Abstract

The present invention relates to a method and apparatus for registering an access point through a WiFi network using information obtained from a common device in a cellular-WiFi convergence system. The present invention provides a method in which a sub-RAT system entity obtains main RAT system information through a common device and a WiFi network thereof in a communication system in which a cellular system and a WiFi system are converged, and notifies a managing device of information thereon through the WiFi network.

First claim

What is claimed is:

1. A method for obtaining information related to a cellular system in a wireless communication system, the method performed by an Access Point (AP) and comprising:
transmitting a request message to a multi-radio access technology (RAT) device through a Wireless Local Area Network (WLAN) system network for requesting information related to the cellular system;
receiving a response message from the multi-RAT device through the cellular system in response to the request message, the response message including the information related to the cellular system; and
transmitting a report message including the information related to the cellular system to a managing server through the WLAN system network,
wherein the request message is an advanced main RAT system information request (ARSI-REQ) message including a parameter representing an action code,
wherein the action code is expressed in bitmap form and requests at least one of a plurality of actions,
wherein the action code is used to perform at least accepting the request message only when a cellular device belonging to the cellular system is in an active mode, accepting the request message irrespective of a state of the cellular device, requesting identification information of a network of the cellular system, requesting identification information of a base station (BS) controller of the cellular system, requesting identification information of a cell or a BS of the cellular system, or requesting position information of the cellular device, and
wherein the request message is transmitted using an IEEE 802.11 MAC frame format.

2. The method of claim 1 , wherein the response message is an ARSI-RSP message.

3. The method of claim 1 , wherein the report message further includes information related to the WLAN system in addition to the information related to the cellular system.
