ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to a radio selective-calling receiver and method that gives priority to the reception of new calls and defers informing the user until the reception of the new call is finished.
DESCRIPTION OF THE RELATED ART
FIG. 1
is a process chart showing a procedure of receiving the information at a conventional radio selective-calling receiver system. Recently, various communication systems have been used for paging systems, this system is an example. The data shown in
FIG. 1
are constituted of a data structure part
20
, a cycle structure part
21
and a frame structure part
22
.
The mentioned above data structure part
20
has fifteen cycles numbered from 0 to 14 and fifteen cycles are one hour. Therefore this one cycle is four minutes. The cycle structure part
21
has 128 frames numbered 0 to 127. Therefore this one frame is 1.875 seconds.
The frame structure part
22
is constituted of a synchronizing signal and eleven blocks numbered 0 to 10. And data of one frame is divided to eight parts corresponding to the contents of the data. These eight parts are a synchronizing part
22
A, a frame information part
22
B, a synchronizing part
22
C, a block information part
22
D, an address field
22
E, a vector field
22
F, a message field
22
G and an idle block
22
H.
The synchronizing part
22
A is standard information that stipulates the frame type, that is, a modulation system and a transmission rate. The frame information part
22
B is the information that stipulates the frame number in the frame structure part
22
, the cycle number in the data structure part
20
and so forth. The synchronizing part
22
C is timing information of the frame type stipulated at the above mentioned synchronizing part
22
A. The block information part
22
D, the address field
22
E, the vector field
22
F, the message field
22
G and the idle block
22
H are frame information transmitting by the frame type stipulated at the synchronizing part
22
A.
The block information part
22
D is a block which stores the starting point of the address field
22
E, the start point of the vector field
22
F, a system variable receiving cycle value which a receiver stipulates a frame to be received and so forth. The address field
22
E is a field that stipulates an address code being a calling number of a radio selective-calling receiver.
The vector field
22
F is a field that stipulates message information regarding the mentioned above address code. The message field
22
G is a field that stores message data corresponding to the contents stipulated at the vector field
22
F. The idle block
22
H is a block not used and stores a pattern being a series of 1 and 0.
The low power consumption is required, therefore the receiver at the mentioned above system implements intermittent receiving operation. This intermittent receiving operation is implemented by the variable receiving cycle value obtained from the block information part
22
D. Only at the frame in which the own calling number exists (hereinafter referred to as own frame), the receiving section is operated. Therefore, at the time when the own calling number is received at the own frame, the message corresponding to the calling number is received in sequence and the informing operation to the receiver is implemented.
The Japanese Patent Application Laid-Open No. HEI 4-286429 discloses a radio selective-calling receiver which implements informing operation at predetermined time, even receives many messages, and can also give priority from which message a user takes out. This receiver provides a memory and a timer, the messages are stored in the memory and are outputted at the predetermined time set by a built-in timer.
The Japanese Patent Application Laid-Open No. HEI 9-116942 discloses a radio selective-calling receiver which provides a memory and a timer. This receiver has almost the same functions as mentioned above and first memorizes the information and informs the user the received information at the predetermined time set by the user.
The Japanese Patent Application Laid-open No. HEI 9-331566 discloses a radio selective-calling receiver which implements informing operation after finishing setting an added function such as registering telephone numbers. This receiver provides a photoelectric switch which detects the open/close state of a lid of the receiver and a memory. At the time of setting an added function, the lid is opened and this open state of the lid is detected by the photoelectric switch. At the case that a message is received during the setting, the message is memorized in the memory. After finishing the setting, the lid is closed and the signal detected from the photoelectric switch is outputted and the message is informed to the informing means by the control of the controller.
However, the conventional radio selective-calling receiver has restriction on its circuit physically and operationally, under the request of small sized and low power consumption. Therefore, there is a problem that the own operation of the receiver such as the informing operation of the received contents to the informing means influences the receiver itself and causes the deterioration of the receiving sensitivity.
Moreover, plural circuits operate at the receiving operation with the same time operation of informing operation of the received contents inside the receiver. And then the current consumption increases, therefore there is a problem that the burden loaded to the DC/DC converter being the power supply of the receiver is increased.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide a radio selective-calling receiver with deferring function informing the received contents and a method thereof which in particular decreases the bad influence for receiving operation.
According to a first aspect of the present invention, for achieving the above mentioned objects, a radio selective-calling receiver with deferring function informing the received contents at a paging system in which calling numbers are divided into some groups and calling contents are transmitted in some time unit, provides an informing means for informing the received calling, and a judging means for judging whether the informing operation is deferred or not, and implements said judgement by based on either that own calling number is transmitted just before the informing operation or that said own calling number is transmitted by successive frames.
According to a second aspect of the present invention, in the first aspect, said deferring operation of the received contents is that the informing operation is not implemented soon after said frame is received and is temporarily stopped, and after said next frame is received, said stopped operation is cancelled and the informing operation is implemented.
According to a third aspect of the present invention, a radio selective-calling receiver with deferring function informing the received contents, provides a data separating means for outputting the received data corresponding to the predetermined sampling clock, an address checking means for checking whether the own address number exists in said received data outputted from said data separating means or not, a received frame judging means for judging whether the next frame to be checked at said address checking means is the own frame transmitted own address or not, and a controller for controlling the operation of each means, and controls the power supply based on the judgement by said received frame judging means.
According to a fourth aspect of the present invention, in the third aspect, a radio selective-calling receiver with deferring function informing the received contents, provides a receiving means which amplifies and modulates the received signals from the designated communication base station and outputs the demodulated signals.
According to a fifth aspect of the present invention, in the first aspect, said informing means informs the designated information to a user, based on said received frame judg
