Description

A kind of load reconditioning system and method

Technical field

The present invention relates to moving communicating field, relate in particular to a kind of load reconditioning system and method.

Background technology

In the existing cell mobile communication systems, usually a big geographic area coverage is divided into some sub-districts, use low power transmitter (base station) to cover each sub-district, set up communication with the user, the covering radius of sub-district is less, but many sub-districts just can cover whole big geographic area.Simultaneously, use identical frequency, can greatly improve the utilance of frequency spectrum resource in different sub-districts; And increase the sub-district of using different frequency in the intensive zone of user, then can improve this regional power system capacity.For each sub-district, its physical resource (for example transmitting power, bandwidth, channel code resource etc.) is limited, along with the increase of its service-user, cell load is gradually saturated, certainly will cause that new user can't be access in, a series of consequences of degradation under original QoS of customer.

Conventional art uses LCC (Load Congestion Control, the congested control of load) deal with this problem, LCC reaches warning line later on by selecting the certain user to disconnect methods such as connection at cell load, and the load level is returned to a kind of acceptable level.But because LCC operation is very big for user's satisfaction influence, thus can not frequent starting, thereby can only just can start up to the edge of collapsing, and starting later load, to adjust target also be basic fixed in load.

Prior art uses the LCC module that the cell load level is adjusted, and selects some users to disconnect connection at random, so that cell load is reduced to the acceptable level, has following shortcoming when reality is used:

1, the selected operation of LCC module is too simple and crude, and is very big to the user satisfaction influence.

2, because 1, the LCC module can not frequent starting, therefore start threshold setting get very high, near the system crash edge, very risky.

3, the LCC module, can't change according to system requirements at a default thresholding flexibly to the adjustment target basic fixed of load.

4, when but duty ratio is higher when also arrive triggering the LCC thresholding, the access module has begun to refuse new user's access, so low priority user may appear because early of inserting and can keeping connect, high-priority users can not be enjoyed service all the time because access opportunity is bad phenomenon, run counter to the Provisioning Policy of User Priority.

Summary of the invention

The method of adjustment that the present invention will solve prior art is too simple, and call relation is unintelligible between the module, can't satisfy the problem of customer requirements, and the spy provides a kind of can adjust load reconditioning system and the method for load level to satisfy system requirements flexibly.

The present invention has introduced LDR (Load Reshuffling, Load Reshuffling) module, this module is independent of traditional LCC (Load Congestion Control, the congested control of load), AC (Admission Control, access control) etc. beyond the module, integrated multiple flexible operation is adjusted the load level, can be by these module invokes.Simultaneously, introduced LDM (Load Monitoring again, load monitoring) module is carried out relatively accurate monitoring and assessment for the result of load adjustment, and to reach flexible adjustment load level to satisfy the purpose of system requirements, the present invention is achieved through the following technical solutions.

A kind of load reconditioning system comprises: Load Reshuffling request module, Load Reshuffling module, load monitoring module and load adjusting module;

When described Load Reshuffling request module is discontented with the foot-eye value in the present load index, send the Load Reshuffling request to the Load Reshuffling module;

Described Load Reshuffling module receives the Load Reshuffling request; Select load adjustment action and the user who adjusts and write down selection result; The result of the action is adjusted in request load monitoring module prediction load; Carry out load adjustment action or send execution load adjustment action command to the load adjusting module;

Described load monitoring module is predicted described load adjustment the result of the action and the result is returned the Load Reshuffling module; The monitoring load index is sent the Load Reshuffling request to the Load Reshuffling module when the present load index is discontented with the foot-eye value.

A kind of Load Reshuffling method comprises the following steps:

S1. the Load Reshuffling module receives the Load Reshuffling request, comprises the desired value of loading index in the described Load Reshuffling request;

S2. the Load Reshuffling module is selected load adjustment action and is adjusted the user and write down selection result;

S3. Load Reshuffling module request load monitoring module is predicted selected load adjustment the result of the action;

S4. load monitoring module prediction load is adjusted the result of the action and will be predicted the outcome and returns the Load Reshuffling module; The load monitoring module judges whether this result satisfies described desired value, if continue step S5; If not, return step S2;

S5. the Load Reshuffling module is carried out load adjustment action or is sent fill order.

Compared with prior art, use load reconditioning system of the present invention and method and can obtain following beneficial technical effects:

1, introduces multiple operation (Action) and dynamically adjusted the cell load level.

2, LDR module is independent of outside the modules such as original LCC, AC, but can be by these module invokes.The LDR module is mainly finished the adjustment function for cell load, and the opportunity of adjusting and the target of adjustment then determined by other modules, thus the clear and definite call relation of intermodule.

3, the LDM module can be carried out relatively accurate monitor and predict to cell load, so each module can determine that dynamically cell load adjusts target according to separately demand, and comes monitor and predict adjustment result by the LDM module.

4, because the independence of LDR module is worked as load too high, new user can determine whether that needs carry out Load Reshuffling according to its priority when being rejected, and after reforming high-priority users is inserted, to embody the privilege of its high priority.LDM and LCC module also can be called the dynamic adjustment that LDR carries out cell load according to operator's predetermined strategy in to the real-time monitoring of load.

Description of drawings

Below with specific embodiment and be described with reference to the accompanying drawings the present invention.

Fig. 1 is a load regulating system structural representation of the present invention.

Embodiment

As shown in Figure 1, the described load reconditioning system of present embodiment comprises: Load Reshuffling request module, LDR module, LDM module and load adjusting module; The LDR module comprises decision-making submodule and implementation sub-module; The Load Reshuffling request module comprises LCC module, AC module; The load adjusting module comprises HO module (HandOver switches), DCCC module (Dynamic Channel Configuration Control, dynamic channel configuration control), CHS module (Channel Switch, channel type switches).

The function of each module is described respectively below:

The LDR module receives the Load Reshuffling request; Select load adjustment action and the user who adjusts and write down selection result; The result of the action is adjusted in request LDM module prediction load; Carry out load adjustment action or send fill order to the external loading adjusting module;

The LDM module is predicted its load adjustment the result of the action and will be predicted the outcome and returns the LDR module; The monitoring load index is sent the Load Reshuffling request to the LDR module when loading index does not satisfy.

The LDR module can be divided into decision-making part and operating part.Decision-making part is selected required a series of actions of carrying out for to reach the load target that external request will reach, and LDM then provides the prediction (predict that each moves the influence that may cause the overall system load) of the result of the action in this selection course.In case action sequence is selected, then gives operating part, calls modules such as outside DCCC, CHS, HO again by operating part and really finish required various operations.

LCC module, AC module, LDM module are sent the Load Reshuffling request to the LDR module when loading index does not satisfy.

Modules such as DCCC, CHS, HO are carried out actual load adjustment operation for the LDR module, really reach the purpose of adjusting load level and flexible allocation resource by means such as dynamic adjustment channel width, switching channels type, execution load switchings.Concrete, the effect of DCCC is a speed of adjusting wireless transmission channel dynamically; The effect of CHS is to select different transmission channel kinds (dedicated channel or common signal channel etc.) for the user; The effect of HO is that the user is switched in different sub-districts, also can enjoy continuous service to guarantee this user in moving.

To sum up, externally under the triggering of condition (for example LCC, AC, LDM), dynamically adjust, reduce or recovery load level, dynamically adjust the resource allocation tendency, to reach the purpose that improves power system capacity and keep the stability of a system for system load.Notice that the work that LDR did is not only the reduction load, also be included in load and make full use of resource when light, to avoid occurring the situation that user quality only can continuous decline can not be gone up.The location of LDR module only is the reformation for load among the present invention, does not relate to the judgement for resource-constrained state.Popular says, determine when to do, accomplish which kind of degree by other modules, and LDR only is responsible for how do i, the cancellation internal trigger benefit be exactly make the call relation of functional module clearer and more definite, clear, moreover for when doing and accomplish the judgement of which kind of degree, LDM, LCC and AC module are all more had a say.

With the said system is applied environment, and the Load Reshuffling method comprises the following steps:

The S1.LDR module receives the Load Reshuffling request, comprises the currency and the desired value of loading index in the described outside reformation request message;

The S2.LDR module is selected load adjustment action and is adjusted the user and write down selection result;

S3.LDR module request load monitoring module is adjusted the result of the action to selected load and is predicted;

S4.LDM module prediction load is adjusted the result of the action and will be predicted the outcome and returns the LDR module; The LDM module judges whether this result satisfies the desired value of described loading index, if continue step S5; If not, return step S2;

The S5.LDR module is carried out load adjustment action or is sent fill order.

The LDR module is divided into decision-making part and operating part.Decision-making part is selected required a series of actions of carrying out for to reach the load target that external request will reach, and LDM then provides the prediction (predict that each moves the influence that may cause the overall system load) of the result of the action in this selection course.In case action sequence is selected, then gives operating part, calls modules such as outside DCCC, CHS, HO again by operating part and really finish required various operations.Function executing part is fairly simple, carries out just passable successively according to the resulting action lists of decision-making part exactly.

Trigger the external loading of LDR module and reform request respectively from LCC, AC, LDM module, the required necessary information that provides is when sending the Load Reshuffling request to LDR:

1, loading index.At present with five indexs, the ascending load factor, the down load factor, descending sign indicating number resource, the Credits of NodeB (base station), the terrestrial transmission bandwidth (can comprise Iub interface, the Uu interface, Iub interface etc.), this loading index comprises currency and two desired values of desired value.

(1) loading index currency: external module need provide currency, and then LDR just can reduce the single stepping to the LDM inquiry.That is: the LDR module mode that obtains current index has two: one for by LCC, AC, direct notice LDR module when the LDM module triggers; Two for the LDR module be triggered the back inquire about to LDM.Preferred mode is the former, and LDR can directly obtain from the request of reforming; The latter need be to LDM module inquiry, and many operations if the inquiry amount is big, might cause message storm or interface congestion.

(2) loading index desired value: external module need provide the desired value of Load Reshuffling, and this desired value is set according to the current needs of each module.For example the AC module is received a service request, this request is if the words that insert can make down load rise 7%, and present load is 65%, and the access thresholding is 70%, then the desired value of Load Reshuffling is reduced to 63% with down load exactly, can allow this user to tap into like this.

2, Qing Qiu source: external module need be signed and be shown the source of the request of reformation.Can define for the reformation request of separate sources in the decision-making of LDR part and to give different action authorities.

3, RAB priority threshold (optional): this part information spinner will use for AC, and the new RAB of application access itself has the RAB priority attribute, this can be made as the RAB priority threshold, and AC indicates LDR only to adjust the low user of priority ratio thresholding by it.

4, whether allow to seize (optional):, therefore need external module when sending request, to confirm whether allow to seize because the influence that RAB seizes is bigger.Have only when this external module has at LDR and carry out the authority of seizing, this cell is set simultaneously is " allowing to seize ", LDR just can really implement to seize action where necessary.

For system load being adjusted to required level, LDR has many actions (Action) to select, and these actions are described as follows from low to high according to its combined influence to QoS of customer:

1, load is switched: switch the user to the different frequency/different system of low load with in covering neighbor cell or the adjacent different frequency/different system macrocell (overlay area comprises the current area overlay area).Selecting a part of user to switch to the relatively low different frequency/different system of load in this sub-district goes with covering in neighbor cell or the adjacent different frequency/different system macrocell (overlay area comprises the current area overlay area).This action can be effectively and is reduced the load level fast, and quality of services for users can not descend.Up-downgoing all is suitable for, and is mainly used in to reduce the load level.

2, real time business speed is adjusted: adjust real time business speed.For real time business, the branch that request rate and assurance speed are arranged in the RAB parameter, if the message transmission rate that therefore real time business obtained guarantees speed greater than it, actual speed rate that should business can be reduced to assurance speed, thereby obtain the reduction of load.When load is low, the actual speed rate of real time business can be heightened request rate.This Action Selection scope is less, and the load level that can reduce is also limited, and is little for the quality of service impacts of active user.Up-downgoing all is suitable for, and can be used for raising or reducing the load level.

3, the BE service rate is adjusted: adjust BE (Best Effort, non-real-time service) service rate.For BE is professional (for example FTP, Email and web page browsing), the variation of real time rate can not cause very big influence.Because the large-data operation in the BE business is bigger for the system load influence, therefore this action also can effectively be adjusted the load level, and its cost is that the BE quality of services for users can change thereupon.Up-downgoing all is suitable for, and can be used for raising or reducing the load level.

4, the BE traffic channel types is switched: shift DCH (Dedicated Channel, dedicated channel) channel user to the CCH channel transmission data.For DCH user, even this user does not have transfer of data will take yard resource and cell downlink transmitting power yet, CCH (Common Channel, common signal channel) then is a multiple users share, and the user only just takies yard resource and cell downlink transmitting power when needs transmission data; Therefore can consider that the certain user is transferred to CCH from DCH carries out transfer of data, to improve resource utilization.The load level that this action can reduce is limited, but little for the influence of BE quality of services for users.Note, this action generally comes the BE service rate and carries out after reducing, and is because the CCH data rate is less, possibly can't not switch to CCH and gets on if do not reduce the BE service rate, if system has realized DSCH, the priority of this action can be provided with to such an extent that adjust height than BE service rate.Up-downgoing all is suitable for, and only is used to reduce the load level.

5, public channel power adjustment: reduce the power that common signal channel is reserved.RNC can reserve a part of resource to common signal channel, if system has realized DSCH, the reservation power of DSCH will occupy bigger proportion.By reducing the power that common signal channel is reserved, system also can reduce down load, but for not effect of ascending load, and this action can impact per family for the usefulness of all common signal channels, and the negative effect of this action can't neglect under heavy duty situation.Only be applicable to descendingly, can be used for reducing or rising load level.

6, RAB seizes: discharge the user that permission is seized according to RAB (Radio Access Bearer, the priority attribute of wireless traffic carrying) priority.This is the last selection that reduces request for load, when above action does not all reach expected effect, just has only to allow the user who is seized directly to discharge those.This action has the greatest impact for quality of services for users, but its effect that reduces the load level is but got instant result.Be applicable to up-downgoing, only be used to reduce the load level.

The decision-making part of LDR module can define for the reformation request of separate sources gives different action authorities.The configuration of this authority does not have certain restriction, can carry out different qualifications according to different configurations.Example is as shown in table 1, can carry out 6 kinds of all actions for the request of LCC, does not then carry out the authority that RAB seizes for the request of LDM.

Table 1 LDR moves authority

The LDR module needs calling module after determining load adjustment action according to the action authority: LDM,

DCCC, CHS, HO specifically carry out.Its main call relation is:

(1), load is switched: call the HO module and carry out.

(2), real time business speed is adjusted: call the DCCC module and carry out.

(3), the BE service rate is adjusted: call the DCCC module and carry out.

(4), the BE traffic channel types is switched: call the CHS module and carry out.

(5), public channel power adjustment: can innerly realize, perhaps call the DSCH scheduler module and finish.

(6), RAB seizes: the inner realization.

LDM, DCCC, CHS, HO specifically carry out the order of load adjustment action can comply with different configuration settings.Preferably, the LDR module is sent fill order at different Load Reshuffling requests according to following execution sequence:

1, request reduces load:

(1) descending: load switching → real time business speed adjustment → BE service rate adjustment → BE traffic channel types switching → public channel power adjustment → RAB seizes.

(2) up: load switching → real time business speed adjustment → BE service rate adjustment → BE traffic channel types switching → RAB seizes.

2, request rising load:

(1) descending: public channel power adjustment → BE service rate adjustment → real time business speed adjustment → BE traffic channel types is switched.

(2) up: BE service rate adjustment → real time business speed adjustment → BE traffic channel types is switched.

When the LDR module was selected to adjust the user, if the Load Reshuffling request requires to reduce load, the LDR module was searched for from low to high according to RAB priority; Otherwise the LDR module is searched for from high to low according to RAB priority.When carrying out every kind of action,, preferentially carry out the low user's of RAB priority action when reducing load, the preferential action of carrying out the high user of RAB priority during the rising load according to the RAB prioritization of each service-user.

According to the description of agreement TS25.410 5.2.4 joint, the priority of RAB is to be determined according to user profile and QoS (Quality of Service, operation quality requirement) information etc. by CN (CoreNetwork, core net).CN sets up or revises the priority level that must indicate this RAB in the request, robs cutting capacity and queuing behavior at RAB, but the concrete execution that queuing and resource are grabbed then is to be finished by UTRAN (UMTS Terrestrial Radio Access Network UMTS land wireless telecommunications net).

As shown in table 2, issue RNC (RadioNetwork Controller according to agreement TS25.413 9.2.1.3 joint for CN, the explanation of RAB ASSIGNMENT REQUEST signaling radio network controller) will be carried Allocation/Retention Priority cell in this signaling.If RNC does not receive this part cell, illustrate that this RAB can't seize other users, but allow to be seized by other users.

Cell/packet name	Span	Implication
Cell/packet name	Span	Implication	Distribution/maintenance priority Allocation/Retention Priority		A packet name in the signaling

Table 2 RAB priority cell

Whether as can be seen from the above table, a RAB not only can be endowed 14 grades priority definition, whether can seize other users but also can be illustrated, can be seized by other users.

In system, can queuing and the judgement that seize can be placed on AC and realize that the actual execution of seizing then can be placed on LDR and finish.Specifically, to be exactly AC check after receiving the RAB request wherein RAB precedence information, if find current resource-constrainedly, this new RAB can seize other users again simultaneously, then AC sends the Load Reshuffling request to LDR, and explanation allows to seize operation in request simultaneously.If then LDR finds that other approach can't reduce load, will discharge the RAB that can be seized by other users, realize the execution of seizing.In other actions of LDR (for example BE service rate adjustment, channel type switching etc.), then complete 14 grades of priority definition according to RAB sort and carry out.

When the Load Reshuffling request was sent by the AC module, this request comprised the RAB priority threshold, and the LDR module selects low priority user to regulate according to it, and described RAB priority threshold is the priority attribute of the new RAB of application access.

Specify the LDR module with an embodiment below and how to select Load Reshuffling action and user, after decision-making part was received Load Reshuffling request from other modules, the action that will be about to carry out to LDR according to the content of concrete request was made a strategic decision and is selected the user.As shown in table 3, all can compare after each assessment is finished in the 4th～9 step with the Load Reshuffling desired value, just finish assessment in advance if reach target, directly entered for the 10th step.In the assessment in the 6th step,, can carry out segmentation, for each section determined the minimum speed limit grade that can be reduced at different priority in order to embody the difference between the RAB priority.RAB priority is that 1～6 o'clock minimum speed limit is 32kbps in this example, and minimum speed limit was 16kbps in 7～11 o'clock, and minimum speed limit was 8kbps in 12～15 o'clock.

The function of table 3 decision-making part

Table 3 has provided when the flow process of Load Reshuffling request when being descending reduction load, if Load Reshuffling request difference, the 4th～9 step was different.In the assessment in each step,, then search for from low to high according to RAB priority if require load to reduce.If require load rise, then search for from high to low according to RAB priority.If require the request of rising load, when carrying out BE service rate adjustment assessment,, only heighten grade, for example a 8kbps → 16kbps from high to low successively by its RAB priority at each RAB, 32kbps can not be transferred to quickly, so just most user can be taken into account.If carry out the public channel power adjustment, then also be only to adjust a grade at every turn.

Below only be an implementation example, in actual applications according to different configurations, this selection course is different.
