Data Network and SMS (over NAS)

Data Network and SMS (over NAS)

In this guide I present how to set up Data Network for SMS (over NAS) in YateMMI step by step.

The IPs / GTs / MSISDN and any other resources are internal conventions and don’t map to real settings in any way for this MCC/MNC operator.

Before setting up everything in MMI, I write an IP plan and a Network Plan. Then, I install the MMI and Yate Products, I setup Baicell, followed finally by the MMI set-up.  Following every step in this order:

1. IP Plan

2. Network Plan (ports, GTs, PCs)

3. Install MMI and products
 
4. Setup Baicell
 
5. MMI setup

IP Plan

It is absolutely necessary to set multiple interfaces on a server (using aliases or VLAN ), when having multiple features on the same server or even for separating traffic based on role or protocols.
 
For example:
  • When I have both PGW and SGSN on the same server, due to the fact that GTP does not accept to change ports.
  • Unless I will set 2 YateUCNs with different features support, I need a workaround for using both features on same machine.
  • This is the reason why I need to create multiple interfaces.

Install YateMMI and products

After creating the IP pan and the Network plan, I start installing YateMMI and the products I need.

Setup Baicell

For the next step I setup the Baicell according to my configurations.

YateMMI Setup

After all the preparations are done, I start adding all the info in YateMMI.

When I set up YateMMI, I carefully check that I pass through all the necessary steps:

  • 1. Network Settings
  • 2. Editing Network Settings
  • 3. Equipment / Core
  • 4. Profile Management
  • 5. Subscriber Management

Network Settings

General:

MCC=232, MNC=03, CC=43, NDC=3323, NNSF bits=8, NNSF bits data=8

MSISDN prefixes: 433323 (based on declared values)

SS7, Diameter support are enabled

SS7 step:

GT prefixes: 4333231 (based on declared values)

SMSC GT: 4333231000 (based on declared values)

Dialect : ANSI 

Netindicator : national 

DIAMETER step:

For the Diameter step, I check if suggested value for Diameter Realms and IMS Domain are based on MCC and MNC.

 APNs step:
– add internet.t-mobile.at apn
         IP version – iPv4v6
         QoS true
Primary DNS IPv4 – 192.168.168.1 (this is used by our team for tests, in production usually the APNs Primary DNS IPv4 is 8.8.8.8)
Aliases – internet.apn.epc.mnc003.mcc232.3gppnetwork.org
QCI – 9  
GGSN/PGW Address (for S8 interface)  – 10.35.50.151 (the IP used to build S8 interface in UCN)

Profile Management

SIM Profile

  • I choose to add default profiles (using ‘Add default profile’ button) (I unchecked IMS profile and 5G profile)

PS Profile

  • APN name is the one requested by the Baicell

EPS Profile

  • Default EPS Profile: APN name is the one requested by the Baicell

Subscriber Management

SIM

  • Import SIMs (I use decrypt key if needed) with SIM Profile – DefaultISIM
  • Add MSISDN to each SIM (Ex. 43332300008) with IMSI; ICCI; IMS Profile = not active

The SIM cards I use should also contain according information: IMSI, Domain, IMPI, IMPU, SMSP with SMSC GT.
