YateUCN Configuration

Use YateMMI to configure your YateUCN. YateMMI is only installed on the first Yate-based machine you have purchased.

Starting up

1. To connect to YateMMI from the same machine where it is installed on, open a browser window and type in:

2. To connect to YateMMI from another machine located in the same network where it is installed, open a browser window and type in:

3. To connect to YateMMI from a machine outside the network where it is installed, and provided that you have the rights to do so, use SSH with a port forwarding to YateUCN. Open a console and type:

ssh ucn_user@ucn_ip -L local_port:

Open a browser window and type in:

You will be asked to provide system credentials (a valid username/password) to access the MMI.

Unified LTE/GSM+GPRS core network, including SGSN, GGSN, GMSC, MME, SGW, PGW
See the product here ››

Sign in

At the purchase of your Yate-based products you will also receive system log in credentials (username: yatebts, password: ‘same-as-serial‘), default MMI login credentials are:

username – admin
password – admin

YateUCN Configuration

This configuration example can be used if YateUCN and YateMMI are running on the same server.

MMI -> Equipment -> YateUCN -> [+] Edit node -> MME/SGSN

You can add multiple S1AP listeners, from “Add another SCTP Listener” located in the bottom right side of the MME – S1AP configuration section

MMI -> Equipment -> YateUCN -> [+] Control node -> Edit -> MME/SGSN

The S1 interface connects the eNodeB to the EPC, more exactly the MME. S1 can be split into control-plane (S1AP) and user-plane (S1-U)

The S1 Application Protocol (S1AP) supports the functions of S1 interface by signalling procedures defined in ETSI TS 136 413 V10.0.1“.

As S1AP interface handles only signaling (control-plane) between eNodeB and MME, we need to setup interface to transport user-plane data.
S1-U transports user-plane data (GTP-U messages) across a GTP user plane tunnel.

You can set up S1-U user-plane interface, on the same MMI page, from “S1 GTP interface(s)” (blue ca in MMI) -> Add.

  • Custom GT for VLR mode -> From here you can specify a custom global title for the VLR.
  • IPv4 GTP address (Ex:
  • IPv6 GTP address
  • Custom GT for SGSN mode -> Check if SGSN has a custom global title (GT)
  • Custom GT for GGSN mode -> Check if GGSN has a custom global title (GT)
