Abstract: An embodiment includes receiving at a network node associated with a mobile core network an authorization request from a network device, wherein the authorization request is received via an untrusted network; subsequent to the receiving, performing at the network node authorization of the network device; subsequent to the receiving, determining a preferred network access node for the network device, wherein the determining comprises accessing a node selection information repository containing static and dynamic information related to network access nodes and network access node groupings and wherein the static and dynamic information comprises at least one of resource usage, location, availability of mobility anchors, proximity of mobility anchors, handover opportunities, resiliency class, and time of day; and providing to the network device an initial authorization response comprising a response to the received authorization request, wherein the initial authorization response identifies the determined preferred network access node.

Abstract: A network function (NF) profile repository function (NPRF) is provided to receive, for each one of a plurality of NF instances of a plurality of different NF types, information associated with the NF instance and store the information in memory. The NPRF may then also receive, from an NF repository function (NRF), a message which indicates a request for information associated with one or more NF instances of an indicated NF type. In response, the NPRF may retrieve, from the memory based on the indicated NF type, information associated with the one or more NF instances. The NPRF may send, to the NRF, a message which indicates a response to the request, where the response includes retrieved information associated with the one or more NF instances.

Abstract: In one embodiment, a method comprises obtaining, by a first network element comprising processing logic, notification of a plurality of events associated with a plurality of communication sessions, wherein the events include at least one of a mid-session event or an end-session event, wherein the plurality of events are communicated to a routing agent using a first communication protocol by a plurality of second network elements; receiving, by the first network element, a request via a second communication protocol for a first communication session to be established for a client computing device; selecting, by the first network element, one or more network elements from the second network elements for the communication session based on the at least one of a mid-session or an end-session event; and communicating, by the first network element, identification information of the one or more network elements selected for use in the first communication session.

Abstract: An example method is provided in one example embodiment and may include provisioning a user equipment (UE) with a list comprising one or more locations at which the UE is to report its location; reporting a location of the UE when the location is identified in the list; provisioning the UE with one or more access network selection policy based on the reported location of the UE; and applying at least one access network selection policy at the UE based on the location of the UE. The list comprising the one or more locations can be sent to the UE from an Access Network Discovery and Selection Function (ANDSF) server after the UE reports its location to the ANDSF server. The one or more access network selection policies can be permanent type and/or temporal type policies.
