Method for sending messages over secure mobile communication links

摘要

Messages are sent over secure communication links in networks with a mobile terminal and another terminal. A secure communication link is established between an initial network address of the mobile terminal and the address of the other terminal. When the mobile terminal moves from the initial network address to a new network address, a request message is sent from the mobile terminal to the other terminal to change the secure connection to be used between the new address and the other terminal. The other terminal responds with a reply message with a description about the overcoming methods supported by the other terminal.
