In the present invention, when there is incoming voice call notification from the network in an active state (i.e. in a period in which the packet data is actually transmitted and received and in a period passing until the time when clocking interval time T is finished) while a line for packet transmission is held, incoming-call-in-packet-transmission controlling means makes a response of rejecting the incoming voice call. When there is incoming voice call notification in a standby state (i.e. in a period other than the periods of the active state), the incoming-call-in-packet-transmission controlling means makes a response of receiving the incoming voice call.

Mobile radio apparatus and control circuit thereof

A control unit transmits address area designation information designating an arbitrary bit position in ID data. At least a response unit transmits a response signal with an error detection code attached to predetermined information in the unique information held in itself by means of a time slot determined by the address area designation information and the ID data of the particular response unit. The control unit checks for the presence or absence of an error of the information in each time that has arrived, fetches only the response signal free of error, and transmits the error presence-absence information indicating the inspection result. Further, in the case where there exists a time slot having an error, the control unit transmits new address area designation information. In the case where an error exists in the time sot used previously by the response unit, the response unit retransmits the response signal in the time slot determined from the new address area designation information and the ID data of the response unit.
