How can I connect eNB to an external EPC ?
The following parameters should be changed in your enb config file to point to the external EPC:
- mme_addr: This is the address of S1AP connection. It must be modified if the MME runs on a different host.
- gtp_addr: This is the GTP bind address, ie the address of the Ethernet interface connected to MME/EPC. It must be modified if the MME runs on a different host. */
- plmn_list: This is the broadcasted PLMN identities. It should be changed to match the one in MME/EPC.
Let's say your EPC is running on a PC with IP = “192.168.30.1” and eNB is running on a PC with IP=“192.168.30.2”, the configuration shall be done as following at eNB sidemme_addr: “192.168.30.1”,gtp_addr: “192.168.30.2”,
It is also better to disable the automatic lte service and run the eNB manually
- service lte stop
- cd /root/enb
- ./lteenb config/enb.cfg
