* gsm_08_58.h: Introduce struct abis_rsl_chan_nrPau Espin Pedrol2018-10-211-3/+32
| | | | | | | | | | | | It will allow to make code handling chan_nr values more easier to read and less prone to errors. union is used to be able to get the full octet in case we need to pass it somewhere else or encode it. An extra union is used in struct abis_rsl_common_hdr and others to allow using fields directly while keeping API compatibility. Change-Id: Icd6822021207270a00106c50f8ca6b93c1250df9

* gsm0808: add function to convert amr gsm0408 setings to gsm0808Philipp Maier2018-09-191-0/+14
| | | | | | | | | | | | | | | | Add a function to convert struct gsm48_multi_rate_conf, which holds the codec settings for AMR, to S0-S15 bit representation as defined in 3GPP TS 48.008 3.2.2.49 This resurrects change-id I4e656731b16621736c7a2f4e64d9ce63b1064e98 which was reverted in I9e0d405e303ed86d23703ca6362e958dddb2f861 due to gsm0808_test failing. The test failure is fixed by properly clearing the struct gsm48_multirate_cfg prior to running tests (add memset(0)). Change-Id: Ia782e21c206c15e840226d79b4209d13658ee916 Related: OS#3548

* gsm0808: fix wrong codec defaults for OFR_AMR_WBPhilipp Maier2018-09-141-1/+1
| | | | | | | | | | | | | 3GPP TS 48.008 chapter 3.2.2.103 states that the configuration bits of OFR_AMR_WB are coded as follows: "S0, S2, S4 indicates the supported Codec Configurations. S1, S3, S5, S6, S7 are reserved and coded with zeroes." The current default setting of 0x3F violates this requirement. Lets set the "forbidden" settings zu zero and keep only the allowed ones.

* add gsm0808_cell_{id,id_list}_name() and friendsNeels Hofmeyr2018-04-181-1/+2
| | | | | | | | | | | | | | | | | | | | Provide comprehensive API to obtain string representations of Cell Identifiers and -Lists. Change gsm0808_test.c to use the new functions (which simplifies the output a bit), so that we don't duplicate printing code in gsm0808_test.c, and so that the not-so-trivial printing code is also tested. In gsm0808_test, also test gsm0808_cell_id_list_name_buf()'s return value and truncation behavior. The rationale for gsm0808_cell_id_list_name(), i.e. printing an entire list of cell identifiers, is that even though the maximum is 127 elements, a list of more than a few elements is hardly ever expected in practice (even more than one element isn't actually expected: either "entire BSS" or a single LAC). It is thus useful to log the entire list when it shows up in Paging and Handover. Change-Id: I9b2106805422f96c5cc96ebb9178451355582df3
* protocol/gsm_04_08.h: drop incorrect GSM48_PDISC_USSDVadim Yanitskiy2018-04-171-1/+0
| | | | | | | | | | | | According to the GSM TS 04.07, section 11.2.3.1.1 "Protocol discriminator", bits 1 to 4 of the first octet of a standard L3 message contain the protocol discriminator IE. Meanwhile, the GSM48_PDISC_USSD represents value 0x11, i.e. 0b10001, that requires 5 bits, and moreover it is not documented anywhere. Let's drop it.

* add gsm48_reject_value_namesNeels Hofmeyr2018-04-091-0/+4
| | | | | | | | | | | | | | There seems to be quite some confusion / overlap between enum gsm48_reject_value, gsm48_gsm_cause and gsm48_gmm_cause. I tried to go with gsm48_gsm_cause_names[], but e.g. GSM48_REJECT_CONGESTION is not represented. Instead of attempting to mix/merge those enums, provide a separate value string array for enum gsm48_reject_value. This will be used by osmo-msc's libvlr (refactoring of FSM result handling), I27bf8d68737ff1f8dc6d11fb1eac3d391aab0cb1. Change-Id: I6661f139e68a498fb1bef10c266c2f064b72774a
* gsm_08_08: correct speech codec defaultsPhilipp Maier2018-03-231-4/+4
| | | | | | | | | | | | The speech codec defaults are not correct. The defaults recommended in 3GPP TS 28.062, Table 7.11.3.1.3-2 are limited by 3GPP TS 48.008, Section 3.2.2.103. Some defaults are actually reserved for future use. Also the endianess of the 16 bit values is reversed. - correct values so that they match the specification - transmit bytes in the correct endianess Change-Id: I6c3a34d39a375d71c4128fd38f06629e8b98b100
* support for more cell ID list types in libosmocoreStefan Sperling2018-03-131-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | Introduce gsm0808_dec_cell_id_list2() with supports additional types of cell identifier lists. The new parsing routines are based on similar routines used by the paging code in osmo-bsc's osmo_bsc_bssap.c. Likewise, introduce gsm0808_enc_cell_id_list2() with support for the same additional types of cell identifier lists. The old API using struct gsm0808_cell_id_list is deprecated. The previous definition was insufficient because it assumed that all decoded cell ID types could be represented with a single uint16_t. It was declared in a GSM protocol header (gsm/protocol/gsm_08_08.h) despite being a host-side representation of data in an IE. The only user I am aware of is in osmo-msc, where this struct is used for one local variable. osmo-msc releases >= 1.1.0 make use of this API. While here, fix a small bug in a test: test_gsm0808_enc_dec_cell_id_list_bss() set the cell ID type to 'LAC' but obviously wants to use type 'BSS'.

* gsm48_hdr_msg_type[_r99]: Fix bit-masksHarald Welte2018-02-031-2/+2
| | | | | | | | | | TS 24.007 is quite clear: The upper two bits of the message type octet are *not* part of the message type in any of the L3 protocols which implement sequence numbers. it doesn't matter if it's R98 or R99, or whether the sequence number is 1bit or 2bits wide.
