For various reasons, many people do not answer, when they receive unidentified calls. This is a problem for people who initiate these calls, especially for business reasons. Up to now, there is a supplementary service CNIP (Calling Name Identification Presentation) which provides the number of the calling user (A-party) to the called user (B-party). This is a B-side service offered to the called user. This solution works unless the CLIR (Calling Line Identification Restriction) service is set on the calling party name. It is proposed to implement an A-side feature which allows the calling person to keep its number private and allows at the same time the called party to have a part of calling person's identity. Depending on the type of the subscriber and the information that he wishes to make public, there are two embodiments of the proposed idea. The first embodiment concerns business subscribers e.g. companies and organizations. This embodiment allows to send information relating to the brand name of the company to the B-party and at the same time to keep the Directory Number (DN) secret. Technically, it is realized as follows: According to ETS 300-659-1&2&3 Data Transmission can be associated with ringing and can take place during ringing. The Data Link message "Call Set-up" can be used to send information related to the incoming call. The "Call Set-up" message may contain different parameters. The information about the company can be sent with the Calling Party Name parameter. It is advantageous that this parameter can represent up to 50 characters. In ISDN, the Calling Party Name is transported with the Display IE (Display Information Element) in the message "Call Set-up" and takes place as CLIP (Calling Line Identity Presentation). In analogue technique, the Calling Party name can be transported with FSK (Frequency Shift Keying). The Calling Party Identification can be either listed as an alphanumeric code in a database of the originating node or in a centralized IN (Intelligent Network) database in a Service Control Point.
