In addition, as shown in Figure 3, mobile communication control station CS is connecting storage server SV.
This storage server SV is used for storing the one-way communication service data that the source terminal of posting a letter sends when communication service judgment means 321 concludes that the source terminal of posting a letter that for example connects by Department of Communication Force 36 requires one-way communications such as audio communication or facsimile, data communication to serve.
Mobile communication control station CS has communication control unit 323, be used for carrying out selectively according to the intermittent receiving pattern of concluding by intermittent receiving mode determining apparatus 322 and by communication service judgment means 321 conclude go into to exhale the time the communication service kind, that utilizes storage server SV goes into to exhale control, and comprise the intermittent receiving pattern the change order go into to exhale control.
Utilize storage server SV go into to exhale control be taken place to require when mobile communication apparatus to the intermittent receiving pattern that is set at long period T2 this one-way communication service such as facsimile go into to exhale the time, mobile communication apparatus is not gone into to exhale processing, but call out storage server SV, will deposit storage server SV from the facsimile data that calling side sends in.In addition, meanwhile, when from mobile communication apparatus PS1, PS2 ... sending Xiang Benji inquires about when having or not the information of storing data, judge and have or not this storage data, when these storage data, read this data from storage server SV, and give the query source mobile communication apparatus.
Comprise the intermittent receiving pattern change order go into to exhale control be when to mobile communication apparatus PS1, the PS2 of the intermittent receiving pattern that is set at long period T2 ... taken place to require this two-way communication service such as voice communication or video telephone go into to exhale the time, sending the intermittent receiving pattern to the mobile communication apparatus of going into to exhale a side is the indication that short period T1 pattern is used from long period T2 mode altering, thereby is short period T1 pattern with the intermittent receiving mode altering of mobile communication apparatus.In addition, within a certain period of time, the indication information of calling out is once more returned to the caller.
Secondly, utilize Fig. 6, the working condition of the system that as above constitutes is described to flow chart shown in Figure 9.
Mobile communication apparatus PS1, PS2 ... in, according to timer 27 timer times, set short period T1 (T1=1 second) intermittent receiving pattern by day for, for example automatically set long period T2 (T2=480 second) intermittent receiving pattern for from 7 of mornings, 10 of nights to next day.The operator can at random set its switching instant by the operation of operating portion 26.In addition, the setting of above-mentioned intermittent receiving pattern also can at random be set by the operation of operating portion 26 by the operator.
Mobile communication apparatus PS1, PS2 ... in, receiving part 231 is in when waiting for accepting state, according to the intermittent receiving pattern of above-mentioned setting, goes into to exhale the intermittent receiving work of control channel.
In addition, intermittent receiving pattern notice portion 232 utilizes the control channel of posting a letter, by base station BS 1, BS2, information notice mobile communication control station CS with the intermittent receiving pattern of above-mentioned setting, in mobile communication control station CS, with the intermittent receiving pattern of this notice respectively with mobile communication apparatus PS1, PS2, store accordingly, communication control unit 323 is with the cycle corresponding with the intermittent receiving pattern of above-mentioned storage simultaneously, to waiting for the mobile communication apparatus PS1 in receiving, PS2, set and to go into to exhale control channel, use this to go into to exhale control channel to go into to exhale the transmission of signal etc.
Under this state, if from other communication network NW issue the mobile communication apparatus PS1 that accommodates the native system go into to exhale signal to arrive the time, in mobile communication control station CS, as shown in Figure 6, at first in step 6a, intermittent receiving mode determining apparatus 322 judges that the intermittent receiving pattern of setting now among the mobile communication apparatus PS1 is short period T1 pattern or long period T2 pattern.
Then,, then directly move to step 6b, go into to exhale signal what this transmission comprised mobile communication apparatus PS1 identiflication number if what set is short period T1 intermittent receiving pattern.At this moment, go into to exhale the transmitting time of signal to be set to distribute to that group's short period T1 pattern is used under the mobile communication apparatus PSi goes into to exhale control channel.For example, if mobile communication apparatus PSi belongs to the 1st group now, as shown in Figure 4, set the paging channel P1 in each subframe.The location registration area that mobile communication apparatus PSi constitutes with the radio district by a plurality of base stations is a unit, and oneself location is registered in the system.Therefore, the signal of going into to exhale of giving mobile communication apparatus PSi just sends the whole base stations in the location registration area of this mobile communication apparatus registration present position.Receive into the mobile communication apparatus of exhaling signal since receive only from the radio district at present place go into to exhale signal, answer signal so transmit into to echo by this base station.Like this, what sent above-mentionedly goes into to exhale signal, in step 6c.After mobile communication apparatus PSi is by base station BS j relaying, be fed to mobile communication apparatus PSi.
As shown in Figure 4, in mobile communication apparatus PSi, carry out the intermittent receiving work of short period T1 pattern among the 1st crowd of paging channel P1 under this machine.And, under this state,, then moving to step 6e from step 6d if the signal of going into to exhale of this machine of sending to arrives, at this moment mobile communication apparatus PSi transmits into to echo by control channel and answers signal.Receive this go into to echo answer signal after, move to step 6g from step 6f, at this moment base station BS j selects idle channel from a plurality of communication channels, and with going into to exhale control channel to notify mobile communication apparatus PSi with this idle channel.
After mobile communication apparatus PSi received this channel specified notification, the communication channel with this machine in step 6h switched to this communication channel, and sent ring sound etc. and send into exhaling notice to the user in step 6i.Under this state, carry out off-hook then and monitor, after the user confirms to exhale notice and carries out the off-hook operation, in step 6k, off hook signal is sent to other communication network NW in the source of posting a letter after by base station BS j relaying at step 6j.Consequently post a letter distant terminal and above-mentioned posting a letter couples together by link between the mobile communication apparatus PSi of source, just can communicate by letter between the two later on.
, suppose since for example the mains switch of mobile communication apparatus PSi disconnect, or moved on to beyond the service area of base station, cause and answer signal into concord and can not be sent back to the base station.If like this, 6f moves to step 61 from step, and the base station report of at this moment will not collecting mail sends to mobile communication control station CS.Mobile communication control station CS confirms this report at step 6m after receiving this report of not collecting mail, and just transfers to hereinafter described storage control then.
In addition, suppose that the intermittent receiving pattern of setting among the mobile communication apparatus PSi of the side of exhaling is a long period T2 pattern.At this moment mobile communication control station CS concludes if still go into to exhale control, might can not go into to exhale work normally because of connection delay is excessive, thereby changes storage control or the control of intermittent receiving periodic change that utilizes storage server SV into.
Promptly, as shown in Figure 7, in mobile communication control station CS, at first in step 7a, judge that by communication service judgment means 321 communication service of the source terminal requirement of posting a letter is two-way simultaneous communication services such as phone or video telephone, or audio communication or one-way communication services such as facsimile, data communication.Then, if the one-way communication service then moves to step 7b, judge whether mobile communication apparatus PSi is the subscriber of stores service, if not the subscriber, moves to step 7g, at this moment cuts off processing.In addition, at this moment send busy(-back) tone to the source terminal of posting a letter.
Secondly, suppose that now mobile communication apparatus PSi is the subscriber of stores service.At this moment, in mobile communication control station CS, communication control unit 323 carries out later storage control.That is, at first move to step 7c, corresponding to going into to exhale signal, connect storage server SV, will impel the guidance information etc. of transmission information etc. to give the source terminal of posting a letter at step 7d.The information that to send here from the calling side terminal in step 7e etc. deposits storage server SV in then.Storage moves to step 7g from step 7f after finishing, and cuts off processing, returns the wait accepting state.
Disconnect or because of having moved on to service area in addition under out of contior state at the power supply of mobile communication apparatus PSi, as shown in Figure 8, among step 8a, receive on one side from base station BSj by the signal of going into to exhale control channel to send, among step 8bs monitor whether this machine return controllable state on one side.In addition, suppose that at this moment mobile communication apparatus PSi is in long period T2 intermittent receiving pattern, then as shown in Figure 5, above-mentionedly go into to exhale in the control channel and send by what the signal of going into to exhale control channel to carry out sent that only group's long period T2 pattern is used under this machine of distributing to.
Under this state, for example the mains switch of mobile communication apparatus PSi is connected, or mobile communication apparatus PSi gets back in the service area, therefore, when receive from base station BS j go into to exhale control channel after, conclude and get back to controllable state, move to step 8c, judge at this moment whether this machine has arranged stores service.Then, when having arranged stores service, after just switching goes into to exhale control channel in step 8d, move to step 8e, at this moment send stores service visiting demand signal.In addition, when not arranging stores service, do not carry out the transmission of above-mentioned visiting demand signal, receive control and directly transfer to common wait.That is, do not carry out the transmission of invalid signals, so the communication of control channel can be obstructed.
After the above-mentioned stores service visiting demand signal relaying that warp carries out in step 8f in base station BS j sends mobile communication control station CS to, move to step 8h from step 8g, at this moment mobile communication control station CS judges whether the data of issuing above-mentioned visiting demand source mobile communication apparatus PSi have deposited storage server SV in.Then, tentation data deposits in, moves to step 81, at this moment above-mentioned visiting demand source mobile communication apparatus PSi is connected storage server SV, gives base station BSj with the appointment indication of communication channel in step 8m.Indicate storage server SV to send stored information then.
In step 8n, base station BSj selects idle communication channel after receiving the appointment indication of above-mentioned communication channel from a plurality of communication channels, and notice mobile communication apparatus PSi uses this free time communication channel as calling out control channel.After mobile communication apparatus PSi receives the appointment of above-mentioned communication channel, in step 80, will call out control channel and switch to this communication channel, move to step 8q then, receive the stored information of sending here from storage server SV.
So, carry out sending the storage data to the storage inquiry of mobile communication control station CS and from the storage server SV corresponding to mobile communication apparatus PSi with this inquiry from mobile communication apparatus PSi.
Secondly, the change control in intermittent receiving cycle is described.
In step 9a shown in Figure 9, when communication service judgment means 321 concluded that the communication service of the source terminal requirement of posting a letter is two-way simultaneous communications such as phone or video telephone service, later mobile communication control station CS just carried out the change control in intermittent receiving cycle.That is, as shown in Figure 9, at first in step 9a, use and go into to exhale control channel to send the change index signal in intermittent receiving cycle.This change index signal through after arriving then in carrying out, moves to step 9d from step 9c in step 7b in base station BS j, mobile communication apparatus PSi is short period T1 pattern with the intermittent receiving pattern of setting in this machine from long period T2 mode altering.Then, in step 9e, will send back to, and return then and wait for the reception state of a control the answer signal of intermittent receiving mode altering.
This answer signal at base station BS j through after arriving then in carrying out among the 9f in the step, move to step 9h from step 7g, at this moment mobile communication control station CS stores above-mentioned intermittent receiving pattern after changing corresponding to mobile communication apparatus PSi, returns then and waits for the reception state of a control.
In addition, mobile communication control station CS will impel the guidance information of conversation to give the source terminal of posting a letter when the change control of carrying out the above-mentioned intermittent receiving cycle or after the control end.For example adopt as this guidance information: " existing just the preparation collected mail.I'm sorry, ask conversation after 10 minutes." printed words.In addition, this guidance information also can adopt from the loud speaker of the terminal of posting a letter and send the acoustic information of amplification, also can demonstrate forms such as display message at display part 24.In addition, when adopting this display message, make LED flash simultaneously or produce buzzing, as long as the user is discovered really.
In addition, go into to exhale the guidance information of usefulness to be given mobile communication apparatus PSi from mobile communication control station CS with the change index signal in intermittent receiving cycle into the side of exhaling.When mobile communication apparatus PSi receives above-mentioned guidance information, after the change control in intermittent receiving cycle finishes, for example show above-mentioned guidance information at display part 24.For example adopt as this guidance information: " can converse soon.Just a moment,please." printed words.In addition, in the time of also can be with the demonstration of above-mentioned guidance information, the short time be sent the buzz different with going into to exhale buzzing.If adopt this mode, then the user of mobile communication apparatus just can wait for going into to exhale.
As mentioned above, under this example, mobile communication apparatus PS1, PS2 ... intermittent receiving pattern with 2 kinds of different cycles, these patterns are configured to difference in time and automatically switch, and the user can set arbitrarily by keyboard operation simultaneously.Therefore, for example at the traffic few night, but therefore the 2 intermittent receiving work of executive chairman's period T can suppress the consumption electric power at night, can further extend the life of a cell.
And, with mobile communication apparatus PS1, PS2 ... the middle intermittent receiving pattern notice mobile communication control station CS that sets, the intermittent receiving pattern that mobile communication control station CS will notify by each mobile communication apparatus PS1, PS2 ... store, with the cycle corresponding, carry out sending by the signal of going into to exhale control channel to carry out to waiting for the mobile communication apparatus in receiving with the intermittent receiving pattern of above-mentioned setting.Therefore, with this intermittent receiving pattern time corresponding in, can to each with mobile communication apparatus PS1, PS2 ... go into to exhale the transmission of signal etc., send, can improve the effective rate of utilization of going into to exhale control channel thereby can not carry out useless signal.
In this example, when going into to exhale signal to arrive, judge the kind of going into to exhale the desired communication service of signal respectively and go into the intermittent receiving pattern of setting among the mobile communication apparatus PSi of the side of exhaling, when what set among the mobile communication apparatus PSi that goes into the side of exhaling is long period T2 intermittent receiving pattern and when going into to exhale the service of one-way communications such as semaphore request audio communication or facsimile, go into to exhale signal to be connected with above-mentioned storage server SV, will store away from the data of calling side.Therefore,, can not finish to call out to the signal of going into to exhale that requires the one-way communication service yet, can reply reliably immediately, and can receive data owing to producing big connection delay even set long period T2 intermittent receiving pattern among the mobile communication apparatus PSi.Therefore, the caller needn't converse etc., can keep caller's convenience to heavens thus.
In addition, after the mobile communication apparatus PSi energized or when getting back in the service area, from mobile communication apparatus PSi mobile communication control station CS is returned in the visiting demand of stores service, after mobile communication control station CS receives this visiting demand, judged whether to store the data of giving this mobile communication apparatus PSi.Then, when storing, just storage server SV and above-mentioned mobile communication apparatus PSi are coupled together, so that carry the storage data.Therefore, mobile communication apparatus PSi can automatically know the storage data that have or not to this machine after energized or when getting back in the service area, and when the storage data are arranged, can automatically receive these storage data.
Moreover, in this example, when what set among the mobile communication apparatus PSi that goes into the side of exhaling is long period T2 intermittent receiving pattern and when going into to exhale two-way simultaneous communications such as semaphore request phone or video telephone service, give mobile communication apparatus PSi from mobile communication control station CS with the change in intermittent receiving cycle indication, so be short period T1 pattern from long period T2 mode altering with the intermittent receiving pattern.In addition, at this moment, with the guidance information notification call person who converses within a certain period of time.
