Abstract

Claims (50)

1 . A wireless transmit/receive unit (WTRU), comprising a transceiver and one or more processors, configured to:

provision the WTRU with identifying information;

receive, from a network, a first broadcast message comprising a first indication that the network can provision devices with one or more network credentials;

send, to the network and based on the first broadcast message, a registration request that comprises the identifying information previously provisioned to the WTRU and a second indication the WTRU is registering in response to the first indication to obtain the network credentials;

receive a second broadcast message from the network, wherein the second broadcast message includes a network identifier indicating that the network can provision the WTRU with the one or more network credentials, and

perform a registration procedure with the network, wherein the registration procedure with the network is performed based on the first broadcast message and the second broadcast message;

receive the one or more network credentials;

perform a de-registration procedure with the network; and

perform, using the one or more network credentials, a second registration procedure.

2 . The WTRU of claim 1 , further configured to:

determine, based on the first broadcast message, to request the second broadcast message, and

send a system information request to the network for the second broadcast message.

3 . The WTRU of claim 1 , wherein the one or more network credentials include at least one of:

a network identifier,

a subscription identifier,

a security parameters or security certificates, or location information.

4 . The WTRU of claim 1 , wherein being configured to send the registration request comprises being configured to send the registration request based on an event comprising at least one of:

the WTRU powering on,

the WTRU being powered on and off in a sequence,

receiving an indication from a user interface such as a button or a graphical user interface (GUI),

the WTRU discovering no network for which it already has provisioned the one or more network credentials, or

a change to a location of the WTRU.

5 . The WTRU of claim 1 , wherein the one or more network credentials are received in a non-access stratum (NAS) message.

6 . The WTRU of claim 1 , wherein the one or more network credentials are received in a user plane procedure with a server.

7 . The WTRU of claim 4 , wherein the registration procedure further comprises:

receiving a single-network slice selection assistance information (S-NSSAI) from the network, and

using the S-NSSAI to connect to the server.

8 . The WTRU of claim 1 , wherein the WTRU comprises a user equipment (UE).

9 . A method implemented in a wireless transmit/receive unit (WTRU), the method comprising:

causing provisioning of the WTRU with identifying information;

receiving, from a network, a first broadcast message comprising a first indication that the network can provision devices with one or more network credentials;

sending, to the network and based on the first broadcast message, a registration request that comprises the identifying information previously provisioned in the WTRU and a second indication the WTRU is registering in response to the first indication to obtain the one or more network credentials;

receiving, a second broadcast message from the network, wherein the second broadcast message includes a network identifier indicating that the network can provision the WTRU with the one or more network credentials, and

performing a registration procedure with the network, wherein performing the registration procedure with the network is based on the first broadcast massage and the second broadcast message;

receiving the one or more network credentials;

performing a de-registration procedure with the network; and

performing, using the one or more network credentials, a second registration procedure.

10 . The method of claim 9 , comprising:

determining, based on the first broadcast message, to request the second broadcast message, and

sending a system information request to the network for the second broadcast message.

11 . The method of claim 9 , wherein the one or more network credentials include at least one of:

a network identifier,

a subscription identifier,

a security parameters or security certificates, or location information.

12 . The method of claim 9 , wherein sending the registration request is based on an event that causes the apparatus to initiate the operations, and wherein the event comprises at least one of:

the WTRU powering on,

the WTRU being powered on and off in a sequence,

receiving an indication from a user interface such as a button or a graphical user interface (GUI),

the WTRU discovering no network for which it already has provisioned the network credentials, or

a change to a location of the WTRU.
