Abstract

The invention relates to a method for processing information in a wireless local loop (WLL) terminal and a WLL terminal. According to the present invention, a WLL terminal comprises a display device, and character-based information, first data, is converted to second data for displaying it on the display. Said first data is advantageously converted in such a manner that a bitmap (222) is first formed on the basis of the character-based first data and then a line code (223) is formed on the basis of said bitmap. The line code is transferred (224, 225) by means of known facsimile transmission technology to a fax machine serving as a display device and displayed by the fax machine (226). The invention can be applied in wireless local loops to implement services that use information in character format. Such services include the short message service and display of caller data.

Claims

1. A method for processing information in a WLL (wireless local loop) terminal, comprising the steps of:

storing said information in the WLL terminal as character-based first data,

converting said information stored as character-based first data to second data comprising facsimile readable line code to be displayed as a facsimile presentation on a displaying means, and

displaying said information on said displaying means as a facsimile presentation.

2. The method of claim 1, further comprising a step of receiving said information in the WLL terminal from a WLL system.

3. The method of claim 1, wherein, in said step of converting said first data to the second data, there is a step of forming a bitmap on the basis of the character-based first data and then a further step of forming the line code on the basis of said bitmap.

4. The method of claim 3, wherein said converting is performed one displayed character line at a time.

5. The method of claim 1, wherein said second data comprises line codes that include a start character, at least one character representing the lengths of black/white pixel sequences, and an end character.

6. The method of claim 1, wherein said second data is coded to a voice-frequency signal to be transferred to said displaying means.

7. The use of the method of claim 1, for displaying short messages, incoming call phones number information or system status information.

16. The WLL terminal of claim 7, for displaying short messages, incoming call phone number information or system status information.

8. A WLL (wireless local loop) terminal, comprising means for storing information as character-based first data, displaying means for displaying said information, and means for converting said first data to second data having the form of facsimile readable line code to be displayed as a facsimile presentation by said displaying means.

9. WLL terminal of claim 8, wherein said converting means includes means for converting said information to third data for transferring said information to said displaying means.

10. The WLL terminal of claim 8, wherein said displaying means is a fax machine.

11. The WLL terminal of claim 9, further comprising means for establishing a connection and for transferring said information to said fax LAB machine as a voice-frequency signal.

12. The WLL terminal of claim 8, wherein said converting means includes means for converting the first data to a bitmap.

13. The WLL terminal of claim 12, wherein said converting means includes means for converting said bitmap to second data in the line code format.

14. The WLL terminal of claim 8, wherein said displaying means is an integral part of said WLL terminal.

15. The WLL terminal of claim 8, further comprising means for receiving said information from a WLL system base station.
