ABSTRACT:
The present invention relates to a wireless communication technology field. A method for determining a mobile IP key of a mobile terminal is provided, which includes: receiving a mobile IP registration request message of a mobile terminal, in which the mobile IP registration request message includes a key material field; and reporting material information for determining a key according to the key material field. A method for determining a mobile IP key of a mobile terminal, a mobile IP agent device, a system for obtaining a mobile IP type, and a mobile terminal are also provided. With the technical solutions provided in the present invention, the mobile IP keys and/or the mobile IP type of the mobile terminal can be correctly determined, thus achieving a fast and correct access of the mobile terminal.
