External Access to Transporter to Report Events

Hi EM Gurus,

I have a scenario where certain events will be reported by the transporters agent.The client requires the same to be

done on client portal.

The expectation is, an alert will be generated for the predecessor events to notify the transporter to report the event as & when it occurs,the alert will have a direct link to the portal.Clicking on which the event management reporting screen will be displayed on the transporters default internet browser.

How can this be done.Any suggestions
