## Abstract

A method and apparatus are disclosed. In an example from the perspective of a User Equipment (UE), the UE provides information related to multiple Universal Subscriber Identity Modules (USIM) of the UE to a first network.

## Claims

### Claim 1

A method of a User Equipment (UE) supporting multiple Universal Subscriber Identity Modules (USIM), the method comprising:
when a first USIM and a second USIM are concurrently active in the UE, indicating, to a first network, that the UE prefers or requests a multi-USIM solution from the first network; and
responsive to a number of active USIMs in the UE changing upon the second USIM in the UE being removed from the UE and the first USIM being the only USIM active in the UE, indicating, to the first network in a registration procedure to the first network, that the UE does not prefer or request the multi-USIM solution after indicating to the first network that the UE prefers or requests the multi-USIM solution.

### Claim 2 (depends on 1)

The method of claim 1, wherein:
the UE indicates, to the first network in a second registration procedure to the first network, that the UE prefers or requests the multi-USIM solution from the first network.

### Claim 3 (depends on 1)

The method of claim 1, wherein:
the first network is Access and Mobility Management Function (AMF).

### Claim 4 (depends on 1)

The method of claim 1, wherein:
the multi-USIM solution is to solve a problem due to the multiple USIMs.

### Claim 5 (depends on 4)

The method of claim 4, wherein:
the problem includes a service interruption for the first USIM while the UE is communicating via the second USIM.

### Claim 6 (depends on 1)

The method of claim 1, wherein:
the multi-USIM solution includes a mechanism allowing for release of an ongoing connection associated with the first USIM.

### Claim 7

A communication device supporting multiple Universal Subscriber Identity Modules (USIM), comprising:
a processor; and
memory comprising processor-executable instructions that when executed by the processor cause performance of operations, the operations comprising:
when a first USIM and a second USIM are concurrently active in the communication device, indicating, to a first network, that the communication device prefers or requests a multi-USIM solution from the first network; and
responsive to a number of active USIMs in the communication device changing upon the second USIM in the communication device being removed from the communication device and the first USIM being the only USIM active in the communication device, indicating, to the first network in a registration procedure to the first network, that the communication device does not prefer or request the multi-USIM solution after indicating to the first network that the communication device prefers or requests the multi-USIM solution.

### Claim 8 (depends on 7)

The communication device of claim 7, wherein:
the communication device indicates, to the first network in a second registration procedure to the first network, that the communication device prefers or requests the multi-USIM solution from the first network.

### Claim 9 (depends on 7)

The communication device of claim 7, wherein:
the first network is Access and Mobility Management Function (AMF).

### Claim 10 (depends on 7)

The communication device of claim 7, wherein:
the multi-USIM solution is to solve a problem due to the multiple USIMs.

### Claim 11 (depends on 10)

The communication device of claim 10, wherein:
the problem includes a service interruption for the first USIM of the communication device while the communication device is communicating via the second USIM of the communication device.

### Claim 12 (depends on 7)

The communication device of claim 7, wherein:
the multi-USIM solution includes a mechanism allowing for release of an ongoing connection associated with the first USIM.

### Claim 13

A non-transitory computer-readable medium comprising processor-executable instructions that when executed cause performance of operations, comprising:
when a first Universal Subscriber Identity Module (USIM) and a second USIM are concurrently active in a device, indicating, to a first network, that the device prefers or requests a multi-USIM solution from the first network; and
responsive to a number of active USIMs in the device changing upon the second USIM in the device being removed from the device and the first USIM being the only USIM active in the device, indicating, to the first network in a registration procedure to the first network, that the device does not prefer or request the multi-USIM solution after indicating to the first network that the device prefers or requests the multi-USIM solution.

### Claim 14

A method of a User Equipment (UE) supporting multiple Universal Subscriber Identity Modules (USIM), the method comprising:
when a first USIM and a second USIM are concurrently active in the UE, indicating, to a first network in a registration procedure to the first network, that the UE prefers or requests a multi-USIM solution from the first network, wherein the multi-USIM solution includes a mechanism allowing for release of an ongoing connection associated with the first USIM; and
responsive to a number of active USIMs in the UE changing upon the second USIM in the UE changing from being active to being not active and the first USIM being the only USIM active in the UE, indicating, to the first network in a second registration procedure to the first network, that the UE does not prefer or request the multi-USIM solution after indicating to the first network that the UE prefers or requests the multi-USIM solution.

### Claim 15 (depends on 14)

The method of claim 14, wherein:
the second USIM is not active when the second USIM is removed from the UE.

### Claim 16 (depends on 14)

The method of claim 14, wherein:
the first network is Access and Mobility Management Function (AMF).
