替换为:

测试功能,按照顺序打开四个独立Shell

 

 

 

正常启动之后,用手机(比如华为荣耀7)搜索运营型,可以找到一个名为20892的运营商,或者有些欧洲制式的手机可以正确的显示Eurecom这个法国电信运营商的名字。

OpenAir, single machine Ubuntu 17.04, after major EPC update

(updated: 2017, July 10th)

Modifs since version on July 6th:

  • Latest commit
  • Fix lacking file in the tarball
    (non modified ones since the June version were missing)
  • improved code pieces formating in HTML, added automatic git patch
  • Full re-test, from disk install of Ubuntu 17.04 to UE throughput measurement

This document explains how to install and configure OAI EPC+eNB on one single Ubuntu 17.04 64 bits machine connected with a regular UE (a Huawei E3272), routing the UE traffic to internet.

We use EPC after a major contribution in May 2017: a lot of code has been modified, all directories names were changes, configuration parameters names/values changed.

The description uses a USRP B210 board, a Lime SDR page is provided separately.

We also explain how to simplify, fix existing issues, to make a single computer as a full LTE network: EPC+eNB.

Known limitations fixed in the hereafter description

  • OAI EPC require kernel >= 4.7, so we have to use Ubuntu 17.04
    • We already pushed some enhancements in OAI, nevertheless some more are required
  • GTP UDP ports are in conflict for eNB and SGW
  • Useless link between OAI and the Ubuntu/Linux hostname removed
  • Several simplifications and precisions to make easier and reliable installations
