Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention discloses a method for sharing NF user permission among network slices, which is shown in figure 1 and comprises the following steps:
step S11: and monitoring the user permission number of the target type NF in each network slice and the running state of each network slice to obtain a corresponding monitoring result.
It should be noted that, in the embodiment of the present application, the network slice may be a network slice that is created in advance and has a corresponding user license assigned to each type of NF thereof, or may be a network slice that is created by the slice manager when the network slice needs to be used and has a corresponding user license assigned to each type of NF in the network slice.
It is understood that the monitoring process may specifically include recording the user license type and amount information of each type NF in each network slice.
For example, when the slice a rarely or even hardly adjusts the user permission during the operation, and the number of times or frequency of the user permission of the slices B and C needs to be adjusted during the operation is high, in order to reduce the working pressure of the slice manager, the number of the user permissions of the target type NF in each network slice of the slices B and C and the operation state of each network slice may be monitored in a focused manner or only need to be monitored. Similarly, the target type NF may be a class of NFs in each network slice, or may be multiple classes of NFs in each network slice.
Step S12: judging whether a network slice which needs to perform user permission adjustment operation corresponding to the target type NF exists or not according to the monitoring result; if yes, corresponding user permission adjustment operation is carried out on the target type NF in the network slice through an NF user permission storage library.
The NF user permission storage library is a database used for storing user permissions to be distributed corresponding to the target type NF.
It can be understood that, as can be known from step S11, the monitoring result in the embodiment of the present application includes the operation condition of each network slice and the number of user permissions of the target type NF in each network slice, so that it can be determined whether there is a network slice that needs to perform the user permission adjustment operation corresponding to the target type NF according to the monitoring result; if yes, the target type NF in the network slice may be adjusted by increasing or decreasing the user permission through the NF user permission repository.
The method for sharing NF user permission among network slices can monitor the user permission using condition of the target type NF in each network slice and the actual operation condition of each network slice in real time, and further can judge whether the user permission of the target type NF in the network slice needs to be adjusted according to the corresponding monitoring result, thereby avoiding that whether the user permission of the target type NF in the corresponding network slice needs to be adjusted is artificially judged in the operation process of the network slice, even the corresponding adjustment operation is manually completed, effectively realizing the purpose of sharing the same NF user permission among the network slices, and improving the using efficiency of the user permission.
The embodiment of the invention discloses a specific method for sharing NF user permission among network slices, and compared with the previous embodiment, the embodiment further explains and optimizes the technical scheme. Referring to fig. 2, the method specifically includes the following steps:
step S21: and monitoring the user permission number of the target type NF in each network slice and the running state of each network slice to obtain a corresponding monitoring result.
It should be noted that, in this embodiment, the load condition of the target type NF in the corresponding network slice may be determined according to the operating condition and the user permission number of the target type NF in each network slice, in other words, the monitoring result includes the load condition of the target type NF in each network slice. For other related descriptions, reference may be made to the above embodiments, which are not described herein again.
Step S22: judging whether a network slice which needs to perform user permission recovery operation corresponding to the target type NF exists or not according to the monitoring result; if so, the flow proceeds to step S23.
Step S23: judging whether the load condition of the target type NF in any network slice is in an idle state, if so, sending a user permission recovery request to the target type NF in the network slice, and after receiving a recovery response of the NF, recovering the corresponding user permission in the target type NF in the network slice according to a preset rule through the NF user permission storage library to obtain the user permission to be distributed.
In this embodiment of the present application, the idle state may be a state in which the number of user permissions of any category NF in the network slice exceeds a first preset threshold for normal operation of the category NF. The first preset threshold may be a default value or a value set in actual operation.
Referring to fig. 3, step S22 and step S23 in this embodiment may be replaced by the following specific steps:
step S32: judging whether a network slice which needs to perform user permission allocation operation corresponding to the target type NF exists or not according to the monitoring result; if so, the flow proceeds to step S33.
Step S33: and judging whether the load condition of the target type NF in any network slice is in a busy state, if so, sending a user permission allocation request to the target type NF in the network slice, and after receiving an allocation response returned by the NF, allocating corresponding user permission to be allocated to the target type NF in the network slice through the NF user permission storage library.
Considering that when there is a network slice that needs to perform the user license allocation operation corresponding to the target type NF, and there is not enough corresponding user licenses to be allocated in the NF user license repository, and the target type NF in other slices is in a normal operating condition, before allocating corresponding user licenses to be allocated to the target type NF in the network slice through the NF user license repository in step S33, the method may further include:
and judging whether the number of the user licenses to be distributed, corresponding to the target type NF, in the NF user license repository currently meets the current distribution condition, if not, correspondingly recovering the user licenses corresponding to the target type NF in other network slices through the NF user license repository to obtain the user licenses to be distributed.
It should be noted that, according to the second preset threshold, the NF user permission repository may perform corresponding recovery on the user permissions corresponding to the target type NF in the other network slices, so as to obtain the user permissions to be allocated, for example, 5000 user permissions are theoretically required for normal operation of the target type NF in the network slice, and in practice, the normal operation of the target type NF is still not affected when the number of the user permissions in the target type NF is 4500, that is, the second preset threshold is 4500, and at this time, part of the user permissions exceeding 4500 in the other network slices may be recovered until the current allocation condition is satisfied.
It should be noted that steps S22, S23, S32, and S33 may also be executed separately, or may also be executed simultaneously after corresponding combination, as long as corresponding conditions are satisfied, as shown in fig. 4, where fig. 4 is a schematic diagram of a flow of adjusting user permissions of a target type NF in any network slice in this embodiment.
Step S41: the slice manager creates two network slices and assigns initial user permissions to each NF in the two slices, respectively.
Step S42: the slice manager monitors the user permission use condition of NF in each network slice;
step S43: the slice manager finds that the user-granted resources of NF _ a-1 in network slice 1 are strained.
Step S44: the slice manager finds that there is currently no free user permission.
Step S45: the slice manager detects that there is a surplus of user permissions found for NF _ a-2 in network slice 2.
Step S46: the slice manager sends an NF user license reclaim request to NF _ a-2 in network slice 2 requesting 5 universal user licenses to be reclaimed.
Step S47: the NF _ a-2 in network slice 2 returns an NF user license reclaim response and returns the reclaimed user license to the slice manager.
Step S48: the slice manager sends an NF user permission allocation request to NF _ A-1 in the network slice 1, and adds 5 universal user permission to NF _ A-2.
Step S49: the NF _ A-1 in the network slice 1 returns NF user permission allocation response, and confirms that 5 ten thousand user permissions are added.
The method for sharing the NF user permission among the network slices disclosed by the embodiment of the application has the advantages that the method can recycle or distribute the user permission of the target type NF in the corresponding network slice according to the use condition of the user permission of the target type NF in any network slice, namely, the load condition of the target type NF in any network slice, and further can recycle the user permission with larger surplus aiming at the target type NF so that the slice manager can subsequently have enough resources to distribute the corresponding user permission for the target type NF with the tense user permission resources, thereby realizing the sharing of the NF user permission among the network slices and greatly improving the use efficiency of the user permission.
Accordingly, an embodiment of the present application discloses a system for sharing NF user permissions between network slices, which is shown in fig. 5 and includes:
