A communications network performs a variety of maintenance actions. One of those actions is rerouting of a connection path. A feature called "dynamic resource management option" allows the network or the called party of an active connection to initiate a resource change procedure when needs arises. The resource change can also be achieved by rerouting the existing path of the active connection. However a maintenance action taken in one network domain is only effected within the same domain, because a different domain may have different maintenance procedures. Telecommunication connections often span more than one domain and a request for resource adjustment must be considered differently for a proper maintenance action. A resource change indication message includes a flag to indicate the message originated within or outside the domain. By observing the flag, it is possible to decide on a proper maintenance procedure.
