FB Magma Core - with srsLTE eNB and UE

We assume either of the following is true:

1. The following instructions have been executed: http://iristestbed.eu/index.php/fb-magma-core

2. Experimenters are using our Magma EPC Core deployed.

 

1. edit the enb.conf file

vi /home/$USER/.config/srslte/enb.conf

mme_addr = <MME IP>
gtp_bind_addr = <eNB IP>
s1c_bind_addr = <eNB IP>

For example:
mme_addr = 10.154.50.75
gtp_bind_addr = 10.154.50.69
s1c_bind_addr = 10.154.50.69

Note 10.154.50.75 is Iris testbed MAGMA CORE IP address
