1. A method performed by a network data analytics function (NWDAF) in a communication system, the method comprising:
receiving, from a policy control function (PCF), a message including a request for radio access analytics information on a terminal in a specific area, wherein the request is associated with a policy configured between the PCF and an operation, administration, and maintenance (OAM);
obtaining, usage information related to a service used by the terminal in the specific area and network information related to a frequency band for each radio access technology (RAT) supported in the specific area, based on the message;
identifying a correlation for the specific area based on the service used by the terminal and the frequency band for each RAT;
generating the radio access analytics information based on the identified correlation; and
transmitting, to the PCF, the generated radio access analytics information,
wherein the radio access analytics information is used to configure a radio/frequency selection priority (RFSP) index value indicating a specific frequency band for a RAT, and
wherein the specific frequency band for the RAT is for the service in the specific area.
