BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a text receiving display device in a wireless call receiver, and more particularly, to an apparatus and method for distinguishing a type of received information and displaying a specific text or picture accordingly. According to US Pat. No. 4,412,217, a counter is incremented and displayed according to the number of pages received.

According to US Pat. No. 5,317,621 (multi-address radio display pager), a method of checking whether a received message includes a specific identifier and displaying a pre-stored message when the identifier is detected is disclosed. The wireless call receiver with a numeric reception function mainly receives only a phone number, but the text receiver pager provides not only a phone number but also a call message and various living information. Therefore, text receiving pagers usually receive four different types of information services to meet these needs.

In the character receiver radio call receiver, this division is simply indicated as address 1, address 2, address 3, address 4, etc. based on the address, or as numbers 1, 2, 3, and 4, and statistical values of data received at each address are displayed. It is displaying. Since this is a developer-oriented display method, from the user's point of view, it is impossible to know what kind of information is actually received. In addition, it was very inconvenient because the results of various searches for the received information could not be displayed or statistically generated according to the type of information.

Accordingly, an object of the present invention is to provide a text receiving display apparatus and method for displaying a call message received at a wireless call receiver according to the type of information and displaying the call message.

Another object of the present invention is to provide a text receiving display apparatus and method for displaying the results according to the type of information or performing statistics when searching for various types of information received from a wireless call receiver. In order to achieve the above object, the present character reception display apparatus includes: a decoder for decoding a received call message and detecting an address corresponding to the cap code and a predetermined function bit in a wireless call receiver having a plurality of cap codes; A memory for storing an information classification table and icon data corresponding to each information classification and a received call message, an information classification corresponding to the detected address and a function bit according to the information classification table, and the received call message A central processing unit storing the icon data in the corresponding area of the memory based on the found information classification and finding icon data from the memory based on the found information classification, and receiving the icon data from the central processing device. It is characterized by.

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

In the following description, numerous specific details such as components of specific circuits are shown, which are provided to aid a more general understanding of the present invention, and it is understood that the present invention may be practiced without these specific details. It will be self-evident to those of ordinary knowledge. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

'Ho line message' described in this embodiment includes not only a phone number but also a call message and various life information.

1 is a configuration diagram of a radio call receiver to which the present invention is applied. The receiver 11 receives a radio call message and performs functions such as frequency conversion, demodulation, and waveform shaping. The radio call information converted into the digital form by the receiver 11 is applied to the decoder 12. The decoder 12 decodes the received data and sets an operation mode of the radio call receiver. That is, in the idle mode, the supply of the operating power is controlled at regular intervals to detect the preamble data, and in the batch mode, the word sync data and the set frame data are detected. The detected frame data is decoded and converted into the original data form. The controller 13 receives the decoded data output from the decoder 12. The controller 13 processes the received data to control an alarm function. The alarm unit 17 generates an alarm signal such as a tone signal or a vibration signal for notifying that the alarm signal has been called by the alarm control signal output from the controller 13. The display unit 16 subdivides the message of the calling party and the status information of the wireless call receiver by the display control signal outputted from the control unit 13 and displays the message or icon in detail. The memory 15 stores unique address data, frame data, information classification table, icon data, and the like allocated to the radio receiver, and may use an E ² PROM.

Figure 2 shows the form of the POCSAG code used in radio call receivers, which is currently available worldwide in the form of dedicated pager signals and is detailed in CCIR Recommendation 584. One POCSAG code consists of preamble data consisting of 576 bits and a plurality of batch data contiguous. The preamble data is a code in which 1 and 0 are repeated for 576 bits. The one POCSAG code usually consists of 30 batches up to 60 batches. One batch consists of one wordsync data of 32 bits and eight frame data of 64 bits. The word sync data is 32-bit data of (7CD215D8) H and (01111100 11010010000101011101100) B. Each frame data is composed of 32 bits of address codeword and 32 bits of message codeword. Therefore, one batch is composed of 17 words of 544 bit data (17 words * 32 bits = 544 bits) in which 32 bits of data are one word.

3 is a flowchart illustrating a text reception display process of a wireless page receiver according to an embodiment of the present invention. There are three general categories of service information. One is to use a different address directly, and the other is to use the same address but use different function bits. The former is mainly used when different service providers are used, and the latter is mainly used when one service provider is serving different pieces of information at the same time. Another method is to distinguish by adding a specific code to a message of the same address and detecting it.

As a second example of the three methods described above, up to four addressable addresses of the pager are usually used. In this case, one is used for personal calling and the other three are used for receiving information. The following table 1 shows the cases in which they can occur.

As described above, since four function bits are provided for each of four addresses, 16 types of information can be received.

However, if we assume that this kind of information is processed in three addresses, except for the first address, we can process a total of twelve pieces of information. Assume that the user stores the following Table 2 information in internal or external memory. In other words, it is assumed that the user wants to display the following six pieces of information.

The following is an example of ROM-writing information. If you interpret this,

2-1234567-03 -6-1

2: It indicates that it corresponds to the second cap code among a plurality of cap codes (eg, 4) that the paging receiver may have.

1234567: actual capcode content

03: Function Bit

6: sports

1: First display position

It has the above data in the external memory or internal memory, and based on this data, the processing method is searched with the data (address and function bits) sent from the decoder. The method is as follows.

Find the value in Table 2 above with the values of the address and function bits received from the decoder. If the function bit is 1 in address 1, it is determined to be general call data. If the function bit is 1 in address 2, this data corresponds to news, and each processing routine is followed. In order to display such information by type, the storage, deletion, and the like of the received message are operated with a separate content of managing a memory area RAM storing additional information as shown in FIG. The message storage area is divided into call, news, stock, weather forecast, horse racing, and sports, respectively, and the number of messages received so far with the MTP (Message Table Pointer) and MTS (Message Table Start), and the order of received messages. The location of the received message.

Here, MTP refers to a start address according to the type of information to be stored when a message is received, and MTS actually indicates the start of an address to store a received message. Also, since the order is received from the start address, the farther from the start address, the more recently received message.

On the other hand, the display of each information (call message) can use a character as shown in FIG. 5 or an icon as shown in FIG. In the latter case, it is necessary to further have a memory area for storing icon data according to each type of information and a program for controlling the same. The icon screen shown in FIG. 6 is the simplest example and is a schematic representation of the type of information. When the user selects the desired information based on this icon, an icon screen for selecting a display form or amount of the information is displayed or the information is displayed immediately. The present invention as described above has the advantage that the user can quickly identify only the desired information by enabling the display by classifying the message received by the wireless call receiver by type. In addition, when a call message is received, the information classification to which the received call message belongs is determined and the corresponding icon is displayed along with the generation of an alarm sound, thereby making it easy for the called party to recognize the received fact. In addition, by displaying the number of homogeneous messages received up to that time together with the icon, there is an advantage of providing a higher quality service to the called party. Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the scope of the following claims, but also by the equivalents of the claims.
