ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a procedure and to a system for the setup of specially rated calls between two predetermined subscriptions. Moreover, the invention relates to the setting up of a specially rated call between said subscriptions.
BACKGROUND OF THE INVENTION
Call setup in a telephone network is normally based on a number selection made by a calling subscriber, in other words, a calling subscriber selects via his/her terminal equipment the subscriber number of a called subscription, on the basis of which the switchboard and exchange system of the telephone network connects the calling subscriber with the called subscriber. In the case of this kind of normal call setup, the calling subscriber pays for the calls he/she has made a price in accordance with the general tariffs valid at the time.
In the existing telephone network, a known practice is to use service numbers common to all callers, for instance the so-called free numbers starting with 9800-, 0800- or 9700-, and the chargeable service numbers staring with 0700-, 9600- or 0600-, and e.g. the short numbers used for number inquiries. However, such service numbers are not actual subscriber numbers, but the calls made to these numbers are redirected by the switchboard and exchange system of the telephone network to actual subscriber numbers behind the service numbers. When calling such a number, the calling subscriber does not know the connected subscriber's number because the number is changed and the call is redirected in the telephone network. In the call setup chain, the service number is a so-called C-number. Calls to such service numbers are usually either free or rated at a price substantially higher than normal call tariffs.
SUMMARY OF THE INVENTION
The object of the present invention is to achieve in the telephone network a new type of procedure and system for call control and to meet a need observed recently in the telecommunication business for calls especially between certain predeterminable subscriptions. A further object of the present invention is to present a procedure that allows said calls to be set up using a predetermined call number common to all subscribers, on the basis of which the calls can also be assigned a price below normal tariffs. Such calls could be e.g. calls made within a family or a small enterprise e.g. between a wired network subscription and/or an optional number of mobile subscriptions. In this case, the specially rated telephone communication would comprise calls from a specified wired network subscription to a specified number of mobile telephone subscriptions and vice versa, calls between specified mobile telephone subscriptions and also between wired network subscriptions.
A further object of the invention is to achieve a service in which the customer is able to define a pair or set of desired subscriptions between which the calls are invoiced at a price below the normal tariff.
As for the features characteristic of the present invention, reference is made to the claims.
In the procedure of the invention, a specially rated call, generally cheaper than the normal tariff, is set up between two subscriptions. According to the invention, the subscriptions are predetermined and the procedure is implemented as follows. First, a common call number differing from the subscriber number is reserved for all subscriptions. The common call number may consist of two parts and have the form ABCDER, where the prefix part ABCDE is a digit series common to all, while R is an integer in the set [0, 1, . . . , N)]. Further, a subscriber number pair between two subscriber numbers is formed, between which a specially rated call is set up, and the number pair is stored by means of a storage device. The number pair can preferably be stored in a suitable database or an equivalent component in the telephone network. After this, calls to the common call number are directed to a checking device, by means of which the second subscriber number corresponding to the subscriber number of the calling subscription is determined. Finally, the call is connected to the subscription corresponding to the second subscriber number. Finally, invoicing data determined on the basis of the common call number is given to the invoicing system, so that a price preferably lower than the normal call price will be charged for the call.
The advantages of the present invention as compared with prior art include the fact that the system does not require any substantial system changes in the telephone network. In addition, calls between predetermined subscriptions can be rated according to a special tariff and the charges can be easily and flexibly included in the normal invoicing.
Moreover, the invention allows the same tariffs to be applied to calls in either direction, i.e. from a mobile station to a wired network subscription or vice versa, or, on the other hand, the price may be different depending on direction. Furthermore, the invention makes it possible to offer the customer a specially rated data connection for communication between a pair or set of computers.
In a preferred embodiment of the present invention, the pair of subscriber numbers to be considered is selected on the basis of a suffix part of a common call number. Further, subscriber numbers entitled to specially rated calls are stored in a database and the calling subscriber's right to specially rated calls is verified via reference to the database on the basis of the calling subscriber's subscriber number.
There are several alternative solutions for forming a subscriber number pair. A subscriber number pair can be established between a wired network subscription and a mobile communications network subscription. In addition, a subscriber number pair can be established between a wired network subscription and several mobile communications network subscriptions, in which case the subscriber number pair is assigned a separate common call number in which the suffix part determines the subscriber number pair to be considered so that a call made from the wired network subscription is directed on the basis of the suffix part of the common call number to the subscription corresponding to the mobile subscriber number defined in the subscriber number pair and a call made from each mobile subscriber number is directed to the subscriber number corresponding to the wired network subscriber number defined in the subscriber number pair. This makes it possible to form a kind of specially rated group in which a specially rated call can be made from a wired network subscription to several mobile network subscriptions and from each mobile subscription in the group to one and the same wired network subscription. Furthermore, it is possible to establish a subscriber number pair among a set comprising a wired network subscriber number and a plurality of mobile network subscriber numbers so that a call made form any one of the subscriber numbers to the common call number is directed on the basis of the suffix part of the common call number to the subscription corresponding to the second subscriber number corresponding to the calling subscriber number in the set of subscriber numbers. This again provides the possibility to form a kind of specially rated network comprising a number of subscriptions which can be selected either from a wired network or from a mobile communications network and between which it is possible to establish specially rated number pairs according to free selection.
Moreover, the present invention relates to a system for setting up a specially rated call between two predetermined subscriptions in a telephone network, which may comprise a mobile communications network, a wired telephone network, some other telecommunications network or a combination of these, between two subscriptions. According to the invention, the system comprises a storage device in which, in addition to the predetermined subscriber number pairs and the corresponding common call number, it is also possible to store a list of subscriber num
