## Abstract

A mobility management node receives, from a wireless device, a first message requesting registration of a store and forward (SF) mode, and sends, to an authentication management node, an authentication request message indicating the SF mode. The mobility management node receives, from the authentication management node, an authentication response message, and sends, to the wireless device, a second message requesting authentication.

## Claims

### Claim 1

A method comprising:
receiving, by a mobility management node from a wireless device, a first message requesting registration of a store and forward (SF) mode;
sending, by the mobility management node to an authentication management node, an authentication request message indicating the SF mode;
receiving, by the mobility management node from the authentication management node, an authentication response message; and
sending, by the mobility management node to the wireless device, a second message requesting authentication.

### Claim 2 (depends on 1)

The method of claim 1, wherein, in the SF mode, a connection to a ground network from a satellite is not available when the wireless device interacts with the satellite.

### Claim 3 (depends on 1)

The method of claim 1, wherein the authentication response message comprises an authentication token.

### Claim 4 (depends on 1)

The method of claim 1, further comprising sending, by the mobility management node to the wireless device, a registration request.

### Claim 5 (depends on 4)

The method of claim 4, wherein the registration request comprises an authentication token.

### Claim 6 (depends on 1)

The method of claim 1, wherein the mobility management node comprises an access and mobility management function (AMF).

### Claim 7 (depends on 1)

The method of claim 1, wherein the authentication management node comprises an authentication server function (AUSF).

### Claim 8

A mobility management node comprising one or more processors and memory storing instructions that, when executed by the one or more processors, cause the mobility management node to:
receive, from a wireless device, a first message requesting registration of a store and forward (SF) mode;
send, to an authentication management node, an authentication request message indicating the SF mode;
receive, from the authentication management node, an authentication response message; and
send, to the wireless device, a second message requesting authentication.

### Claim 9 (depends on 8)

The mobility management node of claim 8, wherein, in the SF mode, a connection to a ground network from a satellite is not available when the wireless device interacts with the satellite.

### Claim 10 (depends on 8)

The mobility management node of claim 8, wherein the authentication response message comprises an authentication token.

### Claim 11 (depends on 8)

The mobility management node of claim 8, further comprising sending, by the mobility management node to the wireless device, a registration request.

### Claim 12 (depends on 11)

The mobility management node of claim 11, wherein the registration request comprises an authentication token.

### Claim 13 (depends on 8)

The mobility management node of claim 8, wherein the mobility management node comprises an access and mobility management function (AMF).

### Claim 14 (depends on 8)

The mobility management node of claim 8, wherein the authentication management node comprises an authentication server function (AUSF).

### Claim 15

A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors of a wireless device, cause the wireless device to:
receive, from a wireless device, a first message requesting registration of a store and forward (SF) mode;
send, to an authentication management node, an authentication request message indicating the SF mode;
receive, from the authentication management node, an authentication response message; and
send, to the wireless device, a second message requesting authentication.

### Claim 16 (depends on 15)

The non-transitory computer-readable medium of claim 15, wherein, in the SF mode, a connection to a ground network from a satellite is not available when the wireless device interacts with the satellite.

### Claim 17 (depends on 15)

The non-transitory computer-readable medium of claim 15, wherein the authentication response message comprises an authentication token.

### Claim 18 (depends on 15)

The non-transitory computer-readable medium of claim 15, further comprising sending, by the mobility management node to the wireless device, a registration request.

### Claim 19 (depends on 18)

The non-transitory computer-readable medium of claim 18, wherein the registration request comprises an authentication token.

### Claim 20 (depends on 15)

The non-transitory computer-readable medium of claim 15, wherein the mobility management node comprises an access and mobility management function (AMF).
