Fig. 3 shows a kind of possible network slice self-optimizing coordination architecture schematic diagram.Network is sliced self-optimizing and coordinates work( It can (Network Slice Self-Optimization Coordination Function；Abbreviation NS_SO_COF) it is located at In NSMF, it is responsible for coordinating the network slice self-optimizing in network, specifically at least one network slice example Multiple self-optimization functions coordinated, and/or at least one self-optimization function shared to multiple networks slice example carries out Coordinate.The function of NS_SO_COF includes at least one of the following：The self-optimizing association that network is sliced is received from operator or SvMF Adjust strategy, such as priority between NSI, the priority between self-optimization function；According to the self-optimizing coordination strategy of acquisition, with And all self-optimization function information, it calculates and is applied to the self-optimizing coordination strategy of itself, such as which self-optimization function is needed Coordinated, which Optimal Parameters etc. should be coordinated；It is interacted with self-optimization function, notifies the self-optimizing work(that may be clashed Can, so that self-optimization function is executed self-optimizing result, the forward direction NS_SO_COF of modification NSSI configurations reports optimization algorithm result；Into Row self-optimizing is coordinated, and notifies self-optimization function, if is able to carry out optimum results etc..Network is sliced subnet and optimizes function (Network Slice Subnet Self-Optimization Function；Abbreviation NSS_SO_F) it is located in NSSMF, it bears Duty carries out self-optimizing to NSSI.Illustratively, different NSS_SO_F can have a different self-optimizing purposes, such as capacity is from excellent The NSS_SO_F of change is used to be promoted the capacity of network slice subnet, loads the NSS_SO_F of self-optimizing for improving network slice The load etc. of net.Different NSS_SO_F can also be self-optimizing purpose having the same but optimisation strategy is different, such as first Capacity self-optimizing NSS_SO_F is the capacity for optimizing corresponding first NSSI according to the optimisation strategy of the first NSI, the second capacity Self-optimizing NSS_SO_F is the capacity etc. for optimizing corresponding 2nd NSSI according to the optimisation strategy of the 2nd NSI.Illustrated in Figure 3 The corresponding scene of network slice self-optimizing coordination architecture is the scene that a NSSI is shared by multiple NSI.As shown in figure 3, NSSMF Include the first NSS_SO_F (hereinafter simply referred to as " NSS_SO_F1 ") and the 2nd NSS_SO_F (hereinafter simply referred to as " NSS_SO_ F2”).The NSSI that wherein NSSMF is managed is the NSSI that multiple NSI share, and NSS_SO_F1 is share the NSSI first NSI is used to optimize the function of the NSSI；NSS_SO_F2 is to share the 2nd NSI of the NSSI to be used to optimize the function of the NSSI.Show Example property, which is shared by the first NSI and the 2nd NSI, and the first NSI is to the optimisation strategy of the NSSI with the 2nd NSI to this The optimisation strategy of NSSI is different, therefore NSS_SO_F1 may to the optimization of the NSSI to the optimization of the NSSI and NSS_SO_F2 Generate conflict, such as NSS_SO_F1 self-optimizings to the modification demand of the configuration parameter of the NSSI and NSS_SO_F2 self-optimizings to this The modification demand of the configuration parameter of NSSI is different, causes to generate conflict to the configuration of NSSI after respectively executing self-optimizing.This In the case of, NS_CO_COF is responsible for coordinating the optimization of NSS_SO_F1 and NSS_SO_F2, avoids issuable conflict.It should be understood that It includes two NSS_SO_F that Fig. 3, which schematically describes NSSMF,；In real network, a NSSMF may include at least one NSS_SO_F；Different NSS_SO_F can be the self-optimization function for belonging to a NSI, can also be the NSI for belonging to different Self-optimization function, the embodiment of the present application are not construed as limiting this.Similarly, Fig. 3 schematically describes NSMF and pass NSSMF Connection；In real network, NSMF can be associated with at least one NSSMF；Different NSSMF can be the pipe for belonging to a NSI Function is managed, can also be the management function for the NSI for belonging to different, the embodiment of the present application is not construed as limiting this.

Show that a kind of possible network slice self-optimizing provided by the embodiments of the present application is coordinated flow and shown in conjunction with Fig. 3, Fig. 4 It is intended to.Flow described in Fig. 4 can be applied to the coordination that self-optimization function is sliced to the network of multiple NSI NSSI shared, including such as Lower step：

401, NS_SO_COF obtains network and is sliced self-optimizing coordination strategy.

Optionally, NS_SO_COF receives the coordination strategy that network is sliced self-optimizing from operator, can be transported from operator Dimension personnel or a management module such as SvMF or other management modules receive.Network is sliced self-optimizing coordination strategy At least one of the following：Self-optimizing priority between NSI；When one NSI of self-optimizing, different self-optimization functions, self-optimizing The priority of parameter；Detection is needed to generate the parameter of conflict, such as NSSI capacity；There may be the different parameters of conflict, such as Self-optimizing mobility support and self-optimizing time delay etc..

402, NS_SO_COF determines the NSS_CO_F and Optimal Parameters coordinated.

NS_SO_COF determines that there may be the self-optimizings of conflict after receiving the conflict-solving strategy from operator Function and relevant parameter, such as determine that there may be punchings when NSS_SO_F1 carries out self-optimizing and NSS_SO_F2 progress self-optimizings It is prominent.

403, NS_SO_COF sends self-optimizing to NSS_SO_F and coordinates to configure message.

Wherein, the self-optimizing coordination configuration message is used to indicate NSS_SO_F before executing self-optimizing, self-optimizing Arithmetic result is reported.After i.e. instruction NSS_SO_F runs self-optimizing algorithm according to the situation of the NSSI of its self-optimizing, no Execute the self-optimizing algorithm as a result, but report the result of the self-optimizing algorithm to NS_SO_COF.

In this step, NS_SO_COF can be to multiple NSS_ of at least one of its multiple NSI managed NSSI CO_F sends self-optimizing and coordinates configuration information.

404, NSS_SO_F runs liberalization algorithm.

In this step, it receives self-optimizing in step 403 and coordinates multiple NSS_SO_F of configuration message according to it from excellent The situation of the NSSI of change runs liberalization algorithm.Specifically, the NSSI of the NSS_SO_F institutes self-optimizing is reaching NSS_SO_F certainly When optimal conditions, NSS_SO_F runs liberalization algorithm, which is used to optimize the particular characteristic of NSS_SO_F.For example, working as When the capacity of NSSI is reduced to a preset threshold value, the network slice subnet capacity self-optimization function operation for triggering the NSSI is held Measure self-optimizing algorithm.

405, NSS_SO_F reports self-optimizing arithmetic result to NS_SO_COF.

406, NS_SO_COF coordinates according to self-optimizing coordination strategy, decision self-optimizing.

In this step, NS_SO_COF judges the self-optimizing arithmetic result that multiple NSS_SO_F are reported, multiple When the optimum results of NSS_SO_F will produce conflict, the decision of self-optimizing coordination is carried out.For example, if NSS_SO_F1 in figure Self-optimizing result can and NSS_SO_F2 self-optimizing result generate conflict, and in self-optimizing coordination strategy NSS_CO_F1 from Optimize the self-optimizing priority that priority is higher than NSS_SO_F2, then the self-optimizing coordinated decision of NS_SO_COF can preferentially be allowed NSS_SO_F1 executes self-optimizing, and NSS_SO_F2 is allowed not execute self-optimizing.Or the self-optimizing coordinated decision of NS_SO_COF can be with A kind of self-optimizing that NSS_SO_F1 and NSS_SO_F2 can receive is selected as a result, realizing the compromise of the two self-optimizing result. Illustratively, NSS_SO_F1 instructions expand NSSI capacity to the 120% of current capacities in figure, and maximum size is more than current hold 200%, the NS_SO_COF that 150%, the NSS_SO_F2 instructions of amount expand NSSI capacity to current capacities can select a kind of folding In as a result, for example expanding NSSI capacity to the 150% of current capacities.

407, NS_SO_COF sends self-optimizing to NSS_SO_F and coordinates to solve message, and instruction NSS_SO_F executes self-optimizing Coordinate to solve.

In this step, the self-optimizing coordination settling mode of decision in step 406 is sent to NSS_SO_ by NS_SO_COF F coordinates to solve so that NSS_SO_F executes self-optimizing.Illustratively, if the self-optimizing result and NSS_SO_ of NSS_SO_F1 The self-optimizing result of F2 clashes and the self-optimizing priority of NSS_SO_F1 is higher than NSS_SO_F2 self-optimizing priority, then exists In the step, NS_SO_COF can indicate that NSS_SO_F1 executes its self-optimizing arithmetic result, and instruction NSS_SO_F2 does not execute it Self-optimizing arithmetic result.In another example the self-optimizing arithmetic result of NSS_SO_F1 is to expand NSSI capacity to current capacities 120%, and it is to expand NSSI capacity extremely that maximum size, which is more than the self-optimizing arithmetic result of 150%, NSS_SO_F2 of current capacities, The 200% of current capacities, then in this step, NS_SO_COF can indicate that NSS_SO_F1 and NSS_SO_F2 adjust execution Respective self-optimizing algorithm so that expand NSSI capacity to the 150% of current capacities.

408, NSS_SO_F executes self-optimizing and coordinates to solve.

In this step, NSS_SO_F coordinates to solve the instruction in message according to the self-optimizing of reception, executes self-optimizing association Conciliation is determined.Specifically, the execution which coordinates to solve may include execution self-optimizing algorithm as a result, can also include not Execute self-optimizing algorithm as a result, can also include adjustment execute self-optimizing algorithm result.Illustratively, if NSS_SO_ The self-optimizing result of F1 and the self-optimizing result of NSS_SO_F2 clash and the self-optimizing priority of NSS_SO_F1 is higher than NSS_SO_F2, then in this step, NSS_SO_F1 can execute its self-optimizing arithmetic result according to the instruction of NSS_SO_COF, The instruction that NSS_SO_F2 can thoroughly do away with NSS_SO_COF does not execute its self-optimizing arithmetic result.In another example NSS_SO_F1 from excellent It is to expand NSSI capacity to the 120% of current capacities, and maximum size is more than 150%, NSS_ of current capacities to change arithmetic result The self-optimizing arithmetic result of SO_F2 be expand NSSI capacity to the 200% of current capacities, then in this step, NSS_SO_F1 and NSS_SO_F2 can be adjusted according to the instruction of NSS_SO_COF and be executed respective self-optimizing algorithm so that expand NSSI capacity to working as The 150% of preceding capacity.

409, NSS_SO_F reports self-optimizing to coordinate result to NS_SO_COF.

A in this step, implementing result is reported to NS_SO_ by NSS_SO_F after executing self-optimizing and coordinating to solve COF.Optionally, if NSS_SO_F is not carried out its self-optimizing arithmetic result, in this step, NSS_ in a step 408 SO_F can not have to report to NS_SO_COF yet.

Optionally, after receiving the self-optimizing that NSS_SO_F is reported and coordinating result, NS_SO_COF can be to operator Self-optimizing is reported to coordinate the result solved.

Through the above steps, the embodiment of the present application can be realized when NSSI is shared by multiple NSI, the optimisation strategy of different NSI Self-optimizing when caused NSSI self-optimizings generate conflict is coordinated to solve.

Fig. 5 shows alternatively possible network slice self-optimizing coordination architecture schematic diagram, and corresponding is in a NSI Multiple NSSI between network slice self-optimizing coordinate scene.In this scenario, multiple NSSI in a NSI have respectively Network be sliced self-optimization function, on different NSSMF for optimize different NSSI multiple NSS_SO_F generate result It may influence each other, cause to optimize repeatedly, such as configuration etc. repeatedly is carried out to the parameter of NSSI.As shown in figure 5, the first NSSI First NSSMF includes (hereinafter simply referred to as " NSSMF1 ") the first NSS_SO_F (hereinafter simply referred to as " NSS_SO_F1 ")；Second The 2nd NSSMF of NSSI includes (hereinafter simply referred to as " NSSMF2 ") the 2nd NSS_SO_F (hereinafter simply referred to as " NSS_SO_F2 "). Wherein NSSMF1 manages the first NSSI, and NSSMF2 manages the 2nd NSSI；NSS_SO_F1 is that the NSI is used for the first NSSI of self-optimizing Function；NSS_SO_F2 is the function that the NSI is used for the 2nd NSSI of self-optimizing.
