| 摘要 |
The invention relates to changing the characteristics of a signalling link in a communications system comprising at least two signalling points (A. . . D) and at least one signalling link through which signalling information is transmitted from a signalling point to an adjacent signalling point. In the method, the signalling traffic to be relayed is monitored at a signalling point and a modification procedure intended for modifying user connections is performed, in which a modification request message including an identifier value for identifying the object of modification is sent to an adjacent signalling point. In order for the system to be capable of flexibly adapting itself to a temporary increase in the signalling load, a set of identifier values that are used only for identifying the signalling links are allocated in advance to the signalling links between adjacent signalling points, and when the signalling traffic meets a given predetermined condition, said modification procedure is used for modifying a signalling link by inserting in the modification message to be sent an identifier value that belongs to said set.
