Technical field
The present invention relates to the multi-service dynamic resource allocation apparatus in a kind of communications network system, this communications network system and multi-service dynamic resource allocation method.
Background technology
Due to the fast development of the day by day universal of intelligent and portable equipment and various communication terminal, multifarious business creates very large impact to communications network systems such as existing mobile cellular networks; Meanwhile, the Transformation Tendency of network configuration is progressively transitioned into heterogeneous network framework from original homogeneous network.So holding more business while that how more effectively distribution and management of frequency spectrum resource better meeting user's request in network system just becomes a key issue.
The physical layer resources casting aside various complexity is distributed, and we can think that existing communication system is roughly divided into two classes frequency spectrum resource: the resource of a class shared by control channel, referred to herein as control signal resource; Another kind of resource shared by the content-data in transmission miscellaneous service, referred to herein as data transmission resources.
Due to the diversity of business related in communication network, in communications network system, in order to transmit the control signal resource that takies required for certain business and data transmission resources is different.The signaling consumption such as, produced in instant messaging and the ratio of accessing cost for data are considerably beyond the ratio of the signaling consumption needed for video stream traffic and accessing cost for data, that is, in instant messaging in order to the resource ratio transmitted shared by data transmission resources that instant message uses to be far smaller than in video stream traffic in order to transmitting video-frequency flow but the resource ratio at data transmission resources place.
But, in existing communication system, the allocation proportion of control signal resource and data transmission resources clearly divides and uses, that is, when existing resource, to control signal transmission, which Resourse Distribute is fixing to transfer of data to which Resourse Distribute, applies for the resource that this business uses in the framework that each business can only be determined in this transfer resource character.Thisly do not consider that the design of multi-service characteristic obviously can reduce system resource allocation efficiency, throughput and access rate.
Such as, carried out analyzing and summing up for the flow information of multiple business and corresponding control signal occupation condition in 3GPP TR36.822, and the discontinuous reception mechanism proposed for small-flow service (such as instant messaging) reduces the wasting of resources further.

First, the communications network system being suitable for multi-service dynamic resource allocation apparatus of the present invention is described.Communications network system is generally divided into homogeneous network system and heterogeneous network system.
Fig. 1 is the structure chart representing the homogeneous network system can applying multi-service dynamic resource allocation apparatus of the present invention.Homogeneous network refers to the network that the Structure and function of each base station of this network system of composition is identical.The homogeneous network be made up of three base stations 30-1,30-2,30-3 is schematically shown in Fig. 1.Wherein, each base station 30-1,30-2,30-3 have respective local resource control 20-1,20-2,20-3 respectively, and the resource in the honeycomb that this local resource control 20-1,20-2,20-3 cover base station controls.
In addition, in order to the management of each honeycomb of integration, can also comprise centralized resource manager 10 in homogeneous network system, this centralized resource manager 10 carries out unified management to the honeycomb forming homogeneous network system.
Fig. 2 represents the heterogeneous network system structure chart can applying multi-service dynamic resource allocation apparatus of the present invention.Heterogeneous network refers to that the Structure and function of each base station of this network system of composition can be different network.Two class network cells are illustrated, i.e. macrocellular and cellulor in figure, wherein, the corresponding macrocell base stations 40 of macrocellular, the corresponding small cell base station 41 of cellulor.
In the framework of heterogeneous network system, macrocellular and cellulor can form overlapping covering, and the coverage of macrocellular is greater than the coverage of cellulor, and the resource that macrocellular takies is also higher than the resource that cellulor takies.Further, although not shown, each macrocell base stations 40 or each small cell base station 41 have the local resource control managed the resource of each cellular autofluorescence respectively.

According to the difference of application equipment of the present invention control range in a network, the control signal resource that multi-service dynamic resource allocation apparatus manages and the scope of data transmission resources also different.But the major function that this multi-service dynamic resource allocation apparatus has is identical in different communication network system.That is, in homogeneous network system, if apply the present invention in the local resource control of certain base station, then the control signal resource in the scope that covers this base station of multi-service dynamic resource allocation apparatus of the present invention and the allocation proportion of data transmission resources manage.On the other hand, when applying the present invention in centralized resource manager, the allocation proportion of multi-service dynamic resource allocation apparatus of the present invention to the control signal resource in the scope of all base station coverage that this centralized resource manager manages and data transmission resources carries out unified management.
Similarly, in heterogeneous network system, although the type forming the network type of heterogeneous network system and honeycomb is not identical, but the local resource control of different cellular basestation also can have multi-service dynamic resource allocation apparatus of the present invention, thus the allocation proportion of control signal resource in the scope that covers of the cellular basestation dissimilar to this and data transmission resources manages.Even if the scope that different honeycomb covers exists overlapping, do not hinder application of the present invention yet.
Referring to accompanying drawing, the preferred embodiment of the present invention is described.
(the first execution mode)
In the first embodiment, the situation that the allocation proportion of control signal resource multi-service dynamic resource allocation apparatus of the present invention be included in the cell range that manages local resource control in local resource control and data transmission resources is distributed is described.
Fig. 3 is the module frame chart of the local resource control 20 illustrated in the first execution mode.Local resource control 20 can be that independently device entity also can be the control module be present in base station.As shown in Figure 3, local resource control 20 comprises network interface unit 402, acceptance division 403, sending part 404, memory cell 409 and local resource control unit 401.Each several part is connected by bus.
Network interface unit 402 is responsible for providing the network interface between other equipment in the network such as local resource control and centralized resource manager of this base station.Acceptance division 403 is responsible for receiving the decision-making, message etc. that are sent by centralized resource manager; Sending part 404 is responsible for sending message, report etc. to centralized resource manager.
Resourse Distribute record sheet 410 and application resource demand history table 411 is preserved in memory cell 409.Have recorded the Resourse Distribute recorded information of the resource allocation conditions representing this base station in Resourse Distribute record sheet 410, specifically, this Resourse Distribute recorded information represents the existing allocation proportion of local control signal resource and data transmission resources.Have recorded in application resource demand history table 411 each application corresponding to resource (comprising control signal resource and data transmission resources) conditions of demand so that decision package 407 carries out resource allocation decisions.
Local resource control unit 401 comprises application recognition module 405, resource distribution module 406, decision-making module 407 and update module 408.
Wherein, application recognition module 405 is responsible for the application application identifying that user proposes, and identifies the kind of the communication service in communications network system.
The user that decision-making module 407 is responsible for collecting according to this base station applies the record sheet preserved in application information and memory cell 409, utilizes default algorithm or threshold value to carry out computing, makes the decision-making of Resourse Distribute.Specifically, resource requirement recorded information in application resource demand history table 411 corresponding to the communication service that the Resourse Distribute record sheet 410 preserved in memory cell 409 and recognition unit identify, determine the allocation proportion of control signal resource and data transmission resources, the control signal resource of determined allocation proportion can be met business that execution user applies for and needs and data transmission resources.Concrete decision making algorithm is aftermentioned.
The Resourse Distribute record sheet 410 preserved in the allocation proportion and memory cell 409 of the control signal resource that decision-making module 407 determines and data transmission resources is inconsistent, the allocation proportion of the control signal resource that resource distribution module 406 determines according to decision-making module 407 and data transmission resources, distributes the control signal resource in the honeycomb of place, base station and data transmission resources.
In addition, the allocation proportion of the above-mentioned control signal resource that updating block 408 determines according to above-mentioned decision package and data transmission resources, upgrades the Resourse Distribute record sheet 410 preserved in memory cell 409.
Wherein, the modules in local resource control unit 401 is performed by processors such as central processing units.Further, local resource control unit 401 and memory cell 409 are formed " multi-service dynamic resource allocation apparatus " of the present invention.
Fig. 4 is the figure of the form that the Resourse Distribute record sheet 410 that the local resource control in the first execution mode is preserved is described.Exemplify out an example of the form of Resourse Distribute record sheet 410 in the diagram.Because this Resourse Distribute record sheet 410 is only for local decision-making, so only need preservation 3 projects, respectively: Resourse Distribute ratio 701, record and currently distribute to the ratio of this honeycomb for the Resource Block Resource Block total amount of honeycomb therewith of control signal (or transfer of data), this ratio is the decimal between 0 ~ 1.Such as Resourse Distribute ratio is 0.4(control signal accounting) then represent that current this honeycomb of distributing to accounts for 40% of this cell resource block total amount for the Resource Block of control signal; Control signal real resource takies situation 702, record resource that up till now honeycomb was actually used in control signal ought account for the ratio of distributed control signal resource, this ratio is the decimal between 0 ~ 1, it is 0.6 that such as control signal real resource takies situation, then represent and resource that up till now honeycomb was actually used in control signal ought account for 60% of distributed control signal resource; And transfer of data real resource takies situation 703, record resource that up till now honeycomb was actually used in transfer of data ought account for the ratio of distributed data transmission resources, this ratio is the decimal between 0 ~ 1, it is 0.6 that such as transfer of data real resource takies situation, then represent and resource that up till now honeycomb was actually used in transfer of data ought account for 60% of distributed data transmission resources.
In addition, Resourse Distribute ratio 701 also can be control signal resource and the ratio of data transmission resources, as long as can show allocation proportion relation between control signal resource and data transmission resources, its expression-form can be any.
Fig. 5 is the figure of the form that the application resource demand history table 411 that the local resource control in the first execution mode is preserved is described.The project that application resource demand history table 411 is preserved is respectively: application numbers 801, records the numbering that each application is corresponding, for unique identification services; Required control signal resource 802, representing the amount that will perform the control signal resource needed for business of application numbers 801 correspondence, recording for transmitting the control signal resource consumed needed for this application; Desired data transfer resource 803, representing the amount that will perform the data transmission resources needed for business of application numbers 801 correspondence, recording for transmitting the data transmission resources consumed needed for this application; And other attributes 804, record the apply property that other can be used for decision-making, such as priority, business value etc., this attribute can determine according to system requirements, also can omit other attributes 804.
Wherein, required control signal resource 802 and desired data transfer resource 803 also can be considered as simply for transmitting the bandwidth taken needed for corresponding application.
The resource allocation mechanism that first execution mode of the present invention is corresponding is dynamic resource shared mechanism.
It is exactly do not consider to the allocation proportion that control signal resource and data transmission resources are fixed in existing system that so-called dynamic resource is shared, but shares all resources, and according to business demand current in honeycomb, the carrying out of the resource dynamic in each honeycomb is distributed.Because the demand of often kind of business to control signal resource and data transmission resources is different, so each honeycomb distributes the ratio (this ratio can be looked different in each honeycomb) of control signal resource and data transmission resources according to the service request of oneself active user, like this, the resource utilization in honeycomb can be improved, improve throughput of system and access rate.
Fig. 6 is the figure of the illustrative examples of system resource configuration when representing that multi-service dynamic resource is shared.In Fig. 6, the resource of a honeycomb is divided into control signal resource and data transmission resources.Only resource distribution situation when resource-sharing is described is present in honeycomb for video and instant message two kinds of business in figure.It should be noted that, transmission of video business only needs take little a part of control signal resource and take more data transmission resources, and transmitting instant messaging by contrast needs take more control signal resource and only need to take little data transmission resources.Therefore, if containing more video traffic request in existing cellular, this honeycomb can distribute less control signal resource and distribute more data transmission resources, i.e. Resourse Distribute ratio 701 less (shown in as leading in (1) video traffic in Fig. 6); If containing more instant messaging request in existing cellular, this honeycomb can distribute more control signal resource and distribute less data transmission resources, i.e. Resourse Distribute ratio 701 comparatively large (shown in as leading in (2) instant messaging in Fig. 6).
Below the flow process of the Resourse Distribute performed by local resource control 20 is illustrated.
Fig. 7 represents in the first execution mode by flow chart during local resource control execution multi-service Dynamic Resource Allocation for Multimedia decision-making.First, decision process proposes service request by user and initiates (step 1001), thus enters step 1002, performs application identification process by application recognition module 405, identifies the application numbers that this customer service request belongs to which kind of application and its correspondence.
Then, the decision-making module 407 of local resource control unit 401 enters the process (step 1003) of inquiry application resource demand and Current resource distribution condition, according to the Resourse Distribute record sheet 410 inquired about according to the application numbers identified in step 1002 in memory cell 409 and application resource demand history table 411, control signal resource 802 and desired data transfer resource 803 needed for this application of record in Resourse Distribute record sheet 410, determine the resource requirement of this application.Take situation 702 and transfer of data real resource according to the Resourse Distribute ratio 701 of current honeycomb of record in application resource demand history table 411, control signal real resource to take situation 703 and determine that Current resource distributes and service condition.And then entering Decision Resource assigning process (step 1004), decision-making module 407 carries out decision-making according to the algorithm preset and threshold value.According to kind and the Query Result of the communication service identified, determine the allocation proportion of control signal resource and data transmission resources.
Then, determined control signal resource and the allocation proportion of data transmission resources and the Resourse Distribute ratio 701 of current honeycomb are compared, judges whether to need to redistribute resource (step 1005).
When being judged as not needing to redistribute resource (step 1005: no), winding-up Dynamic Resource Allocation for Multimedia flow process (step 1009).
When being judged as needing to redistribute resource (step 1005: yes), enter the process (step 1006) redistributing resource, by the resource distribution module 406 in local resource control unit 401 according to comprising the result of decision how redistributing control signal resource and data transmission resources, concrete this resource allocation decisions of execution.
After being finished, send Resourse Distribute updating record (step 1007) by sending part 404 to centralized resource manager 10.After this updating record received by centralized resource manager 10, the content update of this report can be utilized to be stored in the record sheet of each base station case of expression in centralized resource manager 10, thus to grasp the Current resource distribution condition (step 1008) of each base station.This flow process (step 1009) is terminated after renewal.
In addition, when base station operates separately and does not have the centralized resource manager 10 of integration multiple base station, the step 1007 represented by dotted line in Fig. 7,1008 also can be omitted, and does not namely carry out the flow process of distributing with regard to ending resource the report action of central explorer 10.
The algorithm of employing when below illustrating that decision-making module 407 carries out decision-making.
First, decision-making module 407 carries out decision-making according to the algorithm preset and threshold value, its object is to the allocation proportion of optimal control signal resource and data transmission resources to meet the different demands corresponding to different business.Therefore, it is possible to the algorithm obtaining the allocation proportion of the control signal resource after optimizing and data transmission resources may be used to the present invention.
Such as, as shown in Figure 6, because the ratio of transmission of video business with the control signal resource required for transmission instant messaging and data transmission resources there are differences, therefore, when to identify above-mentioned communication service be instant messaging to application recognition module 405, decision-making module 407 improves the allocation proportion of above-mentioned control signal resource and data transmission resources, when to identify above-mentioned communication service be video stream traffic to application recognition module 405, decision-making module 407 reduces the allocation proportion of control signal resource and data transmission resources.Adopt above strategy can adopt different control signal resources and the allocation proportion of data transmission resources according to the difference of type of service.
In addition, data transmission resources consumes more business and is not limited only to video stream traffic, such as, also comprise video traffic, Video Conference Service, network backup and large data upload downloading service etc.Further, control signal consumes more business and is also not limited only to instant messaging, such as, also comprise machine and machine communication (M2M) business etc.
Different pro rate grades can be preset according to the different characteristics of each business, and then according to the identification to business, carry out withdrawal ratio allocation level by decision-making module 407 and carry out simple decision-making.
In addition, decision-making module 407 also can adopt following algorithm.
First, calculate new Resourse Distribute ratio required after increasing new opplication, take situation 702 and transfer of data real resource takies on the basis of situation 703 inquiring the control signal real resource in the existing cellular in Resourse Distribute record sheet 410, add required control signal resource 802 and the desired data transfer resource 803 of this application of record in application resource demand history table 411 respectively.Then, the allocation proportion of control signal resource and the data transmission resources made new advances is calculated according to following calculating formula:
Using the result of above-mentioned calculating formula after new Resourse Distribute ratio, decision-making module 407 carries out the judgement of following condition further, namely, for ensureing the stability of system, system can be set by system for changing Resourse Distribute ratio setting this thresholding of Upper threshold threshold value T(in advance as required), this threshold value is the decimal between-1 ~ 1, as-0.1 ,-0.2,0.1,0.2....Further, will be judged as that the condition of " needing to carry out resource to redistribute " is set as: 1) new Resourse Distribute ratio-Current resource allocation proportion >T; And the control signal resource 2) under new ratio and data transmission resources can meet current and newly add control signal resource and the data transmission resources demand of application.Then adjudicate as no (not needs carry out resource redistribute) if do not met any one condition above-mentioned.
In addition, decision-making module 407 can adopt any algorithm that traffic performance can be utilized to obtain the allocation proportion of control signal resource and the data transmission resources optimized, and existing various algorithm also can be utilized to realize the optimization of pro rate.
In addition, present embodiment describes update module 408 upgrades Resourse Distribute record sheet 410 content according to the decision-making of decision-making module 407, but, also can omit update module 408, resource distribution module 406 directly distributes control signal resource and data transmission resources according to the result of decision of decision-making module 407.
(the second execution mode)
The resource allocation mechanism that second execution mode of the present invention is corresponding is also dynamic resource shared mechanism.
In this second embodiment, to multi-service dynamic resource allocation apparatus of the present invention dispersion to be included in local resource control and centralized resource manager thus the situation that the allocation proportion that centralized resource manager each cell range to subordinate carries out unified control signal resource and data transmission resources manages is described.
In addition, give identical Reference numeral for the parts identical with the first execution mode, and the repetitive description thereof will be omitted.
Fig. 8 is the module frame chart of the centralized resource manager 10 represented in the second execution mode.This centralized resource manager 10 can be that independently device entity also can be present in the control module in the equipment such as gateway.

(the 3rd execution mode)
The distribution mechanism of the resource-sharing illustrated in first, second execution mode carries out decision-making in real time when the business of initiation to carry out Resources allocation.This distribution mechanism is relatively flexible, but higher to the dynamic requirements of system, also may impact the stability of system simultaneously, in the heterogeneous network system especially mixed in multiple cellular-type, may cause burden to some equipment.Therefore, in the third embodiment, in conjunction with following by the heterogeneous network framework of widespread deployment, illustrate that multiple decision-making is initiated differently composed.
When current network framework is for heterogeneous network shown in Fig. 2, if comprise macrocellular and cellulor in communications network system.Meanwhile, the resource of occupying due to macrocellular and cellulor is different, and the division of resources ratio of its correspondence is also different.
Figure 15 illustrates the schematic diagram based on cell resource segmentation during heterogeneous network division of resources in the 3rd execution mode.For the convenience illustrated, only honeycomb is divided into two kinds in figure: macrocellular and cellulor.The resource that macrocellular occupies is by W mrepresent, the resource that cellulor occupies is by W mrepresent.The Resourse Distribute ratio of macrocellular is represented by α, and the Resourse Distribute ratio of cellulor is represented by β.Therefore, the resource distributing to control signal in macrocellular is α W m, distribute to the resource of transfer of data for (1-α) W m; The resource distributing to control signal in cellulor is β W m, distribute to the resource of transfer of data for (1-β) W m.
Although only illustrate two class honeycombs in Figure 15, but this two classes honeycomb also can be understood according to deployment in the future flexibly, although namely distinguish macrocellular and cellulor, but also can have different division of resources ratios between macrocellular from macrocellular, between cellulor and cellulor, that is macrocellular can have α 1, α 2, α 3α nplant configuration, same cellulor also can have β 1, β 2, β 3β nplant configuration.Flexible configuration can be carried out according to the business characteristic in this honeycomb like this for each honeycomb, such as, in this community, video traffic (or other data transmission resources consume comparatively multi-traffic) user can adopt less α more at most, β configures, if control signal consumption is absorbed in compared with multi-traffic in contrary community, can adopt larger α, β configures.Feasibility and the flexibility of system dynamic cell function distinguishing and mark is substantially increased by the mechanism of this kind of resource difference segmentation.
Certain this kind of division of resources mechanism is not the division of resources ratio of a certain honeycomb is unalterable.Due to the feature according to telex network flow, customer flow has tidal effect in a certain area, such as office building periphery office hours customer flow is comparatively large but non-office hours customer flow is less, and periphery office hours customer flow in living area is less but non-office hours customer flow is larger.Therefore, be also contained in division of resources mechanism of the present invention to improve flexibility and the efficiency of system according to flow information or the renewal cell resource configuring condition in cycle.
Performance due to the local resource control of each honeycomb feature that is different and their location is not equal, can set the startup event of different resource allocation mechanisms.Further, the Initiated Mechanism in the local resource control of different honeycombs can be different.
Be arranged on by decision-making module in centralized resource manager in 3rd execution mode, therefore, the formation of the centralized resource manager of the 3rd execution mode is identical with the formation of the centralized resource manager in the second execution mode.In the present embodiment, division of resources decision-making management is carried out by the various honeycombs of centralized resource manager unification to subordinate.

First, carry out division of resources initialization procedure (step 1601), the division of resources ratio of each honeycomb in its administrative area is determined according to the history service resource analysis of statistics and the local resource control to each honeycomb sends Resourse Distribute initialization decision-making report by centre explorer 10, the timer of the honeycomb of initialization simultaneously, for ease of illustrating, assuming that the timer synchronization of each honeycomb.In addition, the form of above-mentioned initialization decision-making report as shown in figure 13.
Then, enter local resource service condition observation process (step 1602), the application identified according to application recognition module 405 by the monitoring modular 413 of local resource control 10 and respective resources demand, resource service condition in this honeycomb of research and application, detailed process can adopt application identification step 1002 in the Figure 10 illustrated in the first execution mode, inquiry application resource demand and Current resource distribution condition step 1003.Judge whether that there will be resource overflows (step 1603) by these two steps.
If undiscovered resources overflow hidden danger (step 1603: no), then whether then (step 1612) judge timer further, this timer can according to system requirements sets itself, such as every 4 hours, 8 hours, 12 hours then system update once configure.If timer is not then, then continue local resource service condition observation process (step 1602); If timer then, then carry out decision-making by the decision-making module 306 of centralized resource manager 10 and send decision-making report, the form of this decision-making report as shown in figure 13.By regular like this mode of carrying out decision-making, can be preset by the result of system according to traffic statistics.
Next, local resource control 10 receives this decision-making report, and according to this decision-making report change corresponding configuration.
On the other hand, if find that a certain application will cause resource to overflow (can be control signal resource also can be data transmission resources) (step 1603: yes), then enter and send resource spilling reporting process (step 1604), send resource by the sending part 404 in local resource control 20 to centralized resource manager 10 and overflow report, this resource overflows the form of report as shown in figure 18.
Figure 18 illustrates that in the 3rd execution mode, local resource control overflows the figure of reporting format to the resource that centralized resource manager sends.This resource is overflowed and is reported the project that comprises respectively: honeycomb numbering 1701, cellular-type 1702, Resourse Distribute ratio 1703, control signal real resource take situation 1704, transfer of data real resource takies situation 1705 and spilling application numbers 1706.
Report is overflowed when central explorer acceptance division 304 receives this resource, similarly enter the decision-making of centralized resource manager and send decision-making reporting process (step 1605), overflow the Resourse Distribute ratio 1703 in reporting by the decision-making module 306 in centralized resource manager 10 according to resource, control signal real resource takies situation 1704, transfer of data real resource takies situation 1705 and overflow application numbers 1706 and carry out division of resources decision-making and send decision-making report, detailed process is identical with the step 1206 in Figure 11.
When the acceptance division 403 of local resource control 20 receives (step 1606) when decision-making is reported, by reading the Resourse Distribute ratio 140 in this decision-making report, judge whether to need to redistribute resource (step 1607).
If be judged as that not needing to carry out resource redistributes (step 1607: no), then terminate this flow process (step 1611).If be judged as that needing to carry out resource redistributes (step 1607: yes), then enter and redistribute resource process (step 1608), specifically perform this resource allocation decisions by the resource distribution module 406 in local resource control unit 401.
After being finished, send Resourse Distribute updating record (step 1609) by sending part 404 to centralized resource manager 10.After the acceptance division 304 of centralized resource manager receives this updating record, update module 307 upgrades corresponding project in the Resourse Distribute record sheet 308 preserved in memory cell 302.Thus, this flow process (step 1611) is terminated.
By above action, the decision-making of division of resources can be performed when there is particular event, thus can according to the specific startup setting division of resources decision-making more neatly of this locality.
In addition, described above is the flow process of being carried out division of resources decision-making by centralized resource manager, certain division of resources decision-making also can be undertaken by local resource control, namely the decision-making module in the 3rd execution mode is installed in local resource control, timer in local resource control then or exist when resource overflows risk and perform local resource allocation decisions, is not repeated at this.
In addition.In the third embodiment, timer and monitoring modular 413 are installed in local resource control, regularly perform resource allocation decisions or perform resource allocation decisions when occurring overflowing.But, also in local resource control, only can having timer, thus regularly perform resource allocation decisions, or also only can have monitoring modular, performing resource allocation decisions when there is resource spilling.
