Abstract

The present invention provides a method for controlling access of a terminal if the terminal accesses from a wireless LAN network to a mobile communication network, when the mobile communication network (for example, UMTS, LTE and the like) and the wireless LAN network are linked in a wireless communication system. Furthermore, the present invention provides a method for transmitting information on connectable peripheral wireless LAN networks. Thus, the present invention can reduce a load of a network since the network can control the access of a terminal, and can reduce unnecessary power consumption and solve a connection delay problem by providing a valid wireless LAN network list to the terminal.

Claims

1. A method for connecting to a wireless local area network (LAN) access point by a terminal in a wireless communication system, the method comprising:

receiving information on a connectable access point (AP) list from a base station;

searching neighboring APs according to the received connectable AP list and transmitting, to the base station, a connection failure list of APs which the terminal has failed to connect to among the searched APs;

receiving, from the base station, a connection-related AP list updated based on the connection failure AP list; and

attempting to connect to a wireless LAN according to the received connection-related AP list.
