In a specific embodiment of the present invention, as shown in FIG. 3, the processing method of network slicing includes:

The access network element sends slice QoS parameter information to the user terminal, such as user-level Slice (slice)-AMBR (AggregationMaximumBitRate, maximum aggregate bit rate), of course, the slice QoS parameter information can also be other parameters that can represent slice performance requirements , or slice profile (strategy).

In a specific embodiment, the 5G access network element NG-RAN (Next Generation Radio AccessNetworks, next-generation radio access network) node (node) forwards the information sent by the 5G core network element AMF (Authentication Management Function, authentication management function) A registration accept message (Registration Accept), or a registration area update accept message (RAU Accept, Registration Area Update Accept), or an initial user context setup message (Initial UE Context Setup Request) is sent to the user terminal, and these messages carry slice QoS parameters.

In another specific embodiment, the 5G access network element NG-RAN node sends RRC (Radio Resource Control, radio resource control) signaling to the user terminal, such as RRC connection reconfiguration signaling (RRCConnection Reconfiguration) or RRC The connection resume signaling (RRC Connection Resume) carries slice QoS parameter information.

The slice QoS parameter information is user-level slice QoS parameter information. It enables users to perform resource scheduling and isolation of slices on the user terminal side, and mainly controls slice uplink services at the user level. For example, based on the priority of network slicing, a higher MAC ((Media Access Control, Media Access Control) scheduling priority can be considered, or when considering resource flow between slices, 5G access network elements will give high priority Slices have higher resource sharing rights.

For example, the slice QoS parameter information includes the maximum rate of the network slice, such as the cumulative maximum bit rate at the slice level, so that the user terminal can perform network slice user/service admission control, flow control, and scheduling control based on the received maximum bit rate information.

For another example, the slice QoS parameter information includes the guaranteed rate of the network slice, so that when the resource conflicts, the user terminal can ensure that each slice meets the basic traffic demand through certain isolation protection and admission control means.

Slice QoS parameter information can also be used as the smoothing window of the network slice, which is used to assist in the calculation of the maximum rate and guaranteed rate of the network slice. It is a cycle of related calculations and used to ensure slice quality monitoring at different time granularities. Monitoring is finer.

Slice QoS parameter information may also include network slice allocation retention priority ARP (Address Resolution Protocol, Address Resolution Protocol), including pre-emption capability (pre-emption capability) and pre-emption vulnerability (pre-emption vulnerability) indicators, the stronger the preemption capability, the current The more important the service request is, the more likely it is to preempt the resources of other low-priority services for the current service request when resources are limited; the more vulnerable the preemptive index is, the more resources the current service enjoys. It is easy to be preempted by new high-priority business requests. Therefore, the transfer of network slicing ARP information enables user terminals to decide the flow of slicing resources according to the priority of slicing services.

The slice QoS parameter information may also include a network slice reflection quality of service indicator RQI, which is a slice-level parameter. The value of the network slicing reflection quality of service indication is 0 or 1. When the indication is 1, it means that all QoS service flows of the user terminal use quality of service reflection, and the information from the core network, that is, the uplink IP service flow For the mapping to the QoS service flow, refer to the mapping method of the same downlink IP service flow. The network element of the access network can refer to the decision whether to map the upstream QoS service flow to the DRB (Data Radio Bearer, data bearer), whether to refer to the mapping method of the same downlink QoS service flow, that is, whether the access network also adopts the quality of service reflection method .

The slice QoS parameter information may also include network slice notification control information, which reflects that for a session of a specified slice, the user terminal needs to feed back the performance monitoring situation to the network side periodically or when the demand of the user terminal is difficult to be met.
