Abstract

A system and a method are provided for connecting telephone calls directly on the basis of a text query call from a user (1). A special operator centre (3) establishes a database (5) that contains customer profiles. Customers who wish to receive telephone calls e.g. from public users (1), register such customer profiles in the operator centre (3). Any customer profile will contain a telephone domain name (PHONENAME) and at least one destination telephone number. When a user sends a text message, he must indicate a telephone domain name (PHONENAME) and an operator centre code (2001). In the operator centre (3) reached by means of the code (2001), the database (5) is searched, and a destination telephone number corresponding to the indicated domain name is used to establish a call to that destination, and then the user (1) is connected to the destination directly.

Claims

1. A method for connecting telephone calls in digital telephone systems, in which method a user (1) sends, using a text-based message service, information to an operator centre (3), on the basis of which information a destination telephone number is found in a database (5) in said operator centre (3), and a call is connected between the user (1) and a desired destination, characterized by

establishing in said operator centre database (5) a customer profile base for customers having acquired from the operator a right to respective telephone domain names (PHONENAME), said customer profile base containing at least one destination telephone number for every telephone domain name, and

the users (1) sending said information in the form of a message consisting of at least a telephone domain name (PHONENAME) and an operator centre code is (2001), so that said message is routed via at least one local exchange (2) to the operator centre (3) due to said operator centre code (2001), and in the operator centre said database (5) is searched for a desired domain name and at least a corresponding destination telephone number, a destination thereafter being called from the operator centre by means of said destination telephone number, while another call is routed to the user (1), and the connection is established directly.

2. The method of claim 1, characterized in that said operator centre (3) is connected to a network by means of an Application Programming Interface (6), using a standardized set of commands to establish connections between the user (1) and the destination in any sequence defined by service logics or control actions.

3. The method of claim 2, characterized in that said operator centre (3) further operates to provide voice or messaging prompts as defined by said service logics or control actions.

4. The method of claim 2, characterized in that said operator centre (3) further operates to collect and forward, as needed, charging information to billing centres.

5. The method of claim 1, characterized in that said operator centre (3) collects data regarding a user'"'"'s (1) location from said local exchange (2), and from these data the operator centre (3) orders connection of the call to a nearest local telephone among telephones having destination telephone numbers in a customer profile identified by a telephone domain name stated in the message from the user (1).

6. The method of claim 1, characterized in that the operator centre (3) collects data regarding a user'"'"'s (1) location from the local exchange (2), and in accordance with a pre-programmed decision algorithm said operator centre (3) returns to the user (1) a message with at least two alternative choices regarding destination connection.

7. The method of claim 6, characterized in that the message with choices is a text message.

8. The method of claim 6, characterized in that the message with choices is a voice message stating the called telephone domain name (PHONENAME) and dialling choices for alternative call destinations.

9. The method of claim 1, characterized in that the message from the user (1) contains a pre-code (NAM) for the purpose of distinguishing this message from messages to the same operator centre (3) regarding other services offered by that operator centre.

10. The method of claim 1, characterized in that when a certain customer profile contains a conference call instruction linked to a certain telephone domain name (PHONENAME), he operator centre (3) automatically connects a conference call between the user (1) and at least two other subscriptions who may not be customers.

11. The method of claim 1, characterized in that when a first call connection has been established by the operator centre (3) between a user (1) and a first domain name destination, the user (1) sends another text message containing another telephone domain name to invoke another destination telephone number from the database (5), and when this new destination call has been connected from the operator centre (3), the first call connection and the new call connection are linked to form a conference call.

12. The method of claim 1, characterized in that a customer profile base in the operator centre database (5) is provided with variable parameters like location and time, so that a corresponding destination may vary with respect to such parameters.

13. The method of claim 1, characterized in that an operator centre code (2001) is selected for mnemonic or easy-dialling purposes, like 6263 for NAME in a standard telephone keyboard.

14. A digital telephone system for connecting calls, including user (1) telephones having an option for using a text-based message service, local exchanges (2) and an operator centre (3) having a database (5), characterized in that

said database (5) includes a customer profile base for customers having acquired from the operator the right to respective telephone domain names (PHONENAME),

said customer profile base contains at least one destination telephone number for every domain name,

said operator centre (3) also includes

means (10) for fetching from said database (5) a destination telephone number that corresponds to a telephone domain name (PHONENAME) included in said message, and

means (10) for calling the destination telephone number and the user number, and for connecting the user (1) directly to a corresponding destination.

15. The system of claim 14, characterized in that said operator centre (3) is connected to a network by means of an Application Programming Interface (6), using a standardized set of commands to establish connections between the user (1) and the destination in any sequence defined by service logics or control actions.

16. The system of claim 15, characterized in that said operator centre (3) further comprises means (9) to provide voice or messaging prompts as defined by said service logics or control actions.

17. The system of claim 15, characterized in that said operator centre (3) further comprises means (10) to collect and forward, as needed, charging information to billing centres.

18. The system of claim 14, characterized in that said operator centre (3) comprises means (10) for collecting data regarding a user'"'"'s (1) location from said local exchange (2), and from these data to order connection of the call to a nearest local telephone among telephones having destination telephone numbers in a customer profile identified by a telephone domain name stated in the message from the user (1).

19. The system of claim 14, characterized in that the operator centre (3) comprises means (10) for collecting data regarding a user'"'"'s (1) location from the local exchange (2), and means for returning, in accordance with a pre-programmed decision algorithm, to the user (1) a message with at least two alternative choices regarding destination connection.

20. The system of claim 19, characterized in that said means for returning a message is a voice machine (9).

21. The system of claim 14, characterized in that the operator centre (3) contains a conference bridge (8) for connecting conference calls between the user (1) and at least two other subscriptions that are not necessarily customers of the operator centre (3).

22. The system of claim 14, characterized in that a customer profile base in the operator centre database (5) is provided with variable parameters like location and time.

23. A call request signal for use when connecting exchanges (2) and operator centres (3) for direct connection of calls in digital telephone systems, characterized in that the signal is a signal for a text-based message service, and comprises at least

a telephone domain name (PHONENAME), and

an operator centre code (2001).

24. The signal of claim 23, characterized in that it comprises also a pre-code (NAM) to indicate a specific service offered by an operator centre (3).

25. The signal of claim 23, characterized in that the telephone domain name contains also an Internet top domain indication.
