Abstract
A method, a system, and a non-transitory storage medium are described in which an access and mobility management function (AMF) assignment service is provided. A network device receives an assignment policy for selecting an AMF from a group of available AMFs, wherein the assignment policy includes network slice priorities for available network slices in the RAN; stores the assignment policy; receives, during a registration procedure initiated by an end device, Network Slice Selection Assistance Information (NSSAI); identifies, from the NSSAI, multiple single-NSSAIs (S-NSSAIs); and selects, based on the assignment policy, an AMF for a highest priority S-NSSAI, of the multiple S-NSSAIs.
Claims20
A method comprising:
- receiving, by an access device of a radio access network (RAN), an assignment policy for selecting an access and mobility management function (AMF) from a group of available AMFs, wherein the assignment policy includes network slice priorities for available network slices in the RAN,
- receiving, by the access device, a connection request initiated by an end device, wherein the connection request includes Network Slice Selection Assistance Information (NSSAI);
- identifying, by the access device and from the NSSAI, multiple single-NSSAIs (S-NSSAIs);
- and
- selecting, by the access device and based on the assignment policy, an AMF for a highest priority S-NSSAI, of the multiple S-NSSAIs.
A system comprising:
- an access device of a radio access network (RAN) including a first processor to:
- receive an assignment policy for selecting an access and mobility management function (AMF) from a group of available AMFs, wherein the assignment policy includes network slice priorities for available network slices in the RAN,
- receive a connection request initiated by an end device, wherein the connection request includes Network Slice Selection Assistance Information (NSSAI),
- identify, from the NSSAI, multiple single-NSSAIs (S-NSSAIs), and
- select, based on the assignment policy, an AMF for a highest priority S-NSSAI, of the multiple S-NSSAIs.
A non-transitory computer-readable storage medium storing instructions executable by a processor of a network device, which when executed cause the network device to:
- receive an assignment policy for selecting an access and mobility management function (AMF) from a group of available AMFs, wherein the assignment policy includes network slice priorities for available network slices in a radio access network (RAN);
- receive, from an end device, Network Slice Selection Assistance Information (NSSAI);
- identify, from the NSSAI, multiple single-NSSAIs (S-NSSAIs);
- and
- select, based on the assignment policy, an AMF for a highest priority S-NSSAI, of the multiple S-NSSAIs.
