Abstract
Disclosed are a slice processing method and apparatus, a storage medium, and a processor. The method includes: obtaining, by a first network side device, a first handover request sent from a source base station, and determining a handover behavior based on slice information.
Claims20
A slice processing method, comprising:
- obtaining, by a network side device, a handover request sent from a source base station associated with a packet-data-unit (PDU) session to be handed over to a target base station, wherein the PDU session is associated with a second slice and the target base station is associated with at least a first slice, and wherein the handover request carries slice information and a Quality of Service (QoS) attribute set for at least one QoS flow of the PDU session;
- identifying, by the network side device, that the first slice is different from the second slice by determining that a first slice identifier of the first slice is different from a second slice identifier of the second slice;
- selecting, by the network device and based on the slice information and the QoS attribute set, a handover behavior, wherein the selecting the handover behavior comprises selecting one of:
- remapping the second slice onto a different slice that is in a same slice-group as the first slice supported by the target base station,
- falling-back to a default slice supported by the target base station, and
- determining that the requested handover is not supported;
- and
- performing the selected handover behavior.

A network side device comprising:
- one or more processors, and memory storing operational instructions that, when executed by at least one of the one or more processors, cause the network side device to:
- obtain a handover request sent from a source base station associated with a packet-data-unit (PDU) session to be handed over to a target base station, wherein the PDU session is associated with a second slice and the target base station is associated with at least a first slice, and wherein the handover request carries slice information and a Quality of Service (QoS) attribute set for at least one QoS flow of the PDU session;
- identify that the first slice is different from the second slice by determining that a first slice identifier of the first slice is different from a second slice identifier of the second slice;
- select, based on the slice information and the QoS attribute set, a handover behavior, wherein the selection of the handover behavior comprises selection of one of:
- remapping the second slice onto a different slice that is in a same slice-group as the first slice supported by the target base station,
- falling-back to a default slice supported by the target base station, and
- determining that the requested handover is not supported;
- and
- perform the selected handover behavior.
