A1S Event

Day-to-day service provision causes mobile network operators to accumulate a large body of data on consumer behaviour of the subscribers. Analysing this data allows for personalised offers, custom-made for each individual subscriber. The effectiveness of such offers depends on whether the communication is well-timed and the tools well-chosen.

A1S Event is a solution for managing personal marketing communications utilising the data on consumer behaviour. Promotion of services and tariff plan add-ons are offered precisely when the subscriber is most  interested in it. The tool of communication is an interactive message mediated by A1 Systems’ own A1S NaviSIM applet.

A1S Event constantly analyses the data on every subscriber in real time. The solution can be pre-set to detect specified events. As soon as the solution has detected a specified event, it sends an interactive message to the subscriber. The content of the message is determined by the context of the event. In one or two clicks, the subscriber is able to accept the offer, receive additional information or decide between several tariff plan options.

The solution is capable of analysing subscriber behaviour and detecting relevant events on its own. It can also receive the necessary information on event occurrences from any other systems used by the Mobile Network Operator.

A1S Event enables the MNO to effectively promote its own, as well as partner services and manage customer life cycle, achieving reduced churn.

Examples of events and the corresponding contextual offers

Event Offer
Mobile data quota is over before the end of a billing period. Offer an additional quota.
A certain number of phone calls to some destination for a specified period of time has been reached. Offer a tariff plan option for that type of calls to the subscriber.
The subscriber has run out of phone credit. Right after the failed phone call, display a dialogue box advertising services to enable further phone calls.
A subscription is likely to be cancelled soon. Make a particularly attractive offer on all or select communication services to retain the subscriber


A1S Event uses the A1S NaviSIM applet for interacting with the user. The solution also can work with another DSTK through the aproproate service platforms of their vendors.

The server side of the solution is based on the A1S MCS platform. Advertising campaigns are managed through a user-friendly, intuitive Web graphical user interface to enable the user:

  • set up contextual events,
  • assign different messages to different subscriber segments in connection with the same event,
  • track and manage advertising campaigns in real time.
