System having virtual session manager used sessionless-oriented protocol to communicate with user device via wireless channel and session-oriented protocol to communicate with host server

摘要

A communication system includes a virtual session manager (225) for establishing and maintaining a sessionless communication path with a user device (201) on the one hand and a session-oriented communication path with a host system (231). The session-oriented connection with the host system permits normal access to, e.g., LAN-based applications, while the virtual session between the virtual session manager and user permits this access to be carried out remotely without the expense of a dedicated/circuit-switched or other session-oriented connection.
