The following describes a method for managing a network slice according to an embodiment of the present invention, with reference to the communication system shown in fig. 1 and the management apparatus 100 for a network slice shown in fig. 2.
As shown in fig. 3, a method for managing network slices provided in an embodiment of the present invention includes:
s301, the network slice management device 100 acquires target information for each network slice in the administrative area.
Specifically, the network slice management device 100 acquires target information that each base station in the jurisdiction area monitors the network slice in the base station. The network slice management apparatus 100 periodically acquires target information of each network slice in the jurisdiction area from the base station in the jurisdiction area.
The target information comprises a service type, a current rate, a current resource utilization rate and a current accessed user number. The current rate is specifically the current highest rate. The current rate can be obtained by conversion according to parameters such as the current channel quality, the number of available resources of the current slice, the number of antennas and the like. The current resource utilization ratio is specifically a Resource Block (RB) resource utilization ratio of a current resource block. The current resource utilization may be replaced by the number of currently occupied PBs. The number of users that have currently accessed may also be referred to as the number of terminals (UEs) that have currently accessed.
S302, the network slice management apparatus 100 determines a decision factor value for each network slice according to the target information of each network slice.
Wherein the decision factor value of the network slice is used to represent the current service level status of the network slice. The lower the decision factor value of the network slice is, the higher the current service level of the network slice is.
Alternatively, the decision factor value of the network slice may be determined according to the formula "Threshold Pue _ num _ PRate _ PRB". Wherein Threshold is a decision factor value of the network slice, and Pue _ num is a ratio of a current accessed user number of the network slice to a user number of an SLA subscription. PRate is the ratio of the current rate of the network slice to the rate of SLA subscription. The PRB is the ratio of the current resource utilization rate of the network slice to the SLA signed resource utilization rate. Under the condition that the current resource utilization rate is replaced by the number of the currently occupied PBs, the PRB is the ratio of the number of the currently occupied PBs of the network slice to the number of the SLA signed PBs.
S303, the management device 100 of the network slice sends a first message to the base station where the network slice is located when the decision factor value of the network slice is higher than the threshold value.
Correspondingly, after receiving the first message, the base station where the network slice is located deactivates the network slice and no longer provides the service of the network slice service type.
Wherein the first message is used for instructing the base station to deactivate the network slice and no longer provide the service of the network slice service type. A network slice having a decision factor value above a threshold value indicates that the current service level of the network slice has failed to satisfy the SLA.
The threshold value may be preset, for example, the threshold value may be set to 1. The threshold value may also be determined by simulation evaluation. The threshold value may be represented by cthreshold 1.
The threshold values of the network slices of different service types may be the same or different. The threshold values of different network slices under the same base station may be the same or different.
Illustratively, cell 1 and cell 2 exist in the jurisdiction of the management apparatus 100 for network slices, and there is one network slice of service type 1 in each of cell 1 and cell 2. The terminal 1 located in the administrative area of the network slice management apparatus 100 may access the cell 1 to perform the service of the service type 1, and may access the cell 2 to perform the service of the service type 1. The network slice management apparatus 100 obtains target information of a network slice of the service type 1 in the cell 1, determines a decision factor value of the network slice according to the target information of the network slice, and then determines that the decision factor value of the network slice is greater than a threshold value (i.e., the network slice cannot satisfy the SLA), then the base station where the network slice is located sends a first message. Correspondingly, after the base station of the cell 1 receives the first message, the network slice of the service type 1 in the cell 1 is deactivated and the service of the service type 1 is not provided. At this time, the terminal 1 located in the administrative area of the network slice management apparatus 100 cannot access the cell 1 to perform the service of the traffic type 1, but can access the cell 2 to perform the service of the traffic type 1.
As can be seen from the above steps (S301-S303), in the embodiment of the present invention, by sending a message to the base stations where the network slices that do not satisfy the SLA (i.e., the network slices whose decision factor values are higher than the threshold value) are located, the base stations deactivate the network slices that do not satisfy the SLA, so that the network slices in the cell all can satisfy the SLA. Therefore, the situation that the terminal uses the network slice which does not meet the SLA after accessing the cell is avoided, and the problem of how to avoid using the network slice which does not meet the SLA after the terminal accesses the cell is solved.
With reference to fig. 3, as shown in fig. 4, the method for managing network slices according to the embodiment of the present invention may further include:
s304, the management device 100 of the network slice sends a second message to the base station where the network slice is located when the decision factor value of the network slice is smaller than the threshold value.
Correspondingly, after receiving the second message, the base station where the network slice is located activates the network slice and provides the service of the service type of the network slice. And if the network slice is in the activated state, the base station where the network slice is located does not repeatedly activate the network slice after receiving the second message.
Wherein the second message is used for instructing the base station to activate the network slice and provide the service of the network slice service type.
Optionally, the target information may further include an activation status of the network slice, in this case. S304 may be: the management apparatus 100 of the network slice transmits a second message to the base station where the network slice is located when the decision factor value of the network slice is smaller than the threshold value and the network slice is in a deactivated state.
Alternatively, in a case that the decision factor value of the network slice is equal to the threshold value, the management device 100 of the network slice may execute S303 and may also execute S304. The embodiment of the present invention is not limited thereto.
S305, the network slice management apparatus 100 refuses to send the first message to the base station where the first target network slice is located when the decision factor values of the network slices of the same service type in the jurisdiction area are all higher than the threshold value.
The first target network slice is N network slices with minimum decision factor values in the network slices of the same service type, and N is a positive integer. For example, N may be 1.
It can be seen that at least one of the network slices of the same service type in the jurisdiction can be in an activated state through S305, so as to avoid a situation that all the network slices of the same service type in the jurisdiction are deactivated, which results in that the user cannot use the service of the service type in the jurisdiction.
Optionally, under the condition that the decision factor values of the network slices of the same service type in the jurisdiction area are all higher than the threshold value, the threshold value may also be adjusted upwards, and it is determined whether the decision factor values of the network slices of the service type are all higher than the adjusted threshold value. If the judgment factor values of the network slices of the service type are all higher than the threshold value after the adjustment, the threshold value is continuously adjusted up until the network slices of the service type with the judgment factor values lower than the threshold value after the adjustment exist. If the network slices of the service type have network slices lower than the threshold value after being adjusted, a second message is sent to the base station where the network slices are located, and a first message is sent to the base stations where the other network slices of the service type are located.
S306, the management device 100 of network slices sends a first message to the base station where the second target network slice is located when the decision factor values of the network slices of the same service type in the jurisdiction area are all lower than the threshold value.
The second target network slice is M network slices with the maximum decision factor value in the network slices of the same service type, and M is a positive integer. M may be the same as or different from N.
The scheme provided by the embodiment of the invention is mainly introduced from the perspective of a method. To implement the above functions, it includes hardware structures and/or software modules for performing the respective functions. Those of skill in the art will readily appreciate that the present invention can be implemented in hardware or a combination of hardware and computer software, with the exemplary elements and algorithm steps described in connection with the embodiments disclosed herein. Whether a function is performed as hardware or computer software drives hardware depends upon the particular application and design constraints imposed on the solution. Skilled artisans may implement the described functionality in varying ways for each particular application, but such implementation decisions should not be interpreted as causing a departure from the scope of the present invention.
The embodiment of the present invention may perform the division of the functional modules for the management apparatus 100 of the network slice according to the above method example, for example, each functional module may be divided for each function, or two or more functions may be integrated into one processing module. The integrated module can be realized in a hardware mode, and can also be realized in a software functional module mode. It should be noted that, the division of the modules in the embodiment of the present invention is schematic, and is only a logic function division, and there may be another division manner in actual implementation.
