Abstract
A method, a device, and a non-transitory storage medium provide an optimized network function (NF) selection service for roaming. A first network device in a home network receives, from a second network device, a first discovery message, the first discovery message including a visited network identifier for a roaming session. The first network device matches the visited network identifier to a network identifier in a Session Management Function (SMF) profile. The first network device sends, to the second network device, a first identifier for a home SMF for the roaming session based on the visited network identifier.
Claims20
A method, comprising:
- receiving, by a first network device in a home network and from a second network device, a first discovery message, the first discovery message including a visited network identifier for a roaming session;
- matching the visited network identifier to a network identifier in a Session Management Function (SMF) profile;
- and
- sending, by the first network device and to the second network device, a first identifier for a home SMF (H-SMF) for the roaming session based on the visited network identifier.
One or more network devices, comprising:
- one or more processors configured to execute instructions to:
- receive, in a home network and from a second network device, a first discovery message, the first discovery message including a visited network identifier for a roaming session;
- match the visited network identifier to a network identifier in a Session Management Function (SMF) profile;
- and
- send, to the second network device, a first identifier for a home SMF (H-SMF) for the roaming session based on the visited network identifier.
A non-transitory computer-readable medium containing instructions executable by at least one processor of a device, the non-transitory computer-readable medium comprising one or more instructions for:
- receiving, in a home network and from a second network device, a first discovery message, the first discovery message including a visited network identifier for a roaming session;
- matching the visited network identifier to a network identifier in a Session Management Function (SMF) profile;
- and
- sending, to the second network device, a first identifier for a home SMF (H-SMF) for the roaming session based on the visited network identifier.
