Abstract:
Flow of digitized coded speech packets through virtual circuits in a multi-node communication system (300) is controlled by an adaptive loading capacity device (102) in the nodes (314, 316, 318). The adaptive loading capacity device (102) determines an adjusted throughput data rate ATDR (602, 604) for a node (314, 316, 318) that is substantially equivalent to a predetermined upper limit of the system's capacity. When a requested data rate value RDR included in a frame (200) is greater than the ATDR, the device automatically adjusts the RDR downward to substantially equal the ATDR (702, 704) and incorporates the adjusted RDR into frames (200) transmitted to coupled nodes (314, 316, 318) and stations (302, 308).

Abstract:
A multi-site communication system (100) includes a plurality of communication units (106, 107) roaming among communication sites (108-111). The communication sites (108-111) are controlled by a central controller (100), via repeaters (102-105), and are thereby capable of establishing communication among sites. A method for minimizing message interruptions during a hand-off, of a first communication unit between two sites, includes the step of receiving (200) a message (300) from a second communication unit. During the message (300), which may be delivered at varying information rates, the first communication unit determines (202) the signal quality. If the signal quality of the message is unfavorable, the receiving communication unit determines (204) when the varying information rate of the message is favorable for a hand-off. Lastly, when the varying information rate is favorable for a hand-off, the first communication unit requests (205) the hand-off.
