Abstract
Abstract A radiotelephone (RT) operates in either a cellular telephone mode or a cordless telephone mode within a cellular telecommunications system. The RT operates in the cordless mode if it is within the operating range of a cordless base station. The cordless base station receives data from a central telephone office, converts the data into a transmittable caller ID message, and transmits the caller ID message to the RT. The RT receives the caller ID message and displays it in a readable form to the user. The caller ID message may be saved at the RT for subsequent retrieval by the user. In addition, a speed dial operation may be performed to respond to the caller ID message.
