever wanted to rather save time with it. So let's keep the code tree matching that struct's output. Change-Id: I7432f5337d6589262c31f5186dfd0ac32221c467

Affected: - struct gsm48_range_1024 - struct gsm48_range_512 - struct gsm48_range_256 - struct gsm48_range_128 In commit [1], the automatic little-to-big-endian compatibility by struct_endianness.py introduced doubled little/big endian struct listings by accident, resulting in a wrong big endian structure (due to double reversal in the original big endian part).
