Description

METHOD AND SYSTEM FOR PLACING A CONVERSATION CONNECTION IN DIFFERENT NETWORKS The invention relates in general to the collation of a conversation connection and especially to a system comprising an intelligent network and a data network with connected computers.

The rapid growth of telecommunication means that telemarketers can offer their users many different types of services. An architecture of r »d qu» offers advanced services is called the intelligent r ° d IN. The architecture of the network can be applied in most telecommunication networks, for example, in telephone networks PSNT (Public Switched Telephone Network) as well as in r ^ d ^ s - ISDN - and B-ISDN (Digital Network Services two-bandwidth - ISDN.) Regardless of the technology of the network, the purpose of the architecture of the intelligent network is to facilitate the creation, control and management of new services of telecommunication.

The Service Switching Point (SSP) contains the functions of call handling and service selection. You can observe the requirements of the service ^ the intelligent network. The Service Control Point (SCP) contains the service programs used to produce < -ir the services of the intelligent network. The Service Data Point (SDP) is a database that contains the client and the network data that the SCP service programs use to produce individual services. LT Intelligent Periphery (IP) offers special functions, such as message and voice identification and multiple dialing. The task of the Service Management Point (SFM) includes the management of the database, the control and checks of the network, as well as the data collection of the r «d. It can be connected to all other physical entities.

The Basic Call State Model (BCSM) that is defined in connection with the IN network illustrates the different stages d < = l control of the calls and contains the points where the control of the calls can be interrupted in order to start the service of the intelligent network. This identifies the detection points in the call and the connection process, where the entities of the IN service logic can be in interaction with the basic call and the characteristics of the connection handling.

As previously mentioned, the architecture of the intelligent network can also be applied to the ISDN network. The Integrated Digital Services Network (ISDN) is characterized in that the user can use the same user interface with communication services, either separately or simultaneously. Different applications, such as, for example, the terminal, the terminal group, multiple service exchange, local area network, another private network, etc., are connected to the ISDN by a user-restricted interface group. The ISDN network is provided for the development of the present telephone to be part of a multi-service terminal, such as the combination of "telephone + PC", allowing simultaneous transmission of the conversation and information.

The interface of the ISDN user network provides different 'channel types' is for the transmission of information between the subscriber and the network. The B-channel that operates < at a speed of 64 kbit / s and provided with synchronization, it is used for all information transmissions, for example, for the transmission of all types of information or coded conversation. The D-channel, whose transmission speed can be 16 kbit / s or 64 kbit / s, it functions mainly as a signaling channel for circuit switched connections.

"The combination of the channels provides the constructions, ^ 'different channel and the interfaces of the user-ISDN.

, ^ Basic Access has a 2B + D structure and the Access of the Basic System has a structure 30B + D. Basic Access is used to connect one or several terminals The known services of the intelligent network are remote control calls, the deviation of follow me (FDM) where the subscriber to the service receives a number in which the incoming calls are transferred according to the telephone number each time the subscriber registers it, and the personal number UPT (telecommunications of the universal personnel ) where the subscriber to the service can make calls from any terminal and receive calls from any terminal in different networks. In this last service, the so-called type is only restricted by the properties of the terminal and the network; the subscriber has an independent network and personal number.

The problem with the types of services described above is that calls can not be transferred to a telephone connected to a network formed by computers, data networks, which are outside the digital network, for example, the ISDN network. In this network, the transmission connections can, for example, be based on the ATM. The global Internet is an example of this network. In the network of 'data, each terminal as the PC or work station, has its own data network address to receive the arrival information. On the Internet, the standard address has the form of user @ fuern. ,, fueral. O.cima. The user is the user's name, the ou can be from zero to several and top is the top-level domain; in Finland, for example, fi. If a telephone is integrated into a terminal like this, a mechanism has not yet been introduced to establish a call between this telephone and, for example, a subscriber connected to the ISDN network. The lack of this mechanism prevents the use of intelligent network services, such as the UPT personal number: The objective of this invention is therefore to provide a mechanism with which the subscriber can first call any number from a telephone connected to the data network, such as an internet via the work station, and second, that the Subscriber can direct incoming calls to the workstation that is currently in use. In the latter case, the calling party does not necessarily need to know the location of the called party.

The stated objective is achieved by the method presented in claims 1 and 14, and the system is incorporated by the measures according to claims 17 and 18.

The invention is a method for placing a conversation connection between users of two or more terminals that are in different networks in a system comprising an intelligent network, in which the call from the exchange and / or switch is transferred through of the Service Switching Point (SSP) that gives rise to the investigation via the common channel of the signaling network towards the service database, where the required information is located for the handling of the call and which returns this information through the signaling or corresponding signaling network and the SSP back to the exchange and / or switch; a data network where at least one registered computer has an address of the data network and a telephone integrated to the computer, and an access that connects the networks; in this method the address information of the computer that gives input to the communication in the data network is transferred to the access; from the access the message is transmitted to the intelligent network to update the data of the address of the subscriber's computer registered in the data network, and the connection of the conversation between the mentioned subscriber and the other subscriber controlled by means of the smart network when the connection of the conversation is desired.

The invention uses the intelligent network and the personal addresses of the work stations of the data network, so that when the subscriber starts his work station and connects to the data network, at the same time he sends his current address to the data network, as well as its personal identifier Pl, which are transmitted to the access that connects the data network and the ISND network: The Internet is used as an example in the description.

Access converts the Internet address to an ISDN address and sends this address and identifier Pl via the Service Switching Point (SSP) of the intelligent network to the Service Control Point (SCP). The SCP stores the data in the database for data from the Service Data Point (SDP).

All the control functions are concentrated in the intelligent network, with which a conversation connection can be established between the subscriber and any other subscriber that uses the functions of the intelligent network. The other subscriber can be an ISDN subscriber, a PSTN subscriber or a subscriber connected to the data network. Because the intelligent network has a route information of the subscriber's location, the subscriber can use the services such as the FMD remote control call (deviation follow me) and the personal UPT number (universal personnel telecommunications).

The invention is presented in more detail below by way of a preferred form of mode and with reference to accompanying photographs, in which: Figure 1 presents the architecture of the system in a simplified form.

Figure 2 shows a simplified access construction.

Figure 3 shows a basic diagram of how calls can be placed on the network after registering the workstation on the user's phone.

Figure 4 presents a block diagram of the activation of call control in the IN.

Figure 5 shows a block diagram of the data steps recorded at the workstation towards access.

Figure 5 shows a diagram of another possible activation of the Figure.

Figure 1 presents with the reference number 1, all • the essential functions of the IN network for the subject invention. The general tasks of the service switching point 13 and the service data point 11 were already presented at the beginning of the description. The intelligent network 1 is switched to the ISDN network 2 through the service switching point 13. The reference number 6 presents the subscriber's device, in this case it is a telephone that is switched with the Basic Access 2B + D construction directly with the ISDN network. The interconnection of the ISDN network 1 and the intelligent network 2 is well known in the field.

The reference number illustrates the network formed by computers, which here is an internet that has workstations or PC 5. Network 3 is also known as such. The PC includes a central processing unit (CPU), memories (program and main memory, such as ROM or RAM, (hard drive), letters to produce additional activities and a communication transfer path to connect the parties. The input and output of the PC can be displayed on the screen, or for example they are a printer. The user can enter data using the corresponding keyboard, mouse or other standard power supply device. The PC contains current multiple information equipment for photo, voice or text processing. The PC is provided, for example, with a sound card or the corresponding microphone and speaker that can be connected for transmission and reception of the conversation. The microphone and the speaker can be built into the device of the PC or peripheral of the PC, the display unit, be external or a common microphone. For the data network, the PC is provided with a network adapter through which the PC is in connection with the data network.

For the interconnection of networks 2 and 3, the ISDN 4 access is suggested below; the simplified block diagram, which is presented in Figure 2. Access 4, which can be a server, comprises a user interface to the ATM network, which includes the "hardware" 42, its "drlvers" 44 and the block of the internet protocol processing 45. On the other side it comprises a user interface to the ISDN network, which can be a standard basic system access 30B + D, including the hardware 41, its drivers 43 and the program of development sets of the drivers 46.

According to the invention, the attachments of the access function are as follows: access 4 speaks with the computers connected to the computer or the data network, and counts at least with the following tasks: a) call identification, it is say, identify the request for the call from the ISDN and the data networks; b) the transmission of the numbers A- and B-, and s) the creation and release of the connection of the conversation within the access and from the access to the telephone of the work station. The access switching control program 48 receives the internet address from the ATM network and converts it into a decimal encoded ISDN address. Transmits the converted address to the intelligent network so that it is registered in the database of the SDP user. In the method according to the invention, the routine information to the user has to be transmitted to the intelligent network database. This happens so that the user registers normally on the internet when the workstation starts, possibly using a password. From there, the user registers within the intelligent network by starting a special telephone program. The program sends to the access an internet address in accordance with the internet protocol (IP) and the personal identification number of the user given to the workstation by the user in response to the request of the telephone program. The service number of the intelligent network that handles call control can be automatically added to the transmission by the program or should be added by the user. The service can be of the known personal number type UPT (universal personnel telecommunications). The set of information sent by the program to access is therefore "the service number of the intelligent network + the IP address + the personal identifier of the user". The mechanism to form and transmit this set of information in practice is not essential for the invention; what is really essential is that the access receives the information set.

When the access receives information from the data network of the information set sent by the workstation, its switching control program 48, FIG. 2, encodes the IP protocol address to the decimal form used in the ISDN world. The form of the internet address is called the dotted decimal representation of the binary bit information structure 32, by which the address can be expressed in the form of 8bit. 8bit. 8bit. 8bit. The binary address is encoded in decimals within * of the digit decimals 10 (10 base figures) in a known way. Access 4 transmits the series "intelligent network service number + decimal encoded IP address + user's personal identifier + access address" to the exchange of the ISDN network, using, for example, the AX exchange of Telefonaktiebolaget LM Ericsson and ISDN connected to it * The access can use an appropriate message for the transmission of these series in accordance with the ISUP protocol (User Part of the Digital Services Network (CCITT Number 7) (International Telephone and Telegraph Consultative Committee), such as the IAM message (Initial Address Message) and place the data in a suitable field of IAM message defined in ETSI (Institute of European Telecommunications Standards). An appropriate field could be the known subfield of the number A- or B- or directly the field of the number A. In both cases, the intelligent network is able to read the transmitted information.When the message reaches the exchange, the service switching point of the intelligent network SSP 13, figure 1, identifies the service number of the intelligent network and the intelligent network service begins The service places the decimal address of the encoded IP defining the subscriber's location + the user's personal identifier + the address of access in the database of service data. When the subscriber making the call, for example the subscriber ISDN 6 dials the service number of the intelligent network and the personal identification number of the registered subscriber within the intelligent network through the workstation, the intelligent network is capable to extract the information from the database of the calling subscriber and consequently connect the call to the integrated telephone to the computer. All calls to and from the workstation are centralized, controlled by the intelligent network. Thus, the route of the call is using standard IN databases and nodal route tables of the traditional ISDN network. The call is routed to an access obtained from the subscriber data, whereby the access performs the conversion of the IP number and from there routes the call to the correct workstation.

In accordance with a preferred embodiment, the intelligent network service is like a personal number UPT service, which is here referred to as the advanced personal telecommunication service. The advanced personal telecommunication service allows you to find the person from several numbers. The subscriber to the service has a personal number that includes the number of the intelligent network service + the personal subscriber's identifier. The number could be, for example, 02-08-445566. The number 02 defines the operator and the number 08 to the operator's service, which is an advanced personal telecommunication service in our example. In this way, from the point of view of the subscriber, 0208 is a service number. The number 445566 is the identifier of the user.- »personal. The mobile telephone number of the subscriber, the number of the warning device, the voice mail number and in accordance with the subject invention, the telephone number of the work station was registered in the intelligent network. The subscriber making the call only dials the number 02-08-445566, which transfers the call to the intelligent network, whose intelligent network service verifies from the database which is the real number that corresponds to the identifier of the personal user. The service calls the subscriber to different numbers in a given order and connects the call to the subscriber's answer. The subscriber making the call does not know the real location of the subscriber he is calling. The order that is given to investigate the called party is optional, but obviously, the phone number of the workstation should be given the highest priority. If the user has not. registered through the workstation, possibly you can find it in the next number and thus avoid unnecessary signaling and the delay of the call.

Because all subscriber data is recorded in the same location at the service data point 11, Figure 1, subscriber management is easy. It is also possible that the subscriber to the service defines the order of priority of the numbers in which it can be located. The transactions to end the call at the workstation and start at the service station are as follows (Figures 3, 4, 5, and 5).

When the call ends at the workstation, the call process comprises two stages: first, you have to locate the intelligent network and then the subscriber called, controlled by the intelligent network. In this case, the invoice of the call can be in such a way that the subscriber B, that is to say the subscriber to the service, pays the greater part of the costs and the subscriber A who calls, pays a certain basic payment. Another option is to bill the subscriber A more than the basic charge, in which case a voice message will be sent informing him of the cost of the call. Actual billing is then made based on the billing records. The subscriber A who calls, who could be a subscriber of the network (POT) of an old common telephone or an ISDN subscriber, dials the number of the intelligent network service + the identifier of the personal user on his telephone. The number can still be the aforementioned 02-08-445566. The exchange is identified from the service number 0208, ie an intelligent call and transmits the call to the service switching point 13, which starts the exchange of messages with the service control point 12 and transmits the user's identifier 445566 to the service logic, which controls the call from this point forward. The logic of the service verifies from the database 11 which numbers correspond to the user's identifier and which is the order in which the subscriber B can be located. With this it is discovered that the subscriber B registered in the telephone of the station of job. The first stage is concluded, that is, the intelligent network was given access and the service knows the encrypted IP address of subscriber B and the ISDN access number.

The second stage comprises the transmission of the call to the telephone of the work station. This occurs so that the call is first transmitted to access 4 and the IP number of subscriber B is made known. From there, the access decodes the IP number in an internet address and establishes the connection of the voice with the station correct work 5. Finally, the access switches the connection between the ISDN network and the data network. There are at least two different ways to transmit the call to access 4.

In the first instance, the access number and the IP address are in the message of the initial address of the ISUP protocol (IAM) placed in the reserved field for the number C. The number C means as what is known as the number that is obtained in the conversion of the number by the service of the intelligent network from the database. Therefore the number A is the number of the calling subscriber, the number B is the number dialed by the calling subscriber, the, which contains the personal identifier of the subscriber B and the number C is the real number extracted from the base of data to where the call will be sent. In this case, the number C is "the access number + the IP address coded in ten digits". This first method is the dependent operator.

The second instance uses the fact that ISDN allows the use of an extra field in address messages such as the IAM, whose field identifies the different entities behind the ISDN address. In this way the access number is placed in the reserved field for the C number of the initial address message and the IP address is placed in the field of the sub-address related thereto. The IN solutions of some manufacturers, such as the applicant, have considered the transmission of information to an extra field and the reading of this field.

In both cases, the access number routes the call to the correct access. The access number can be the PBX (Private Branch Exchange) type of number or a combination of a special route prefix and access information. The coded IP number comes transparently through the ISDN network to the correct access 4, in which it reads it from the field of the number C or from the extra field. From then on, access is able to route the call based on the internet address to the correct workstation or PC 5.

Then the case is considered when the call is placed from a telephone connected to a computer 5 (figure 1). In this instance, the problem is billing, since from the point of view of the intelligent network, the starting point an «y '~ < . '- f ^ i "» ^^? t \ .. * »; of the call in the access and the real subscriber can not be easily identified behind the access. Therefore, an identification procedure should be introduced in order to bill the call to the correct person. For example, this can be implemented as follows: First, the subscriber dials the service number of the intelligent network and its personal user identifier, based on which the service identifies the subscriber. This step can be free, the sequence of the number can be, for example, 0800-02-09-445566, in which the part of the 0800 number of the service discloses the reverse billing; 02 is the identifier of the operator and 09 the identifier of the service. The 445566 is the identifier of the personal user. After this, billing is no longer a problem. Finally, the subscriber dials the subscriber number to which he is called, which can be a PSTN number.

(Public Telephone Network Switched), an ISDN number or a personal number, if the subscriber is called. The IN network transmits the call to its correct destination, and if the number is a personal number, it verifies it from the database of the real number to which the call is going to be sent. In this way, the real number can also be an internet address.

The method according to the invention, in which all the control functions are centralized in the intelligent network, allows to be able to locate the subscriber through the telephone even if he is busy with his computer. When you move to another computer, before leaving it, you can delete your record from the database of the smart network by dialing the number of the intelligent network service and your personal user ID and by placing appropriate options (mobile phone, signal transmitter, etc.) The old record is automatically deleted alternately when the user registers from a new computer.

To prevent the intelligent network from establishing a conversation connection through a damaged access, the access condition can occasionally be verified and a condition flag assigned. The condition of the signaling device is checked when the call is established and if the signaling indicates a disorder in the access, it is not a question of establishing the call unnecessarily, but the call is placed in a signal transmitter, a mobile phone or another number provided through the database.

It should be further noted that the access control functions and the switching and transfer control functions of the conversation of the telephone connected to .la computer have been implemented in both the access and the computer.

The description and the figures related thereto are only intended to illustrate the subject invention. The different adaptations and modifications are obvious to the experts, within the field and without deviating from the scope and. the basic idea of the invention, as presented in the appended claims.
