## Abstract

A radio selective-calling receiver that defers indication of receipt of a call for the receiver until after a further frame when the further frame is also for the receiver. A data separating section takes in demodulated signals by sampling. When the receiver's calling number exists in the received data, a controller waits until the next frame that is also an “own” frame, to output display signals or sound signals. Therefore, at the time when the own address is being received, the informing operation can be prevented and the receiving operation can be implemented in a more stable receiving state. As a result, the deterioration of the receiving sensitivity is prevented and the effect that the error of the receiving data is decreased can be obtained.

## Claims

### Claim 1

A radio selective-calling receiver to which a signal is directed that has a series of frames that each contain call information, the receiver receiving frames selected from the series of frames that are directed to the receiver and that are named own frames, the receiver comprising:
informing means for indicating receipt of call information directed to the receiver in one of the own frames; and
deferring means for deferring operation of said informing means until after receipt of a frame immediately following the own frame with the call information when the immediately following frame is also one of the own frames.

### Claim 2 (depends on 1)

The receiver of claim 1, wherein said deferring means defers operation of said informing means until immediately after receipt of the following frame.

### Claim 3 (depends on 1)

The receiver of claim 1, wherein said deferring means comprises address checking means for checking whether the receiver's address is in the received call information and received frame judging means for determining whether the immediately following frame is one of the own frames.

### Claim 4

A radio selective-calling receiver to which a signal is directed that has a series of frames that each contain call information, the receiver receiving frames selected from the series of frames that are directed to the receiver and that are named own frames, the receiver comprising:
informing means for indicating receipt of call information directed to the receiver in one of the own frames; and
deferring means for deferring operation of said informing means until after receipt of a second one of the own frames that is separated from the own frame with the call information by one of the frames that is not one of the own frames.

### Claim 5 (depends on 4)

The receiver of claim 4, wherein said deferring means defers operation of said informing means until immediately after receipt of the second own frame.

### Claim 6 (depends on 4)

The receiver of claim 4, wherein said deferring means comprises address checking means for checking whether the receiver's address is in the received call information and received frame judging means for determining whether the immediately following frame is one of the own frames.

### Claim 7

A method of operating a radio selective-calling receiver to which a signal is directed that has a series of frames that each contain call information, the receiver receiving frames selected from the series of frames that are directed to the receiver and that are named own frames, the method comprising the steps of:
indicating receipt of call information directed to the receiver in one of the own frames; and
deferring the indicating step until after receipt of a frame immediately following the own frame with the call information when the immediately following frame is also one of the own frames.

### Claim 8

A method of operating a radio selective-calling receiver to which a signal is directed that has a series of frames that each contain call information, the receiver receiving frames selected from the series of frames that are directed to the receiver and that are named own frames, the method comprising the steps of:
indicating receipt of call information directed to the receiver in one of the own frames; and
deferring the indication step until after receipt of a second one of the own frames that is separated from the own frame with the call information by one of the frames that is not one of the own frames.
