Telecommunication system and a method for matching the numbering schemes of two telecommunication systems
First Claim
1. A method for matching the numbering scheme of a telecommunication system with the numbering scheme of another telecommunication system at an interface between the systems, the numbering scheme of the first telecommunication system comprising an X-bit binary subscriber/equipment specific identity code, and the numbering scheme of the second telecommunication system comprising a Y-decimal subscriber/equipment specific identity code, characterized in that in the second telecommunication system the subscriber/equipment of the first telecommunication system is assigned a Y-decimal identity code obtained by converting the X-bit binary identity code of the subscriber/equipment into a decimal number comprising no more than Y-1 decimals, and by introducing one or more system identification decimals into the obtained decimal number at a predetermined position, the system identification decimal(s) indicating that the subscriber/equipment identity code belongs to the subscriber/equipment of the first telecommunication system.

Abstract
The invention relates to a telecommunication system and a method for matching the numbering schemes of telecommunication systems. The telecommunication system comprises a transmission network comprising at least one mobile exchange (MSC1, MSC2) associated with a subsystem (BUC, BU1-BU6), the calls of subscribers (MT1-MT6) in the subsystem being routed through the transmission network and the mobile exchange. A numbering scheme of the subsystem comprises an X-bit binary subscriber identity code (PID) and a numbering scheme of the transmission network comprises a Y-decimal subscriber identity code (MSIN). In the transmission network the subscriber (MT1-MT6) of the subsystem is assigned a Y-decimal identity code comprising a decimal number derived from the X-bit binary identity code of the subscriber and having no more than Y-1 decimals. At least one system identification decimal is introduced into the obtained decimal number at a predetermined position to indicate that the identity code belongs to the subscriber (MT1-MT6) of the subsystem.

4. A telecommunication system comprising a transmission network utilizing a first numbering scheme and comprising at least one mobile exchange (MSC1, MSC2) connected to a subsystem (BUC, BU1-BU6) utilizing a different numbering scheme, the calls of subscribers (MT1-MT6) in the subsystem being routed through the transmission network and said mobile exchange, characterized in that the numbering scheme of the subsystem comprises an X-bit binary subscriber/equipment identity code (PID), and the numbering scheme of the transmission network comprises a Y-decimal subscriber/equipment identity code (MSIN);
- and that in the transmission network the subsystem subscriber/equipment is assigned a Y-decimal identity code comprising a decimal number derived from the X-bit binary identity code of the subscriber/equipment and including no more than Y-1 numbers, at least one system identification decimal code being added to the obtained decimal number at a predetermined position, the system identification code(s) indicating that the identity code belongs to the subscriber/equipment (MT1-MT6) of the subsystem.
