Server for control plane at mobile communication network and method for controlling local IP access service
First Claim
1. A method of controlling a Local IP Access (LIPA) service in a core network entity taking charge of the control plane within a mobile communication network, the method comprising:
- receiving an initial message from Home (e)NodeB, wherein the initial message comprises at least one of LIPA related information and capability information, and the LIPA related information comprises at least one of Access Point Name (APN) for LIPA and information for a local gateway, and the capability information comprises a first indicator indicating whether the Home (e)NodeB supports a LIPA function, and the initial message comprises an attachment request message by a terminal;
determining whether the terminal uses a LIPA service at the Home (e)NodeB by considering at least one of the LIPA related information within the initial message, the capability information within the initial message, and subscriber information of the terminal, upon receiving the initial message;
storing a result of the determination;
generating an attachment accept message comprising a second indicator indicating whether the terminal uses a LIPA service at the Home (e)NodeB;
transmitting an initial setup message comprising the generated attachment accept message to the Home (e)NodeB for transmission to the terminal; and
receiving, from the terminal via the Home (e)NodeB, a request related to bearer setup for LIPA only when the second indicator indicates that the terminal uses the LIPA service at the Home (e)NodeB.

Abstract
Disclosed is a method of controlling a LIPA (Local IP Access) service in a server taking charge of the control plane within a mobile communication network. The method of controlling a LIPA service may include receiving an initial message from Home (e)NodeB. The initial message may include at least one of LIPA related information and capability information. The LIPA related information may include at least one of APN (Access Point Name) for LIPA and information for a local gateway, and the capability information may include an indicator indicating whether the Home (e)NodeB supports a LIPA function, and the initial message may include an access request message by a terminal. The method of controlling a LIPA service may further include determining whether the terminal can use a LIPA service at the Home (e)NodeB by considering at least one of the LIPA related information within the initial message, the capability information within the initial message, and subscriber information of the terminal, upon receiving the initial message; storing a result of the determination; generating an access accept message including an indicator indicating whether the terminal can use a LIPA service at the Home (e)NodeB; and transmitting an initial setup message including the generated access accept message to the Home (e)NodeB.

11. A core network entity of taking charge of a Local IP Access (LIPA) service within a mobile communication network, the core network entity comprising:
-
a receiver configured to receive an initial message comprising LIPA related information and capability information from Home (e)NodeB, wherein the LIPA related information comprises at least one of Access Point Name (APN) for LIPA and information for a local gateway, and the capability information comprises a first indicator indicating whether the Home (e)NodeB supports a LIPA function, and the initial message comprises an attachment request message by a terminal; a controller configured to control to determine whether the terminal uses a LIPA service at the Home (e)NodeB by considering at least one of the LIPA related information within the initial message, the capability information within the initial message, and subscriber information of the terminal, in response to the initial message, and store a result of the determination; and a transmitter configured to encapsulate an attachment accept message comprising a second indicator indicating whether the terminal uses a LIPA service at the Home (e)NodeB in an initial setup message to transmit to the Home (e)NodeB for transmission to the terminal, wherein the receiver is further configured to receive, from the terminal via the Home (e)NodeB, a request related to bearer setup for LIPA only when the second indicator indicates that the terminal uses the LIPA server at the Home (e)NodeB. - View Dependent Claims (12, 13, 14, 15, 16)
