Abstract
Systems, methods, and devices can be utilized for policy control function (PCF) fallback during the set up of a session utilizing a 5th Generation (5G) core network. An example method includes receiving, from a session management function (SMF), a request for a policy corresponding to a session. The request includes a first policy identifier corresponding to a first policy control function (PCF). The example method further includes determining that the first PCF is unavailable, generating a modified request by replacing the first policy identifier with a second policy identifier in the request. The second policy identifier corresponds to a second PCF. The example method also includes transmitting, to the second PCF, the modified second request.
