Abstract: In an agent system having a plurality of agents each of which executes predetermined processing while moving through a plurality of nodes connected to an information network, the plurality of nodes respectively have a plurality of agent platforms which receive and execute the agents, one of the agent platform and the node has synchronization means, and when the plurality of agents which are running on the same node should synchronously execute operation, the plurality of agents on the same node execute processing synchronously by sending a synchronization request message to the synchronization means.

Abstract: Multiplex transmission apparatus 10 on the transmitting side multiplexes received signals from non-voice signal input output apparatus 14 and voice signal input output apparatus 16, and also transmits the multiplexed signal from communications network 30 by digital portable telephone 12 on the transmitting side. The digital portable telephone transmits a signal per 20 msec, so that multiplex transmission apparatus 10 alternately transmits the voice signal and the non-voice signal at an interval of 20 msec, for example. Multiplex transmission apparatus 20 sorts out the voice signal and the non-voice signal from the supplied signal by checking the error detecting code of the supplied signal. Multiplex transmission apparatus 20 can judge the type of the signal according to the type of the error detecting code, because a different error detecting code is added to each signal.

Abstract: When the telephone number of digital portable telephone A is notified to reception notifying apparatus 3 (S101), the telephone number is stored (S102), and is forwarded to digital portable telephone B (S103). Next, when digital portable telephone B transmits a CALL SETUP signal and a sending number to digital portable telephone A (S104, S105), digital portable telephone A transmits a CALL PROC signal and an ALERT signal to digital portable telephone B (S106-S109). After that, information indicating that the busy line display is ON is forwarded to reception notifying apparatus 3 (S110), and the telephone number is deleted (S111). Furthermore, reception notifying apparatus 3 transmits a voice guidance to digital portable telephone A (S114).

Abstract: This invention provides a mobile communication system in which a call-incoming side can switch a communication line to an appropriate one which corresponds to a communication type requested by a transmitter's terminal. One example of its construction is as follows.A mobile station has a plurality of terminal units corresponding to plural types of communication and a call number is preliminarily assigned to each of them. A terminal unit in a telephone network uses a call number corresponding to a desired communication type when a datum is transmitted to the mobile station. The mobile station informs this call number to all of the terminal units which are connected to the mobile station. The respective terminal units inform the communication type to the mobile station only when the communication type corresponding to the call number can be handled. The mobile station informs this communication type contained in a reception call receiving signal to a mobile communication exchange.
