A kind of method that realizes link audit
Technical field
The present invention relates to the resource management techniques in the communication network, be specifically related to a kind of method that realizes link audit.
Background technology
At present, base station node B can be the data format of transport layer link by the Data Format Transform of physical channel with the upward signal of user terminal (UE) emission, and will finish data converted and send to radio network controller (RNC); In like manner, Node B can also will be the data format of physical channel by the Data Format Transform of transport layer link from the data of RNC, and will finish data converted and send to UE.The data converting function that above-mentioned Node B can realize is commonly called the conversion between wireless network layer data and the transmission network layer data, and this is the important function that present Node B can realize.
Node B relates to the several functional units of self when carrying out above-mentioned data transaction: air-link resources administrative unit, wire link rm-cell, Date Conversion Unit.Wherein, air-link resources administrative unit, wire link rm-cell are respectively applied for the operations such as foundation, deletion of Radio Link, wire link among the management Node B; Date Conversion Unit then is mainly used in the data transaction of carrying out between Radio Link and the wire link.Above-mentioned air-link resources administrative unit, wire link rm-cell, Date Conversion Unit are respectively the logic entities that can realize corresponding function.
Particularly, when the air-link resources administrative unit inserts Node B at first at UE,, can transmit data wireless links to guarantee this Radio Link for UE distributes wireless transmission resources, sets up Radio Link and distribute the Radio Link sign according to the resource of distributing.Afterwards, the air-link resources administrative unit is informed the wire link rm-cell with the chain line that self distributes by RNC.The wire link rm-cell receives that Radio Link identifies the back and distributes wired transfer resource, establishes wired link and be assigned the wired link sign according to the resource of distributing for UE, can transmit the wire link data to guarantee this wire link.The described wire link sign that the described Radio Link sign that the wire link rm-cell will be received is distributed with self is set up corresponding relation and is preserved; Simultaneously, the wire link rm-cell also will exist the Radio Link sign of corresponding relation to send to Date Conversion Unit with the wire link sign.
Date Conversion Unit identifies the Radio Link of receiving and corresponding wire link sign is preserved.Afterwards, Date Conversion Unit is changed these data when receiving the data wireless links that comprises described Radio Link sign, and identifying pairing wire link sign self searching described Radio Link, the data after will changing afterwards send to the wire link that finds and identify pairing wire link.Data after the described conversion will finally be sent to RNC by this wire link.In like manner, Date Conversion Unit is changed these data when receiving the wire link data that comprise described wire link sign, and identifying pairing Radio Link sign self searching described wire link, the data after will changing afterwards send to the Radio Link that finds and identify pairing Radio Link.Data after the described conversion will finally be sent to UE by this Radio Link.Usually can think that Radio Link and wire link that air-link resources administrative unit and wire link rm-cell are set up respectively are Radio Link and the wire links that Date Conversion Unit will be applied to because of carrying out data transaction.
By the above as seen, chain line by separately between Radio Link of setting up at same UE among the Node B and the wire link has formed corresponding relation, Date Conversion Unit then is to be used for carrying out data transaction between the Radio Link that has corresponding relation and the wire link, and carries out follow-up transmission by described Radio Link or wire link to finishing data converted.Yet in actual applications, some garbles among the Node B can cause described wire link or Radio Link to be discharged unusually, cause the one-to-one relationship between Radio Link and the wire link to be destroyed.Usually also the situation that corresponding relation between this Radio Link and the wire link is destroyed can be called Radio Link and wire link is inconsistent.
In principle, for wire link that has corresponding relation and Radio Link, in case wire link wherein or Radio Link are discharged unusually, so still, undelivered another transmission link also with regard to having lost the meaning that exists because of can't independently supporting UE to communicate by letter with Node B, therefore should discharge this transmission link to save limited transfer resource among the Node B.People are attempting the whole bag of tricks always and are taking place effectively to avoid the inconsistent situation of Radio Link and wire link, as: guarantee that as far as possible air-link resources administrative unit and wire link rm-cell carry out the correctness of link processing, improve bottom transmission link reliability etc., but in actual applications, the inconsistent situation of Radio Link and wire link still happens occasionally.Therefore, in order to save the transfer resource among the Node B, link audit operation between air-link resources administrative unit and the wire link rm-cell is widely used gradually, be used to guarantee when Radio Link and wire link are inconsistent, the transmission link that wherein still keeps is discharged, to save the transfer resource among the Node B.
The link audit operation of carrying out between air-link resources administrative unit and the wire link rm-cell is generally:
The air-link resources administrative unit periodically sends to the wire link rm-cell with the Radio Link sign of self current foundation, the wire link rm-cell is according to the corresponding relation between the Radio Link sign of receiving and Radio Link sign of self preserving and the wire link sign, whether the sign of judging the wire link that self sets up exists corresponding relation respectively with the described Radio Link sign of receiving, if the wire link sign that does not have corresponding relation with described Radio Link sign is arranged, the wire link rm-cell is then deleted this sign and is discharged the corresponding wire link of this sign; Simultaneously, the wire link rm-cell also judges whether there is the Radio Link sign that does not have corresponding relation with the sign of the wire link of self setting up in the Radio Link sign of receiving, if have, the wire link rm-cell then sends to the air-link resources administrative unit with this Radio Link sign, and the Radio Link that air-link resources administrative unit and then deletion are received identifies and discharges this and identifies pairing Radio Link.
As seen, the operation of the link audit that carries out between air-link resources administrative unit and the wire link rm-cell, the transmission link that can will wherein still keep when Radio Link and wire link are inconsistent discharges, with the transfer resource among the saving Node B.But in actual applications, there are two more serious problems in aforesaid operations, one of them problem is: at the initial access of UE, Radio Link among the Node B is set up with wire link foundation sequencing, has both just set up the wire link at UE after having set up at the Radio Link of UE.If described audit operation occurs in described Radio Link and finishes and set up and described wire link unfounded moment still, the Radio Link of having set up so at UE will be released, this make UE can't with the network side proper communication, seriously reduce the reliability of UE and network side proper communication, greatly reduced user satisfaction.
Another problem is: in the network service process, because of the inconsistent probability that need carry out audit operation of link is not very high, therefore do not need to carry out continually the periodicity audit operation.Clearly, a lot of audit operation can be carried out when proper communication, these audit operation that there is no need have increased central processing unit (CPU) occupancy of Node B, make this CPU disposal ability obviously reduce, the customer service that causes needing among the NodeB to handle is affected, reduce QoS of customer, also reduced user satisfaction.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of method that realizes link audit, improves the reliability of UE and network side proper communication, reduces the CPU usage of Node B.
For achieving the above object, technical scheme of the present invention is achieved in that

Embodiment
Below in conjunction with drawings and the specific embodiments to the detailed description of the invention.
The method of realization link audit provided by the present invention is used for guaranteeing Radio Link that the base station is set up and the consistency between the wire link; Wherein, set up Radio Link, establish wired link by the wire link rm-cell by the air-link resources administrative unit; This method comprises: judge whether Radio Link and the wire link set up in the base station be corresponding one by one, and judging Radio Link and wire link not one by one at once, triggering between air-link resources administrative unit and the wire link rm-cell and carry out link audit.
Referring to Fig. 1, Fig. 1 is the link audit flow chart of a preferred embodiment of the present invention, and this flow process may further comprise the steps:
Step 101: when the air-link resources administrative unit has been set up Radio Link, and when the wire link rm-cell had been set up with the corresponding wire link of this Radio Link, Date Conversion Unit can be received from this Radio Link sign of wire link rm-cell and corresponding wire link sign thereof.At this moment, Date Conversion Unit judges whether self is corresponding one by one because of the Radio Link and the wire link that carry out data transaction and will be applied to, whether has consistency between described Radio Link and the wire link that is:.
Above-mentioned judgement totally can be used two kinds of methods and be carried out, first kind of determination methods is: set in advance a data change-over period, Date Conversion Unit judges to have in the Radio Link and wire link of corresponding relation, whether do not carried out data transaction in the cycle in data transaction at corresponding Radio Link and wire link, if illustrate that then the pairing wire link of Radio Link has been discharged probably unusually.
Yet in these cases, Date Conversion Unit can't determine immediately that described Radio Link and wire link are not corresponding one by one, because some minor errors in initial access base station of UE or the communication process also may cause the generation of above-mentioned situation, so also need to set in advance sense cycle and transcription error threshold value.The once above-mentioned situation of not carrying out data transaction of every generation, Date Conversion Unit is just determined to have taken place the data transaction mistake one time.When Date Conversion Unit established data transcription error number of times had surpassed the transcription error threshold value that is provided with in the sense cycle that is being provided with, Date Conversion Unit determined that then the Radio Link and the wire link that self will be applied to are not corresponding one by one; Otherwise Date Conversion Unit determines that described Radio Link and wire link are corresponding one by one.
Such as: the data transaction cycle is set to 10 milliseconds, and sense cycle is set to 100 milliseconds, and the transcription error threshold value is set to 5 times.When Date Conversion Unit had not carried out data transaction at corresponding Radio Link A and wire link B in 10 milliseconds, Date Conversion Unit was then determined to have taken place the data transaction mistake one time; When the described data transaction errors number at Radio Link A and wire link B had surpassed 5 times in 100 milliseconds, Date Conversion Unit determined that then the Radio Link and the wire link that self will be applied to are not corresponding one by one.
Certainly, the duration of above-mentioned sense cycle is usually greater than the duration in data transaction cycle.
Second kind of determination methods is: if Date Conversion Unit is to after finishing conversion from the data of Radio Link, this Radio Link sign that can't store according to self and the corresponding relation between the wire link sign find this wire link and identify pairing wire link, make Date Conversion Unit to send to described wire link with finishing data converted, Date Conversion Unit is then determined to have taken place the data transaction mistake one time.
Yet in these cases, Date Conversion Unit can't determine immediately that described Radio Link and wire link are not corresponding one by one, because some minor errors in the communication process also may cause the generation of above-mentioned situation, so also need to set in advance sense cycle and transcription error threshold value.Every generation is once above-mentioned can't will finish the situation that data converted sends to wire link, and Date Conversion Unit is just determined to have taken place the data transaction mistake one time.When Date Conversion Unit established data transcription error number of times had surpassed the transcription error threshold value that is provided with in the sense cycle that is being provided with, Date Conversion Unit determined that then the Radio Link and the wire link that self will be applied to are not corresponding one by one.
Such as: sense cycle is set to 100 milliseconds, and the transcription error threshold value is set to 5 times.When Date Conversion Unit to finding the wire link Y of Radio Link X correspondence after finishing conversion from the data of Radio Link X, make that Date Conversion Unit can't be when finishing data converted and send to wire link Y, Date Conversion Unit is then determined to have taken place the data transaction mistake one time; When the described data transaction errors number at Radio Link X and wire link Y had surpassed 5 times in 100 milliseconds, Date Conversion Unit determined that then the Radio Link and the wire link that self will be applied to are not corresponding one by one.
Use above-mentioned two kinds of methods when Date Conversion Unit and judge Radio Link and wire link, carry out step 102 not one by one at once; Otherwise, immediately or through returning step 101 after the time cycle, or direct process ends, no longer carry out subsequent operation.
Why Date Conversion Unit can carry out above-mentioned decision operation, be because at present Date Conversion Unit is responsible for carrying out data transaction between the wire link that Radio Link that the air-link resources administrative unit set up and wire link rm-cell set up, therefore when the situation of Radio Link and wire link inconsistency took place, Date Conversion Unit can be known this situation in time, accurately.In view of this, can be by setting operation logic in Date Conversion Unit, with guarantee that the air-link resources administrative unit has been set up a wireless links, the wire link rm-cell has been set up and the corresponding wire link of this Radio Link after, Date Conversion Unit can detect the consistency between the wire link of the Radio Link of air-link resources administrative unit foundation and the foundation of wire link rm-cell.
Step 102: Date Conversion Unit triggers between air-link resources administrative unit and the wire link rm-cell and carries out link audit.
Concrete operations are generally: Date Conversion Unit sends the link audit order to the air-link resources administrative unit, after the air-link resources administrative unit is received this link audit order, and carries out link audit between the wire link rm-cell.
It is identical to carry out the corresponding auditing method used in the method for link audit and the prior art between above-mentioned air-link resources administrative unit and the wire link rm-cell.
In actual applications, Date Conversion Unit also can send the link audit order to the wire link rm-cell, after the wire link rm-cell is received this link audit order, and carries out link audit between the air-link resources administrative unit.It is identical to carry out the corresponding auditing method used in the method for link audit and the prior art between above-mentioned wire link rm-cell and the air-link resources administrative unit, and just wire link rm-cell and the air-link resources administrative unit auditing method compared to existing technology as the audit main body carried out exchange.Certainly, also to guarantee to preserve in the air-link resources administrative unit Radio Link sign of foundation and the corresponding relation between the wire link sign.
The method of preserving described corresponding relation in the air-link resources administrative unit has multiple, such as: after the described wire link sign that the described Radio Link sign that the wire link rm-cell will be received is distributed with self is set up corresponding relation, the Radio Link sign that establishes corresponding relation is sent to the air-link resources administrative unit with the wire link sign, Radio Link sign that the preservation of air-link resources administrative unit is received and corresponding wire link sign thereof.
For another example: Date Conversion Unit is received from after the Radio Link sign that has corresponding relation of wire link rm-cell and the wire link sign, this Radio Link sign and wire link sign are sent to the air-link resources administrative unit, Radio Link sign that the preservation of air-link resources administrative unit is received and corresponding wire link sign thereof.
In step 101, Date Conversion Unit carry out described when judging at described Radio Link and wire link can be the pairing link of preserving in the Date Conversion Unit of all chain line, that is: Date Conversion Unit all Radio Links and all wire links that will be applied to.Certainly, Date Conversion Unit carry out described when judging at described Radio Link and wire link also can be current Radio Link and the wire link that does not carry out consistency detection in Date Conversion Unit all Radio Links that will be applied to and all wire links.Date Conversion Unit all is parallel processing to the consistency detection between the wire link of different radio link and correspondence thereof usually.When detecting consistency between Radio Link A and the corresponding wire link B thereof, can also detect the consistency between Radio Link X and the corresponding wire link Y thereof simultaneously as: Date Conversion Unit.
Have, the described consistency in the step 101 is judged also and can not finished the inevitable precedence relationship of existence with the foundation of described Radio Link, wire link, judges the cycle but set in advance consistency, just carries out described consistency and judge when this period expires again.Certainly, the duration in described consistency judgement cycle is greater than the duration of described sense cycle usually.
Because described air-link resources administrative unit, wire link rm-cell, Date Conversion Unit are respectively the logic entities that can realize corresponding function, so three above-mentioned unit can be separately positioned in three physical entities, also two or three unit in above-mentioned three unit can be co-located in the same physical entity.
By the above as can be seen, the method of realization link audit provided by the present invention, judge by Date Conversion Unit whether Radio Link and wire link that self will be applied to be corresponding one by one, and judging Radio Link and wire link not one by one at once, triggering between air-link resources administrative unit and the wire link rm-cell and carry out link audit.This makes air-link resources administrative unit and wire link rm-cell can not initiate audit because of the normal access of UE or garble that some are little, has obviously improved the reliability of UE and network side proper communication, and then has improved user satisfaction.
Have again, the described judgement that Date Conversion Unit carries out can guarantee that the link audit operation only just is triggered where necessary, this has obviously reduced the frequency of audit operation, and then reduced the CPU usage of Node B, help improving the ability of Node B process user business, make QoS of customer and user satisfaction to be improved.
