In addition, the second operator identification information may be transmitted in a reserved field of an information element (IE) included in the beacon signal or the probe response signal.

According to another embodiment of the present invention, there is provided a method for accessing a wireless network based on operator identification information, wherein the access method comprises: (a) a mobile terminal connected to a broadband wireless network from a second operator from an access point of a narrowband wireless network; Receiving access information including identification information, (b) extracting second operator identification information from the received access information, and (c) extracting the second operator identification information; If there is a match, the method may include connecting to the upper access point.

In addition, step (a) may include transmitting a probe request signal at a predetermined cycle and receiving a probe response signal including second operator identification information from an access point that receives the probe request signal.

Alternatively, step (a) may include receiving a beacon signal including the second operator identification information from the access point.

The broadband wireless network may be any one of Code Division Multiple Access (CDMA), Global System for Mobile Communication (GSM), or Time Division Multiple Access (TDMA), and the narrowband wireless network may include Wi-Fi. have.

In addition, the second operator identification information may be transmitted in a reserved field of an information element (IE) included in the beacon signal or the probe response signal.

According to the present invention, a mobile terminal connected to a broadband wireless network (e.g., CDMA, TDMA, GSM, etc.) seamlessly connects to a corresponding narrowband wireless network (e.g., WiFi network) based on the carrier identification information, thereby allowing the user to access 3G. The data communication fee can be reduced by using the network. In addition, network operators can expect to generate new profits by providing specialized services. In addition, if the WiFi network is provided by the existing 3G network provider, the user will prefer the WiFi network of the verified 3G network operator more than the private WiFi network can prevent the private WiFi network indiscriminately indiscriminate.

The broadband access module 110 is a module that enables connection to a broadband wireless network, for example, code division multiple access (CDMA), global system for mobile communication (GSM), or time division multiple access (TDMA) network. The mobile terminal 100 may access a broadband wireless network through the broadband access module 100.

The WLAN transceiver module 120 receives connection information including carrier identification information from the access point 200 of the narrowband wireless network (C). The received connection information is transmitted to the extraction module 130. In order to receive the access information including the carrier identification information, the WLAN transceiver module 120 searches for a neighboring access point 200 by an active scan method or a passive scan method. 2 to 3 are flowcharts illustrating an active scan method or a passive scan method, respectively.

Referring to the active scanning method of FIG. 2, the WLAN transceiver module 120 transmits a probe request signal for searching for an access point (200) in a predetermined cycle (step). 200). Upon receiving the probe request signal, the access point 200 transmits a probe response signal including carrier identification information to access information, such as a MAC address, to the mobile terminal 100. The active scan method is mainly used in a mobile terminal having a small battery capacity, for example, a mobile communication terminal or a personal digital assistant (PDA).

Alternatively, referring to the passive scan method of FIG. 3, the access point 200 periodically transmits a beacon signal (step 300). To this end, the WLAN transceiver module 120 must maintain a standby state for receiving a beacon signal. Like the probe response signal, the beacon signal is transmitted with the carrier identification information included in the connection information such as the MAC address. This passive scanning method is mainly used in notebook computers with a large battery capacity.

According to an embodiment of the present invention, the carrier identification information may be included in a frame body part of the IE, in particular, a reserved field for future use of the frame body part.

Referring back to FIG. 1, the extraction module 130 extracts the operator identification information from the access information received from the WLAN transceiver module 120. The extracted operator identification information is transmitted to the control module 150.

On the other hand, the storage module 140 stores one or more accessible operator identification information, which is referred to by the control module 150. The carrier identification information is information for identifying a carrier of a narrowband wireless network accessible by the mobile terminal 100, and may be, for example, an ID (VendorID) of a specific carrier.

The control module 150 refers to the storage module 140 to determine whether the operator identification information received from the extraction module 130 matches the operator identification information stored in the storage module 140. As a result of the determination, the control module 150 connects to the access point 200 based on the received access information.

Receive information. The received connection information is transmitted to the extraction module 130. On the other hand, the reception of the connection information may be by any one of the active scan method of FIG. 2 or the passive scan method of FIG.

In operation 501, the extraction module 130 extracts the operator identification information from the access information received from the WLAN transceiver module 120. The extracted operator identification information is transmitted to the control module 150.

In operation 502, the control module 150 determines whether the operator identification information received from the extraction module 130 matches the operator identification information stored in the storage module 140 with reference to the storage module 140. As a result of the determination, if there is a match, the process proceeds to step 503, and if it does not match, the process ends.

In operation 503, the control module 150 accesses the access point 200 based on the received access information when the operator identification information matches the operator identification information stored in the storage module 140.
