GSM-R is the communications system used as the train radio and for emergency situations.

GSM-R, “GSM for Rail,” is built upon the mobile standard for GSM and is customized toward the railway’s special functions along with extensive demands for security and availability. This is a common European communications system that enables international rail traffic and interoperability, increases the efficiency of the railway service and allows new services for the users. Interoperability

Interoperability of the GSM-R system is the ability for GSM-R radios from abroad, with access to the Norwegian network, to function as prescribed. Terminals to be used in the Norwegian GSM-R network must meet the requirements in chapter

Terminals with a foreign SIM-card are expected to perform in a like manner as with a JBV Nett SIM-card. The services available to terminals using a foreign SIM-card should be the same as with using a JBV Nett SIM-card.

The EIRENE Specifications provide the framework for interoperability (for mobile communications). They underpin the EC Directive on the Trans-European High Speed Rail Network, along with other specifications being developed by the UIC.

At the highest level it is the Interoperability Directive (96/48/EC) which sets the overall framework and which must be adopted into national law by each of the Member States. The Interoperability Directive refers to a set of TSIs (Technical Standards for Interoperability). These TSIs provide more detailed descriptions of the requirements for the subsystems to which they relate. Of particular interest for the radio communications system is the TSI Control Command. Roaming

Subscribers from other GSM-R operators in Europe will have access to roam in the Norwegian GSM-R network if the foreign operator has an agreement with Bane NOR for roaming. Foreign subscribers who are roaming in the Norwegian GSM-R network will have access to the same services as Bane NOR’s subscribers. Coverage

All sections of the Norwegian rail network, including all tunnels, have GSM-R coverage. The entire network meets the requirements for coverage in EIRENE SRS. General GSM-R functions

General GSM-R functions are normal telephony/data services commonly made available from traditional mobile service and these will create the basis for additional specialized services.

  • Voice Communication
    The service provides for ordinary connections and transfer of voice and signal information between A and B subscriber. The service also satisfies Norwegian Authorities’ Rules and Regulations for civil emergency calls.
  • SMS
    The service provides for transfer of SMS to and from a message handling centre (SMSC) and a mobile terminal.
  • Circuit Switched Data
    The Norwegian GSM-R network supports circuit switched data communication BS26. The service has a data rate of 9,6 kbit/s. The service must be ordered, approved and activated on each subscription.
  • GPRS
    The Norwegian GSM-R network supports the GPRS service. The service must be ordered, approved and activated on each subscription. Specific GSM-R functions

Specific GSM-R functions are services designed especially for railway use. Some of the following services are also designed to support dependable and affective communication between the train operator and trains in transit.

  • Emergency Communication
    This service provides a high priority link to train drivers, traffic controllers and additional relevant personnel about hazardous situations within a predefined area, with the intent of avoiding undesirable situations.
  • Prioritization of calls
    This service provides the correct prioritization of calls within the GSM-R network.
  • Functional Numbers
    This service allows that a subscriber can be contacted via the subscriber’s functional roll instead of the number given the telephone terminal. The caller uses a functional number and the network selects the MSISDN (Mobil Station ISDN Number) for the SIM where the functional number is active.
  • Group Conversation
    This service provides the ability to set up a group conversation in half duplex mode between several subscribers from a predefined group.
  • Broadcast
    This service allows one way communication for warning and announcement of messages between an initiator and a group of subscribers.
  • Voice Recorder
    All conversations to or from a GSM-R terminal are recorded, stored and available for future listening if a special occurrence/accident requires documentation concerning related conversations/calls during this timeframe.
  • Acknowledgement Centre
    All terminals, both initiator and listeners, involved in an emergency call send a notification/receipt to an Acknowledgement Centre in the GSM-R network. The messages are stored in the Acknowledgement Centre so they can be accessed later if a special occurrence/accident requires documentation concerning related conversations/calls during this timeframe.
  • Train Operator and Block Post Keeper Services
    GSM-R service which ensures that train operator centres and Station Masters have access to all voice and message services. Requirements for GSM-R equipment

The GSM-R equipment and software must hold a valid EC Certificate of Conformity issued by a notified body that documents the compliance with EC Directive 2008/57/EC and Control command and signalling subsystems - CCS TSI, Commission Decision 2012/88/EU and all underlying specifications.

Only approved GSM-R terminals must be used. It is the user’s responsibility to ensure that the equipment being used at any given time is approved. Bane NOR recommends that the users contact their vendors for updated information regarding approval.

Further information regarding GSM-R terminals are available at Bane NOR’s website: GSM-R Subscriptions

To gain access to the GSM-R network the terminal must have a SIM-card installed. The SIM-card contains, among other things, information about which services are given access to dependent upon which function the terminal has. There is for example a profile for the train radio terminal for the train driver (cab-radio) and handheld terminals. When ordering a subscription (SIM-card) it is necessary to inform which use is intended. Customer Registration

Before a customer can use the GSM-R network there must be a customer/client relationship established between the customer and Bane NOR. The customer must fill out a “Customer Form”1. See URL-address below4 . The form must be filled out, signed and sent to Bane NOR’s Operations Centre (NOS), see chapter for contact information.

On the Customer Form the organization’s information will be filled in along with the billing address. Each customer which registers will be sent a bill for the subscriptions which are associated with them. If an organization consists of several units that desire their own bill a main agreement can be set up with the internal units registered as secondary customers. The secondary customers are also to be registered on the Customer Form, but it is important to specify the Department/Unit.

The following is also filled in on the “Customer Form”:

  • Customer Contact Person
  • Who will have authority to conduct ordering associated with the subscription
  • Fault notification point which will be the first line of support for the customer’s users of GSM-R. This point of contact will receive and, when needed, relay faults to Bane NOR’s Operations Centre which is the second line of support for users, if nothing else is agreed upon
  • Expected number of future subscribers so a reserved number series can be determined

When Bane NORs Operations Centre receives the “Customer Form” the customer is registered in the customer and subscribers system and the customer will be issued a customer number which is to be used for all inquiries concerning the subscription/SIM-card.

All authorized by Norwegian Railway Authority to operate railway functions must register as a customer when they desire a SIM-card to utilize GSM-R. Additional information as to who this concerns, cf. URL-address below5 . In addition Bane NOR departments can order a GSM-R subscription.

If a request comes from a customer outside of what is described above and they state that they have the right to have a GSM-R radio for communication, it must then be ordered by their employer which is either an RU or the unit in Bane NOR they are hired by.

If someone rents a train from outside of the country and the owner is not on Norwegian Railway Authority’s list, the SIM-card can be ordered from NOS by those who are renting the train. The renter must be registered in the system as a customer and the customer who orders a subscription will be responsible for the subscription/SIM-card.

4 Customer form: 5 Applies to:

A customer relationship must first be established between the customer and Bane NOR and then the customer can order a SIM-card to use the GSM-R network.

Changes in customer relationships shall be reported in writing to the Operations Centre (NOS). Ordering/SIM-card

SIM-cards can be ordered either by a new customer or by a previously registered one when for example there is an error on the SIM-card. In both cases “Abonnementskjema” is used”, see URL-address below6 . The form is to be filled out, signed and sent to Bane NOR’s Operations Centre (NOS), see chapter for contact information. Be advised, it takes approximately two weeks for delivery of the SIM-card. Larger orders take longer.

When in need of changes or updating Bane NOR’s Operations Centre (NOS) will update the contents of the user’s SIM-card. The updates will be done either directly via a card reader or over the air via SMS. The updating method is dependent upon whether the SIM-card is physically available or not. With regard to updates that have not been requested by the user, the Operation Centre will contact the user prior to running the update.

Test and Course SIM-card:

NOS also has the ability to loan out special SIM-cards designed for testing and holding courses. The contents of these SIM-cards are slightly different from usual SIM-cards. The use of such test and course cards will therefore not disturb normal users of the GSM-R network. Contact the Operations Centre if you wish to borrow SIMcards for testing or holding courses, see chapter for contact information. Operations Centre (NOS)
