Abstract: An integrated switch for simultaneously processing IP data and voice signals and a switching method thereof are provided to transmit data packets by using the silent period while a call is being performed through the same channel. A plurality of line cards(110-1-110-n) convert a plurality of subscribers' voice signals into digital signals, and add an identifier which shows the silent period of the voice signals to plural subscriber IP data. A switch matrix(120) switches the converted voice signals and the IP data including the silent identifier at the same time. A plurality of input-output trunks(130-1-130-m) remove the silent identifier from the IP data, and then transmit the converted voice signals to an external voice phone trunk.

Abstract: A system and a method for processing blinking data of an RTLS tag are provided to loosen overload of a location determination engine by periodically collecting information of the locatable tags through filtration before the blinking data is transferred to the location determination engine and transferring only the valid blinking data to the location determination engine. A tag hash table(32) groups the inputted blinking data of a plurality of RTLS tags by classifying into each tag having the same ID and determines locatability of each grouped tag. A tag stream output queue(33) receives the blinking data of only the tags determined as the locatable tag from the tag hash table and transfers the received blinking data to the location determination engine(34). If an information storing part of the tag ID is empty by a blinking data grouping result of the RTLS tags, the tag hash table determines that the tag corresponding to the tag ID is always locatable.

Abstract: A path setting method of a complex switch which provides real time mobility of an IP address and a telephone number are provided to enable a telephone terminal and an IP terminal to use an existing intrinsic address system when the IP terminal and the telephone terminal moves to a network area having a different number system. A mute detection unit detects a mute period(S402). An IP(internet Protocol) terminal detects a CoA(Care of Address) that a complex switch sends during the mute period(S404). The IP terminal transmits a registration request message to the complex switch(S405). It is determined whether information that the complex switch sends is a registration response message(S406). When the information that the complex switch sends is not the registration response message, an operation state of a general IP terminal is maintained(S408).
