Telephone network system and method for doing so

FIELD OF THE INVENTION The present invention relates to telephone technology and more particularly to a system and method for using telephone networks of different telecommunications operators from a subscriber line through an intelligent network service.

Background of the Invention

The telephone system in its basic form involves the user dialing a number to reach another telephone user. When he answers the phone, a voice connection is established between the users. In addition, there are many services in the telephone system, e.g., dialing numbers starting with a particular number, e.g. 0800, 0900, 800, 900, can be used by the user either without paying any toll (toll-free) or priced higher than a normal call. The requirement to support and provide various services has led to the development of telecommunications networks. in the direction of IN (Intelligent Network). An intelligent network can be defined as an architecture that can be applied to most telecommunication networks, regardless of network technology. Its purpose is ♦ to create, control and harness value-added telecommunications services.

A dream. One feature of an intelligent network is to provide modular functions independent of the service being used, which can be interconnected as components to create new services, making it easier to define and design new services. Another distinctive feature is the 'independence of the provision of services'. The services are not separated from the physical network structure only, so they can be. distributed.

CCITT has defined the Intelligent Network Conseptual Model (INCM) in Recommendation CS-1 (Capability Set 1). The model consists of four levels, of which 2 111679 each represent an abstract view of the opportunities offered by the intelligent network. The second highest level of the model is the Global Functional Plane and includes a view of the Intelligent Network as a Service Independent Building Block (SIB) that assembles the desired service features and services using service logic. This level also includes network-wide basic call processing (BCP) as well as initialization and translation points (POI) and POR (Point of Return) between BCP and SIBs. For example, WO-9615633 A1 discloses a description of the physical architecture of an intelligent network. For example, as an intelligent network service, it is possible, subject to certain limitations, to route a call from the first network to the second network. Such a solution is described in EP-726682.

Calls to service numbers are routed to a call routing information base called a service control point (SCP). The numbers are usually national. The caller can inquire about account information, information about the company's products and services. When a predetermined call is made, the call is routed through the call centers and service access point (SSP) to the SCP using common channel signaling. The SCP must be configured to determine which of the plurality of addresses a particular call is to be routed to. Often a particular service can be accessed by dialing a specific number and different numbers corresponding to different services. Alternatively, the subscriber may also select individual numbers from an additional number, e.g.

To control how calls are routed between numerous * alternative subscriber addresses, the caller's number, network, SCP, SDP, and subscriber data are utilized to the full. The subscriber usually pays a fixed fee for the use of the telephone and, depending on the length of the call, the call fee to the network operator with whom the subscriber has an agreement. In the case of landline telephones, this applies to 3 111679 in general. You can use your phone to make calls to another operator, for example long distance calls, but not to local calls because they could not be prefixed to differentiate them between calls. Usually a service number is added to the service number, after which the call can be connected to the respective service, which is a B number.

Of course, it is possible to resolve the issue by agreeing that the calls of a particular number holder will be billed only by the operator agreed with the subscriber, but in many countries this is not possible. To enable this, the method and arrangement of the invention solve the problem in a new and unambiguous way.

Figure 1 illustrates in more detail a basic service in an intelligent network, namely, a number conversion service, which is illustrated before the implementation of the invention. Only the relevant physical objects are shown in the figure. Subscriber 1 (landline or mobile subscriber) dials, for example, 800 + ABCD (ABCD is a number sequence). The call control function of the exchange 2 recognizes from the 800 prefix that it is an intelligent network call, whereby the intelligent network service is requested through the SSP 3 of the intelligent network switching point. It sends a request with 800 + ABCD to the control point SCP 4 using common channel signaling. The respective service program in SCPr 4 looks at the SDP file 5, which number of the regular telephone network corresponds to the number 800 + ABCD. In this example, it is number 291 7041. The SCP returns this number to the SSP, which further encapsulates it in the call control of the exchange, which then routes the call to this number. When assigning a number to the SSP, the SCP also provides charging information for the call. Your Service Data Function (SDF), which is physically located in the SCP, the SSCP (Service Switching and Control Point (SSCP) consisting of the SCP and the SSP in one node) or the SDP, is a database , which contains subscriber-specific information in a single subscriber record. The record thus contains at least an A-number and a balance. In addition to these, ·, * may contain e.g. black / white information, subscriber short number, statistics and help information. The statistics may include how much the subscriber has called, who made the call, the duration of the calls, etc. The help information indicates how to proceed when certain conditions are met. The condition may be that the set price is exceeded, etc. The basic database is created by the operator through the service management system SMS 6.

It is known to use the exchange's subscriber database in the fixed network and in the mobile telephone network such as the GSM network the Home Location Register (HLR), where the permanent subscriber information is stored. The above-mentioned AAB service accesses a database of an intelligent network which contains an identification code and a PIN number.

All of these subscriber databases have in common that they are created and updated by the operator of the network in question. It is known that various subscriber-specific parameters can be set in the database. Thus, for example, the network operator may set a parameter in the subscriber record that prevents the subscriber from making, for example, international calls or accessing certain services implemented via the intelligent network, such as Entertainment Services. In particular, entertainment services provided through the intelligent network have proved problematic and may have been subject to a certain time limit upon which the call is interrupted. It is possible to block access to numbers starting with certain prefixes.

Figure 2 is a schematic representation of one solution utilized in the invention over a telephone network. In Figure 1, a subscriber interface that wants to connect to another operator's intelligent network is marked with l. The components of the telephone network are exchanges 2, 3 which connect the calls between two long-distance subscriber lines 1 and 5. The telephone exchange 2, 3 has a connection to an intelligent network 7 consisting of e.g. · · · · · · · · · · · · · · About SSP and SDP 3,4, the signaling between which is · · · · · · · · · · · · · · · · Common Signaling SS7. A table is formed in the SDP 5, which contains information about the subscriber line involved in the service, as well as any information about whether he has any remaining balance.

The connection between the local loops and the exchange may be wired or wireless, preferably a fixed network subscriber in a network operated by a particular operator.

»The system is designed in such a way that the subscriber may, if he so wishes, utilize any presumed teleoperator or other operator, that is, the subscriber may select an active operator of his choice, for example because the price is cheaper, etc. When a subscriber connection is which is predetermined, at least initially, so that the information contained therein can be routed from the subscriber interface to the desired intelligent network, and to the intelligent network of the desired operator, and the call center is aware that such a number is to be routed the intelligent network. In an intelligent network, the call is routed, for example, to a database SDP, which checks that the subscriber connection has the right to use the operator, i.e. it is in the database table. When this is the case, the information is sent to the SSP, which establishes a register mode where numbers can be received and switched to the exchange, whereby a dial tone can be provided to the subscriber line, after which the desired B subscriber number can be selected from the subscriber line. Thereafter, a voice connection is established between the caller and the called subscriber, utilizing normal call routing. When the call is finished, the connections are disconnected. After the call, a key can be selected from the subscriber interface 1 to disconnect the connection to the intelligent network 7 if such a procedure is desired.

In order to implement one embodiment, the basic network features are utilized both by an IN service function by means of which the A-subscriber interface, such as a fixed network telephone, is registered in the IN database in the SDP. The phone can be used for two or more functions: The user receives a subscription that works in the same way as a traditional network (hands-free calling followed by dialing) and a feature that notifies you of the money remaining at the beginning of the call and then hands-free.

Billing is done by paying a monthly subscription fee and a possible Hotline (which automatically connects to the intelligent network within a certain amount of time after the phone is switched off-hook) to the fixed-line operator, that is, the operator used by the local in most cases, as the only possible operator in the case where the operator is the owner of the network and the network has not been leased to another operator and calls the other network operator selected through the toll-free number (smart network number). The network operator will be paid in advance for calls to the A-number address.

The "pulses" are subtracted from the address according to the current traffic case. When accessing a free call service, such as 0800, during a call, this call will not send the caller down to the network for taxi calls. Calls are monitored by billing records collected from the service, which are collected for post-processing. The post-processing may, if desired, be subject to the necessary verification to ensure billing. Real-time scanning can also be utilized, e.g. by utilizing the solution disclosed in WO-9615633 A1.

The following describes the operation of the invention when using the moon line function. A basic interface with DTMF selection and, if desired, a "Hotline" delay.

The hotline address number is selected as ΟδΟΟχχχ, of which at least one x number, usually the first x, identifies a teleoperator that connects to the IN service of another operator, whereby according to the invention the second teleoperator charges the cost of the call to the subscriber line.

1. The subscriber to the base station picks up the "handset" and hears a special dial tone.

- If you want to use a basic network, you must make the selection immediately. For example, emergency calls.

Otherwise, after a predetermined delay, your hotline will send 0800xxx numbers and subscription A number to the network and forward to the GlobalAccessPCC service, the intelligent network 7.

The costs of 0800 xxx will be covered by an agreement between the operators. The subscriber pays the operator of the basic subscriber line a regular monthly fee + the cost of the hotline.

2. When a call comes in, the GAPCC checks the remaining money on the A-number counter and gives a B answer and a dial tone.

- When the subscriber hears a dial tone, he dials the desired number.

- The GAPCC receives the numbers to verify their correctness and to forward them on the network and to switch on the voice path and transmit the signals required by the network signaling. For example, the cost of a call may be controlled in real time as disclosed in WO-9615633 A1, e.g. by transmitting to the service control point SCP the computed pulses generated during the call as determined by a monitoring request sent by the service control function SCF. Monitoring requests are answered by the Service Switching Function (SSF). The SCP calculates in real time based on pulses and charge information, the cost of the call as the call progresses. The SCP has retrieved subscriber data from the A-subscriber's record database and, if there is information about the cost of the call, for example, how much the call may not cost, the call will be disconnected or otherwise managed. This other procedure is also reported in the record. It may instruct the subscriber to be notified by voice, that the call will be disconnected after a short time, or that the set price limit has been reached or not. The system includes a special subscriber data management logic created at the intelligent network service control point SCP. The database is physically located at the service data point SDP. Subscriber database - ·. broad records are created and deleted by the operator through a service management system SMS, but according to the invention, subscriber records are also created and deleted through a telephone network associated with an intelligent network. Dial-up, read / write and delete are automatic. For example, when a visitor subscriber in a cellular network is updated, the subscriber information is automatically routed to the cellular network 10111679, which creates a subscriber record for that subscriber. From the call control switching telephone exchange, the computed pulses generated during the call can be transmitted to the intelligent network as determined by the monitoring request sent by the service control function SCF, which in real time calculates the price so far formed. The current price is compared with the value specified in the subscriber record and is performed according to the instructions given in the record.

3. The call is terminated in accordance with normal telephone network signaling standards.

4. When the account balance is exhausted, the subscriber will be notified and the call will be terminated in accordance with the specified delay or the call will continue, with the money in the account being notified. When the money runs out, a bulletin is issued and the call is disconnected.

5. However, if there is no money in the account balance, the subscriber may use the basic network as before and pay for the time and calls he uses, according to the carrier's billing.

6. The subscriber shall pay the balance of the account either by direct payment to the GAPCC operator or by special account A from which the money will be transferred to the counters of the balance.

The connection to the intelligent network can be made, for example, by a hotline function or a hotline function with a delay or by dialing or reporting a predetermined number to the exchange. There may be several intelligent networks, only one or more of which are used »; for the purpose of the invention. Telecommunications operators themselves may have one or more intelligent networks with multiple SSPs, SDPs and SCPs.

Figure 3 illustrates the above-described procedure of the invention when a subscriber calls an intelligent network with a predetermined 11111679 teleoperator control number from a predetermined subscriber interface authorized to use the function.

The foregoing description and the accompanying drawings are merely intended to illustrate the present invention. Various variations and modifications of the invention will be apparent to those skilled in the art without departing from the scope and spirit of the invention set forth in the appended claims.
