Bug #6037
Updated by laforge 9 months ago
I am trying to establish internet connections to cell phones. I have seen the https://osmocom.org/projects/cellular-infrastructure/wiki/OpenBSC_GPRS but it is now outdated. However, I have searched in different repo and found some info. I have configured septu osmo-pcu, osmo-sgsn, osmo-ggsn, osmo-trx-uhd and osmo-bsc for egprs configuration. Generally, I use system service to run task. I am using my laptop with wlp1s0 and created tun0 network. I have attached my all config files. to run program: <pre> sudo systemctl restart osmo-msc.service osmo-stp.service osmo-hlr.service osmo-sgsn.service osmo-ggsn.service osmo-pcu.service osmo-bsc.service osmo-sip-connector.service osmo-bts-trx.service osmo-gtphub.service </pre> log: <pre> ip address 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: enp0s31f6: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN group default qlen 1000 link/ether ec:8e:b5:41:cb:90 brd ff:ff:ff:ff:ff:ff 3: wlp1s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether b8:8a:60:4f:59:02 brd ff:ff:ff:ff:ff:ff inet 10.104.130.84/20 brd 10.104.143.255 scope global dynamic noprefixroute wlp1s0 valid_lft 16248sec preferred_lft 16248sec inet6 fe80::9963:faf7:dce4:826c/64 scope link noprefixroute valid_lft forever preferred_lft forever 27: tun0: <POINTOPOINT,MULTICAST,NOARP> mtu 1500 qdisc noop state DOWN group default qlen 500 link/none osmo-sgsn.service - Osmocom SGSN (Serving GPRS Support Node) Loaded: loaded (/lib/systemd/system/osmo-sgsn.service; disabled; vendor preset: enabled) Active: active (running) since Thu 2023-05-18 12:07:47 +06; 56min ago Main PID: 24406 (osmo-sgsn) Tasks: 1 (limit: 9302) Memory: 2.7M CPU: 310ms CGroup: /system.slice/osmo-sgsn.service └─24406 /usr/bin/osmo-sgsn -c /etc/osmocom/osmo-sgsn.cfg May 18 12:07:47 MIST osmo-sgsn[24406]: <001f> osmo_ss7.c:458 0: Creating SCCP instance May 18 12:07:48 MIST osmo-sgsn[24406]: <001d> gsup_client.c:74 GSUP connecting to 127.0.0.1:4222 May 18 12:07:48 MIST osmo-sgsn[24406]: <0015> input/ipa.c:141 127.0.0.1:4222 connection done May 18 12:07:48 MIST osmo-sgsn[24406]: <0015> input/ipaccess.c:919 received ID_GET for unit ID 0/0/0 May 18 12:07:49 MIST osmo-sgsn[24406]: <0022> m3ua.c:623 0: asp-asp-clnt-OsmoSGSN: Received NOTIFY Type State Change:AS Inactive () May 18 12:07:49 MIST osmo-sgsn[24406]: <001f> xua_default_lm_fsm.c:361 xua_default_lm(asp-clnt-OsmoSGSN)[0x55752cea8a90]{ACTIVE}: Ignoring primitive M-ASP_ACTIVE.confi> May 18 12:07:49 MIST osmo-sgsn[24406]: <0022> m3ua.c:623 0: asp-asp-clnt-OsmoSGSN: Received NOTIFY Type State Change:AS Active () May 18 12:07:49 MIST osmo-sgsn[24406]: <0022> xua_snm.c:403 0: asp-asp-clnt-OsmoSGSN: Rx DAVA() for 0.23.1/0, May 18 12:07:49 MIST osmo-sgsn[24406]: <0020> sccp_scmg.c:298 unsupported SCCP user primitive N-PCSTATE.indication osmo-ggsn.service - OsmoGGSN Loaded: loaded (/lib/systemd/system/osmo-ggsn.service; disabled; vendor preset: enabled) Active: active (running) since Thu 2023-05-18 12:07:46 +06; 57min ago Main PID: 24401 (osmo-ggsn) Tasks: 1 (limit: 9302) Memory: 1.8M CPU: 253ms CGroup: /system.slice/osmo-ggsn.service └─24401 /usr/bin/osmo-ggsn -c /etc/osmocom/osmo-ggsn.cfg May 18 12:07:46 MIST systemd[1]: Started OsmoGGSN.
