Invention field
The present invention relates generally to communication system and subsystem thereof, especially at radio frequency (RF) communication spectrum using method, its clear channel assessment of utilizing disclosed spectral reuse transceiver in the application of above-indicated ' No. 753 and frequency hopping function come effectively to become total bandwidth for being used to hold the application in relative broadband, such as, but not limited to the transmission of data and/or video (for example voice) RF channel aggregation of the relative arrowband of a plurality of disconnections.
Background of invention
Having obtained Federal Communications Committee (FCC) such as, but not limited to several (mainly) RF spectrum users of public service entity (for example police service, fire-fighting, and utility service tissue) etc. issues use one or more is intended to support the permission of radio channel of the relative arrowband of analog voice services (such as with by promptly saying radio communication) at first.Typical spectral distribution at these narrow band channels---in the indefiniteness spectrum distribution such as graphic extension in the disconnection channel band 11 of Fig. 1, be assigned to the given channel that obtains the permission person and comprised a plurality of different bandwidth as time passes probably, plant such as in the fragment of 50KHz, 25KHz, 12.5KHz and 6.25KHz one or more, it is inevitable does not expect yet and adjoins on frequency spectrum each other.
That is, shown in spectral gaps 13, main users will be allowed, and will typically to be licensed other (main/licensed) users' of giving one or more other channels or bandwidth (breach 13) institute separated from one another for spendable all channels.The frequency spectrum inconsistency of licensed interchannel is to be in response to the increment request for allocation and to be given this fact of various users by permission sequentially because of them on the one hand, and is owing to being required to satisfying the bandwidth demand that continues to increase to stricter direction evolution by the spectrum efficiency of FCC promulgation.
What these obtained permission person's first concern is the efficient utilization that it is obtained the bandwidth of distribution.With in by the situation of promptly saying analog voice services, what suitable big figure was arranged obtains the current employing fixed frequency of permission person or the manual radio of channelizing for example.Although these radio are relatively inexpensive, they use dedicated frequency or the right occasion of frequency provide to radio channel owe utilize; If radio only is used in 10% time, then 90% of available bandwidth just be wasted.Above with by promptly saying in the analog voice services example, by adopting ' listem-before-talk ' user discipline, total the various channels that obtain allocated segments of bandwidth that just have more radio energy to share.Though this can improve spectrum efficiency, it has some users of requirement to wait for to become until frequency and empties or want the manual adjustment frequency---if this radio has this ability---and shortcoming of trial once more.
Trunked radio provides the improvement better than the design of these separate radio, because it can signaling transponder station, and the latter selects clear channel for the caller immediately.Although several adoptable cluster protocol are arranged, they total all also for other with by the mechanism of promptly saying common shortcoming---wireless channelizing can not change, and the frequency band service efficiency may be very low.
Radio described above and other similar radio are inflexible, because it can only be used for the channel (such as 12.5KHz, 25KHz or 50KHz channel) of single relative arrowband, and communication session the duration must remain on this channel---this has hindered the efficient utilization that the user is obtained the bandwidth of distribution.Moreover, as the equipment of relative narrow bandwidth, these radio can not provide the service of relative high bandwidth, such as Ethernet and Internet protocol (IP) digital service.
As a result, benefit from broadband service in order to make himself, this type of wireless user will buy cellular radio cards usually, and they can insert these cards in its personal computer and be inserted the cellular network of support (IP) digital communication by this.The open defect of this way comprises the extra charge of honeycomb card and service subscription and must depend on when taking place such as natural calamity emergencies such as (for example hurricanes)---before this, and communicating by letter between the emergency service tissue be vital---afterwards may transship or inoperative at all (honeycomb) network.
Summary of the invention
According to the present invention, the radio of the relative narrow bandwidth of these and other routines can not utilize more efficiently licensed bandwidth of giving its user (disconnection spectral channel) multi sub-carrier frequency hopping (MSFH) function of this problem of integral body by utilizing disclosed spectral reuse transceiver in No. 753 application of above-indicated ' with effectively with channel ' gathering ' one-tenth of this type of disconnection than any licensed channel wide the total bandwidth of Duoing and successfully being overcome, so make this radio can be used to broadband application, such as the transmission of data and/or video.
Particularly, utilized ' clear channel of the spectral reuse transceiver of No. 753 applications detects and the frequency agility function determine (the licensed user of giving perhaps can give agreed shared its be allowed can one or more other users of channel allocation) in the main channel of a plurality of disconnections which (for example be not used, it is wireless with by promptly saying button to have discharged it), and do not use detection based on this, effectively the channel ' gathering ' of these a plurality of disconnections is become the whole overall of potential available bandwidth, the relative high bandwidth of the regulation that the single channel wireless electricity that its frequency spectrum latitude of emulsion is enough to reach conventional at least otherwise can't satisfy requires (such as, but not limited to the transmission of data and/or video).
Typically, only require and assemble the high bandwidth requirement that this a large amount of relatively frequency hopping narrowband subcarriers that bandwidth can be subdivided into or the fraction in the subchannel or subclass just will satisfy given application (such as the transmission of numerical data).The frequency agility ability of spectral reuse transceiver of ' No. 753 applications is used between the subcarrier of different separately subsets of sub-channels or subchannel optionally frequency hopping, and wherein these subsets of sub-channels are to assemble to pseudorandom between all available subchannels that have been subdivided into from aggregate band.

Describe in detail
Before the details of describing disjoint radio channel aggregation methodology of the present invention, should observe the present invention relates in essence and makes disclosed spectral reuse transceiver in the application of cited above ' No. 753 can carry out additional function---promptly effectively (for example voice) RF channel aggregation of the relative arrowband of a plurality of disconnections is become the whole overall of potential available bandwidth, its than any individuality be allowed can narrow band channel much wide, and can hold the application in relative broadband, such as, but not limited to the transmission of data and/or video.
As will be described, by being set simply, the operation of controlling this transceiver by the employed configuration parameter of communication controler of disclosed transceiver in ' No. 753 applications just can realize this additional function.The framework of the transceiver of ' No. 753 applications remains unchanged.As a result of, the present invention is illustrated by the graphic extension of easy understanding in the accompanying drawings, these accompanying drawings comprise general network architecture diagram and channel aggregation and subchannel subdivision graph, it only illustrates those details related to the present invention, in order to avoid the disclosure is by for the those skilled in the art that benefit from description herein conspicuous details being fallen into oblivion.
With the RF communications network architecture diagram of attention directing Fig. 2, it is corresponding to Fig. 1 of cited above ' No. 753 application now.As shown in Figure 2, this network comprise the network hub or promptly ' master ' terminal unit website 10 and ' a plurality of ' long-range ' terminal unit (RTU) website 12 at the spectral reuse transceiver place of disclosed type in applying for for No. 753.As mentioned above, the configuration parameter that is used to control its operation except that communication controler by these transceivers be according to main channel aggregation subchannel of the present invention skip philosophy come predefined with clear channel assessment routine (its by transceiver carry out with locate its can between the available subchannels of jumping) search field be defined in permission and give the mode of predetermined channel of one or more main users, the framework of this transceiver there is no change.
With regard to the framework and operation of the transceiver that elaborates in ' No. 753 applications, the following description of it will be in this repetition. will replace sets forth the link utilization controlling mechanism based on spectrum activity that the communication controler by transceiver adopts and its clear channel assessment routine is defined in the main channel that identifies especially---and specifically those (disconnecting typically) main channels of the main users of licensed one or more regulation to given user's frequency band (for example 217-220MHz frequency band) and the gathering of corresponding each bandwidth produce effectively so that radio energy is used to the mode of the total bandwidth of broadband application.
Target for this reason, according to method for congregating of the present invention, and the more general clear channel assessment routine that is similar to ' describes in No. 753 applications but be defined in the channel aggregation bandwidth that (all) main users of regulation are given in permission, home site is periodically initiated clear channel assessment routine, and it is based on only to the collect tabulation of the main channel that can use in broadband application for main users of licensed inspection of giving the main communication channel of the one or more main users specifically identify.This main channel allocation information that can be directly obtains from FCC is used to a priori to set up the configuration parameter of transceiver of the main users of these regulations, and so clear channel assessment routine will only be limited to preassigned channel of interest.The main channel of tabulation of compilation will be thus in the aggregate band current with not ing use and therefore can be assembled in corresponding each subsets of sub-channels main those channels of the subchannel that in broadband application, uses of channel user for being subdivided into for (all).
One or more main users means the present invention and not only can be used for assembling the licensed main channel of giving unique user, has determined ' to converge ' a plurality of users' of its resource main channel to increase bandwidth capacity but also can be used for assembling licensed giving.As the indefiniteness example, the city may determine its main channel aggregation is become single aggregate band with small towns emergency service supplier.As described above, because distributing to these users' channel is that priori is known, therefore only be exactly to dispose the configuration parameter of the spectral reuse transceiver of applying for for ' No. 753 so that it only is defined in the problem of those channels that have been assigned to user interested to the search of usable frequency.For transceiver, channel is exactly a channel.Transceiver is operated on any channel that identifies according to its configuration parameter.
Thus, in the situation of the transceiver operation in ' No. 753 applications, described like that---except when host node transmits message, each remote user sites according to come by the known pseudorandom jump sequence of all user's priori of aggregate band sequentially progressively by and monitor the previous message that may send it from (' gathering ' frequency band) current clear channel list of master unit acquisition with searching to by home site.During the official hour interval, during the preamble period such as any message that is transmitted by home site, whole (6.25KHz) subchannels in each this type of user's the transceiver scanning aggregate band or frequency groove are to seek the appearance of RF energy.Any frequency groove that comprises the energy that is higher than defined threshold all is marked as non-clear channel, and all the other channels of aggregate band are marked as the clear channel that is available for the broadband signalling application.
Whenever remote site notices that when changing on its clear channel assessment, it reports to home site with this on every possible occasion.When home site had received clear channel list from all remote sites, it logically made up whole clear channel list from all remote transceiver of being inquired to produce composite clear channel list.
This composite clear channel list be stored in the transceiver of home site and in these clear channel according on of the regulation of PN sequence selection to all these remote transceiver broadcasting, wherein clear channel is optionally used between the user of aggregated channel frequency band by this PN sequence.When clear channel list was received at corresponding each remote transceiver place, it was stored.
Be all communicate by letter all by synchronously by rights (on clear channel list and transceiver traversal or ' jump ' meanings) between the user who guarantees this network that the clear channel (preamble channel) that the priori that the transceiver of home site all monitors in each remote transceiver is set up upward transmits initial message by the order of the clear channel clauses and subclauses institute warp of this tabulation.This initial message comprises aggregate clear channel list, preamble channel (and next preamble channel), PN sequence tap list and is the PN seed that lasts definition initial channel and jump sequence of upcoming transmission paroxysm.In case remote transceiver has received initial message, described in just applying for as ' No. 753, this transceiver transfers to normal multiple access pattern.Obtain to adopt the further details of transceiver of the present invention thereupon, can be with attention directing ' No. 753 application.
Now with attention directing Fig. 3, the main users channel segments of a plurality of disconnections of the example of its diagram Fig. 1 described above and different bandwidth (50KHz, 25KHz, 12.5KHz and 6.25KHz) is become the mode in compound channel space 15 by ' gathering ' according to the present invention, and this gathering of main channel is subdivided into a plurality of equibands (for example 6.25KHz) narrowband subchannels that is associated in the sub-divided channel space 16.As described earlier, the subscriber channel that disconnects means in total radio bands 11, the fragment 12 that has another one or more a plurality of unallocated bandwidth of obtaining the permission person for main channel to interweave, it occupies two or more and has been assigned to one or more part that (or a plurality of) stipulate the radio-frequency spectrum between user's the main channel 14.
As a result of, although the summation of the individual bandwidth of corresponding each subscriber channel 14 may produce big relatively accumulation or total bandwidth---it is if the continuous signal of communication of any kind (including but not limited to high-bandwidth video/picture signal) basically that just can hold, but (non-subscriber channel) bandwidth 12 that interweaves causes user's whole licensed bandwidth to be broken into relatively little bandwidth 14, and this has limited the potential utilance of the radio of the fixed frequency of routine described above or manually channelizing to whole subscriber channel bandwidth.
Yet, according to bandwidth aggregation methodology of the present invention, use is to the priori of this distribution of the main users channels 14 that disconnect in the main users frequency band 11, just can utilize ' clear channel assessment of the transceiver of No. 753 applications and subchannel frequency hopping function make this transmitting-receiving function that its frequency spectrums of operation only is limited in the main channel band 11 of user those main users channels 14 of distribution especially.Illustrate as diagram in Fig. 3, the individual aggregation of bandwidth that can be expressed as this type of channel this restriction of transceiver frequency spectrums of operation becomes compound channel space 15, and the channel 14 of corresponding each narrow bandwidths is illustrated as adjoining on the frequency spectrum to illustrate sizable total bandwidth available in these channels each other in the frequency band 11 therein.
Therefore, in shown example, the channel 14 of corresponding each disconnection of the main users channel band 11 of Fig. 1 is illustrated as being become the relation of adjoining mutually as the aggregated channel space 15 that comprises subscriber channel 25-20-20-21-20-21-22, these subscriber channels to represent as a whole than any much all wide total bandwidth in these disconnection channels by ' mapping ' effectively.As just illustrating in its lower section, aggregated channel space 15 is subdivided into the subchannel of a plurality of relative arrowbands that are positioned at sub-divided channel space 16.Such as, but not limited to numerical data or vision signal etc. relatively the signal in broadband (its data rate is much wideer than of any individuality in the narrow band channel 14 of these disconnections) be modulated onto just on these subchannels, and transceiver No. 753 apply for cited above ' just in description mode and the communication session of hub or home site during between these subchannels, jumping.The complex spectrum that it should be noted that channel space 15 is represented and is not meant that these channels 14 self thereby it becomes and adjoins mutually by so frequency displacement or change.Subscriber channel 14 remains unchanged.Definitely, this composite spectral space illustrate ' the transmitting-receiving function of No. 753 applications uses it for the whole or total bandwidth that broadband signalling is used by means of its subchannel frequency hopping function.
In the example of Fig. 3, each subchannel in the sub-divided channel space 16 has the bandwidth corresponding to channel width fragment the narrowest in all subscriber channels of being assembled.In the example shown, the narrowest subscriber channel bandwidth is that 6.25KHz is wide; Therefore each subchannel in the sub-divided channel space 16 all is the wide subchannel of 6.25KHz.Thus, in sub-divided channel space 16, the wide subscriber channel 25 of the single 6.25KHz of channel space 15 will produce the hopped sub-channels 24 of single 6.25KHz, and each 12.5KHz subscriber channel 20 of channel space 15 will produce a pair of 6.25KHz hopped sub-channels 17 of adjoining mutually.In a similar manner, each 25KHz subscriber channel 21 will produce 4 subchannels in the channel space 15, it comprises ' outward ' the 6.25KHz subchannel 18 that ' outward ' edge of two 25KHz subscriber channels that are associated with it adjoins, and ' interior ' 6.25KHz subchannel 19 of adjoining of the centre frequency of two 25KHz subscriber channels that are associated with it.Similarly, the 50KHz subscriber channel 22 of channel space 15 produces two pairs of ' interior ' 6.25KHz subchannels 22 that adjoin mutually and two pairs of ' outward ' 6.25KHz subchannels 23 that adjoin.
Now, although the channel space of example shown 15 be shown as including come from the channel aggregation that is arranged in single frequency band obtain the distributing user channel, it should be understood that, be without loss of generality that the continuous channel space can be assembled from the subscriber channel that is arranged in a plurality of frequency bands.It shall yet further be noted that term ' frequency band ' is not any one or the several specific part that is defined to radio spectrum.For example, it can cover the gamut (UHF frequency band) of UHF frequency.Replenish ground or alternatively, it also can contain the administrative of bigger frequency band or supervision segmentation, such as 420-450MHz UHF frequency band, perhaps littler police service frequency band in the 420-450MHz frequency band.
Because the function of the transceiver of describing in ' No. 753 applications comprises it according to method for congregating of the present invention frequency hopping and the information of interest signal is modulated to ability on these subchannels that jump to optionally between the individual or subclass of any selected number in whole (6.25KHz) subchannels of this (gatherings) channel space or these subchannels in a controlled manner, so this transceiver can be optimized its utilization to total available bandwidth of all these disconnection subscriber channels of being mapped to aggregated channel space.This provides surpasses conventional fixed frequency or the wireless remarkable performance advantage of manually prompt change.
For example, because ' the selective frequency hopping radio of No. 753 applications can distribute in the whole gathering of subscriber channel between (segmentation subchannel) and optionally jumps, so it can be provided at the remarkable gain in the efficiency of throughput gain that is given by Packet Multiplexing.In the situation of voice application, for example Chang Gui simulation is with finishing calling by saying that promptly radio is possibly under the disabled situation of desired distribution.That is, if do not have the 25KHz subscriber channel to use, even if then this radio can not dial-out call for the 25KHz radio of routine---there are two or more 12.5KHz subscriber channels to use.On the other hand because use in the method for the invention ' the selective frequency hopping radio of No. 753 applications can be between any subchannel in the channel space of assembling frequency hopping, so it just can obtain to finish this calling desired (25KHz) bandwidth.
Can recall the digital radio electric energy with scalable or optionally service quality and voice or picture quality provide voice, video and data, services ability.In addition, it is not ready-made available various data, services that the idle capacity in the aggregation network can be used in routine or cluster analog voice services, comprises ethernet bridging and IP.Method of the present invention makes the wireless function of spectrum reuse described in applying for for ' No. 753 can assemble various licensed user bandwidth, thereby the user just can enjoy these and other services.
For example, a tissue may only have the analog radio of routine or cluster, and therefore can not obtain such as ethernet bridging, IP (Internet protocol) use and other etc. digital service.By the bandwidth that the spectral reuse transceiver system of using described in applying for for ' No. 753 is assembled multiple disconnection, the user just can enjoy digital service.The user can adopt the gathering bandwidth on the degree of suitable respective organization separately.For example, the user who assembles bandwidth can continue to use its analog radio and use it for the IP application by normal mode.Similarly, the user can with described in ' No. 753 applications and be configured to the radio of assembling bandwidth according to the present invention and replace in its analog radio some or all, to utilize digital service and high-throughput more as required.
As described briefly above, the individual ground of being shared by the set of tissue may have relatively little distribution but have the example that obtains the distributing user frequency band of big relatively distribution as a whole the 450-470MHz frequency band that is the U.S..This frequency band is to such as various public safety colonies such as fireman and police and some are commercial and other application are available.Some or all participants that allow to assemble in bandwidth that assemble this frequency band all can obtain the much bigger dynamic bandwidth of scope, and use for main memory is new possibility is provided.
A kind of this type of application relates to and compiles all public safeties distribution; This makes various public security organizations can continue to use its existing radio assets, and the needs by new service add new radio assets simultaneously.An example of this type of new service is to provide such as key images data such as architectural drawings to the fire department personnel in real time earlier before allowing the fireman enter building in danger.Provide view data generally to require to use IP service, and current its for many public security organizations, be disabled.For example, a plurality of public services that the gathering bandwidth that provides on the 200KHz order of magnitude is provided distribute will hold a plurality of subclass that 40 (4KB) subchannels are arranged, and its each compound bandwidth is 160Kb, and it just can transmit data and/or image.
Bandwidth aggregation methodology of the present invention also can be used for providing in order to the digital network of the communication (interoperability manipulation) between the different public security organizations to be provided.Estimate at present that under the situation that in preplanning, not have significantly to change this type of was communicated by letter before 2023 will can be extensively not available in the U.S., and its cost is wanted 60,000,000,000 dollars.Using the present invention to come aggregate public safety bandwidth allocations just to make can be in network layer but not physical layer realizes interoperability manipulation.This provides significant advantage, because it is possible more than requiring (from various manufacturers) all devices to have identical Radio Physics layer to use the procotol (such as IP) set up to reach interoperability manipulation.Using the present invention to come aggregate public safety bandwidth to be used for the internet inserts and for example will allow the police to catch information about suspect driver rapidly.Provide the internet to insert in this way and also will be the example supply channel that the architectural drawing image can be used for the fire department personnel cited above.
The public safety bandwidth that the present invention also can be used for disconnecting is gathered into the channel that can be described as ' event coordination channel '.This type of channel can be used for providing special service, and by these special services, various public security organizations just can obtain the information about public safety ' incident ' such as fire, blast or hostage's circumstances etc.Ideally, this event coordination channel is drawn together for all public services and is organized all available single service, and plays the effect of comparing more complete and more consistent information with a plurality of parallel services (or even worse ground, do not have this type of service) that produces.The common available Content Management System (CMS) that this type of aggregation of bandwidth allows to have various level of securitys is shared, thereby but is having event information time spent that becomes jointly to produce event information.The user of this service can select from the list of thing on the radio access device to check the information of concrete incident.
Aggregate public safety bandwidth allows radio to return back to peering under the situation that can not contact radio repeater.This locality communication at the website place that this permission public safety worker is working.Moreover, because radio energy is remotely managed, therefore if necessary,, can select User Priority for example based on environment or incident.For example, big building fire may require to give fireman and some other public safety colony bandwidth priority.Flood, forest fire, terrorist activity, hostage's circumstances or other incidents may be brought new priority groups.A kind of method of management priority is to include Electronic Serial Number (ESN) in radio in, and center management system can be provided with current priority in the radio in network by this.ESN can comprise that sign is for example organized, the son field of this in-house classification and subclass.
Wireless transponder has wire connectivity to become can to operate under transponder-transponder pattern as backup in the disabled situation between transponder.This provides the robustness that strengthens for network.Transponder is poll its adjacent equipment and return back to (may have the bandwidth of minimizing) dedicated radio link on cable network sustainably.But the user that another advantage of the present invention is it to be allowed to be allowed outside the colony can adopt the bandwidth of compiling on secondary use basis.This provides the utilance higher to radio bandwidth.In the situation of public safety frequencies, ESN mechanism is used in disable secondary users during the public emergency situation.
Also can adopt ' Interference Detection (clear channel assessment) function of spectral reuse transceiver of No. 753 applications makes the mixing of conventional and digital radio can share the continuous channel space that gathering disconnection subscriber channel result causes.As above and ' No. 753 the application described in, although Interference Detection is generally used for avoiding and mainly obtains the permission person or other secondary permission persons of obtaining disturb, the interference check function of spectral reuse transceiver can be used for detecting with aggregate band in adopt the conventional wireless activity of the subscriber channel in the aggregate band on the basis of other radio equalitys.Because the cost of a whole set of equipment replacement, obtain the permission person and have motivation and allow analog-and digital-wireless mixing; Thus, some analog radios may not continue operation with changing, and network is enjoyed advantage of the present invention, thereby are that new installation or displacement radio promote spectrum efficiency in displacement project stage by stage.
As figuring out from the above description, the clear channel of the spectral reuse transceiver by utilizing ' No. 753 applications detects and the frequency agility function, bandwidth of the present invention uses control method to make receiver can effectively the subscriber channel ' gatherings ' that disconnects be become the whole overall of potential available bandwidth, its frequency spectrum latitude of emulsion to be enough to reach the relative high bandwidth requirement (such as, but not limited to the transmission of data and/or video) of the conventional regulation that otherwise can't satisfy based on single-channel radio at least.The frequency agility function of spectral reuse transceiver of ' No. 753 applications is used to optionally jump between the subchannel of different separately subsets of sub-channels, and wherein these subsets of sub-channels are to assemble to pseudorandom between all available subchannels that have been subdivided into from aggregate band.
Though we have illustrated and have described according to embodiments of the invention, it should be understood that the present invention is not defined to this, but as is known to the person skilled in the art numerous changes and modification can be arranged, therefore we do not wish to be defined to details shown and that describe herein, and are intended to contain conspicuous all this type of change and modifications for those of ordinary skills.
