Network slice selection assistance information configuration
Apparatuses, methods, and systems are disclosed for NSSAI configuration. One method includes determining, within a unified data management function, a default network slice selection assistance information for a public land mobile network for a remote unit. The method includes providing the default network slice selection assistance information to the remote unit.
1. A method comprising:
generating, within a unified data management function, a default network slice selection assistance information for a public land mobile network for a remote unit; and
providing the default network slice selection assistance information to the remote unit via an access and mobility management function.
2. The method of claim 1 , wherein the default network slice selection assistance information is included in a non-access stratum signaling message sent from an access and mobility management function.
3. The method of claim 1 , wherein, in response to providing the default network slice selection assistance information, stored default network slice selection assistance information is updated by the remote unit.
4. The method of claim 1 , wherein determining the default network slice selection assistance information for a public land mobile network for the remote unit comprises determining the default network slice selection assistance information for public land mobile networks for which no specific configured network slice selection assistance information has been provided to the remote unit.
5. An apparatus comprising:
a processor that generates, within a unified data management function, a default network slice selection assistance information for a public land mobile network for a remote unit; and
a transmitter that provides the default network slice selection assistance information to the remote unit via an access and mobility management function.
6. The apparatus of claim 5 , further comprising a receiver that receives an acknowledgment indicating that the remote unit is updated with the default network slice selection assistance information.
7. The apparatus of claim 5 , further comprising a receiver that receives information indicating a subscription change.
8. The apparatus of claim 7 , wherein the processor updates the default network slice selection assistance information in response to receiving the information indicating the subscription change.
9. A method comprising:
receiving, at a remote unit, a default network slice selection assistance information for a public land mobile network, wherein a unified data management function generates the default network slice selection assistance information and provides the default network slice selection assistance information to the remote unit via an access and mobility management function.
10. The method of claim 9 , wherein the default network slice selection assistance information is included in a non-access stratum signaling message sent from an access and mobility management function.
11. The method of claim 9 , further comprising, in response to receiving the default network slice selection assistance information, updating stored default network slice selection assistance information of the remote unit.
12. The method of claim 9 , wherein the unified data management function determines the default network slice selection assistance information by determining the default network slice selection assistance information for public land mobile networks for which no specific configured network slice selection assistance information has been provided to the remote unit.
13. An apparatus comprising:
a receiver that receives a default network slice selection assistance information for a public land mobile network, wherein a unified data management function generates the default network slice selection assistance information and provides the default network slice selection assistance information to the apparatus via an access and mobility management function.
14. The apparatus of claim 13 , further comprising a transmitter that transmits an acknowledgment indicating that the apparatus is updated with the default network slice selection assistance information.
15. The apparatus of claim 13 , wherein the default network slice selection assistance information is included in a non-access stratum signaling message sent from an access and mobility management function.
16. The apparatus of claim 13 , wherein the unified data management function determines the default network slice selection assistance information by determining the default network slice selection assistance information for public land mobile networks for which no specific configured network slice selection assistance information has been provided to the apparatus.
