3 is a block diagram schematically illustrating a system for providing an incoming service to the portable Internet according to a preferred embodiment of the present invention.

The portable Internet receiving system for providing the incoming service to the portable Internet according to the present invention further includes an interworking terminating server 320 and a complex terminal information DB 330 in an interworking system of the mobile communication system and the portable internet system. Here, in the mobile communication system and the portable Internet system, the mobile communication IP network 140 and the IP network 230 connected through the router 150 are interworked through the router 150, and the HA 160 and the AAA 170 are connected to each other. Is shared. Here, the HA 160 and the AAA 170 may be included in the mobile communication system and the portable Internet system, respectively.

In addition, the portable Internet receiving system according to the present invention includes a composite terminal 310 including both the functions of the mobile communication terminal 110 and the portable terminal 120. The composite terminal 310 is a terminal capable of receiving a voice call service through a mobile communication network and a portable internet service through a portable internet network. The composite terminal 310 is a MM-MB (Multi Mode-Multi Band) terminal supporting two or more systems. In order to receive a voice call service, the composite terminal 310 is connected to a mobile communication network using a mobile communication modem and provides a mobile Internet service. In order to receive it, the mobile internet modem is connected to the mobile internet modem. In general, when using a mobile communication modem, the portable Internet modem is not used, and when using a portable Internet modem, the mobile communication modem is not used. However, it is also possible to simultaneously receive both voice call service and portable Internet service by using both a mobile communication modem and a portable internet modem.

The interworking destination server 320 is a server that stores subscriber information and information of the composite terminal 310. Here, the subscriber information includes whether the terminal used by the subscriber who is provided with the portable Internet service is the composite terminal 310 and the type of service provided. The composite terminal information includes the mobile communication identifier of the composite terminal 310 and the wireless. It contains information such as the identifier for the Internet connection and the terminal type. Here, the interworking destination server 320 may be configured to check the subscriber information from the HLR 128 in cooperation with the HLR 128 of the mobile communication system without storing the subscriber information.

The interworking destination server 320 matches the mobile communication identifier of the composite terminal 310 with the identifier for the wireless Internet connection, stores the mixed terminal information database 330, and requests the information of the composite terminal 310 from the IP network 230. If there is, it is responsible for providing the mobile communication identifier information of the corresponding composite terminal 310 to the IP network 230.

The composite terminal information database 330 is a part for storing information of the composite terminal 310 through the interworking destination server 320. The composite terminal information database 330 may store subscriber information in addition to the information of the composite terminal 310.

The composite terminal information database 330 may be included in the interlocked terminating server 320 according to the setting. As described above, when the interlocked terminating server 320 receives subscriber information from the HLR 128, the composite terminal information. Since the function of the database 330 is performed by the HLR 128, it may be omitted.

4 is a flowchart illustrating a method of receiving a call to the portable Internet according to a preferred embodiment of the present invention.

First, the interworking destination server 320 obtains the information of the composite terminal 310 of the users of the portable Internet incoming service, and stores the information in the composite terminal information database 330. The internet network 180 generates a data incoming request signal according to an e-mail reception or a multimedia message reception to the terminal in the standby mode. Here, when the incoming call request terminal is the composite terminal 310, the data incoming request signal should include an identifier for wireless Internet access (S402).

In the IP network 230 that receives the data incoming request signal from the Internet network 180, the information regarding the terminal for which data is requested is checked using the interworking destination server 320. That is, the interworking destination server 320 checks whether or not the terminal requested for data reception is the composite terminal through the composite terminal information database 330 in which the information of the terminal is stored (S404), and determines that the composite terminal 310 is present. The identifier for mobile communication matched to the identifier for wireless internet access of the composite terminal 310 is checked (S406).

When the identifier for the mobile communication is confirmed, the interworking destination server 320 transmits the mobile communication identifier to the mobile communication switching center 126 of the mobile communication network through the mobile communication IP network 140 (S408), and the mobile communication switching center 126 transmits the transmission. The area where the composite terminal 310 having the mobile communication identifier is located is identified through a visitor location register (VLR). When the region where the hybrid terminal 310 is located is identified, a paging message containing information indicating that there is a data call request signal from the Internet is generated through the base station controller 124 and the base station transmitter 122 of the region. Here, the paging message is a message indicating that a voice call or a data call has arrived to the composite terminal 310 through the mobile communication network 120, and is one of a plurality of messages transmitted to the composite terminal 310 through a paging channel among wireless channels.

In general, a paging message is composed of a message length field, a message content field, and a cyclic redundancy check (CRC) field. In accordance with the present invention, a message content field stores a content request signal from the Internet network. Here, the CRC field is a field for performing error detection for verifying the reliability of data.

In addition, the paging message according to the present invention may further include a new field in the conventional paging message structure to store information indicating that there is a data incoming request signal from the Internet. That is, a data incoming request signal may be created in a reserved field that is configured to add new data to a paging message, and the generated field may include content including data incoming request signal information. By setting the field, information indicating that there is a data call request signal from the Internet network may be set to be stored (S410).                     

When the paging message is generated, the mobile communication network 120 transmits the generated paging message to the composite terminal 310. Here, according to the present invention, transmitting the paging message including the data incoming request signal to the composite terminal 310 through the base station transmitter 122 in the mobile communication network 120 is called a paging function (S412).

Upon receiving the paging message, the hybrid terminal 310 changes the operation mode set to the mobile communication operation mode to the portable Internet operation mode according to the data incoming request signal. Here, when the composite terminal 310 is set to the portable Internet operation mode instead of the mobile communication operation mode, the process of changing the operation mode is not performed separately (S414).

The composite terminal 310 set to the portable internet operation mode connects to the portable internet network 220 through a session setup with the portable internet network 220, and the data transmitted by the internet network 180 through the IP network 230. It receives (S416).

In this case, when the incoming call request terminal is not the composite terminal 310, it may be notified to transmit data through the mobile communication network 120. In order to execute such a method, when it is determined in step S404 whether or not the composite terminal 310 is determined by the interlocked terminating server 320 of the terminal requested to be interlocked, the interlocked terminating server 320 is requested. A message indicating that data is to be transmitted through the mobile communication network 120 together with the mobile communication identifier of the terminal is transmitted to the mobile communication switching center 126 (S418).

The mobile communication switching center 126 checks the transmitted mobile communication identifier, and then confirms the position of the terminal through the VLR. When the location of the terminal is confirmed, a wireless internet access request message for informing a request for access to the wireless internet through the mobile communication network 120 is generated. Here, the short message, voice message, MMS (Multi-Media Message Service) message, etc. may be used as the wireless Internet access request message (S420).

The terminal receiving the wireless Internet access request message accesses the mobile communication IP network 140 through the PDSN 130 of the mobile communication network 120 and receives data from the Internet network 180 (S422).

However, if it is determined in step S404 that the called terminal is not the composite terminal 310, it is also possible to set to terminate immediately without performing the step S418 to S422 described above, that is, without performing the call notification process. Do.

In the above description, the 1x EV-DO network has been described as a mobile communication system interworking with the portable Internet system. However, the present invention may be implemented in IS-95, CDMA2000 1X, WCDMA, GSM, and 1x EV-DV systems. In the description of the present invention, the portable Internet network has been described as a portable Internet system. However, the present invention may be implemented in a WLAN system.
