Alerts are transmitted to subscribers to an alerts service in response to
events that occur within a gaming environment. Communication within the
gaming environment is limited to specific game consoles and the gaming
service. A subscriber to the alert notification service can be alerted
when a friend joins the gaming service to play a game, or can select
other events for which an alert is requested to be sent to the
subscriber. In response to any predetermined event occurring within the
gaming environment, an alerts service provides an alert or message that
is transmitted through a secure firewall and outside the gaming
environment. The alert message can be in the form of a pop-up that
appears on a user's instant messaging service, or an email, or a message
that is transmitted through a mobile communication service to a cell
phone or other portable communication device.
