Hi Everyone, I would like to know if anyone has been able to connect an OCS to open5gs PCRF. I know OCS talks to the PCRF using the Sy interface and the Gy interface to connect to the PCEF Lastly, how do I define these interfaces? Regards,

Does anyone know why I am getting this reject reason for network entry on a UE? 03/17 16:56:55.026: [mme] DEBUG: [EMM] Authentication request (../src/mme/nas-path.c:180) 03/17 16:56:55.026: [mme] DEBUG: IMSI[311980000033212] (../src/mme/nas-path.c:181) 03/17 16:56:55.026: [mme] DEBUG: [MME] DownlinkNASTransport (../src/mme/s1ap-build.c:186) 03/17 16:56:55.026: [mme] DEBUG: ENB_UE_S1AP_ID[41] MME_UE_S1AP_ID[17] (../src/mme/s1ap-build.c:231) 03/17 16:56:55.026: [mme] DEBUG: IP[10.100.108.9] ENB_ID[67177119] (../src/mme/s1ap-path.c:79) 03/17 16:56:55.189: [mme] DEBUG: mme_state_operational(): MME_EVT_S1AP_MESSAGE (../src/mme/mme-sm.c:129) 03/17 16:56:55.189: [mme] DEBUG: s1ap_state_operational(): MME_EVT_S1AP_MESSAGE (../src/mme/s1ap-sm.c:60) 03/17 16:56:55.189: [mme] DEBUG: [MME] Uplink NAS transport (../src/mme/s1ap-handler.c:330) 03/17 16:56:55.189: [mme] DEBUG: IP[10.100.108.9] ENB_ID[67177119] (../src/mme/s1ap-handler.c:347) 03/17 16:56:55.189: [mme] DEBUG: ENB_UE_S1AP_ID[41] MME_UE_S1AP_ID[17] (../src/mme/s1ap-handler.c:354) 03/17 16:56:55.189: [mme] DEBUG: mme_state_operational(): MME_EVT_EMM_MESSAGE (../src/mme/mme-sm.c:129) 03/17 16:56:55.189: [emm] DEBUG: emm_state_authentication(): MME_EVT_EMM_MESSAGE (../src/mme/emm-sm.c:488) 03/17 16:56:55.189: [emm] DEBUG: [EMM] Authentication response (../src/mme/emm-sm.c:512) 03/17 16:56:55.189: [emm] DEBUG: IMSI[311980000033212] (../src/mme/emm-sm.c:513) 03/17 16:56:55.189: [emm] DEBUG: emm_state_authentication(): EXIT (../src/mme/emm-sm.c:488) 03/17 16:56:55.189: [emm] DEBUG: emm_state_security_mode(): ENTRY (../src/mme/emm-sm.c:649) 03/17 16:56:55.189: [mme] DEBUG: [EMM] Security mode command (../src/mme/nas-path.c:207) 03/17 16:56:55.189: [mme] DEBUG: IMSI[311980000033212] (../src/mme/nas-path.c:208) 03/17 16:56:55.190: [emm] DEBUG: Replayed UE SEC[LEN:2 EEA:0xe0 EIA:0xe0 UEA:0x0 UIA:0x0 GEA:0x0] (../src/mme/emm-build.c:287) 03/17 16:56:55.190: [emm] DEBUG: Selected[Integrity:0x1 Encrypt:0x0] (../src/mme/emm-build.c:289) 03/17 16:56:55.190: [mme] DEBUG: [MME] DownlinkNASTransport (../src/mme/s1ap-build.c:186) 03/17 16:56:55.190: [mme] DEBUG: ENB_UE_S1AP_ID[41] MME_UE_S1AP_ID[17] (../src/mme/s1ap-build.c:231) 03/17 16:56:55.190: [mme] DEBUG: IP[10.100.108.9] ENB_ID[67177119] (../src/mme/s1ap-path.c:79) 03/17 16:56:55.229: [mme] DEBUG: mme_state_operational(): MME_EVT_S1AP_MESSAGE (../src/mme/mme-sm.c:129) 03/17 16:56:55.230: [mme] DEBUG: s1ap_state_operational(): MME_EVT_S1AP_MESSAGE (../src/mme/s1ap-sm.c:60) 03/17 16:56:55.230: [mme] DEBUG: [MME] Uplink NAS transport (../src/mme/s1ap-handler.c:330) 03/17 16:56:55.230: [mme] DEBUG: IP[10.100.108.9] ENB_ID[67177119] (../src/mme/s1ap-handler.c:347) 03/17 16:56:55.230: [mme] DEBUG: ENB_UE_S1AP_ID[41] MME_UE_S1AP_ID[17] (../src/mme/s1ap-handler.c:354) 03/17 16:56:55.230: [mme] DEBUG: mme_state_operational(): MME_EVT_EMM_MESSAGE (../src/mme/mme-sm.c:129) 03/17 16:56:55.230: [emm] DEBUG: emm_state_security_mode(): MME_EVT_EMM_MESSAGE (../src/mme/emm-sm.c:649) 03/17 16:56:55.230: [emm] DEBUG: [EMM] Security mode complete (../src/mme/emm-sm.c:676) 03/17 16:56:55.230: [emm] DEBUG: IMSI[311980000033212] (../src/mme/emm-sm.c:677) 03/17 16:56:55.230: [mme] DEBUG: [MME] Update-Location-Request (../src/mme/mme-fd-path.c:444) 03/17 16:56:55.231: [emm] DEBUG: emm_state_security_mode(): EXIT (../src/mme/emm-sm.c:649) 03/17 16:56:55.231: [emm] DEBUG: emm_state_initial_context_setup(): ENTRY (../src/mme/emm-sm.c:817) 03/17 16:56:55.234: [mme] DEBUG: [MME] Update-Location-Answer (../src/mme/mme-fd-path.c:610) 03/17 16:56:55.234: [mme] DEBUG: Result Code: 2001 (../src/mme/mme-fd-path.c:651) 03/17 16:56:55.234: [mme] DEBUG: From 'hss.localdomain' (../src/mme/mme-fd-path.c:680) 03/17 16:56:55.234: [mme] DEBUG: ('localdomain') (../src/mme/mme-fd-path.c:693) 03/17 16:56:55.234: [mme] DEBUG: mme_state_operational(): MME_EVT_S6A_MESSAGE (../src/mme/mme-sm.c:129) 03/17 16:56:55.234: [mme] DEBUG: mme_state_operational(): MME_EVT_ESM_MESSAGE (../src/mme/mme-sm.c:129) 03/17 16:56:55.234: [mme] DEBUG: mme_bearer_find_or_add_by_message() [PTI:8, EBI:0] (../src/mme/mme-context.c:2847) 03/17 16:56:55.234: [esm] DEBUG: esm_state_initial(): ENTRY (../src/mme/esm-sm.c:38) 03/17 16:56:55.234: [esm] DEBUG: esm_state_inactive(): ENTRY (../src/mme/esm-sm.c:61) 03/17 16:56:55.234: [mme] INFO: Added a session.

Fwd: Open5GS Traffic Accounting
by Romeu Medeiros 11 Mar '20

11 Mar '20

Hello all and @Sukchan Lee <acetcom(a)gmail.com>, I was thinking about one way to generate traffic accounting from the LTE users of the Open5GS. I'm rearching something using the iptables (in Linux), in this link we can check a way to generate some traffic account in the linux: https://catonmat.net/traffic-accounting-with-iptables I'm thinking about writing a code, where the PGW adds a new line in iptables with the IP/IPv6 address (TRAFFIC_ACCT_IN and TRAFFIC_ACCT_OUT) when a new session is added and remove the same line when the session is ended, with this the counter will restart, being able to use an external program to get this information about the traffic sent and received by a given user. The bad from this idea is that this code only will work correctly in a Linux box. Does anyone have any other suggestions? Thanks Romeu Medeiros
