METHODS OF HOTSPOT DETECTION AND HANDOVER DECISION FOR 3G AND WLAN INTERWORKING

摘要

The present invention provides a method for a user terminal to detect a service area of a wireless local area network in a mobile communication system interworking a wide area network and a wireless local area network, and a method for selecting a communication network that is easier to service among the communication networks when performing a handover. Is to suggest.;In the present invention, the user terminal receives a pilot channel and a broadcast channel transmitted from a base station of a wide area mobile communication network and an access point of a wireless local area network, so that the user terminal without increasing the complexity of the hardware structure, It facilitates the detection of the service area and the determination of the communication network to perform the handover.;Wireless Local Area Networks (WLANs), Hotspots, Horizontal Handovers, Vertical Handovers, Access Points, Pilot Channels, Broadcast Channels
