A network device may include a memory storing instructions and processor configured to execute the instructions to receive a request for a session management (SM) policy association in relation to establishment of a packet data unit (PDU) session for a particular user equipment (UE) device; requesting, from a second network device, access and mobility (AM) policy decisions pertaining to the UE device; receiving AM policy decisions from the second network device, and creating the SM policy association based on at least the received AM policy decisions. The request for SM policy association includes an identifier associated with the second network device. The processor may be further configured to determine whether the network device is the same as the second network device based on the identifier; and transmit a request to the second network device when it is determined that the second network device is not the same as the first network device.
