Communication method and apparatus for configuring multicast QoS parameter

A communication apparatus, comprising:

• a memory storing instructions;
• and
• at least one processor in communication with the memory, the at least one processor configured, upon execution of the instructions, to perform the following steps:
• receiving a target multicast quality of service (QOS) parameter corresponding to a first multicast group from a multicast session management function network element, the target multicast QoS parameter comprising an allocation and retention priority (ARP), the target multicast QoS parameter being used for configuring a QoS parameter corresponding to the first multicast group, and the unicast session management function network element is a unicast session management function network element corresponding to the first multicast group;
• and
• configuring, based on the target multicast QoS parameter, a QoS parameter of a unicast session corresponding to the first multicast group.
