A method for providing for policy-based access and mobility management function (AMF) selection using network slice selection assistance information (NSSAI) availability information obtained from an NSSAI availability service includes, at a network slice selection function (NSSF) including at least one processor, obtaining, from an NSSAI availability service, NSSAI availability information regarding a plurality of AMFs. The method further includes receiving, from a first AMF, a network slice selection request specifying a network slice service requested by a user equipment (UE). The method further includes generating, based on the NSSAI availability information and the network slice service requested by the UE, a prioritized list including an identity of at least one AMF for supporting the network slice service. The method further includes communicating the prioritized list to the first AMF.

A method for providing reduced signaling Internet of things (IoT) device monitoring includes steps performed in a combined and service capability exposure function (SCEF) and Diameter signaling router (DSR) including at least one processor. The method includes receiving Diameter signaling containing IoT device information. The method further includes using the IoT device information to automatically provision an IoT device information database. The method further includes receiving a monitoring subscription request. The method further includes extracting the IoT device information from the IoT device information database. The method further includes using the IoT device information to respond to the monitoring subscription request.

A method for Diameter signaling message external identifier address resolution and routing includes receiving a Diameter signaling message, decoding the Diameter signaling message and determining that an external identifier attribute value pair (AVP) is present in the Diameter signaling message. The method further includes decoding contents of the external identifier AVP, performing a lookup in a domain table using a domain identifier component of the external identifier AVP and locating an entry corresponding to the domain identifier component, determining whether a local identifier table is configured for the domain identifier component, performing a lookup in a local identifier table using a local identifier component of the external identifier AVP, populating at least one Diameter routing AVP of the Diameter signaling message with Diameter routing information obtained from the lookup in the domain table or the lookup in the local identifier table, and routing the Diameter signaling message using the Diameter routing information.

Methods, systems, and computer readable media for using access point name (APN) independent subscriber bindings. In some examples, a method is performed by a Diameter signaling router (DSR) for a telecommunications network. The method includes receiving, from a policy related node, a policy related message including a subscriber identifier associated with a subscriber; determining that the policy related message lacks APN information; after determining that the policy related message lacks APN information, using the subscriber identifier and preconfigured APN information to generate or identify a binding between the subscriber and a policy and charging rules function (PCRF) server of a pool of PCRF servers, or using the subscriber identifier to identify a first bound policy and charging rules function (PCRF) server of a pool of PCRF servers; and sending, to the identified PCRF server, the policy related message received from the policy related node.
