( https://gerrit.osmocom.org/9358 Change subject: mgcp: hack to keep IuUP working ...................................................................... mgcp: hack to keep IuUP working Since change If9a81d057f73150e483286472e73c45e7a453a6d removes the RTP loopback at the beginning. This also means that the Hack we do to run the IuUP negotiation via looping back the first few RTP packets will not work anymore. However, we should keep that hack as long as we do not have IuUP support in the MGW. - Start RTP connection in loopback mode for IuUP Change-Id: I4c7d90de4dc87e8baf7cf4a0c69d0e9e8c92e27b --- M src/libmsc/msc_mgcp.c 1 file changed, 40 insertions(+), 0 deletions(-) git pull ssh://gerrit.osmocom.org:29418/osmo-msc refs/changes/58/9358/1 diff --git a/src/libmsc/msc_mgcp.c b/src/libmsc/msc_mgcp.c index 67a2142..c77e389 100644 --- a/src/libmsc/msc_mgcp.c +++ b/src/libmsc/msc_mgcp.c @@ -278,10 +278,22 @@ struct msgb *msg; int rc; +#ifdef BUILD_IU + struct gsm_trans *trans; + struct gsm_subscriber_connection *conn; +#endif + OSMO_ASSERT(mgcp_ctx); mgcp = mgcp_ctx->mgcp; OSMO_ASSERT(mgcp); +#ifdef BUILD_IU + trans = mgcp_ctx->trans; + OSMO_ASSERT(trans); + conn = trans->conn; + OSMO_ASSERT(conn); +#endif + /* NOTE: In case of error, we will not be able to perform any DLCX * operation because until this point we do not have requested any * endpoint yet. */ @@ -302,6 +314,14 @@ return; } + /* HACK: We put the connection in loopback mode at the beginnig to + * trick the NodeB into doing the IuUP negotiation with itsself. + * this is a hack we need because osmo-mgw does not support IuUP yet */ +#ifdef BUILD_IU + if (conn->via_ran == RAN_UTRAN_IU) + mgcp_msg.conn_mode = MGCP_CONN_LOOPBACK; +#endif + msg = mgcp_msg_gen(mgcp, &mgcp_msg); OSMO_ASSERT(msg); @@ -377,10 +397,22 @@ struct msgb *msg; int rc; +#ifdef BUILD_IU + struct gsm_trans *trans; + struct gsm_subscriber_connection *conn; +#endif + OSMO_ASSERT(mgcp_ctx); mgcp = mgcp_ctx->mgcp; OSMO_ASSERT(mgcp); +#ifdef BUILD_IU + trans = mgcp_ctx->trans; + OSMO_ASSERT(trans); + conn = trans->conn; + OSMO_ASSERT(conn); +#endif + switch (event) { case EV_CRCX_RAN_RESP: break; @@ -405,6 +437,14 @@ return; } + /* HACK: We put the connection in loopback mode at the beginnig to + * trick the NodeB into doing the IuUP negotiation with itsself. + * this is a hack we need because osmo-mgw does not support IuUP yet */ +#ifdef BUILD_IU + if (conn->via_ran == RAN_UTRAN_IU) + mgcp_msg.conn_mode = MGCP_CONN_LOOPBACK; +#endif + msg = mgcp_msg_gen(mgcp, &mgcp_msg); OSMO_ASSERT(msg); -- To view, visit https://gerrit.osmocom.org/9358 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: osmo-msc Gerrit-Branch: master Gerrit-MessageType: newchange Gerrit-Change-Id: I4c7d90de4dc87e8baf7cf4a0c69d0e9e8c92e27b Gerrit-Change-Number: 9358 Gerrit-PatchSet: 1 Gerrit-Owner: dexter <pmaier at sysmocom.de> -------------- next part -------------- An HTML attachment was scrubbed...
