Abstract

Claims (32)

1 . A network entity apparatus, comprising:

a transceiver; and

a processor coupled to the transceiver, the processor configured to cause the apparatus to:

detect that a new version of network software is available;

determine an incorporation plan for migrating to the new version of the network software;

request a new network slice instance for deploying the new version of the network software according to the determined incorporation plan, wherein one or more user equipment (“UE”) devices are assigned to the new network slice instance; and

monitor performance of the one or more UE devices using the new version of the network software in the new network slice instance.

2 . The apparatus of claim 1 , wherein the new network slice instance is assigned to a new single network slice selection assistance information (“S-NSSAI”) such that the new network slice instance is visible to the one or more UE devices, the subscription data of the one or more UE devices updated for the new network slice instance.

3 . The apparatus of claim 1 , wherein the new network slice instance is associated with an existing single network slice selection assistance information (“S-NSSAI”) such that the new network slice is not visible to the one or more UE devices, the one or more UE devices assigned to the new network slice during a registration procedure.

4 . The apparatus of claim 1 , wherein the processor is configured to cause the apparatus to receive a notification in response to the new version of the network software being available for deployment.

5 . The apparatus of claim 1 , wherein the processor is configured to cause the apparatus to deploy the new version of the network software on a current network that the one or more UE devices are connected to according to the incorporation plan.

6 . The apparatus of claim 1 , wherein the incorporation plan comprises an identifier for the new network slice instance and one or more steps for implementing the incorporation plan, the one or more steps each comprising a replacement condition and a cancel condition.

7 . The apparatus of claim 6 , wherein a step of the one or more steps defines a group of UE devices of the one or more UE devices to migrate to the new network slice instance to use the new version of the network software.

8 . The apparatus of claim 7 , wherein the processor is configured to cause the apparatus to proceed to a next step of the incorporation plan in response to the monitored performance of the one or UE devices satisfying the replacement condition for a step of the incorporation plan.

9 . The apparatus of claim 8 , wherein the processor is configured to cause the apparatus to remove a current network slice instance that the one or more UE devices were previously connected to in response to each of the one or more UE devices being migrated to the new network slice instance.

10 . The apparatus of claim 7 , wherein the processor is configured to cause the apparatus to cancel deployment of the new software version in the new network slice instance in response to the monitored performance of the one or more UE devices not satisfying the replacement condition for a step of the incorporation plan.

11 . The apparatus of claim 10 , wherein cancelling deployment comprises modifying a number of UE devices that the new network slice instance can support until the monitored performance satisfies the replacement condition for the step of the incorporation plan.

12 . The apparatus of claim 11 , wherein the processor is configured to cause the apparatus to remove the new network slice instance in response to removing each UE device that is migrated to the new network slice instance back to a previous network slice instance.

13 . The apparatus of claim 1 , wherein the processor is configured to cause the apparatus to transmit a notification indicating one of success and failure of deployment of the new version of the network software in the new network slice instance.

14 . A method of a network entity apparatus, comprising:

detecting that a new version of network software is available;

determining an incorporation plan for migrating to the new version of the network software;

requesting a new network slice instance for deploying the new version of the network software according to the determined incorporation plan, wherein one or more user equipment (“UE”) devices are assigned to the new network slice instance; and

monitoring performance of the one or more UE devices using the new version of the network software in the new network slice instance.

15 . A network entity apparatus, comprising:

a transceiver; and

a processor coupled to the transceiver, the processor configured to cause the apparatus to:

receive a request to create a new network slice instance according to an incorporation plan for deployment of a new version of network software and migrating one or more user equipment (“UE”) devices to the new network slice instance;

create the new network slice instance according to the incorporation plan; and

one of:

assign the new network slice instance to a new single network slice selection assistance information (“S-NSSAI”); and

assign the new network slice instance to an existing S-NSSAI.
