Detailed ways

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

It should be understood that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Thus, appearances of "in one embodiment" or "in an embodiment" in various places throughout the specification are not necessarily referring to the same embodiment. Furthermore, the particular features, structures or characteristics may be combined in any suitable manner in one or more embodiments.

In various embodiments of the present invention, it should be understood that the sequence numbers of the following processes do not mean the order of execution, and the order of execution of each process should be determined by its functions and internal logic, rather than implementing the present invention. The implementation of the examples constitutes no limitation.

Additionally, the terms "system" and "network" are often used interchangeably herein.

In the embodiments provided in this application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined according to A. However, it should also be understood that determining B according to A does not mean determining B only according to A, and B may also be determined according to A and/or other information.

Wireless slicing supports QoS-based service assurance. The customer signs a contract with the policy control function entity (Policy Control Function, PCF), the core network is mapped to the QoS parameters and sent to the base station, and the base station is mapped to the radio bearer (Radio Bearer, RB) through the Service Data Adaptation Protocol (Service Data Adaptation Protocol, SDAP) layer , adopting a certain scheduling algorithm/parameter for RB to perform QoS guarantee. This user QoS-based solution cannot reflect the isolation of wireless slices, and users in slices are likely to be affected by other common users, so performance cannot be guaranteed.

In addition, wireless slices support service guarantee based on slice user group resource reservation. One or more slices with similar business attributes can be divided into a slice user group, and for the slice user group, the dedicated/priority/shared physical resource block (Physical Resource Block, PRB) resource ratio reserved for it can be configured. Among them, dedicated resources are only available to users in the slice user group and cannot be preempted by other slice user groups; priority resources are guaranteed to slice user group users first, and ordinary users are available when resources are left; all users of shared resources compete fairly based on QoS. Slice resource reservation can guarantee services from the dimension of frequency domain resource occupation. However, the current slicing solution cannot meet the rapid provisioning of local services, dynamic service adjustment and control requirements, and local real-time billing updates.

As shown in Figure 1, the embodiment of the present invention also provides a slice service configuration method, which is applied to network management equipment, and specifically includes the following steps:

Step 11: Acquiring demand information of the first service slice of the user equipment; wherein the demand information is determined based on the target category to which the first service slice belongs.

Optionally, the network management device may be an OMC entity or a network slice subnet management function (Network Slice Subnet Management Function, NSSMF) entity.

Optionally, the step 11 may specifically include: obtaining demand information of the first service slice of the user equipment through the local platform; wherein the demand information is: the local platform according to the first information sent by the user equipment The service requirement of the slice service is obtained after determining the target category to which the first slice service belongs. Optionally, the local platform may also provide the user equipment to determine the resource reservation ratio of the slicing service, etc., which is not limited in this embodiment of the present invention.

Wherein, the demand information refers to the network side demand determined based on the local script, which is different from the service demand of the user equipment. Optionally, the category to which the slice service belongs may include but not limited to low-latency category, high-bandwidth category, high-reliability category, etc., and the target category may be one of them.

For example: when user equipment (such as industry users) determines to add/modify services in the park, they can configure service requirements on the local platform, map the service requirements to network-side demand information through the local platform, and pass them to the OMC entity/NSSMF entity . Among them, the local platform is an interface open to industry users to configure SLA requirements, and can be deployed on local servers or base station boards in the park. The local platform includes business requirement templates, which can be divided into low-latency services, large-bandwidth services, and high-reliability services. Delay requirements can be subdivided into multiple levels of 10ms, 20ms, and 50ms. Industry users can configure/modify the business category and corresponding SLA requirements of each type of business as needed, and send the requirements to the OMC entity/NSSMF entity for parameter configuration of the service, as shown in Figure 2. In addition, industry users can also directly configure/modify the resource reservation ratio of each service on the local platform, and the corresponding service attainable rate can also be automatically generated according to typical user distribution, which is not limited in the embodiments of the present invention.

Step 12: According to the demand information, perform initial parameter configuration of the first slice service according to the target classification, and obtain initial configuration information.

Optionally, the step 12 may specifically include:

Determine the target slice of the first slice service; wherein, when adding the first slice service, the target slice is a pre-configured slice; when modifying the first slice service, the target slice It is the slice corresponding to the first slice service; according to the demand information, perform initial parameter configuration on the target slice according to the target classification.

Optionally, a default slice (that is, a pre-configured slice) can be pre-deployed on the network management device, and the pre-configured slice can be configured according to the attributes of the default slice, so that when a first slice service is added, the pre-configured Slices are used for parameter configuration. When modifying the business of the first slice, parameters can be configured based on the corresponding existing slices to ensure that industry users can quickly deploy slices without having to determine the business of the slice and the corresponding SLA requirements in advance.

For example: taking business-to-business (B2B or 2B) slices as an example, industry users sign up for an initial 2B slice, and the 2B slice can be a 2B default slice or a 2B dedicated slice (if there are other 2B businesses in the same area that are paired with businesses). For customer (Business-to-Customer, B2C or 2C) business, consider signing up for a dedicated slice; if there are only other 2C businesses, you can sign up for the default 2B slice). The 2B slice-related SLA attributes of the initial contract can be configured according to the default 2B slice attributes, so industry users do not need to determine the slice business and corresponding SLA requirements in advance, and can quickly deploy slices, realizing the dynamic adjustment of business SLA requirements during the business process. And configuration parameters, with the ability to independently control localized services, avoiding the current static contract slicing strategy that cannot meet business needs, when it is necessary to add or modify local slicing services, the process is more complicated, and it is not suitable for local rapid service deployment and dynamic adjustment. . In addition, industry users can also sign up for a total resource reservation ratio for use by all services in the park, which is not limited in the embodiments of the present invention.

Step 13: Send the requirement information and the initial configuration information to the base station.

In the above solution, the initial parameter configuration of the first slice service is performed by the network management device according to the demand information of the first slice service sent by the user equipment, since the demand information is determined based on the target category to which the first slice service belongs That is, the coarse configuration of the parameters of the first slice service is realized through the network management device, and then the initial parameter configuration of the coarse configuration is sent to the base station through the network management device, so that the base station performs service-level parameter configuration on the initial configuration information , that is to realize the fine configuration of the first slice service, thereby solving the problem that the current slice service guarantee mechanism cannot realize precise guarantee of the service.

Optionally, after sending the requirement information and the initial configuration information to the base station, the method further includes the following steps:

receiving the actual required capacity corresponding to the first slice service sent by the base station;

The initial configuration information of the first slice service is adjusted according to the actual required capacity.

Specifically, after performing service-level parameter configuration on the initial configuration information of the first slice service, the base station may, according to signal quality (such as signal-to-interference plus noise ratio (signal-to-noise and interference ratio, SINR) and other indicators) Calculate the capacity occupied by the slice group and send it to the network management device (such as OMC/NSSMF). The network management device compares this capacity with the SLA demand capacity configured by the user, and dynamically adjusts the configured slice group capacity in a closed-loop manner. For example, if the demand for business capacity increases after comparison, the resource reservation ratio can be increased; if the business capacity demand is confirmed to decrease after comparison, the resource reservation ratio can be reduced, that is, the closed-loop control of parameter configuration is realized, and business precision is further realized Assure.

As shown in Figure 3, the embodiment of the present invention also provides a slice service configuration device 300, which is applied to network management equipment, including:

An obtaining module 310, configured to obtain demand information of a first service slice of the user equipment; wherein the demand information is determined based on the target category to which the first service slice belongs;

The configuration module 320 is configured to perform initial parameter configuration of the first slice service according to the target classification according to the requirement information, and obtain initial configuration information;

A sending module 330, configured to send the requirement information and the initial configuration information to a base station.

Optionally, the first receiving module 310 includes:

The receiving unit is configured to acquire the demand information of the first slice service of the user equipment through the local platform; wherein the demand information is: the local platform determines according to the service demand of the first slice service sent by the user equipment It is obtained after the target classification to which the first slice service belongs.

Optionally, the configuration module 320 includes:

A determining unit, configured to determine a target slice of the first service slice; wherein, when adding the first service slice, the target slice is a preconfigured slice; when modifying the first service slice , the target slice is a slice corresponding to the first slice service;

A configuration unit, configured to perform initial parameter configuration on the target slice according to the target category according to the requirement information.

Optionally, the device 300 also includes:

The second receiving module is configured to receive the actual required capacity corresponding to the first slice service sent by the base station;

An adjustment module, configured to adjust the initial configuration information of the first slice service according to the actual required capacity.

The device 300 in the embodiment of the present invention corresponds to the method for configuring the slicing service on the network management device side, and it can realize each embodiment of the above method, and can achieve the same technical effect. To avoid repetition, details are not repeated here.

As shown in Figure 4, the embodiment of the present invention also provides a slice service configuration method, which is applied to a base station, and the method includes the following steps:

Step 41: Receive the requirement information and initial configuration information corresponding to the first slice service sent by the network management device.

Wherein, the requirement information is determined based on the target category to which the first slicing service belongs; the initial configuration information is that the network management device performs the first slicing according to the target category according to the requirement information The initial parameter configuration of the service is obtained.

Step 42: Perform service-level parameter configuration on the initial configuration information according to the requirement information.

In the above solution, the network management device performs initial parameter configuration of the first slice service according to the demand information of the first slice service sent by the user equipment, because the demand information is determined based on the target category to which the first slice service belongs That is, when the network management device implements the rough configuration of the parameters of the first slice service, the base station receives the initial parameter configuration of the rough configuration sent by the network management device, and performs service-level parameter configuration on the initial configuration information, that is, The fine configuration of the first slicing service is realized, thereby solving the problem that the current slicing service guarantee mechanism cannot realize accurate service guarantee.

Optionally, performing service-level parameter configuration on the initial configuration information according to the requirement information includes the following steps:

Determining a target service model corresponding to the first slice service; performing service-level parameter configuration on the initial configuration information according to the target service model according to the demand information.

Specifically, the local platform identifies the target category to which the first slice service belongs, and the base station determines the target service model corresponding to the first slice service, and the target service model belongs to the target category. For example, take the first slice service as an AI machine vision service in the high-bandwidth class as an example. After the network management device (such as OMC/NSSMF) recognizes the large-bandwidth demand of the first slice service based on the local platform, configure coarse-grained After the base station recognizes that the first slice service is the AI machine vision service model in the large bandwidth class, the base station performs refined parameter configuration and modifies the specific parameters related to the service. match.

Optionally, the determining the target service model corresponding to the first slice service includes the following steps:

Acquiring contract sending parameters corresponding to the first slice service; identifying and obtaining a target service model corresponding to the first slice service according to the contract sending parameters.

Specifically, the packet sending parameters may include, but are not limited to: packet sending size, packet sending period and other parameters. For example: the network management device (such as OMC/NSSMF) provides differentiated parameter configuration according to the SLA requirements of the first slice service, and at the same time, the base station side identifies the target service corresponding to the first slice service according to the parameters such as the packet sending size and the packet sending cycle Model. Optionally, the base station can also automatically optimize the scheduling strategy, such as adjusting the pre-scheduling period, pre-allocated resource size and other related parameters, to better match the characteristics of the service package, and realize the intelligent identification of service model perception.

Optionally, performing service-level parameter configuration on the initial configuration information according to the target service type according to the requirement information includes:

When it is determined according to the requirement information that there is a differentiated requirement for the first slice service, perform parameter configuration on the initial configuration information by using 5QI parameters according to the target service model.

For example: Based on the above example, in the case of the pre-configured 2B default slice, since the total resources of the 2B default slice may not be able to meet the requirements of each service rate, all services are uniformly compressed in resource proportions, and the re-guaranteed service may be will not be guaranteed.

In this way, the base station can perform refined service guarantee according to the parameters configured by the network management equipment (such as OMC/NSSMF). Scheduling, other services can only be used when there are resources left.

In addition, the base station can configure S-5QI level parameters, and flexibly meet different network capability requirements through different parameter configuration combinations such as pre-scheduling and scheduling request (SchedulingRequest, SR) cycle. Specialized service guarantee requirements and parameter configuration, as shown in Figure 5, the base station can adopt S-5QI-level special parameter configuration according to services with differentiated requirements to implement service-level scheduling. The differentiated parameter configuration includes but is not limited to: rate (PRB, MinBR), delay (pre-scheduling, discontinuous reception (Discontinuous Reception, DRX), etc.), reliability (target block error rate (Block Error Rate, BLER), etc. ) related parameters, so as to realize the slicing business for key guarantees and achieve differentiated guarantees.

Optionally, after receiving the demand information and initial configuration information of the first slice service sent by the network management device, the method further includes the following steps:

In a case where it is determined that a service change occurs in the first slice service, the service change information of the first slice service is sent to a charging system.

Specifically, the service change of the first slice service may include adding a first slice service or modifying a first slice service, which is not limited in this embodiment of the present application. In this way, when the base station determines that the service change of the first slice service occurs, the service change information of the first slice service is sent to the charging system to realize more real-time charging update, thus solving the current problem The slicing large network process cannot realize the real-time update of the billing system according to the local slicing service update.

Optionally, the sending the service change information of the first slice service to the billing system includes:

Sending a first message to the billing system; wherein the first message carries service change information of the first slice service, and the service change information includes at least one of the following: resource reservation related parameters, pre-scheduling Information, 5QI parameters corresponding to the first slice service.

For example: it may indicate the service change information of the first slice service through the first field in the first message, and the first field may be an RB resource data usage report (Resource Data Usage Report) field, etc., the present invention The embodiment is not limited thereto.

The resource reservation-related parameters may include but not limited to a resource reservation mode (ResourceReservation Mode), a resource reservation ratio (Resource Reservation Ratio), etc., which are not limited in this embodiment of the present invention.

Optionally, the sending the service change information of the first slice service to the billing system includes:

Sending the service change information of the first slice service to the charging system through the access and mobility management function AMF entity and the session management function SMF entity; or, sending the service change information of the first slice service It is sent to the charging system through the operation and maintenance center OMC entity, the communication service management function CSMF entity and the business operation support system.

For example: the base station counts performance indicators such as the rate, delay, and resource occupancy ratio of each service, and can report service change information to the charging system (CHF) through the following two mechanisms: One is to synchronize real-time service change information to AMF Entities (for example, the RB Resource Data Usage Report field includes the resource reservation mode (Resource Reservation Mode), resource reservation ratio (Resource Reservation Ratio), pre-scheduling information (Pre-scheduling Information) of the business and other parameter configuration related information, and synchronize the service change information to the AMF entity), and transparently transmit it to the SMF entity through the AMF entity, and the SMF entity triggers the charging function and obtains the charging from the Policy Control Function (Policy Control Function, PCF) entity The policy is finally passed to the CHF to implement billing update; the second is that the base station reports the service update information to the OMC, and the OMC transmits it to the Business Operation Support System (BOSS) through the Communication Service Management Function (CSMF), Finally, pass it to CHF to implement billing update.

Wherein, the above two charging update mechanisms can both provide periodic and event-triggered statistical updates. Periodic statistical update means that the base station periodically reports service information to the billing system, which can provide minute-level and second-level statistical granularity. Event-triggered statistical update means that the base station sets a threshold. When the difference between the reported service information of the previous cycle and the next cycle is greater than the configured threshold, an event is triggered and the current service information is reported to the billing system.

Optionally, the method also includes the following steps:

Acquire the actual required capacity corresponding to the first slice service; and send the actual required capacity to the network management device.

Specifically, after performing service-level parameter configuration on the initial configuration information of the first slice service, the base station may, according to signal quality (such as signal-to-interference plus noise ratio (signal-to-noise and interference ratio, SINR) and other indicators) Calculate the capacity occupied by the slice group, and send it to the network management device (such as OMC/NSSMF), so that the network management device adjusts the initial configuration information of the first slice service according to the actual required capacity, such as the network management device The device compares this capacity with the SLA required capacity configured by the user, and dynamically adjusts the configured slice group capacity in a closed-loop manner. For example, if the demand for business capacity increases after comparison, the resource reservation ratio can be increased; if the business capacity demand is confirmed to decrease after comparison, the resource reservation ratio can be reduced, that is, the closed-loop control of parameter configuration is realized, and business precision is further realized Assure.

The slicing service configuration system of the embodiment of the present application will be described below in conjunction with specific examples. For example, a customer in a certain industry configures local slicing for the automatic guided vehicle (Automated Guided Vehicle, AGV) service and machine vision service in the park, and the AGV service guarantee requirement Higher than the machine vision business.

User equipment subscribes to 2B default/dedicated slices and a certain resource reservation ratio. 50% of resources are reserved for 2B slices. This part of resources is dedicated or preferentially used for industry user slice services to ensure industry user service experience. When a new machine vision service is added in the park, the user equipment inputs the service source parameters, processing capacity and other parameters on the local platform, and maps out the newly added high-bandwidth service in the park through the local platform, corresponding to the 400Mbps file in the service requirement template, and sends Large bandwidth requirements are passed to OMC/NSSMF.

OMC/NSSMF configures the initial parameters to meet the high-bandwidth business parameters according to the high-bandwidth business requirements, and reserves 20% for such services and transmits them to the base station.

The base station identifies such services as machine vision through the packet size and packet interval of the user equipment, and modifies the coarse-grained parameters configured by OMC/NSSMF to meet the 400Mbps rate requirement of machine vision services.

The entire park is signed with a default slice, and 50% of PRB resources are reserved. According to the actual speed requirements of the business, it is further refined to reserve 40% for AGV cars and 20% for video backhaul. At this time, the total resources cannot meet the requirements of each service rate, and the proportion of service resources is compressed, so that the AGV of the re-insurance service cannot be guaranteed. Then, the AGV service priority is higher than that of the machine vision service through the S-5QI parameter configuration, and the AGV service is given priority. For example, Figure 9 shows.

The base station transmits information such as the reserved resource ratio, reserved resource mode, and S-5QI parameter configuration of the newly added machine vision service to the CHF through the RB Resource Data Usage Report field to complete the real-time billing system update.

OMC/NSSMF compares the occupied capacity of the AGV business and machine vision business reported by the base station with the business capacity demand of the local portal statistics, and adjusts the parameter configuration in real time to achieve closed-loop control.
