(2) first network elements are according to the preferred implementation of the load information link delayed data select target network element that obtains
The embodiment of the invention has provided effective target network element choice mechanism, and preferably, the load information of each second network element that first network element obtains is specially the load state weights that obtain after the number of users normalization that each second network element has been inserted is handled; Link delayed data between each second network element that first network element obtains and different the 3rd network elements, the specifically link time-delay between each second network element and different the 3rd network elements after normalization is handled respectively, the link time-delay weights that correspondence obtains to this.After handling for above-mentioned load information and concrete link time-delay carrying out normalization; Make the time-delay of load state weights and link normalize to identical scope, therefore can obtain the weights of a total reaction target network element performance according to weights separately as normalizing to 0～1 scope.
Preferably, first network element obtains the load state weights of each second network element, specifically comprises: first network element obtains the load state weights to obtaining after the number of users normalization processing that has inserted of each second reported by network elements; Perhaps first network element carries out the normalization processing to the number of users that has inserted of each second reported by network elements, obtains the load state weights of this each second network element.Being that above-mentioned load state weights both can have been carried out by second network element and report after normalization is handled, also can be that first network element receives and obtains after number of users normalization that this second network element of second reported by network elements inserted is handled.
Preferably, first network element obtains the link time-delay weights between each second network element and different the 3rd network elements, comprising: first network element obtain each second reported by network elements to different the 3rd network elements between the link time-delay weights that obtain after handling of link time-delay normalization; Perhaps first network element carries out normalization respectively and handles the link time-delay with between different the 3rd network elements of each second reported by network elements, obtains this each second network element and the link between different the 3rd network elements weights of delaying time.Being that above-mentioned link time-delay weights both can have been carried out by second network element and report after normalization is handled, also can be that first network element receives the concrete link time-delay of second reported by network elements and carries out obtaining after normalization is handled.
Preferably,, the number of users normalization that each second network element has inserted is handled, specifically comprised: the largest user quantity that the number of users that each second network element has been inserted inserts divided by this each second network element permission no matter be first network element or second network element.
Preferably; No matter be first network element or second network element; Each second network element is handled with link time-delay carrying out the respectively normalization between different the 3rd network elements; Specifically comprise:, confirm that the link time-delay weights between this each second network element and this certain the 3rd network element are positive infinity if the time-delay of the link between this each second network element and certain the 3rd network element surpasses the setting-up time threshold value; If the time-delay of the link between this each second network element and certain the 3rd network element is no more than the setting-up time threshold value, the link time-delay with this between each second network element and this certain the 3rd network element is divided by said setting-up time threshold value.Thereby second network element that makes link time-delay surpass the setting-up time threshold value is eliminated basically and can be used as target network element, avoids occurring causing the data in the network repeatedly to retransmit, and makes the problem of network performance severe exacerbation.
Preferably; First network element is according to the load information of each second network element that obtains; And the link delayed data select target network element between this each second network element and different the 3rd network elements; Specifically comprise: sue for peace after giving weight respectively to the load state weights of each second network element and the time-delay of the link between this second network element and certain the 3rd network element weights, obtain total weight value between each second network element and certain the 3rd network element; According to the 3rd network element that carries out the target network element selection and the total weight value between all second network elements, carry out target network element and select.
Preferably, first network element weight sum that the load state weights of each second network element and the time-delay of the link between this second network element and certain the 3rd network element weights are given respectively is 1.
Therefore; Through giving weights and summation respectively to link time-delay weights and load state weights, can obtain to reflect the up-to-date link time-delay situation that reports and the total weight value of load information, total weight value is more little; The performance that this second network element is described is good more; Total weight value is big more, explains that the performance of this second network element is poor more, thereby can confirm to select which second network element as target network element.In addition, can also adjust the weight of link time-delay weights and the weight and the proportionate relationship thereof of load state weights, be to consider which factor emphatically thereby be embodied in the select target network element; For example at the network design initial stage; Customer volume is less, and the load of second network element is not under the very heavy situation, should pay the utmost attention to chain-circuit time delay; The weight of link time-delay this moment weights is greater than the weight of load state weights, thereby makes the chain-circuit time delay weight in total weight, account for larger proportion.On the contrary, in the network later stage, customer volume is bigger, then should pay the utmost attention to the load weight, and at this moment, the weight of link time-delay this moment weights is less than the weight of load state weights, thereby makes the weight of load state weights in total weight, account for larger proportion.
Preferably; First network element is according to the 3rd network element that carries out the target network element selection and the total weight value between all second network elements; Carrying out target network element selects; Specifically comprise:, choose and set quantity alternative second network element according to carrying out the 3rd network element and the size of the total weight value between all second network elements that target network element is selected; From said setting quantity alternative second network element, select one second network element at random as target network element.
Preferably; Above-mentioned setting quantity is not less than 2; If it is too big for fear of cycle T doing like this; The 3rd network element is all introduced some second network elements can impact to this second network element, thereby the load of this second network element is worsened rapidly within a short period of time, causes the serious unbalance situation of load in the network element shared pool.
(3) the advantageous applications scene of said method of the present invention
The application scenarios one of said method of the present invention does, first network element be simultaneously with the network entity of second network element and the 3rd net element communication, second network element is Mobility Management Entity MME, the 3rd network element is an evolution base station eNB.As shown in Figure 4; In the SAE system architecture; Between the MME among MME Pool and the eNBs of its covering is the annexation of multi-to-multi, and corresponding connecting interface is S1-MME (S1 Interface forMobility Management Entity, MME connect a S1 chain of command interface) interface; And also be that multi-to-multi connects between a plurality of MME among the MME Pool, its connecting interface is the S10 interface.According to the method for the invention, between eNB and MME, taken out one first network element (logical ne entity)-load-balanced server (LBS, Load Balancing Server), the corresponding LBS of MME Pool.
Under this application scenarios; First network element need to confirm the target network element that selection is communicated by letter with eNB in MME Pool; Specifically comprise: when receiving the attach request that eNB that user equipment (UE) adheres to sends, need to confirm in MME Pool, to select the MME that communicates by letter with eNB that UE adheres to; When perhaps receiving the handoff request of sending with the source MME that communicate by letter before UE switches, need to confirm in MME Pool, to select with the UE switching after the MME that communicates by letter of affiliated eNB.The attaching process that both can use UE also can be applied to the switching HO process of UE.
Preferably, above-mentioned first network element for simultaneously with MME Pool in the eNB that covers of MME and the MME Pool dns server of communicating by letter.
The application scenarios two of said method of the present invention does, first network element be simultaneously with the network entity of second network element and the 3rd net element communication, second network element is gateway SGW, the 3rd network element is MME.According to Fig. 1, a plurality of SGW and a plurality of MME among the MME Pool among the SGW Pool are annexations of multi-to-multi.Interface between MME and the SGW is the S11 interface.
Preferably, first network element confirm to need in SGW Pool, to select the target network element with MME, specifically comprises: when receiving the attach request that MME that user equipment (UE) adheres to sends, need to confirm in SGW Pool, to select the SGW that communicates by letter with MME that UE adheres to; When perhaps receiving the handoff request of sending with the source SGW that communicate by letter before UE switches, need to confirm in SGW Pool, to select with the UE switching after the SGW that communicates by letter of affiliated MME.The attaching process that both can use UE also can be applied to the switching HO process of UE.
Preferably, above-mentioned first network element for simultaneously with SGW Pool in the MME that covers of SGW and the SGW Pooll dns server of communicating by letter.
Be example with application scenarios one below, suppose that first network element is load-balanced server LBS, provides the preferred embodiment of select target network element of the present invention.
Suppose that LBS carries out the cycle that load balancing and chain-circuit time delay upgrade and is T, as shown in Figure 5, this method specifically may further comprise the steps:
Step S501, the preceding T in the T of one-period
TestIn time, all eNB in the MME Pool coverage send one to each MME of its connection and have the first information bag that transmitting time is stabbed.
Preferably, all eNB send first information bag simultaneously, and also can there be slight error in the moment of sending first information bag certainly, but concerning each eNB, are that interval T is sent first information bag.
Step S502, MME are when receiving the first information bag of certain eNB transmission, and the transmitting time stamp that carries according to first information bag just can calculate the chain-circuit time delay between this MME and this certain eNB;
Step S503, MME is according to self current number of users computational load situation weights that inserted;
Make u
iI MME allows the largest user of access to insert number, u among the expression MME Pool
i(r) i number of users that MME has inserted r cycle of expression.I the load state weights ρ of MME in r cycle among the MME Pool then
i(r) be:
ρ
i(r)＝u
i(r)/u
i。
Step S504, MME is according to chain-circuit time delay between connected each eNB and load state weights ρ
i(r) generate one and have second packets of information that transmitting time is stabbed, and the T in cycle T
TestConstantly send to LBS.
Step S505, time-delay of the second packet update link and load state weights that LBS sends according to the MME that receives.
When LBS receives above-mentioned second packets of information, need judge whether this second packets of information is an expired packet.Concrete grammar is: LBS stabs according to the transmitting time that second packets of information that receives is carried, and can calculate this second packets of information and send to the used propagation delay time t of LBS from MME, and set the time delay thresholding T of a maximum in the network
ReportIf, t＞T
Report, then this second packets of information of decidable is an expired packets of information.At this moment, LBS should initiate an active inquiry flow process, so that obtain up-to-date second packets of information that corresponding MME generates.If t≤T
Report, think that then this second packets of information is effective, at this moment, LBS just can obtain load state and the chain-circuit time delay of corresponding MME through resolving data in this second packets of information.
Present embodiment use for twice transmitting time stab measure between eNB and the MME respectively, the chain-circuit time delay between MME and the LBS; Wherein the chain-circuit time delay between eNB and the MME will be as a reference factor of target MME node selection; And whether the chain-circuit time delay between MME and the LBS mainly is expired in order to judge the packets of information that receives, and can grasp the last state of network to guarantee LBS.Can know according to top description: cycle T=T
Test+ T
Report
Step S506, LBS confirm need be in MME Pool during select target MME, based on up-to-date link time-delay and load state weights select target MME.
LBS confirm need be in MME Pool select target MME, specifically comprise following two kinds of situation:
When LBS receives the attach request that eNB that user equipment (UE) adheres to sends, need to confirm in MMEPool, to select the MME that communicates by letter with eNB that UE adheres to; Perhaps
When receiving the handoff request of sending with the source MME that communicate by letter before UE switches, need to confirm in MMEPool, to select with the UE switching after the MME that communicates by letter of affiliated eNB.
After LBS second packets of information that all MME report in receiving corresponding MME Pool, through resolving these second packets of information, just can obtain all MME the load state weights, and each MME and each eNB between chain-circuit time delay.LBS can form a table with these data, and is as shown in table 1:
Link time-delay and load state weights that table 1LBS is resolved to
Present embodiment adopts following mechanism based on chain-circuit time delay and load state weights select target MME, and is as shown in Figure 6, comprising:
Step S601, LBS carries out the normalizing processing to eNB and the chain-circuit time delay between the MME that parses, and obtains every link link corresponding time-delay weights;
With the link between eNB and the MME with L (eNB MME) identifies, as: the link between eNB1 and the MME3 is designated L (1,3).T (eNB, MME) expression link L (eNB, time delay MME).The normalizing of chain-circuit time delay is handled and can be undertaken by following principle:, set a time delay threshold value t at first according to the network concrete condition
MaxFor example, in the LTE network, the maximum transmitted time delay between regulation eNB and the MME can not surpass 100ms, then can set t
Max=50ms.If certain bar chain-circuit time delay is greater than t
Max, think that then this link can not provide a favorable service for the user, compose infinitely-great weights therefore for this link.For the time delay link less than t
MaxLink, with the actual time delay t of its link (eNB, MME) and t
MaxRatio as the link of this link time-delay weights.Through this step, for link L (eNB, MME) given a weights η (eNB, MME):
Step S602, LBS sue for peace after giving weight respectively to the load state weights of each MME and the time-delay of the link between this MME and certain eNB weights, obtain total weight value between each MME and certain eNB, provide the total weight value computing formula below:
μ
r(eNBi，MMEj)＝αρ
j(r)+(1-α)η
r(eNBi，MMEj)(0≤α≤1)(2)
μ wherein
r(eNBi MMEj) is illustrated in the total weight value between the eNBi and MMEj in r cycle, ρ
i(r)=u
i(r)/u
iBe i among the MME Pool weights, η at the load state in r cycle
r(α is the weight proportion coefficient, is used for regulating the ratio between chain-circuit time delay weight and the MME load weight according to the various network situation for eNBi, MMEj) the link time-delay weights between r interior eNBi of cycle of expression and the MMEj.For example: at the network design initial stage, customer volume is less, and the load of MME is not under the very heavy situation, should pay the utmost attention to chain-circuit time delay, and this moment, α should be less than 0.5, thereby made the chain-circuit time delay weight in total weight value, account for larger proportion.On the contrary, in the network later stage, customer volume is bigger, then should pay the utmost attention to the load weight, and at this moment, α should be greater than 0.5, thereby makes the load weight in total weight value, account for larger proportion.In addition, in some extreme scenes, α also can be used to regulate the ratio between chain-circuit time delay weights and the load state weights.For example, if the chain-circuit time delay between certain eNB and each MME always at t
MaxNear shake then should be given to α distributes a less value, makes when target MME selects, pays the utmost attention to chain-circuit time delay, can be that UE provides service to guarantee this eNB.According to formula (2), just can calculate the total weight value η between each eNB and the MME.
As input, make α=0.5, t with the data in the top table 1
Max=50ms, shown in the total weight value table 2 after LBS handles:
Total weight value between each eNB of table 2 and each MME
Step S603, LBS carries out target MME and selects according to the total weight value between all MME among eNB that carries out target MME selection and the MME Pool.
LBS is at a T in the cycle, to the ascending arrangement of total weight value η between all MME among each eNB and the MME Pool.According to the network size, select the candidate target MME collection of an optimum, and stipulate a random function random () then, the MME Random assignment in the Candidate Set is inserted to UE through random function random ().If it is too big for fear of the T cycle doing like this, the user is all introduced some MME can impact to this MME, thereby the load of this MME is worsened rapidly within a short period of time, causes the serious unbalance situation of load among the MME Pool.With table 2 data instance, the length of establishing candidate target MME is 2, and then LBS is that the candidate target MME collection selected of eNB is as shown in table 3.When certain eNB will select MME for UE, then at first inquire about LBS, LBS is according to candidate target MME collection, and using random function random () is target MME of UE Random assignment.
