SERVICE CONTROL APPARATUS, RELAY APPARATUS, FEMTOCELL BASE STATION, COMMUNICATION SYSTEM, CONTROL METHOD, AND PROGRAM
First Claim
1. A service control apparatus that provides a PS (Packet Switching) service to UE (User Equipment) that are present in a communication area that is created by a femtocell base station in an IMS (IP Multimedia subsystem) network, comprising:
- tunnel-establishing means that establishes IPsec (Security Architecture for Internet Protocol) tunnels with said femtocell base station; and
service control means that, when there are requests for provision of said PS service from a plurality of said UE, provides said PS service to said plurality of UE by way of a common IPsec tunnel that was established by said tunnel-establishing means.

Abstract
A service control apparatus provides a PS (Packet Switching) service to UE (User Equipment) that are present in a communication area created by a femtocell base station in an IMS (IP Multimedia Subsystem) network. The service control apparatus includes tunnel establishing means that establishes an IPsec (Security Architecture for Internet Protocol) tunnel with the femtocell base station; and service control means that, when there are requests for provision of the PS service from a plurality of the UE, provides the PS service to the plurality of UE by way of a common IPsec tunnel that was established by the tunnel establishing means.
