BASE STATION DEVICE, GATEWAY DEVICE, CALL CONNECTING METHOD, AND WIRELESS COMMUNICATION SYSTEM

摘要

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.

1. A traffic offload system comprising:
a user equipment (UE), and a traffic offloading apparatus including:
a pager configured to page the UE in idle mode for downlink offload traffic arriving at the traffic offloading apparatus;a receiver configured to receive a service request message from the paged UE as a paging response, a service type in the received service request message indicating the paging response;a controller configured to modify the service type in the service request message to indicate a UE-initiated service request; anda transmitter configured to send the modified service request message to a Serving General Packet Radio Service (GPRS) Support Node (SGSN).
