Abstract
According to the inventive method, call back information is transmitted to a telephone network via an internet terminal using a click-to-dial service. In order to verify the information, the telephone network extracts internet terminal specific information from the access server via the internet. After comparing the call number information which is contained in the call back information and in the internet terminal specific information, the return call is initiated or suppressed. Return calls to subscribers who do not want to be called are thus suppressed.
Claims8
A method for verification of callback information (rri), by means of which a PSTN return call by an Internet service provider is initiated by an Internet terminal (PC(TLN)), with the Internet connection being controlled by an access server (ZS), characterized
- in that the currently associated IP address (ipa) of the respective Internet terminal (PC((TLN)) is recorded in the server of the service provider (SER(DA)), and the access server (ZS) is identified on the basis of the IP address,
- in that the server of the service provider (SER(DA)) transmits an Internet-terminal-specific request (ai) to the access server (ZS),
- in that Internet-terminal-specific information (iter(ni,rni, . . . )) is determined in the access server (ZS) and is transmitted to the requesting server of the service provider (SER(DA)),
- in that the information transmitted by the access server (ZS) is used to verify the callback information (rri), and
- in that a return call is initiated or is prevented as a function of the verification result.
A method for verification of callback information (rri), by means of which a PSTN return call by an Internet service provider is initiated by an Internet terminal (PC(TLN)), with the Internet connection being controlled by an access server (ZS), which is connected to a communications system (KS), which provides the switching functions for setting up and making PSTN return calls, characterized
- in that the currently associated IP address (ipa) of the respective Internet terminal (PC(TLN)) is recorded in the server of the service provider (SER(DA)),
- in that the server of the service provider (SER(DA)),passes the IP address (ipa) to the communications system (KS), where the access server (ZS) is identified on the basis of the IP address (ipa),
- in that the communications system (KS) of the service provider transmits an Internet-terminal-specific request (ai) to the access server (ZS),
- in that Internet-terminal-specific information (iter(ni,rni, . . . )) is determined in the access server (ZS) and is transmitted to the requesting communications system (KS),
- in that the information transmitted by the access server (ZS) is used to verify the callback information (rri), and
- in that a return call is initiated or is prevented as a function of the verification result.
The method as claimed in one of the preceding claims, characterized
- in that the Internet-terminal-specific information (iter(ni,rni . . . )) which is emitted by the access server (ZS) for registration of the Internet terminal PC(TLN) is stored in an additional server DB(LDAP, (ni,rni, . . . )) and is read by means of an LDAP protocol, and
- in that this additional server DB(LDAP, (ni,rni, . . . )) is accessed directly with the aid of the LDAP protocol by the server of the service provider SER(DA) or by the communications system (KS), and the Internet-terminal-specific information (iter(ni,rni, . . . )) is requested and transmitted.
