SYSTEM AND METHOD FOR TRANSPORTING CALL IN TELECOMMUNICATION NETWORK

摘要

PURPOSE: A low-power processor is provided for a high speed and low power consumption by realizing substrate bias control of a processor chip which is applied to various operation modes of the processor. CONSTITUTION: A first communication device(106) transmits a call having call signals and user communications. A signaling processor(112) receives the call signals from the first communication device and selects a connection to a second communication device(108). An inter-working unit(114) receives the user communications from the first communication device and converts the user communications from a time division multiplex format to the asynchronous transfer mode cells that identify a selected connection to the second communication device. The inter-working unit detects a call trigger in the user communications. The inter-working unit transmits call trigger data to the signaling processor. The signaling processor processes the call trigger data and, upon validating the call trigger, instructs the inter-working unit to transport the user communications to asynchronous transfer mode cells that identify the selected connection to the third communication device(110) and transports the user communications to the third communication device.
