UE not connecting to srsran #787

Closed idonttest closed 1 year ago

idonttest commented 2 years ago

So i am running srsran recent release on ubuntu using USRP b210. UE is Motorola G5s Plus.

Below are the changes I made in the config

epc.conf

[mme] mme_code = 0x1a mme_group = 0x0001 tac = 0x0007 mcc = 001 mnc = 01 mme_bind_addr = 127.0.1.100 apn = srsapn dns_addr = 8.8.8.8 encryption_algo = EEA0 integrity_algo = EIA1 paging_timer = 2 request_imeisv = false

enb.conf

[enb] enb_id = 0x19B mcc = 001 mnc = 01 mme_addr = 127.0.1.100 gtp_bind_addr = 127.0.1.1 s1c_bind_addr = 127.0.1.1 s1c_bind_port = 0 n_prb = 15 tm = 2 nof_ports = 2

[rf] dl_earfcn = 1934

1934

tx_gain = 60 rx_gain = 40

user_data.cfg

ue2,mil,001010123456780,00112233445566778899aabbccddeeff,op,63bfa50ee6523365ff14c1f45f88737d,8000,000000001656,7,dynamic ue1,xor,001010123456789,00112233445566778899aabbccddeeff,opc,63bfa50ee6523365ff14c1f45f88737d,9001,000000001234,7,dynamic

The SIM card is configured as followed. image

My phone can detect the 001 01 network as CMCC. but the phone doesn't register to the network.

Is there something i am doing wrong??

Try upping your resource blocks to 50?

@Jackrabrett After increasing the resource block to 50. Now my phone cannot detect the network all together.. Anything other than 15 doesn't show in the phone

Thanks..

Jackrabrett commented 2 years ago

Look at your UE config file, it has op instead of opc. On your sim editor you have opc selected try that

I’m actually not seeing the SIM data that matches your editor in your ue config file, just ue1 and ue2. Did you add your SIM card info in there?

@Jackrabrett Thanks.. That was a stupid mistake of mine. Even after fixing it, the SIM card won't register with the network.. I changed my earfn_dl to 500 which is band 1. same issue.. played around with all setting on enb & epc.. I recreated the same using LimeSDR and same issue persist. I am assuming the problem is either in the UE or the SIM card itself.

I used the default ue2 values on my sim .

JM-Lemmi commented 2 years ago

Have you tried a different MCC/MNC from 001/01? I have read, that some devices refuse connecting to 001/01

Jackrabrett commented 2 years ago

I’ve had good luck on Band 8

Also, make sure you add the APN in your phone settings that matches your epc.conf file apn settings
