Introduction International Roaming

• In Roaming :- Subscribers of foreign Operators

roaming in BSNL mobile network

• Out Roaming :- BSNL Subscribers roaming in foreign

' .

• An Operator wishing to launch International Roaming

facility should have agreements with large number

foreign mobile operators world wide ( Ideally all ).

For internal circulation of BSNL only




• Agreement should be Bilateral so as to have both In &

Out Roaming.

• Money is to be collected by an Operator from the other

’

subscriber in his network. As such Agreement is required

with each Operator individually.





• As such BSNL should have 850 X 21 agreements and

850 X 21 set of testing etc. Which is practically

Impossible.

• ,

Roamware, USA.

• This basically enables to have one nodal network in

BSNL and all the remaining networks can piggy back on

the nodal network.





• W.B.Circle is the nodal circle in BSNL and all other

BSNL networks piggy back on W.B.Circle for

International Roaming.

•

testing with the foreign Operator for whole of BSNL

instead of 21 agreements and 21 sets of testing.





• Launching Roaming with a foreign Operator is a

time consuming process involving :-

• Negotiating and establishing Roaming agreement

signed copies and supporting documents.

• IREG (Interworking Roaming Expert Group)

(Technical )





• TADIG ( Transfer Account Data Interchange Group

) (Billing) testing between networks after exchange

of SIM cards. Exchange of test certificates after

.

• Seeking RBI approval for net settlement with

foreign operators in Foreign Currency.

• Deciding date of Launch and exchanging signed

copy of launch Letter.





• Enable roaming in SRS / RBS, Coordinate with

billing centers for configuration.

• Billing centers to in turn coordinate with each MSC

.

• Since BSNL did not have roaming agreement with

any foreign Operator and the same is a time

consuming Process.




BSNL Strategy

• BSNL launched its International Roaming facility

by Piggy backing on M/s Spice Punjab ( A CMTS

Licensee in Punjab – A Modi Group Co.) w.e.f.

. . . .

• Initially BSNL deployed DUAL IMSI (International

Mobile Subscriber Identity) SIM card for the same ,

but now use Triple IMSI card.




BSNL Strategy

• While within India, Subscriber Selects Home IMSI

and while abroad he selects Dummy IMSI of

Sponsor Network. The same is done in the

-

• Insert the BSNL International Roaming SIM card in

the mobile handset and Switch on the handset.

• Go to Cellone menu and select it.




BSNL Strategy

• Then go to Network menu under Cell one menu

and select it.

• Finally select International Option out of the two

, .

• By doing so the subscriber selects

W.B.circle/cellone (sponsor) like IMSI and makes

the foreign Operator feel that he is a W.B.circle

BSNL Subscriber. All other circles of BSNL piggy

back on W.B.circle .




BSNL Strategy

• Mobile facility would be available through this

option only while abroad. While within India, this

setting should be kept as National in general.

•

facility should be verified otherwise it may result

in fraud due to delay in receiving Usage value/

Billing Information of Out-Roamer




BSNL Strategy

• BSNL is also simultaneously establishing Roaming

Agreements with foreign operators directly and

launching Roaming with Foreign Operators via

. . .

• Although the Agreement and Testing for direct

agreements is Bilateral, BSNL using these

agreements for In Roaming as well as out Roaming.




BSNL Strategy

• In Case of direct agreements W.B.Circle is the

nodal circle and all other circles piggy back on

W.B.Circle,the SIM card for Roaming abroad would

. . .

• This would require TRIPLE IMSI SIM Cards. i.e. a

SIM card with Home IMSI(National), For

International Spice like IMSI ( Earlier Sponsor ,not

Used now) and W.B.Circle like IMSI ( Sponsor,Used

now only).




BSNL Strategy

• Note :- As per orders of GOI :-

• Presently Subscribers of foreign Operators not

Permitted to Roam in Assam, J&K and N.E.

• ,

areas can Out Roam in foreign operators network.

• Financial Settlements with Foreign Operators is

done by West Bengal Circle for whole of BSNL.




Silent Aspects

• Around 70% revenue is from In Roaming.As such

efforts should be made for maximizing In-Roamers

in BSNL Network. Very effective way for increasing

.

• Criteria of selection of network adopted by

Handset:-Almost 100% of In-Roamers use

automatic selection mode and not manual selection

mode as they are not bothered about the network

they log on to.




Silent Aspects

• On switching on, Handset scans all networks

available.

• Checks which of them have signal level Greater

- .

• Checks if any one of them is the network in which

he was previously logged on to , If yes then logs on

to that network, Or else logs on to any one signal

better than -85dBm.




Silent Aspects

• In view of above, it is vital to have optimum Signal

level of BSNL mobile network at all entry points

like Roads and Airports and at those places

.

• Check this with Test SIM cards of foreign

Operators / MTNL in automatic mode.




Silent Aspects

• Problems of Out Roamers :-

• -List of Countries and Networks where In Roamingis Available – Refer BSNL INTERNET Website –

• Coverage Map of Operators to know if coverage of

an Operator with which Out Roaming Possible via

BSNL SIM Card is there in a given town / city. –

Refer :www.gsmworld.com website – GSM Roaming

section – Coverage MAP




Silent Aspects

• Frequency of handset should be Compatible in

Foreign Operator’s network. Check website for freq.& model No.

•

W.B.Circle and only after checking if Billing Center

has configured the same.

• If configuration is not there in Billing Center then

CDR will not be rated and would go into MIU.




Silent Aspects

• Whenever, a new network element is Introduced in

BSNL network it is essential to have configurationfor the same in SRS (Signalling Replicator System)

.

The same would be done by W.B.Circle.

• Each network element has GT ( Global Title –

same as MSISDN Number)




Silent Aspects

• For piggy backing on the network of

W.B.circle/BSNL a dully GT needs to be defined forthe network element so that the network element of

with the network element of W.B.circle/BSNL.

• Time frames for sending TAP files to foreign

Operators every 6 hours including for CDRS in MIU

( Message Investigation Unit ).




Silent Aspects

• New MSCs should be put in commercial operation

only when they are able to automatically sendCDRs to billing center.

•

Roaming rated CDRS to W.B. Circle.

• In case for direct agreements (W.B. circle/BSNL),

Clearing House in this case is M/s MACH.




Silent Aspects

• In case TAP files do not reach the foreign Operator

24-36 hrs they are liable to be rejected and nopayment made to the VPLMN.

•

Reports ). Each Operator has its own threshold for

HUR ( suspected fraud ). Clearing house will send

HUR to HPLMN based on the criteria of the HPLMNfor usage beyond the threshold in the VPLMN by

an In –Roamer.




Silent Aspects

• HUR report should reach the foreign Operator

within 36 of last call of HUR being made.• Billing Centers are also required to pursue with all

by them have been accepted by the respective

foreign Operator.

• SDR ( Special Drawing Rights) is a non realcurrency. Rate published by IMF, Rating on the

basis of rate on 23rd of the preceding month.




IR Agreement Document

documents are as follows :-• AA 12 :This is the basic legal framework document

,

inter-alia, defining law with which the agreement

would be governed, period of validity, liabilities of
