Embodiment
At existing self-optimizing network (SON, SelfOptimization Network) in the mechanism, in order to realize that the functions such as automatic configuration of the adjacent cell relations of ENB are also comprised operation management maintain (OAM in SAE system architecture as shown in Figure 1, Operations, Administration﹠amp; Maintenance) server.Because OAM server and MME Pool and SGW Pool all have annexation (as shown in Figure 3), therefore, the embodiment of the invention is utilized this OAM server, provide a kind of destination node to choose scheme, do not provided the problem that realizes concrete scheme that target MME or target SGW are selected based on information on load in the prior art to solve based on information on load.
Be explained in detail to the main realization principle of embodiment of the invention technical scheme, embodiment and to the beneficial effect that should be able to reach below in conjunction with each accompanying drawing.
As shown in Figure 4, the specific implementation flow chart of a kind of destination node choosing method based on information on load that provides for the embodiment of the invention comprises:
The information on load of each mobile management nodes that step 41, destination node selecting device receive is that the OAM server is sent, obtained by the OAM server;
Correspondingly, the embodiment of the invention provides a kind of OAM server, is applied in the System Architecture Evolution system, comprising:
Obtain the unit, be used to obtain the information on load of each mobile management nodes;
Transmitting element, the information on load that is used for obtaining the unit acquisition sends to the destination node selecting device.
In addition, the embodiment of the invention also provides a kind of destination node selecting device, is applied in the System Architecture Evolution system, comprising:
Receiving element is used to receive the information on load of each mobile management nodes that the OAM server is sent, that obtained by described OAM server;
Choose the unit, be used for information on load, choose the lightest mobile management nodes of load as destination node according to the receiving element reception.
Because the information on load of each mobile management nodes can periodically upgrade, therefore, if in adjacent two time cycles, the load that all is same mobile management nodes is the lightest, then in this two time cycles, the capital selects this mobile management nodes as destination node, will cause bigger load impact to this mobile management nodes like this, makes the stability of whole system be under some influence., in the embodiment of the invention said method is improved for this reason, another kind of destination node choosing method based on information on load is provided, the specific implementation flow chart of this method comprises as shown in Figure 5:
This method that provides according to the embodiment of the invention, be according to loading by light to heavy selection principle, select the part mobile management nodes earlier by the OAM server, the OAM server sends to the target selection node with the mobile management nodes identification information of choosing then, by the identification information of target selection node according to the mobile management nodes that receives, from the part mobile management nodes that the OAM server is chosen, select a mobile management nodes as destination node, therefore, in the process of periodically choosing destination node, just the mobile management nodes that given load is the lightest again is as destination node, thus the bigger problem of load impact that the lightest mobile management nodes of can avoiding loading is subjected to.
With the SAE system is example, when HO takes place, the MME that serves for UE need choose a SGW as target SGW from the new SGW Pool that UE will switch to, so that setting up user's face connects, according to destination node choosing method provided by the invention, the specific implementation schematic flow sheet of in the SAE system target SGW being chosen comprises as shown in Figure 6:
In above-mentioned steps 61, because each candidate SGW periodically sends the information on load of self often to the OAM server, therefore, for whether the information on load of checking the OAM server to obtain is the Payload information that candidate SGW sends in current period, candidate SGW is in transmission self information on load, also in this information on load, carry the rise time of this information on load, follow-up OAM server is after obtaining this information on load, whether the time difference by judging current time and this information on load rise time is greater than transmitting time cycle of the information on load of candidate SGW, can judge whether this information on load of receiving is effective, particularly, when judging that this time difference is not more than the transmission of information on load during the cycle, judge that this information on load is effective, otherwise, judge that then this information on load is invalid, initiate to regain the notice of information on load by the OAM server to candidate SGW.
At above-mentioned steps 62, according to the information on load that obtains, by light selection principle, select candidate SGW to constitute number up to specification successively or when meeting the best candidate SGW subclass of the indicated number of indication information according to load to weight, can but be not limited to by following dual mode:
First kind of mode, the mode of absolute magnitude indication, be the fixing numeral of SGW number regulation that comprises in the best candidate SGW subclass promptly by the OAM server, such as when this fixing numeral is 5, explanation is 5 according to the number of the SGW of the ascending selective sequential of information on load from new SGW Pool;
The second way, measure the mode of indication indirectly, promptly stipulate an indication information at the SGW number that comprises in the best candidate SGW subclass by the OAM server, such as, when the indicated value of this indication information is 1/3, the SGW number that comprises in the expression best candidate SGW subclass be among the new SGW Pool all candidate SGW sums 1/3, add up to 30 such as all candidate SGW among the new SGW Pool, then according to the indicated value 1/3 of this indication information, the SGW number that comprises in the best candidate SGW subclass corresponding with this new SGW Pool just is 10, in order to guarantee that the SGW number that comprises in the resulting best candidate SGW subclass of mode according to indirect amount indication is an integer, therefore need multiply by the resulting numerical value of this indicated value to all candidate SGW sums rounds, according to the mode that rounds that rounds up, the mode that rounds of perhaps directly giving up the decimal point aft section all can.
At above-mentioned steps 64, when MME chooses a SGW as target SGW according to the identification information of each SGW in the best candidate SGW subclass that is sent by the OAM server that receives, can but be not limited to select target SGW by following dual mode:
First kind of mode, polling mode, when adopting this mode, MME is except the identification information that receives each mobile management nodes that is sent by the OAM server, also receive the arrangement position information of the mobile management nodes that the identification information of each mobile management nodes that the OAM server sends identifies respectively, wherein, described each mobile management nodes that mobile management nodes arrangement position information is chosen for the OAM server according to load by light to the arrangement position information of heavily arranging, behind the identification information and mobile management nodes arrangement position information of each SGW in the best candidate SGW subset information that MME obtains to be sent by the OAM server, mode according to poll, according to best candidate SGW subset information, from best candidate SGW subclass, select a SGW as target SGW, such as if best candidate SGW subclass in the SGW number that comprises be 3, then in the 1st cycle, the OAM server is according to the information on load that obtains all candidate SGW, according to loading by light to heavy selection principle, select 3 SGW and constitute best candidate SGW subclass, and identification information and the arrangement position information thereof of these 3 SGW sent to MME, by identification information and the arrangement position information of MME according to 3 SGW, from these 3 SGW, choose according to load by gently to being rearranged in the 1st SGW as target SGW, and when the 2nd cycle, then equally by the information on load according to all the candidate SGWs that obtain of MME according to the transmission of OAM server, according to loading by light to heavy selection principle, the identification information of 3 SGW that select and this 3 SGW are according to loading by light to the arrangement position information of heavily arranging, choose among 3 SGW according to load by gently to being rearranged in the 2nd SGW as target SGW, by that analogy, when the 4th cycle, then select to be arranged in the 1st SGW that is as target SGW, thereby proceeding poll chooses, summary is got up, the mode of poll is exactly to obtain the remainder of the merchant of the number of SGW in the periodicity of information on load of each SGW and the best candidate SGW subclass when non-vanishing when the OAM server, in the best candidate SGW subclass that sends according to the OAM server by MME the identification information of each SGW and each SGW according to load by light arrangement position information to weight, from best candidate SGW subclass, choose according to load by gently to permutatation with remainder locational SGW of the same size as destination node, and when remainder is zero, then by MME according to best candidate SGW subset information, from best candidate SGW subclass, choose according to load by gently to permutatation in the end one SGW as destination node;
The second way, random fashion, promptly SGW of identification information picked at random of each SGW adopts Javascript (a kind of programming language) to realize that SGW of picked at random is specially as target SGW from best candidate SGW subclass as target SGW in the best candidate SGW subclass that is sent according to the OAM server by MME:
Target_Index＝Math.ceil((Math.random()*N))
Wherein, Target_Index is used for indicating target SGW at the residing arrangement position of best candidate SGW subclass.
In some specific situations, when having increased SGW newly among the new SGW Pool that need switch at UE, the load that then should newly-increased SGW has is often for the lightest, so the most suitable target SGW that is chosen for, yet, because when adopting above-mentioned random fashion to carry out choosing of target SGW, all SGW have the identical probability that is chosen for target SGW in the best candidate SGW subclass, therefore, should can not embody self the most suitable advantage that is chosen for target SGW by newly-increased SGW, for this reason, in the embodiment of the invention, be adopted as the method that newly-increased SGW gives weight factor, increased the probability that this newly-increased SGW is chosen for target SGW, the idiographic flow schematic diagram of this method comprises as shown in Figure 7:
Below in conjunction with accompanying drawing 8,9 illustrate intuitively OAM is how weight factor that the SGW that increases newly gives has increased the probability that newly-increased SGW is chosen for target SGW, as shown in Figure 8, for comprising SGW with weight factor schematic diagram in interior best candidate SGW subclass, wherein, the SGW number that comprises in the Candidate Set at all candidate SGW places is M, the SGW number that comprises in the best candidate SGW subclass is N (N≤M), D3 is newly-increased SGW, the numerical value of its weight factor is 2, D7, D5, D8 is not for being assigned with the SGW of weight factor, its default-weight factor all is 1, as shown in Figure 9, Fig. 9 comprises SGW with weight factor schematic diagram in interior equivalent best candidate SGW subclass for Fig. 8 showed, as can be seen from Figure 9, numerical value according to weight factor, newly-increased SGW D3 quilt equivalence in equivalent best candidate SGW subclass is two SGW D3 with weight factor 1, like this, when choosing target SGW from this equivalence best candidate SGW subclass, the probability that D3 is chosen for target SGW is exactly such as D7, D5,2 times of D8.Adopt Javascript to realize determining that according to the target SGW that from equivalent best candidate SGW subclass, chooses the position of this target SGW in best candidate SGW subclass is specific as follows:
The first step, in equivalent best candidate SGW subclass, determine the residing position of SGW at random:
Target_Index’＝Math.ceil((Math.random()*N’))；
＝Math.ceil((Math.random()*(N+1)))；
＝Math.ceil((Math.random()*5))；
Wherein, Target_Index ' is SGW residing position in equivalent best candidate SGW subclass.
Second step:, determine this SGW residing position in best candidate SGW subclass according to the residing position of this SGW in the equivalent best candidate SGW subclass of determining in the first step:
IF Target_Index ' IN[1.. weight factor] THEN
Target_Index＝1；
IF Target_Index ' is greater than weight factor THEN
Target_Index=Target_Index '+1-weight factor;
Give weight factor except above-mentioned for newly-increased SGW with light load, so that should have outside the bigger probability that is chosen for destination node by newly-increased SGW, can also be respectively SGW by the OAM server and give different weight factors respectively with different load, such as, the OAM server is according to the information on load of the SGW that obtains, can be the lightest SGW of the load factor 4 that assigns weight, for according to load by gently to the SGW that is rearranged in the 2nd factor 3 that assigns weight, for according to load by gently to the SGW that is rearranged in the 3rd factor 2 that assigns weight, the follow-up best candidate SGW subclass by the transmission of OAM server that is received by the MME basis is again chosen a SGW as target SGW from the best candidate SGW subclass that is made of the lighter SGW of load.This shows,, promptly can avoid load impact the lightest SGW of load according to the method that the SGW that has distributed weight factor is chosen, again can be chosen for the probability of target SGW bigger so that have the SGW of light load.
Except that aforesaid way; adopt any to the load lighter SGW carry out mark; make it to be chosen for the method that the probability of target SGW increases; all within protection scope of the present invention; in addition, be behind the load information that has obtained SGW no matter, and constitute optimum SGW candidate subset by SGW before, carry out for each SGW gives different weight factors; still constituted optimum SGW candidate subset by SGW after, carry out, also all within protection scope of the present invention.
Need to prove, because the setting of weight factor is in order to make specific SGW (as newly-increased SGW or the lighter SGW of load) attract load apace, and then the load balancing of reaching each SGW in the SGW Pool, therefore, when the OAM server judges that the load of the newly-increased SGW obtain having weight factor acquires a certain degree and when no longer being the SGW that loads the lightest, by the OAM server weight factor of this SGW is removed, maybe the weight factor with this SGW is normalized to 1, maybe the weight factor of this SGW is set to consistent with the less weight factor that has of other SGW among the SGW Pool, have bigger weight factor no longer so that this SGW compares with other SGW among the SGW Pool, so just can prevent increases the affected problem of the stability of a system that causes fast owing to the load of this SGW.
