Radio paging receiver capable of receiving facsimile data and method for controlling the same

In a radio paging system having a base station connected to a Public Switching Telephone Network (PSTN), and a plurality of radio paging receivers, said base station broadcasting a signal which is received by the radio paging receivers, said signal being broken down into sections and having address fields for addressing particular sections to individual radio paging receivers, a hand-held radio paging receiver capable of receiving facsimile data, comprising:

• a code detector for detecting a coded signal received from an antenna, said coded signal includes a synchronization signal, block information, fields for addresses and vectors, messages, and said facsimile data, said vector field for determining the type and beginning position of a particular section addressed to an individual radio paging receiver;
• means for converting said facsimile data to image data;
• a display for displaying the image data;
• a key input device including an up-key, a left-key, and a right-key for scrolling the image data displayed on the display;
• a plurality of line pointers for pointing to a beginning of a line to divide the image data;
• first and second output pointers for pointing to an output position of image data, said first output pointer pointing to a location in said memory of the uppermost and leftmost position of the portion of the image data on the display, said second output pointer pointing to a location in memory of the lowest and rightmost position of the portion of the image data on the display;
• and
• a controller for processing the coded signal and the image data and for calculating a moving position of first and second output pointers in response to a key input from said key input device, and reading the image data pointed by said first and second output pointers to display the read image data on the display.

In a radio paging system having a base station connected to a Public Switching Telephone Network (PSTN), and a plurality of radio paging receivers, said base station broadcasting a signal which is received by the radio paging receivers, said signal being broken down into sections, said sections containing information addressed to individual radio paging receivers, a method for receiving facsimile data via a radio paging receiver including a memory for storing received image data by a line unit, a key input device for generating position movement key data, and a display for displaying the image data, comprising the steps of:

• i) checking whether or not the position movement key data is received;
• ii) checking whether or not the image data displayed on the display is a first line, in response to an up-key data input;
• iii) checking whether or not the image data displayed on the display is a last line, in response to a down-key data input;
• iv) checking whether or not the image data displayed on the display is a leftmost end of a line, in response to a left-key data input;
• v) checking whether or not the image data displayed on the display is a rightmost end of a line, in response to a right-key data input;
• and
• vi) calculating a data output position according to the checking results and the position movement key data of said second through fifth steps, and reading the image data at the calculated position of the memory to display the read image data on a display.
