Description

Combined communications system, inhibit signal dispensing device, wireless base station and method
Technical field
The present invention relates to combined communications system, inhibit signal dispensing device, wireless base station and the method for the overlapping new and old a plurality of communication systems of a kind of at least a portion with band system band.
Background technology
Radio communication is used to various uses such as mobile phone, WLAN, broadcast (surface wave, satellite), radar, position location.Except that these existing systems, prediction will study from now on improved the 3-G (Generation Three mobile communication system) of in 3GPP, studying and the specification that obtains be Long Term Evolution (LTE:Long term evolution), at the Frequency Distribution of new system such as fourth-generation system.In addition, follow the rapid of in recent years mobile communication system, it is broadband to distribute desired frequency bandwidth also to trend towards.
On the other hand, radio frequency resources is limited, and according to countries and regions, the behaviour in service of frequency may not be identical.Consider these situations,, monopolistic a large amount of broadbands are assigned to All Countries and All Ranges without exception, non-easy thing for the new system in future.In addition, because transmission characteristic is different because of frequency band, according to purposes, the distribution degree of freedom of desired frequency band also is subjected to qualification to a certain degree, and the distribution of estimated frequency is difficulty more.
Therefore, in the frequency band of current use,, can realize Frequency Distribution, perhaps can realize more effective utilization of frequency new system by importing the structure that existed system is not impacted.
The existing method of non-patent literature 1 grade record is as the frequency sharing technology between the new-old system, as UWB, the use of new system is defined as the interior space, also according to existed system fixed constraints transmission power level.
The existing method of record such as non-patent literature 2 grades is as the DFS of IEEE802.11h standard specification, certain hour detection signal before sending traffic data, confirm whether existed system is using this frequency band, use the untapped frequency band of existed system to send.
Non-patent literature 1:Ultra-wideband radio technology:potential and challengesahead Porcino, D.; Hirt, W.; CommunicationsMagazine, IEEEVolume41, Issue7, July 2003 Page (s): 66-74
Non-patent literature 2:IEEE 802.11WG, Part 11:Wireless LAN Media AccessControl (MAC) and Phisical layer (PHY) specifications, Amendment5:Spectrum and Transmit Power Management Extensions in 5GHz band inEurope, Oct.2003
In the method for utilizing place and transmission power level of fixed constraints frequency band as non-patent literature 1, have only under the situation of the terminal that does not have the existed system that may be interfered around, could limit it and utilize place and transmission power level, this viewpoint from effective utilization of realization frequency considers it is not optimal way.Especially the utilizing under the situation situation different because of the region of frequency, and the lower existing communication system of frequency of utilization uses under the situation of various frequency bands, will worry that the utilizable frequency resource of new system is very restricted.
In addition,, be the situation of the receiver play at existed system and be under the situation of receiver etc. of satellite system, will be difficult to effectively avoid interference about whether having existed system to make the method that is used for avoiding interference around as non-patent literature 2, detecting.This means that the resource that can distribute to new system is very limited.Its reason is that the action of for example new system is restricted in whole play area, like that will whether irrelevant in the periphery action of each transmitter with the receiver of existed system, and the action of new system will be restricted in the more whole zone.This point is considered from the viewpoint of effective utilization of realization frequency neither optimal way.In addition, even want to detect the action of the receiver of existed system, because the receiver self of Play System does not send signal, so it is just very difficult to detect the adaptability self of receiver of Play System in new system.
Summary of the invention
Problem of the present invention is in the overlapping new and old a plurality of communication systems of at least a portion of band system band and when depositing, and realizes effective utilization of frequency.
The inhibit signal dispensing device of Shi Yonging in the present invention uses in the overlapping hybrid system of the band system band of at least a portion of the band system band of old communication system and new communication system.The inhibit signal dispensing device has: the unit that the situation that is which frequency band to the actual service band that communicates in distributing to the frequency band of described old communication system monitors; Generate the unit of the inhibit signal that the described service band of expression should not use by described new communication system; And described inhibit signal is notified to the unit of the communicator of described new communication system, this inhibit signal dispensing device is synchronously discerned identical boundary of time slot with other inhibit signal dispensing devices with identical function.

Embodiment
Fig. 1 represents the system configuration supposed in this manual.Wherein, the frequency band that uses as the satellite play system of existed system, overlap at least with the band system band of distributing to as the communication system of new system.
Owing to should preferentially use the frequency of existing distribution system, new system can not bring interference to this satellite system when work.
In the method shown in the present embodiment, be arranged near the receiver of existed system as the jamming report sender unit of " inhibit signal dispensing device ".Sending " inhibit signal " by this jamming report sender unit to new system is the jamming report signal, and request suppresses the use of partial-band to new system.On the other hand, the jamming report signal that new system monitoring sends from the jamming report sender unit only when not detecting this jamming report signal, can freely use the frequency band of distributing to new system.Wherein, the utilization of jamming report signal is the channel of the transmission preparation of this signal specially.
In addition, in Fig. 1, prepared the receiver and the jamming report sender unit of existed system respectively, but they also can be located on the same equipment, and use the same antenna, can also use different antennas.In addition, also can use a plurality of antennas with identical directive property.
Fig. 2 represents the format sample of jamming report signal.Preamble is the signal mode of regulation, is used for jamming report signal detecting part detection signal and estimation channel at new system base-station.Restriction uses the request frequency band to represent the corresponding ID of frequency band that uses with the request restriction.
And absolute transmission level that the jamming report signal also can comprise jamming report sender unit ID, need the improvement amount, can allow etc.In addition, though do not illustrate, also can use additional error detection bit respectively such as request frequency band and jamming report sender unit ID, perhaps to the whole additional error detection bit of several information projects to restriction.Equally, can also carry out error correction coding with certain suitable information unit.
Fig. 3 represents the structure of jamming report sender unit 30.The frequency band that this jamming report sender unit request restriction of setting recording portion 31 storages is used etc.Based on these information, jamming report signal generating unit 32 generates the jamming report signal.The jamming report signal is modulated to predetermined frequency by wireless circuit unit 33 and sends.
The base station of new system is according to top described reception jamming report signal, and moves according to these information.And, in order to grasp whole disturbance regimes, the channel that does not use existed system using in the base station.The channel that existed system is using is considered to be called " service band " from the angle of existed system, considers also can be called " restriction service band " from the angle of new system.By forbidding that up channel is distributed this service band, will no longer be necessary in the terminal setting of system and the test section of jamming report signal correction and the action of carrying out corresponding to testing result newly.And, the specification that the specification of new system need can be moved for the whole frequency bands that do not use the service band that is designated as existed system.According to this viewpoint, use the OFDM modulation system more favourable.This is because by using the OFDM modulation system, can easily and change the frequency of use neatly.In the explanation afterwards, suitable OFDM modulation system as prerequisite.
[embodiment 1]
Fig. 4 represents the topology example of the base station of new system.The signal that the wireless circuit unit of being recorded and narrated by right side among the figure receives is separated into the signal that might comprise the jamming report signal and the signal of new system.And, might comprise that the signal of jamming report signal is transfused to the jamming report signal detecting part.
When the jamming report signal detecting part comprises the jamming report signal in received signal,, result of determination is notified to resource allocation section according to this jamming report signal determining restriction service band.As mentioned above, said restriction service band refers to the frequency band that existed system uses in practical communication.
Resource allocation section is used the frequency band beyond the frequency band that is set to the restriction service band, carries out the resource allocation of up channel and down channel.In the frequency band of the actual use of existed system, the base station of the system that look for novelty not only can not send normal data-signal, and can not send all signals such as preamble, pilot signal.In addition, resource allocation section is carried out the planning of Radio Resource, so be also referred to as planner.And pilot signal can be other known any appropriate signal before communication such as reference symbol (RS), training program, known signal.
The data-signal generating unit is according to the transmission data of being imported with from the information of resource allocation section etc., generates to send signal and also export to multiplexing unit.
The control signal generating unit is according to system parameters with from the information of resource allocation section, and the control signal that generation will send is also exported to multiplexing unit.
Multiplexing unit is for data-signal of being imported and control signal, according to the next multiplexing signal of the resource allocation information of same input.And, carry out the multiplexing of pilot signal.
These signals are transfused to the OFDM modulation portion, the time signal that generation will send.This time signal is transfused to wireless circuit unit, carries out modulation and filtering, power amplification etc. to transmission frequency, and sends the signal that is as a result of generated.
Fig. 5 represents the topology example of jamming report signal detecting part.The preamble test section judges in the signal that is received whether comprise preamble.At this, when not reaching set incoming level as the signal that preamble received, do not carry out the action of back.When detecting preamble, the action of beginning aft section.
At first, channel estimation unit is carried out the estimation of channel.And balanced portion uses the equilibrium treatment of being carried out received signal by channel estimation unit estimated channel estimated value.Mapping portion is separated in the received signal input that is implemented after the equilibrium treatment, detects from receiving symbol and receives bit.The reception bit sequence that is detected is implemented error correction decoding in the fec decoder portion of back, and decoded result is transfused to CRC portion.In CRC portion, whether contain wrong in the burst that detection is imported.There is faultless situation to be transfused to restriction service band detection unit.
Also can in the transmitter information storage part, set transmitted power, frequency band external radiation amount from transmitter, and import-restriction service band detection unit, needed guard band width calculated according to these values.
In restriction service band detection unit, the frequency band that utilizes the jamming report signal to be notified is set to the restriction service band.Wherein, although received the jamming report signal,, also can limit the use of whole frequency bands (for example the wrong result of determination of CRC is under the situation of NG) under the situation that can not correctly receive.

[embodiment 2]
<CSMA>
The geographical density of Fig. 7 (a) expression jamming report sender unit is easy to generate the state of jamming report signal conflict when big.In illustrated example, signal B conflicts with signal C.About this problem, also can use the technology of avoiding interference that in the past proposed is the method that CSMA/CA and time slotization send.
When using the method for CSMA benchmark, before the signal that sends as the traffic data, monitor ambient state, whether sending the jamming report signal around confirming.When on every side at transmission jamming report signal, make transmission put off until next send opportunity (Fig. 7 (b)) from the jamming report signal of standing certainly.On the other hand, when not sending the jamming report signal on every side, carry out from the transmission of the jamming report signal at station certainly.
＜time slotization 〉
Time slotization is that the jamming report sender unit can begin the transmission of jamming report signal regularly unified alignment, and receiver side can use signal separation techniques received signal to be separated into simultaneously the method for each signal.In order carry out time slotization, need between the jamming report sender unit, obtain synchronously.This for example can use GPS to obtain synchronously.By carry out time slotization, can avoid being difficult to carry out the local conflicts of Signal Separation, can reduce the probability that takes defeat because of conflict.And, think owing to determining to a certain extent to receive regularly, so also have the effect of carrying out the reception of new system base-station easily.
In addition, after once sending successfully, in order regularly to carry out the transmission of jamming report signal with both fixed cycles, also can be considered as being preengage in the transmission of this timing, other jamming report sender units regularly begin to disturb the transmission of report signal at other.
And, in the manner,,, guarantee synchronously so also can regularly send according to the transmission of jamming report sender unit on every side as long as the part obtains synchronously.And, under the situation of local synchronization, there is the jamming report sender unit around needing at least, but in the situation that does not have a plurality of this devices, and the situation of the jamming report signal around not receiving in the hypothesis certain hour in the past is inferior, and each terminal can be at any timed sending signal.
＜synchronously+CSMA 〉
In addition, also can and use CSMA and time slotization.But, according to around the transmission situation of jamming report signal obtaining under the situation of local synchronization, need according to the methods below 1 or method 2 shown in adjust the jamming report signal transmission regularly.This is because when carrying out time slot, needs unifiedly as the time that sends benchmark regularly, then needs to realize the randomization that compensates in CSMA.
(method 1)
As shown in Figure 8, for the length sum that makes postamble and compensation is certain, in the additional postamble in the back of jamming report signal.The transmission concluding time of postamble as benchmark regularly, determine to send beginning regularly.
(method 2)
As shown in Figure 9, the transmission of preamble signal regularly as benchmark, was sent the signal that is used to report the transmission beginning before preamble.In addition, regularly sum is certain with compensation to keep this to be used to report the signal that sends beginning.
In above-mentioned two examples, frame 2 begins earlier to send, so frame 2 obtains transmission route, after frame 2 sent, frame 1 sent in next chance.
Under according to the top described situation of obtaining local synchronization, might mix the situation that the jamming report signal received synchronously and the situation of asynchronous reception of existing.
In this case, new system base-station also can be prepared synchronous receiving mode and asynchronous receiving mode, and according to following described action.
The base station is under synchronous receiving mode, and the timing that utilizes local to calculate determines that next frame begins regularly, and after the reception of arrival frame began regularly, the reception that begins frame recited above was handled.At this moment, also can detect the correction of the timing of correction of timing local calculating according to preamble.In addition, after detecting whole signals, generate the duplicate of the signal that is received, confirm the power behind this duplicate of deletion from received signal in specific timing.As long as can guarantee that synchronously, then the power after the deletion is extremely small, otherwise, with residual sizable power.Therefore, as long as this power more than set value, then changes asynchronous receiving mode over to.
Under asynchronous receiving mode, make correlator action all the time at each spreading code, monitor relevant output.Under asynchronous receiving mode, during more than the certain hour, only after set timing receives the jamming report signal, change synchronous receiving mode over to.At this moment, determined synchronization timing is not limited to one, also can be more than two.
[embodiment 3]
The jamming report signal will limit the use of new system base-station to Radio Resource, so consider from the viewpoint of effective utilization of realizing frequency, not wish to send the above jamming report signal of necessary degree.In addition,, also will cause the increase of collision probability between the power dissipation of jamming report sender unit of existed system and the jamming report signal, so say from this point neither optimal way even in existed system.
In the 3rd embodiment of the present invention, the jamming report sender unit only under the situation of the existed system receiver action of correspondence, carries out the transmission of jamming report signal, if not action then do not send the jamming report signal.Therefore, the jamming report sender unit need possess the function of judging whether the existed system receiver moves.This function can utilize following method to realize.
One of implementation method is according to offering the quantity of power (Figure 10) of the antenna of existed system receiver or offer the quantity of power (Figure 11) of tuner, judges whether energized of receiver.
When mensuration offered the quantity of power of tuner, the amount of power consumption of these equipment in course of action may not be certain, so the median of the minimum value of the lowest power of the maximum that the threshold value of quantity of power should be set at standby power when using.This threshold value can manually be differentiated also and can dynamically judge.And, be not limited to instantaneous performance number in the value that is used to judge, also can be temporal mean value.In addition, when the power connection of tuner, also can not be confirmed to be the judgement that does not disconnect often, but during certain, confirm.
, when existed system was Play System, general a plurality of playback channels are parallel simultaneously to be sent, and the existed system receiver receives one of them (according to circumstances being more than two sometimes).These playback channels send in the frequency division multiplexing mode according to frequency band A, B, C etc. respectively.
Said method based on the operating state (ON/OFF) of the receiver of existed system, for the existed system receiver of making for giving no thought to jamming report of the present invention, say more favourable from this point that the jamming report sender unit can be installed easily.But owing to only considered the ON/OFF of existed system receiver, whole frequency bands that will cause using in the existed system receiver can not use (Figure 12) in new system.
Be conceived to the difference of the frequency band of playback channels,, in new system, only limit each frequency band that the existed system receiver is receiving, can further improve the service efficiency (Figure 13) of frequency thus at each time point.In Figure 13, a service band B in fact, frequency band A, C are identified as in existed system and also do not use.
Under the situation of the frequency band (the frequency band B of Figure 13) that restriction is only receiving corresponding to the existed system receiver of jamming report sender unit, described the action of jamming report sender unit is got final product according to following.Promptly, when the existed system receiver moves, the current frequency band that is receiving can be notified to the jamming report sender unit, perhaps bring into use and switch under the situation of playback channels the user, also the playback channels of switching object can be notified to the interference signal annunciator, the interference signal annunciator is determined the current frequency band that is using.And, send the jamming report signal, so that only limit the use of this frequency band.
And, when carrying out the reception of two playback channels at the same time, ban use of frequency band to get final product corresponding to current two playback channels that receiving.
And, be not limited to Play System, in communication system, generally prepare a plurality of frequency bands, terminal uses one of them frequency band to communicate, so also can be suitable for said method.
[embodiment 4]
The 4th embodiment of the present invention realizes the efficient activity of the report of interference signal.Figure 14 represents the schematic block diagram of the jamming report signalling 140 that embodiments of the present invention relate to.The frequency band that the 141 storage request restrictions of setting recording portion are used etc., and connect jamming report signal generating unit 142.Wireless circuit unit 143 connects antenna, interference signal acceptance division 145 and jamming report signal generating unit 142.Wireless circuit unit 143 is amplified the wireless signal that receives from antenna, sends to interference signal acceptance division 145.Interference signal acceptance division 145 amplifies the signal of the frequency band that should monitor in the signal that is received, and sends to send control part 144.Jamming report signal generating unit 142 generates the transmission signal of jamming report signal according to from the information that sends control part 144 and setting recording portion 141, sends to wireless circuit unit 143.Wireless circuit unit 143 will send frequency and the transmission that the signal modulation becomes regulation.
In addition, in the jamming report sender unit, only under the situation that receives interference signal, send the jamming report signal.At this, in the judgement that receives interference signal, not only measure the current frequency band that is using of existed system receiver about whether, also undertaken by the interference signal received power in the frequency band of measuring new entire system.
As shown in figure 15, the jamming report sender unit only monitors the frequency band B that the existed system receiver is receiving.During this situation, can consider following situation:
1. the jamming report signal sends and is notified to new system base-station.
2. new system base-station stops to utilize the frequency band (restriction service band B) according to the appointment of jamming report signal to send.
3. in restriction service band A, no longer receive interference signal.As a result, the jamming report sender unit stops to send the jamming report signal.
4. new system base-station does not receive the jamming report signal that bans use of restriction service band B, so use restriction service band A to begin once more to send.
5. the jamming report sender unit detects to produce in restriction service band B and disturbs, and sends the jamming report signal to new system base-station once more.
Because the non-efficiency of jamming report signal sends, worry will cause the existed system receiver regularly to be interfered in restriction service band A like this.
The 4th embodiment is used to tackle this problem.The current frequency band that is receiving of existed system receiver not only, the received signal of frequency band in addition also is contained in the monitored object.Thus, can judge whether existed system exists the transmitter-receiver (whether communicating) of new system on every side.When having the transmitter-receiver of new system, even being currently used in the frequency band of reception, the existed system receiver do not have interference signal, also regularly send the jamming report signal that request bans use of this frequency band to new system base-station, can tackle above-mentioned worry thus.
In addition, the jamming report sender unit can be discerned interference level, can determine the transmission output of jamming report signal and the spread spectrum rate of jamming report signal etc. adaptively thus.For example, use set level or spread spectrum rate when sending in the early stage, but when the interference signal level that is received drops to enable level, can increase transmitted power and send, perhaps also can increase the spread spectrum rate and send.
And the mensuration of interference level can be undertaken by the jamming report sender unit, perhaps also can be carried out the mensuration of interference level by the existed system receiver, and be notified to the jamming report sender unit.
In addition, when the portable terminal of the new system that the scope that belongs to outside the coverage area of jamming report signal moves restarted to send, worry might be interfered.
This problem can solve during the interim transmission by explanation among the embodiment 7 that portable terminal is given in the back.The portable terminal of wanting to carry out the signal transmission carries out the transmission of signal in advance during this interim transmission.The transmission of the signal during this interim transmission can be carried out in the untapped frequency band of existed system receiver, also can preestablish the obsolete time of existed system receiver in the frequency band that the existed system receiver uses, and send in this time period.During interim the transmission, each existed system receiver observation signal according to whether carrying out the transmission of signal during this interim transmission, determines whether to carry out the transmission of jamming report signal.

Can there be one in the jamming report sender unit, also can have many.The 5th embodiment of the present invention relates to when having many jamming report sender units, the jamming report signal is notified to expeditiously the technology of new system.For example, suppose to exist two jamming report sender unit A, B and a new system base-station C.Suppose that the jamming report signal of being prepared by jamming report sender unit A, B is identical temporarily, if these jamming report signals are notified to new system base-station respectively independently, then efficient is low.Therefore, for example the jamming report signal that sends from jamming report sender unit A is received by jamming report sender unit B, under the situation of its expression identical frequency band when being reported by jamming report sender unit B, jamming report sender unit B also can not send the jamming report signal.But in this mode, perhaps the position relation according to jamming report sender unit and new system base-station can produce the interference that can not ignore in existed system.
As shown in figure 16, suppose to exist two jamming report sender units and a new system base-station.New system base-station can not receive the jamming report signal that sends from jamming report sender unit A, but can receive the jamming report signal that sends from jamming report sender unit B.As above-mentioned action, from the jamming report signal indication of the jamming report sender unit B frequency band X identical with the signal that will be reported by jamming report sender unit B the time, jamming report sender unit B does not send the jamming report signal.During this situation, perhaps new system base-station C does not receive the jamming report signal, and service band X carries out certain communication.As a result, worry in frequency band X, to produce the interference of the system of making a fresh start.
The 5th embodiment of the present invention is used to tackle this problem.Jamming report sender unit B confirms from the incoming level of the jamming report signal of jamming report sender unit A reception.When this incoming level was big, jamming report sender unit B did not send the jamming report signal.At this incoming level hour, jamming report sender unit B sends the jamming report signal.The magnitude relationship of incoming level can be by comparing to determine with predetermined threshold value.According to magnitude relationship from the incoming level of the jamming report signal of other devices, determine whether to send the jamming report signal from device certainly, can tackle the problems referred to above effectively thus.When nearer to a certain extent, jamming report sender unit B suppresses the transmission of jamming report signal at the interval of jamming report sender unit A, B.Only when this is quite far away at interval, send the jamming report signal from jamming report sender unit B.
In addition, jamming report sender unit B can consider that also the incoming level of interference signal determines whether to send the jamming report signal.For example, when the incoming level of the jamming report signal that receives from other devices A hangs down, if it is higher to install the interference level of B certainly, then send the jamming report signal, otherwise do not send the jamming report signal.For example, under situation shown in Figure 16, jamming report sender unit B and new system base-station C distance is big and the interference level of the system of making a fresh start hour, jamming report sender unit B does not send the jamming report signal.Like this, can be only according to actual needs degree control the restriction of the frequency band that new system is used, on the other hand, also the transmission of jamming report signal can be defined as only and when actual needs, carry out.
In addition, as shown in figure 17, about the use of not shown restriction service band X (frequency band X), because jamming report sender unit A has sent jamming report signal Y, so jamming report sender unit B suppresses the transmission of jamming report signal, can consider following situation to this situation.Under the situation that the transmission from the jamming report signal Y of jamming report sender unit A has stopped, in order to make existed system continue service band X, the jamming report sender unit B that suppresses the transmission of jamming report signal must begin to disturb the transmission of report signal.Before this, might cause new system base-station C to begin to send.That is, as shown in figure 18, before jamming report sender unit B sends the jamming report signal, send signal, result, the interference of worrying in frequency band X, to produce the system base-station C that makes a fresh start from new system base-station C.
In order to tackle this problem, as shown in figure 19, jamming report sender unit B monitors the jamming report signal Y that sends from adjacent jamming report sender unit A all the time, and after new system base-station C can stop in the reception of jamming report signal Y, change the action of proceed-to-send signal after wait specified time limit (" sending the stand-by period " among Figure 19) over to.Like this, jamming report sender unit B can send the jamming report signal before new system base-station C proceed-to-send signal, can be in frequency band X be subjected to the making a fresh start interference of system base-station C, and existed system can continue to receive desired signal.
[embodiment 6]
In above-mentioned each embodiment, the jamming report sender units different with new system base-station generate and send the jamming report signal.But, the invention is not restricted to this mode, for example new system base-station can be judged in person could service band, generates and sends the jamming report signal.By making new system base-station have this function, when the geographic configuration density of jamming report sender unit and work ratio are big, can reduce jamming report number of signals (reducing conflict), realize the effective utilization of existed system and new system to frequency.
At first, suppose mix to exist the jamming report sender unit (for example A among Figure 16, B) that illustrated in the above-described embodiments and the new system base-station of present embodiment.The base station of present embodiment is reported the frequency band that suppresses to use (limiting service band X) according to the situation of current jamming report with the information of setting in advance in the zone of this base station as the restricted band report signal.New system uses the frequency band except that restriction service band X.When the jamming report sender unit was contained in this restriction service band at the frequency band X of the actual use of existed system, the request of not sending banned use of the jamming report signal of frequency band X.This is because the restricted band report signal notice of the system base-station that has been used to make a fresh start finishes.On the other hand, when only the frequency band that uses at existed system was not contained in this restriction service band, the jamming report sender unit just sent the jamming report signal.
In the present embodiment, the jamming report sender unit is according to following described action.
1. judge whether to send over from the base station jamming report signal (whether being the restricted band Report mode), this signal is used to ask the frequency band X that bans use of existed system reality using.Whether the differentiation basis of pattern has received the restricted band report signal from new system base-station is judged.
2. when the pattern in the base station is not the restricted band Report mode, carry out the action that has illustrated in the above-described embodiments, carry out the transmission of jamming report signal.
3. when the pattern in the base station was the restricted band Report mode, the jamming report sender unit was analyzed the restricted band report signal of the system base-station of making a fresh start, and determined to suppress the frequency band that new system uses.Judge whether this frequency band is the frequency band of forbidding corresponding to the request of jamming report sender unit.If not corresponding, then the jamming report sender unit is carried out the action that has illustrated, and sends the jamming report signal.If corresponding, then the jamming report sender unit does not carry out the transmission of jamming report signal.
Figure 20 represents the apparatus structure example of the jamming report sender unit that uses in the present embodiment.
Restricted band report signal acceptance division receives the restricted band report signal that sends from new system base-station, confirms to have or not restricted band report signal and content thereof, result notification is given send control part.
The restricted band report signal can be reported by dedicated frequency band, also can send by the frequency band identical with the jamming report signal.
Send control part according to from the information of restricted band report signal acceptance division input with from the information of setting storage part, judge the transmission necessity of jamming report signal, the action of control jamming report signal generating unit.
In the present embodiment, the base station (or terminal) of new system also needs to carry out following action except that above-mentioned action.
1. judge the necessity that changes the restricted band Report mode over to.
2. stop the distribution of restricted band.
3. base station and/or jamming report sender unit around band-limited signal (jamming report signal) being notified to.
4. the handover event of confirming pattern (is for example judged the end of restricted band Report mode.)。
About when beginning the judgement of restricted band Report mode,, can determine according to following determinating reference as an example.
Manually determine the timing and the frequency of beginning restricted band Report mode in advance.
Determine according to the transmission situation of the jamming report signal that is detected (source quantity, send during etc.).
Determine according to the jamming report signals from collision frequency that is detected.
System loading according to new system is determined.
About when finishing the judgement of restricted band Report mode, for example can behind the certain hour after the restricted band Report mode begins, remove.But, in the method, might cause the restricted band Report mode is set at the unnecessary long period, on the contrary more in short-term, might cause the beginning of restricted band Report mode and the execution frequency of process ends to increase.This is because under the restricted band Report mode, sends the jamming report signal of relevant this frequency band from the jamming report sender unit, so can not suitably judge the working condition of existed system, the suitably timing of judgment model switching.
Considering from the viewpoint of tackling this worry, is under the situation of restricted band Report mode at new system base-station, also can send the jamming report signal at certain intervals from the jamming report sender unit.The certain intervals of this moment should be set at longer than the interval that sends common jamming report signal.This certain intervals need consider to be used for to determine that the lift restrictions interval of timing of frequency band Report mode, base station sets.In addition, about certain intervals, also can be at the signal of the transmission of other jamming report sender units A around jamming report sender unit B, when request bans use of the identical frequency band of the frequency band with the actual use of jamming report sender unit B, behind the certain hour of the transmitting time of this signal, sending from jamming report sender unit B.About the judgement of jamming report sender unit on every side, can use method recited above to judge.And above-mentioned certain intervals also can be notified by the base station.During this situation, the jamming report sender unit also needs to receive the function of this report signal except that the function of the content of analyzing the restricted band report signal.
And the jamming report sender unit is not limited to send at certain intervals the jamming report signal under the restricted band Report mode, also can send aperiodically or as required.For example, new system base-station sends the signal of " urging the jamming report signal of relevant restricted band ", and each jamming report sender unit can send the jamming report signal according to this signal.At this moment, in the jamming report sender unit,, can confirm according to the received signal level of the frequency band beyond the top described restricted band by inquiry for the working condition of the terminal of the new system around judging.
The transmission of restricted band report signal can be undertaken by the device beyond the base station, but is preferably undertaken by new system base-station.
In addition, in embodiment 7, as shown in figure 21, worry to send signal, and be interfered from the new system base-station C new system base-station D in addition that has sent the restricted band report signal.That is, as shown in figure 22, during new system base-station C transmission restricted band report signal, also might send signal from new system base-station D.
In order to tackle this worry, following method is arranged.That is, as shown in figure 23, get final product during setting certain interim transmission.Want to carry out the new system base-station D that signal sends, during this interim transmission, carry out the transmission of signal in advance.Send about the signal during this interim transmission, can in the untapped frequency band of existed system receiver, carry out, also can in the frequency band that the existed system receiver uses, preestablish the obsolete time of existed system receiver, and send in this time period.During interim the transmission, each existed system receiver observation signal according to whether carrying out the transmission of signal during this interim transmission, determines whether to carry out the transmission of jamming report signal.Like this, during interim the transmission after, the signal of the system base-station D that can suppress to make a fresh start sends, and can avoid interference.
[embodiment 7]
When certain jamming report sender unit sends the jamming report signal, if other jamming report sender units on every side send the jamming report signal, signal will conflict.This conflict also produces between restricted band report signal that sends from new system and jamming report signal.Below, be that example describes with the conflict between the jamming report signal.When wanting to detect the jamming report signal, might be able to not correctly detect.Reduction jamming report signals from collision probability method more than has been described.The 7th embodiment of the present invention also can improve the probability of correct reception jamming report signal behind the jamming report signal conflict.Therefore, the jamming report signal is sent by spread spectrum.As an example of the spreading code that uses, can carry out following selection herein.
Select at random.
The spreading code that is using around detecting uses obsolete sign indicating number.
Detect the spreading code that is using on every side, consider that the frequency band Y that bans use of comes option code (concrete condition is as described below) around the request of device limits the frequency band X that uses and asks.
In addition, as mentioned above, send timing by generalization, after once sending successfully, under the situation that sends same signal at certain intervals, also can be according to following described selection spreading code.
Figure 24 is illustrated in the jamming report sender unit 240 that uses among the 7th embodiment of the present invention.Jamming report sender unit 240 detects the spreading code that uses around installing certainly, determine the spreading code that will use.In the present embodiment, on the architecture basics of the jamming report sender unit 30 that has illustrated, also need spread spectrum portion 245 and spreading code selection portion 242, report signal acceptance division 243.
Wireless circuit unit 246 connects antenna, spread spectrum portion 245 and report signal acceptance division 243.Wireless circuit unit 246 is amplified the wireless signal that receives from antenna, sends to report signal acceptance division 243.Report signal acceptance division 243 is according to the report signal that is received, the spreading code that is using around detecting, and the frequency band that uses in these signals of detection limit.
The frequency band that 241 storage jamming report sender units, the 240 request restrictions of setting recording portion are used etc.In addition, setting recording portion 241 connects spreading code selection portion 242 and jamming report signal generating unit 244.
Spreading code selection portion 242 is according to the restricted band of the spreading code that is detected, the request restricted band that is detected and 241 requests of setting recording portion, according to the spread-spectrum signal of the method selection of narrating later by 240 uses of jamming report sender unit.
Spread spectrum portion 245 uses the spreading code of being selected by spreading code selection portion 242, will be from the transmission signal spread-spectrum of jamming report signal generating unit 244 inputs, and export to wireless circuit unit 246.Wireless circuit unit 246 will send frequency and the transmission that signal is modulated to regulation.
About the selection of sign indicating number with send regularly, under the jamming report signal that is sending the around situation identical, selects identical spreading code with the frequency band that limits at new system base-station, make the jamming report signal and the timing synchronized transmission that send around.Under this situation, about the field that sender ID etc. sets respectively, also can dual spread spectrum.And, in this case, when operable spreading code has when restriction and surpasses the spreading code quantity of specified quantity, can use set common ID and set spreading code.
On the other hand, when the jamming report request signal that sending is around used at the different frequency band of new system base-station, select different spreading codes.In addition, also can seek the minimum timing of amount that prediction sends the jamming report signal, at this timed sending jamming report signal.
According to the operating position of spreading code on every side, when selecting the spreading code that will use, using new same spread sign indicating number or the short of notice failure that is judged as the jamming report signal, just can use identical spreading code around short of the detecting.About the transmission of jamming report signal failure (can not suitably receive), for example can wait and estimate according to after sending the jamming report signal, still receiving many interference signal amounts at receiver side.
And, about the spread spectrum rate, can set set value, also can determine adaptively.For example, use the value of regulation when sending in the early stage, but when the interference level that receives surpasses enable level, increase the spread spectrum rate, perhaps when interference level descends, reduce the spread spectrum rate.
[embodiment 8]
The method of the conflict that avoids interference report signal more than has been described.But the conflict that avoids interference fully in the reality is very difficult.That is, in the jamming report signal detector of reality, promptly allow to detect the existence of jamming report signal, also can not normally detect the content of jamming report signal.For example, can utilize error-detecting code subsidiary in the jamming report signal to judge the success or not of reception.As a example, at set certain hour proceed-to-send signal not at the countermeasure of this situation.Wherein, about set certain hour, for example under the fixed situation in interval that sends the jamming report signal, also can be set at this interval.
And, problem reason about the content that can not normally receive the jamming report signal, may not be confined to the jamming report signals from collision, also exist the incoming level (quality of reception) of jamming report signal very low, cause the situation of the decision error of signal owing to The noise.In this case, think that new system base-station and existed system receiver distance is quite far away.Therefore, in this case, when detecting the jamming report signal, under it fails normal situation about receiving, if the incoming level of jamming report signal below setting, then not response band ban use of request.
[embodiment 9]
, after the jamming report sender unit sent the jamming report signal, estimation condition can not improved (thoroughly) yet.Under the communication environment of reality, because the problem of relation such as the position of the transmission situation of electric wave, base station etc., equipment, the improper application of new system base-station etc., although sent the jamming report signal, perhaps the interference signal amount that existed system receives does not have (fully) to reduce.
As the corresponding scheme of this situation, can make jamming report system doublingization (A of jamming report system, B), utilizing the A of jamming report system can not thoroughly improve under the situation of situation, use the jamming report B of system to realize the improvement of situation.
Under the situation that makes the jamming report system doublingization, the content that the content of side's jamming report A of system request and the opposing party's jamming report B of system ask can be different.
For example, after the A of jamming report system notified, the new system base-station that receives notice from the B of jamming report system stopped the distribution of frequency band at once, and carries out the analysis of causes.
Perhaps, also can carry out following processing.
Can start the jamming report signal detecting part (or whole R-T unit) of the A of jamming report system once more.
Can notify attendant or operator.
Can determine ID, and notify this ID simultaneously as the new system base-station of the reason (interference source) that causes interference.
In addition, when the reason that can not improve at interference level is up link, also can determine user's set (mobile radio station is typically arranged, but also can be fixed station) as reason.Can also grasp the higher user's set of the frequency become the problem reason of disturbing between the system in application side, for this user's set, new system applies person implements to carry out suitable processing such as the test of respective user devices or exchange.
About determining as the link (up, descending) of cause of failures and user's set, preferred interference detecting apparatus is except that detecting interference signal, also carry out the analysis of the control signal of new system, wait and determine by grasp frame number, the classification of upstream and downstream, terminal recognition sequence number.
About the interference that disturbed reporting system B detects, also can notify this station or the mechanism of the rational Application that realizes frequency.In addition, the interference notice that the B of jamming report system carries out is not limited to the electric wave notice, also can utilize the circuit of other common wireless communication systems, can also utilize wired telephone communication network, the Internet wire.
More than, with reference to certain embodiments the present invention has been described, but each embodiment simple example only, those skilled in the art are appreciated that its various modified example, modified example, alternative exemplary, displacement example etc.For example, in making the system that sends the jamming report signal Synchronization, should make other jamming report signals and send regularly synchronous terminal and also can move asynchronously.Should carry out under the situation of jamming report according to the work of existed system receiver, also can carry out all the time continuing to send the abnormality detection of jamming report signal, and the countermeasure when implementing abnormality detection.In addition, be not limited to abnormal operation, also can monitor terminal that sends electric wave wrongly etc.
In the above-described embodiments, be that example is illustrated with the terminal that receives play signal, but in hospital etc. owing to the influence of electronic equipment is wanted limit under the situation of communication of use characteristic frequency, also can be suitable for the present invention.In this manual, show the example that new system is a communication system, but new system also can be a Play System.About the jamming report sender unit, also can make control part etc. receive program and upgrade receiving algorithm (being suitable for so-called SDR), so that the change of the new system of defence shared frequency, specification change, system variation by wireless or Wireline.
In order to help to understand the present invention, use concrete numerical example to be illustrated, but short of special qualification, then these numerical value also can use any suitable value nothing but a simple example.The differentiation of each embodiment is not essential place of the present invention, can use plural embodiment as required yet.For convenience of explanation, the function of use block diagram illustrating devices that relate to of embodiments of the invention, but this device also can utilize hardware, software or their combination to realize.The invention is not restricted to the foregoing description, only otherwise break away from spirit of the present invention, its various examples, modified example, alternative exemplary, displacement example etc. all are contained among the present invention.
