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 12 Mar '20

12 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

Any major issues on master?
by Spencer Sevilla 02 Nov '19

02 Nov '19

Hi everyone, I admin a couple of small-scale networks, one with ~20 users and one with ~100. They are basic, data-only LTE networks, and do not provide any voice services, 2g fallback, or interconnect at all. One has two eNBs and the other has one. We currently use the OAI EPC, but are very interested in moving over to NextEPC for reasons of stability. I’ve tested NextEPC in our lab (with only two phones and an SDR) and it seems to work great. I’ve looked through the code, implemented a feature or two, and it is much much cleaner than OAI. I’ve also heard widely good reports of some other deployments. Anything I should know, or any major issues I should be aware of before I go ahead and deploy the current master branch? I don’t mind finding/fixing a couple of bugs and will certainly commit any fixes upstream, just more asking about any already known fundamental problems, features unimplemented, or reasons I should postpone a rollout. Thanks! Spencer

Regarding configuration files.
by Murali Sb 04 Oct '19

04 Oct '19

Hi I have a question regarding conf files in nextEPC. I know for example, mme.conf is generated from mme.conf.in, so I've added few of my configuration settings in mme.conf.in and same is populated in mme.conf. I use the same YAML parser to read my new configurations. It's working. I've a problem now, How is nextEPC reading these parameters? and from where? I know I've to update a structure for this. But I don't know which structure. Anybody done this before? any help is really appreciated. Thanks Murali
