Detailed Description
The present application will be described with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
The 3rd Generation Partnership Project (3 GPP) standard defines that a Core Network slice subnet is composed of a plurality of fifth Generation Core Network elements (5 GC NF), such as: access and Mobility Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), Unified Data Management (UDM), Unified Data storage (UDR), Network Slice Selection Function (NSSF), and the like. In the NF example, that is, the core network element in the embodiment of the present application, the network slice capacity control is also the control of the sub-slice capacity of the core network element, and for the capacity control of other sub-slices, reference may be made to the network slice capacity control method described in each embodiment.
Fig. 1 is a flowchart of a network slice capacity setting method according to an embodiment. The method of the embodiment can be applied to a network slice management network element. As shown in fig. 1, the method provided in this embodiment includes steps 110 and 130.
In step 110, slice capacity parameters are obtained, including capacity requirements or service level agreement parameters for the network slices.
In step 120, a network slice capacity threshold corresponding to a slice instance serving the network slice is determined according to the slice capacity parameter.
In step 130, a setting instruction of network slice capacity is sent to each slice instance, where the setting instruction includes a corresponding network slice capacity threshold.
In this embodiment, the Network Slice Management Network element refers to a Network Slice Management System (NSMS), and includes a Communication Service Management Function (CSMF), a Network Slice Management Function (NSMF), and a Network Slice Subnet Management Function (NSSMF) defined by 3 GPP. By adding a logic module or component for decomposing or mapping the capacity requirement or SLA parameter of a network slice in NSMS, the logic module or component is used for decomposing or mapping the slice capacity parameter to each slice instance for providing service for the network slice, thereby converting the network slice capacity requirement from a client into the capacity requirement of an NF instance in the network slice; by sending a setting instruction to each slice instance to inform each slice instance to set a corresponding network slice capacity threshold, each slice instance can efficiently manage online users and sessions according to the network slice capacity threshold, and a perfect network slice capacity setting mechanism is established, so that the controllability and the service stability of the network slice capacity are improved.
In an embodiment, the network slice capacity threshold comprises: the maximum number of static users, the maximum number of online dynamic users, and the maximum number of online dynamic sessions.
When the operator provides the network slice, the capacity of the network slice is defined in the SLA parameter, for example, the maximum static user number, the maximum online dynamic user number or the session number supported by the network slice instance is defined. In this embodiment, according to the capacity requirement of a network slice or preset SLA parameters, the network slice is decomposed into slice instances, and a network slice capacity threshold value of each slice instance is determined, where the network slice capacity threshold value includes three items: the method comprises the steps of obtaining a maximum static user number, a maximum online dynamic user number and a maximum online dynamic session number, wherein the maximum static user number can be managed and maintained through NF instances such as UDM or UDR, and the maximum online dynamic user number or session number can be maintained through NF instances such as AMF, SMF or UPF.
In this embodiment, a Network Slice uses Single Network Slice selection auxiliary Information (S-NSSAI) as an indication, and the control of the Network Slice capacity is control of the maximum static user number and the maximum online dynamic user number or session number based on S-NSSAI.
For example, a slice volume parameter is acquired in step 110. For a network slice (e.g., S-NSSAI ═ 011A0B01), the NSMS receives the capacity requirement of the user or obtains the SLA parameter indicating that the slice capacity parameter for the network slice is:
NSSAI＝011A0B01
{
the maximum static user number is 100 ten thousand;
the maximum online dynamic user number is 10 ten thousand;
the maximum online dynamic session number is 30 ten thousand;
}
in step 120, a network slice capacity threshold corresponding to a slice instance serving the network slice is determined, where at least one slice instance is provided. In this process, the NSMS decomposes or maps the slice capacity parameter of the slice instance to each slice instance corresponding to the S-NSSAI, and may specifically decompose to each NF instance within the slice instance. For example, S-NSSAI 011A0B01 corresponds to slice instance 1 and slice instance 2, and for the maximum number of static users, it can be decomposed into:
slice example 1, in the case of S-NSSAI 011A0B01, the maximum number of static users is, for example, 30 ten thousand, managed by UDM or UDR;
slice example 2, in the case of S-NSSAI 011A0B01, the maximum number of static users is, for example, 70 ten thousand, managed by UDM or UDR;
on the basis, the slice example 1 can control the number of the static users in the slice example to be not more than 30 thousands, and the slice example 2 can control the number of the static users in the slice example to be not more than 70 thousands, so that the stability of the service is ensured.
In some embodiments, the slice instance 1 and the slice instance 2 may share the UDM or the UDR, and for the maximum static user number, the maximum static user number directly mapped as the shared UDM or the UDR in the case of S-NSSAI 011A0B01 is 100 ten thousand.
For the maximum online dynamic user number, the method can be decomposed into:
example 1 of slicing, in the case of S-NSSAI 011A0B01, the maximum number of online dynamic users is, for example, 3 ten thousand, and is managed by AMF, SMF, or UPF;
example 2 of slicing, in the case of S-NSSAI 011A0B01, the maximum number of online dynamic users is, for example, 7 ten thousand, and is managed by AMF, SMF, or UPF;
on the basis, the slicing example 1 can control the number of online dynamic users in the slicing example to be not more than 3 thousands, and the slicing example 2 can control the number of online dynamic users in the slicing example to be not more than 7 thousands, so that the stability of the service is ensured.
For the maximum number of online dynamic sessions, it can be decomposed as:
example 1, slicing, with S-NSSAI 011A0B01, the maximum number of online dynamic sessions (e.g., 9 ten thousand), managed by AMF, SMF, or UPF;
slice example 2, with S-NSSAI 011A0B01, the maximum number of online dynamic sessions (e.g., 21 ten thousand) is managed by AMF, SMF, or UPF;
on this basis, slice example 1 can control the number of online dynamic sessions in it to be not more than 9 ten thousand, and slice example 2 can control the number of online dynamic sessions in it to be not more than 21 ten thousand, thereby ensuring the stability of the service.
In step 130, the NSMS may determine a network slice capacity threshold corresponding to each slice instance or NF instance according to the above decomposition condition, and issue a setting instruction to a specific NF instance in each slice instance through an Element Management System (EMS), so as to implement setting of a network slice capacity threshold based on S-NSSAI for each slice instance. For example:
the maximum number of static users of the UDM or UDR shared by the slice example 1 and the slice example 2 is set to 100 ten thousand at S-NSSAI 011A0B 01;
example 1 of slicing, the maximum number of online users of AMF, SMF, or UPF in the case of S-NSSAI ═ 011A0B01 is set to 3 ten thousand;
example 2 of slicing, the maximum number of online users of AMF, SMF, or UPF in the case of S-NSSAI ═ 011A0B01 is set to 7 ten thousand;
example 1.AMF/SMF/UPF maximum number of online dynamic sessions for S-NSSAI 011A0B01 is set to 9 ten thousand;
example 2.AMF/SMF/UPF maximum number of online dynamic sessions for S-NSSAI 011A0B01 is set to 21 ten thousand;
it should be noted that the setting instruction sent to the slice example 1 only needs to carry the network slice capacity threshold corresponding to the slice example 1; the setting instruction sent to the slice instance 2 only needs to carry the network slice capacity threshold corresponding to the slice instance 2, and the two are independent, and are respectively set and controlled.
In one embodiment, the method further comprises: receiving failure setting information returned by a target slice example, wherein the target slice example is a slice example of which the corresponding network slice capacity threshold value exceeds the residual capacity supported by the current slice example; and adjusting the network slice capacity threshold corresponding to the target slice example according to the setting failure information.
In this embodiment, the NSMS further receives the setting failure information returned by the target slice instance, and may obtain the slice capacity parameter again or obtain a processing instruction (for example, a capacity expansion instruction) of a user or an Operation Support System (OSS) according to the setting failure information, so as to adjust a network slice capacity threshold corresponding to the target slice instance and resend the setting instruction. The remaining capacity refers to the network slice capacity that can be supported for the current slice instance, excluding the network slice capacity allocated to other S-NSSAIs. For the target slice instance, the maximum supported capacity is given in its License, e.g. for the AMF in the target slice instance, the maximum number of online dynamic sessions is given for 20 ten thousand for one of the maximum supported capacities for all S-NSSAIs. Under the condition that the maximum online dynamic session number of the residual capacity is 20 ten thousand under the condition that the maximum online dynamic session number of other S-NSSAIs is not allocated, under the condition, for the current S-NSSAI, if the maximum online dynamic session number decomposed into the network slice capacity threshold value of the target slice example is 21 ten thousand and exceeds the residual capacity supported by the slice example, the target slice example feeds back a setting failure instruction to the NSMS; for another example, for the AMF in the target slice instance, a certain maximum online dynamic session number is already allocated for other S-NSSAIs, assuming that the maximum online dynamic session number of the remaining capacity is 10 ten thousand, and the maximum online dynamic session number allocated for the current S-NSSAI is 12 ten thousand, which exceeds the maximum online dynamic session number of the remaining capacity (it may also be understood that after the maximum online dynamic session number set for the current S-NSSAI is added, the maximum online dynamic session number set for all S-NSSAIs exceeds the maximum online dynamic session number of the maximum capacity given in License), the network slice capacity threshold setting for the current NF instance is rejected, and a setting failure instruction is fed back to the NSMS. The NSMS may reacquire the slice capacity parameter according to the setting failure information, or adjust the network slice capacity threshold corresponding to the target slice instance and resend the setting instruction.
Fig. 2 is a flowchart of a network slice capacity control method according to an embodiment. The method of the present embodiment may be applied to a core network element, such as AMF, UDF, etc. As shown in fig. 2, the method provided in the present embodiment includes steps 210 and 230.
In step 210, a setting instruction of a network slice capacity is received, the setting instruction including a network slice capacity threshold of a current slice instance.
In step 220, a network slice capacity threshold is set according to the setting instruction.
In step 230, the network slice capacity provided to the user is controlled according to the network slice capacity threshold.
In this embodiment, an S-NSSAI-based capacity control logic module or component is added to the slice instance to implement S-NSSAI-based capacity control for the slice instance and capacity conflict management in License. After receiving a setting instruction sent by the NSMS through the EMS, the slice example sets a network slice capacity threshold according to the setting instruction, thereby controlling the network slice capacity provided for the user, carrying out efficient management on the online user and the session, and establishing a perfect network slice capacity control mechanism, thereby improving the controllability and the service stability of the network slice capacity. The slice instance may be specifically a 5GC NF instance, for example, the maximum static user number may be controlled by an NF instance such as UDM or UDR, and the maximum online dynamic user number or session number may be controlled by an NF instance such as AMF, SMF, or UPF.
In an embodiment, the network slice capacity threshold comprises: the maximum number of static users, the maximum number of online dynamic users, and the maximum number of online dynamic sessions.
In an embodiment, the setting instruction received by one slice instance may only include the corresponding network slice capacity threshold, and does not need to include the network slice capacity threshold under other slice instances (or under other S-NSSAIs), and each slice instance independently sets the respective network slice capacity threshold and independently controls the respective network slice capacity
In one embodiment, the controlling the network slice capacity provided to the user according to the network slice capacity threshold comprises: denying subscription with, or generating a session with, the user requesting access after the network slice capacity provided to the user exceeds the network slice capacity threshold.
In this embodiment, when the network slice capacity provided to the user exceeds the set network slice capacity threshold, the user requesting access is denied a subscription, or a session is denied to the user requesting access, so that the network slice is not overloaded, and the service stability is ensured.
Fig. 3 is a flowchart of an S-NSSAI-based network slice capacity control process according to an embodiment.
As shown in fig. 3:
in step 201, a setting instruction of a network slice capacity is received, wherein the setting instruction comprises a network slice capacity threshold of a current slice instance.
In this step, the slice instance receives a capacity threshold setting instruction based on S-NSSAI from the EMS, and the slice instance may be specifically a 5GC NF instance (e.g., AMF, SMF, or UPF).
In step 202, a network slice capacity threshold is set according to the setting instruction.
In this step, the 5GC NF instance sets the network slice capacity threshold supported by the S-NSSAI, for example, if AMF, SMF or UPF is 011A0B01, the maximum number of online dynamic sessions is 9 ten thousand; when the UDM or UDR is set to S-NSSAI 011A0B01, the maximum number of static users is 30 ten thousand, for example.
In step 203, it is calculated in real time whether the network slice capacity provided to the user exceeds a network slice capacity threshold or a given value of License? If yes, go to step S204, otherwise, go to step S203.
In step 204, slice volume alarm information is generated and the NSMS is notified via the EMS.
In step 205, the slice is denied access to add new subscribers or new users.
In an embodiment, before setting the network slice capacity threshold according to the setting instruction, the method further includes: and if the network slice capacity threshold exceeds the residual capacity supported by the current slice example, generating setting failure information and sending the setting failure information to a network slice management network element.
In this embodiment, in the process of setting the network slice capacity threshold, it is also necessary to consider whether the maximum capacity corresponding to the item given by the License of the NF instance itself will be exceeded after adding one threshold of the current S-NSSAI, and if not, the step 202 is continuously executed; if the setting is exceeded, the setting is refused, setting failure information is fed back to the NSMS through the EMS, and the processing instruction of the next step is waited.
Fig. 4 is a schematic diagram of a network slice capacity threshold setting end process according to an embodiment. As shown in fig. 4, for NSMS, the process of determining the network slice capacity threshold is as follows:
1) license management. The License management system of the EMS sets the maximum capacity supported by each slice instance (specifically 5GC NF instance), which is the upper limit of the sum of network slice capacity thresholds supported by each NF instance for a plurality of S-NSSAIs, for example, the sum of the maximum static user numbers allocated by all S-NSSAIs given the UDM for the slice instance 1 in the License must not exceed 200 ten thousand.
2) And acquiring a slice volume parameter. The capacity requirements for network slicing may be obtained or SLA parameters may be obtained.
3) And determining NF instances for providing services for the network slice, and decomposing the slice capacity parameters to the NF instances to obtain network slice capacity thresholds corresponding to the NF instances.
4) The NF slice level capacity counter sets the request. The NSMS sends a set instruction to the EMS including the network slice capacity threshold for each NF instance based on the S-NSSAI.
5) The NF slice level capacity counter sets the request. The EMS sends a setting instruction to specific NF instances in the slice, and the setting instruction sent to each NF instance comprises a network slice capacity threshold value of the NF instance based on S-NSSAI.
6) And controlling the capacity of the slicing level. And the NF instance in the slice receives the capacity setting instruction, sets a network slice capacity threshold based on the S-NSSAI, and starts network slice capacity threshold control.
It should be noted that, in the setting process, if the NF instance determines that (any one of) the network slice capacity threshold exceeds (a corresponding one of) the remaining capacity supported by the NF instance, or determines that (any one of) the network slice capacity threshold is added and then exceeds (a corresponding one of) the maximum capacity supported by the NF instance, the setting is rejected.
7) The NF chip level capacity counter sets the response. The NF instance returns a response message set by the network slice capacity threshold.
8) The NF chip level capacity counter sets the response. The response message for the network slice capacity threshold setting reaches the NSMS via the EMS.
Fig. 5 is a schematic diagram of a network slice capacity control end flow according to an embodiment. As shown in fig. 5, for NF, the process of network slice capacity threshold control is as follows:
a) the equipment normally operates, and the slicing user signs a contract and uses the service provided by the slicing.
b) And controlling the capacity of the slicing level. Calculating the actual network slice capacity based on the S-NSSAI in real time, comparing the actual network slice capacity with the set network slice capacity threshold and the License set value, and executing step c) if the actual network slice capacity exceeds the set network slice capacity threshold and the License set value; otherwise, b) is executed circularly, and the network slice capacity is continuously monitored.
c) And (4) the NF slice level capacity exceeds the limit, and warning and informing. The 5GC NF instance generates a capacity warning message based on the S-NSSAI.
d) And (4) the NF slice level capacity exceeds the limit, and warning and informing. The capacity warning message is sent to the NSMS via the EMS.
e) The OSS or customer is notified of the process. The NSMS sends the capacity warning message to the OSS or the client, which decides the processing action.
f) And (3) slicing level capacity overrun treatment: denying the newly signed user or denying the user access to the new session. For NF instances, if it is UDM or UDR, rejecting the newly signed user; if it is AMF, SMF or UPF, etc., then the user is denied access to generate a new session.
g) And (5) carrying out slicing level capacity overrun treatment. NSMS performs processing according to the OSS or customer processing actions, for example: the slice level slice capacity alarm information is processed by expanding or adjusting the network slice capacity threshold, and the processing may trigger the setting process of the network slice capacity threshold or the License expanding process of the NF again.
The network slice capacity threshold setting and control procedure of the above embodiment is explained below by specific examples.
For example, a user purchases and uses a slicing service denoted by S-NSSAI ═ 011A0B01, and selects SLA parameters and capacity requirements, the slicing capacity parameters being:
S-NSSAI＝011A0B01
{
the maximum static user number is 100 ten thousand;
the maximum online dynamic user number is 10 ten thousand;
the maximum online dynamic session number is 30 ten thousand;
}
an operator provides service for the user by adopting an independent slice example, 5GC NF is deployed in the slice example, when the actual network slice capacity exceeds the value of the slice capacity parameter, the UDM or the UDR rejects a new user belonging to the slice service to open an account, the AMF, the SMF or the UPF rejects a new access request initiated by the user and belonging to the slice service, and informs the user that the slice capacity reaches a threshold value through slice capacity alarm information to remind the user of expanding or performing other processing. The end-to-end process is specifically as follows:
step 1: the maximum capacity supported by each 5GC NF instance in each slice instance is given by the License management system of the EMS. For example: the maximum static user number of a given UDM or UDR is 1200 ten thousand; the maximum online dynamic user number of the AMF, the SMF or the UPF is 200 ten thousand, and the maximum online dynamic session number is 600 ten thousand;
step 2: acquiring the capacity requirement of the network slice service to be purchased provided by the user or acquiring SLA parameters:
S-NSSAI＝011A0B01
{
the maximum static user number is 100 ten thousand;
the maximum online dynamic user number is 10 ten thousand;
the maximum online dynamic session number is 30 ten thousand;
}
and step 3: determining an NF instance providing service for the network slice, and decomposing the slice capacity parameter to each NF instance in each slice instance by the NSMS to obtain a network slice capacity threshold corresponding to each NF instance, taking slice instance 1 and slice instance 2 as examples:
for example 1 slice:
the maximum number of static users of the UDM or UDR is 100 ten thousand in the case of S-NSSAI 011A0B 01;
the maximum online dynamic user number of AMF, SMF or UPF is 10 ten thousand under the condition that S-NSSAI is 011A0B 01;
the maximum number of online dynamic sessions of the AMF, SMF or UPF is 30 ten thousand in the case of S-NSSAI of 011A0B 01;
and 4, step 4: the NSMS sends a setting instruction to the EMS, wherein the setting instruction is used for indicating each NF instance to set a network slice capacity threshold value based on the S-NSSAI according to the setting instruction;
and 5: the EMS sends a setting command based on S-NSSAI to a specific NF instance;
step 6: the NF instance receives the setting instruction, sets a network slice capacity threshold based on the S-NSSAI according to the setting instruction, and starts a network slice capacity threshold control process, for example, for the AMF, SMF, or UPF of the slice instance 1, sets a maximum online dynamic user number of 10 ten thousand and a maximum online dynamic session number of 30 ten thousand when the S-NSSAI is 011A0B 01;
and 7: the business is normally carried out, and a slicing user signs a contract and uses the service provided by the slicing;
and 8: the NF example carries out real-time statistics on the network slice capacity based on the S-NSSAI, judges whether the network slice capacity is larger than a set network slice capacity threshold value or a given value in License, and if the network slice capacity is larger than the set network slice capacity threshold value or the given value in License, the NF example goes to the step 9; otherwise, circularly executing the step 8, and checking the corresponding relation between the actual network slice capacity based on the S-NSSAI and the set network slice capacity threshold value or the given value in the License;
and step 9: generating slice capacity alarm information based on the S-NSSAI, sending the slice capacity alarm information to the NSMS through the EMS, and determining the processing action of capacity overrun alarm by the OSS or a client;
step 10: rejecting the newly signed user if the current NF instance is UDM or UDR; if the current NF instance is AMF, SMF or UPF, the user is denied access to generate a new session.
Step 11: the NSMS processes the slice capacity alarm message according to the OSS or the processing action (e.g. capacity expansion) of the client, and the processing may trigger the setting process of the network slice capacity threshold or the License capacity expansion process again.
The embodiment of the application also provides a network slice capacity setting device. Fig. 6 is a schematic structural diagram of a network slice capacity setting apparatus according to an embodiment. As shown in fig. 6, the network slice capacity setting apparatus includes: an acquisition module 310, a threshold determination module 320, and an instruction transmission module 330.
