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.

Mobile IP notification

The present invention supports a secure transmissions protocol for information packet transmission between a Mobile Node and a Foreign Agent. The information packets are encrypted and decrypted using an integrated software client that combines mobile IP communication support and encrypting and decrypting protocols.

Security transmission protocol for a mobility IP network

A method and apparatus in accordance with the present invention includes a home agent and a mobile terminal that communicate to facilitate the home agent becoming aware of a device type and access technology being used to gain access to a network by way of the home agent so that the home agent may provide appropriate billing and network control. 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 information. The two specific parameters that are added include one that defines the access technology and another that defines the device type in the described embodiments of the present invention. Specifically, the extension that defines the access technology includes a mobile IP client that has operator definable configurations that relate to the access technology. The mobile IP client specifies whether a wireless local area network or wireless cellular network is being used and, in one embodiment of the invention, which type of wireless local area network or cellular network is being used.
