Abstract: The management of a telephone network is enhanced by arranging an associated operations system so that it correlates related messages, e.g., alarm messages, that may be received from different elements forming the network. Advantageously, then, related messages may be displayed together on the display of a terminal, rather than intermingling those messages on the display with other unrelated messages in some predetermined order, such as the order in which the messages are received. In this way a user may view and readily determine the underlying cause which prompted the generation of displayed correlated messages.

Abstract: A method for implementing call-gapping controls in a telecommunications system supporting ported directory numbers comprises receiving control messages at switches and other network elements, which messages include information relating to the type of controls and parameter information for one or more options permitting present or downstream local number portability (LNP) queries. Based on such received control information, a switch or other network entity seeks to process the call toward completion using dialed number and/or corresponding LNP information, or cancel the call in the interest of overall network efficiency. Use of traffic information allows system operators and network databases to impose policies and practices such as use of dialed number for routing notwithstanding the availability of location routing number information.
