Definitions

• the present invention relates to an arrangement in one or more communication networks, wherein communication channels are established between two or more parties connected to said communication network (s), said arrangement comprising communication services offering access to communication channels to interconnected parties .
• Communication services offer access to communication channels to interconnected parties. Interconnectivity is realised by communication networks. Examples of communication services are: voice communication services, video conference services, and file transfer services.
• PSTN Public Switched Telephone Network
• PS Land Mobile Network Public Land Mobile Network

• the present invention provides a system for automatic establishment of related communication channels with support for automatic correlation of the information sent on the established communication channels. More specifically, the present invention provides a system for automatic creation of a group of communication channels between two or more parties connected to communications networks. The creation of a group of communication channels is initiated by external events. An identical correlation key, which may be used to identify a group, is sent on each of the communication channels belonging to a particular group. The key facilitates automatic correlation of information sent on the related communication channels at the terminal equipment of the parties involved.
• the present invention provides automation of (1) and facilitates automation of (2), in a network centric fashion.
• CTI CTI combines computer technology and telephone technology.
• CTI may be used for call processing and for voice processing.
• CTI is used in Call Centre applications .
• CTI call processing enables a computer to work alongside a human agent, helping the agent to handle calls more efficiently (eg., route customer incoming calls to an appropriate operator based on information in a customer database) .
• CTI voice processing the computer takes the place of a human telephone operator and provides a gateway between the caller and the business information stored on the computer systems (eg., automated call answering) .
• a CTI system may automatically establish a telephony communication channel by initiating a call request to the telephone network.
• a CTI system may automatically correlate an incoming call (by extracting the Caller ID information element of signalling no. 7) with information stored in a customer database .
• CTI is very much dependant on the control functions provided to it by the telephone network. For instance, CTI relies heavily on the Caller ID information element of signalling system no. 7 to correlate incoming calls with information in customer databases. CTI cannot control the information sent from the telephone network, it can merely inspect it. Since it cannot control such information it is confined and limited by restrictions imposed by the telephone network.
• CTI is terminal centric in the sense that the logic and functionality is provided solely by additional terminal equipment (PABXs and computers) interacting with the telephone network. Automatic establishment of calls is initiated by additional terminal equipment requesting a service from the telephone network. CTI provides a means of adding value to the services offered by the telephone network. However, the revenue margins for this added value is out of reach for the traditional network operator since the means is provided by customer terminal CTI equipment - not by the network itself.
• WO 9638018 From WO 9638018 (LM Ericsson) there is know a method using an intelligent network that is invoked during call connection to provide connections and other information.
• the intelligent network can be connected to by ISDN or PSTN based telephones or via gateways to data networks, e.g. the Internet.
• the intention of this prior art is mobility within the data network in connection with conventional PST . services .
• the internet may be used in order to locate the user, which may be a mobile unit in the data network.
• the prior art is silent about any correlation between sessions and is also silent about using Internet for setting up sessions, and still more silent about transferring a correlation key for fascilitating such set- up.
• An object of the present invention is to provide a system for automatic establishment of related communication channels .
• Yet another object of the present invention is in connection with such an automatic correlation of sessions to use a correlation key for further optimizing said system.
• said arrangement further comprises control means for automatic establishment of related communication channels with support for automatic correlation of the information sent on said established communication channels.
• control means CU1 communicate with an external system (E) which in turn comprises event related data, which data can either be called upon by the control means (CUl) or be transferred thereto when certain events occur, so as to initiate the creation of one or more groups of communication channels, substantially on the basis of external events .

• the invention presents a solution that may be based on two logical interacting control units, Control Unit 1 (CUl) and Control Unit 2 (CU2) , respectively.
• the two control units with their interaction, form a system that enables automatic establishment of communication channels with support for automatic correlation of information sent on the communication channels at the terminal equipment of the parties involved.
• An example of communication channels that may have correlation support by the present invention is telephony calls and information stored on the Internet.
• CUl and CU2 are located within communications networks (eg. a PSTN or the Internet) and are capable of establishing communication channels (SI, S2 ) between two or more parties connected to the communication networks. CUl and CU2 may both act as parties in communication sessions. CUl and CU2 may be located within the same communications network or they may each be located within different communications networks. CUl and CU2 are logical units in the sense that their physical implementation may coexist, and coexist with other components. A communication path interconnects CUl and CU2.

• D must consist of control information that can be used by CUl, and may be used by CU2 , to establish sessions. D may also contain user information that may be transferred by CUl or CU2 , or both, to one or more parties involved in the channels to be established.
• CUl may request and initiate a transfer of input (D) from E or E may initiate a transfer of input (D) to CUl.
• Input (D) to CUl is initiated when certain events occure.
• Examples of events are: a date, the stock exchange reaches a certain threshold, a temperature measurement reaches a certain limit, an Internet user has filled in a registration form and inititated a transfer of information to a server (which may be E) , and so on. If CUl is used to initiate a transfer of input (D) , then CUl contains logic for the monitoring of events of interest that trigger a transfer of input (D) .

• the communication channels (SI) may be established based upon control information contained in D (e.g. the telephone numbers of two parties if these were contained in D, or the e-mail address of one party if this were contained in D) or it may be based upon information contained in CUl (e.g. a stored e-mail or FTP address) , or both.
• a communication session involves two or more parties (e.g. the placing and receiving parties in a traditional telephone call/session) .

Such forms are often found under the homepage of businesses offering transactions on the Internet. Once the Internet user has filled in the required form, the user often has to click on a web button to send the information off to the sales department of the business in question. The sales department may thereafter ship the requested product or service out to the customer based upon the information that the Internet user has specified.
• Products and services may be ordered using the PSTN.
• a typical procedure is the following: A PSTN user, and potential customer, initiates a phone call to the business of interest.
• the business may subscribe to certain IN services that route the call to, for instance, the sales department that is open for business at the particular time of day. Furthermore, that sales department may subscribe to certain IN services that enable the PSTN user to navigate his call to an applicable sales representative via a telephone menu.
