Fig. 3 describes the flow chart that is shown in the radio pager receiver ruuning situation among Fig. 2.
With reference to Fig. 1,, the ruuning situation of traditional paging receiver is described at first for understanding the present invention better.Traditional paging receiver receives a plurality of call signals of pointing to this receiver selectively.Each call signal comprises a call number signal and the message signale after this call number signal, sends (not shown) as radio signal from dispatching station.This message signale is represented information.This call number signal representative is assigned to the call number of the paging receiver that receives this message.As known in the art, traditional paging receiver comprises a memory that is used to store a plurality of particular messages.
In Fig. 1, the beginning step enters first step SA1, in this step whether this paging receiver is received to be assigned to this call number of leading paging receiver and to judge.When receiving this, this paging receiver exhales when collecting the digits yard, behind first step SA1, enter the second step SA2, the reception operation that this paging receiver is scheduled in this step, more particularly, paging receiver is decoded as information with message signale, so that the combination of this information and additional information is imported message stores in message buffer well-known in the art as one.
Enter the 3rd step SA3, in this step, import the compare operation between the particular message of a message and a selection.In the 4th step SA4, import the judgement whether message and the particular message of selection are consistent.When input message is consistent with the particular message of selection, enter the 5th step SA5, in this step, should import message and from message buffer, delete, and not be stored in the message memory.Enter end step after the 5th step SA5, finish in this step operation.
When the particular message of input message and selection is inconsistent, enter the 6th step SA6 after the 4th step SA4, judge whether whole particular messages are all compared operation in this step.When having at least a particular message not compare when operation, be back to the 3rd step SA3 from the 6th step SA6, carry out compare operation between this input message and that particular message in this step.Repeated for the 3rd step to the 6th step, i.e. SA3 to SA6.
When whole particular messages all being compared when operation, enter the 7th step SA7 from the 6th step SA6, should import that message is read and be stored in the message memory from message buffer in this step as a particular message.In the 8th step SA8, a light-emitting diode and a loud speaker are driven, and notify the reception condition of this input message with the holder to this receiver.Enter into end step behind the 8th step SA8, finish in this step operation.
Because the compare operation of whole particular messages is carried out successively, traditional paging receiver has such shortcoming, and whether need judge for a long time needs this input message stores in message memory.Under the situation that quantity is very big or input message number of words is many of particular message, this shortcoming is just more serious.In order to eliminate this shortcoming, paging receiver should comprise the computer processor of a function admirable.Yet such microprocessor can make paging receiver become expensive.
As is generally known in the art, after power supply was disconnected from this receiver, traditional paging receiver had the storage reserve function that keeps particular message in message memory.Supposition input message is consistent with the particular message in a Geju City in this respect, like this, traditional paging receiver just has another shortcoming, if this old particular message was stored in the past at several days in the message memory, this input message just can not deposit this message memory in so.
Translate into Fig. 2, will the paging receiver of most preferred embodiment of the present invention be described.This paging receiver comprises an antenna that is used to receive radio signals 11, and radio signal is added on the wireless device part 12 after being picked up by antenna 11.Wireless device part 12 is with this radio signal conversion or be demodulated into baseband signal or restituted signal.This restituted signal is added on the decoder 13.As known, wireless device part 12 is according to working intermittently from the energy-conservation signal of battery of decoder 13 Calais.
