And receiving a network slice reflection DRB indication sent by the access network element to the user terminal.
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 (maximum aggregate bit rate) at the user level, to the user terminal, and of course, the Slice QoS parameter information may be other parameters that can characterize the Slice performance requirements, or Slice profile.
In a specific embodiment, a 5G access network element NG-RAN (Next Generation Radio Access Networks, next generation radio access network) node forwards a registration admission message (Registration Accept), or a registration area update admission message (RAU Accept, registration Area Update Accept), or an initial user context setup message (Initial UE Context Setup Request) from a 5G core network element AMF (Authentication Management Function ) to the user terminal, where the messages carry slice QoS parameters.
In another embodiment, the 5G access network element NG-RAN node carries slice QoS parameter information in RRC (Radio Resource Control ) signaling, such as RRC connection reconfiguration signaling (RRC Connection Reconfiguration) or RRC connection recovery signaling (RRC Connection Resume), which it sends to the user terminal.
The slice QoS parameter information is user-level slice QoS parameter information. The method and the device enable the user to execute resource scheduling and isolation of the user terminal side slice, and mainly control the user-level slice uplink service. For example, based on the priority of the network slices, higher MAC ((Media Access Control, media access control) scheduling priority may be considered, or when considering inter-slice resource flow, the 5G access network element may give higher resource sharing rights to high priority slices.
For example, the slice QoS parameter information includes a maximum rate of network slices, such as a cumulative maximum bit rate at a 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 guarantee rate, so that when the user terminal collides with the resource, each slice is guaranteed to meet the basic flow requirement by a certain isolation protection and admission control means.
The slice QoS parameter information can also be used as a smoothing window of a network slice, and is used for assisting in calculating the maximum rate and the guaranteed rate of the network slice, which is a period of related calculation, and is used for guaranteeing quality monitoring of slices with different time granularities, and the smaller the smoothing window is, the finer the quality monitoring is.
The slice QoS parameter information may further include a network slice allocation reservation priority ARP (Address Resolution Protocol ), including preemption capability (pre-emption capability) and preemption vulnerability (pre-emption vulnerability) indicators, where the stronger the preemption capability, the more important the current service request, and in the case of limited resources, the more likely it is to preempt resources of other low priority services for the current service request; the more fragile the fragile index is preempted, the more easily the resources enjoyed by the current service are preempted by new high priority service requests. The transmission of the network slice ARP information enables the user terminal to decide on the slice resource flow according to the priority of the slice traffic.
The slice QoS parameter information may also include a network slice reflection quality of service indication RQI, which is a slice level parameter. And when the indication is 1, representing that all QoS service flows of the user terminal adopt QoS reflection, and referring to the mapping mode of the same IP service flow from the information from the core network, namely the mapping of the uplink IP service flow to the QoS service flow. The access network element may refer to a decision, whether the mapping of the uplink QoS traffic flow to the DRB (Data Radio Bearer, data bearer) refers to the mapping mode of the downlink same QoS traffic flow, i.e. whether the access network also adopts the service quality reflection mode.
The slice QoS parameter information may also include network slice notification control information, which reflects the situation that, for a session of a specified slice, the user terminal needs to feed back performance monitoring to the network side periodically or when the user terminal needs are difficult to be satisfied.
