Technical field

The invention relates to an intelligent network, IN (at least one Intelligent Network) comprising at least one service switch point, SSP (at a Service Switching Point), at least one service control point, a SCP (at a Service Control Point), one or more Intelligent Networks. peripherals, IP (Intelligent Peripherals), and (or) one or more Voice Response System (VRS) in which IN is capable of interacting with a Public Switched Telephone Network, PSTN (Public Switched Telephone) Network) or Integrated Services Digital Network (ISDN).

BACKGROUND OF THE INVENTION

Currently, IN standards (AIN 0.1, AIN 0.2, CS1 and CS2) are used for IP playback, VRS reporting, and DTMF (Dual Tone Multlple-Frequency). In today's modern IP and VRS applications, however, there is more to the function than just playing simple messages and receiving DTMF tones. If these more complex functions are to be used, this will in most cases mean that the IP will also collect more complex PSTN call information. For many services, it is important to switch to the next destination based on the information collected after receiving the information. However, since the IP cannot provide feedback to the SCP, the call will still be controlled by the IP, which will interpret it if necessary. As a result, all routing must always be routed via IP (or VRS). Lines available on IP (and VRS) are busy for a longer period of time, which is the main reason for the need for modern IP and VRS applications.

SUMMARY OF THE INVENTION

It is an object of the invention to ensure that, in contrast to the aforementioned prior art, IP and VRS supply the collected information back to the SCP. The IP or VRS can then forward calls to the service connection point (SSP) so that the line on the IP or VRS is cleared. Based on the received information, the SCP may instruct the SSP to switch calls to another destination. In order to achieve the intended purpose, the sff according to the invention functions in accordance with the present invention. as a Pidlcf Clen that is connected to IP and / or VRS outputs on the one hand to record information signals emitted by said IP or VRS that you come from! calls from PSTNs offered by said IP and / or VRS via SSP. This driver aligns signals recorded from IP and VRS, while on the other hand, the driver is connected to the SCP to output information signals to the SCP instead of IP and VRS.

By using a control element according to the invention, several IP or VRS modules can be easily connected during a call without the need for a special IP-IP interface. If the concept according to the invention is used, the IP or VRS will be occupied only for the minimum time period required. Because in this concept SSP always activates IPs or modules, no interfaces between modules are required. Modules can be easily combined during the service. Thus, for example, it is easy to integrate a new credit card verification module into existing services by including module calls. If modules are already in use, any desired combination with these modules is possible without the need to adapt the interface of existing modules.

Because the SSP constantly sets new outgoing calls while browsing different modules, it is possible to specify a different rate for each module. In this case, the speed can be stabilized by a conventional SSP speed fixation process. If the concept of the invention is not used, the switching needs to perform IP, since only one rate will be allowed for the entire call for rate fixation in the SSP.

By placing a central control member on the connection between IP and VRS, a central point of interface is created, with which not only the SCP can be controlled, but also information from external databases can also be written or retrieved. This connection is especially important when telephone services are combined with data services (also called Computer Telephony Integration, CTI), an example of which is the synchronization of the sorting of data coming to

-3operators and containing the data of the Client and the incoming calls from the clients to the specified operators.

The concept is not very flexible, because it is possible to choose different IP (VRS) for each module. The combination of modules is done from SCP and SSP switching. As a result, all modules can be combined in any order. If modules are added (with additional options), they can be combined with all existing modules during service. I recommend reports that follow.

DETAILED DESCRIPTION OF THE INVENTION

The figure shows the structure of Super * IP * according to the invention. The figure shows PSTWSDN1 and, as part of the Intelligent Sector architecture, SSP 2 to which VRS and IP 5 are connected. The SSP is longer connected to the SCP. According to the invention, a control member 6 is provided which forms a buffer and a link between IP and VRS and SCP, thereby allowing the SCP to drive advanced control signals from modern IP and VRS, but without the (costly) beers. These will only be used when necessary; the output of said elements will be contained and equalized in the control member 6 until the SCP is able to utilize the equalized Information. Therefore, the binding (shown in bold in the figure) can be used to exchange data collected for a call. The IP, VRS, or control may also provide instructions, even through binding, to the SCP to further process the call. When the binding takes place through a central control member, a central junction point is created which can also be used as a bridge to the world of information technology, such as external information technology systems and / or databases that represent sff 2, eg the Internet. TCP / IP (Transmission Control Protocol) is used between IP and VRS and the controller, and is also used for Internet 7 communication. In connection between controller 6 and SCP, the protocol is used. INAP (?).

The central driver member 6 may also utilize IP and VRS information to control connections in computer telephony (CTI) integration towards desired destination destinations (delimited by the control member and forwarded to the SCP). An example is the transmission of operative sorted data with client information (based on the received signaling information, such as the telephone number of the caller) to

-4 * · · ·· the final destination (operator), which also synchronously receives calls from the client. According to this idea, the central control member acts as a synchronization point for telephone and data services. Thus, according to this concept, the SCP and the SSP carry out a possible call transfer, so the network automatic call distribution, ACD (Automatic Call Distribution) and CTI solutions are also automatically offered.

The major advantages of applying the inventive concept are:

Shorter IP and VRS line capacity because IP or VRS may not only switch, but can also forward control and calls to SCP and SSP. IP and VRS are divided into Call Parts, so IP and / or VRS can be easily addressed within one call. In addition, IPA / RS can be combined easily and flexibly within a single service.

- The concept can be easily expanded by using other new IP and / or VRS modules as modules. In applying the concept, interface problems between IP and / or VRS are minimized.

- Because separate sub-calls are set for each module, a different rate can be used for each module.

- Using a central control member allows synchronization of telephone and data services.

- Because call switching is still controlled by SCP (and not IP, VRS, or PABXS - from Prlvate Automatic Branch eXchange), ACD and CTI solutions can be easily implemented across the network.
