Control Roaming Quality and Partner Network activities to increase revenues with the most comprehensive solution available on the market

Many Operators have growing numbers of roaming subscribers and need to protect and increase their roaming revenues. With many visiting customers and their own customer roaming abroad, roaming management departments look to deploy on-line monitoring tools and roaming intelligent systems to assure quality of international roaming service and capture the growing roaming traffic revenues.

The functional area of particular interest is VIP (High ARPU) customer management, including the possibility to define alarms and reports for particular inbound roamers. Another area is the steering of roaming, the process by which a mobile operator decides which partner their subscribers will use whilst roaming. Operators want the possibility of identifying steering of roaming activities and roaming service issues to capture and respond to new roaming trends with partner networks.

Nexus Telecom with the Cellusys alliance enables operators to receive the most comprehensive portfolio of roaming management solutions available in the market. Nexus Telecom’s expertise in monitoring and testing, coupled with Cellusys’s active signaling expertise for signaling management, allow implementations to perform in any network topology. The complementary nature of the alliance means that significant advances can be made, and the data shared can be turned into valuable roaming management information.

Roaming Service Monitoring

Nexus Telecom’s NexusNETVIEW Signaling Intelligence Monitoring System, with its International Roaming Management Application (IRM), monitors roaming service QoS inbound and outbound, as well as detecting Steering of Roaming. For VIP customer management, the Subscriber Monitor App is an on-line VIP service quality monitoring system delivering instant feedback if these important customers experience poor access connection to roaming services.

NexusNETVIEW solution provides benefits including:

  • For Marketing – What are the important networks/countries for our VIPs and subscribers?

  • For Planning – To which network/country do we have international capacity issues?

  • For Operations Center:

    • Do we have data service connectivity with roaming partners?

    • Can our Outbound Roamers receive voice calls and use the SMS service?

    • Do we have voice call, data and SMS service issues for inbound roamers?

NexusNETVIEW IRM provides online Call Data Records (CDR) for international signaling roaming services and VIP customer service monitoring.

Steering of Roaming (SoR) and Roam intelligence

For members of Global Alliance Networks, network operators must keep their roaming subscribers on the partner networks. However, often they need an additional solution to measure and report statistics, including:

  • Success-Rate of Preferred Networks vs. Non-preferred Networks

  • Trend-Analysis of SoR Success and immediate recognition of new trends in SoR

  • Tecognition of SoR Procedures Applied

  • Identification of SoR Methods by different Operators

  • Identification of Lost Roamers due to SoR

  • MAP Statistic Reports on Inbound SoR Manipulation:

Nexus Telecom’s partner for Roaming Intelligence, Cellusys, provides Roam Intelligence (RI). The Roam Intelligence (RI) system is responsible for reporting on the behavior of inbound and outbound roamers on the network, giving accurate network information not previously available. This enables Operators to maximize revenues while establishing, maintaining and controlling roaming agreements with their partner operators.

Roam Intelligence (RI) provides essential analysis for every roaming department, both commercially & technically. RI gives a full overview and analysis with 15+ advanced reports of critical roaming signaling KPIs required to detect unexpected trends, perform network enhancement and maintain customer satisfaction.

The system also provides access to real-time roaming activity, helping operators solve roaming issues for inbound and outbound subscribers. Roaming managers receive a full overview and analysis of all roaming activity with advanced reports combing the customer activity and statistical data points required to perform traffic analysis, protect and increase roaming revenue, and prevent customer churn.

When National Mobile Roaming becomes a conflict of Interest

Mobile Operators are constantly looking to enhance their network coverage in order to attract more subscribers and increase customer satisfaction. These enhancements, however, can be both time consuming and costly   pushing Operators towards National Roaming Partner agreements in order to provide better network coverage. By having these agreements in place, Operators are able to provide service to their subscribers in geographic areas they currently cannot reach or are commercially impractical.

Although this can be a beneficial solution for mobile operators, it can cause a conflict of interest in some of their serving areas. Described below is a challenge that one of our clients faced recently and requested Cellusys to implement a solution for this problem:

Our client is a major operator in a large country, which has put in place multiple national roaming agreements with other national operators in order to provide better network coverage to its subscribers.

They noticed that their national roaming partners were expanding their network coverage to overlap their home network coverage area either by adding more base stations or increasing transmission power. This greatly increased the chance of their subscribers registering on the roaming partner’s network even when they are in the home network coverage area. This has resulted in millions of dollars in lost revenue every month to our client.

National roaming agreements tend to be revenue share by nature and require great attention by the home operator on controlling their subscriber roaming activities. Failing to pay attention to this can cause the home operator to face significant revenue losses while their national roaming partners profit significantly.

Basically operators need to control their subscribers roaming activities when moving around following coverage areas.

  1. Home Network Coverage Area Only
  2. Home/Roaming Partner Coverage Area
  3. Roaming Partner Coverage Area Only

Operators can successfully achieve this by incorporating the Cellusys National Steering System into their network which prevents subscribers from registering on the national roaming partner’s network where there is coverage overlap and re-directing them to the home network when the home network becomes available again. In a nutshell Cellusys National Steering enables the home operator to gain control of their subscribers when roaming in partner’s network coverage to ensure that the national roaming partners are only utilised where needed.

Cellusys has implemented National steering successfully for several operators worldwide to help them visualise their national roaming landscape and minimise revenue loss to their national roaming partners.
