Wireless communication system, base station device, move control node, and method of wireless communication
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.
1. A method comprising:
receiving an attach request message from a wireless communication apparatus;
transmitting, to the mobility management entity, the attach request message contained in an initial UE message, the initial UE message including both first information indicating a tracking area to which a cell of the base station belongs and second information indicating whether or not a type of the cell of the base station is a macro cell;
receiving an attach accept message, from the mobility management entity, including third information of at least one tracking area to which the wireless communication apparatus is registered; and
transmitting the attach accept message to the wireless communication apparatus.
2. The method according to claim 1 ,
wherein the type of the cell of the base station is a type representative of a size of the cell.
3. The method according to claim 1 ,
wherein the second information indicates that the type of the cell of the base station is a macro cell or a femto cell.
4. A base station comprising at least one processor configured to operate as:
a receiver configured to receive an attach request message from a wireless communication apparatus; and
a transmitter configured to transmit, to the mobility management entity, the attach request message contained in an initial UE message, the initial UE message including both first information indicating a tracking area to which a cell of the base station belongs and second information indicating whether or not a type of the cell of the base station is a macro cell,
wherein the receiver receives an attach accept message, from the mobility management entity, including third information of at least one tracking area to which the wireless communication apparatus is registered, and
wherein the transmitter transmits the attach accept message to the wireless communication apparatus.
5. The base station according to claim 4 ,
wherein the type of the cell of the base station is a type representative of a size of the cell.
6. The method according to claim 4 ,
wherein the second information indicates that the type of the cell of the base station is a macro cell or a femto cell.
7. The base station according to claim 4 , comprising a controller that determines a mobility management entity to which to transmit the attach request message.
8. A method comprising:
receiving, from a base station, an attach request message contained in an initial UE message, the initial UE message including both first information indicating a tracking area to which a cell of the base station belongs and second information indicating whether or not a type of the cell of the base station is a macro cell; and
transmitting an attach accept message, to the base station, including third information of at least one tracking area to which the wireless communication apparatus is registered.
9. The method according to claim 8 ,
wherein the type of the cell of the base station is a type representative of a size of the cell.
10. The method according to claim 8 ,
wherein the second information indicates that the type of the cell of the base station is a macro cell or a femto cell.
