Mobile IP notification

摘要

A home agent and a mobile terminal communicate to facilitate the home agent becoming aware of whether the mobile terminal is notification capable meaning the mobile terminal is able to receive notifications of specified events without an open browser window. If the mobile terminal is notification capable, the home agent provides notifications based upon specified events and conditions. The mobile terminal then provides an indication of the notification to the user even though a browser window is not open for displaying user messages. More specifically, the mobile IP registration process according to a mobile IP protocol is modified to add parameter extensions that allow the mobile terminal to provide this indication that it is notification capable. The home agent is notification capable as well and provides specified notifications to the mobile terminal upon the occurrence of a specified event either in a registration reply or during a data session or call.
