  • Patent number: 5995824
    Abstract: A telecommunications system and method for providing cellular phone voice recording to subscribers, in order to simplify the recording of information while using a mobile terminal, and to increase the safety of the subscriber while operating a motor vehicle. For example, during a call, a subscriber may initiate the recording feature by pressing a dedicated key or a sequence of keys on the cellular phone. This feature can be implemented completely within the cellular phone itself, or it can be implemented in the Mobile Services Center/Visitor Location Register (MSC/VLR). With this feature, a subscriber can record information at any time during a call without the need for recording materials, e.g., paper or the scratch pad function on the cellular phone, which both increases the safety of the subscriber while driving, and provides a convenient manner of recording information.
