Abstract
A multilevel session management protocol is provided to support communications mobility in a telecommunications system. A session is separated into two independent layers—a terminal session layer and an application session layer. A session management agent is implemented as a module operating locally in a wireless terminal. A second session management agent is implemented as a module operating remotely in the Internet. Any session management agent module can communicate with another session management agent module by use of the session management protocol. The two session management agent modules use a multiplexed TCP connection for conveying TCP data traffic therebetween. As such, the session management protocol can be used with any application that uses an Internet TCP as a transport protocol.
