This will be described in detail.

3 is a detailed block diagram of the wireless Internet service (WIS) block shown in FIG. 2, and includes a main processor 302, a DPRAM 304, a FIFO 306, and an interface block 308.

Referring to FIG. 3, the main processor 302 moves in a reception mode in which data is received from a router in a state in which web site related information, for example, the Internet is connected (call setup), from the router shown in FIG. In response to a request for an initial menu screen data for an Internet service from a terminal, initial menu screen data (Ethernet data) received through a router or website information data (Ethernet data) provided from a router in response to a subscriber request is received. Converts the received Ethernet data into HDLC data and stores the received Ethernet data at a predetermined address of DPRAM 304 through line L31, generates a received message indicating that the data has been received, and delivers the received message to interface block 308 through line L32. do.

In addition, the main processor 302 notifies the reception message from the interface block 308 in the transmission mode of transmitting data to the router, that is, the channel information stored in the FIFO 306 via the line L33. (I.e., information indicating which of 32 channels have transmission data), and based on the search result, data (HDLC data) stored at a predetermined address of the DPRAM 304 is extracted and converted into Ethernet data. Send to router

That is, the main processor 302 converts the Web site related information data of the Ethernet format received from the router in the reception mode into HDLC data and stores it in the DPRAM 304, and stores the HDLC stored in the DPRAM 304 in the transmission mode. The data in the format is converted into Ethernet data and transmitted to the router.

On the other hand, the interface block 308 receives the information stored in the DPRAM 304 based on the received message provided through the line L32 in the reception mode of transmitting the website related information provided from the router to the mobile terminal that requested the Internet service. The data is retrieved and transferred to the time switching block 208 of FIG. 2, that is, the received data (e.g., initial screen data, website information data, and the like) is distributed to two channels (64 Kbps for each channel) to allocate channels. It then passes through the two assigned channels to the time switching block 208 of FIG.

That is, in the interface block 308, unlike the conventional method of transmitting the received data to the base station (BS) at a transmission rate of 64 Kbps through one assigned channel, transmitting the received data to the corresponding base station through the two allocated channels. Therefore, the result is that the received data is transmitted at a transmission rate of 128 Kbps, thereby enabling the provision of Internet service about twice as fast as the conventional method.

The interface block 308 also includes two channels (one channel 64 Kbps) provided from the time switching block 208 of FIG. 2 in a transmission mode in which data (HDLC data) generated in a mobile terminal is received and transmitted to a router. Maps the data of the data to one channel (128Kbps) and stores it in the DPRAM 304 through the line L35, and generates a received message indicating that the data to be transmitted is received and passes it to the main processor 302 through the line L32. Furthermore, channel information (that is, information indicating which of 32 channels have data to be transmitted) is generated on the line L34 and stored in the FIFO 306.

That is, in the interface block 308, the reception data (converted HDLC data) drawn from the DPRAM 304 is divided into two channels in the reception mode, the channel is allocated, and then transferred to the time switching block 208 of FIG. In the transmission mode, data of two channels provided via the time switching block 208 of FIG. 2 is channel mapped at 128 Kbps and stored in the DPRAM 304 and notified to the main processor 302.

Therefore, the wireless Internet service block 210 in the base station controller (RNC) through the above-described process, provides a high-speed Internet service between the base station (that is, the mobile terminal) via the router and the Internet network.

Next, a process of providing a high speed internet access service according to the present invention using a wireless internet service apparatus in a base station controller having the above-described configuration will be described.

4 is a flowchart illustrating a process of providing an Internet service at a high speed to an broadband wireless mobile terminal (IMT-2000) in a base station controller according to a preferred embodiment of the present invention.

Referring to FIG. 4, if any registered subscriber mobile terminal (MS) requests an Internet access service while performing a standby mode (call waiting or reception waiting) (step 402), an Internet access service request signal corresponding thereto is requested. Is transmitted to the base station (BS), and when the base station (BS) receives the Internet access service request signal from the mobile terminal (MS) in its service area (step 404), it generates an Internet connection request message corresponding thereto. To the base station controller (RNC).

Accordingly, the base station controller (RNC) establishes a call through message exchange with the wireless Internet service block 210 in charge of the Internet access service, that is, the base station interface block 202 ↔ inter processor communication block 204 shown in FIG. Call processing is performed through a message exchange between the RNC main processor block 206 and the wireless Internet service block 210 to establish a call between the mobile terminal, the base station, the base station controller, and the Internet network that requested the service (step 406). . At this time, two channels among 32 channels are allocated to call setup to provide Internet service.

As described above, a request signal for the initial menu screen information for the Internet service is generated from the mobile terminal in a state in which a call for the Internet access service is set, and the wireless Internet service block in the base station controller RNC is transmitted through the base station BS. 210 (ie, stored in DPRAM 304 of FIG. 3), the main processor 302 in the wireless Internet service block 210 provides initial menu screen data (Ethernet format data) from the Internet via a router. Take it, convert it to HDLC data, store it at a predetermined address in DPRAM 304, generate a receive message on line L32, and provide it to interface block 308 (step 408).

Next, in the interface block 308, based on the received message provided from the main processor 302 via the line L32, the received data (converted HDLC data) stored at a predetermined address of the DPRAM 304 is fetched, and The received reception data (i.e., initial menu screen data) is distributed to two allocated channels (64 Kbps for each channel) for channel allocation, and then the time switching block 208 of FIG. (Step 410).

Accordingly, according to the Internet service method according to the present invention, unlike the conventional method of transmitting the received data to the base station (BS) at a transmission rate of 64 Kbps through one allocated channel, two channels are allocated and two received data are allocated. Since the transmission to the base station (BS) through the channel is a result of transmitting the received data at a transmission rate of 128Kbps substantially can provide an Internet service about twice as fast as the conventional method.

On the other hand, in the present invention, when the mobile terminal requests the initial menu screen for the Internet service through the steps 408 and 410, the base station controller receives initial menu screen data through the router and transmits the initial menu screen data to the mobile terminal. Although described above, if the initial terminal screen data for the Internet service is pre-stored on the mobile terminal side, the above two steps 408 and 410 are omitted, and the process goes from step 406 to step 412. It proceeds immediately.

As a result, the initial menu screen data distributed through the two channels is transmitted from the base station controller (RNC) to the mobile terminal (MS) that has requested the Internet service through the base station (BS), so that the Internet service is displayed on the monitor of the mobile terminal (MS). The initial menu screen for is displayed (step 412).

As described above, the state in which the initial menu screen is displayed on the monitor of the mobile terminal MS may be referred to as a website information request standby mode. In this standby mode, when the user requests arbitrary website information, In step 414, in response to the information request signal, the base station BS distributes the corresponding web site information request message through two previously allocated channels and transmits the same to the base station controller RNC (step 416).

Therefore, the wireless Internet service block 210 in the base station controller (RNC) synchronizes the website information request message for two channels (each 64 Kbps) provided through the base station interface block 202 and the time switching block 208. Maps to one channel (128 Kbps), stores it at a given address in DPRAM 304, generates a receive message indicating that the data to be transmitted has been received, and delivers it to the main processor 302 via line L32 on line L34. Channel information (i.e., information indicating which of 32 channels have data to be transmitted) is generated and stored in the FIFO 306 (step 418).

Next, the main processor 302 searches for channel information stored in the FIFO 306 via line L33 when a received message is sent from the interface block 308 via L32, and based on the search result, the DPRAM 304 It extracts the data (HDLC data) stored at the predetermined address of the data, converts it into Ethernet data, and transmits it to the router, that is, requests the web site information according to the user's request from the Internet network. When the website information (Ethernet format data) requested by the subscriber (or user) is received, the received Ethernet data is converted into HDLC data, and then stored in the predetermined address of the DPRAM 304 via the line L31, and the data is received. The notifier generates a received message and passes it to interface block 308 over line L32 (step 420).

The interface block 308 then fetches website information data (converted HDLC data) stored at a predetermined address of the DPRAM 304 based on the received message provided from the main processor 302 via the line L32, The fetched web site information data is distributed to two pre-allocated channels (64 Kbps for each channel), allocated to the channel, and then transmitted to the base station BS through the two channels (step 422). That is, in the Internet service method according to the present invention, unlike the conventional method of transmitting the received data to the base station (BS) at a transmission rate of 64 Kbps through one assigned channel, the web site information data through the two channels previously allocated. The web site information data received from the router is transmitted to the base station BS, i.e., at a transmission rate of substantially 128 Kbps.

As a result, the website information data is transmitted to the mobile terminal MS, which has requested the website information through the base station controller RNC and the corresponding base station BS, so that the subscriber (or user) requested on the monitor of the mobile terminal MS is requested. The website information screen is displayed (step 424).

Accordingly, the present invention provides a high-speed Internet service to a broadband wireless mobile terminal using two occupied channels allocated through the above-described process.

As described above, according to the present invention, when requesting Internet service using a broadband wireless mobile terminal (also called IMT-2000), two channels are allocated (occupied by two channels) to the base station and the base station control period, Since the Internet service related information is interfaced between the base station and the base station control period by using two occupied channels, it is possible to realize approximately twice the speed as compared with the conventional method of interfacing data using only one channel as described above. .
