It the object of the present invention is to provide a radio selective-calling receiver, when can provide full-time correct day under the situation that does not influence receiving feature.
According to the present invention, radio selective-calling receiver comprises time holding circuit, radio-circuit and first controller.Radio-circuit receives wireless signal off and on from the wireless base station, this wireless signal comprises temporal information.A plurality of operations of first controller control radio selective-calling receiver, this operation comprises the time adjustment of time holding circuit.Radio selective-calling receiver also comprises second controller, its following mode is controlled the start-up time of first controller: when radio-circuit does not receive operation, first controller starts with the basic enterprising line time in temporal information to be proofreaied and correct, when radio-circuit receives operation, first controller waits until that radio-circuit is finished and receives operation, and starts subsequently with the basic enterprising line time in temporal information and stand-by period and proofread and correct.
Comprise the time holding circuit at radio selective-calling receiver, radio-circuit and data processor are carried out under the situation of the operation that comprises time adjustment according to master clock signal, when radio-circuit is not carried out the reception operation, master clock signal is added on the data processor, proofread and correct with basic enterprising line time in temporal information, when radio-circuit is carried out the reception operation, master clock signal is not added to data processor till the reception operation is finished, after the reception operation was finished, master clock signal was added to data processor and proofreaies and correct with the basic enterprising line time in temporal information and stand-by period during not being added to data processor at master clock signal.
Fig. 1 is a block diagram, and radio selective-calling receiver according to an embodiment of the invention is shown;
Fig. 2 is a flow chart, and the control operation of control section among the embodiment is shown;
Fig. 3 is a sequential chart, and the operation of Fig. 1 embodiment is shown.
See Fig. 1, wireless system 101 is through the signal of built-in antenna reception from selective calling system base station (not shown).The wireless base station comprises temporal information when the day before yesterday with predetermined period emission as described later.Wireless system 101 comprises a demodulator, and it is demodulated to baseband signal with the wireless signal that is received.This baseband signal sends on the processor controls (or decoded portion) 102 from wireless system 101 as selective call signal.
In addition, processor controls 102 usefulness RAM105 store the temporal information of receiving from the base station, if necessary, also store the stand-by period that obtains from power-saving control device 104.Temporal information is delivered to CPU106 as described later, and if necessary, the stand-by period is also delivered to CPU106 together.CPU106 has the master clock handoff functionality, and it is controlled by processor controls 102.The not shown clock generator of this figure.Specifically, master clock was added on the CPU106 in the power saving phase, had spent the power saving phase and had not then added.In other words, CPU106 was by master clock work when wireless system 101 quit work, and on the contrary, CPU106 quits work, just work of wireless system 101.
When the selective call number in the received data was consistent with id number, after power-save operation began, there was it among RAM107 in the reception information that processor controls 102 comprises in CPU106 output received data subsequently.At this moment, CPU106 is according to user instruction control display 108 and device for informing 109, and like this, information is presented on the display 108 and by sound, vibration or light and informs that with device for informing 109 user uses incoming call, among this figure, the keyboard that user input instruction is used is not shown.
In addition, when CPU106 links independently such as day on the time holding circuit 110 of clock or clock/calendar, and has time correction function and the Ri Shi Presentation Function shows time and date with the indication according to the user on display 108.Carried out the correction of time from temporal information and the stand-by period of controlling processor 102 since the CPU106.
Store control program among the ROM111, this program is carried out above-mentioned control operation by processor controls 102 and CPU106.
See Fig. 2, wireless system 101 is carried out intermittent reception operation under the control of power-saving control device 104 (step S201).When receiving wireless signal (step 202 is for being), processor controls 102 checks whether the data that receive comprise temporal information (step S203).When not comprising temporal information (step S203 for not), processor controls 102 further check the selective call number that comprises in the data that received whether be stored in ID ROM103 in id number consistent (step S204).Consistent if (step S204 is for being), after power saving starts, master clock is added on the CPU106, CPU106 has incoming call (S205) by sound, vibration or light indication device for informing 109, shows the message (step S206) that receives with display 108 on screen.
When the data that received comprise temporal information (step S203 is for being), processor controls 102 checks that further whether power saving starts (step S301).If after power saving started, master clock then was added to CPU106 (step S302).Subsequently, proofread and correct (step S303) by CPU106 by the temporal information time of implementation that is received.
If power saving is closed, processor controls 102 deposits the temporal information that is received among the RAM105 (step S304), and asks the stand-by period from power-saving control device 104.Stand-by period is exactly to start to power saving to be last storage life.When power-saving control device 104 is received the stand-by period (step S305), processor controls 102 is waited for up to stand-by period intact excessively (step S306).After the stand-by period has crossed (step S306 is for being), master clock just is added to CPU106 and goes up (step S307), and CPU106 calculates the current time (step S308) by being added to the stand-by period on the temporal information that is received.So CPU106 carries out time adjustment (step S309) by calculating the current time.
Under the situation of synchro system, the description of step S304-S309 will be more concrete.
See Fig. 3, the wireless base station emission of system has transmitting of following form.A cycle of H hour comprises the M frame, and every frame comprises N piece, and wherein temporal information is to launch in H hour cycle, shown in figure (a).Temporal information T when representing day herein, sends in piece X.When wireless system 102 work, i.e. during power saving closing control processor 102 time of receipt (T of R) information T, processor controls 102 sends to RAM105 with the temporal information T that is received, and to the 104 request stand-by period of power-saving control device.In this figure, the stand-by period is counted Y+1-X representative by piece, shown in figure (b) from piece X to piece Y+1.
After the stand-by period, (Y+1-X) crossed, processor controls 102 was exported main time control signal to CPU106, thereby master clock is added to CPU106.Meanwhile, processor controls 102 is to CPU106 output time information T and stand-by period (Y+1-X).With t and Y+1-X, CPU106 calculates current time t+ (Y+1-X) H/MN, shields when going up the day that shows thereby proofread and correct shown in Fig. 3 (d).
In this way, the master clock that is added on the CPU106 waits until that subsequently, CPU uses the current time and the stand-by period that calculate to carry out time adjustment till the power saving startup from the temporal information that is received.Like this, need not influence wireless system 101 and just can on screen, always show orthochronous.
Do not adopting under the situation of the present invention, master clock is added to CPU106 and proofreaies and correct with the time of implementation shown in Fig. 3 (C) after temporal information T has just received.In the case, master clock will influence the receiving feature of wireless system 101 conversely as prior art.
