Method of signalling subscriber numbers in a telecommunications network
First Claim
1. A process for signalling a call number in a telecommunication network, telecommunication connections being directed from a telecommunication terminal equipment on a transmission side via an origin node, via transit nodes and a destination node to a telecommunication terminal equipment on a reception side, the origin node being arranged in an area of closed numbering and there being inserted into first signalling information, of the telecommunication connection to be set up, a node number designating the origin node, a call number of the telecommunication terminal equipment on the transmission side, a node identity number assigned to the telecommunication terminal equipment on the reception side and a call number of the telecommunication terminal equipment on the reception side, comprising the steps of:
- checking in nodes involved in a setup of the connection on the basis of the node number of the origin node and on the basis of the node identity number of the destination node whether the call number of the telecommunication terminal equipment on the transmission side is to be modified;
supplementing the call number of the telecommunication terminal equipment on the transmission side in a node in an area of closed numbering which neighbors an area of open numbering by an area identity number designating the area of closed numbering; and
not supplementing the call number of the telecommunication terminal equipment on the transmission side in nodes of open numbering following the area of closed numbering.

Abstract
In the telecommunication network, telecommunication connections are directed from telecommunication terminal equipment on the transmission side (A) via an origin node (ON), via transit nodes (TN1, . . . TN7) to telecommunication terminal equipment on the reception side (B). An origin node number, the A call number, the destination node identity number and also the B call number are inserted into signalling information of the connection to be set up. In the nodes involved in the setup of the connection it is checked whether the A call number is to be modified. In some cases, the A call number may be supplemented and in other cases it may be supplemented and abbreviated.

5. An arrangement for signalling a call number in a telecommunication network, telecommunication connections being directed from telecommunication terminal equipment on a transmission side via an origin node, via transit nodes and a destination node to telecommunication terminal equipment on a reception side, the origin node being arranged in an area of closed numbering and there being inserted into first signalling information, of the telecommunication connection to be set up, a node number designating the origin node, a call number of the telecommunication terminal equipment on the transmission side, a node identity number, assigned to the telecommunication terminal equipment on the reception side, and a call number of the telecommunication terminal equipment on the reception side, comprising:
-
means for checking in nodes involved in a setup of the connection on the basis of the node number of the origin node and on the basis of the node identity number of the destination node whether the call number of the telecommunication terminal equipment on the transmission side is to be modified; and means for supplementing the call number of the telecommunication terminal equipment on the transmission side in a node in an area of closed numbering which neighbors an area of open numbering by an area identity number designating the area of closed numbering, and not supplementing the call number of the telecommunication terminal equipment on the transmission side in nodes of open numbering following the area of closed numbering.

6. A process for signalling a call number in a telecommunication network, telecommunication connections being directed from a telecommunication terminal equipment on a transmission side via an origin node, via transit nodes and a destination node to a telecommunication terminal equipment on a reception side, the origin node being arranged in an area of closed numbering and there being inserted into first signalling information of the telecommunication connection to be set up a node number designating the origin node, a call number of the telecommunication terminal equipment on the transmission side, a node identity number assigned to the telecommunication terminal equipment on the reception side, and a call number of the telecommunication terminal equipment on the reception side, comprising the steps of:
-
checking in nodes involved in a setup of the connection on the basis of the node number of the origin node and on the basis of the area identity number of the destination node whether the call number of the telecommunication terminal equipment on the transmission side is to be modified; supplementing the call number of the telecommunication terminal equipment on the transmission side in a node in an area of closed numbering which neighbors an area of open numbering by an area identity number designating the area of closed numbering; not supplementing the call number of the telecommunication terminal equipment on the transmission side in nodes of open numbering following the area of closed numbering; abbreviating, provided that the origin node and the destination node are assigned to a first area having a first area identity number and a second area also having said first area identity number, respectively, and provided that there is at least one further area having a second area identity number arranged between the origin and destination nodes, the first signalling information with the call number of the telecommunication terminal equipment on the transmission side, supplemented by the first area identity number of the origin node, in the destination node, or in a node preceding the destination node and assigned to the second area of the destination node, by the first area identity number of the origin node; checking, after the setup of the telecommunication connection from the telecommunication terminal equipment on the transmission side to the telecommunication terminal equipment on a reception side, the second signalling information in the nodes involved in the setup of the connection on the basis of the area identity number of the destination node and on the basis of the area identity number of the origin node to ascertain whether the call number of the telecommunication terminal equipment on the reception side of a call is to be modified; and not modifying the call number of the telecommunication terminal equipment on a new transmission side, that was previously the reception side, in a transmission of the second signalling information such that the call number of the telecommunication terminal equipment on the new transmission side is routed to the telecommunication terminal equipment on a new reception side, that was previously the transmission side, with abbreviations or supplements.
