1. A method of a first network entity performing a session management function (SMF) in a communication system, comprising:
obtaining a first filter for a first direction and a second filter for a second direction, the first filter and the second filter being associated with an application;
identifying whether the first filter is a bidirectional filter based on a result of comparing the first filter and the second filter;
identifying whether a second network entity performing a user plane function (UPF) supports a function of obtaining the second filter, based on the first filter being identified as the bidirectional filter; and
transmitting, to the second network entity, a first message comprising the first filter and information indicating that the first filter is the bidirectional filter, based on identifying that the second network entity supports the function of obtaining the second filter.
