Abstract:
A system (2) uses conventional text messaging capabilities of cellular telephone systems to embed one or more call-back telephone numbers. A start delimiter (204) is used to separate a text data portion corresponding to the call-back telephone number (208) from the text message (214). A termination delimiter (210) may be used to indicate the end of the text data portion corresponding to the call-back telephone number (208). Multiple text data portions, corresponding to multiple call-back telephone numbers, may be inserted using multiple start delimiters and termination delimiters. A text parser in the cellular telephone searches the text message for the start delimiter and extracts the text data portion corresponding to the call-back telephone number. The cellular telephone user selects a desired call-back telephone number, which may be placed in a dialing queue for simplified communications between the cellular telephone and a destination corresponding to the selected call-back telephone number.
Abstract:
A cellular radiotelephone (100) which uses voice feedback to announce which key of the keypad (155) has been depressed or to indicate the status of radiotelephone (100). The voice signals for the feedback are stored in memory (150) in a digitized and compressed format. The radiotelephone's speech CODEC (140) decompresses the appropriate digital signal. The CODEC (140) transforms the digital signal to an analog voice signal for use by the radiotelephone's audio output device.
Abstract:
A system for user-programming of system parameters of a cellular telephone (100). Data values for the system parameters are stored in a nonvolatile memory (112) within the cellular telephone. A password storage area (116) stores one or more predetermined passwords. After purchasing the telephone (100), the end-user calls a predetermined telephone number and receives one of the predetermined passwords. The user enables a programming mode and enters the predetermined password using the cellular telephone keypad (20). If the user-entered password matches the stored predetermined password, the cellular telephone (100) allows user access to at least a portion of the system parameters in the nonvolatile memory (112). A counter (120) tracks the number of user-programming attempts and terminates the programming after either a predetermined number of failures or successful programming of all the desired system parameter values.
