Abstract
Mobile terminal handoff control is provided for point to multipoint (PMP) connections in Mobile ATM networks. Special issues for the handoff control in all three types of PMP connections are taken care of, including cross over switch discovery and handoff path re-routing. A protocol for a PMP connections signaling mechanism is presented, which works with all three types of PMP connections and has a lossless control function. The PMP connection tree topology is protected.
