DIVISION EXPLOITATION & MAINTENANCE COMMUTATION.
Centre roaming international.
MSC (Mobile Switching Center) and MSS (Mobile
Switching System) are key components in the
architecture of a mobile telecommunications network,
such as the GSM (Global System for Mobile
Communications) and earlier 2G and 2.5G cellular
systems. These components play vital roles in the
call processing and routing of mobile phone calls.
Here's a detailed explanation of MSC and MSS:
2

1.2. Mobile Switching Center (MSC):
Role and Function:
The MSC is a central component in the network and serves as the
primary call processing entity in a mobile network. It acts as an
interface between the mobile devices and the fixed
telecommunications network, enabling the routing of calls and
data to their intended destinations.
3

Call Routing:
When a call is initiated from a mobile device, the MSC is responsible for
call setup, which includes call establishment, routing, and the necessary
handovers as the mobile device moves through different cell areas.
4

Subscriber Location Management:
MSCs also play a significant role in subscriber location management. They keep track of the location of mobile devices within
their service area. When a call is received for a mobile user, the MSC determines the user's current location and ensures that
the call is routed to the correct cell or location
5

Handovers and Roaming:
MSCs are crucial for managing handovers, which allow a mobile device to
switch from one cell to another during a call without interrupting the call.
Additionally, when a mobile device roams into a different service area or
network, the MSC facilitates call continuity and management in the visited
network.
6

Connection to Other Network Elements:
MSCs are connected to various network elements, including Base Station Controllers
(BSCs), Home Location Registers (HLRs), and other MSCs. These connections enable
the exchange of signaling and routing information.
7

Support for Voice and Data:
MSCs handle both voice and data traffic, allowing for services like voice calls, SMS (Short Message Service), and data
connections.
8

1.2. Mobile Switching System (MSS):
Definition and Purpose:
MSS, or Mobile Switching System, is a broader term that encompasses multiple components within a mobile network.
These components collectively facilitate mobile communication services, with the MSC being a central part of the MSS.
9

Components of MSS:
The MSS typically includes the MSC, Visitor Location Register (VLR), Home
Location Register (HLR), and other network elements. The VLR stores
subscriber information for visitors to a network, while the HLR stores
subscriber data for permanent network users.
10

Definition and Purpose:
MSS, or Mobile Switching System, is a broader term that encompasses multiple components within a mobile network.
These components collectively facilitate mobile communication services, with the MSC being a central part of the MSS.

To display links between MSS & MGW: LST M3LKS and LST M3LNK
To display all links: DSP M3LKS
To display the history of all the MSS We use the MSS SDM LMT platform -> Security Management -> Logs ->
Operation Log, and we select a start time and end time -> Run, and then
we obtain the result. 13

4.Basic MSC call flow
14

Detailed explanation of the call flow:
The call flow is for a voice call from a mobile station (MS) in BSC-A to a mobile station (MS) in BSC-B. The call is
routed through the Mobile Switching Center (MSC) and Visitor Location Register (VLR).
Step 1: The MS in BSC-A initiates the call by sending an Access Request message to the BSC.
Step 2: The BSC forwards the Access Request message to the MSC.
Step 3: The MSC authenticates the MS and verifies that it has enough credit to make the call.
Step 4: The MSC sends a Routing Information Request (SRI) message to the HLR. The HLR contains the routing information for
all subscribers in the network.
Step 5: The HLR sends a Routing Information Response (SRIres) message back to the MSC.
Step 6: The MSC selects a route for the call and sends a Call Setup Request (CSR) message to the VLR of the called party (BSC-
B).
15

Detailed explanation of the call flow:
Step 7: The VLR forwards the CSR message to the MS of the called party (BSC-B).
Step 8: The MS of the called party (BSC-B) sends a Call Setup Response (CSR) message back to
the VLR.
Step 9: The VLR forwards the CSR message back to the MSC.
Step 10: The MSC establishes a connection between the MS of the calling party (BSC-A) and
the MS of the called party (BSC-B).
Step 11: The call is now established and the parties can begin talking.
•CM_SERVICE_REQ: This message serves to request specific services or
actions from the MSC.
•BSSAP-A: This is a signaling protocol used between the MSC and BSC.
•MAP-B/C and MAP-B/D: These are signaling protocols used between the
MSC and VLR.
16

Before starting this section here are a
Global terms used in Roaming Center:
5.Huawei MSC config in a Roaming center
IMSI (International Mobile Subscriber Identity):
•A unique identifier associated with a subscriber's SIM card in the GSM and UMTS
networks. It is used to authenticate the subscriber and determine their home network.
Roaming Agreement:
•A formal contract or agreement between mobile network operators that allows subscribers from
one network to use the services of another network when they are outside their home network's
coverage area.
HPLMN (Home PLMN) and VPLMN (Visited PLMN):
•HPLMN is the subscriber's home network, and VPLMN is the network in which the subscriber
is currently roaming. These terms are used to differentiate between the home and visited
networks.
17

Roaming Steering:
•A technique used by network operators to control which visited network a subscriber's device connects to
when roaming to optimize cost and network quality.
Roaming Testing and Roaming Test SIMs:
•The process of testing and verifying the functionality and quality of roaming services. Special test SIM
cards are often used for these purposes.
Map (Mobile Application part):
•MAP is a signaling protocol that is used by the MSC, HLR, and VLR to exchange messages related to
user location, call routing, and other mobility management functions.
18

GTT (Global Title Translation):
•A key component of the SS7 (Signaling System 7) protocol used in telecommunications networks. GTT is
responsible for translating a called party's global title (typically an E.164 number) into a network-specific
address for call routing.
MCC (Mobile Country Code):
•A three-digit code that uniquely identifies a country in the
international mobile numbering plan.
MNC (Mobile Network Code):
•A two- or three-digit code that, when combined with the MCC, uniquely identifies a mobile network
operator within a country.
19

MSC configuration in a raoming center:
When a roaming center opens with a new operator at the MSC (Mobile Switching Center) level, the process
involves technical, operational, and administrative steps to enable mobile subscribers from the new operator to
roam onto the host network and access services.
At the operator's IR21 document level, the following data is verified:
MCC / MNC
MGT 214 (to be used for IMSI conversion)
Example: Vodacom Afrique du Sud, with MCC = 655, MNC = 01, MGT CC = 27, MGT NC = 82
For Huawei:
the command for opening (to list: LST IMSIGT:MCCMNC=K‘65501;)
-ADD IMSIGT:MCCMNC=K‘65501,CCNDC=K‘2782;
