Description

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and related device for upgrading a network slice service.

Background

Network slicing is an end-to-end logical private network that provides specific network capabilities. Different network slice service requirements correspond to different levels of network latency, rate, isolation, reliability, security, etc., and operators may implement service level agreement (SERVICE LEVEL AGREEMENT, SLA) guarantees based on different combinations and differentiated service configurations of physical or virtual resources in network slice subnetwork instances (Network Slice Subnet Instance, NSSI) of the radio, carrier and core networks, e.g., providing users with service modes of different network isolation characteristics such as end-to-end slice sharing, core network user plane sharing, etc.

In order to implement management of Network slices, management functions of Network slices, such as Communication Service Management Function (CSMF) of SERVICE MANAGEMENT Function, network SLICE MANAGEMENT Function (NSMF) and Network slice subnet management Function (Network Slice Subnet Management Function, NSSMF), are newly added to the new generation mobile Network.

In the related art, network slice service upgrade is implemented through a service change process actively initiated by CSMF, for example, CSMF receives network slice service requirements of upgrade change filled manually, including service scenario, customer information, service requirement, and the like, and sends the network slice service requirements to NSMF for network Resource investigation, NSMF interacts with Resource management system (Resource MANAGEMENT SYSTEM, RMS) to confirm Resource satisfaction, when Resource investigation result is satisfied, CSMF initiates a network slice service change request to NSMF, and NSMF completes the change of network slice service together based on the changed service requirements by interacting with NSSMF, RMS and virtualized Resource arrangement system (MANAGEMENT AND Orchestration, MANO).

However, the process of manually filling out the service change requirement is time-consuming, resulting in lower efficiency of network slice service upgrade change.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 1, fig. 1 is a flowchart of a network slice service upgrade method provided by an embodiment of the present invention, applied to a network slice management function NSMF, as shown in fig. 1, the method includes the following steps:

And step 101, receiving a service upgrade intention index sent by a communication service management function CSMF, wherein the service upgrade intention index is used for indicating the service upgrade intention strength of a user on an opened network slice service.

The value range of the service upgrade intention index can be between 0 and 1, and the larger the index value is, the stronger the intention of a user to upgrade the service is, particularly, when 0 is taken, the intention of the user is not upgraded, and when 1 is taken, the intention of the user is upgraded to the highest service level.

In an actual application scenario, the CSMF may be a network device facing an operator, and the operator may input, on a CSMF user interface, a service upgrade intention index confirmed with the user according to a service upgrade requirement of the user, and the CSMF may send the service upgrade intention index to the NSMF, so that the NSMF receives the service upgrade intention index sent by the CSMF.

In one embodiment, the service upgrade intention index may be a service upgrade intention index for indicating strength of service upgrade intention, which is input on a CSMF user interface according to user intention when a network slice service is opened for a user. The method only needs to input the service requirement once on the CSMF when the service is opened, and the efficiency of service upgrading and changing can be obviously improved.

That is, the step 101 may include: and receiving a service opening request carrying the service upgrade intention index sent by the CSMF, and opening the network slice service according to the service opening request.

When the network slicing service is transacted, the CSMF user interface is used for inputting service opening information and simultaneously inputting a service upgrading intention index confirmed by a user, and the service upgrading intention index is used for guiding the NSMF to upgrade the network slicing service for the user according to the user upgrading intention intensity without triggering service upgrading change by manually filling service upgrading requirements, wherein the service opening information can comprise service scenes (such as an upgraded service package), user information, service requirements and the like. After receiving the service upgrade intention index and the service opening information, the CSMF can generate a corresponding service opening request and send the service opening request to the NSMF.

The NSMF can open the network slicing service for the user based on the service opening request, and upgrade and change the network slicing service according to the service upgrade intention index after the network slicing service is opened. As shown in fig. 2, a specific service opening procedure may be: the NSMF records the service requirement in the service opening request, converts the service requirement into a network slicing related requirement, wherein a clear mapping relation exists between the service requirement and the network slicing requirement, and can also carry out domain-by-domain disassembly on the converted network slicing related requirement to obtain the network slicing requirement of each subdomain of a wireless network, a bearing network and a core network, and then respectively interact with a network slicing subnet management function NSSMF, a resource management system RMS and a virtualized resource arrangement system MANO of each subdomain to jointly complete the deployment and service configuration issuing of an end-to-end network slicing instance, and can send a message of successful service opening to the CSMF under the condition that the service opening is successful so as to inform the CSMF that the network slicing service opening is successful.

It should be noted that, before the network slicing service is opened, the service opening investigation may be advanced to determine whether there are currently available network slicing resources, as shown in fig. 2, and the CSMF, the NSMF and the RMS may interactively complete the network resource investigation before the network slicing service is opened.

In another embodiment, the service upgrade intention index may be a service upgrade intention index input on a CSMF user interface when the user has an upgrade requirement after the user opens a network slice service. The method can flexibly meet the service upgrading requirement of the user at any time, and can support the user to change the service upgrading intention index.

That is, the step 101 may include: and after the network slice service is opened, receiving the service upgrade intention index sent by the CSMF.

I.e. after the network slice service is opened, at the moment when any user has the service upgrade requirement, entering the CSMF user interface to input the service upgrade intention index for indicating the strength of the user service upgrade intention, the CSMF may send the traffic upgrade intention index to the NSMF, which autonomously upgrades network slice traffic for the user based on the received traffic upgrade intention index without triggering traffic upgrade changes by manually filling in traffic upgrade requirements.

Step 102, determining a target business requirement parameter value matched with the business upgrading intention index.

In the embodiment of the invention, the NSMF can actively upgrade and change the network slice service opened by the user based on the service upgrade intention index, specifically, can determine the target service requirement parameter value matched with the service upgrade intention index, and then upgrade and change the network slice service according to the target service requirement parameter value.

The determining of the target service requirement parameter value may have multiple manners, for example, different service upgrade intention indexes may correspond to service requirement parameter values of different service classes, so that the target service requirement parameter value corresponding to the service class may be determined according to the received service upgrade intention index, or the service upgrade intention index may be an upgrade amplitude representing a network slice service expected by a user, so that the upgrade amplitude may be calculated as a target service requirement parameter value about the service upgrade intention index according to the service upgrade intention index, or may be a target service requirement parameter value with a calculated upgrade amplitude close to the service upgrade intention index and having available network resources.

In this embodiment, a service requirement parameter value, that is, the first service requirement parameter value, whose upgrade amplitude matches the service upgrade intention index may be calculated according to the service upgrade intention index, where the upgrade amplitude matches the service upgrade intention index may be that the upgrade amplitude is close to, the difference value is the smallest or the closest to, but the upgrade amplitude does not exceed the service upgrade intention index, and the corresponding matching rule may be specifically set according to actual needs.

In an alternative embodiment, the calculating the first traffic demand parameter value with the upgrade amplitude matching the traffic upgrade intention index includes: and calculating a first business requirement parameter value with the minimum difference between the upgrading amplitude and the business upgrading intention index. That is, the service demand parameter value having the smallest difference between the upgrade amplitude and the service upgrade intention index, that is, the closest service demand parameter value, may be determined therefrom by adjusting the service parameter value a plurality of times and calculating the upgrade amplitude a plurality of times.

Specifically, multiple tentative adjustments may be performed on the service parameter value of the network switching service when the network switching service is opened, and it is calculated whether the upgrade amplitude of each adjustment matches with the service upgrade intention index, and when it is determined that the upgrade amplitude of a certain adjustment matches with the service upgrade intention index, the service parameter value in the certain adjustment may be determined to be a first service parameter value meeting the requirement, and the first service parameter value may be recorded. The service parameters of the network slice service can include network delay, speed, isolation, reliability, security and the like.

Wherein, the calculating the first business requirement parameter value with the upgrade amplitude being matched with the business upgrade intention index may include:

Specifically, one, a plurality of or all of the service parameter values of the network slice service when the network slice service is opened can be increased by a certain amplitude or level, and then the upgrade amplitude of the adjusted service parameter values relative to the service parameter values when the network slice service is opened is calculated in a certain mode, for example, the adjustment amplitude of each parameter value is calculated respectively, and then the average adjustment amplitude is calculated, so that the current upgrade amplitude is obtained. And comparing whether the upgrading amplitude is matched with the service upgrading intention index, if so, not adjusting, determining the currently adjusted service parameter value as a first service requirement parameter value, otherwise, adjusting certain service parameter values of the network slice service again according to whether the current upgrading amplitude exceeds or is lower than the service upgrading intention index, and recalculated the upgrading amplitude until the upgrading amplitude is matched with the service upgrading intention index, and determining the service parameter value when matched as the first service requirement parameter value.

In this way, the first service requirement parameter value with the upgrade amplitude matched with the service upgrade intention index can be obtained by continuously carrying out upgrade adjustment and upgrade amplitude calculation on the service parameter value of the network slice service when the network slice service is opened, and the implementation mode is simple and reliable.

Of course, a certain rule may be adopted to regularly adjust the service parameter value of the network switching service when the network switching service is opened, for example, each time adjust the preset amplitude, adjust step by step, adjust a certain service parameter preferentially, and so on.

Further, the upgrading and adjusting the service parameter value of the network slice service when the network slice service is opened, so that the upgrading amplitude of the adjusted service parameter value relative to the service parameter value when the network slice service is opened is matched with the service upgrading intention index, and the method may include:

That is, when the service parameter value of the network slice service is adjusted when the network slice service is opened, the service parameter value can be adjusted to a fixed preset amplitude each time, and the preset amplitude can be a preset value range or a preset class number, for example, the rate is adjusted to 50 each time, and the isolation is adjusted to 1 class each time.

After each adjustment, the current upgrade amplitude can be calculated based on the service parameter value after the adjustment and the service parameter value when the service is started, and whether the current upgrade amplitude is matched with the service upgrade intention index is judged, if the matching is successful, the difference value between the current upgrade amplitude and the service upgrade intention index is minimum, and if the current upgrade amplitude does not exceed the service upgrade intention index, the current upgrade amplitude can be judged after each adjustment and the difference value between the current upgrade amplitude and the service upgrade intention index is recorded under the condition that the current upgrade amplitude does not exceed the service upgrade intention index until the upgrade amplitude of two adjacent adjustments is found to not exceed and exceed the service upgrade intention index respectively, so that the upgrade amplitude of the previous adjustment is matched with the service upgrade intention index can be determined, and the service parameter value after the previous adjustment can be recorded as the required first service parameter value.

Of course, under other conditions of successful matching, a similar manner may be adopted to determine a service parameter value corresponding to the upgrade amplitude matched with the service upgrade intention index, for example, when it is required to determine a service requirement parameter value with a minimum difference between the upgrade amplitude and the service upgrade intention index, a difference between the upgrade amplitude adjusted each time and the service upgrade intention index may be calculated respectively until it is found that a difference between the upgrade amplitude adjusted a certain time and the service upgrade intention index increases, so that it may be determined that the upgrade amplitude adjusted a previous time and the service upgrade intention index match, where the difference may be an absolute difference.

In this way, by performing successive adjustment and upgrade amplitude calculation on the service parameter value of the network slice service when the network slice service is opened according to the preset amplitude, the upgrade amplitude matched with the service upgrade intention index can be conveniently determined according to a relatively clear rule, and then the first service demand parameter value meeting the requirement is obtained.

converting the enumeration type parameter into a level parameter;

That is, in a more specific embodiment, the service parameters of the network slice service may be first classified into a numeric type parameter and an enumeration type parameter according to the value types, for example, parameters that may be represented by specific values for rate and network delay may be classified into numeric type parameters, and non-numeric parameters that may be represented by strong, medium, low, etc. for isolation, reliability, and security may be classified into enumeration type parameters.

The service parameter may be a service parameter of a non-strict matching type in the network slice service, where the non-strict matching type service parameter may be a service parameter of an enumeration type for some values, and the values of the non-strict matching type service parameter are not a, i.e. B, but the parameter level may be gradually increased along with the values, for example, the network capacity demand level represented by the value C is greater than the network capacity demand level represented by the value B, and the network capacity demand level represented by the value B is greater than the network capacity demand level represented by the value a.

And for the enumeration type parameter in the service parameters of the network slice service, the enumeration type parameter can be further converted into a parameter with numerical representation, for example, the enumeration type parameter can be converted into a grade parameter with different digital sizes according to the high-low grade, for example, the enumeration type parameter is converted into the grade parameter with values of 1,2 and 3 … … according to the order of the grade from low to high, and the higher the number is, the higher the matched service grade is represented.

Then, the current value type parameter value and the current grade parameter value can be updated and adjusted respectively, if the current value type parameter value can be increased by a preset value each time, the current grade parameter value is increased by one grade value, then a first change amplitude of the adjusted value type parameter value relative to the value type parameter value when the switch-on state is calculated, and a second change amplitude of the adjusted grade parameter value relative to the grade parameter value when the switch-on state is calculated, and an average change amplitude can be obtained by averaging the first change amplitude and the second change amplitude, namely, the service update amplitude corresponding to the adjustment is obtained.

By matching the calculated upgrade amplitude with the service upgrade intention index, whether the service parameter value adjusted at this time meets the requirement can be determined, under the condition that the current matching is not successful or the current matching cannot be determined temporarily, and then the processes of adjusting the parameter value, calculating the upgrade amplitude and matching the service upgrade intention index can be repeated until the matching is successful or the service parameter value meeting the requirement is found.

The method for calculating the variation amplitude of the value type parameter may be to calculate the variation amplitude of the value type parameter based on the adjusted value type parameter, the value type parameter at the time of opening, and the predetermined maximum value of the value type parameter, for example, the difference between the adjusted value type parameter and the value type parameter at the time of opening may be divided by the difference between the maximum value of the value type parameter and the value type parameter at the time of opening to obtain the variation amplitude of the value type parameter. The magnitude of the change in the rank parameter is calculated in a similar manner. In addition, the maximum value of the numerical type parameter and the maximum value of the level parameter may be predetermined, i.e. the maximum value of each parameter is known, corresponding to the highest level network capability parameter.

Assuming that n numerical value type parameters of the network slice service are provided, the number of the numerical value type parameters is a ₁,a₂…a_n respectively, m enumeration type parameters are provided, the number of the enumeration type parameters is b ₁,b₂…b_m respectively, the highest network capacity parameter value corresponding to the n numerical value type parameters is max _a1,max_a2…max_an, and the highest network capacity parameter value corresponding to the m enumeration type parameters after conversion is max _b1,max_b2…max_bn. In addition, assuming that the value of the numerical type parameter after upgrading and adjusting is a ₁′,a₂′…a_n ', and the value of the enumeration type parameter after adjusting is b ', b ₂′…b_m ', the calculation method of the variation amplitude of the numerical type parameter and the variation amplitude of the enumeration type parameter can be as follows:

The variation amplitude of the parameter a _i for any numerical type is denoted (a _i′-a_i)/(max_ai-a_i), the variation amplitude of the parameter b _i for any class is denoted (b _i′-b_i)/(max_bi-b_i), i is any number between 1 and n, the total variation amplitude of the numerical type parameter is equal to the sum of the variation amplitudes of the numerical type parameters, i.e. the total variation amplitude of the numerical type parameter The total amplitude of the enumeration type parameter may be equal to the sum of the amplitudes of the enumeration type parameters, i.e. the total amplitude of the enumeration type parameter

Then, the average variation amplitude of the n number type parameters and the m enumeration type parameters may be calculated, for example, an average variation amplitude range_average= (rang_num+rang_enum)/(m+n), or range_average= (rang_num/m+rang_enum/n)/2, where the calculated average variation amplitude range_average is between 0 and 1, and the average variation amplitude is the upgrade amplitude corresponding to the current adjustment.

In this way, the upgrade amplitude of the service parameter value after each adjustment relative to the service parameter value when the service is opened is calculated through the deviation degree between the service parameter value after adjustment and the service parameter value when the service is opened, so that the calculation result can be ensured to accurately reflect the current upgrade amplitude, and further the service upgrade result can be ensured to be more in line with the user expectations.

The implementation of this embodiment is described in detail below by way of an application example for ease of understanding:

For example, the value of the numerical value type parameter "uplink rate" is 200 and the value of "downlink rate" is 300 when the network slice service is opened; the enumeration type parameter "core subnet resource isolation" takes on a value of 1 and "transport subnet resource isolation" takes on a value of 2. The maximum value of the uplink rate is 300, the maximum value of the downlink rate is 500, the maximum value of the core subnet resource isolation is 3, and the maximum value of the transmission subnet resource isolation is 4.

Assume that after the above parameters are updated and adjusted once, the values of the parameters are as follows: an "uplink rate" value of 250 and a "downlink rate" value of 400; the enumeration type parameter "core subnet resource isolation" takes on value 2 and "transport subnet resource isolation" takes on value 3. The change Range of the numeric type parameter range_num= (250-200)/(300-200) + (400-300)/(500-300) =1, and the change Range of the enumeration type parameter range_enum= (2-1)/(3-1) + (3-2)/(4-2) =1, so that the average change Range, that is, the service upgrade Range range_average= (1+1)/4=0.5 adjusted this time.

Assuming that the user traffic upgrade intention index is 0.5, since the calculated traffic upgrade amplitude is consistent with the traffic upgrade intention index, and does not exceed 0.5, the upgrade-adjusted parameter can be valued at "uplink rate" value 250, the value 400 of the downlink rate is the value 2 of the enumeration type parameter core subnet resource isolation, and the value 3 of the transmission subnet resource isolation is the value of the change investigation service demand parameter, namely the value of the first service demand parameter.

After calculating the first service requirement parameter value with the upgrade amplitude matching the service upgrade intention index, the NSMF may further perform resource exploration to determine whether there is a network resource satisfying the first service requirement parameter value in the current RMS, specifically, may first determine a network resource corresponding to the first service requirement parameter value, then query whether there is the network resource available in the RMS, and determine that the first service requirement parameter value is a target service requirement parameter value meeting the requirement in the case of determining that there is the network resource available in the RMS.

More specifically, the NSMF may perform end-to-end Network slicing scheme design according to a Network slicing template (Network SLICE TEMPLATE, NST) based on the first service requirement parameter value, where the Network slicing scheme includes a core Network element type, number, deployment location, radio base station location, tracking area list, and Network resources such as AZ information, virtual local area Network (Virtual Local Area Network, vlan) information, and the like are transmitted. And then sending a message to the RMS to inquire whether the network resource corresponding to the current change investigation service requirement (namely the first service requirement parameter value) is met or not, namely whether the network resource is available or not, informing the NSMF network resource available results after the inquiry is finished by the RMS, wherein the NSMF network resource available results comprise the met or unsatisfied results, and recording the first service requirement parameter value as a required target service requirement parameter value if the network resource available result is met.

And under the condition that the network resource available result is unsatisfied, the RMS can also inform the NSMF of specific network resource information which is not satisfied, so that the NSMF can readjust the unsatisfied service parameter value in the first service requirement parameter value based on the unsatisfied network resource to obtain a target service requirement parameter value which can be satisfied.

That is, after the querying whether the network resources are available in the resource management system RMS, the method may further include:

After first calculating a first service demand parameter value that matches with a service upgrade intention index of a user, if no available network resource corresponding to the first service demand parameter value is found in the RMS when resource exploration is performed on the RMS, the NSMF needs to recalculate the service demand parameter value that has available network resources and has the upgrade amplitude as high as possible, specifically, the NSMF may analyze which service parameter values in the first service demand parameter value need to be downgraded and adjusted according to unavailable target network resource information returned by the RMS, including unavailable target network resources and/or network resources that can be provided, and even how much service parameter values need to be reduced to have available network resources, and may reduce the service parameter value that is not satisfied by a certain amplitude or level until a second service demand parameter value that is satisfied by the network resources is obtained on the basis of the first service demand parameter value obtained by previous calculation after analysis, and may record the second service demand parameter value as the required target service demand parameter value.

In this way, under the condition that network resources in the RMS are found to be unsatisfied after resource investigation, the service demand parameter value obtained by the previous calculation can be subjected to degradation adjustment to ensure that a proper target service demand parameter value is obtained, and further the network slicing service is successfully upgraded for the user.

And 103, upgrading and changing the network slice service according to the target service demand parameter value.

In this step, as shown in fig. 2, a specific service upgrade procedure may be: the NSMF records the target service demand parameter value, converts the target service demand parameter value into a network slice related demand, then carries out domain-wise disassembly on the converted network slice related demand to obtain network slice demands of all subdomains of a wireless network, a bearing network and a core network, and then interacts with NSSMF of all subdomains, the RMS and the MANO respectively to jointly complete the change of an end-to-end network slice instance and the service configuration issuing of update, and can send a message of successful service change to the CSMF under the condition of successful service upgrading change so as to inform the CSMF that the network slice service is successfully upgraded.

The interaction flow of each network device according to the embodiment of the present invention may be shown in fig. 2.

According to the network slice service upgrading method, a service upgrading intention index sent by a communication service management function CSMF is received, wherein the service upgrading intention index is used for indicating the strength of a user's intention to upgrade the service of an opened network slice service; determining a target business requirement parameter value matched with the business upgrading intention index; and upgrading and changing the network slice service according to the target service demand parameter value. Therefore, by receiving the service upgrade intention index sent by the CSMF, the NSMF can automatically upgrade and change the network slice service opened by the user based on the index, and the user does not need to spend more time to fill in the service change requirement, so that the service upgrade and change efficiency can be improved compared with the related technology.
