<p>Disclosed is a method to support SIPTO. The method to support SIPTO comprises the following steps of: transmitting, by a base station to be targeted, to an MME and an ID of a local home network to which the base station to be targeted belongs when the base station to be targeted is located in the local home network; and determining, by the MME, whether UE has moved out of a local home network to which a source base station belongs based on an ID of the local home network of the source base station and the ID of the local home network of the base station to be targeted. By applying the present invention, it can accurately be determined whether the UE has moved out of a local home network to which a source base station belongs, thereby correctly triggering a bearer disconnection process. As a result, resources can timely be released or an SGW can accurately be selected.</p> |
