You have rather old versions of osmocom software. Latest osmo-bts is 
1.3.2 and osmo-pcu 0.9.0. I don't know where did you get them from, but 
first of all you should upgrade to latest stable. Check Osmocom OBS 
repositories.



Would you kindly advise whats going on please….
As i understand osmo-pcu is to implement GPRS into my GSM network… ok 
but if i dont want GPRS implemented thus i dont need PCU …. can i run 
virtual bts without this PCU things ?


Sure you can use your network/bts without gprs. Make sure to use VTY 
option "gprs mode none" in your osmo-bsc.cfg, and avoid setting any TS 
to PDCH ("phys_chan_config PDCH")

PCU socket has LOST connection

2021-09-05 Thread Mario Lucas 

Dear All,
 
I try to run a virtual BTS:
 
systemctl start osmo-stp
systemctl start osmo-hlr
systemctl start osmo-msc
systemctl start osmo-bsc
 
and finally i run osmo-bts-virtual…. but i am getting following outcome:
 
DOML <0001> oml.c:91 OC=GPRS-CELL INST=(00,ff,ff): Sending PCU version report 
to BSC: PCU socket has LOST connection
DPCU <0009> pcu_sock.c:1084 PCU socket connected to external PCU
DPCU <0009> pcu_sock.c:967 Received 212 bytes on PCU Socket, but primitive size 
is 1006, discarding
DPCU <0009> pcu_sock.c:895 PCU socket has LOST connection
 
I tried to run osmo-pcu (I thought may be this will resole above issue) but it 
keeps saying:
 

<000b> gprs_ns.c:322 NSVCI=65534 Creating NS-VC with Signal weight 1, Data 
weight 1
<000e> telnet_interface.c:104 Available via telnet 127.0.0.1 4240

<0001> pcu_l1_if.cpp:114 Sending 0.8.0 TXT as PCU_VERSION to BTS
PCU interface version number of BTS (10) is different (9).
Please re-compile!
 
I have
OsmoPCU version 0.8.0
OsmoBTS version 1.2.0.307-6e27
 
 
Would you kindly advise whats going on please….
