Abstract: The present disclosure provides methods and apparatuses for provisioning a bidirectional filter. In some embodiments, a method of a first network entity performing a session management function (SMF) in a communication system includes obtaining a first filter for a first direction and a second filter for a second direction that are 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 including 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.
