Abstract
A destination to which a line connection is not established is memorized in the process of simultaneous multicasting to a plurality of destinations. When another multicast communication starts, if the memorized destination is included in destinations, a call is primarily performed to a destination in the next order by skipping the memorized destination.
Claims12
A method for simultaneous multicasting to a plurality of destinations, said method comprising the steps of:
- memorizing one or more destinations to which a line connection is not established in a multicast communication for simultaneous multicasting to a plurality of destinations;
- deciding whether or not a destination to which a call is performed in a current progress multicast communication is the same destination to which a line connection is not established in the previous multicast communication;
- and
- calling to a destination in the next order by skipping the same destination as the destination to which a line connection is not established.
A method for simultaneous multicasting to a plurality of destinations, said method comprising the steps of:
- detecting a communication error occurred in the process of simultaneous multicasting to a plurality of destinations;
- identifying the error type of the detected communication error;
- and
- calling again to the same destination in the case where the error type is identified as recommunicatable one, and forbidding to call again to the same destination in the case where the error type is identified as inrecommunicatable one.
A communication apparatus for multicast communicating comprising:
- means for simultaneous multicasting a plurality of destinations;
- means for setting a redial interval for a destination to which a line connection is not established;
- memory means for memorizing an error information concerning a destination to which a line connection is not established;
- means for deleting the error information of a destination to which a line connection is completed in said memory means;
- means for starting a plurality of multicast communications sequentially during a redial interval;
- and
- control means for control a call order to skip a destination which error information is registered in said memory means.
A communication apparatus for multicast communicating comprising:
- means for simultaneous multicasting a plurality of destinations;
- means for setting a redial interval for a destination to which a line connection is not established;
- means for starting a plurality of multicast communications sequentially during a redial interval;
- and
- memory means for memorizing the error type of communication error occurred;
- means for controlling not to call a destination which error type is memorized as an recommunicatable one in said memory means.
A communication apparatus for multicast communicating comprising:
- means for simultaneous multicasting the same paper document data to a plurality of destinations;
- means for setting a redial interval for a destination to which a connection is not established and
- control means for controlling a call order, when a plurality of simultaneous multicasts are performed, in the case where a destination set a redial interval in a simultaneous multicast is included in destinations in another simultaneous multicast, to skip said destination in said another simultaneous multicast.
A communication apparatus for multicast communicating comprising:
- means for simultaneous multicasting the same paper document data to a plurality of destinations;
- means for memorizing an error information concerning a destination to which a connection is not established for each paper document data;
- and
- control means, when a plurality of simultaneous multicasts are performed, for not calling to a destination which error type is memorized as an inrecommunicatable one in a simultaneous multicast, and changing to another simultaneous multicast processing.
