## Abstract

A home base station registration request message includes data identifying whether or not the home base station comprises an open access mode or a closed access mode home base station.

## Claims

### Claim 1

A base station which communicates with a base station gateway, the base station comprising:
a transmission circuit configured to transmit a base station register request to the base station gateway,
wherein the base station register request includes at least information identifying whether the base station is an open mode base station or a closed mode base station, wherein the information identifying whether the base station is an open mode base station or a closed mode base station is based on data stored in a memory; and
a receiving circuit configured to receive a base station register accept message from the base station gateway.

### Claim 2

A method comprising:
transmitting, from a base station to a base station gateway, a base station register request,
wherein the base station register request includes at least information identifying whether the base station is an open mode base station or a closed mode base station, wherein the information identifying whether the base station is an open mode base station or a closed mode base station is based on data stored in a memory; and
receiving, by the base station, from the base station gateway, a base station register accept message.

### Claim 3 (depends on 1)

The base station according to claim 1, wherein the data stored in the memory comprises the information identifying whether the base station is an open mode base station or a closed mode base station.

### Claim 4 (depends on 2)

The base station according to claim 2, wherein the data stored in the memory comprises the information identifying whether the base station is an open mode base station or a closed mode base station.
