Abstract
A communication system and in particular a paging system for transmitting information includes a keyboard, an encoder, a transmitter, a paging, the paging receiver comprising, a decoder, a microprocessor, and a display. Entered information includes a plurality of languages and a corresponding language select signal, each language comprised of a plurality of characters. To increase throughput, the language characters are compressed by the encoder to a common set of characters. The information including the languages is transmitted to a plurality of selectable paging receivers. The paging receiver decodes the information and converts the transmitted received characters to corresponding language symbols according to the transmitted received language select signal. The language symbols are then displayed on the display.

9. A method for transmitting information including a plurality of languages to a paging receiver in a paging system, the paging system including an input means, an encoder, and a transmitter, said method comprising the steps of:
-
(a) entering the information with the input means, the information including at least one data message having a plurality of languages, a language being comprised of a plurality of symbols and a corresponding control signal representative of the language of the symbols; (b) converting each symbol of the language into a corresponding character of a set of common characters; (c) coding the common set of characters and control signal into a message format adapted for transmitting information to a plurality of paging receivers; (d) transmitting the information to at least one of a plurality of paging receivers; (e) decoding the information at the paging receiver for providing a plurality of symbol signals and a recovered control signal wherein each symbol signal corresponds to a transmitted language symbol and said recovered control signal represents the language of the symbol signals; (f) choosing a predetermined set of symbols in accordance with the recovered control signal; (g) adding a predetermined value to the symbol signal corresponding to the recovered control signal; (h) selecting from the predetermined set of symbols, a symbol corresponding to the symbol signal; (i) converting each of the symbol signals to a symbol corresponding to the recovered control signal; and (j) displaying the symbol for producing a display of the symbols. - View Dependent Claims (10, 11)

12. A method for displaying a plurality of symbols in a paging receiver having a memory comprised of at least two symbol areas, each area being representative of a language and associated with an operating mode of the receiver, one of the symbols areas being a base language symbol area and the other symbol area being an alternate language symbol area, and further wherein each symbol area is comprised of a plurality of characters, wherein each character is representative of a displayable symbol, said method comprising the steps of:
-
(a) providing a control signal as part of one or more data messages transmitted to the paging receiver, wherein each data message includes the base language and the alternate language, each language being a plurality of symbol signals and further wherein the control signal represents the language of the characters associated with the receiver, each of said data messages comprising one or more characters in the language designated by said control signal; (b) choosing the alternate language symbol area in response to the control signal; (c) choosing the base language symbol area in response to the absence of the control signal; (d) selecting a character from the chosen symbol area corresponding to the symbol signal; and (e) displaying a symbol corresponding to the selected character for creating a text display of the symbol signals in the paging receiver. - View Dependent Claims (13, 14, 15)
