Abstract: A method for selecting an access network in a terminal of a mobile communication system according to one embodiment of the present specification comprises the steps of: if traffic is generated in the terminal, selecting an access network according to the characteristics of the generated traffic and network selection policy information; and transmitting and receiving the generated traffic via the selected access network. According to the embodiment, the present invention adjusts priorities of accesses given to users and applications in a wireless communication system including heterogenerous networks, thereby reducing processes for reselecting an access network of a user terminal, and reducing the cases of unnecessarily accessing a network having a low priority or requiring high costs for a long time. Therefore, the present invention can enhance user convenience and improve communication efficiency.

Abstract: A method of supporting handover of a terminal by a mobility management entity (MME) of a mobile communication system is provided. The method includes receiving, from a base station, a first message for handover to another network. The first message includes information on a cell to which the terminal is handed over. The method also includes transmitting, to a server, a second message for reporting information related to a location of the terminal and for providing a location continuity based on the first message. A terminal having both a 3GPP communication function and a WiFi function automatically switches on and off a WLAN according to a location, setting, or a pattern of a user, thereby preventing unnecessary battery consumption or performance deterioration and searching for an available WLAN in advance to access the WLAN.
