Background technology
LTE (Long Term Evolution; Long Term Evolution) adopted flat architecture in the GSM; The RNC in the 3G GSM (Radio Network Controler, radio resource controller) and two network element unifications of Node B (Node B), be evolved into eNB; Omitted NBAP (Node B Application Part, the NodeB Application Part agreement) Signalling exchange between original RNC and the Node B.Access Network only comprises eNB equipment like this.ENB links to each other with core net through the S1 interface, and eNB is through Uu interface (interface between UE and UTRAN) and UE (User Equipment, subscriber equipment) communication.
In the 3G GSM; If abnormal conditions such as control board resetting appear in RNC; So after veneer re-powers, can between RNC and NodeB, carry out resource audit (the periodically process of audit is also arranged in addition), if resource is inconsistent between two network elements; Then RNC can initiate requests such as corresponding resource deletion or resource increase, to guarantee the resource alignment.That is to say, concerning RNC, if faults such as board resetting make local some resource information discharge unusually, cause RNC side resource not align, can be foundation according to the resource information that this side of NodeB exists then, rebulids resource.Fig. 1 shows the process of above-mentioned resource alignment thereof.
But above-mentioned alignment mechanism can not be used for the LTE GSM, unifies eNB equipment because RNC and NodeB have developed at the LTE GSM, can not carry out resource audit between network element in the Access Network side again.That is to say in the eNB of LTE GSM equipment, cause this locality to have resource exception to discharge, can't rely on other network elements that original resource information is provided, can only rely on the eNB device interior to address this problem if there is veneer to break down.
In the prior art, cause in the eNB equipment resource inconsistent, generally need to adopt means such as keep-alive to carry out the resource audit if veneer breaks down.Excessive for fear of the keep-alive message amount, often the time scale of keep-alive message is bigger, might reach minute level even higher, and the so long time is accomplished the also time of operate as normal needs much larger than board resetting.
Summary of the invention
The object of the present invention is to provide the method for resource alignment under a kind of eNB equipment and the abnormal conditions thereof; Be intended to solve under the LTE existing network framework; Resource appears in the eNB when inconsistent; Can't align through resource audit between network element, thereby cause the problem that eNB possibly can't normally insert even the resource extension is dead in one long period.
The present invention is achieved in that the implementation method that resource is alignd in the eNB under a kind of abnormal conditions, and said method comprises the steps:
Abnormal single-board is sent resource audit request respectively to the intrasystem related single-boards of said eNB;
Related single-boards is replied resource audit request responding information according to related resource information to abnormal single-board;
Abnormal single-board is rebuild resource according to response message.
Another object of the present invention is to provide the realization system that resource is alignd in the eNB under a kind of abnormal conditions, said system comprises:
Resource audit request generation module is used on abnormal single-board, generating resource audit solicited message;
Resource audit request respond module is used on the related single-boards of abnormal single-board, obtaining resource audit request responding information;
The resource alignment module is used on abnormal single-board, carrying out the resource alignment according to said resource audit request responding information.
The invention has the beneficial effects as follows that under some veneer abnormal conditions, said method or equipment carry out the resource alignment; It is dead to avoid resource to hang; And can make after Reset Board normally works on power, other veneers of eNB need not to reset and just can carry out normal cut-in operation rapidly, have practiced thrift unit exception recovery time largely; Avoided to pass through other board resettings or could discharge resource, thereby improved equipment dependability through long-time keep-alive.
Embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
In embodiments of the present invention, resource occurs when unusual in the eNB, and unusual veneer sends resource audit solicited message to related single-boards, replys resource audit request responding information by related single-boards, and unusual veneer is rebuild resource according to response message.Thereby realize the resource alignment in the eNB.
Fig. 2 shows under a kind of abnormal conditions that the embodiment of the invention provides the flow process of the implementation method of resource alignment in the eNB.In embodiments of the present invention, suppose that the eNB entire equipment comprises A1, A2 ..., An is n veneer altogether, works in coordination and realized the function of eNB.The resource pool of supposing eNB can be divided into R1, R2, R3 ..., Rm is the m part altogether, wherein each veneer respectively management maintenance the different resources pond.For the ease of describing, the related resource assignment information of R1 resource pool of suppose the A1 veneer maintenance, and the A1 veneer owing to fault perhaps artificial reason reset.After veneer A 1 resets, need carry out the resource alignment again, thereby trigger the following method of carrying out.
In step S201, abnormal single-board related single-boards in the eNB system is sent resource audit request;
Take place unusual veneer A 1 respectively in the eNB system related resource veneer send resource audit request.
In step S202, related single-boards is replied resource audit request responding information according to related resource information to abnormal single-board;
After relevant resource veneer is received the resource audit request information of abnormal single-board A1, read all resources relevant, and tissue sends resource audit response message to abnormal single-board A1 with abnormal single-board A1.
In step S203, abnormal single-board is rebuild resource according to the response message of replying.
Abnormal single-board A1 according to the original resource information of these these plates of response message organized renewing, accomplishes the resource alignment after the response message that collects all resource audits.
Triggering the implementation method that resource is alignd in the eNB under the execute exception situation can also be to adopt periodically verification and Event triggered verification to combine, and triggers when the needs resource is alignd in verification.
The implementation method of above-mentioned resource alignment, when the veneer resource in eNB was inconsistent, it was dead to avoid resource to hang; After making that Reset Board normally works on power; Other veneers of eNB need not to reset, and have practiced thrift the recovery time of equipment largely, need not also to need not can discharge resource through long-time keep-alive through other board resettings; The alignment of realization resource has improved equipment dependability.
Fig. 3 shows the implementation method of resource alignment under the eNB inner control veneer abnormal conditions that the preferred embodiment of the present invention provides.In the present embodiment, eNB powers on and normally starts, and normally sets up resource, and in equipment work, because fault or manual operation etc. cause controlling board resetting, the control veneer re-powers completion, and after normal the operation, need carry out the resource alignment, and concrete steps are following:
In step S301, the control veneer is related resource veneer transmission resource audit request information in the eNB system respectively.
Control veneer organizational resources audit request information, the related resource veneer sends the resource audit request information in the eNB system.
In step S302, related single-boards is sent resource audit request responding information according to related resource information to the control veneer.
The related resource veneer reads the resource relevant with controlling veneer after receiving the resource audit request information of control veneer, and according to the resource of having distributed on this plate, organizational resources audit request responding information sends to the control veneer.Not only comprise resource information in the audit of the resource here request responding information, also will comprise the relation of continuing between the resource of this plate resource and control veneer.
In step S303; The control veneer according to response message recover its resource information and with other veneers on the relationship map that continues of resource, and preserve, as the control veneer; Be the promoter of other resource veneer resource allocations; In order to ensure the resource alignment,, initiate resource release request to all the other veneers according to resource information and the veneer resource relation of continuing that last step recovery obtains;
In step S304, after other veneer resources discharged completion, the control veneer was perhaps initiated resource again according to means such as database verifications according to the information of preserving and is set up.
After other veneer resources releases were accomplished, perhaps initiate resource again according to means such as database verifications set up process to the resource information that the control veneer is preserved according to step S303, made the eNB internal resource align.
Fig. 4 shows in the eNB that the preferred embodiment of the present invention provides the flow process of the implementation method of resource alignment under the non-control veneer abnormal conditions.In the present embodiment, eNB powers on and normally starts, and normally sets up resource; In equipment work, because fault or manual operation etc. cause a non-control board B to reset, non-control veneer re-powers completion; And after the normal operation, need carry out the resource alignment, concrete steps are following.
In step S401, non-control board B organizational resources audit request information, related single-boards is sent the resource audit request information in the eNB system;
In step S402, after related single-boards is received the resource audit request information of non-control board B, read and the relevant resource of non-control board B, according to the resource of having distributed on its this plate, organizational resources audit request responding message sends to non-control board B.Not only comprise resource information in the resource audit response here, also will comprise the relation of continuing between related resource veneer resource and the non-control board B resource.
In step S403; After non-control board B collects the resource audit response message of other resource veneers; According to resource information in these response messages and the relation of continuing; Recover on this plate resource information and with other veneers on the relationship map that continues of resource, according to these information, rebulid local resource.
