A plurality of details have been provided in the following description, to help the more complete the present invention that understands.But need not these details, one of ordinary skill in the art also can finish the present invention.In other examples, known 26S Proteasome Structure and Function is not described in order to avoid the present invention is complicated.

With reference to figure 2, if the user sends a beep-page message by the

subscriber phone

300 or 400 requests of faxing, beep-page message just is sent to call terminal 32 by switching system or public switch telephone network (PSTN) 200.Call terminal 32 call signaling protocol beep-page messages.If calling-signaling-protocol message is a POCSAG signal, call terminal 32 is determined an accurate time slot and the POCSGA signal is sent to corresponding paging receiver by using from the GPS information of GPS500 reception, for example pass through a plurality of base station apparatus 22 at time slot 52 ... 24.GPS is the automatic station-keeping system that adopts satellite.Just, GPS receives the information of relevant time and position and uses the triangle principle and find out current three-dimensional position and time from 24 satellites.

Fig. 3 is the detailed diagram of call terminal 32 shown in Figure 2.Controller 30 controls are through the reception and the transmission of the beep-page message of PSTN.A database, information that memory 30 is used to store relevant paging receiver just, it and the call signaling system co-operate that is connected with controller 30.The address of paging receiver, type of message (voice, numeral or letter) and time slot group information etc. are stored in the memory 31.Time slot group information is specified in advance by system and is determined according to the address of paging receiver.Again with reference to Figure 1A, address code word comprises an address/data sign bit, one 8 bit addresses part (bit 2-19), one 2 bit addresses multiplier part (bit 20 and 21), one 10 bit check part (bit 22-31), a piece is checked bit (bit 32).Determine time slot group information with the information of address part.Just, can determine time slot group information according to the odd even of the value of information of address part.In addition also can according to the value of information of address part with 2 or the bigger value remainder that removes gained judge.Page queue 34 is stored the beep-page message of the stand-by state that receives through PSTN provisionally.In this page queue 34, divide a zone with storage and the corresponding time slot of time slot group information.Data encoder 33 is converted to the POCSAG signal with the beep-page message of page queue 34, and this signal can pass through base station unit 22 ... 24 are sent to paging receiver.The time that timing device 35 control operation call terminals 32 are required.

Fig. 4 is the block diagram of paging receiver according to a preferred embodiment of the present invention.RF device 41 paging receiving information are also carried out such as frequency inverted, separate to be in harmonious proportion and put in order the such function of ripple.The output of RF device 41 is the paging informations through digital translation.The prefix data that sign indicating number type detector 52 detects from RF device 41.An address and the message that address/message detector 54 detects from the output of RF device 41.Battery is saved controller 42 opens or closes the RF device by the control of controller 44 power supply.Decoder 56 is by a kind of operator scheme of the control setting paging receiver of controller 44.At idle pulley, decoder 56 controls are powered to RF device 41 so that a sign indicating number type detector 52 can detect prefix data.Under group mode, decoder 56 controls are powered so that the address message detector can detect synchronization character data and frame data to RF device 41.Decoder 56 is decoded as detected frame data the form of initial data in addition.The operating time of second clock generator 58 control decoders 56.Controller 44 is handled the data through decoding and is controlled an alarm function from the data that decoder 56 receives through decoding.Controller 44 also produces a decoder inhibit signal DH, so that battery is saved the power supply that controller 42 turn-offs RF device 41.Alarm device 43 can be a vibrator or buzzer.Alarm device 43 produces an alarm signal, such as voice signal or vibration signal, is received by the alarm control signal that slave controller 44 produces to notify a calling.Display unit 45 passes through to show the message of the control signal display of calling that is produced by controller 44 and the state information of paging receiver.Memory 46 memory allocation are given the unique address information of paging receiver, frame information and the message that receives.First clock generator 47 will be operated the required clock of paging receiver and offer controller 44.Controller 44 sensings are by the state of operation timer 60 with the time slot of constant time span repetition.Key in device 48, it is a user interface facilities, a plurality of affirmation beep-page messages is arranged or the required key of various patterns is set.

Fig. 5 is a flow chart, and the operating process of call terminal according to a preferred embodiment of the invention is described.

The supposition paging the request when crack produces in office is sent immediately or is sent out at next time slot at this time slot in Fig. 5.The flow process of Fig. 5 is divided into an operation at n time slot, the operation of a current time slots, the operation of a n+1 time slot and the operation of next time slot (wherein n is an even number).

In step 5A, call terminal 32 shown in Figure 2 checks whether receive beep-page message by PST200.By subscriber phone, input such as facsimile machine also sends to call terminal 32 by PSTN200 to this message by the user.If beep-page message is received, the beep-page message of being asked is classified according to the information and the timing device 35 of memory 31.In more detail, calculate the CAP sign indicating number that is included in the called paging receiver in the beep-page message and whether belong to odd number or even number time slot group with inspection called paging receiver.Because call terminal 32 is only handled the customer call with even number CAP sign indicating number during the even number time slot, during the odd number time slot, only handle customer call with odd number CAP sign indicating number, according to institute's distributed time slot paging receiver is divided into odd even time slot group.

At step 5C, check whether current time slots is the same with the time slot of called paging receiver.According to above hypothesis, be the even number time slot if distribute to the time slot of called paging receiver, just under the processed state of the calling of another called paging receiver that belongs to even number time slot group, send this beep-page message immediately.According to the number of the other message that will be sent out in same number of frames, whether decisions such as the length of each message send message immediately at corresponding time slot.If can send beep-page message in current time slots, this message will be in standby condition up to next even number time slot.Then beep-page message should be stored in (formation) in the memory.In a preferred embodiment of the invention.Got rid of such situation and supposed that beep-page message is sent immediately.

If at step 5c, the time slot of called paging receiver and n time slot are different, beep-page message are stored in the odd number time slot at step 5e and prepare in the formation.If at step 5c, it is the same with the n time slot, just carries out " beep-page message sends immediately " program at step 5d.After

step

5d or 5e, whether check to be the time that a new time slot sends beep-page message at step 5f.Even do not receive beep-page message at step 5a, also execution in step 5f.Just do not send the beep-page message of standby condition if also have at step 5e to being the time that a new time slot sends beep-page message.The same with even number (n) time slot, also can sense page message request at odd number time slot (n+1).But only be described in detail in the odd number time slot and prepare the operation that the message in the formation is handled being stored in the odd number time slot.

At step 5g, prefix and synchronization character are sent out.At step 5h, form the head group.In this case, the service bits state should be 1.At step 5i, search is stored in the beep-page message in the odd number time slot preparation formation.At step 5j, form the data set that comprises data address and data-message, and send data set at step 5k.

Fig. 6 is the flow chart of an explanation " beep-page message sends immediately " shown in Figure 5 program.

At step 6a, call terminal 32 checks whether sent the head group in corresponding time slot.If just should check that the service bits that is included in the head group is 0 or 1.This is because if service bits is 0, and paging receiver is power cutoff, although when service bits is 1 power cutoff not.Be sent out if service bits is 0 head group, just there is no need to send beep-page message.Therefore, check at step 6b whether service bits is 1.If be 0, beep-page message be stored in the even number time slot at step 6C and prepare in the formation.Send stored beep-page message at next even number time slot.

Simultaneously, if do not have the delivery header group at step 6a, if promptly if beginning to send the time or the prefix of prefix is sent out, just to form service bits be 1 head group and send after step 6d is sending prefix.Form the data set that comprises data address and data-message at step 6e.

Fig. 7 is the flow chart of an explanation according to the operating process of preferred embodiment of the present invention paging receiver.In standby condition, the controller 44 of paging receiver to 41 power supplies of RF device, is carried out initialization operation at step 7b at step 7a.In this case, the normal running timer was set to about 15 seconds, can normal running decoder 56, and make decoder keep timer to be released at the not operated decoder of corresponding time slot.At step 7c, a data/address is assigned to decoder 56, to receive head group and data set from the signal that receives by the RF device.Check whether detect leading address at step 7d.If detect, analyze a message at step 7e, see whether current time slots is its time slot.If current time slots is its time slot, just check the state of service bits at step 7f.Suppose that service bits is that 0 representative does not have data set to be sent out, service bits is 1 to mean have data set to be sent out.

If service groups is 0, just produces decoder inhibit signal DH and be set to a corresponding time slot, thereby turn-off the power supply of RF device 41 time period in this in the step 7g decoder retention time.At step 7h, check that decoder keeps timer.If decoder keeps the time-out that is provided with of timer, just suspend generation decoder inhibit signal DH at step 7i and offer common power.At step 7j, the normal operations timer is set and turns back to step 7d.

If at step 7f service bits is 1, just check whether detected data address at step 7k.If detect data address, just receive data-message from decoder in step 71.At the data-message that step 7m handles and storage receives.Show the data-message that receives and send by alarm 43 devices through display unit 45 at step 7n.Check whether mistake of setting-up time that the normal operations timer sees it in step 70.Even do not detect data address at step 7k, also execution in step 70.If setting-up time did not have, step 70 is returned step 7k.The fact that the time that is provided with of normal operations timer crosses means the time slots of permission mistake own.That is to say, if self time slot is the even number time slot, the fact that the time slots of permission own has been crossed means it has been a new odd number time slots of beginning, keep timer by driving decoder by the time that is provided with, decoder 56 will be operated at the next time slot except that it self time slot.

If do not detect leading address at step 7d, step 7d proceeds to step 7k and sees whether data address is detected.This is because have such situation during normal operations, loses and also detects data address even leading address has no the quilt of reason.

Fig. 8 A-8C is time slot and sequential organization, and the saving battery status of the paging receiver that is used for a time slot is described.Fig. 8 A explanation has the structure of a time slot of constant time span.Fig. 8 B illustrates a kind of state, when when detecting prefix and checking that the head group determines that a current time slots is it self time slot, normally provides power supply to the RF device.Fig. 8 represents a kind of state, and the power supply that offers the RF device when current time slots is not it self time slot is cut off.In this case, paging receiver does not receive data burst message at corresponding time slot, does not keep the receiver operation of operation as decoder.

Fig. 9 A-9C is a sequential chart, and the paging receiver that is illustrated as a plurality of time slots is saved the sequential chart of battery status.Fig. 9 A illustrates that each has the transformat of the time slot of constant time span.Fig. 9 B represents the battery consumption state when the time slot of paging receiver is the odd number time slot.Fig. 9 c represents the battery consumption state when the time slot of paging receiver is the even number time slot.In control method of the present invention, the power consumption of supposing traditional pagers is 100, only consumes 50% of conventional power.If service bits is 0, have only prefix to be detected, the RF device just is de-energized up to corresponding data sets or next time slot.When the power consumption of traditional paging receiver is 100, only consume 3.33% conventional power then.

As shown, when transmission had the time slot of constant time span, paging receiver was checked prefix and head group.If current time slots is not himself time slot, the RF device is outage just, and if himself time slot RF41 device just powers on, and therefore consuming cells just not when promptly current time slots is not himself time slot has just saved electric energy.

Figure 10 A-10C is the detailed structure of time slot.Figure 10 A represents to comprise the time slot group of 4 time slots.The structure of Figure 10 B explanation included head group in the even number time slot.The structure of Figure 10 C explanation included head group in the odd number time slot.

Reference symbol OTS1 and OTS2 represent the odd number time slot in Figure 10 A; ETS2 and ETS4 represent the even number time slot; B1-B31 is a data set.Reference symbol PR represents prefix data; HDB represents the head group.Suppose that each time slot is 15 seconds, a time slot group is one minute.

With reference to figure 10B, 2 gap information bit S0 and S1 are assigned to the message data of any frame of the head group that constitutes the odd number time slot.In a preferred embodiment of the invention, the time slot group comprises that the reason of 4 time slots is that 4 numerals are arranged, and for example 1,2,3,4 are represented by two bits.With reference to figure 10B and Figure 10 C,, define the time slot of information for odd number time slot even number time slot according to time slot in the time slot group although basic structure is mutually the same.In other words, because OTS1 is the odd number time slot, first frame among Figure 10 B has address date A1 and message data M1 and second frame does not have data.In Figure 10 C, because ETS4 is the even number time slot, second frame has address date A2 and message data M2 so first frame does not have data.Business information is a bit.Because night volume of transmitted data reduced, so when not having transfer of data, call terminal only transmits prefix and head group.Therefore can reduce battery consumption.For example, the business information bit is that 0 expression does not have data set.Therefore paging receiver is closed RF device 41.Because being 1 expression, the business information bit have data set, paging receiver to open RF device 41.AM/FM information is 1 bit, and hour information is 4 bits, and 10 minutes information is 4 bits, and 1 minute information is 4 bits, and inspection and bit are 4 bits.Check and bit is used to determine whether the header information data of 16 bits is wrong time slot just, business and AM/FM information, hour information, 10-minute information and 1-minute information.If the value that is added by 4 bit device is greater than 16, this value is just abandoned, and only sends a value between the 0-15.Paging receiver is by comparing to judge 16 significant bits and inspection and value whether information is effective.

The pocsag code of battery types is saved in Figure 11 explanation on the FLEX aggregate channel.First group of the prefix back is the head group that comprises synchronous code (SC) and 8 frames.One frame comprises 2 code words.One group comprises 17 code words.Second group and subsequently the group be data set.

Figure 12 represents the structure of the head group in the pocsag code shown in Figure 11.Suppose that the length that one minute (32 frame) is an one-period and a time slot is 15 seconds, 4 time slots are formed a time slot group.Each time slot has head group shown in Figure 12.2 gap information bits are assigned to the information data of the frame that constitutes the head group.For example, if the message data M1 of first frame that 0 head that is assigned to formation first time slot of 1 and the S1 of gap information bit S0 is organized will be understood that the data that are sent out belong to first time slot.

Except that gap information, AM/PM information comprises a bit, 4 bits hour information, 10 minutes information of 4 bits, 1 minute information of 4 bits, the folded and information of 4 bits.Therefore have distribute to hour minute and second information, to send precise time information, because the FLEX paging system adopts GPS information.Folded and bit is represented the operation format of FLEX type.The paging receiver detection timeslot number of result on aggregate channel and a folded and bit of organizing of prefix back, and shift to an earlier date the transmission time of sensing FLEX data.Therefore paging receiver can be closed RF device 41 when sending the FLEX data.

The state and the content of folded also bit of following table 1 and table 2 expression and time slot.

Figure 13 represents the Data Receiving form of 1-5FLEX aggregate channel.The 5FLEX aggregate channel has folded and information 4.Suppose one minute (32 frame) for one-period, the FLEX data were sent out and the POCSAG data were sent out in next 30 seconds in first 30 second (16 frame).The POCSAG data that are sent out are two time slots, each time slot 15 seconds, i.e. time slot 3 and time slot 4.From the viewpoint of POCSAG system, owing to send the FLEX data in corresponding to the time of time slot 1 and time slot 2, the POCSAG paging receiver need not operation in the time corresponding to time slot 1 and time slot 2.

The 4th aggregate channel has folded and information 3.During next 45 seconds, send the POCSAG data sending the FLEX data during first 15 seconds (8 frame).Send the POCSAG data at time slot 2-4.The 3rd FLEX aggregate channel has folded and information 2.Send the POCSAG data in the 1st 7.5 seconds (4 frame) transmission FLEX data and at ensuing 52.5 seconds.Send the POCSAG data at time slot 1-4.Only at 7.5 seconds sending time slots 1.Second aggregate channel has folded and information 1.Send the FLEX data at first 3.75 seconds and sent the POCSAG data at ensuing 56.25 seconds.Send the POCSAG data at time slot 1-4.Only at 11.25 seconds sending time slots 1.First FLEX aggregate channel has imbrication information 0.Send the FLEX data at first 1.875 seconds and sent the POCSAG data at ensuing 58.125 seconds.Only send the POCSAG data at the 1-4 time slot.Only at 13.125 seconds sending time slots 1.For every kind of situation, by being the length that 2k calculates the FLEX data with imbrication information k.As shown, the length of FLEX data is 1,2,4,8 and 16 frames.

Figure 14 is the oscillogram of the saving battery signal of POCSAG paging receiver on the FLEX aggregate channel.As shown in figure 14, waveform maintains a low state when receiving the FLEX data.In other words, when receiving the FLEX data, RF device 41 is closed to save battery.Can make this operation become possibility by the transmission of prior sensing FLEX data.For this reason, time slot S0 and the S1 that is included in the arbitrary frame of head group of Fig. 2 is detected.

Figure 15 is the process of the saving battery of a flowchart text paging receiver.At step 15a, the controller 44 of paging receiver provides a power supply to RF device 41, carries out initialization operation at step 15b.At step 15C, give decoder 56 to receive the head group and the data set of the signal that receives by RF device 41 leading address/data allocations.Decoder 56 sends to controller 44 by detect data address after detecting prefix with data-message.At step 15d, controller 44 checks whether detect leading address.If detect, just analyze a message at step 15e.Check at step 15f whether current time slots is last time slot.In a preferred embodiment of the invention, if timeslot number is 4 or bigger, just judge that current time slots is last time slot.Last time slot means send the FLEX data after corresponding time slot.At step 15g, decoder is set keeps keeping timer, after the constant time, to keep decoder 56.It is that a time was arranged before decoder 56 is held that decoder maintenance reservation timer is set.

At step 15h, check that whether decoder keeps keeping timer and see the time of setting mistake.If just produce decoder inhibit signal DH to close RF device 41 at step 15i.At step 15j decoder is set and keeps timer.Check time that is provided with that decoder keeps timer mistake whether at step 15k.If decoder keeps time-out is set, just stop to produce the decoder inhibit signal so that a normal power supply to be provided to the RF device in step 151.Afterwards, step 151 turns back to step 15d.At step 15k, controller 44 continues to check that decoder keeps timer up to the time mistake is set.

If detect leading address and be not last time slot in step 15f current time slots at step 15d, step 15f just proceeds to 15d.In this case, leading address will not be detected.This is because detected leading address.Therefore, the data address of leading address back will be detected.If do not detect leading address at step 15d, step 15d just proceeds to step 15m.

At step 15m, check whether detect data address.If detected data address, just receive data-message from decoder at step 15n.Processed and the storage of the data-message that receives at step 15o.Send the data-message that is received by controlling display unit 45 and alarm device 43 Visual Display and the sense of hearing.After step 15p,, see time that is provided with that decoder keep to keep timer mistake whether with regard to execution in step 15h if perhaps do not detect data address at step 15m.

As a result, when being the FLEX time-like by checking that prefix and head are organized the data type that is obtained, the POCSAG paging receiver that uses in aggregate channel is closed the RF device, and is that the POCSAG time-like is just opened the RF device in data type only.

Although described the present invention, those skilled in the art will appreciate that under the condition that or else deviates from the desired scope and spirit of the present invention of claim and can carry out various modification with reference to preferred embodiment.

11., it is characterized in that described particular type is a kind of POCSAG type as the equipment of claim 10.

12. equipment as claim 11, it is characterized in that described call terminal will be converted to FLEX or pocsag code by the beep-page message that public switched telephone network (PSTN) receives according to the channel operation type of combination, determine accurate time slot by using, and during corresponding time slot, described FLEX or pocsag code are being sent to described paging receiver by base station apparatus from the information of global positioning system reception.

13. equipment as claim 12, it is characterized in that, the state of the time slot that described controller repeats with constant time span by the timer sensing that operates in wherein according to external clock, according to the transmission time of a detected timeslot number sensing POCSAG data of organizing, and at decoder inhibit signal of the generation of the time except that the transmission time of described POCSAG data.

14. equipment as claim 13, further comprise a decoder, be used for the data hardwood is decoded into the form of initial data, and produce a signal and be used to make described saving battery controller when the described decoder inhibit signal of input, cut off the power supply that offers described radio frequency device.

15. equipment as claim 13, it is characterized in that, described controller is provided with a decoder and keeps timer when producing described decoder inhibit signal, if described timer time-out is set, described controller produces a decoder and keeps release signal to receive the pocsag code of next time slot.

16. the equipment as claim 10 is characterized in that, described head group comprises the bit that is used for determining the aggregate channel action type.

17. be used for saving the method for battery at the beep-pager that a decoder that the data hardwood is decoded into original beep-page message is arranged, judge according to the timeslot number that is included in the head group whether a data set is the POCSAG data, and communicate by letter with call terminal by aggregate channel, said method comprising the steps of:

(a) provide a power supply to the wireless frequency device, and distribute a data address that is used to receive the leading address of head group and is used to receive data set for described decoder;

(b) check whether detect leading address or data address;

(C) just keep described decoder and the time that a decoder keeps timer is set if having only leading address to be detected;

(d) check that described decoder keeps the time of timer, if the setting-up time that described decoder keeps timer mistake just discharges the retention time of described decoder and turns back to described step (b).

18., it is characterized in that described step (c) may further comprise the steps as the method for claim 17:

(e) if detected leading address, just an inspection message sees whether current time slots is last time slot;

(f), just set the time that a decoder keeps keeping timer if current time slots is last time slot;

(g) check that whether described decoder keeps keeping timer and see described setting-up time mistake, and if current time slots be not the setting-up time mistake not that last time slot or described decoder keep keeping timer, just turn back to described step (b);

(h) if the setting-up time that described decoder keep to keep timer mistake just turns back to described step (c).

19., further comprise step as the method for claim 18, if be to detect data address under the state of last time slot in current time slots, just receive data-message from described decoder, handle and also show the data-message that receives, and return described step (g).
