From 3571769bef1384596e8dd446e5bd851abf84c7c0 Mon Sep 17 00:00:00 2001 From: Robert Schmidt Date: Mon, 11 Apr 2022 18:22:10 +0200 Subject: [PATCH] Correctly initialize RLC when using phy-test mode When using phy-test mode, the RNTI for PDCP/RLC initialization would be 0, incorrectly initializing these layers, fixed in this commit. Additionally, in this commit, we only trigger the initialization in cases where the UE context is initialized (before, the RNTI might be 0 in other cases as well). --- openair2/RRC/NR/rrc_gNB_nsa.c | 47 +++++++++++++++++------------------ 1 file changed, 23 insertions(+), 24 deletions(-) diff --git a/openair2/RRC/NR/rrc_gNB_nsa.c b/openair2/RRC/NR/rrc_gNB_nsa.c index bb66d1513b..3f41c69d72 100644 --- a/openair2/RRC/NR/rrc_gNB_nsa.c +++ b/openair2/RRC/NR/rrc_gNB_nsa.c @@ -339,8 +339,6 @@ void rrc_add_nsa_user(gNB_RRC_INST *rrc,struct rrc_gNB_ue_context_s *ue_context_ sizeof(X2AP_ENDC_SGNB_ADDITION_REQ_ACK(msg).rrc_buffer)); X2AP_ENDC_SGNB_ADDITION_REQ_ACK(msg).rrc_buffer_size = (enc_rval.encoded+7)>>3; itti_send_msg_to_task(TASK_X2AP, ENB_MODULE_ID_TO_INSTANCE(0), msg); //Check right id instead of hardcoding - } else if (get_softmodem_params()->do_ra || get_softmodem_params()->sa) { - PROTOCOL_CTXT_SET_BY_MODULE_ID(&ctxt, rrc->module_id, GNB_FLAG_YES, ue_context_p->ue_id_rnti, 0, 0,rrc->module_id); } rrc->Nb_ue++; @@ -374,36 +372,37 @@ void rrc_add_nsa_user(gNB_RRC_INST *rrc,struct rrc_gNB_ue_context_s *ue_context_ } if(m == NULL){ + PROTOCOL_CTXT_SET_BY_MODULE_ID(&ctxt, rrc->module_id, GNB_FLAG_YES, ue_context_p->ue_id_rnti, 0, 0, rrc->module_id); LOG_W(RRC, "Calling RRC PDCP/RLC ASN1 request functions for protocol context %p with module_id %d, rnti %x, frame %d, subframe %d eNB_index %d \n", &ctxt, ctxt.module_id, ctxt.rnti, ctxt.frame, ctxt.subframe, ctxt.eNB_index); + + nr_rrc_pdcp_config_asn1_req(&ctxt, + get_softmodem_params()->sa ? ue_context_p->ue_context.rb_config->srb_ToAddModList : (NR_SRB_ToAddModList_t *) NULL, + ue_context_p->ue_context.rb_config->drb_ToAddModList , + ue_context_p->ue_context.rb_config->drb_ToReleaseList, + (ue_context_p->ue_context.integrity_algorithm << 4) | ue_context_p->ue_context.ciphering_algorithm, + NULL, /* kRRCenc - unused */ + NULL, /* kRRCint - unused */ + kUPenc, /* kUPenc */ + kUPint, /* kUPint */ + NULL, + NULL, + ue_context_p->ue_context.secondaryCellGroup->rlc_BearerToAddModList); + + nr_rrc_rlc_config_asn1_req (&ctxt, + get_softmodem_params()->sa ? ue_context_p->ue_context.rb_config->srb_ToAddModList : (NR_SRB_ToAddModList_t *) NULL, + ue_context_p->ue_context.rb_config->drb_ToAddModList, + ue_context_p->ue_context.rb_config->drb_ToReleaseList, + (LTE_PMCH_InfoList_r9_t *) NULL, + ue_context_p->ue_context.secondaryCellGroup->rlc_BearerToAddModList); + + LOG_D(RRC, "%s:%d: done RRC PDCP/RLC ASN1 request for UE rnti %x\n", __FUNCTION__, __LINE__, ctxt.rnti); } - nr_rrc_pdcp_config_asn1_req(&ctxt, - get_softmodem_params()->sa ? ue_context_p->ue_context.rb_config->srb_ToAddModList : (NR_SRB_ToAddModList_t *) NULL, - ue_context_p->ue_context.rb_config->drb_ToAddModList , - ue_context_p->ue_context.rb_config->drb_ToReleaseList, - (ue_context_p->ue_context.integrity_algorithm << 4) | ue_context_p->ue_context.ciphering_algorithm, - NULL, /* kRRCenc - unused */ - NULL, /* kRRCint - unused */ - kUPenc, /* kUPenc */ - kUPint, /* kUPint */ - NULL, - NULL, - ue_context_p->ue_context.secondaryCellGroup->rlc_BearerToAddModList); - - nr_rrc_rlc_config_asn1_req (&ctxt, - get_softmodem_params()->sa ? ue_context_p->ue_context.rb_config->srb_ToAddModList : (NR_SRB_ToAddModList_t *) NULL, - ue_context_p->ue_context.rb_config->drb_ToAddModList, - ue_context_p->ue_context.rb_config->drb_ToReleaseList, - (LTE_PMCH_InfoList_r9_t *) NULL, - ue_context_p->ue_context.secondaryCellGroup->rlc_BearerToAddModList); - - LOG_D(RRC, "%s:%d: done RRC PDCP/RLC ASN1 request for UE rnti %x\n", __FUNCTION__, __LINE__, ctxt.rnti); - } void rrc_remove_nsa_user(gNB_RRC_INST *rrc, int rnti) {
