1. An information processing method for a Network Data Analytics Functions (NWDAF), comprising:
obtaining information of a slice;
determining, in accordance with the information of the slice, at least one of an analysis result related to the quantity of User Equipments (UEs) in the slice or an analysis result related to the quantity of Protocol Data Unit (PDU) sessions in the slice; and
transmitting at least one of the analysis result related to the quantity of UEs or the analysis result related to the quantity of PDU sessions to a target network element;
wherein the information processing method further comprises:
when the quantity of UEs in the slice reaches a maximum value or the quantity of PDU sessions in the slice reaches a maximum value, transmitting at least one of the analysis result related to the quantity of UEs or the analysis result related to the quantity of PDU sessions to instruct the target network element to start a congestion control mechanism,
wherein the target network element is a Policy Control Function (PCF), a Network Slice Selection Function (NSSF), or a Network Slice Quota (NSQ), and transmitting at least one of the analysis result related to the quantity of UEs or the analysis result related to the quantity of PDU sessions to instruct the target network element to start the congestion control mechanism comprises:
when the quantity of UEs in the slice reaches the maximum value or the congestion control indicator has been received, instructing the target network element to transmit a first notification message to an Access and Mobility Management Function (AMF), the first notification message being used to indicate that the quantity of UEs in the slice has reached the maximum value or Single Network Slice Selection Assistance Information (S-NSSAI) congestion occurs;
when the quantity of UEs in the slice is smaller than the maximum value, instructing the target network element to transmit a second notification message to the AMF, the second notification message being used to indicate that the quantity of UEs in the slice has not reached the maximum value or an S-NSSAI congestion is stopped, or,
wherein the target network element is a Policy Control Function (PCF), a Network Slice Selection Function (NSSF), or a Network Slice Quota (NSQ), and the starting the congestion control mechanism comprises:
when the quantity of PDU sessions in the slice has reached the maximum value or the congestion control indicator has been received, instructing the target network element to transmit a third notification message to the AMF or a Session Management Function (SMF), the third notification message being used to indicate that the quantity of PDU sessions in the slice has reached the maximum value or an S-NSSAI congestion occurs;
when the quantity of PDU sessions in the slice is smaller than the maximum value, instructing the target network element to transmit a fourth notification message to the AMF or SMF, the fourth notification message being used to indicate that the quantity of UEs in the slice has not reached the maximum value or an S-NSSAI congestion does not occur.
