Embodiment
With reference to accompanying drawing embodiments of the present invention are described.
Mobile body communication system 1 in the embodiment of the present invention, as shown in Figure 1, it comprises: a plurality of base station apparatus 2, mobile station apparatus 3 and communication network 4 constitute.Base station apparatus 2 communicates with general communication network 4 and mobile station apparatus 3.
Base station apparatus 2, as shown in Figure 2, it comprises: control part 20, wireless communication part 21, storage part 22, network interface portion 23 constitute.Control part 20 is controlled each one of base station apparatus 2, and the execution processing relevant with conversation or data communication.Wireless communication part 21, has antenna, it carries out following processing, promptly or respectively receive from the voice signal of mobile station apparatus 3 or communication and it is carried out demodulation and outputs to control part 20, perhaps according to from the indication of control part 20 inputs, after modulating with dividing into groups etc., export by antenna from the voice signal of control part 20 inputs or communication with grouping etc. is back.Storage part 22 comes work as the working storage of control part 20.In addition, this storage part 22 is preserved and relevant program or the parameter of being carried out by control part 20 of various processing.Network interface portion 23, be connected with communication network 4, itself or receive from the voice signal of communication network 4 or communication and it outputed to control part 20 with after the grouping etc., perhaps communication network 4 is sent voice signals or communication with dividing into groups etc. according to the indication of control part 20.
Mobile station apparatus 3 is the terminal installation that has known mobile phone now or use in mobile body communication systems such as PHS, and passes through the transmitting-receiving electric wave between the base station apparatus 2, comes to communicate with base station apparatus 2.In addition, telecommunication network 4 also can be the switch network of mobile body communication system, under mobile body communication system 1 is situations such as communication system under the IP phone, can be the TCP/IP net.
The wireless communication part 21 of base station apparatus 2, as its original function, as shown in Figure 6, comprise respectively a plurality of transmission-receiving function 130-n of portion of using as R-T unit (n=1,2 ...) constitute.In addition, though among this figure for simplicity, only drawn 130-1 of transmission-receiving function portion and the transmitting-receiving kinetic energy 130-2 of portion, the 130-n of transmission-receiving function portion can be arbitrarily.Then, the 130-n of transmission-receiving function portion comprises: data communication section 131-n, radio control section 132-n, no wire casing control part 134-n and receiving and transmitting part 135-n constitute, and receiving and transmitting part 135-n comprises at least one antenna formation.In addition, in receiving and transmitting part 135-n, be painted with 4 antennas among this figure.This is expression is used this antenna as adaptive array antenna a situation.By using adaptive array antenna, can send the strong electric wave of directive property, and can carry out the reception of highly directive.
At first, illustrate that the processing of docking the time receiving describes.Receiving and transmitting part 135-n receives in antenna from the modulating wave of the given frequency of mobile station apparatus 3 transmissions, this reception ripple is carried out frequency inverted, and output among the no wire casing control part 134-n.No wire casing control part 134-n, obtains the reception ripple of calling out under the unit at time slot of its reception ripple by extracting input out, and outputs among the radio control section 132-n.Radio control section 132-n, calling unit's reception ripple down of input carried out demodulation after, acquisition received signal, and output to data communication section 131-n.Then, data communication section 131-n outputs to control part 20 with the received signal of importing.
Below, the processing during to transmission describes.Data communication section 131-n by the transmission signal from control part 20 input audio signals or the grouping of communication usefulness etc., and outputs to radio control section 132-n.Radio control section 132-n modulates the transmission signal of importing from data communication section 131-n, and this modulating wave is outputed to no wire casing control part 134-n.No wire casing control part 134-n distributes the processing of time slot to the calling as this modulating wave, and outputs to receiving and transmitting part 135-n.Receiving and transmitting part 135-n is transformed into given frequency with frequency of modulated wave, and utilizes antenna to sending between radio zone.Then, the modulating wave of this transmission is by reception, demodulation in mobile station apparatus 3.
As above, as original processing, 130-1 of transmission-receiving function portion and the 130-2 of transmission-receiving function portion irrespectively carry out the transmitting-receiving of signal each other.And receiving and transmitting part 130-n separately carries out frequency translation with mutually different transmission frequency when sending, thereby even simultaneously from the also mutually noninterfere each other of antenna transmission electric wave.In addition, 130-n of transmission-receiving function portion separately and mutually different mobile station apparatus 3 communicate.Therefore, when receiving, also receive the mutually different electric wave of receive frequency.
Fig. 7 is the figure that schematically illustrates the relation of frequency and time slot.As shown in the figure, the time slot Tn (n=0～3) that is sent by receiving and transmitting part 135-1 and the time slot Rn (n=0～3) of reception respectively by time division multiplexing, will send also time division multiplexing of groove and receiving slit by many signals of time-division again.For receiving and transmitting part 135-2 too.Then, each time slot, as shown in the drawing, send or receive with frequency f n (n=0～7).That is, in each time slot and each time slot among the receiving and transmitting part 135-2 among the receiving and transmitting part 135-1, use different frequencies respectively.In more detail, the different time slots owing to receiving and dispatching simultaneously can produce interference each other, therefore can not use identical frequency.Here, in the example of Fig. 7, for example, therefore use the f1 of different frequency and f5 to send respectively owing to send groove T1 and send the time slot that groove T5 uses transmission simultaneously.
In addition, as shown in Figure 7, not in the groove of receiving and dispatching simultaneously (for example T0 and T5), though even without using different frequencies on principle, can not interfere yet, but, so use different frequencies here in fact owing to existing because of the situation of interfering appears in phase shift etc.
By like this, owing to can carry out the distribution of frequency, i.e. the base station apparatus 2 that for example traffic is big, the quantity by the 130-n of transmission-receiving function portion increases, and the spendable time slot in frequency division multiplexing and the time-multiplexed hybrid system increases; The quantity that the base station apparatus 2 that the traffic is little passes through the 130-n of transmission-receiving function portion reduces, and spendable time slot tails off, thereby can effectively utilize limited frequency resource,
Here, in the big base station apparatus of the traffic, though can increase channel, even the traffic neither be always very big in the big base station apparatus of the traffic, at this moment just can not effectively utilize R-T unit.In addition, the electric wave that the signal post that is undertaken by certain receiving and transmitting part 135-n produces perhaps becomes interference wave in mobile station apparatus 3 or other receiving and transmitting part 135-n, perhaps produce the phasing (phasing) under reflected wave or the Doppler effect.
Fig. 3 is to be used for preventing the control part 20 of base station apparatus 2 of the present embodiment that this situation takes place and the FBD (function block diagram) of wireless communication part 21.As shown in the figure, wireless communication part 21, comprise a plurality of transmission-receiving function 30-n of portion (n=1,2 ...) constitute.In addition, though among this figure for simplicity, only be painted with 30-1 of transmission-receiving function portion and the 30-2 of transmission-receiving function portion, the 30-n of transmission-receiving function portion can be arbitrarily.Then, the 30-n of transmission-receiving function portion on function by: data communication section 31-n, radio control section 32-n, no wire casing control part 34-n, receiving and transmitting part 35-n constitute.Wireless communication part 21 also comprises groove selection portion 33, frequency setting portion 36 and sends signal deciding portion 37 formations.In the following in addition explanation,, in fact also can use the 30-n of transmission-receiving function portion more than 3 though be that example explains only for simplicity with 30-1 of transmission-receiving function portion and the 30-2 of transmission-receiving function portion.
At first, the processing in butt joint time receiving describes. at the beginning, control part 20 is selected, determine to come at least one side of its receive frequency that uses is separately set as same frequency according to the receive frequency that receiving and transmitting part 35-1 and receiving and transmitting part 35-2 are used separately, still come at least one side of its receive frequency that uses is separately set as different frequency according to the receive frequency that receiving and transmitting part 351 and receiving and transmitting part 35-2 are used separately. in addition, the receive frequency that so-called receiving and transmitting part 35-1 and receiving and transmitting part 35-2 use separately is the situation of same frequency, be meant with receiving and transmitting part 35-1 and receiving and transmitting part 35-2 by a situation that electric wave receives that sends from a mobile station apparatus 3. so long as can receive identical getting final product on this degree of electric wave of a mobile station apparatus 3 transmissions, be not proper same frequency.
Then, selecting under the situation about setting at least one side of the mode of different frequencies, receive frequency that it is used respectively according to the receive frequency that receiving and transmitting part 35-1 and receiving and transmitting part 35-2 are used respectively, base station apparatus 2, by with reference to above-mentioned Fig. 6 and the illustrated identical processing of Fig. 7, receive.That is, by frequency division multiplexing, make receiving and transmitting part 35-1 and receiving and transmitting part 35-2 independently of one another communicate with mobile station apparatus 3.
On the other hand, under the situation that the receive frequency of selecting to use respectively according to receiving and transmitting part 35-1 and receiving and transmitting part 35-2 is set as at least one side of the mode of same frequency, receive frequency that it is used separately, 20 pairs of frequency setting portions 36 of control part indicate: according to the receive frequency that is utilized separately by receiving and transmitting part 35-1 and receiving and transmitting part 35-2 is the mode of same frequency, changes at least one side in the receive frequency that is utilized in the reception under receiving and transmitting part 35-1 and the receiving and transmitting part 35-2.Then, receive the frequency setting portion 36 of this indication,, change to for example identical receiving and transmitting part 35-1 and the employed receive frequency of receiving and transmitting part 35-2.At this moment, frequency setting portion 36 can all change receiving and transmitting part 35-1 and the employed receive frequency of receiving and transmitting part 35-2, also can be only a side be wherein changed.As concrete processing, can be in receiving and transmitting part 35-1 and receiving and transmitting part 35-2, rewrite the receive frequency of the frequency storage list of reference in the frequency inverted.That is, for example the frequency of the synchronizing signal of using by with frequency inverted the time is changed according to the receive frequency of storing in the said frequencies storage list, just can change receive frequency.More particularly, for example can the reference frequency among the PLL (Phase Locked Loop, i.e. phase-locked loop) be changed.
In addition, under the situation that the mode that is harmonious according to receive frequency that makes receiving and transmitting part 35-2 and the already used receive frequency of receiving and transmitting part 35-1 changes, also can change by a receive frequency receiving and transmitting part 35-2.And, can make as long as change once then need not per call and changing.That is, can make once under the situation of above-mentioned change indication, this change is stored as the modification information of representing this change with receiving and transmitting part 35-1 and receiving and transmitting part 35-2, and before new indication occurring, keep this change state and carry out frequency inverted at control part 20.Frequency setting portion 36 in addition also can be to frequency f n illustrated in fig. 7 (n=0～7), be the frequency of each time-multiplexed time slot, once changes.
Like this, frequency setting portion 36 can according to the receive frequency that uses among receiving and transmitting part 35-1 and the receiving and transmitting part 35-2 as the mode of same frequency, come each receive frequency is set, and its receiving and transmitting part 35-1 and receiving and transmitting part 35-2 can receive an electric wave that sends from a mobile station apparatus 3.Moreover this moment, may produce phase shift, or field intensity can become difference.In this case, base station apparatus 2 by utilizing the diversity reception of 2 groups of antennas with receiving and transmitting part 35-1 and receiving and transmitting part 35-2, obtains more high-precision received signal.Then, receiving and transmitting part 35-1 and receiving and transmitting part 35-2 receive the modulating wave that is sent by a mobile station apparatus 3 respectively, and respectively this reception ripple are carried out frequency inverted, and it is outputed to no wire casing control part 34-1 respectively and does not have wire casing control part 34-2.
No wire casing control part 34-1 and do not have wire casing control part 34-2 extracts out by the time slot of the reception ripple that will import, obtains to call out the reception ripple under the unit, and outputs to radio control section 32-1 and radio control section 32-2 respectively.Radio control section 32-1 and radio control section 32-2 will obtain received signal after the reception ripple demodulation of calling out under the unit then.At this moment, groove selection portion 33 can be selected a side according to the indication from control part 20 in the reception ripple that is input to radio control section 32-1 and radio control section 32-2, be input among the radio control section 32-1 again.The processing of this selection is the processing of being undertaken by diversity reception, except that selecting, can also be with the demodulated received ripple be synthetic separately by radio control section 32-1 and radio control section 32-2, and the reception ripple that will synthesize is input among the radio control section 32-1 again.In addition, the available time slot unit of processing that is undertaken by diversity reception carries out.
Radio control section 32-1, the received signal that obtains after can the reception ripple with this input of demodulation outputs to data communication section 31-1, and data communication section 31-1 outputs to control part 20 with the received signal of input.
In addition, select according to the mode of the receive frequency that receiving and transmitting part 35-1 and receiving and transmitting part 35-2 are used respectively at control part 20 as different frequency, under the situation of coming at least one side in its receive frequency that uses is separately set, control part 20, can be by according to the mode of the receive frequency that receiving and transmitting part 35-1 and receiving and transmitting part 35-2 are used respectively as different frequency, come at least one side in its receive frequency that uses is separately set, thereby carry out new indication to turn back to the processing that communicates with the frequency division multiplexing among receiving and transmitting part 35-1 and the receiving and transmitting part 35-2 and a plurality of mobile station apparatus 3.In this case, receiving and transmitting part 35-1 and receiving and transmitting part 35-2 can delete the above-mentioned modification information of being stored, and write new frequency in the frequency storage list.In addition, groove selection portion 33 will be selected to be input to a side in the reception ripple of radio control section 32-1 and radio control section 32-2, be input to processing termination among the radio control section 32-1 again.
So, can effectively utilize the R-T unit in the base station apparatus 2, and can utilize the diversity reception of 2 groups of antennas that R-T unit 35-1 and R-T unit 35-2 have, receive signal from mobile station apparatus 3 with high sensitivity more.
Below, the processing during to transmission describes.Control part 20 at the beginning, select according to the communication quality data in the mobile station apparatus 3 or the traffic in this base station apparatus 2, determine to come at least one side of its transmission frequency of using is separately set as same frequency according to the transmission frequency that receiving and transmitting part 35-1 and receiving and transmitting part 35-2 are not used, still according to the transmission frequency that receiving and transmitting part 35-1 and receiving and transmitting part 35-2 are used respectively as different frequency, come at least one side of its transmission frequency of using is separately set.In addition, the transmission frequency that so-called receiving and transmitting part 35-1 and receiving and transmitting part 35-2 use respectively is the situation of same frequency, is meant that the transmission signal that is sent with receiving and transmitting part 35-1 and receiving and transmitting part 35-2 can be received by a mobile station apparatus 3.That is, so long as can receive identical getting final product on this degree, not necessarily proper identical frequency by a mobile station apparatus 3.
Then, under selecting situation about setting according at least one side of the transmission frequency that receiving and transmitting part 35-1 and receiving and transmitting part 35-2 are used respectively for different frequencies, in the transmission frequency coming it is used separately, base station apparatus 2 is used and is sent with reference to the identical processing of the processing of the explanation of above-mentioned Fig. 6 and Fig. 7.That is, by frequency division multiplexing, receiving and transmitting part 35-1 and receiving and transmitting part 35-2 communicate with many mobile station apparatus 3 independently of one another.
On the other hand, under selecting situation about setting according at least one side of the transmission frequency that receiving and transmitting part 35-1 and receiving and transmitting part 35-2 are used respectively as same frequency, in the transmission frequency coming it is used separately, 20 pairs of control parts send signal deciding portion 37 and send indication, according to the signal of the signal deciding that is sent by the 30-1 of transmission-receiving function portion by the 30-2 of transmission-receiving function portion transmission.
At first, data communication section 31-1 from the transmission signal of control part 20 input audio signals or the grouping of communication usefulness etc., and outputs to radio control section 32-1.At this moment, sending signal deciding portion 37 20 pairs of control parts sends under indication, the situation of signal deciding according to the signal of the 30-2 of transmission-receiving function portion transmission of foundation by the 30-1 of transmission-receiving function portion transmission, send signal deciding portion 37, from data communication section 31-1, obtain above-mentioned transmission signal, and the transmission signal that should send by the 30-2 of transmission-receiving function portion according to this transmission signal deciding of obtaining, and the transmission signal that this should send is input to data communication section 31-2.In addition, preferably the transmission signal that should be sent by the 30-2 of this transmission-receiving function portion is identical with the transmission signal that obtains from data communication section 31-1.Then, data communication section 31-2 outputs to radio control section 32-2 with the transmission signal of this input.Moreover at this moment, also can make control part 20 that input does not send signal to data Department of Communication Force 31-2.
Radio control section 32-1 and radio control section 32-2, the transmission signal modulation of input is respectively formed modulating wave, and output to no wire casing control part 34-1 respectively and do not have wire casing control part 34-2. then, no wire casing control part 34-1 and do not have wire casing control part 34-2, the processing that the calling of modulating wave as input is respectively distributed time slot. at this moment, preferred wireless groove control part 34-1 and do not have wire casing control part 34-2, distribute identical time slot. and, no wire casing control part 34-1 and do not have wire casing control part 34-2, for receiving and transmitting part 35-1 and receiving and transmitting part 35-2, the calling of time slot is distributed in output respectively.
Here control part 20, frequency setting portion 36 is indicated: according to for the transmission signal that sends respectively by receiving and transmitting part 35-1 and receiving and transmitting part 35-2, in a mobile station apparatus 3 receivable mode, in the transmission frequency of utilizing among receiving and transmitting part 35-1 and the receiving and transmitting part 35-2, at least one side changes.More particularly, control part 20 is indicated frequency setting portion 36, according to the mode of the transmission frequency that receiving and transmitting part 35-1 and receiving and transmitting part 35-2 are used respectively as same frequency, comes at least one side in its transmission frequency of using is separately set.Then, receive the frequency setting portion 36 of this indication, receiving and transmitting part 35-1 and the employed transmission frequency of receiving and transmitting part 35-2 are changed, make it to become for example identical frequency.As concrete processing, can in receiving and transmitting part 35-1 and receiving and transmitting part 35-2, rewrite the transmission frequency of the frequency storage list of reference in the frequency translation.More particularly, for example can the reference frequency among the PLL (Phase Locaked Loop) be changed.In addition, change under the situation about being harmonious, can a transmission frequency change receiving and transmitting part 35-2 with the already used transmission frequency of receiving and transmitting part 35-1 in frequency with receiving and transmitting part 35-2.In addition, can only once change, and each calling not changed.That is, when control part 20 sends once above-mentioned change indication, by receiving and transmitting part 35-1 and receiving and transmitting part 35-2 storage representation should change modification information, till new indication occurring, keeping the state of this change to carry out frequency inverted.Have, frequency f n that can be illustrated to Fig. 7 (n=0～7) once changes again.
In addition, under the situation that control part 20 decision communicates by the frequency division multiplexing among receiving and transmitting part 35-1 and the receiving and transmitting part 35-2, with many mobile station apparatus 3, control part 20 can send new indication, makes it turn back to by the frequency division multiplexing among receiving and transmitting part 35-1 and the receiving and transmitting part 35-2 to communicate processing with many mobile station apparatus 3.At this moment, receiving and transmitting part 35-1 and receiving and transmitting part 35-2 can delete the above-mentioned modification information of being stored, and write new frequency in the frequency storage list.In addition, send signal deciding portion 37, from data communication section 31-1, obtain the transmission signal, and the transmission signal that should send by the 30-2 of transmission-receiving function portion according to the transmission signal deciding of this acquisition, and end this transmission signal that should send is input to processing among the data communication section 31-2.
Then, receiving and transmitting part 35-1 and receiving and transmitting part 35-2 are above-mentioned frequency after changing with the frequency translation of modulating wave, utilize the antenna that has separately to sending between radio zone.Then, the modulating wave of this transmission is by reception, demodulation in mobile station apparatus 3.At this moment base station apparatus 2 in addition by utilizing the diversity transmission of 2 groups of antennas that receiving and transmitting part 35-1 and receiving and transmitting part 35-2 have, can send the transmission signal of mobile station apparatus 3 demodulation of being more convenient for.
Like this, can effectively utilize the R-T unit in the base station apparatus 2, and can receive the electric wave that sends from a plurality of transmission-receiving function 30-n of portion by enough mobile station apparatus 3, even in the mobile station apparatus 3 from the electric wave of 1 30-n of transmission-receiving function portion owing to be subjected to a little less than the field intensity or the influence of phasing makes electric wave receive the situation variation, also can improve electric wave and receive situation by receive diversity.In addition, for the receiving intensity in the mobile station apparatus 3 is more weak, owing to pass through from 2 groups of electric waves that antenna transmission is identical, can improve the transmission intensity of electric wave on the whole, strengthen the field intensity of the electric wave that a mobile station apparatus 3 received, therefore the electric wave that also can improve like this in the mobile station apparatus 3 receives situation.In addition, carry out above-mentioned processing simultaneously, can reduce the frequency that mobile body communication system 1 uses on the whole, and can reduce the situation that the close electric wave of frequency band is interfered mutually that takes place by many stylobates station arrangement 2.
Moreover, though in the processing during above-mentioned transmission, send signal deciding portion 37,31-n is connected with data communication section, the transmission signal that the transmission signal that foundation is imported to data communication section 31-1 from control part 20, decision are imported to data communication section 31-2, but so in the 30-2 of transmission-receiving function portion, determine the Signal Processing of transmission, both can be in the stage of obtaining modulating wave, be to carry out in stage of radio control section 32-n, the stage of also can be in the stage of timing groove, promptly not having a wire casing control part 34-n carries out, also can be in stage of conversion frequency, be to carry out in stage of receiving and transmitting part 35.
As above result, frequency shown in Figure 7 is changed as shown in Figure 4.The employed frequency of groove by receiving and transmitting part 135-2 transmitting-receiving among Fig. 7 is f4～f7, but the employed frequency of groove of being received and dispatched by receiving and transmitting part 35-2 among Fig. 4 adopts the employed frequency f 0～f3 of receiving and transmitting part 35-1.Like this,, R-T unit can be effectively utilized, the influence of interference wave can be alleviated simultaneously the modulation in base station apparatus or the mobile station apparatus by in a plurality of receiving and transmitting part 35-n, adopting identical frequency.
