A wireless user terminal (10), such as a cellular telephone, includes a transceiver (14, 16) for conducting bidirectional RF communications with a communications network (32) and a data processor (18b) for controlling the operation of the terminal. The terminal further includes (a) a first memory capable of storing a data processor program; (b) a second memory capable of storing a data processor program; (c) a memory device or register for storing a flag for indicating which of the first and second memories is a currently Active memory, that stores a currently active data processor program, and which of the first and second memories is a currently Idle memory; and (d) circuitry for receiving another data processor program from the communications network and for storing the received another data processor program into the Idle memory. The circuitry operates while the data processor executes the data processor program stored in the Active memory.

Methods and apparatus for updating the software of a mobile terminal

A method for a cellular telephone automatic credit card calling system. In the analysis method, a series of program steps are provided for a digital signal processor (DSP) in the cellular telephone that activates the digital signal processor to listen to and analyze the received voice signals. The method may be considered as including three parts. (1) Tone detection method using the DSP to listen to the tone received from the calling card company. (2) Initializing the mobile phone for calling card use by selecting a default method on the ground of the telephone number of the calling card company. (3) Setting up a card call using the above mentioned tone detection (1), automatic insertion of '0' in front of the dialed number and call activation by a long press of the SEND-key. All of the three parts are manifested on the sequence of calling card process steps and implementation in the mobile telephone.
