Abstract: The invention includes a method and apparatus for activating a base station. A method includes transitioning the base station to a first state in which at least one base station activation activity is performed and RF transmissions are disabled, and transitioning the base station from the first state to a second state in which RF transmissions are enabled. The at least one base station activation activity may include at least one of warming at least one power amplifier, setting at least one base station configuration parameter, establishing GPS synchronization, and other base station activation activities. The base station may transition from the first state to the second state in response to a trigger.

Abstract: A temporary multimedia ELAN is formed on top of one or more existing ELANs between those end-stations (121-1, 121-2, 111-1) participating in a multimedia session, such as a video conference, at the time of initiating the session. At the end of the session the temporary ELAN is torn down. When the temporary ELAN is created an available LAN Emulation Server (LES) (241) and an available Broadcast and Unknown Server (BUS) (243) are allocated to serve those end-stations participating in the multimedia session. The BUS also serves as a multicast server to multicast a multimedia stream from one end-station to each other end-station on the temporary ELAN. The initiator of a session accesses a Multimedia Session Manager (401), which oversees and manages the session and coordinates the necessary resources.

Abstract: An adjunct message system, coupled to a global telecommunications network, provides a roaming subscriber with roaming access to messages left at the subscriber's home mailbox by transferring such messages to a temporary roaming mailbox at a roaming node when the subscriber first calls to retrieve his/her messages. In addition, messages left at any node in the system will be transferred to the subscriber's home node. In both cases, international voice transport costs will be saved.
