Cordless telephone terminal
DC CAFCFirst Claim
1. A method for displaying data and processing appearances thereof from an alphanumeric display screen of a cordless handset in user-interactive radio communication with an associated base station of a cordless telephone terminal in onhook communication with a telephone exchange, wherein said base station comprises a memory device, and wherein said memory device comprises first and second submemories, said method comprising the steps of:
- generating predetermined command and alphanumeric data from selected ones of key operations at the handset;
enabling first processor means at the handset for displaying keyed alphanumeric data on the screen and concurrently transmitting the alphanumeric data and commands to the base station;
enabling second processor means at the base station for receiving the alphanumeric data and commands, retrievably storing the data in a first submemory of the base station and operably responding to the commands;
capturing service data from an incoming telephone call received at the base station;
testing the service data at the base station to confirm its validity;
retreivably storing the valid data in a second submemory of the base station and concurrently transmitting the valid data to the handset for display on the screen;
generating a set of user-interactive prompts having predetermined appearances on the display screen; and
accessing individual ones of the first and second submemories via key operations at the handset corresponding to the user-interactive prompts for selectively processing and editorially revising the alphanumeric data stored in the submemories while under display screen observation.

Abstract
An interactive cordless telephone handset having an alphanumeric data display system is in radio communication with an associated base station to which voice and data signals are conducted over a telephone line. Received caller identification data is tested for validity and is stored in a limited storage Callers List memory of the base station if found valid. Subsequently, the data is transmitted to the handset over a radio link of limited range, with the received data being formatted and conducted to a display screen for identifying the caller by name and telephone number prior to answering the call. Although caller identification is erased from the display after the call, it is retained in the Callers List memory of the base station where it may be accessed by the handset via softkeys and dedicated dialpad keys for subsequent display and editing and optional transfer to a general directory for long term storage in a nonvolatile memory of the base station.

17. A method for displaying data and processing appearances thereof from an alphanumeric display screen of a cordless handset in user-interactive radio communication with an associated base station of a cordless telephone terminal, comprising the steps of:
-
generating predetermined command and alphanumeric data from selected ones of key operations at the handset; enabling first processor means at the handset for receiving and operably responding to the handset data, displaying alphanumeric data on the screen and concurrently transmitting both command and alphanumeric data to the base station; enabling second processor means at the base station for receiving, retrievably storing and operably responding to the transmitted handset data; capturing digitally encoded calling line identification data from incoming telephone calls received at the base station, the station being onhook and the data including a caller'"'"'s name and directory number sequence; decoding and testing the captured data to confirm the validity thereof; retrievably writing the confirmed data to a callers list memory at the base station and concurrently transmitting the confirmed data to the handset for display on the screen; accessing a directory memory at the base station and selectively displaying the contents thereof on the handset screen; writing the confirmed data of the callers list memory to the accessed directory memory; substituting a personalized name input at the handset for a selected one of the names stored in the directory memory; comparing the directory number sequences of subsequent callers with the number sequences stored in the directory memory; and overwriting a subsequent caller'"'"'s identifying name stored in the callers list memory with the corresponding personalized name stored in the directory memory for each occurrence of coincidence between the caller'"'"'s identifying directory number sequence and the same caller'"'"'s number sequence stored in the directory memory.

19. A method for displaying data and processing appearances thereof from an alphanumeric display screen of a cordless handset in user-interactive radio communication with an associated base station of a cordless telephone terminal, comprising the steps of:
-
capturing digitally encoded calling line identification data from incoming telephone calls received at the base station, the station being onhook and the data including a caller'"'"'s name and directory number sequence; decoding and testing the captured data to confirm the validity thereof; retrievably writing the confirmed data to a callers list memory at the base station and concurrently transmitting the confirmed data to the handset for display on the screen; writing the confirmed data of the callers list memory to a directory memory at the base station; substituting a personalized name input at the handset for a selected one of the names stored in the directory memory; comparing the directory number sequences of subsequent callers with the number sequences stored in the directory memory; and overwriting a subsequent caller'"'"'s identifying name stored in the callers list memory with the corresponding personalized name stored in the directory memory for each occurrence of coincidence between the caller'"'"'s identifying directory number sequence and the same caller'"'"'s number sequence stored in the directory memory.
