## Abstract

A base station is provided. The base station includes a transmitter and a receiver. The transmitter transmits, to a node including mobility management function, a setup message, the message including both first information about a tracking area supported in the base station and second information indicating a type of the cell of the base station. The receiver receives a response message of the setup message from the node including mobility management function.

## Claims

### Claim at position 1

1-9. (canceled)

### Claim 10

A base station comprising:
a receiver configured to receive an attach request message from a wireless communication apparatus; and
a transmitter configured to send, to a mobility management entity, a first message including both first information indicating a location of the base station and second information indicating whether or not a type of the cell of the base station is a macro cell, if the base station receives the attach request message.

### Claim 11 (depends on 10)

The base station according to claim 10, wherein the type of the cell of the base station is a type representative of a size of the cell.

### Claim 12 (depends on 10)

The base station according to claim 10, wherein the second information indicates that the type of the cell of the base station is a macro cell or a femto cell.

### Claim 13 (depends on 10)

The base station according to claim 10, wherein the first message is a UE initial message.

### Claim 14 (depends on 10)

The base station according to claim 10, wherein
the receiver receives a second message, from the mobility management entity, including third information of a tracking area to which the wireless communication apparatus is registered, and
the transmitter transmits the second message to the wireless communication apparatus.

### Claim 15 (depends on 14)

The base station according to claim 14, wherein the second message is an attach accept message.

### Claim 16

A method by a base station comprising:
receiving an attach request message from a wireless communication apparatus; and
sending, to a mobility management entity, a first message including both first information indicating a location of the base station and second information indicating whether or not a type of the cell of the base station is a macro cell, if the base station receives the attach request message.

### Claim 17 (depends on 16)

The method according to claim 16, wherein the type of the cell of the base station is a type representative of a size of the cell.

### Claim 18 (depends on 16)

The method according to claim 16, wherein the second information indicates that the type of the cell of the base station is a macro cell or a femto cell.

### Claim 19 (depends on 16)

The method according to claim 16, wherein the first message is a UE initial message.

### Claim 20 (depends on 16)

The method according to claim 16, further comprising:
receiving a second message, from the mobility management entity, including third information of a tracking area to which the wireless communication apparatus is registered; and
transmitting the second message to the wireless communication apparatus.

### Claim 21 (depends on 20)

The method according to claim 20, wherein the second message is an attach accept message.
