Embodiment Construction

[0044] figure 1 is a block diagram illustrating an exemplary 5G system network architecture. exist figure 1 , the network includes an NRF 100 and a Service Communication Agent (SCP) 101 . As described above, the NRF 100 may maintain a profile of available producer NF service instances and the services they support, and allow consumer NFs or SCPs to subscribe and be notified of registrations of new / updated producer NF service instances. SCP101 can also support service discovery and selection of producer NFs. Additionally, SCP 101 can load balance connections between consumer NFs and producer NFs.

[0045] NRF 100 is a repository of NF profiles. In order to communicate with the producer NF, the consumer NF or SCP must obtain the NF profile from the NRF 100. A NF profile is a JavaScript Object Notation (JSON) data structure defined in 3GPP TS 29.510. The NF profile definition includes at least one of a fully qualified domain name (FQDN), an Internet Protocol (IP) version 4 ...

Abstract

A method for providing 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 NSSAI availability information regarding a plurality of AMFs from the NSSAI availability service. The method also includes receiving, from the first AMF, a network slice selection request specifying a network slice service requested by a user equipment (UE). The method further includes generating a prioritized list based on the NSSAI availability information and the network slicing service requested by the UE, the list including an identity of at least one AMF for supporting the network slicing service. The method also includes transmitting the prioritized list to the first AMF.

Description

[0001] priority claim [0002] This application claims priority to US Patent Application Serial No. 16 / 676,006, filed November 6, 2019, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The topics described in this article relate to network slicing. More particularly, the subject matter described herein relates to methods, systems, and computer-readable media for providing policy-based AMF selection using NSSAI availability information. Background technique [0004] In 5G telecom networks, network nodes that provide services are called producer network functions (NFs). A network node that consumes a service is called a consumer NF. A network function can be a producer NF and a consumer NF, depending on whether it consumes or provides a service. [0005] A given producer NF may have many service endpoints, where a service endpoint is a combination of IP address and port number on the network node hosting the producer NF. ...
