Abstract

A system is provided which is capable of connecting a call without degrading the security level in a mobile terminal network, even when a call addressed to a user equipment (UE) arrives via the Internet or a home network. A femto base station receives a packet addressed to a UE via the Internet or a home network, and starts a paging procedure. The UE establishes an RRC connection to the femto base station. The UE transmits, to the femto base station, a paging response addressed to the SGSN. The femto base station performs NAS verification. If the femto base station detects the paging response to a paging request that the femto base station itself has issued, the femto base station changes the service type of the service request received from the UE from the paging response to signaling.

Claims4

Dependent claims

An integrated circuit configured to control operation of a user equipment (UE), the integrated circuit comprising:

reception circuitry, which, in operation, receives a paging message from a traffic offloading apparatus for the UE when the UE is in idle mode, the paging message regarding downlink offload traffic arriving at the traffic offloading apparatus;
control circuitry, which is coupled to the reception circuitry and which, in operation, controls transmission of a service request message as a paging response to the traffic offloading apparatus, a service type in the service request message indicating the paging response which triggers the traffic offloading apparatus to modify the service type in the service request message to indicate a UE-initiated service request and to send the modified service request message to a first Serving General Packet Service Support Node (SGSN).

Dependencies are inferred from the claim text.
