From 283c7fde3809d3bb010b736c4597641f3d290260 Mon Sep 17 00:00:00 2001 From: Harald Welte Date: Mon, 21 Dec 2015 23:35:56 +0100 Subject: Add WIP code for SCCP User Adaptation (SUA) and SCCP User SAP The idea of this code is to * provide a SCCP User SAP as boundary between the User of SCCP or SCCP-like transport like SUA * implement the minimum subset of SUA to transport RANAP messages betweene HNB-GW and MSC/SGSN At this point * we don't yet implement the proper state machines and timer * we don't imp[lement the SCCP RESET procedure * we don't implement AS/ASP management The code is full of FIXMEs whihc hopefully will get fixed gradually. After some cleanup + verification, it should move to a library, possibly either replacing/renaming libomo-sccp, or adding it to libosmo-netif? --- sigtran/sua_client_test.c | 57 +++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 57 insertions(+) create mode 100644 sigtran/sua_client_test.c (limited to 'sigtran/sua_client_test.c') diff --git a/sigtran/sua_client_test.c b/sigtran/sua_client_test.c new file mode 100644 index 0000000..552e0f0 --- /dev/null +++ b/sigtran/sua_client_test.c @@ -0,0 +1,57 @@ +#include "sua_test_common.h" + +struct osmo_sua_user *g_user; +struct sua_link *g_link; + +static int sccp_sap_up(struct osmo_prim_hdr *oph, void *link) +{ + struct osmo_scu_prim *prim = (struct osmo_scu_prim *) oph; + struct osmo_prim_hdr *resp = NULL; + uint8_t payload[] = { 0xa1, 0xa2, 0xa3 }; + + printf("sccp_sap_up(%s)\n", osmo_sccp_prim_name(oph)); + + switch (OSMO_PRIM_HDR(oph)) { + case OSMO_PRIM(OSMO_SCU_PRIM_N_CONNECT, PRIM_OP_CONFIRM): + printf("N-CONNECT.ind(%u), issuing DATA.req\n", + prim->u.connect.conn_id); + resp = make_dt1_req(prim->u.connect.conn_id, payload, sizeof(payload)); + break; + } + + if (resp) + osmo_osmo_sua_user_link_down(link, resp); + + msgb_free(oph->msg); + return 0; +} + + +int main(int argc, char **argv) +{ + void *ctx = talloc_named_const(NULL, 1, "root"); + int rc; + + osmo_sua_set_log_area(DSUA); + xua_set_log_area(DXUA); + + osmo_init_logging(&test_log_info); + + g_user = osmo_sua_user_create(ctx, sccp_sap_up); + + rc = sua_client_connect(g_user, "127.0.0.1", 2342); + if (rc < 0) { + exit(1); + } + + g_link = sua_client_get_link(g_user); + + int i = 8000; + + while (1) { + if (i < 8010) + tx_conn_req(g_link, i++); + //tx_unitdata(g_link); + osmo_select_main(0); + } +} -- cgit v1.2.3
