Steering of Roaming Platform (SOR)


 Steering of roaming system enables powerful and flexible network selection management to encourage the “right “roaming network choice for subscribers (Steering of Roaming concept).

Registration procedure control for outbound roamers is  performed in   full   accordance  with   IR-73 that  is main GSMA regulation document related to the  steering services and  allows  the  most efficient deployment of Steering of  Roaming services as well  as influencing  roaming  partners with a view to optimizing roaming agreements  and   providing required quality of service.

Steering   procedure    may     be based on several network selection criteria like network priority, roaming KPI (share of   successful   registrations   or share of unique subscribers registered in particular network, number of various errors), traffic proportions etc. Additionally PROTEI Steering platform is able to solve   a variety   of additional tasks like profile management for outbound roamers (CAMEL Profile deletes or update, remove fraud-risky supplementary services etc). Thus, deployment of PROTEI steering platform efficiently covers many business and commercial tasks related to outbound roaming optimization.

Being integrated with PROTEI Diameter Real-Time Mediation solution Steering platform will be able   to serve LTE traffic and   to deliver steering services for LTE networks.

Gateway Location Register (GLR)


PROTEI Gateway Location Register gives an Operator unique possibility to optimize its roaming connectivity and signaling traffic.   GLR captures all information about inbound roamer’s profile during initial registration and provides this information upon any request from VLR significantly reducing the necessity to interrogate with HPLMN elements. Such approach visibly decrease many risks related to SoR applicability, incompatibility problems, and other similar issues that may finally lead to losing the roamer. Main advantages for GLR deployment are:


- Reducing the volume of signaling traffic between Operator and SCCP-provider.

- Reducing efficiency of SoR systems installed by home Operators due to reducing number of transactions steering can  be applied to.

- Secure roamers retention in Operator’s network (less chance to lose the roamer during interrogation with home network or in case of short- terms failures /minor coverage   problems).

- Full compliance with applicable ETSI standards (ETSI TS 23.119) and GSMA regulation; No violation of any GSMA rules or adding extra signaling (compliant).

- High efficiency for complex or segmented networks.


GLR have powerful and convenient statistics and  CDR generation modules. Web-based administration kit provided with the system contains specialized analytic tools for effective analysis of inbound roaming traffic and its structure.


Key Benefits


- Decreasing the volume of signaling traffic between Operator and SCCP-provider

- Secure roamers in Operator’s network (less chances to lose the roamer during interrogation with home network or in case of short-terms failures /minor coverage problems)

- Full compliance with applicable ETSI standards (ETSI TS 23.119) and GSMA regulations

- High efficiency for complex or segmented networks

Local Number for Visitors


This solution gives Operator the unique innovative functionality to provide local number for long-term business roamers.

The number can be used for accepting incoming calls along with the ability to save activity of the main number. There is no necessity to purchase separate local account.

Roamers save the costs of expensive incoming calls and get more closely to their business    partners because of the “presence effect” (no need to dial international number from the country where the subscriber currently resides).

Operator can use this solution to increase its revenue by deploying new attractive services for inbound roamers and saving traffic in the network.   


Key Benefits:

- Powerful maintenance and reports system

-Horizontally scalable

-Highly flexible

-Routing management

-System voice prompt management

Roaming Assistant


PROTEI Roaming Assistant is a highly effective application for correcting typical dialing errors made by roamers.

It also allows them to access short number services from  their home network while in roaming, leading to  a  significant increase in  the proportion  of  successful calls and increasing Operator's income.

This service can be deployed both for inbound roamers (ISUPbased) and for outbound roamers (CAMEL-based).


Key Benefits


 -Informs subscribers about dialing rules by SMS on misdial

 -Automatic number correction for inbound and outbound roamers

 -Advanced statistic collecting subsystem

 -Home network short codes access for inbound and outbound roamers

 -Subscribers receive information in their native language

 -Increase roaming profits

     SMS Welcome and Roaming Tariff Advisor


PROTEI SMS Welcome system is a very efficient tool for mobile Operators to provide range of services both for subscribers when they are in roaming   in foreign networks and for foreign subscribers registered in the network of the mobile Operator.


”Welcome SMS” and “Bon Voyage SMS” services allow subscribers to receive different kind of information: about the network where subscriber got registered now, about the country, prices for the main services, etc.


The system supports flexible delivery scenario, dynamic content delivery, SMS language management depending on the home country of the visitor, network and subscriber black lists. The system interacts with SMSC via SMPP v.3.4 protocol. PROTEI SMS Welcome increase loyalty   of subscribers and roamers.

Roaming Tariff Advisor can add an extra-value to traditional “Bon   Voyage   SMS” service. This SMS-based service allows Operators to send roaming tariff information to subscribers according their visited   location and prevent the possible risk of losing clients due to “unexpected” roaming costs.


    Key Benefits:

    - Convenient Web-interface

    - Group and individual user options

    - Scenario management

    - Multi-language support

    - "Bon Voyage" SMS functionality

    - Dynamically formed content

Roaming Optimization Suite


Roaming Optimization Suite is a powerful system, consist of 2 subsystems: PROTEI Roaming Optimization and Visitor Retention Subsystem.


PROTEI Roaming Optimization is an efficient solution that helps to save traffic in the network for calls between two subscribers from another country decreasing cost for roamers and increasing Operator’s revenues. To call another person registered in the same network, using “optimal route”, the foreign subscriber should dial the destination number with special prefix.  The  systems checks location of the  called subscriber and   if  he/she  is  found  in  the same network, the system makes call  using optimal routing rules without  creating a voice  loop  via roamers home network.

Visitor Retention Subsystem is targeted to increase Operator’s revenues from inbound roaming services and implements actions targeted to visitors’ retention.  The system ensures that roamers do not leave the network due to momentary communication problems like loss of coverage etc. It uses standard MAP Update/Cancel Location procedures to interface with the HPLMN and retain the roamer.


All subsystems of PROTEI Roaming Optimization Suite have powerful and convenient statistics and CDR generation modules. Web-based administration kit provided with the system contains specialized analytic tools for effective analysis of roaming traffic and its structure.


Roaming Optimization Platform solves the following tasks:


  • Network selection management for outbound roamers (Traffic Redirection/Steering-of-Roaming concept)
  • Network selection management for inbound roamers (Steering Bypassing, Visitor Retention)
  • Subscriber’s profile management

Multi IMSI Roaming Gateway


Multi IMSI Roaming Gateway is  intended to  expand roaming geography for MVNO,  small and/or independent mobile Operators (named Roaming Clients) by using roaming agreements   and subscription of well-established mobile Operators (sometime named Donors or Roaming Brokers).


Basing on PROTEI Multi- IMSI Roaming Gateway either traditional dual-IMSI roaming services or   innovative dynamic multi-IMSI roaming services may be deployed in optimal way. Multi-IMSI roaming allows providing alternative roaming services for GSM/UMTS network subscribers by using dynamically loaded alternative subscriptions of the visited Operator (guest network). This  solution makes it possible to provide a local number and  access to  all local  services for  the  roamer who  will be  able to enjoy  cheap or free local incoming calls,  cheap outbound calls   and   attractive data  prices without  losing  the  accessibility of the roamer at his/her main phone number.


Key Benefits


-Wide range of supported roaming services

-Powerful maintenance and logging system

-Scalable according to network growth

-Flexible system configuration

-Proven reliability

-Supports all range of services – voice, SMS, GPRS (data)

Boarder Roaming Gateway


As  a   general  rule, subscribers do not proactively change networks during their stay, but in reality,  the  existence of  blind spots, or temporary  problems with coverage or  particular cells congestion, which may occur in any operator’s network, when coverage momentarily disappears or communication services become unavailable, causes  roamers  to   look   for   a new  network. As a result, along the  borders of the  home country, subscribers may occasionally roam on a neighboring country’s mobile network, where  roaming rates/international  call   charges are applicable.

To avoid possible claims, increase level of services, enhance customer care and reduce potential cost and losses for the home network operators and subscribers, the home networks would prefer to retain their customers in such situations.


PORTEI Border Roaming Gateway (BRG) is a platform that provides mobile Operators the   ability to prevent their own subscribers from accidentally roaming on a foreign network while    still within their home country/zone. Using the system helps to avoid possible claims, increase level of QoS, enhance customer care and reduce potential cost and losses for home network Operators and subscribers.

Voice Quality Control for Roamers and SIM Box Detection


Voice Quality Control system allows operators to automatically test speech quality in a simple way for meeting customers’ needs and organizing KPI’s. ITU-T-based speech pattern comparison and   quality estimation according with P.862 ITU-T   Recommendation is performed in the system. Additionally to voice quality testing this platform allows verifying transparent CLI transition between Operator’s network and the network of roaming partner.

The system also supports SIM Box detection functionality for comparison of CLI information sent by the calling party and the one received by called party. SUP-based and CAMEL-based methods for CLI verification are supported.
