Abstract: PURPOSE: A method for originating urgent call in a terminal is provided to use a specific key set up as an abbreviated dial and to use an urgent call originating key, to perform a call connecting process when a user is in an emergency or needs help, so as to quickly notify a present situation of the user. CONSTITUTION: A user presses a specific key set up for an urgent call origination for seconds(S31). If a terminal senses the specific key inputting, the terminal originates a call to other base station corresponding to an urgent phone number prestored by the user(S32). The terminal decides whether the other base station senses the originated call(S33). If a call connection fails, the terminal automatically reattempts the call connection, by considering the time when a continuous call attempt is requested according to variable situations of the user(S34). If the call connection is successful, the user starts originating a prestored speech over one time, by using a voice or a message(S35). The speech is prestored for the time when the user is in the various situations. The terminal decides whether the originating is completed(S36). If so, the terminal decides whether an 'end' key is pressed in a key input circuit, to decide whether the call connection has to be completed or maintained(S37). If the user does not press the 'end' key, the terminal maintains the call connection(S38). If the 'end' key is pressed, the terminal completes the call connection and returns to a general call standby state(S39).

Abstract: PURPOSE: A data deinterleaver and a method for generating an address are provided so that a production cost can be reduced by decreasing a number of gate devices. CONSTITUTION: A memory stores interleaved data. A row counter counts system clocks by an interleaver depth. Whenever the row counter finishes one-cycle counting, a plurality of counters increase counting, thus repeating a series of cyclic counting operations. A multiplexer sequentially selectively outputs the output from the column counters according to the row counter value input. An operation unit multiplies the output from the multiplexer by the interleaver depth, adds the row counter value to the resultant value, and generates a memory address. In addition, in a method for generating an address for accessing a memory storing interleaved data, system clocks are repeatedly counted by an interleaver depth, and a row counter value is generated. Thereafter, when one cycle counting of a row address is finished, the counting is increased to repeat a series of cyclic counting operations, and column counter values are generated by the interleaver depth. The column counter values are sequentially selected according to the row counter value output. The selected value is multiplied by the interleaver depth, the resultant value is added to the row counter value, to generate a memory address.
