Abstract:
1. A method of controlling a service in a server in charge of a control plane in a mobile communication network, the method comprising: receiving, by the server, an initial message including both an identifier of a local gateway and an selected IP traffic offload (SIPTO) service-related indicator from a Home (e)NodeB, the initial message being an S1 application protocol (S1-AP) based message and including a request message from a user equipment (UE) in an idle mode, the request message of the UE in the idle mode corresponding to at least one of a tracking area update (TAU) request message, a radio area update (RAU) request message, and an attach request message, and each of the TAU request message, the RAU request message, the attach message from the UE in idle mode including information indicating whether the UE approves a provision of the SIPTO service or not; upon receiving the initial message, determining whether to provide the SIPTO service to the UE in consideration of all of the information indicating whether the UE approves the provision of the SIPTO service or not, the identifier of the local gateway, and the SIPTO service-related indicator; when it is determined to provide the SIPTO service to the UE, determining whether to block a local IP access (LIPA) service to the UE; when it is determined to provide the SIPTO service and to block the LIPA service to the UE, and when there exists a bearer previously generated for the LIPA service, transmitting, to the UE, a bearer deactivation request message to substitute the bearer previously generated for the LIPA service with a bearer for the SIPTO service; when it is determined to provide the SIPTO service and to block the LIPA service to the UE, transmitting LIPA service permission information and LIPA filter information to the local gateway; and when it is determined to provide the SIPTO service and to block the LIPA service to the UE transmitting all of the LIPA service permission information, the filter information, and a notification for the LIPA service to the Home (e)NodeB, wherein the LIPA service permission information is used to inform the Home (e)NodeB and the local gateway that the LIPA service is not permitted, wherein the filter information is used by the Home (e)NodeB and the local gateway to block data from the LIPA service generated by the UE, and to bypass data from only the SIPTO service generated by the UE, and wherein the notification for the LIPA service is used to inform the UE that the LIPA service is not permitted.
