srsRAN中,运行srsepc,srsenb超时

将srsRAN自带的epc.conf.example和enb.conf.example调用出来测试,但是二者无法成功连接,一直提示

[INFO] [UHD RF]Tx while waiting for EOB, timed out... 9.82398 >= 7.43586. Starting new burst...
[INFO] [UHD RF]Tx while waiting for EOB, timed out... 17.0041 >= 15.4138. Starting new burst...
[INFO] [UHD RF]Tx while waiting for EOB, timed out... 36.6851 >= 36.6851. Starting new burst...

这个是什么原因导致的呢?没有更改example里面的内容,直接复制出来的文件进行运行测试。


另外,user_db.csv应该如何配置呢?里面内容怎么填写呢?包含内容如下

Name,Auth,IMSI,Key,OP_Type,OP/OPc,AMF,SQN,QCI,IP_alloc"
#
# Name: Human readable name to help distinguish UE's. Ignored by the HSS
# Auth: Authentication algorithm used by the UE. Valid algorithms are XOR
# (xor) and MILENAGE (mil)
# IMSI: UE's IMSI value
# Key: UE's key, where other keys are derived from. Stored in hexadecimal
# OP_Type: Operator's code type, either OP or OPc
# OP/OPc: Operator Code/Cyphered Operator Code, stored in hexadecimal
# AMF: Authentication management field, stored in hexadecimal
# SQN: UE's Sequence number for freshness of the authentication
# QCI: QoS Class Identifier for the UE's default bearer.
# IP_alloc: IP allocation stratagy for the SPGW.

timed out 是由于有延迟,在虚拟机上安装低延迟内核过后依旧无法彻底解决这问题。所以需要安装一个Ubuntu系统的PC机,这样可以解决掉延迟问题。
user_db.csv里面关键需要获得IMSI,KEY,OPC这三组数,其余的按照示例来填写即可。上述三组数一般需要读卡器来进行读取,但是key(ki)以及opc都是加密内容,是无法直接读取的,实验过程中选用白卡(可编程卡)进行读写,完成实验。
