<P>PROBLEM TO BE SOLVED: To provide a communication system that can perform selective call operation simply and easily. <P>SOLUTION: A center station refers to a registration table 240 stored in advance and acquires individual numbers 1 to 4 corresponding to a call target group number 1, when acquiring the call target group number 1 and the individual number 2 which is to be excluded from the call for the group number 1 by operation of an operator. The center station deletes the individual number 2 designated as an exclusion target by the operator from the acquired individual numbers 1 to 4, generates a report start instruction telegraphic message in which the individual numbers 1, 3, and 4 are stored in a slave station identification number field, and transmits the message. Thereby, the operator can perform selective call operation for a desired slave station by selecting the call target group number and the individual number of the exclusion target, even when the individual number the operator desires to exclude is included in the call target group number. <P>COPYRIGHT: (C)2012,JPO&INPIT |
