Abstract

There is provided a communication apparatus including a plurality of radio transmitter sections, which is capable of suppressing unnecessary radiowaves from being generated due to mutual modulation distortion without increasing the size and weight of the whole apparatus. When the communication apparatus receives a signal from a radio base station and it coincides with the ID of a station when one transmitter section is operative, it rejects a process for the incoming call request. Therefore, no transmission is made simultaneously by the different radio transmitter sections, and the quality of the radiowaves transmitted may be kept high.

Claims

1. A communication apparatus comprising:

a plurality of radio transmitter sections;

transmission control means for, when one of the plurality of radio transmitter sections is engaged in transmission, rejecting a transmission request which is made to another radio transmitter section of the plurality of radio transmitters which is not engaged in transmission; and

first and second antennas, wherein a duplexer is connected to the second antenna but not the first antenna so that first and second of the radio transmitter sections can share the second antenna, but not the first antenna which is only used by the first radio transmitter section.

2. A communication apparatus comprising:

a plurality of radio transmitter sections; and

transmission control means for, when specific one among the plurality of radio transmitter sections is engaged in transmission, holding a transmission request which is made to another radio transmitter section thereamong which is not engaged in transmission, and validating the held transmission request when the transmission of the specific radio transmitter section ends so that the held transmission request is automatically processed to originate a corresponding transmission from the communication apparatus when the transmission of the specific radio transmitter section ends so that a user does not have to again have to manipulate an input section of the communication apparatus to actuate the held transmission request.

3. A communication apparatus comprising:

a plurality of radio transmitter sections;

a radio receiving section; and

transmission control means for, when specific one among the plurality of radio transmitter sections is engaged in transmission, judging a transmission request which is made to another radio transmitter section thereamong which is not engaged in transmission, whether or not the transmission request is of a signal which is produced based on information repeatedly received by the radio receiving section;

rejecting the transmission request when the transmission request is of a signal which is produced based on the received information and holding the transmission request when being not of the signal; and

validating the held transmission request when the transmission of the specific radio transmitter section ends so that the held transmission request is automatically processed to originate a corresponding transmission from the communication apparatus when the transmission of the specific radio transmitter section ends so that a user does not have to again have to manipulate an input section of the communication apparatus to actuate the held transmission request.

4. The communication apparatus of claim 3, further comprising:

storage means for storing information received by the radio receiving section and/or information related to the received information when the transmission control means rejects the transmission request.

5. A communication system comprising the communication apparatus of claim 4;

and further comprising;

an exchange for transmitting a transmission request to the communication apparatus,

the communication system using a communication sequence requiring a response from the communication apparatus to the transmission request from the exchange, wherein a message from the exchange of the communication sequence before the response from the communication apparatus contains information regarding a pager.

6. The communication apparatus of claim 3, further comprising:

announcing means for announcing information received by the radio receiving section and/or information related to the received information when the transmission control means rejects the transmission request.

7. A computer readable medium on which a computer program for computer control of transmission operation of a communication apparatus comprising a plurality of radio transmitter sections is stored, the computer program comprising:

judging whether or not specific one among the plurality of radio transmitter sections is engaged in transmission;

in the case where the specific transmitter section is engaged in transmission, holding a transmission request which is made to another radio transmitter section thereamong; and

validating the held transmission request when the transmission of the specific radio transmitter section ends so that the held transmission request is automatically processed to originate a corresponding transmission from the communication apparatus when the transmission of the specific radio transmitter section ends so that a user does not have to again have to manipulate an input section of the communication apparatus to actuate the held transmission request.

8. A computer readable medium on which a computer program for computer control of transmission operation of a communication apparatus comprising a plurality of radio transmitter sections is stored, the computer program comprising:

judging whether or not specific one among the plurality of radio transmitter sections is engaged in transmission;

in the case where the specific transmitter section is engaged in transmission, judging whether or not a transmission request is of a signal which is produced based on information repeatedly received by the radio receiving section;

in the case where the transmission request is of a signal which is generated based on the received information, rejecting the transmission request, and holding the transmission request when being not of the signal which is generated based on the received information; and

validating the held transmission request when the transmission of the specific radio transmitter section ends so that the held transmission request is automatically processed to originate a corresponding transmission from the communication apparatus when the transmission of the specific radio transmitter section ends so that a user does not have to again have to manipulate an input section of the communication apparatus to actuate the held transmission request.

9. The computer program of claim 8, wherein the communication apparatus further comprises storage means, and

the control program causes the storage means to store information received by the radio receiving section and/or information related to the received information in the storage means when the transmission request is rejected.
