Description

Network slice information acquisition method, network slice management method and equipment

Technical Field

The invention relates to the technical field of mobile communication, in particular to a method for acquiring network slice information, a method for managing network slices and related equipment.

Background

The Service Enabler Architecture (SEAL) Layer for vertical industry is a Service Enabler Architecture Layer common to all vertical applications on 3GPP systems. It provides functions such as location management, group management, configuration management, identity management, key management and network resource management. In the related art SEAL, a Network slice capability management service (NSCM) is a new SEAL service that provides Network slice-related capability management capabilities. The services currently provided are mainly based on the control plane of the core network, providing reallocation of vertical applications to network slices (which may be defined as allocating vertical applications run by the UE to different network slices).

For a network slice used by a certain credible industry vertical user/industry platform, the industry vertical user has the requirement of network slice life cycle management for network slice creation, modification and deletion, so that the network slice management service is better provided for the industry vertical based on the interaction of a control plane and a management plane. Network slice lifecycle management services are defined in SA5 of 3GPP, including creation, deletion, modification, allocation, de-allocation operations of network slices.

In a network slice lifecycle management scheme in the prior art, a vertical industry user may directly call an interface of SA5 to implement network slice management. However, for some industry vertical users who are unaware of the 3GPP architecture and the SA5 defined network slice lifecycle management services, it is challenging to invoke the SA5 interface directly. In addition, for vertical industry users who do not know the network state, the efficiency of self-life cycle management is not efficient. In addition, the network is also not possible to open a corresponding interface for each vertical industry, so an entity and a corresponding flow scheme in the vertical industry application and the 5G network are required, a life cycle management service easy to master is provided for the vertical industry, and a safety guarantee is provided for the network.

Currently, SEAL defines a Network slice capability management service (NSCM), which can provide a simpler application layer to disclose the life cycle management of a Network slice and an additional function for a vertical industry, and the architecture of the SEAL is shown in fig. 1. The NSCM architecture can help the industry verticals do lifecycle management without knowing the interfaces and APIs defined by SA5 operation and maintenance. Including a Vertical Application Layer (VAL) and an NSCM service Layer that is a service-enabled Application Layer.

The NSCM can be regarded as an Application Function (AF), and in order to realize intelligent and automatic Application layer slice life cycle management, the embodiment of the invention provides a slice information acquisition method, which can shield complex network operation details for vertical industry users and provide support for realizing intelligent network slice life cycle management.

Referring to fig. 2, an embodiment of the present invention provides a method for acquiring slice information, which is applied to a first function, where the first function may be a network slice capability management function and/or an application function (e.g., NSCM), and the method includes:

and step 21, the first function acquires the related information of the first network slice through the second function and/or the network management system.

Here, the first function may specifically be a network slice capability management function and/or an application function. The second Function may specifically be at least one of a Network open Function (NEF), a Network Slice Admission Control Function (NSACF), and a Network data analysis Function (NWDAF).

In addition, it should be noted that the information related to the first network slice, which is obtained by the first function through the second function, may specifically be: first network slice related information provided by the second function; or the third function provides the first network slice related information. That is, the first network slice related information may be network slice information obtained by the second function from itself or another function. The third function may be at least one of NSACF and NWDAF. Here, the first network slice related information provided by the second function may be specifically derived from a network management system, that is, the second function obtains the first network slice related information from the network management system and provides the first network slice related information to the second function, and then the second function provides the first network slice related information to the first function. Specifically, the network management system may be at least one of the following systems: a network management system, a network Operation Administration Maintenance (OAM) system.

Through the above steps, the first function in the embodiment of the present invention may obtain the information related to the first network slice from one or more second functions and/or from one or more network management systems, thereby providing information support for slice lifecycle management.

Here, in step 21, the first function may obtain the first network slice related information in a request/response manner, and may also obtain the first network slice related information in a subscription/publication manner. When the request/response mode is adopted, a request is usually made once to obtain a response, and a response message carrying the relevant information of the first network slice returned by the second function and/or the network management system in response to the request is received. When the subscription/publication manner is adopted, the first network slice related information published by the related function for multiple times may be obtained through one subscription, at this time, data, an event, and an index of the subscription need to be indicated to the related function during the subscription, and a threshold (i.e., a trigger condition or a subscription condition) corresponding to the data, the event, and the index may also need to be indicated.

Specifically, the first function may send a network slice information request message to at least one second function and/or at least one network management system, and receive first network slice related information sent by the at least one second function and/or the at least one network management system;

and/or the presence of a gas in the atmosphere,

Here, the first subscription condition is set based on analysis of the first network slice-related information by the third function. In addition, the first subscription condition generally includes at least one of a threshold value and a threshold value, which reaches a preset value. The threshold value and the threshold value reach a preset numerical value, which are all different forms of expressions of numerical conditions, and when the numerical conditions are met, the first subscription conditions are met. For example, when the threshold is reached, or when the threshold is reached, it is determined that the first subscription condition is satisfied. In different scenarios, different expressions may be used.

In this embodiment of the present invention, the network slice information request or the network slice information subscription request (for example, the first subscription request) may include a geographic range corresponding to a network slice. The geographic scope is used to indicate the geographic scope of the requested network slice.

As described above, the first function obtains the first network slice related information through the second function and/or the network management system, and the first network slice related information may be obtained by the second function and/or the network management system from another function (referred to as a fourth function for convenience of description) and sent to the first function. The fourth function may be the third function described above, or may be a function other than the third function.

Specifically, the first network slice related information may be: the second function and/or the network management system is/are obtained by sending a network slice information request message to the fourth function; and/or the second function and/or the network management system are/is obtained by sending a second subscription request of the network slice information to the fourth function, wherein the second subscription request comprises a second subscription condition.

The second subscription condition may be obtained by the second function and/or the network management system after the geographic range to service range conversion or mapping is performed on the first subscription condition, and the first subscription condition is sent by the first function to the second function and/or the network management system. For example, the first subscription request sent by the first function includes a geographic range and a first subscription condition corresponding to a network slice, after receiving the first subscription request sent by the first function, the second function and/or the network management system performs conversion or mapping from the geographic range to the service range on the first subscription condition to obtain a second subscription condition, and then the second function and/or the network management system sends a second subscription request to the fourth function, where the second subscription request includes the second subscription condition. And subsequently, when a fourth function meets a second subscription condition, sending the relevant information of the first network slice to the second function and/or a network management system. Here, the above conversion or mapping from the geographic range to the service range may be performed according to the ratio of the service range of the fourth function in the geographic range in the first subscription condition.

In an embodiment of the present invention, the information related to the first network slice includes:

and/or the presence of a gas in the gas,

at least one second function aggregated network slice information.

That is, the network slice information corresponding to the same network slice may be obtained from a different second function or network management system. The network slice information may specifically include at least one of: the number of users accessed by the network slice and the number of sessions accessed by the network slice.

After the step 21, the first function obtains second network slice related information based on the first network slice related information. For example, the first function processes the information related to the first network slice according to the network slice identifier to obtain the information related to the second network slice. That is, the first function processes network slice information of the same network slice to generate second network slice related information.

Here, the processing of the first network slice related information includes at least one of the following processing modes: polymerization treatment, addition treatment and filtration treatment. Wherein:

the above polymerization treatment means: and summarizing the network slice information of the same network slice from each function and/or network management system to generate a set of the network slice information comprising the slice.

The addition processing means: the network slice information of the same network slice from each function and/or network management system is added, for example, the number of users accessed by the same network slice needs to be added, so as to obtain the total number of users accessed by the slice. Also for example, due to user mobility, the same network slice information needs to be added.

The filtration treatment is: and filtering the network slice information meeting the preset filtering condition.

Before the step 21, the first function may further receive a first request message for network slice lifecycle management of the first user, where the first request message includes network slice requirement information. Then, the first function triggers a second function and/or a network management system to execute network slice Life Cycle Management (LCM) operation according to the first request message. In addition, the first function may further receive an operation result sent by the second function and/or the network management system to the AF after executing the network slicing LCM operation, and send the operation result to the first user.

In addition, the first request message may further include at least one of the following:

indication information whether the first function is authorized to perform network slice lifecycle management operations;

indicators, events or data to be monitored;

a threshold corresponding to an index, event or data to be monitored.

In this way, after receiving the first request message, the first function may further determine whether the first user is trusted and whether the first function is authorized to perform a network slice lifecycle management operation. And then, under the condition that the user is credible and the first function is authorized to carry out network slice life cycle management operation, triggering a second function and/or a network management system to execute network slice LCM operation according to the first request message.

Here, the first function triggers the second function and/or the network management system executes a network slice LCM operation, which may specifically be: the first function determines a first operation of network slice lifecycle management according to the first request message and the collected network information related to the network slice; then, through an interface (such as an OAM interface) between the first function and the second function and/or the network management system, the second function and/or the network management system is triggered to execute the first operation of the network slice lifecycle management.

Further, in step 21, the first function may further determine whether to request or subscribe to an index, an event, or data related to the network slice according to the first request message; and under the condition that subscription is needed, requesting or subscribing the related indexes, events or data from the second function and/or the network management system, and receiving the first network slice information sent by the second function and/or the network management system.

In addition, it should be noted that various functions described herein, such as the first function, the second function, the third function, the fourth function, etc., may also be referred to as functional entities, functional modules or functional units (e.g., the first functional entity, the first functional module, the first functional unit, the second functional entity, the second functional module, the second functional unit, etc.). Here, the functions may be implemented by a separate hardware device, or may be a function of a certain hardware device/software system.

Referring to fig. 3, a flowchart of a method for acquiring network slice information when applied to a second function or a network management system according to an embodiment of the present invention is provided. As shown in fig. 3, the method includes:

step 31, the network management system or the second function sends the first network slice related information to the first function.

Here, the first function is a network slice capability management function and/or an application function, and the second function is at least one of a network openness function, a network slice admission control function, and a network data analysis function. The information related to the first network slice, which is sent by the second function to the first function, specifically includes: first network slice related information provided by the second function; or the third function provides the first network slice related information. The third function may be at least one of NSACF and NWDAF.

Through the steps, the network management system or the second function can provide the first function with the relevant information of the first network slice, so that support is provided for realizing the life cycle management of the network slice.

Here, in step 31, the network management system or the second function may provide the first network slice information to the first function according to a request or subscription of the first function. For example:

and/or the presence of a gas in the gas,

Here, the first subscription condition is set based on analysis of the first network slice related information by the third function. The first subscription condition comprises at least one of a threshold value and a threshold value, and the threshold value reaches a preset value.

As described above, the first network slice related information sent by the second function and/or the network management system to the first function may be obtained by sending a network slice information request message to the fourth function; and/or the second subscription request is obtained by sending the network slice information to the fourth function, and the second subscription request comprises a second subscription condition.

In addition, the network slice information request or the network slice information subscription request (e.g., the first subscription request) includes a geographic range corresponding to the network slice. The second subscription condition is obtained by the second function and/or the network management system after the geographic range to service range conversion or mapping is performed on the first subscription condition, and the first subscription condition is sent to the second function and/or the network management system by the first function.

The first network slice related information may specifically include:

and/or the presence of a gas in the gas,

at least one second function aggregated network slice information.

The network slice information includes at least one of: the number of users accessed by the network slice and the number of sessions accessed by the network slice.

Before the step 31, the network management system or the second function may further execute a network slice lifecycle management (LCM) operation according to the trigger of the first function. In addition, the network management system or the second function can also execute network slice LCM operation and send the operation result of the LCM operation to the first function. The triggering may specifically be that a request for triggering the execution of the LCM operation sent by the first function is received through a network management system or an interface (such as an OAM interface) between the second function and the first function.

Referring to fig. 4, an embodiment of the present invention further provides a slice management method, applied to a first function, including:

and 41, triggering the network management system to perform network slice management by the first function.

Here, the first function may specifically be a network slice capability management function and/or an application function (e.g., NSCM). The first function can send a request message for triggering execution of network slice management to the network management system through an interface between the first function and the network management system, and trigger the network management system to execute the network slice management.

The network slice management comprises at least one of: creating a network slice, deleting the network slice, modifying the network slice, adjusting a threshold of the maximum user access number of the network slice, and adjusting a threshold of the maximum session number of the network slice. In addition, after the step 41, the first function may further receive a result of network slice management sent by the network management system, and send the result to a corresponding user.

Through the steps, the first function can trigger the network management system to execute the network slice management, so that the slice life cycle management function is realized.

Here, before step 41, the first function may further obtain first network slice related information through a second function and/or a network management system, and obtain second network slice related information based on the first network slice related information. For obtaining the first and second network slice related information, reference may be made to the above description, which is not repeated herein.

As an optional implementation manner, the first function determines whether the network slice requirement of the industry platform is met according to at least one of the first network slice related information, the second network slice related information, and the network state information, and if not, the above step 41 is performed to trigger the network management system to perform network slice management.

Here, the network status information may include, but is not limited to, the following information: the network service quality information detected from the application layer and the monitored network status data may specifically include network delay of idle network resources, network throughput, and the like (which may be used to determine whether a user requirement may be met through slice management).

As another optional implementation manner, after the second network slice related information is obtained, the first function may determine whether the network slice requirement of the industry platform is met according to at least one of the first network slice related information, the second network slice related information, and the network state information, send an inquiry message inquiring whether optimization operation needs to be performed to the industry platform if the industry platform is not met, and enter step 41 when the industry platform selects to perform optimization operation, so as to trigger the network management system to perform network slice management.

Referring to fig. 5, a method for adjusting network slice resources according to an embodiment of the present invention, when applied to a network management system, includes:

and step 51, performing network slice management according to the triggering of the first function.

Here, the network management system may receive, through an interface between the first function and the network management system, a request message that triggers execution of network slice resource adjustment sent by the first function, then execute network slice management according to the request message, and send a slice management result to the first function.

Specifically, the network slice management includes at least one of: creating a network slice, deleting the network slice, modifying the network slice, adjusting a threshold value of the maximum user access number of the network slice, and adjusting a threshold value of the maximum session number of the network slice.

Through the steps, the embodiment of the invention realizes the operation of triggering the slice life cycle management by the first function.

In the embodiment of the present invention, before step 51, the network management system may further provide the first function with information related to the first network slice. The first function can obtain the related information of the second network slice according to the related information of the first network slice, judge whether the network slice requirement of the user is met according to the related information of the second network slice and the collected network state information, and further determine whether the network management system needs to be triggered to carry out network slice management.

The above describes a method for acquiring network slice information and a method for adjusting slice resources according to an embodiment of the present invention. The above methods of embodiments of the present invention are described in detail below by way of more specific examples.

As shown in fig. 6, in the following example, the first function may be specifically an NSCM server (NSCM server), the second function may be specifically a control plane of a core network, and the network management system may be specifically a management plane of the core network.

In the NSCM architecture in this example, the interface between the NSCM server and the control plane of the 3GPP is N33, and an interface NSCE-OAM between the NSCM server and the management plane is added to interact with the network management system. The specific scheme flow is shown in fig. 7:

precondition S0: it is assumed that the NSCM has performed relevant authentication in the 5G core network and the network management system and is authorized to perform application layer network slice lifecycle management capability open relevant services.

And S1, the NSCM server receives a network slice life cycle management response request sent by a user. The request may be sent by the user by calling an interface to send the template. The template includes information such as the type of network slice requested by the user (whether it is dedicated), the desired quality of service, whether a subscription is required for monitoring the network status, etc.

The slice lifecycle management response request may specifically be sent from a VAL server to an NSCM server, that is, the NSCM server receives a first request message of the network slice lifecycle management of the first user, which is forwarded by the VAL server, where the first request message is sent to the VAL server by a VAL client on a user side.

The slice lifecycle management response request may also be sent by the VAL client to the NSCM server via the NSCM client. That is, the NSCM receives a first request message of the network slice lifecycle management of the first user, which is forwarded by an NSCM client on the user side, where the first request message is sent to the NSCM client by a VAL client on the user side.

And S2, the NSCM server confirms whether the first user is credible and authorized to perform corresponding LCM (slice lifecycle) operation according to the slice lifecycle management response request, and performs corresponding processing according to the received request and the existing network state information if the first user is credible and authorized.

For example, NSCM server determines that an LCM operation should be triggered, and triggers the core network management plane to execute the LCM operation by triggering through interface NSCE-OAM. Specifically, when the received network slice lifecycle management response request is a slice new creation request, it may be determined whether to trigger/invoke a slice creation request or a slice allocation request according to whether a slice resource exists.

And S3, the core network management surface executes corresponding LCM operation according to the triggering of the NSCM server, returns LCM operation response (LCM operation result) to the NSCM server according to the LCM operation, and the NSCM server sends the LCM operation response to the corresponding user. This step may also be performed after the event subscription of S4 is completed.

And S4, the NSCM server judges whether corresponding events and data subscription are needed or not, and performs corresponding operation.

For example, when the user subscribes to a service for the automated application layer slice lifecycle management, it is determined in step S4 that data related to network slice performance, such as performance measurement, needs to be subscribed to the management plane and the control plane. At this time, as shown in fig. 7, the automated application layer slice lifecycle management further comprises:

the preconditions are as follows: the user subscribes to the service.

S71, the NSCM subscribes/requests the related event (such as monitering) to the 5GC or the network management system according to the requirement of the user.

The subscription needs to indicate an index that needs to be monitored, and optionally, may also need to indicate a corresponding threshold.

S72.5GC returns a notification to the NSCM whether the subscription/request was successful.

S73, after the relevant event occurs or the request is received, the 5GC sends an event notice to the NSCM; alternatively, the 5GC periodically sends event notifications to the NSCM.

S74.NSCM (can be regarded as AF) optionally integrates data according to received event/notice to form data with slice granularity, judges whether the requirement of the user is met or not by combining network state information, if the requirement is not met, triggers corresponding subsequent optimization flow, and then can enter step S75 or step S77;

s75, optionally, if the user requires the semi-intelligent application-enabled layer to slice LCM, the NSCM notifies the user of the change of network status information, queries whether to up/down the user SLA, or triggers a corresponding optimization operation, and then proceeds to step S76.

And S76, optionally, returning semi-intelligent LCM response information by the user. If the selection does not involve subsequent adjustment operations, such as adjusting the SLA to accommodate the current network state, the process ends; if the selection involves a subsequent operation, such as a slice needs to be scaled to meet the existing SLA requirements, S77 is entered.

And S77, NSCM carries out corresponding requirement examination and judgment, and triggers related management plane LCM operation through NSCE-OAM.

And S78, the management surface returns the LCM operation result through the NSCE-OAM interface.

And S79, returning the operation result of the management plane LCM to the user by the NSCM.

In the following, with reference to fig. 8, another example to which the above method of the present invention is applied is provided, in which intelligent Slice management based on NSACF (Network Slice access Control Function) is implemented.

This example initiates a request for intelligent slice management by a vertical server.

The precondition is as follows:

NSCM server is a trusted third party that can subscribe to 5GS services; configured with the appropriate NEF, and having a corresponding subscribe ID to subscribe to analysis information, enforce inbound restrictions (i.e., parameters and/or parameter values), etc.

This example includes the steps of:

and S81, the vertical server initiates a request for intelligent slice management, wherein the request comprises contents such as slice requirements (delay, throughput, load, supported maximum user quantity, supported maximum PDU session quantity and the like), and the request indicates whether the NSCM server is authorized to carry out intelligent slice management or not, and indicates indexes needing to be monitored and corresponding thresholds (optional). (the index that can be monitored can be given by means of a slice template).

S82, after receiving the request, the NSCM server confirms that the user is credible and authorized to perform corresponding LCM operation, if the user is credible and authorized, a service profile (service profile) is filled, and the Allocationsi request can be triggered by using an NSCE-OAM interface.

And S83. The response (response) of the LCM operation is returned after the NSCM server completes the corresponding slicing operation, and the step can also be carried out after the step S84 is completed.

S84, according to the slice requirements of the user and the indexes needing to be monitored, NSCM server/AF subscribes (can carry threshold values)/requests corresponding events. If the number of sessions/the number of UE accessed to the PDU need to be monitored, the network slice data or NDWAF of the NSACF is obtained through the NEF/network management system to monitor the slice access number or the slice load (load); if performance (performance) data is monitored, the relevant data can be obtained through the NWDAF/network management system.

S85. When the threshold is triggered, the NSACF may Notify the NEF through NSACF _ SliceEventExposure _ Notification (Event ID, event Filter, event Reporting Information, notification correction Information), and the NEF informs the NSCM server of the slice state change.

And S86, judging whether the user requirements are met or not by the NSCM server according to the network slice state, if the user requirements cannot be met, judging whether a new slice is needed or not, if the user requirements cannot be met, performing corresponding LCM operation through an NSCE-OAM interface, and if the slice is needed to be modified, sending a ModifyNsi request.

And S87. The NSCM server optionally informs the VAL server according to the corresponding LCM operation result.

The present invention can also be applied to the following examples, which are not described again for saving space:

carrying out intelligent slice management based on OAM performance measurement NotifyThreshold cross;

and performing intelligent configuration management based on early notification.

It can be seen from the above that, the method of the embodiment of the invention can help the vertical industry to shield the complex network operation details, and realize the intelligent network slice life cycle management. In addition, the embodiment of the invention can more safely open the network management capability.
