Description

Method for origination message service in mobile station using string}

The present invention relates to an outgoing service method of a mobile communication terminal, and more particularly, a mobile communication through a character string to be received by a corresponding recipient connected to the character string when a transmission operation is made to a mobile communication terminal by a specific character string using ASCII characters. The present invention relates to a calling service method of a terminal.

Recently, additional services such as e-mail as well as additional services such as weather, traffic information, and home banking are rapidly provided, and a call button is stored with a plurality of phone numbers stored in a predetermined memory. Depending on the operation of the call path is automatically made.

That is, when a specific receiver is to be sent using a predetermined mobile terminal, it is possible by manipulating the numbers 0 to 9 and specific characters '#' and '*' on the keypad provided on the mobile terminal. In this case, the numbers or letters to be manipulated are converted to 4-bit dual tone multi frequency (DTMF) codes to form the entire telephone number to be sent.

Then, the telephone number generated by the method as described above is shown in the block diagram showing the originating service procedure of the mobile communication terminal according to the prior art of Fig. 1, the mobile terminal 10 that generated the telephone number first Is transmitted to the base station 20 by using an outgoing message transmitted through the access channel of the CDMA air interface, and then the subscriber parameters and the location information are transmitted through the base station controller 30 and the mobile switching center 40. A call path is established through the provided subscriber information processor (HLR) 50.

At this time, in order to indicate that the 4-bit DTMF code has been converted, the digit-mode field value of the field value of the outgoing message is set to 0.

On the other hand, if the entire telephone number to be transmitted through the outgoing message cannot be transmitted, the remaining number is transmitted using an Origination Continuation Message through a reverse traffic channel.

That is, the process of connecting a call with a receiver to be received according to the outgoing message access procedure as described above is a call connection only to the corresponding telephone number pressed through the outgoing operation using the DTMF code.

However, as described above, the outgoing service by the mobile communication terminal can only perform the access function by the numbers 0 to 9 and the specific characters '#' and '*' provided on the keypad of the mobile communication terminal. If the caller does not know the telephone number of the receiver that he wants to access, there is a problem that the call cannot be connected to the receiver.

The present invention was created to improve the above problems, and provides a call service by using a pre-stored string even when the caller does not know the telephone number of the receiver to which the caller wants to connect. It is an object of the present invention to provide a call service method of a mobile communication terminal through a string to maximize the variety of call methods, such as providing a call service by a string as well as a number and letters provided on the keypad of the city mobile communication terminal.

Selecting a phone number, determining a call destination according to the selected phone number, and if the call destination is a general universal phone number from the determining step, performs a call connection with the phone number, and performs a WAP (Wireless Application Protocol). If it is a connection, it includes the step of performing a connection with any Internet site.

Preferably, the outgoing message is characterized in that the digit mode field value is set to 1 to perform an outgoing function using ASCII characters.

Preferably, if the transmission of the outgoing message is not carried out, characterized in that for transmitting using the outgoing sustain message.

In addition, the apparatus employed in the originating service method of the mobile communication terminal through the character string according to the present invention for achieving the above object, receives the character string by the user interface and stores it in a predetermined memory, and generates an outgoing message when performing the outgoing A mobile phone terminal to be transmitted, and a telephone call corresponding to the string from a wireless incoming phone book which receives the inputted character string from the mobile communication terminal through a base station and stores a plurality of telephone numbers for a category to which a specific character string belongs. And a subscriber information processor for retrieving the number and performing a call connection with the retrieved telephone number.

Preferably, the mobile communication terminal generates an outgoing message in which the digit mode field value is set to 1 to perform an outgoing function using ASCII characters.

Preferably, the HLR searches for the outgoing message and determines whether a general universal telephone number or a WAP access is made according to the search result.

According to the outgoing service method of the mobile communication terminal through the string of the present invention, when the caller transmits the outgoing message by the string even when the caller does not know the phone number to be connected, the phone number mapped to the outgoing message is selected and connected. Can be.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 2 is a block diagram illustrating an apparatus employed in an outgoing service method of a mobile communication terminal through a character string according to the present invention. As shown in FIG. And a mobile communication terminal 100 for generating an outgoing message in which the digit mode field value is set to 1 so that transmission can be performed using ASCII characters when performing the transmission, and access of the CDMA radio interface from the mobile communication terminal 100. The base station 110 receives the outgoing message through a channel, and receives the outgoing message from the base station 110 through the base station controller 120 and the mobile switching station 130, and the category belongs to various categories. A subscriber information processor (HLR) 140 having a wireless called directory 150 which stores two telephone numbers, A data network interlocking unit (IWF) for performing a wireless data service function in a wireless application protocol (WAP) connection environment through a router 170 in association with a mobile communication terminal as a data network interlocking device according to the determination of the call destination of the HLR 140; Inter Working Function) 160.

Here, the reference numeral 170 is a router for interconnecting the data network interworking unit 160 and the wireless application protocol connection environment using a relay function of the network layer.

Referring to the operation of the originating service control device of the mobile communication terminal through the string configured as described above are as follows.

First, the mobile communication terminal 100 receives a character set under a user interface environment so as to provide an outgoing service using various characters and strings other than the existing letters or numbers, and stores them in a predetermined memory (step) 200). Here, the mobile communication terminal 100 sets the field value of the digit mode of the outgoing message to 1 so that the outgoing message generated when the stored text is transmitted can be transmitted by ASCII characters.

From the above state, when the caller searches for and selects a string of the other party to be connected through the display unit of the mobile communication terminal 100 and manipulates an outgoing service key, an outgoing message for the selected string is generated and the CDMA wireless interface is accessed. A channel is transmitted to the base station 110, and the base station 110 transmits the outgoing message to the HLR 140 to retrieve the transmitted telephone number (step 210) (step 220).

At this time, if it is impossible to transmit the entire message to be transmitted through the outgoing message (NO in step 230), the remaining number is transmitted by using an Origination Continuation Message sent through the reverse call channel ( Step 240).

Subsequently, the HLR 140 searches for the received outgoing message, and the searching operation is performed through the wireless incoming phone book 150 in which several telephone numbers are stored for a category belonging to a specific string ( Step 250). That is, the wireless terminating phone book 150 stores a service company that a mobile communication service provider wants to register, and defines a main category such as types of restaurants, securities branches, government offices, shopping malls, and reservation agents, respectively. Phone number retrieval is designed to retrieve a wireless incoming phone book stored in a tree structure from the above main category, as specifying the sub category subordinate to the category in detail.

When the HLR 140 finds a phone number for the outgoing message transmitted from the mobile communication terminal 100 from the wireless destination phone book 150 (step 260), the call destination is determined according to the selected phone number. That is, it is determined whether the called party should perform a general universal phone number or WAP connection (step 270).

In this case, in the case of a general universal phone number (Yes in step 280), the phone number and the call are connected, for example, the mobile communication terminal 100 uses a character string of pizza restaurant in the restaurant category. When the call is made by including an attribute to connect the closest location to the location of the HLR 150, the HLR 150 selects the phone number closest to the current location of the mobile communication terminal 100 as the call destination (step 290). .

On the other hand, if the destination is the address of the Internet site (NO in step 280), the HLR 150 selects the Internet site address, which is the character string, as the destination and the Internet site through the wireless data service interworking unit 160. A connection is made to the address (step 300, step 310).

In other words, the outgoing service method of the mobile communication terminal through the string is to connect the incoming target on the wireless destination phone book mapped to the specific string through the outgoing operation using the string.

As described above, according to the calling service method of the mobile communication terminal through the character string of the present invention, the user of the mobile communication terminal can search for / select the corresponding phone number from the wireless destination phone even without knowing the telephone number of the person to be called. The effect is that you can try to connect.

In addition, when using the Internet service, there is another effect that can try to access the site by directly input any desired address.
