Method and apparatus for reducing latency of streaming service by network slices parallel in wireless communication system

A streaming service client (SSC) node in a wireless communication system, the SSC node comprising:

• a transceiver;
• at least one processor;
• and
• memory storing instructions, when executed by the at least one processor, that cause the SSC node to:
• establish a connection with a streaming service provider (SSP) node via two types of services including enhanced mobile broadband (eMBB) and ultra reliable low latency (URLLC),
• receive, from the SSP node, first data corresponding to a content of a data stream via the eMBB, and second data via the URLLC, wherein the second data is metadata used for generating the content of the data stream when the first data is not able to be used,
• identify whether the first data is successfully received, and
• in case that the first data is not successfully received from the SSP node, generate the content of the data stream based on the second data,
• wherein, in case that the first data is successfully received from the SSP node, the first data corresponding to the content is used for a streaming service by the SSC node.
