DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention is directed to a method for accomplishing a telecommunication connection from a mobile communication network A-subscriber connection.
2. Description of the Related Art
It has heretofore been possible to form a group of subscribers, for example inside a company, using PABX (private automatic branch exchange) extension numbers to enable such subscribers to make internal calls inside the group using the PABX extension numbers. When a subscriber in the PABX group has made a call using an extension in the group, the extension number and the caller number are transferred in the call initiating message through the base station to the mobile telephone exchange, wherefrom a subscriber register connected to the exchange and using the information received in the initiating message is checked to verify that the subscriber has the right to use the extension number, after which the number is transformed to a PSTN (public switched telephone network) subscriber number using a number transformation table. The exchange gives a separate announcement to billing information about this call, so that the call can be billed in a special way. The problem of implementations like this is that they are restricted to a specific PABX group or to a specific base station area.

DETAILED DESCRIPTION OF THE PRESENTLY PREFERRED EMBODIMENTS
Mobile station subscribers call repeatedly to a same group of numbers, which may include a certain client, home, an institution or similar. To make these calls even more convenient, the operator can give to the mobile phone subscriber abbreviated numbers for often made or repeated calls which can be billed differently, as for example more profitably than calls which are made using normal subscriber numbers.
In the method of the invention the mobile phone subscriber's calls can be grouped in billing using starting numbers.
The object of the invention is a method for accomplishing a connection from a mobile communication network A-subscriber connection, to a mobile communication network or other telecommunication network B-subscriber connection, for thus making a call with a mobile station. Referring now to FIG. 1, a first mobile communication network 100 includes an A-subscriber mobile station 102 and a base station 104 with a limited coverage area, to which the A-subscriber mobile station has a connection, a B-subscriber.sub.-- 1 mobile station 110, and a base station 108 with a limited coverage area, to which the B-subscriber.sub.-- 1 mobile station has a connection, and a first mobile telephone exchange 106, connected to base stations 104 and 108, to switch the connections within the first mobile communication network 100 and from it to other communication networks and vice versa.
In another embodiment of the present invention, the first mobile communication network 100 may be connected to a second mobile communication network 200, having a B-subscriber.sub.-- 2 mobile station 206, and a base station 204 with a limited coverage area, to which the B-
