Detailed Description
The present disclosure now will be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the disclosure are shown. The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
The terms "first", "second", and the like are used hereinafter only for descriptive distinction and have no other special meaning.
The concept of network slice is defined in the 5G standardization, and may be used to divide a physical network of an operator into a plurality of virtual networks, implement configuration and management of end-to-end personalized resources, and provide different levels of service quality, such as rate, reliability, time delay, etc., for each virtual network, i.e., network slice.
Fig. 1 is a schematic flow chart diagram of an embodiment of a network slice processing method according to the present disclosure, as shown in fig. 1:
In step 102, the ran-side device sets a slice priority for the network slice based on the configuration information, and stores the slice priority in the identification information corresponding to the network slice. The identification information may be a variety of existing identification information.
In case of overload or congestion of the network, the network side is required to preferentially allocate limited radio resources to some more important network slices, i.e. high-priority network slices. Currently, a network slice on the RAN side is mapped to different 5QI levels for users of different slices through an OSS (Operation Support System) System, and the network slice on the RAN side implements different priorities during scheduling, so that the RAN distinguishes between L1/L2 configuration and resource scheduling to implement resource isolation, where L1/L2 is an interface protocol layer of LTE.
Due to the large number of QoS (Quality of Service) flows, operators design and customize a large number of 5QI priority precedence configurations, and the introduction of any new network slice affects the defined priority order. The 5QI is identified by 8 bits, and there are only 128 possible 5QI values at most. For the number of network slices and the service types in the 5G system, the slice priority achieved by using 5QI is far from meeting the requirement of the number of network slices in the future.
The network slice processing method disclosed by the invention provides a concept of slice priority and a technical scheme of how to configure and manage the slice priority.
In one embodiment, a RAN-side device locally obtains a first s-NSSAI (Single Network Slice Selection Assistance Information) for identifying a Network Slice, and the RAN-side device adds a Slice priority to the first s-NSSAI.
The core network side device configures slice priorities of network slices in a TA (tracking area) area, generates configuration information, and transmits the configuration information to the RAN side device. The core network side equipment locally obtains a second s-NSSAI used for identifying the network slice, and adds slice priority in the second s-NSSAI, wherein the slice priorities of the network slices in the same TA area are the same.
The core network comprises a 5G core network and the like; the Radio Access Network includes NG-RAN (NG Radio Access Network, next generation Radio Access Network), etc.; the wireless side equipment comprises a gNB, an eNB and the like, wherein the gNB is an NR base station, and the eNB (Evolved NodeB) is an LTE base station; the network side device includes an AMF (Session Management Function) and the like. Slice priority is added to an ID list of network slices maintained by an AMF of a core network, and slice priority information is issued to nodes of an access network, namely gNB or eNB and the like. The gbb, eNB, or the like allocates radio resources and performs other L1/L2 resource allocation for each slice using the priority information.
For example, both the gNB side and the AMF maintain a supported NSSAI list, the NSSAI list includes a plurality of s-NSSAIs, and for each s-NSSAI, a slice priority needs to be configured, and the slice priority may be configured by the 5G core network or may be preconfigured by the operator.
For 5G core network configuration: if the slice priority configuration of all gnbs within a certain AMF control area is the same, the priority of the slices can be uniformly configured by 5G. The priority of each slice in a certain TA area is configured through 5GC, and the supported slices in the same registration area are the same and the priority among the slices is the same. Configured by an operator OAM system: the priority of each slice may be determined by the gNB, and if the slice priority of a certain gNB requires special configuration, the configuration is performed through OAM.
In one embodiment, an OAM (Operation Administration and Maintenance) system configures slice priorities of network slices and generates configuration information, which is sent to the RAN-side device. The OAM system sets a user level corresponding to the user, and the OAM system sets a slice priority of the network slice corresponding to the user based on the user level.
For example, the operator ranks the users, such as high, medium, and low level users, each of which corresponds to a network slice, and defines the slice priority, where the high level user has a higher priority (priority 1), the low level user has a lower priority (priority 3), and the medium level user has a middle priority (priority 2).
The OAM system configures a plurality of network slices based on user attributes of users, acquires a plurality of areas to which the plurality of network slices are applied, and sets slice priority of each network slice in the plurality of network slices in each area; wherein each network slice has a different slice priority in a different region.
For example, the operator sets a network slice for user attributes, for example, a campus user slice and a common user slice are divided; in the campus area, the priority of the campus user slice is higher than that of the common user slice, and in other areas, the priority of the campus user slice is the same as that of the common user slice; configuring the campus slice priority of a campus area to be 1, the priority of a common user to be 2, and the priorities of the campus slices and the common user slices in other areas to be 2 according to the configuration of a core network; through the configuration, the users of the campus slice in the campus area can preferentially allocate the wireless resources of the access network side.
Fig. 2 is a schematic flow chart of setting priority in an embodiment of a network slice processing method according to the present disclosure, as shown in fig. 2:
in step 201, the ran-side device receives configuration information sent by the core network device and the OAM system.
In step 202, if the core network device and the OAM both set slice priorities for the same network slice, the RAN-side device sets the slice priorities for the same network slice based on a preset priority setting rule.
The priority setting rule may be various. For example, the RAN-side device obtains the slice priority corresponding to the same network slice from the configuration information sent by the OAM system, and sets the slice priority as the slice priority of the same network slice. That is, in the case where both the 5G core network and the OAM system configure the slice priority of the network slice, the slice priority of the network slice depends on the configuration of the OAM system.
And the RAN side equipment realizes resource isolation among the network slices according to the slice priority information. In resource scheduling, RAN-side equipment first performs sequencing according to slice priorities, preferentially performs resource allocation of high-priority slices, and performs allocation according to the priority of QoS flow/DRB (Data Radio Bearer) in network slices of the same priority.
Fig. 3 is a schematic flowchart of resource allocation in an embodiment of a network slice processing method according to the present disclosure, as shown in fig. 3:
in step 301, the ran-side device sorts the network slices according to slice priorities, wherein the slice priority of a preceding network slice is higher than the slice priority of a following network slice.
In step 302, the ran-side device performs radio resource allocation and air interface resource allocation on the network slices based on the ranking, so as to implement resource isolation between the network slices. RAN side equipment realizes resource isolation among slices according to slice priority information, and the resource isolation includes L1/L2 configuration and scheduling, wherein a plurality of network slices with the same slice priority are distributed according to the priority of QoS flow or DRB.
The network slice processing method in the above embodiment defines a concept of slice priority, and unifies a processing principle between slices by an access network and a core network, so that a RAN side can implement resource isolation between slices according to slice priority information, including L1/L2 configuration, scheduling, and the like.
In one embodiment, the present invention provides a network slice processing system comprising: radio access network RAN-side equipment 41, core network setup 42 and OAM system 43. The RAN-side device 41 receives configuration information for configuring the slice priority of the network slice.
The RAN-side device 41 sets a slice priority for the network slice based on the configuration information, and stores the slice priority in the identification information corresponding to the network slice. For example, the RAN-side device 41 may locally obtain the first single network slice selection assistance information s-NSSAI for identifying the network slice, adding a slice priority in the first s-NSSAI. When performing resource scheduling, RAN-side device 41 obtains slice priority from identification information corresponding to a network slice, and performs resource allocation on the network slice based on the slice priority.
In one embodiment, the core network side device 42 configures slice priorities of network slices in the TA area and generates configuration information, and sends the configuration information to the RAN side device 41. The core network side device 42 locally obtains a second s-NSSAI for identifying the network slice, and adds a slice priority to the second s-NSSAI; wherein, the slice priorities of the network slices in the same TA area are the same.
In one embodiment, the OAM system 43 configures the slice priority of the network slice and generates configuration information, which is sent to the RAN-side device 41. The OAM system 43 sets a user level corresponding to the user, and sets a slice priority of a network slice corresponding to the user based on the user level.
OAM system 43 configures multiple network slices based on user attributes of the users; obtaining a plurality of areas to which a plurality of network slices are applied, and setting slice priority of each network slice in the plurality of network slices in each area; wherein each network slice has a different slice priority in a different region.
In one embodiment, RAN-side device 41 receives configuration information sent by core network device 42 and OAM system 43. If both the core network device 42 and the OAM system 43 set slice priorities for the same network slice, the RAN-side device 41 sets the slice priorities for the same network slice based on a preset priority setting rule. The RAN-side device 41 obtains the slice priority corresponding to the same network slice from the configuration information sent by the OAM system 43, and sets the slice priority as the slice priority of the same network slice.
The RAN-side device 41 orders the network slices according to the slice priority, wherein the slice priority of the preceding network slice is higher than the slice priority of the following network slice. RAN-side device 41 performs radio resource allocation and air interface resource allocation on the network slices based on the ranking, so as to implement resource isolation between each network slice; wherein a plurality of network slices having the same slice priority are allocated according to the priority of the QoS flow or the DRB.
