Abstract

Provided is compact base station device that reduces the processing load with an upper layer network device by reducing the amount of signaling with an upper layer network device. In the device, a CSG member management device (102) stores CSG member information beforehand. A network message generation unit (107) generates a message used for collectively registering the CSG member terminals stored in the CSG member management unit (102), in an upper layer network device. At startup, a network interface unit (108) transmits a message generated by the network message generation unit (107) to the upper layer network device. In response to the message transmitted by the network interface unit (108), a network message analysis unit (106) acquires from the upper layer network device parameter information for connecting to the CSG member terminals.

Claims

1. A small Cell comprising:

a management section configured to pre-store information regarding grouped terminals;

a generation section configured to crate a message for collectively registering the grouped terminals with an upper layer network apparatus;

a network transmission section configured to transmit the message generated by the generation section to the upper layer network apparatus at a predetermined time; and

an acquisition section configured to acquire from the upper layer network apparatus, as a response to the message transmitted by the network transmission section, a parameter for connecting with the grouped terminals.

2. The small cell according to claim 1, wherein, for the predetermined time, the network transmission section is configured to transmit the message upon activation.

3. The small cell according to claim 1, wherein:

the management section is configured to update the stored information regarding the grouped terminals as appropriate; and

for the predetermined time, the network transmission section is configured to transmit the message when the information regarding the grouped terminals is updated at the management section.

4. The small cell according to claim 1, wherein:

the management section is configured to update the stored information regarding the grouped terminals as appropriate; and

the generation section is configured to generate the message to register with the upper layer network apparatus a terminal for which the management section performed updating.

5. The small cell according to claim 1, further comprising:

a radio reception section configured to receive a connection request from one of the grouped terminals; and

a radio transmission section configured to transmit, upon receiving, the connection request through the radio reception section and to the terminal that tirade the connection request, a message including the parameter acquired through the acquisition section, wherein

the acquisition section is configured to acquire the parameter from the upper layer network apparatus prior to receiving the connection request through the radio reception section.

6. A signaling method for a small cell, comprising:

a step of pre-storing information regarding grouped terminals;

a step of generating a message for collectively registering the grouped terminals with an upper layer network apparatus; and

a step of transmitting the generated message to the upper layer network apparatus at a predetermined time.
