Information source node 11 among Fig. 3,12, all are used to provide 13 general references the node device of carrier channel or comprise that himself reaches the node device that extends from himself, well-known, information source node 11,12,13 can be the base station, the base station is the source that provides of typical carrier channel, but also can be Base Band Unit or the Remote Radio Unit in the radio frequency stretch system, although self does not produce carrier channel Base Band Unit or Remote Radio Unit, but the carrier channel from the base station is had the effect that management is controlled, thereby, in the present invention, directly or indirectly provide the equipment of carrier channel to be considered as information source node equipment these and describe, will help the reader to understand invention spirit of the present invention.
In like manner, indication overlay node 91,92,93 is not limited to antenna or antenna-feedback system among Fig. 3, and it also can comprise the repeater that is connected with antenna, maybe can comprise the Base Band Unit of radio frequency stretch system or Remote Radio Unit etc.
Generally, following carrier wave router that will be elaborated of the present invention and carrier channel scheduling method are applicable in the communication link at almost any place of communication overlay system, the object of its scheduling mainly is the carrier channel that signal used of communication link, not limited by embodiments of the invention for contained signal particular content of carrier channel and the concrete node device that relates to thereof.
The communication overlay system of Fig. 3 provides three overlay networks, is respectively:
First overlay network is made up of information source node 11 and overlay node 91;
Second overlay network is made up of information source node 12 and overlay node 92;
The 3rd overlay network is made up of information source node 13 and overlay node 93.
As previously mentioned, information source node 11,12,13 can comprise the base station of serial connection and the near-end Base Band Unit of radio frequency stretch system, overlay node 91,92,93 can comprise Remote Radio Unit that is connected with described Base Band Unit and the antenna-feedback system that is connected in series with Remote Radio Unit.Well-known, in the transmission course of the information source node of each overlay network and overlay node, all there are two communication links, be specially the down link of handling downstream signal and the up link of handling upward signal.The carrier dispatching process of carrier wave router 8 shown in Figure 3 just is being based on that the up link of each overlay network (11 and 91,12 and 92,13 and 93) and down link carry out.
Each overlay network as shown in Figure 3, a side ports of its information source node 11,12,13 equal access carrier routers 8, and the opposite side port of 91,92,93 access carrier routers 8 of overlay node.Although it is also not shown among the figure, but owing to generally baseband signal is carried out the uplink and downlink transmission that is separated with the light signal form between information source node and the overlay node, thereby the signal of carrier wave router 8 handled each overlay network all is to carry out during respectively to the up link of this overlay network and down link independent same.Specifically will in follow-up explanation, describe in detail.
Carrier wave router 8 shown in Fig. 3 mainly comprises three parts, be specially a traffic carrying capacity detecting unit 4 that mixes unit, road 2, constitutes by n professional detection module 40 (consulting Fig. 4) and a monitoring host computer unit 3 that plays the management control action, common formation scheduling unit between traffic carrying capacity detecting unit 4 and the monitoring host computer unit 3.
Mix unit, road 2 and include n communication link, be used to finish and each information source node of n overlay network and the electric connection between each overlay node, particularly, each information source node has up link and down link, insert in the up link and down link of overlay node correspondingly respectively, and make each overlay node all have the summation of the carrier channel of all overlay networks.Communication overlay system with three overlay networks only is shown in the present embodiment, thereby, variable n=3, in theory, the numerical value of n is not subjected to the restriction of the embodiment of the invention, and it can be any one positive integer greater than 2, for the convenience of explaining, in the following description, still have the example with the concrete number of n designate, those skilled in the art all know this and one refer to relation.
This scheduling unit is mainly used in the traffic carrying capacity of each carrier channel that detects each overlay node, and adds up to the traffic carrying capacity of overlay node according to the carrier channel that overlay node uses.If the traffic carrying capacity of certain overlay node near at full capacity, will be selected a relatively more idle carrier channel from another few overlay node of traffic carrying capacity, this carrier channel scheduling is come to use.The work of scheduling unit is mainly finished jointly by traffic carrying capacity detecting unit 4 and monitoring host computer unit 3.Traffic carrying capacity detecting unit 4 is made of n professional detection module 40 (consulting Fig. 4), do not have direct electrical connection between n the professional detection module 40, but electrically connect with this monitoring host computer unit 3 respectively, monitoring host computer unit 3 need carry out the pre-of parameter if adjust to each professional detection module 40 in the traffic carrying capacity detecting unit 4 on the one hand, on the other hand, each professional detection module 40 final data that produce and signal also will be submitted to this monitoring host computer unit 3 and focus on.
Fig. 4 shows the part of concrete structure of the carrier wave router 8 of the present invention of Fig. 3, it represented mix unit, road 2 in the carrier wave router 8 each to communication link and and professional detection module 40, monitoring host computer unit 3 between electrical connection and structure form.
Mix unit, road 2 and comprise n the communication link that constitutes jointly by down link and up link as shown in Figure 4, each communication link inserts in the overlay network, particularly, first overlay network of forming with information source node 11 and overlay node 91 is an example, the down link of information source node 11 inserts behind incoming carrier router 8 in the down link shown in Figure 4 immediately among Fig. 3, exports in the down link of overlay node 91 after corresponding the processing.Principle when up is identical, also is after the up link of overlay node 91 among Fig. 3 enters up link shown in Figure 4 one tunnel transmission, to be fed in the up link of information source node 11.By the combination of Fig. 3 and Fig. 4 as can be seen, carrier channel scheduling method of the present invention is to the scheduling process of a plurality of overlay networks, be actually based on to the intercepting and capturing of the upward signal of each overlay network and downstream signal, processing, reduce the former link of feed-in again and realize.
See also Fig. 4, in down link, the signal of telecommunication is intercepted and captured and be converted to information source node going into modular converter 51 places, generally speaking, transmit with light signal, the signal of telecommunication or wireless signal between information source node and the overlay node, no matter concrete signal format how, being provided with of modular converter 51 of going into herein is that mainly the conversion of signals with existing form is the signal of telecommunication that carrier wave router 8 can be discerned processing.In like manner, be provided with at the transmission end of this down link and go out modular converter 55 accordingly, its purpose is to be reduced into original signal format so that in the former link between feed-in information source node again and the overlay node with handling the back signal of telecommunication in this down link.Because transmission medium at present comparatively commonly used mostly is optical fiber, thereby present embodiment can to go out that modular converter 55 refers in particular to be that module is received/sent out to light with going into modular converter 51/.
Going into modular converter 51 and going out between the modular converter 55, according to the transmission direction of downstream signal, comprising shunt module 52 successively, close road module 53 and carrier Control module 54.
Please in conjunction with Fig. 3 and Fig. 4, the signal of telecommunication that process is gone into after modular converter 51 is handled is the downgoing baseband signal that is derived from the current information source node, it includes several and belongs to the intrinsic carrier channel of current information source node, described shunt module 52 is used for the downgoing baseband signal of current information source node is carried out shunt, be divided into n branch signal, send into closing in the road module 53 of n overlay node respectively.The closing road module 53 and distribute the branch signal that comes of each overlay node except receiving one tunnel current link shunt module 52, also receive the input of each one road branch signal of other n-1 information source node, because each branch signal has all comprised all carrier channels of the information source node under it, thereby, the road module 53 of closing shown in Figure 4 is closed behind the road in the formed composite downstream baseband signal from various information source node branch signal n, to comprise all carrier channels from all information source node, also be the summation of all carrier channels of whole communication overlay system.
Shown in Figure 4 only is a pair of communication link of carrier wave router 8, for remaining communication link too, the down link of every pair of communication link close the summation that road module 53 all obtains all carrier channels of whole communication overlay system.
Close in the composite downstream baseband signal that forms behind the road and comprised all carrier channels although close road module 53,, what carrier channels overlay node opens, and can be provided with by carrier Control module 54.Carrier Control module 54 is provided with different pad values according to the configuration information of monitoring host computer 3 to each descending carrier channel, until carrier channel is opened or closed.
Carrier Control module 54 in the down link shown in Figure 4, it can receive the instruction of described monitoring host computer unit 3, according to this instruction to controlling step by step several times by the pad value of wherein each carrier channel, when monitoring host computer unit 3 sends these carrier Control module 54 certain carrier channels of unlatching of instruction indication, this carrier Control module 54 reduces the pad value of this carrier channel step by step, until this carrier channel pad value is 0dB, at this moment is unlatching.On the contrary, close certain carrier channel if desired, then monitoring host computer unit 3 sends corresponding instruction, and the carrier Control module 54 corresponding pad values that improve this carrier channel step by step are until maximum and close.Certainly, in the down link of certain carrier channel at current overlay node, enabled/when closing, for the down link of other overlay node, this carrier channel just is in the state of closing/enabling; Also promptly, to each carrier channel of information source node, can only have this carrier channel of an overlay node to be in unlatching at most, this carrier channel of other overlay node is all for closing.Concrete certain carrier channel is enabled in which overlay node, and the scheduling unit that is made of monitoring host computer unit 3 and traffic carrying capacity detecting unit 4 determines.
Baseband signal after selecting through carrier Control module 54 is gone out modular converter 55 and converts original signal format to by described, behind the light signal form in the present embodiment, just again in the overlay node of the former link of feed-in.Import after carrier wave router 8 is handled, again in the down link of feed-in overlay node 91 from information source node 11 as shown in Figure 3.
Please in conjunction with Fig. 3 and Fig. 4, the up link of mixing unit, road 2 to the uplink baseband Signal Processing basically with down link to downgoing baseband Signal Processing contrary, but its treatment step relative complex.Particularly, the side signal transmission of pressing the uplink baseband signal to, include modular converter 51 ', professional detection module 40, carrier Control module 54 ', shunt module 52 ' successively, close road module 53 ' and go out modular converter 55 ', wherein professional detection module 40 is responsible for detecting the business of uplink baseband signal in the up link, and the result of its output directly offers monitoring host computer unit 3 and uses; Go into modular converter 51 ' and go out modular converter 55 ' then finish with down link in go into modular converter 51 and go out modular converter 55 identical functions, this not all right giving unnecessary details.The shunt module 52 ' of up link is separated into n road signal with the carrier channel of uplink baseband signal, except that one tunnel follow-up the closing the road module 53 ' that exports current up link to, other n-1 road signal exports the road module of closing of the up link of other information source node respectively to and closes the road, thus, closing in the road module 53 ' of each up link, just the n road signal from n overlay node can be carried out carrier wave and close the road and become compound uplink baseband signal.When shunt module 52 ' was separated carrier channel, the carrier channel of every road signal was corresponding with the carrier channel of its information source node, like this, this information source node just can receive all overlay networks with the corresponding carrier channel of this information source node self.Because carrier channel is mainly provided by information source node, the employed carrier channel of up link is retrained by the employed carrier channel of down link basically, thereby, in up link, also can carry out the control of enabling and closing of carrier channel, also be that carrier Control module 54 ' can be omitted, at this moment, modular converter 55 ' is reduced into signal in the up link of light signal feed-in information source node again and gets final product.
As shown in Figure 4, all has a professional detection module 40 in the up link of each overlay network, be used to finish the function of the traffic carrying capacity that detects each carrier channel, the professional detection module 40 common compositions traffic carrying capacity detecting unit 4 shown in Figure 3 in n up link.
This business detection module 40 comprises the professional monitoring means 41 of carrier wave of each carrier channel of overlay node, and the professional monitoring means 41 of carrier wave detects the traffic carrying capacity of carrier channel by known detection method, sends then to monitoring host computer unit 3; After monitoring host computer unit 3 gets access to the traffic carrying capacity of each carrier channel, open situation,, just draw the traffic carrying capacity of this overlay node the traffic carrying capacity addition of corresponding carriers channel according to the carrier channel of overlay node.
Consult Fig. 2, the work of scheduling unit also needs scheduling strategy (dispatching method), only describes with a scheduling strategy below: user preset application thresholding, so when the approaching upper limit of having distributed available traffic of the traffic carrying capacity of certain overlay node, when surpassing threshold value, just send the scheduling application.Monitoring host computer unit 3 is sought one and is used minimum carrier channel in the less overlay node of other traffic carrying capacity, then this carrier channel scheduling is used in the overlay node that sends application, makes busy overlay node can be assigned to more carrier resource.
When carrying out the scheduling of carrier channel, in the overlay node of dispatching out, the pad value of this carrier channel is increased step by step earlier, close up to maximum by carrier Control module 54; And then in the overlay node that scheduling is gone into, the pad value of this carrier channel is reduced step by step, until unlatching.This method that pad value is set step by step, the communication quality that can allow the user of current carrier channel detect current carrier channel is worsening, and the user will search for better carrier channel automatically, switches and proceeds communication in the past, and can not break, this also is one of advantage of the present invention.
Scheduling strategy can have a variety of, and content of the present invention is not subjected to the restriction of scheduling strategy.
When using optical fiber to transmit between information source node and the overlay node, go into modular converter 51 for the uplink and downlink link homonymy of unit, mixed road 2 shown in Figure 4,51 ' and go out modular converter 55,55 ' can directly adopt light to receive/send out module, when adopting cable, can adopt serial ports to receive/module, its major function is to finish the conversion of the signal of telecommunication and other form signal, and those skilled in the art all know its accommodation.
In sum, by in the existing communication overlay system of widely using, increasing the carrier wave router, use brand-new carrier channel scheduling method, set up the contact each other between a plurality of overlay networks, make it form the integral body of an organic unity, the dynamic dispatching of carrier channel each other becomes possibility, for operator, the comprehensive utilization of carrier channel no longer is to be the internal schedule of unit with the overlay network that extends based on single base station, dispatch and be based between the border, station of whole communication overlay system of all base stations, this scheduling relation can make the carrier channel resource be fully used, be difficult for causing the local period channel resource deficiency in some areas, also be difficult for causing the waste of channel resource, improved the utilance of carrier channel resource on the whole, for bringing technological change in the communications field.
The foregoing description is a preferred implementation of the present invention; but embodiments of the present invention are not restricted to the described embodiments; other any do not deviate from change, the modification done under spirit of the present invention and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within protection scope of the present invention.
