Description

Apparatus and method for providing personal learning information using code division multiple access broadcasting channel {An apparatus and method for providing personal learning information using the CDMA broadcasting channel}

The present invention relates to an apparatus and method for providing personal learning information using a code division multiple access broadcasting channel, and more particularly, to an apparatus for providing personal learning information to a desired person in real time using a dedicated broadcasting channel of a CDMA mobile communication. It is about a method.

The code division multiple access (CDMA) method modulates a transmission signal by assigning different codes with low correlation to each subscriber, and demodulates the transmission signal with the same code used during transmission. Because they are orthogonal, they do not affect each other. This increases line capacity because multiple subscribers can use the same frequency band for the same time.

According to the CDMA scheme, since different codes are assigned on a per-subscriber basis, confidentiality of communication is guaranteed, and digital voices can effectively accommodate non-voice services such as images and data.

The IS-95 protocol, which is such a CDMA method, cannot provide various broadcast services (eg, learning information, living information, etc.) due to the limitation of a paging channel.

That is, the current CDMA structure using the IS-95 protocol is unable to provide various services due to the limitation of channel capacity and speed.

Accordingly, the IS-2000 defines up to eight broadcast control channels (BCCHs) so that various services can be provided. This broadcast channel is a broadcast dedicated channel through a paging channel.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional circumstances, and provides a personal learning information providing apparatus using a code division multiple access broadcasting channel for transmitting learning information to a user of a desired mobile terminal in real time using a broadcasting channel. The purpose is to provide.

Hereinafter, an apparatus and method for providing personal learning information using a code division multiple access broadcasting channel according to an embodiment of the present invention will be described with reference to the accompanying drawings.

1 is a network configuration diagram to which an apparatus for providing personalized learning information using a code division multiple access broadcasting channel according to an embodiment of the present invention is applied, comprising: an information provider 10 for providing various learning information; A broadcast control service center 12 which manages a broadcast channel and outputs a message related to various learning information transmitted from the information provider 10 through a broadcast channel managing the broadcast channel; A visitor location register (14) for constructing a subscriber's call path and storing temporary information of the subscriber station and a subscriber station for establishing a connection with another communication network; Travel through a control station and antenna 18 coupled to the switching center / subscriber locator 14, controlling the wireless link and the wired link, and performing a handoff function for maintaining the continuity of the call while the subscriber is moving. A base station 16 performing communication using a wireless section together with the terminal 20; A public switched telephone network (PSTN) 22 connected to the switching center / visitor location register 14; An interworking function unit 24 for wirelessly connecting the switching center / visitor location register 14 and the Internet 26; A home location register 28 that stores subscriber information (e.g., mobile phone number, terminal serial number, supplementary service type, charge status, etc.); A message center 30 for providing a subscriber with various messages related to learning information; And an SMS server 32 in which the subscriber transmits a short message service (SMS) through the Internet 34 in association with the message center 30.

In the above arrangement, when a telephone call is made through the public switched telephone network 22, the switching center 14 queries the subscriber based on the information in the home location register 28. In this case, the subscriber information used is a mobile phone number, a terminal serial number, an additional service type, a charge status, and the like.

If the call is a normal voice call, the exchange station 14 transmits the message to the mobile terminal 20 of the called party through the control station / base station 16 when it is determined that the subscriber is a normal subscriber.

The broadcast control service center 12 transmits the learning information content to the exchange / visitor subscriber location register 14 in the form of a predetermined message provided by the information provider 10, and the exchange / visitor subscriber location register 14 The content of the learning information in the form of the received message is transmitted to all the mobile terminals 20 including the receiving station via the control station / base station 16.

Meanwhile, in FIG. 1, the forward channel (based on the content defined in IS-2000) includes a pilot channel, a sync channel, a quick paging channel, and a broadcast channel. (broadcast control channel), common control channel (common control channel), traffic channel (traffic channel), supplemental channel (supplemental channel) and the like.

In FIG. 1, the reverse channel includes a reverse pilot channel, an enhanced access channel, a traffic channel, a reverse common control channel, and a supplementary channel. And a supplemental channel.

The broadcast channel (BCCH) has a delimiter for distinguishing each service, thereby distinguishing learning information and other services.

The broadcast control service center 12 transmits learning information through a communication channel using a communication channel as a broadcast channel when the subscriber's terminal is busy, and sets a paging channel when the subscriber's terminal is busy. It transmits learning information through the paging channel as a broadcasting channel.

In the configuration of FIG. 1, a method using a point-to-point SMS or a method using wireless data is used for subscriber control.

First, according to a method of controlling subscriber learning information using SMS, when a subscriber selects a service corresponding to the Internet 34, the service selection signal is transmitted to the message center 30 via the SMS server 32. . The SMS server 32 is simply a service for interworking the message center 30 and external equipment, and the SMS data transmitted to the mobile terminal 20 is transmitted from the message center 30. The message center 30 is a system component for processing SMS in a conventional radio section protocol and is a very advantageous protocol for simple message transmission in a point-to-point manner.

On the other hand, in the case of using wireless data through the interworking function unit 24, subscriber control information can be set to the Internet 26, similar to SMS. At this time, the subscriber's mobile terminal 20 should be able to process wireless data.

The home location register 28 stores information on whether and how a subscriber registers learning information service. Accordingly, in the case of controlling the learning information of the subscriber through the Internet 26 or 34, the subscriber's inquiry of the home location register 28 is made first, and then the subscriber's mobile terminal (through the exchange / visitor location register 14). 20).

The actual learning information of the subscriber transmitted by the information provider 10 to the broadcast control service center 12 is predetermined content and a code based on the same.

That is, the actual learning information content is transmitted to the mobile terminal 20 in the format as shown in Table 1 below.

<Table 1> Learning Information Message Structure

division Number of bytes Explanation Header Grade division One Grade separator code Service item 2 Service item (large item) Detail service item 2 Detailed Service Items (Small Items) contents Actual data n Actual data

In Table 1, the learning information message is composed of actual data and a header. The header consists of 5 bytes, and the actual learning information content is located after the header.

The header is actually sent in the form of a code, the content of which is sent in a learning information control message. The actual learning information message and the learning information control message are transmitted through a broadcast channel. If the header information is changed, the corresponding code is also changed.

The learning information control message is a message for controlling the header information of the learning information message, and its structure is as shown in Table 2 below, and the mobile terminal 20 transmits the received learning information control message to an internal inactive memory. Save and process.

<Table 2> Structure of learning information control message

Transmission order Number of bytes Explanation Information code One '00000000' Grade separator code One Grade separator code Content 1 8 Grade Description Service item code 2 Service item code Content 2 10 Description of the service item (for example, learn today) Detailed service item code 2 Detailed service item code Content 3 14 Detailed service item description (for example, national language)

The learning information control message of <Table 2> uses "0000 0000" as a code for distinguishing from the actual learning information message, and then the control information is transmitted. That is, the grade classification code consisting of 1 byte is transmitted after the information classification code of 1 byte, and the content (content 1) of the grade classification code is described by 8 bytes. For example, when "0000 0001" is transmitted to the grade code, "1st grade" is transmitted to the content 1.

Next, a service item code of 2 bytes is constructed. This service item code is also composed of the code, not the content of the item displayed as the actual completion code. The actual content (content 2) of this is 10 bytes, which is 5 Korean characters. For example, if the service item code is set to "0000 0000 1111 1111", the content 2 is configured as "learning information".

Finally, two byte detailed service item codes are constructed. The content (content 3) of this detailed service item code consists of 14 bytes of Korean seven digits. For example, if the detailed service item code is set to "0000 1111 0000 1111", the content 3 is configured as "Korean deep learning."

Meanwhile, the learning information registration message is transmitted to the mobile terminal 20 using SMS or wireless data. The learning information registration message may be made through the Internet or by voice guidance in order for the subscriber to easily register.

The learning information registration message set up as described above has a message structure as shown in Table 3 below when it is made through point-to-point SMS or wireless data.

<Table 3> Learning Information Registration Message Structure

Control items Control code (1 byte) Detailed control code (2 bytes) Explanation Learning Information Enable - 00 Activate all learning information Learning Information Disabled // 11 Disable all learning information Corresponding service item -/ Xx Activate the service item Off the service item /- Xx Stop the service item

When the learning information registration message of <Table 3> is made for an individual subscriber, when using SMS, a separate SMS application service identifier, TI (Teleservice Identifier) is used. For example, in order to register learning information to a corresponding subscriber, it is transmitted in the order of "control code-detailed control code" using the individual subscriber's telephone number. In <Table 3>, the control code and the detailed control code are based on an ASCII code.

The subscriber's mobile terminal 20 stores the learning information registration message of the above structure in an inactive memory and processes the learning information message received through the broadcast channel.

2 is a flowchart illustrating a procedure of transmitting personal learning information to a mobile terminal using a broadcast channel.

First, when the information provider (IP) 10 sends a signal requesting transmission of learning information to the broadcast control service center 12, the broadcast control service center 12 sends the learning information transmission request signal to the switching center 14. .

The exchange station 14 sends a response signal (ACK) indicating normal transmission permission to the broadcast control service center 12, and the broadcast control service center 12 sends the response signal to the information provider 10. .

Accordingly, the information provider 10 receiving the response signal transmits the corresponding learning information to the broadcast control service center 12, and the broadcast control service center 12 transmits its contents to the switching center 14, The switching center 14 sends the learning information to the control station / base station 16, so that the learning information is transmitted to the mobile terminal 20 of all the subscribers which can be received via the radio section.

In this case, the broadcast channel is a unidirectional broadcast dedicated channel and thus does not require a response. When the control station / base station 16 transmits a normal signal to all the subscriber's mobile terminals (including 20), the control station / base station 16 transmits a signal indicating completion of the transmission to the information provider (via the exchange station 14 and the broadcast control service center 12). 10) to send.

3 is a flowchart illustrating a procedure of processing a personal learning information registration message performed in the apparatus of the present invention.

When the subscriber sets the personal learning information registration contents through the Internet, the information change request signal is transmitted to the message center 30 through the SMS server 32. The message center 30 inquires the subscriber to the home location register 26 to check the status of the subscriber and the contents of the learning service subscribed.

If it is determined that the home location register 26 is a normal subscriber, its contents are transmitted to the SMS server 32 through the message center 30 and immediately send a response to the Internet.

Accordingly, when the subscriber who has received the response signal ACK changes the information through the Internet, the SMS server 32 and the message center 30 transmit the changed information via the switching station 14 to the control station / base station. 16), the changed information is immediately transmitted to the mobile terminal 20 to process the learning information registration.

The control station / base station 16 transmits the changed information to the mobile terminal 20 and then transmits a transmission completion signal to the switching center 14, which transmits the transmission completion signal to the message center 30. Send to the SMS server 32 and immediately notify the completion of the transmission to the Internet.

As described in detail above, according to the present invention, the subscriber's registration information is controlled using SMS to provide the subscriber's learning information, and the actual contents are transmitted through a broadcast channel, thereby serving a large number of subscribers without significant effect on system capacity. Can be.

In addition, it is expected that additional services using broadcast channels will be diversified in the future, thereby maximizing its use, and not only providing actual student-oriented learning information but also providing other specialized services.
