Egyptian Operator Improves Inbound Roaming Retention
Over the past few months, Egypt's Mobinil contracted Astellia to identify weak roaming areas and to improve roaming retainability and efficiency on its network in preparation for this summer's tourist season. The Astellia team used Astellia equipment already installed on Mobinil network to capture and process the huge amount of data. Using roaming KPIs, it identified Loss of Roamers and potential subscribers' retention weaknesses mainly in touristy and coastal areas (Sharm, Urgada, Luxor, etc.).
By correlating MAP and A interface information, applying adequate filtering and aggregating several days to get accurate measurements, Astellia listed the top Roaming Loss cells for which radio conditions were evaluated using Cigale detailed results. For instance, it made obvious the lack of roaming agreements with some other operators or it identified Outdoor/Indoor Bcch interferences in large tourist estates.
Mobinil Radio teams then took the necessary actions to correct the highlighted problems.
Mr Mohamed Ali Moussa, Roaming team manager, says: "Measurements made in May vs November showed an increase in the number of new roamers on the observed area: from ~26500 to ~31150. The roaming traffic increased 3 times more than the number of new roamers on the same period, whilst the roaming loss value on top LOR cells decreased was nearly divided by 2."
