摘要： Mobility in a wireless ATM network is accomplished by use of hand-off control protocols. A mobile terminal signals a first base station that a hand-off is to occur. In a first preferred embodiment the first base station signals a second base station requesting a hand-off. After the second base station signals the first base station that a datapath link is available from a hand-off switch to the second base station, the hand-off switch causes the datapath to change from the first base station to the second base station and the first base station signals the mobile terminal to commence communication with the second base station. In a second preferred embodiment, the mobile terminal signals a first base station that a hand-off is to occur. The first base station signals a second base station requesting a hand-off. At the same time a datapath link is established between the first and second base stations. When the second base station signals the first base station that the datapath link is available, the first base station signals the mobile terminal to change to the second base station and data is sent from the first base station to the second base station via the available established datapath link.

摘要： The present invention pertains to message sets for use in a flexible programmable multiplexer for accessing an Asynchronous Transfer Mode (ATM) network. The access multiplexer uses a functional separation of line related functions and protocol related functions. Line interface cards perform line related functions. A message set for use in such a multiplexing system that uses a functional separation of line and protocol related functions is provided. The message set includes a general message, a hello message, a configuration message, a line stabilized message, an identify remote message, an identify remote acknowledgement message, a reset remote message, a report statistics message, a report statistics acknowledgement message, a loopback test message and a dynamic rate adaptation message. A flexible programmable multiplexer that uses the message set is also provided.

摘要： A technique for reducing ATM call blocking is provided that splits wideband connections into multiple low-bandwidth sub-connections and routing them independently through the network. Fragmented network bandwidth is used for supporting calls which are otherwise blocked by conventional routing. A detailed cell-level design for the split scheduling algorithms is provided. A system for implementing splitting without requiring any protocol changes within the network is provided. Such a system modifies the control plane protocols only within the end-stations.
