• 2 MSC (geo redundant)

• 3 BSC (in redundant concept)

• 1 GPRS system

• 1 SMS center

• 1 centralized recording system

• 2 GSM-R Dispatcher Call Servers

• 75 compact Call Servers

10

Work packages

WP1 – Cabling

• Cca 900 km of optical cables and 300 km of power cables

• Demanding design mostly new cabling, smaller part of the re-used existing cables

• Huge amount of construction work (excavation, taking into account the geographical characteristics of the terrain)

Metal ducts

Concrete ducts

Digging

WP3 – Transport network SDH, IP

• Based on SDH and Ethernet data transmission technology

• The integration into an existing network (TDM - E1,) for alternative routing

• The transport network across the main routes of transmission provides complete redundancy using a ring topology on separate physical connections

• Segment the network provides a high degree of control over traffic

Layer one (MSC / BSC connection) and layer two (BSC / BTS) example

Difference between main lines (double ring) and regional lines (single ring)

13

WP4 – Fixed dispatching system for GSM-R

• Solution supporting modern (fixed and mobile) and legacy technologies (LB, CB, analogue 2-w and 4-w trunks, announcement systems...) within a single dispatcher terminal.

• IP based architecture

– centralized for parts where main GSM-R functionality is provided

– decentralized where the locally connected lines have to be handled

• Dispatchers are connected over IP/Ethernet

• The communication system includes all the existing subscriber and transmission lines and enables communication with GSM-R mobile part , fixed system of ŽAT telephony , SMS services and central recording system.

• The layout is redundant – geo-redundancy at two locations in LJ and MB

14

WP5 – GSM-R infrastructure (core)

Next generation IP voice network solution based on the 3GPP Release 4 standards.Network design/ planning / dimensioning/ confirmation and system integration of all main core systems:

NSS Network Switching SubsystemBSS Base Station Subsystem (BSC with BTS-R)GPRS systemSMS centerVoice recording system

15

WP6 – GSM-R Mobile terminals

• General purpose handhelds (GPH) – 1.100 pcs

• Operational purpose handhelds (OPH) for field service staff – 370 pcs

• Operational purpose handheld for shunting (OPS) for staff participating in shunting works –190 pcs

• „Portable“ CAB radio – 50 pcs • Heavy duty

• Main functionalities:– Emergency call,

– Push-to-Talk

– SMS

BTS loops and their connection to BSC

3 BSC redundant to each other

The SZ network is composed by two NSS in geo-redundant mode and three BSS which manage 1/3 of the BTSs each.

In the Slovenian railway network we have three Traffic Management Centers shown on the picture bellow.For implementing LDA functionality we optimize the reselection zones between the different radio cells.

Traffic Management Centers

20

Radio cells allocated in the line (38 km)Average distance between BTS‘s in this section is 3,4 km

LDA functionalities

GSM-R network is designed to take into account the Slovenian railway operating program.According to this plan, each cell will be attached to the specific primary controller or/and secondary controller.

21

Integration of existing analog telephony and GSM-R into ONE dispatcher platform

22

GSM-R applications based on GPRS packet switch will be implemented after the formal acceptance of GSM-R network.

Developing of this applications needs cooperation with IT sector as well as traffic operating staff.

ApplicationsFuture steps

We defined already some of them like:- Ticketing- Time tables on the train and for train drivers- Departure documents for train driver (order for departure)- Sending data from counters for electrical consuming on the locomotives

Early detection of danger situations on the railway lines and around with: - Fire detection with sensors installed on the GSM-R masts- Flood detection - Landslide detection

Gathering all this information on the same platform for supporting the staff in dispatcher centers for quick and correct response and action.
