2. STRUCTURE OF THE DATABASE The following information is stored in the GSM Association Roaming Database for each operator: • The name of the operator. • The technology and the frequency of the operator. • The operators home country in abbreviated format. • The E.164 Country Code (CC) and National Destination Code (NDC) of the MSISDN

number. • E.212 Mobile Country Code (MCC) and Mobile Network Code (MNC) of the IMSI number. • The E.214 Country Code (CC) and Network Code (NC) of the Mobile Global Title (MGT). • The SS7 international Point Code (PC) used by the (two) international gateway SCCP

node(s) the PLMN is connected to. • The signature of the (two) international gateway SCCP node(s) the PLMN is connected

to. • The type of exchange used as the (two) international gateway SCCP node(s) the PLMN

is connected to. • The initial access solution to the international SS7 network. • The possible subsequent access solution to the international SS7 network. • The possible date for changing between the initial and the subsequent access solution to

the international SS7 network. • The date for the introduction of the ability to transmit and handle XUDT/XUDTS. • The information concerning the availability of White Book SCCP in the PLMN. • Whether ETSI or ANSI SCCP is used by the PLMN for International signalling

connections • The information concerning introduction of MAP, a list of the Application Context with the

current version and the time planned for changing to the next higher version. • Information associated with GPRS network identifiers, such as APN operator identifier,

list of test APNs, Data Service supported with Class Capabilities etc. • Information associated with IP Roaming and IP interworking towards the GRX provider,

such as DNS IP addresses/names (primary and secondary), IP address range(s), AS Number etc. of the PLMN.

• CAMEL Application Part (CAP) version • MMS Inter-working Information The information related to Subscriber Identity Authentication for Roaming subscribers • At the commencement of GSM service • In case of GPRS • A5 algorithm version in use



The subscriber-numbers which will be used for Automatic Roaming Testing, (Ref. PRD IR.28 and IR.29) • All SMSC GT addresses • MSC and VLR addresses with Time Zone information • In addition a free text field is included in order to give more detailed data on

miscellaneous type of information as e.g. more detailed number information, name of contact persons etc.

3. REPORTS Three types of reports are available: 1. Partial Report 1 – with the following information:

• The name of the operator • The home country of the operator • The E.164 CC + NDC • The E.212 MCC + MNC • The E.214 MGT • This is the data relevant for all Visiting MSC/VLRs.

2. Partial Report 2 – with the following GPRS/IP-Roaming & IP-Interworking: • APN operator identifier • DNS IP address (primary) • DNS IP address (secondary) • Inter PLMN GSN backbone IP address range(s) and ASN. • ASN assigned to operator

Note: Production of this report has yet to be agreed with the GSM Association. 3. Full Report 3 – including all the data stored for the PLMN

4. PROCEDURES FOR UPDATING THE DATABASE When data for a PLMN changes, or when a new PLMN is introduced, the procedures for updating the Roaming Database and for distributing the information to the other PLMNs are as follows:

1. The PLMN sends the updating information to the GSM Association Headquarters together with possible information on the date for the change. For this purpose the form given in Annex A shall be used.

In case of a new PLMN: all fields shall be filled in.

In case of a change in data for an already registered PLMN: only name of the operator and the changed data shall be filled in.



Annex B defines the procedures and timescales for a PLMN to send information about a change of data to the GSM Association

2. The GSM Association Headquarters updates the relevant parts of the database.

3. The GSM Association Headquarters can distribute details of the changes to all the PLMN operators. Annex B defines the procedures and timescales for the GSM Association Headquarters to distribute update information to GSM Association Members

4. Headquarters – the IR.21 information for each operator is available on the GSM Association’s Infocentre database. A nominated contact from each PLMN operator can make changes to update the information on this database for their respective network only. Note: The “Miscellaneous Roaming Info” section should be used to identify the fields where changes have been made, with details of the date when they will become effective.

5. The GSM Association Headquarters will investigate to ensure that whenever any change is made by a PLMN operator to the IR.21 database on the Infocentre, all the other PLMN operators will receive automatic notification that a change has been made to that operator’s IR.21 information. Details of the actual change will not be included in this notification. The other PLMN operators can then either view the change detail by accessing the IR.21 database on the Infocentre, or directly contacting the respective PLMN operator.

The required time schedule for updating the database is specified in Annex B.

For roamed subscribers (at the commencement of GSM service) authentication is to be performed at every occasion of:-

a) Network access using IMSI

b) Location updating involving VLR change

c) Network access for at least 1 in x mobile originated and terminated call set-ups (incl. SMS). The value of x will be defined in the roaming

agreements and should be less than 10

d) Supplementary service operation outside call

e) Cipher key sequence number mismatch

If GPRS is supported, authentication is also to be performed at every occasion of:-

a) GPRS attach

b) routing area updating involving SGSN change

c) PDP context activation

MOBILE APPLICATION PART (MAP) Introduction of higher supported MAP version Please note the following when completing this table: If a different Application Context version is supported by multiple vendors of the same equipment in your network then the entry in the table shall be the highest, common AC version supported (e.g. if equipment from one vendor supports an ACv2 and the same equipment but from a different vendor supports an ACv3, then the entry in the table will be ACv2). All operations for an Application Context version must be supported, otherwise that version cannot be claimed to be supported. If an Application Context is not supported, then a single hyphen ("-") shall be entered instead of a number. All GSM Operators shall ask their Vendors to have the latest Version of Release implemented (e.g. Suppose that Ext-QoS-Subscribed length range is 1 to X in ver x.y.z, but 1 to Y in the latest MAP version of the same release. In this case, all operators shall implement Ext-QoS-Subscribed length range as 1 to Y as written in the latest version).

Vendor Information BSS vendor(s) and SW/HW version:

14 The MSC is acting as a VMSC for a roaming subscriber for ORLCF; see sub-clause 4.2 of 3GPP TS 23.079 for more information.

15 The "locationInfoRetrieval" application context is only valid for inter-PLMN signalling in Optimal Routeing of mobile-to-mobile calls; otherwise it is only

intra-PLMN. Note that the dialogue initiator is a GMSC which is integrated with the calling subscriber's MSC/VLR (and obviously the dialogue responder is the

called subscriber's HLR, which is in the called subscriber's HPLMN).

22 IP addresses or IP address range(s) of all operator's nodes that connect to the inter-PLMN IP backbone network known as the "GRX" e.g. GGSNs,

SGSNs, MMSCs, AAA Servers/Proxies, DNS Servers etc. This information is used for firewall and Border Gateway configuration (see PRD IR.34).

23 The Autonomous System Number (ASN) is a 16 bit integer that every PLMN must assign to their IP network that is seen as one Autonomous System (AS).

The ASN enables the exchange of exterior routing information between neighbouring Autonomous Systems. This can be either a private ASN (64512 through

to 65535) or public ASN.

24 IP address(es) and name(s) of DNS server(s) that are authoritative DNS server(s) i.e. DNS servers that answer DNS requests/queries from local caching

DNS servers. Note that DNS hostname(s) given in this field should match the actual name(s) configured in the operator DNS server(s) (this is to avoid conflict

with the NS records in the Root DNS and operator DNS servers).

25 IP address(es) and name(s) of DNS server(s) that are local caching DNS server(s) i.e. DNS server(s) that send DNS requests/queries in order to resolve

domain names on behalf of e.g. SGSN, MMSC etc. Note that DNS hostname(s) given in this field should match the actual name(s) configured in the operator

DNS server(s) (this is to avoid conflict with the NS records in the Root DNS and operator DNS servers).

26 Pingable and traceroutable IP address of a node within the operator's AS. Maximum size for ping is 64 bytes. Minimum time interval for pinging is 1 hour.

29 Brand name of the Home WO WLAN service seen by the end user in the web based login page. The brand name can be used to mask the realm from the

end user in web based login pages e.g. by utilizing a dropdown box into realm known by the network. This enables an operator to change its roaming realm

with reduced impact to the user experience. If the operator has multiple roaming realms they have to be mapped one-to-one to brand names.

40 This field is not a part of the database and is only used by the HQ when distributing updating information.



The general updating procedures for information in the roaming database are described in section 4 of this document. The following schedule shall detail these procedures with regard to the single parts of information. The different fields contained in the database are of different importance to the operation of the GSM networks. Hence, the time schedule of sending the information about a change of data to the GSM Association Headquarters (GSM Association HQ) and the delay until this information is distributed to the other GSM Association members may depend upon the single case. Details of any changes will be sent via email. Update Intervals The intervals for updating of information shall be as follows:

1. Name of Operator/Operator’s Home Country (abbreviated): Impact:

Changes to a name of the operator are only critical to the administrative parts of GSM relationships. New operators joining the GSM Association should be introduced as soon as possible.

Update to GSM Association HQ:

As soon as possible with date when the change will be valid or the new member will start service?

Distribution from GSM Association HQ to GSM Association members:

With next full update (if before date of change), otherwise at least 2 weeks before change.

2. E.164 CC+NDC of the MSISDN: Impact:

Information critical to operation of International Roaming connections. New or changed data have to be implemented in the switches.
