Thus, a slice-by-slice control policy of a ue can be introduced, for example, when the access network element allocates a resource pool shared by multiple slices to the ue, the ue supporting multiple slices (multiple slices) can allocate available resources of each slice based on the received per-slice policy (per slice policy), so as to achieve maximum network resource sharing on the basis of slice isolation.

And receiving a network slice reflection DRB indication sent to the user terminal by the access network element.
In an embodiment of the present invention, as shown in fig. 3, a method for processing a network slice includes:
the access network element sends Slice QoS parameter information, such as Slice-AMBR (aggregate maximum aggregated bit rate) at the user level, to the user terminal, and of course, the Slice QoS parameter information may also be other parameters capable of characterizing Slice performance requirements or Slice profile (policy).
In a specific embodiment, a NG-RAN (Next Generation Radio access network) node of a 5G access network element forwards a Registration Accept message (Registration Accept), a Registration Area Update Accept message (RAU Accept), or an Initial UE Context Setup message (Initial UE Context Setup Request) sent from an AMF (authentication management Function) of the 5G core network element to a UE, where the Registration Accept message, the Registration Area Update Accept message, or the Initial UE Context Setup message carries a slice QoS parameter.
In another specific embodiment, the 5G access network element NG-RAN node carries the slice QoS parameter information in an RRC (Radio Resource Control) signaling, such as an RRC Connection Reconfiguration signaling (RRCConnection Reconfiguration) or an RRC Connection recovery signaling (RRC Connection Resource), sent by the NG-RAN node to the user terminal.
The slice QoS parameter information is user-level slice QoS parameter information. The user can execute resource scheduling and isolation of the user terminal side slice, and the control of the user level slice uplink service is mainly performed. For example, based on the priority of the network slice, a higher MAC (Media Access Control) scheduling priority may be considered, or when considering resource flow between slices, the 5G Access network element may give a higher resource sharing right to the high-priority slice.
For example, the slice QoS parameter information includes a maximum rate of the network slice, such as a cumulative maximum bit rate at the slice level, so that the user terminal can perform admission control, flow control and scheduling control of network slice users/services based on the received maximum bit rate information.
For another example, the slice QoS parameter information includes a network slice guaranteed rate, so that when the user terminal has resource conflict, each slice is guaranteed to meet the basic traffic demand by a certain isolation protection and admission control means.
The slice QoS parameter information may also be a smooth window of the network slice, which is used to assist the computation including the maximum rate and guaranteed rate of the network slice, and is a period of the related computation, which is used to guarantee quality monitoring of slices of different time granularities, and the smaller the smooth window, the finer the quality monitoring.
The slice QoS parameter information may further include an Address Resolution Protocol (ARP), which includes a preemption capability (pre-preemption capability) and a preemption vulnerability (pre-preemption vulnerability) index, where the stronger the preemption capability is, the more important the current service request is, and under the condition of resource limitation, the more likely it is to preempt the resources of other low-priority services for the current service request to use; the more vulnerable the preemption becomes, the more resources the current service enjoys are preempted by new high priority service requests. Therefore, the transmission of the network slice ARP information enables the user terminal to decide the flow of slice resources according to the priority of the slice service.
The slice QoS parameter information may also include a network slice reflection quality of service indication RQI, a parameter at the slice level. The value of the network slice reflection service quality indication is 0 or 1, when the indication is 1, the representation is that all QoS service flows of the user terminal adopt service quality reflection, and the information from the core network, namely the mapping from the uplink IP service flow to the QoS service flow, refers to the mapping mode of the same downlink IP service flow. The access network element may refer to the decision, whether mapping from the uplink QoS traffic to a DRB (Data Radio Bearer) refers to a mapping manner of the same downlink QoS traffic, that is, whether the access network also adopts a quality of service reflection manner.
The slice QoS parameter information may also include network slice notification control information, which reflects the situation that the user terminal needs to feed back performance monitoring to the network side periodically or when the user terminal requirements are difficult to meet for a specified slice session.
An embodiment of the present invention further provides an access network element, as shown in fig. 4, including a processor 31 and a transceiver 32,
the transceiver 32 is configured to send the slice quality of service QoS parameter information to the user terminal.
In this embodiment, the access network element interacts with the user terminal, so that the user terminal can receive slice QoS parameter information from the network, so as to perform QoS control according to the slice QoS parameter information. Thus, a slice-by-slice control policy of a ue can be introduced, for example, when the access network element allocates a resource pool shared by multiple slices to the ue, the ue supporting multiple slices (multiple slices) can allocate available resources of each slice based on the received per-slice policy (per slice policy), so as to achieve maximum network resource sharing on the basis of slice isolation.
