ABSTRACT:
In a method for the control of a connection in a communication network comprising a plurality of nodes (MSC, TSN, MG), a connection (CO) is established stepwise between nodes (MSC, TSN, MG). At least two of the nodes (MSC, TSN, MG) are adapted to insert an entity into the connection (CO), the entity affecting the connection quality, or to remove an entity affecting the connection quality from the connection. An indicator is forwarded between nodes controlling the connection (CO) wherein the indicator indicates whether the connection (CO) comprises an entity affecting the connection quality. A node which decides to insert an entity into the connection or remove an entity adjusts the indicator accordingly before forwarding it to a further node (MSC, TNS, MSC′) controlling the connection (CO). A node (MSC, TSN, MSC′) controlling the connection (CO) checks the value of the indicator when it performs a decision to insert or remove an entity. Nodes and program units for performing the method are also described.
