Communication connection establishment control for preventing unsolicitated communication

Abstract

There is proposed a mechanism for controlling a communication connection establishment to a subscriber using service comprising blacklisting, whitelisting, authentication request and / or Turing test for unsolicited communications prevention. Furthermore, there is proposed a management system used to configure a corresponding communication connection establishment control on the basis of an interface for the subscriber for defining a personalized communication connection establishment control profile.

Description

technical field [0001] The invention relates to a mechanism for controlling the establishment of a communication connection to a subscriber and to a management system for configuring the corresponding communication connection establishment control. In particular, the present invention relates to communication connection establishment controls providing protection against unsolicited communication (UC), such as Internet SPAM technology (SPAM over Internet Telephony, SPIT), and to a method for configuring the corresponding control management system. Background technique [0002] In recent years, for example, wired communication networks (such as Integrated Services Digital Network (ISDN) and Digital Subscriber Line (DSL) access to the Internet) or wireless communication networks (such as cdma2000 (Code Division Multiple Access) systems, similar Cellular third-generation (3G) communication networks based on Universal Mobile Telecommunications System (UMTS), cellular second-gen...

AI Technical Summary

Problems solved by technology

[0016] The disadvantage of the first two responses (legislation, regulatory authorities) is that responses are complex and slow

The third countermeasure (contractual conditions of the operator) may be effective, but it is difficult for the operator to prove the abuse of its contractual conditions

[0018] However, even if these technical approaches can provide countermeasures against SPIT / UC, certain problems remain

For example, these systems only deal with SPIT / UC prevention in VoIP networks, so that users of other networks (such as traditional networks) who are potentially also compromised by SPIT / UC originating from VoIP cannot be protected thereby

Furthermore, these approaches require changes in SIP signaling and possibly VoIP network interface definitions that convey SPIT / UC related signaling data, making their implementation difficult

It must also be considered that besides technical and architectural issues, there are also legal aspects affected by these approaches, such as privacy protection (whether an operator is willing or allowed to indicate to another operator that a particular user is considered a SPIT / UC source) or liability issues (possible legal ramifications if operator B blocks important calls based on operator A's erroneous SPIT / UC decision)
