With proficiency in information technology and business processing since 1997, Comfone isthe only independent clearing agent in the market without ties to specific network operatorsor groups.

1.2 Purpose and Scope

This document describes Comfone Data Clearing (DC) Service for roaming traffic, withspecific references to the processes and workflows performed by Comfone DC OperationalTeam with the support of dedicated data clearing systems

Comfone DC Service is provided fully in accordance with the standards set by the GSMAssociation as defined in the relevant Permanent Reference Documents (PRDs).

Customised solutions outside the standard DC activities can also be supported, asapplicable.

1.3 Comfone Clearing Unit

Comfone operational clearing environment is operated by Comfone Clearing Unit and it is

built on Comfone IT infrastructure.


7/22



Comfone DC Service is operated by the DC Operational Team of the Comfone Clearing Unit,the DCH Help & Support Centre, based in Switzerland and consisting of well experienced DCCoordinators, who will execute all the required DC activities on behalf of the DC Customer ashighlighted in this document.

The following diagram depicts the logical organisation of Comfone Clearing Unit:

The Operational Teams of the Clearing Unit operate and supervise the specific systems andprovide the required support, in accordance with the applicable GSMA standard proceduresand interfaces.

All Clearing systems are designed, developed and maintained internally. Furthermore, theyare based on the newest IT infrastructure.


8/22



Comfone DC Service is a comprehensive outsourcing solution to manage the roaming trafficexchanged with your roaming partners.

Designed to fully support the GSMA standards, Comfone DC Service perfectly integrates

with Comfone Financial Clearing Service and can also work in combination with other FCAproviders.


9/22



2 Data Clearing features

Comfone Data Clearing service is flexible and consists of a set of features, basic andoptional, that can be combined to create a customised Clearing Service Package to fullysupport the specific needs of the Customer. Swiss precision is what we aim to provide.

3 Communication link to Comfone Data Clearing Platform

Comfone will take the lead to set up and test the communication link between Customer andComfone DC Platform. Comfone is responsible for setting up, testing and operating all therequired communication links to exchange files with the Customers roaming partners.

With reference to the interface between the Customer environment and the Comfone DCplatform, Comfone recommends to use a site-to-site VPN solution via the Internet, as

described in the following picture. This offers a maximum of security and reduction incommunication costs.

Access device: VPN Router (IP Sec)

Protocol: IP Sec, FTP, ICMP

VPN Parameter(s): Provided by Comfone

Additional transfer mechanisms can also be supported when requested by the Customer.

The same communication links can in principle be used for exchanging different types ofdata streams, like TAP, RAP, NRTRDE, etc, including the raw CDR data feed required tosupport the TAP Creation feature, when required.


10/22



4 DC features related to TAP Out / RAP In process flow

The following features are available in the TAP Out / RAP In process flow:

4.1 TAP File Creation (Optional feature)

Comfone supports TAP creation based on the available customers in-house file formats asgenerated by the network or mediation device.

Comfone collects the input Call Detailed Records (CDRs), groups them by roaming partner(HPMN), ensures that the correct handling of the file transfer schedule applies and checksthat no file will exceed the maximum allowed size.

Upon completion of this mediation task (collection, aggregation, etc.), the input CDRs are

then submitted to the TAP file generation process, where each resulting call event detail willalso be rated. To this extent, the TAP File Rating feature is used (described later on in thisdocument).

4.2 TAP File Pre-fetch (Basic feature)

This is the first step of the TAP Out process, consisting of the initial upload and pre-processing of the TAP File. At this point in time all relevant TAP File data as provided on theprivate interface are stored for reporting.

4.3 TAP File Validation (Basic feature)

All TAP files flowing through the Comfone DC platform are subject to data validation.


11/22



Comfone validation engine supports all standard validation rules defined by TADIG andallows very flexible configurations.

For example, on Customers request, each particular roaming destination can be configuredwith a specific set of validation rules to be applied to the related files.

4.3.1 IOT Check (Basic feature)

Amongst a set of Data Validations, Comfone verifies that the applicable IOT has been usedto consistently and correctly rate each call event detail included in all TAP files.

IOT Check applies by default to all roaming traffic and it is configured according the IOTinformation provided by the Customer as applicable for each specific roaming partner.

4.3.2 Exchange Rate Check (Basic feature)

Comfone validates that the execution of the exchange rate conversions in each TAP file iscompliant with the applicable rules defined by GSMA.

4.3.3 Duplicate Check (Basic feature)

Comfone performs a check to detect any duplicate records within the same file and across allfiles for both inbound and outbound roaming traffic, over a 45 days period by default.Different periods can be supported on Customers request.

4.4 Error Resolution (Basic feature)

In case any validation error is detected on Customers TAP Out files, Comfone will apply a

specific error handling procedure, where the actions to be taken depend on the category theerror belongs to (Fatal, Severe and Warning).

Comfones quality policy is to minimize the number of errors that are transferred via TAP tothe Customers roaming partners.

To achieve this, errors detected in TAP Out files received directly from the Customer can betreated in different ways, according to the Customers requirements.

Comfone can undertake one or more of the following actions, as applicable:

By-pass the errors (as an exception or permanently), for a specific roaming relation.

Correct the errors, when possible

Execute a "drop" operation, eliminating records affected by "non-correctable" errors

In case a drop operation is executed, notify the Customer by means of reports or (whensupported) by means of the Reject & Return Process on the private interface.

Please note that error corrections are intended to be an exceptional process, as the intentionis that the Customer has implemented and tested its own TAP environment and thereforecan provide the proper quality level. Should this not be the case, Comfone recommends toimplement specific optional features (for example TAP Creation), or to define togethercustomized solutions, when applicable.


12/22



4.5 RAP File Generation & RAP File Exchange on private interface (Optional

features)When requested and supported by the Customer, the Reject & Return process can also beused on the private interface between Comfone and the Customer to report errors detectedon TAP files received directly from the Customer or to forward errors received in RAP Filesfrom Roaming Partners.

4.6 TAP3 Conversion (Optional feature)

When requested by the Customer, Comfone can provide the required conversion between allTAP3 release versions to make the Customer compliant with the applicable formats, asagreed (implicitly or explicitly) with each of the Customers roaming partner.

Release version of converted TAP Files can be defined at roaming connection level.

4.7 CDR Merger (Basic feature)

Repaired CDRs, previously rejected by Roaming Partner, are merged automatically into nextavailable TAP Files. The results of this process are stored or reporting.

4.8 TAP File Rating (Optional feature)

The TAP File Rating feature allows to rate all call events with a high degree of flexibility andallows the implementation of any IOT (inter-Operator Tariff) the Customer may want to applyto each individual Roaming Partner:

Different, fully configurable charging principles.

Destination based tariffs (number analysis).

Rating for different regions and special numbers (for example Premium RateNumbers).

Different destination definitions for different services (for example unique zone forSMS, different zones for voice).

Location based tariffs, based on analysis of subscriber location

Support for day category and time band.

Setup charge (Fixed one-off).

Duration or volume based charge.

Currency conversion.

Traffic class (GPRS).

Calculation of applicable taxes, including support for partial taxes based on Air Time /Toll charges, Tax on Tax and location based taxation.

Different IOTs can be implemented for different roaming partners, thus every roaming partnercan be treated differently from a rating point of view.

Special rating requirements from the Customer can also be implemented on request asoptional feature.


13/22



4.9 Number Formatting (Optional feature)

The number formatting feature can be associated with Rating (Comfone uses the formattedcall destination to calculate the charges for the records) or applied independently to generateinternational representation of the called/calling number based on the applicable scenario.

There are various types of call number related services available:

number formatting

special number marking

short code processing

SMSC number correction

CAMEL destination formatting

4.10 TAP File Verification & TAP File Correction (Basic features)

Any TAP File flowing through the DC System might have been subject to modification afterthe initial validation performed when received from the Customer and according to thespecific configuration parameters applicable to that specific TAP File (for example, TAP FileRe-Rating or TAP File Standard Conversion). Consequently, the TAP File is validated againbefore forwarding it on the public interface, thus any possible error will be detected andcorrected.

4.11 TAP File Information Collection & TAP File Forwarding (Basic features)

As last step of the TAP Out process, the relevant information of the TAP File, including FileDelivery Log, are stored for reporting purpose and the TAP File is forwarded to the RoamingPartner (or its DCH) on the public interface. An automatic File Re-transmission will betriggered in case of detected transmission failure.

Please note that in case the Roaming Partner also uses the Comfones Data ClearingServices, the TAP File will physically leave the DC System and it will be re-entered as inputto the TAP In process as it would have been received on the public interface from a RoamingPartner or its DCH.

4.12 RAP File Pre-fetch (Basic feature)

In the event that a RAP file is received from any of the Customers roaming partners,

Comfone will upload the incoming RAP file into the DC platform and an acknowledgementfile will be sent out to the roaming partner, as applicable.

This is the first step of the RAP In process. At this point in time all relevant RAP File data asprovided on the public interface are stored for reporting.

4.13 Handling of reported errors in RAP In Files (Basic feature)

Comfone will check the correctness of the received rejections by validating the RAP In Fileand will follow up as applicable, depending on the type of error claimed to justify the rejectionand any invalid rejections will be disputed as described hereafter.


14/22



4.13.1 TAP File Re-sending (Basic feature)

In case any missing TAP File has been reported by the RAP File, Comfone will follow updepending on original file availability:

If TAP File Available, TAP File Re-Sending Process is automatically triggered

If TAP File is not available (i.e. never received from Customer), the issue is alreadyknown due to internal file tracking process. In this scenario, Notification File can begenerated on Customers request

4.13.2 Fatal RAP Handling (Basic feature)

In case a Fatal Error has been reported by the RAP File, the validity of Fatal Error reported ischecked by DC Operational Team.

Valid rejects will be repaired by DC Operational Team and the repaired TAP File will beforwarded to Roaming Partner. Invalid rejects will be disputed.

4.13.3 Severe RAP Pre-process & Severe RAP Handling (Basic feature)

In case Severe Errors have been reported by the RAP File, the content of the RAP File iscorrelated to the original CDRs sent out in the corresponding TAP File on public interfaceand the validity of each Severe Error is checked by DC Operational Team.

Invalid rejects will be disputed.

Valid rejects will be treated according to Customers requirements in one of the followingways:

CDRs will be repaired by Comfones DC Operational Team and forwarded to RoamingPartner by merging them into the first subsequent TAP File

CDRs will be forwarded to the Customer by means of RAP File on private interface orcopy of the original RAP File

4.14 RAP Dispute Process (Basic feature)

Any invalid reject will be disputed by DC Operational Team according to Dispute &Escalation Process defined by GSMA

Customer involvement may be required in case dispute cannot be resolved, e.g. lack ofcooperation on roaming partners side
